Building effective organizations: transformational leadership, collectivist orientation, work-related attitudes and withdrawal behaviours in three emerging economies

Abstract: Previous cross-cultural research on transformational leadership has focused mainly on replicating the augmentation effects of transformational leadership over transactional leadership on followers' attitudes and behaviours Relatively few studies have systematically examined cultural impacts in moderating the influence of transformational leadership on work-related outcomes taking a cross-cultural perspective Using a field survey of 577 employees from banking and financial sectors in three emerging economies, namely: China, India and Kenya, we examined the moderating effect of collectivism on the relationships between transformational leadership, work-related attitudes and perceptions of withdrawal behaviours Our results found support for the moderating effect of collectivism on the relationship between transformational leadership and work-related outcomes, such as facets of job satisfaction, organizational commitment and perceptions of organizational withdrawal behaviours In addition, our results lend

Thin single crystal perovskite solar cells to harvest below-bandgap light absorption

Abstract: The efficiency of perovskite solar cells has surged in the past few years, while the bandgaps of current perovskite materials for record efficiencies are much larger than the optimal value, which makes the efficiency far lower than the Shockley-Queisser efficiency limit. Here we show that utilizing the below-bandgap absorption of perovskite single crystals can narrow down their effective optical bandgap without changing the composition. Thin methylammonium lead triiodide single crystals with tuned thickness of tens of micrometers are directly grown on hole-transport-layer covered substrates by a hydrophobic interface confined lateral crystal growth method. The spectral response of the methylammonium lead triiodide single crystal solar cells is extended to 820 nm, 20 nm broader than the corresponding polycrystalline thin-film solar cells. The open-circuit voltage and fill factor are not sacrificed, resulting in an efficiency of 17.8% for single crystal perovskite solar cells.

Marital Happiness, Marital Duration, and the U-Shaped Curve: Evidence from a Five-Wave Panel Study

Abstract: Previous research suggests a U-shaped pattern of marital happiness over the life course, with happiness declining in the early years of marriage and rising in the later years. Mostprior studies have been limited by the use of cross-sectional data or nonprobability samples. In contrast, the present study is based on data from a national, 1 7-year, 5wave panel sample. Using cross-sectional data from the first wave, we replicate the Ushaped relationship between marital happiness and marital duration. In an analysis based on a fixed-effects pooled time-series model with multiple-wave panel data, we find declines in marital happiness at all marital durations and no supportfor an upturn in marital happiness in the later years. The relationship between marital happiness and marital duration is slightly curvilinear, with the steepest declines in marital happiness occurring during the earliest and latest years of marriage. When other lifecourse variables are controlled, a significant negative effect of marital duration on marital happiness remains. For most marriage cohorts, marital happiness declined more in the 1980s than in the 1990s, suggesting a period effect. This study provides evidence that the U-shaped pattern of marital happiness over the life course is an artifact of cross-sectional research and is not typical of U.S. marriages.
