Microstructures and tensile properties of 304 steel with dual nanocrystalline and microcrystalline austenite content prepared by aluminothermic reaction casting

The microstructures of 304 stainless steels with different amounts of nanocrystalline and microcrystalline austenite prepared by an aluminothermic reaction casting, without and with annealing at 1073?K for 8?h, have been investigated by X-ray diffraction, an electron probe micro-analyser, a transmission electron microscope and a scanning electron microscope. The steels, both without and with annealing, consisted of different dual nanocrystalline and microcrystalline austenite combinations and a little nanocrystalline δ ferrite, while the average grain size of the nanocrystalline austenite increased from 19 to 26?nm and volume fraction of the microcrystalline austenite increased from 17 to 30% after annealing. The tensile strength of the steel was dramatically increased from 500 to 1000?MPa and the tensile elongation ratio increased from 8 to 12% after annealing. However, the tensile strength was decreased to 600?MPa and the tensile elongation ratio increased from 12 to 22% after an annealing at 1273?K. The combination of dual nanocrystalline and microcrystalline austenite obtained after the annealing at 1073?K results in the best tensile properties.     

Wentzel–Kramers–Brillouin solution of cut-off frequency for horizontal shear (SH) waves in various inhomogeneous thin films

The Wentzel–Kramers–Brillouin method is employed to study the cut-off frequencies of the horizontal shear waves in a freestanding functionally graded piezoelectric–piezomagnetic material film with the electrically and magnetically open boundary conditions. An analytical solution, which could be used in analyzing the problems of various functionally graded materials, is proven to have high precision by analytical analysis and a numerical example. The results reveal that the set of cut-off frequencies is a series of approximate arithmetic progressions. A theoretical foundation based on the relationship between the cut-off frequencies and the materials’ gradient property is established for nondestructive evaluation.

Mentoring in China: Enhanced Understanding and Association with Occupational Stress

Purpose  

Given the increased usage of mentoring programs in multi-cultural settings, including the Chinese workplace, the present study examined Chinese employees’ understanding of mentoring relationships and whether mentoring played a role in their occupational stress process.     

Supervisors' upward exchange relationships and subordinate outcomes: testing the multilevel mediation role of empowerment

This study empirically examined the proposition that supervisors' exchange relationships with their own supervisors (i.e., leader-leader exchange, or LLX) are related to their subordinates' work-related outcomes through 3 mechanisms: (a) leaders modeling their LLX to develop and maintain their exchange relationships with their subordinates (i.e., leader-member exchange, or LMX), (b) motivating the team and its members, captured by team and individual empowerment, and (c) facilitating the relationships between LMX and individual outcomes. Analyses of multisource and lagged data from 104 team supervisors and 577 subordinates showed that LMX mediated the positive relationship of LLX on subordinates' individual empowerment. Furthermore, team empowerment and individual empowerment sequentially mediated the positive relationships between LLX and subordinates' job satisfaction and job performance. The authors also found that the indirect relationships of LMX with job satisfaction and job performance via individual empowerment were stronger when LLX was higher. Theoretical and practical implications of these findings are discussed.

The relationship between identity, intimacy, and midlife well-being: findings from the Rochester Adult Longitudinal Study

The present study used longitudinal data on 182 adults between the ages of 20 and 54 (104 men, 78 women) from the Rochester Adult Longitudinal Study (RALS), assessed on four occasions, to test the hypothesis that identity and intimacy during the course of early and middle adulthood predict well-being at midlife. A cross-lagged panel model was estimated yielding the following findings: (a) Scores on both scales during the college years predicted midlife satisfaction-intimacy directly, and identity through the course of development from ages 20 to 54; moreover, identity in midlife, but not intimacy, was significantly linked with well-being at this same point in time; and (b) identity and intimacy unexpectedly did not predict one another over time, having been controlled for factor stability in identity and intimacy over time. The findings are discussed in terms of Erikson's psychosocial theory of development and the developmental moments and historical cohorts that characterize the present sample.     

Do the effects of a family intervention on alcohol and drug use vary by nativity status?

To examine whether the intervention effects of Familias Unidas, compared to community practice, on Hispanic adolescent alcohol and drug use varies by nativity status (i.e., U.S.-born and foreign-born). A total of 213 eighth grade Hispanic adolescents with behavior problems and their primary caregivers were assigned randomly to one of two conditions: Familias Unidas or Community Control. Participants were assessed at baseline and at 6, 18, and 30 months post baseline. Results showed that, the effects of Familias Unidas on alcohol use was moderated by nativity status. Specifically, Familias Unidas was efficacious in preventing/reducing alcohol use for U.S.-born youth, but not foreign-born. No moderating effects were found for drug use. These findings suggest that prevention interventions may be more efficacious in preventing/reducing alcohol use among certain Hispanic adolescent subgroups.
