In the 1990s, patenting schemes changed in many respects: Upcoming new technologies accelerated the shift from price competition towards competition based on technical inventions, a worldwide surge in patenting took place, and the ‘patent thicket’ arose as a consequence of strategic patenting. This study analyzes the importance of patenting versus secrecy as an effective alternative to protect intellectual property (IP) in the inventions’ market phase. The sales figure with new products is introduced as a new measure of the importance of IP protection tools among product innovating firms. Focusing on German manufacturing in 2000, it turns out that patents are an effective means to protect IP in the market, whereas secrecy seems to be rather important for inventions that are not yet commercialized.

A common phenomenon in entrepreneurship is that employees turn away from employment to found their own businesses. Prior literature discusses the former employers’ characteristics that influence the creation of entrepreneurial ventures. An investigation of whether these characteristics also affect the success of the spawned ventures is missing so far. This paper contributes to the literature by showing that entrepreneurial ventures spawned by well performing firms are financially more successful than ventures stemming from poorly performing firms. This suggests that spawned entrepreneurs are able to exploit valuable knowledge from their previous employers which impacts their ventures’ performance positively. The analysis is based on a linked employee–employer data set for the Netherlands for the period 1999–2004. [less ▲]

The fundamental hypothesis related to the distinction between categorical and coordinate processing has been that these two types of spatial relations coding are qualitatively different. Based on Kosslyn’s initial hemispheric specialization theory, they also are hypothesized to rely on different functional networks in the brain which are supposed to have evolved in a way to take advantage of more fundamental hemispheric specializations in order to adapt these hemispheric strengths to the processing of the two different types of spatial relations.

Working memory capacity (WMC) and reasoning abilities—as assessed by figural matrices tests—are substantially correlated. It is controversially discussed whether this correlation is only caused by controlled attention or also by storage capacity. This study aims at investigating storage of partial solutions as a possible mechanism by which storage capacity may contribute to solving figural matrices tests. For this purpose, we analyzed how an experimental manipulation of storage demands changes the pattern of correlations between WMC and performance in a matrix task. We manipulated the storage demands by applying two test formats: one providing the externalization of partial solutions and one without the possibility of externalization. Storage capacity was assessed by different types of change detection tasks. We found substantial correlations between storage capacity and matrices test performance, but they were of comparable size for both test formats. We take this as evidence that the necessity to store partial solutions is not the limiting factor which causes the association between storage capacity and matrices test. It is discussed how this approach can be used to investigate alternative mechanisms by that storage may influence performance in matrices tests. [less ▲]

Workplace bullying is a serious phenomenon that has serious detrimental effects on victim’s health, attitudes, and work-related behavior. Drawing on self-determination theory, we propose that bullying exposure thwarts employee’s need for relatedness with the result of decreased well-being. Studies examining these mechanisms used either a cross-sectional design (Trépanier et al., 2013) or a longitudinal design with (not theoretically justified) long time intervals (i.e., 12-month time lag; Trépanier et al., 2015). Therefore, the aim of our study was to test this mediation in a longitudinal design with much shorter time intervals (i.e. monthly), whether to see if the bullying exposure also shows short-term effects on well-being. A six-wave online survey design with monthly time lag was employed and data were collected among U.S. employees. The sample consists of 1,595 respondents (55.8% females, n=890, ageM = 36.9, ageSD =10.3). Workplace bullying exposure was assessed with the S-NAQ (Notelaers et al., 2018), frustration of the need for relatedness with the Psychological Needs Thwarting Scale (Bartholomew et al., 2011) and well-being with the WHO-5 well-being-index (Topp et al., 2015). Cross-lagged mediation analysis within a structural equation modeling framework confirmed the mediation model: Bullying exposure was significantly related to a change in frustration of relatedness and frustration of relatedness was significantly related to a change in well-being across all waves. The study findings advance the field through showing that bullying exposure has not only a long-term effect on well-being but also a short one, and that this effect is mediated through the frustration of relatedness.

In the literature of the recent past has been reported from time to time by the so-called energy-autarchic wastewater treatment plant (WWTP) in several countries. On a closer look, this statement refers almost always only on the electricity consumption, the heat demand mostly was ignored. A survey concerning energy efficiency on wastewater treatment plants in North-West- Europe shows, that the so-called energy self-sufficient sewage treatment plant is still an issue for the next years. The more detailed analysis of already conducted energy audits and evaluated data from operational diaries shows that in many cases, especially for plants with anaerobic digestion, the own power production is regarded as the single criterion for energy self-sufficiency. In this study, therefore, further criteria such as heat demand/heat production and degradation rates were used for a comparison at a national level. [less ▲]

BACKGROUND: Emotion reactivity is defined as the extent to which an individual experiences emotions in response to a wide array of stimuli, intensely, and for a prolonged period. This construct is a key psychological factor in the development and maintenance of psychopathological disorders. The aim of the current study was to develop and validate a French version of the Emotion Reactivity Scale (ERS), which gauges three aspects of emotion reactivity: (1) emotional sensitivity, (2) emotional intensity, and (3) emotional persistence. METHOD: The French ERS and both concurrent and divergent validated scales were administered to 258 participants from the community. RESULTS: Confirmatory factor analyses revealed good fit indices for: (1) a single-factor model, (2) a three-factor model, and (3) a hierarchical three-factor solution with a single-factor solution as a second-order latent variable for a generic construct of emotion reactivity. The French version of the Emotion Reactivity Scale also exhibits acceptable internal scale score reliability (total scale and subscales). Eventually, meaningful relationships were found between factors of emotion reactivity and depression, distinct aspects of impulsive behaviors, and maladaptive emotion regulation strategies. CONCLUSION: Findings of the confirmatory factor analyses are consistent with previous studies suggesting that the ERS is mainly captured by a single major construct of emotion reactivity. [less ▲]
