Does environmentally specific transformational leadership promote team pro-environmental behaviors? If so, why and when? Using the cognitive-affective processing system framework, we explore the idea that environmentally specific transformational leadership facilitates team pro-environmental behaviors via team pro-environmental goal clarity and team pro-environmental harmonious passion separately and that such indirect relationships are stronger when the team power distance is high. We used three waves of data from 113 teams in six Chinese manufacturing organizations to test our theoretical predictions. The results of regression analyses show that environmentally specific transformational leadership is positively related to team pro-environmental behaviors; this relationship is parallel mediated by team pro-environmental goal clarity and team pro-environmental harmonious passion. Furthermore, the team power distance strengthens the above parallel mediation effects such that in teams with high levels of power distance, environmentally specific transformational leadership strongly provokes team members’ pro-environmental goal clarity, pro-environmental harmonious passion, and subsequent pro-environmental behaviors. These findings suggest that environmentally specific transformational leadership is an effective approach for organizations to improve their teams’ pro-environmental behaviors, particularly in the context of strong power distance.

Owing to its low-cost and satisfactory luminescent-emission performance in warm white light-emitting diodes (w-LEDs), the non-rare-earth Mn4+-activated red phosphor has become a promising competitor of commercial rare-earth doped phosphor. In this study, a series of novel red-light emitting phosphors based on Ca2YSbO6:Mn4+ have been developed successfully by a conventional solid-state reaction. The structural and luminescent properties of these phosphors are systematically investigated. The as-prepared Ca2YSbO6:Mn4+ product exhibits a broad excitation band ranging from 250 to 600 nm and an abnormal intense deep-red emission centered at 680 nm with a full width at half maximum (FWHM) of ∼46 nm. The optimal Mn4+ doping concentration is about 0.3 mol%, and the concentration quenching mechanism is determined to be a dipole-dipole interaction. Impressively, the Ca2YSbO6:0.003Mn4+ phosphor shows an outstanding quantum efficiency of 62.6% and an excellent thermal stability. In addition, the effect of Li+, Mg2+, Na+ and K+ dopants on the luminescent properties of Mn4+-doped Ca2YSbO6 phosphors is elucidated. Furthermore, by employing the as-prepared Ca2YSbO6:Mn4+ as a red component, a warm w-LED with high color rendering index (Ra = 87.5) and low correlated color temperature (CCT = 3255 K) can be acquired. It is believed that the present phosphor has a potential application as a supplement of the red component for warm w-LEDs.

The utility of leader humility expressing behavior has been examined by several studies across multiple levels. However, our knowledge about why leaders express humility continues to be sparse. Drawing on rational choice theory, this paper proposes a model examining whether followers’ capability triggers leader’s humility expressing behavior and how followers’ interpretations of it influence its effectiveness. Results from 278 leader-follower dyads from a time-lagged research design showed that followers’ capability as perceived by the leader is positively related to leader-expressed humility and, in turn, this behavior would conditionally enhance follower trust, that is, followers will trust the humble leader less when they attribute leader’s expressed humility more to serving impression management motives. Several theoretical and practical implications of this observation are discussed in this study.
