Recovery as an explanatory mechanism in the relation between acute stress reactions and chronic health impairment.

Abstract: This contribution aims at shedding light on the mechanisms that may underlie the relationship between acute reactions to stressful work characteristics and employee health in the long run. Recovery, a process of psychophysiological unwinding after effort expenditure, is considered a vital link in this relationship. This link is explained on the basis of assumptions from theories on effort, recovery, and sustained activation. It is argued that recovery after work (external recovery) is particularly necessitated when recovery opportunities during worktime (internal recovery) are insufficient. It is further argued that two conditions may impede the recovery process by sustaining physiological activation, prolonged exposure to work demands (working long hours) and cognitive stress-related processes (such as rumination). These theoretical assumptions are substantiated by empirical support from previous laboratory and field research. It is concluded that the chronic situation of sustained physiological activation and incomplete recovery is an important pathway to chronic health impairment.

Chiral Architectures from Macromolecular Building Blocks

Abstract: The chiral architectures from macromolecular building blocks were discussed. The conformational dynamics of the helicity and their effect on the (photo)physical properties of the polymers and the induction of helicity in the polymer chain were elaborated. The influence of kinetics on the macromolecular secondary structure and the use of multiple interactions in the hierarchical organization of macromolecules to well-defined supramolecular assemblied were also examined.

The Compulsive Internet Use Scale (CIUS): Some Psychometric Properties

Abstract: The present study aimed to develop a short, easily administered, psychometrically sound, and valid instrument to assess the severity of compulsive Internet use. A set of criteria was determined based on the addiction literature. Next, the internal consistency and convergent validity were determined, and the set was tested as a one-factor solution in two representative samples of heavy Internet users (n = 447 and n = 229) and in one large convenience sample of regular Internet users (n = 16,925). In these three studies, respondents were asked about their online behavior and about problems related to Internet use. In the first study, the Online Cognition Scale (OCS) was included to determine concurrent validity. The newly developed Compulsive Internet Use Scale (CIUS) contains 14 items ratable on a 5-point Likert scale. The instrument showed good factorial stability across time and across different samples and subsamples. The internal consistency is high, and high correlations with concurrent and c...
