title: The influence of leaders organizational citizenship behaviors and counterproductive work behaviors on employee wellbeing: A multilevel investigation

authors: Roche, Maree A.

abstract: Leader’s organizational citizenship behaviors (OCBs) have been found to directly and indirectly enhance group OCBs, while counter productive work behaviors (CWBs) can have an effect on employee stress and related problems. While previous research has considered these separately, Moral Licensing Theory suggests that those leaders who engage in positive behaviors can feel that they are then able to subsequently engage in negative behaviors. We test the influence of 134 leaders’ on 306 followers job burnout, and find leaders’ self-rated organizational citizenship behaviors (OCBs) were negatively related to follower-rated leaders’ counterproductive work behaviors (CWBs) and followers’ job burnout, and leaders’ CWB were positively related. We also tested and found that CWB interacted with OCBs, which showed that leaders’ who highly engage in positive behaviors still have a positive influence on their followers even when they engage in negative behaviors. Overall, we find empirical support for moral licensing, finding that leaders’ positive behaviors are still most important.

title: Petrogenesis of Cenozoic, alkalic volcanic lineages at Mount Morning, West Antarctica and their entrained lithospheric mantle xenoliths: Lithospheric versus asthenospheric mantle sources

authors: Martin, Adam P.

subjects: volcanic lineage

abstract: Two volcanic lineages are identified at Mount Morning, a Cenozoic to recent, eruptive centre in the Ross Sea, West Antarctica, which is part of the McMurdo Volcanic Group. Both the older (at least 18.7–11.4 Ma), mildly alkalic, nepheline- or quartz-normative Mason Spur Lineage, and the younger (at least 6–0.02 Ma), nepheline normative, strongly alkalic Riviera Ridge Lineage evolved by fractional crystallization from nominally anhydrous (<0.5 wt% H2O) parental magmas. Both lineages are analogous to other, relatively anhydrous lineages in the McMurdo Volcanic Group and distinctly different from those in which kaersutite is present on the liquid line of descent. Sub-continental lithospheric mantle (SCLM) xenoliths entrained in Riviera Ridge Lineage rocks show trace element and isotopic Sr–Nd–Pb variation that is consistent with four-component mixing whereby depleted mantle has been refertilised by enriched, HIMU-like and Nb-enriched (carbonatite) components. Refertilization may have occurred c. 530–490 Ma ago when fluids derived from subduction associated with Gondwanaland amalgamation infiltrated the SCLM. Similar trace element and isotope variation (Sr–Nd–Pb) in Mount Morning basaltic rocks and entrained xenoliths suggests that the source for the basaltic magmas lies (at least in part) in the lithospheric mantle. It has long been recognized that Cenozoic volcanic rocks in Antarctica (Victoria Land – including Mount Morning – and Marie Byrd Land), Zealandia and eastern Australia share common chemical and isotopic source characteristics and they have been argued to collectively constitute a single diffuse alkaline magmatic province (DAMP). Source characteristic similarities suggest DAMP volcanic rocks inherit at least some of their trace element and isotopic characteristics from the lithospheric mantle. Super-chondritic Nb/Ta values measured in some SCLM xenoliths and volcanic rocks at Mount Morning, and in volcanic rocks across the DAMP, can be explained by addition of ⩽5 wt% carbonatite to the source. The DAMP SCLM is a significant Nb reservoir that offers an explanation for the Nb paradox.
