Job demands–resources model in the context of recovery: Testing recovery experiences as mediators

Abstract: The aim of the present study was to extend the original Job Demands– Resources (JD-R) model by taking into account recovery as an important mediation mechanism between work characteristics and well-being/ill-health. Specifically, we examined whether recovery experiences—strategies promoting recovery—might have a mediating role in the JD-R model among 527 employees from a variety of different jobs. The results showed that psychological detachment fully mediated the effects of job demands on fatigue at work and mastery partially mediated the effects of job resources on work engagement. Altogether, the results suggest that recovery merits consideration as a mediating mechanism in the JD-R model.

Recovery during the weekend and fluctuations in weekly job performance: A week-level study examining intra-individual relationships

Abstract: For most employees, the weekend offers the opportunity to recover and unwind from demands faced during the working week. In this study, first, we examined which factors contribute to employees' successful recovery during the weekend. Second, we investigated if being highly recovered after the weekend benefits different dimensions of job performance during the week. Using a within-person design we conducted a week-level study with 133 employees over four working weeks. Participants responded to weekly web-based surveys at the beginning and at the end of the working week. Hierarchical linear modelling showed that psychological detachment, relaxation, and mastery experiences during the weekend predicted the state of being recovered at the beginning of the working week. The state of being recovered in turn predicted fluctuations in weekly task performance, personal initiative, organizational citizenship behaviour, and low perceived effort. Our results stress the importance of recovery during the weekend for both the individual and for organizations.

Long-Chain Aliphatic Polymers To Bridge the Gap between Semicrystalline Polyolefins and Traditional Polycondensates

Abstract: Other than their established short-chain congeners, polycondensates based on long-chain difunctional monomers are often dominated by the long methylene sequences of the repeat units in their solid-state structures and properties. This places them between traditional polycondensates and polyethylenes. The availability of long-chain monomers as a key prerequisite has benefited much from advances in the catalytic conversion of plant oils, via biotechnological and purely chemical approaches, likewise. This has promoted studies of, among others, applications-relevant properties. A comprehensive account is given of long-chain monomer syntheses and the preparation and physical properties, morphologies, mechanical behavior, and degradability of long-chain polyester, polyamides, polyurethanes, polyureas, polyacetals, and polycarbonates.

Revealing the Role of Anchoring Groups in the Electrical Conduction Through Single‐Molecule Junctions

Abstract: A combined experimental and theoretical study is presented revealing the influence of metal-molecule coupling on electronic transport through single-molecule junctions. Transport experiments through tolane molecules attached to gold electrodes via thiol, nitro, and cyano anchoring groups are performed. By fitting the experimental current-voltage characteristics to a single-level tunneling model, we extract both the position of the molecular orbital closest to the Fermi energy and the strength of the metal-molecule coupling. The values found for these parameters are rationalized with the help of density-functional-theory-based transport calculations. In particular, these calculations show that the anchoring groups determine the junction conductance by controlling not only the strength of the coupling to the metal but also the position of the relevant molecular energy levels.
