This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity is analysed. The annual energy yield of a micro wind turbine is estimated and compared using data from a micro-wind turbine wind tunnel experiment and field data. Electrical energy costs are discussed as well as structural integration cost reduction and the potential energy yield could decrease costs. It was found that instantaneous wind direction towards the barrier and the height of observation play an influential role for the results. Wind speed increases in perpendicular flows while decreases in parallel flow, by +35% down to −20% from the reference. The azimuth of the noise barrier expressed in wind field rotation angles was found to be influential resulted in 50%–130% changes with respect to annual energy yield. A micro wind turbine (0.375 kW) would produce between 100 and 600 kWh annually. Finally, cost analysis with cost reductions due to integration and the energy yield changes due to the barrier, show a LCOE reduction at 60%–90% of the reference value. https://doi.org/10.1016/j.jweia.2020.104206
Purpose The purpose of this paper is to investigate possible differences in the degrees of employability, leader–member exchange (LMX) and innovative work behaviours in a comparison between Belgium and the Netherlands. Although neighbouring countries, disparate national cultures between the two are assumed to influence the amount of employability, LMX and innovative work behaviours among their respective working populations. Furthermore, this paper aims to validate a mediation model across the two countries to test whether employability (partially) mediates the relationship between LMX and innovative work behaviours. Design/methodology/approach Data from employees and their immediate supervisors working in small- and medium-sized enterprises (SMEs) in Belgium and the Netherlands supported the hypothesized model. Structural equation modelling was used to investigate the mediation model using a multisource approach. Findings The amount of employability and innovative work behaviours of employees appeared to differ significantly between Belgium and the Netherlands. Furthermore, the results suggested that for both countries a positive relationship with one’s immediate supervisor (LMX) is beneficial in the light of workers’ innovative work behaviours, through its impact on employability, which was found to be a full mediator in this relationship. Research limitations/implications Future studies using a longitudinal approach could give more insight into the model relationships. Moreover, the variation in systems, national contexts and managerial practices in the Euroregion calls for more cross-national comparative scholarly research. Practical implications SMEs often do not employ professionals to manage human resources, that is, supervisors themselves have to carry the responsibility to encourage employees to further develop themselves and to enhance their innovative work behaviours. This while the challenge of more cross-national cooperation encourages a boost for innovations in the Euroregion. Originality/value This study is the first cross-national validation of a mediation model wherein a competence-based measure of employability is incorporated as a possible mediator in the relationship between LMX and innovative work behaviours.
A previous study found a variety of unusual sexual interests to cluster in a five-factor structure, namely submission/masochism, forbidden sexual activities, dominance / sadism, mysophilia, and fetishism (Schippers et al., 2021). The current study was an empirical replication to examine whether these findings generalized to a representative population sample. An online, anonymous sample (N = 256) representative of the Dutch adult male population rated 32 unusual sexual interests on a scale from 1 (very unappealing) to 7 (very appealing). An exploratory factor analysis assessed whether similar factors would emerge as in the original study. A subsequent confirmatory factor analysis served to confirm the factor structure. Four slightly different factors of sexual interest were found: extreme, illegal and mysophilic sexual activities; light BDSM without real pain or suffering; heavy BDSM that may include pain or suffering; and illegal but lower-sentenced and fetishistic sexual activities. The model fit was acceptable. The representative replication sample was more sexually conservative and showed less sexual engagement than the original convenience sample. On a fundamental level, sexual interest in light BDSM activities and extreme, forbidden, and mysophilic activities seem to be relatively separate constructs.
