Prevalence and forms of bullying among business professionals: A comparison of two different strategies for measuring bullying

The aim of this study was to analyse the prevalence and forms of workplace bullying among business professionals holding predominantly managerial or expert positions. A cross-sectional survey study was conducted among Finnish professionals with a university degree in business studies. In the study two different strategies for measuring bullying were used and compared. When provided a definition of bullying, 8.8% of the respondents reported that they had at least occasionally been bullied during the past 12 months. However, when using a slightly modified version of the Negative Acts Questionnaire (Einarsen & Hoel, 2001), containing a list of 32 predefined negative and potentially harassing acts, as many as 24.1% of the respondents reported that they had been subjected to at least one of the negative acts on a weekly basis. The respondents had experienced predominantly work-related negative acts, e.g., that their opinions and views were ignored, that they were given unreasonable deadlines, or that information was withheld. Although the prevalence rates reported with the two strategies varied considerably, there was still consistency between the two strategies in the sense that those who had classified themselves as bullied also reported higher exposure rates to almost all of the negative acts included.     

Personalistic concepts in action: The case of Adolf Hitler

Grounded in his personalistic worldview, William Stern regarded persons as inherently valuable beings who use values to conduct their lives. One might wonder if such a value-laden and idealistic approach can be applied to the case of Adolf Hitler, who clearly was a very destructive and disharmonious figure. In order to deal with this challenging question we will refer to three personalistic principles, namely convergence, introception, and unitas multiplex. As our analysis shows, all three principles can be exemplified in the case of Hitler if a neutralized version of each principle is used. By the demonstration of “iron will” he strived for coherence and unity, and was tremendously successful in managing that his followers introcepted the Nazi ideals. The convergence principle also applies to Hitler since there was unique conjunction of his traits with influences of his era.     

Peripheral and foveal segmentation of angle textures

Studies of the effects of retinal eccentricity on the visual segmentation of textures are presented. The textures used in these studies were composed of angle elements. These were presented tachistoscopically to college students in three different experiments. Results showed that there were different relationships between segmentation performance and eccentricity, depending on the width of the angles used in the background and target texture. One major difference was that peak performance was found in the fovea in some conditions, and in peripheral areas in other conditions. Performance in the fovea and the periphery seemed to be determined by qualitatively different features. It was assumed that an appropriate explanation is that the system-internal representation of a specific stimulus within the early visual system differs as a function of the retinal location at which it is projected. Thus, the critical features discriminating between target and background texture have to be sought in the system-internal representation of the stimulus instead of in the stimulus itself. The data show that a relatively exact system-internal representation of the stimulus is present in the fovea, where performance is determined by angle width. In the periphery, in contrast, angles seem to be represented as “blobs,” and performance is determined by the orientation of the blobs’ main axes.     

Zum Zusammenhang zwischen Projektionsoperatoren und Eigenschaften

Der nichtdistributive, orthokomplementäre Verband der Projektionsoperatoren in der Quantenmechanik hat Anlaß zu mancherlei Interpretationen gegeben, so z. B. als eine von der klassischen Logik abweichende Quantenlogik, oder man deutete die Projektionsoperatoren als Eigenschaften von Mikroobjekten. Wir glauben, mit dieser Arbeit ein wesentliches Argument für die letztere Interpretation liefern zu können:Es ist nämlich möglich, in der Menge der Eigenschaftsbegriffe eine Ordnungs-relation einzuführen. Mit dieser Ordnungsrelation bildet einen nichtdistributiven, orthokomplementären Verband. D.h. bei einer solchen Interpretation werden keinerlei Veränderungen — weder im Verband der Aussagen noch im Verband der Eigenschaftsbegriffe — durch die Entdeckung der Quantenmechanik notwendig.     

New illusions of sliding motion in depth

Apparent sliding motion in the so-called Ouchi illusion has been attributed to the global integration of local motion vectors arising from the aperture effect (Fermüller et al, 2000 Vision Research 40 77- 96; Mather, 2000 Perception 29 721-727). In a number of variants of the Ouchi illusion, we here demonstrate that sliding motion will also arise without a directional motion bias from local elements. Specifically, we show that in a disk-annulus pattern made from wiggly lines, sliding motion occurs although the local orientations within the disk and annulus are the same. We then argue that in an array of square-shaped checks, sliding motion originates from the interaction between the explicit orientation of the checks and the implicit orientation of the invisible diagonals. Finally, we demonstrate that a central array of filled black circles surrounded by a grey edge appears to slide relative to a surround of empty circles. We tentatively account for sliding motion in this figure by differences in speed signals, figure-ground segregation and apparent depth due to contrast polarity, edge blur, demarcation by a frame, and difference in shape.     

Brightness enhancement seen through a tube

We report a fascinating phenomenon that emerges when a surface is viewed through a tube held close to one eye, with the other eye open. The disk-shaped area seen through the tube looks strikingly brighter and, when viewed on a textured background, also of higher spatial contrast than the same surface area viewed without a tube. The effect is reminiscent of a spotlight illuminating the area under consideration. We call this the 'tube effect'. The tube effect is one of the strongest contrast illusions known to us. It requires a matching luminance that is twice as high as the reference luminance seen through the tube. Brightness ratings increase linearly with the log of the background luminance. The effect (i) produces a dark afterimage, (ii) reverses in polarity with low ambient illumination, (iii) assumes the complementary colour of the illuminant, and (iv) persists with fully dilated pupils. Potential explanations include simultaneous contrast (due to the penumbra and dark inner walls of the tube) and veiling of the surround (due to local adaptation and a lower gain factor).     

Risk factors of workplace bullying for men and women: The role of the psychosocial and physical work environment

Workplace bullying has been shown to be a severe social stressor at work, resulting in high costs both for the individuals and organizations concerned. The aim of this study is to analyze risk factors in a large, nationally representative sample of Finnish employees (n = 4,392). The study makes three important contributions to the existing literature on workplace bullying: first, it demonstrates the role of the physical work environment alongside the psychosocial work environment – employees with a poor physical work environment are more likely than others to report having been subjected to or having observed bullying. Second, contrary to common assumptions, the results suggest that performance‐based pay is associated with a lower, rather than higher risk of bullying. Third, the findings suggest that there are gender differences in risk factors, thereby constituting a call for more studies on the role of gender when identifying risk factors. Increased knowledge of risk factors is important as it enables us to take more effective measures to decrease the risk of workplace bullying.
