How employees respond to personal offense: The effects of blame attribution, victim status, and offender status on revenge and reconciliation in the workplace.

This study investigated the relationships between blame, victim and offender status, and the pursuit of revenge or reconciliation after a personal offense. Results from a sample of 141 government agency employees showed that blame is positively related to revenge and negatively related to reconciliation. In addition, victim–offender relative status moderated the relation between blame and revenge such that victims who blamed sought revenge more often when the offender's status was lower than their own. The victims' own absolute hierarchical status also moderated this relation such that lower, not higher, status employees who blamed sought revenge more often.

Determination of flow stress properties of machinable materials with help of simple compression and orthogonal machining test

This paper describes a possible method for predicting values of orthogonal metal cutting properties such as shear angle, cutting force etc., on a basis of the well known Hollomon equation, using a simple compression test in order to avoid any cutting experiments. There are two possibilities: the flow stress properties can be obtained from an independent material test; or by measuring the active and passive cutting forces from the orthogonal machining test itself. This paper is concerned with a material flow stress equation, including the effects of strain (ε), strain rate ( ) and temperature (T), which is one of the five equations that have to be solved in simulation analysis with the finite element method. In finding a solution for those five equations, it is necessary to dispose of flow stress properties by rearrangement of the Hollomon equation and so making it usable for cutting process investigation. The rearrangement is described in this paper.     

Soil Degradation of Parthenin—Does it Contradict the Role of Allelopathy in the Invasive Weed Parthenium hysterophorus L.?

The invasive success of Parthenium hysterophorus L. is thought to be partially attributable to allelopathy mediated by the plant metabolite parthenin. To assess the ecological significance of parthenin release from plant material, its persistence and phytotoxicity in soil was studied. Results show parthenin is rapidly degraded with an average DT ₅₀ of 59 h under standard experimental conditions. Degradation was delayed in sterilized soils, at lower soil moisture, and higher parthenin concentrations. Higher temperatures, higher CEC_pot/clay content of soils, soil preconditioning with parthenin, and P. hysterophorus infestation accelerated degradation. Physico-chemical and biological processes are, therefore, expected to govern the fate of parthenin in soil. Parthenin exhibited low soil phytotoxicity and did not accumulate over time. Along with the indicated reduction in bioavailability and development of hormetic effects, results suggest that for parthenin to have detrimental allelopathic effects, it requires high P. hysterophorus densities that result in high soil levels of parthenin and soil conditions that favor the persistence of parthenin. In light of this, the ecological significance of parthenin is discussed.     

Airflow rates by combined natural ventilation with opposing wind—unambiguous solutions for practical use

Analysis of possible airflow rates by combined natural ventilation with opposing wind in rooms with two openings shows multiple solutions, instability and hysteresis. In this paper, it is analysed to what extent these phenomena should be considered under practical conditions. The analysis shows that unambiguous solutions can be obtained if difference between indoor and outdoor temperature is known at start, i.e. when heat sources are switched on and ventilation openings are opened. Discontinuities in airflow rates occur under certain specific conditions.
