Abstract Background Dutch legislation stimulates active participation of employees in their return-to-work (RTW) process. Earlier research showed that employees, particularly with low levels of education, are not always able to self-direct RTW. Empowering leadership may support this process. This study answers two research questions: (1) What differences and similarities do employers of employees with low versus high levels of education show in their management of RTW? (2) To what degree do the roles of employers in both types of organizations resemble empowering leadership? Methods We performed semi-structured, in-depth interviews with 10 HR professionals and supervisors working at a Dutch university. We also analysed transcripts from a study in which 13 HR professionals and supervisors from multiple Dutch industries (employing workers with low levels of education) were interviewed. We used purposive sampling to recruit participants. For question 1, the transcripts were analysed thematically. For question 2, pattern matching was applied. Results Preliminary results indicate that supervisors of both types of employees, show several similarities in managing RTW, such as the focus on possibilities instead of impossibilities, asking the advice of the occupational physician, and seeking support to increase employability. We also found that supervisors of employees with low levels of education have a stronger tendency to control and steer RTW and feel that possibilities for RTW are limited, while supervisors of high-educated employees tend to engage in dialogue more often and search for possibilities for work adjustments. Empowering leadership seems to be less common among supervisors of employees with low levels of education. Conclusions This study will benefit employers (of workers with both low and high levels of education) who aim to enable employees' self-direction in RTW, and help supervisors to develop more empowering leadership styles. This may lead to more sustainable RTW. Key messages Supervisors of employees with lower levels of education have a strong tendency to control and steer their employees’ return-to-work. Enabling employees’ self-direction in return-to-work requires empowering leadership.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

AbstractThe records of sunspot number, sunspot areas and sunspot locations gathered over the centuries by various observatories are reanalysed with the aim of finding as yet undiscovered connections between the different parameters of the sunspot cycle and the butterfly diagram. Preliminary results of such interrelationships are presented.

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.

Preliminary results reported last year on the ion etching of tobacco mosaic virus indicated that the diameter of the virus decreased more rapidly at 10KV than at 5KV, perhaps reaching a constant value before disappearing completely.In order to follow the effects of ion etching on TMV more quantitatively we have designed and built a second apparatus (Fig. 1), which incorporates monitoring devices for measuring ion current and vacuum as well as accelerating voltage. In addition, the beam diameter has been increased to approximately 1 cm., so that ten electron microscope grids can be exposed to the beam simultaneously.

Ever since Habraken and Economopoulos first employed the term granular bainite to classify certain unconventional transformation products in continuously cooled steels, the term has been widely accepted and used, despite the lack of a clear consensus as to the detailed nature of the transformation products which constitute granular bainite. This paper presents the preliminary results of a TEM investigation of an 0.04 wt% C, copper-containing steel (designated HSLA-100). It is suggested that the term granular ferrite rather than granular bainite is a more accurate description of this multiphase reaction product.Figure 1 is a light micrograph of a sample which had been air-cooled from 900°C to room temperature. The microstructure is typical of that which has been termed granular bainite in the past and appears to consist of equiaxed ferritic grains together with other minor transformation products. In order to examine these structures in more detail, both continuously cooled and isothermally transformed and quenched materials have been examined with TEM. Granular bainite has been found in virtually all samples.
