social value orientation and climate strength as moderators of the impact of work group cooperative climate on affective commitment
Journal of Management Studies, 2012Co-Authors: Sandy Bogaert, Christophe Boone, Arjen Van WitteloostuijnAbstract:We investigate the moderating role of an individual's social value orientation (which refers to self- versus other-regarding preferences) and of climate strength (which refers to the extent of agreement among group members on group norms and values) on the relationship between work group cooperative climate and affective commitment among professional employees. We develop two plausible but opposite hypotheses on the moderation effect of social value orientation, one based on the behavioural assimilation assumption and the other on goal transformation theory. We argue that the work group's climate strength is an important contingency factor that affects which of both contradictory predictions holds. In a sample of 209 academic employees of a Belgian university, we find support for our arguments. Specifically, a cooperative climate enhances the affective commitment of employees with a prosocial value orientation (as predicted by the behavioural assimilation argument) but only when there is strong consensus among group members about the group's climate (high climate strength). Conversely, for those whose social value orientation is towards the self rather than others, a cooperative climate enhances affective commitment (consistent with goal transformation theory), especially when the climate is not agreed upon (low climate strength). These findings underscore recent claims that the predictive power of different theories in organizational behaviour depends on an individual's motives and values. We discuss the implications of our findings for the management of work groups consisting of employees with different social value orientations.

very high cycle fatigue behavior of ti 6al 4v manufactured by selective laser melting effect of build orientation
International Journal of Fatigue, 2020Co-Authors: Guian Qian, Davide Salvatore Paolino, Andrea Tridello, Filippo Berto, Youshi HongAbstract:Abstract The effect of building orientation on the very-high-cycle fatigue (VHCF) response of Ti-6Al-4V specimens produced through selective laser melting (SLM) process with three different building orientations (0°, 45° and 90°) has been experimentally assessed. The fatigue performance decreases with different building orientations from 0° to 90°. The fatigue crack origin has been found to be always an internal defect both at high-cycle fatigue and VHCF regime independent of building orientations. Size of defects induced fatigue failures and the stress intensity factor range decrease with the number of cycles to failure. By considering the VHCF strength at 109 cycles, the median value decreases from 217 MPa (0°) to 201 MPa (45°) and finally to 155 MPa (90°), with a 40% reduction from 0° to 90°. The building orientation significantly influences both the defect size and the resulting VHCF response.

work values underlying protean and boundaryless career orientations
Career Development International, 2017Co-Authors: Marc Abessolo, Andreas Hirschi, Jerome RossierAbstract:Purpose This study aimed to investigate the relation among work values and protean and boundaryless career orientations. Design/methodology/approach A sample of 238 employees aged 16 to 65 years from the French-speaking region of Switzerland completed two different work values scales as well as protean and boundaryless career attitudes scales. To assess the relationships among these constructs, correlations, multiple regression, and exploratory factorial analysis techniques were used. Findings Results suggested that protean and boundaryless career orientations were significantly positively related to intrinsic, social, and status work values. A boundaryless- organizational mobility orientation was significantly negatively associated with extrinsic/material work values. Research limitations/implications Results have important implications for understanding which work values are typically endorsed by people with a protean or a boundaryless career orientation. Originality/value The present study contributes ...

effects of substrate crystallographic orientations on crystal growth and microstructure development in laser surface melted superalloy single crystals mathematical modeling of single crystal growth in a melt pool part ii
Acta Materialia, 2005Co-Authors: J N DupontAbstract:Abstract The mathematical model developed for single-crystalline solidification in laser surface melting (LSM) described in Part I [Acta Mater 2004;52:4833–4847] was used to compute the dendrite growth pattern and velocity distribution in the 3D melt pool for various substrate orientations. LSM experiments with single-crystal nickel-base superalloys were conducted for different orientations to verify the computational results. Results show that the substrate orientation has a predominant effect on crystal growth pattern, and simultaneously influences the magnitude and distribution of dendrite growth velocity in the melt pool. The selected 〈1 0 0〉 growth variants and the number of the chosen growth variants are dependent on the substrate orientation. The maximum velocity ratio (dendrite growth velocity over the beam velocity, V/Vb) in the melt pool is a function of melt-pool geometrical parameters and the substrate orientation. The largest maximum velocity-ratio among the symmetric orientations is 1.414 for the (0 0 1)/[1 1 0] and ( 0 1 1 ) / [ 0 1 1 ¯ ] orientations, while that value for asymmetric orientations is 1.732 for the ( 0 1 1 ) / [ 1 1 1 ¯ ] orientation. Good agreement was obtained between the predicted and experimentally observed microstructures. The results are discussed with the susceptibility to stray grain formation as a function of substrate orientations and melt-pool geometrical parameters. These findings have some important implications for single-crystal surface processing.
