OBJECTIVES: The fact that motorcycle users tend to be more vulnerable to injuries than those using other motorized vehicles may act synergistically with the complexity of conflicting movements between vehicles and motorcycles to increase injury severity in a junction-type accident. A junction-type collision tends to be more severe than a non-junction case due to the fact that some of the injurious crashes such as angle-collision commonly occur. Existing studies have applied several statistical modeling techniques to examine influential factors on the occurrences of different crashes among motorized vehicles but surprisingly very little has empirically explored whether a particular crash type, resulting from a junction-type accident, is more injurious to motorcyclists. This article attempts to investigate whether a particular collision is more deadly to motorcyclists conditioned on crash occurrence at T-junctions in the U.K., while controlling for environment, vehicle, and demographic factors. METHODS: The statistical modeling technique employed is the ordered probit models using the data extracted from the STATS19 accident injury database (1999-2004). RESULTS: The modeling found determinants of injury severity among motorcyclists at T-junctions in the U.K. For example, an approach-turn/head-on collision is much more injurious to motorcyclists; and, those riding in early morning (i.e., 0000-0659) are more likely to be severely injured. CONCLUSIONS: This study offers a guideline for future research, as well as insight into potential prevention strategies that might help moderate motorcyclist injuries. 相似文献

In this study, we draw from the conservation of resources theory and the narcissism literature to examine why and when narcissistic leaders develop and maintain differentiated social relationships with followers in a group setting, therefore demotivating follower voice. Using data from 457 employees and their 95 supervisors working at a large Chinese consulting company, we tested and found support for our hypotheses that leader narcissism had a negative direct effect on employee voice, as well as a negative indirect effect on voice via group-level leader–member exchange (LMX) differentiation. Our findings further showed that leaders' upward exchange, leader–leader exchange (LLX), with their own supervisor moderated the negative indirect effect of narcissism on voice such that this negative indirect effect was stronger in the presence of low leader LLX but turned nonsignificant in the presence of high leader LLX. Theoretical and practical implications of our research are discussed. Limitations and directions for future research are also offered. 相似文献

Transition-metal coordination polymers [M(ndc)(bpy)·(H2O)m]·xH2O (where M = Co(II), Ni(II), Cu(II) and Zn(II), ndc = 1,4-naphthalenedicarboxylate, bpy = 4,4′-bipyridine; m = 0 or 1; x = 1 or 2) were prepared by reacting the ligands and metal ions at room temperature with the aid of microwave irradiation and sonication methods. The structure of the coordination polymers was assigned based on elemental analysis, FT-IR and electronic spectral studies, thermal analysis, scanning electron microscope and X-ray powder diffraction. Thermogravimetric analysis was also used to follow up the possible thermal decomposition steps and to calculate the thermodynamic parameters of the nano-sized metal complexes. The kinetic parameters were calculated making use of the Coats–Redfern and Horowitz–Metzger equations. All obtained results of the different technics used in our study stated the ability to synthesis the metal coordination polymers of our interest using both microwave irradiation and sonication methods. 相似文献
