TL;DR: It is found that comparatively expensive mitigation measures reduce large mammal road-kill much more than inexpensive measures, and that inexpensive measures such as reflectors should not be used until and unless their effectiveness is tested using a high-quality experimental approach.
Abstract: Road traffic kills hundreds of millions of animals every year, posing a critical threat to the populations of many species. To address this problem there are more than forty types of road mitigation measures available that aim to reduce wildlife mortality on roads (road-kill). For road planners, deciding on what mitigation method to use has been problematic because there is little good information about the relative effectiveness of these measures in reducing road-kill, and the costs of these measures vary greatly. We conducted a meta-analysis using data from 50 studies that quantified the relationship between road-kill and a mitigation measure designed to reduce road-kill. Overall, mitigation measures reduce road-kill by 40% compared to controls. Fences, with or without crossing structures, reduce road-kill by 54%. We found no detectable effect on road-kill of crossing structures without fencing. We found that comparatively expensive mitigation measures reduce large mammal road-kill much more than inexpensive measures. For example, the combination of fencing and crossing structures led to an 83% reduction in road-kill of large mammals, compared to a 57% reduction for animal detection systems, and only a 1% for wildlife reflectors. We suggest that inexpensive measures such as reflectors should not be used until and unless their effectiveness is tested using a high-quality experimental approach. Our meta-analysis also highlights the fact that there are insufficient data to answer many of the most pressing questions that road planners ask about the effectiveness of road mitigation measures, such as whether other less common mitigation measures (e.g., measures to reduce traffic volume and/or speed) reduce road mortality, or to what extent the attributes of crossing structures and fences influence their effectiveness. To improve evaluations of mitigation effectiveness, studies should incorporate data collection before the mitigation is applied, and we recommend a minimum study duration of four years for Before-After, and a minimum of either four years or four sites for Before-After-Control-Impact designs.

TL;DR: The results of these experiments indicate that the sex difference in the social play of prepubescent rats is dependent on the neonatal exposure to testosterone or to its 5α-reduced metabolite, dihydrotestosterone.

TL;DR: Results suggest a major role for Golgi cells in coordinating cerebellar sensorimotor integration during oscillatory interactions, and show that electrical transmission of the spike afterhyperpolarization is the essential component for oscillatory population synchronization.

TL;DR: In this article, the authors identify the intervening processes inherent in the relationship between transformational leadership and team performance and creativity and provide evidence for a sequential mediation model where leadership influences team outcomes through overall team communication and trust in teammates.
Abstract: Considerable theoretical and empirical work has identified a relationship between transformational leadership and team performance and creativity. The mechanisms underlying this link, however, are not well understood. To identify the intervening processes inherent in this relationship, we experimentally manipulated the leadership style assigned to 44 teams taking part in a resource-maximization task. Teams were exposed either to a leader using inspirational motivation, intellectual stimulation, or a control condition. Our findings reveal important differences between leadership styles in communication and team outcomes (objective task performance and creativity). These results suggest that different dimensions of transformational leadership should be emphasized depending on the outcome sought. In addition, our results provide evidence for a sequential mediation model where leadership influences team outcomes through overall team communication and trust in teammates. This study suggests mechanisms by which transformational leaders may impact team outcomes, which has implications for team building and leadership training.

TL;DR: A wavelength-division-multiplexed-based passive-optical-network (PON) architecture that allows for incremental upgrade from single-channel time-division multiple-access PONs in order to provide higher bandwidth in the access network is discussed.
Abstract: We discuss a wavelength-division-multiplexed-based passive-optical-network (PON) architecture that allows for incremental upgrade from single-channel time-division multiple-access PONs in order to provide higher bandwidth in the access network. Various dynamic-wavelength and bandwidth-allocation algorithms (DWBAs) for wave-division multiplexed PON are presented; they exploit both interchannel and intrachannel statistical multiplexing in order to achieve better performance, especially when the load on various channels is not symmetric. Three variants of the DWBA are presented, and their performance is compared. While the first variant incurs larger idle times (and, hence, poor performance), the other two algorithms achieve better but different performance with critical dissimilarities. Our analysis also focuses on the fair assignment of excessive bandwidth in the upstream direction to highly loaded optical network units. We compare the performance of DWBA to another algorithm that relies on static-channel allocation. Furthermore, a study is presented wherein the number of wavelengths increases, and a comparison with interleaved polling with adaptive cycle time is shown. We use extensive simulations throughout this paper
