Safety of Vulnerable Road Users (VRU's) in Light-Rail Transit (LRT) Environment
<p>Light-rail transit (LRT), which includes modern streetcars, trolleys, and heritage trolleys, is one of the fastest growing modes of public transportation in the United States. To reduce the cost and complexity of construction, most LRT systems have their tracks placed on city streets, in medians, or in separate at-grade rights-of-way with at-grade crossings. Operating light-rail vehicles (LRVs) along these alignments introduces new conflicts and increases the risk of collisions with vulnerable road users (VRUs) including pedestrians, bicyclists, and electric scooter riders.<br> This study has two main objectives: (1) to review and evaluate the existing body of knowledge and the state of practice regarding safety of VRUs in LRT environments; and (2) to synthesize this information and package the results in a “Best Practices Resource Guide” and a companion “PowerPoint Presentation” for use in improving the safety of VRUs in existing LRT systems and advancing the professional capacity of transit workforce. Metropolitan Planning Organizations and State DOTs should also benefit from this resource information in the planning and design of new LRT systems.<br> This report presents a wide range of physical, educational, and enforcement treatments for improving the safety of VRUs in LRT environments. The selection of a particular treatment for use at an LRT grade crossing or station should be based on an engineering study whose scope and complexity depend on local conditions. Factors that should be considered during device selection include 1) pedestrian‐LRV collision experience, 2) pedestrian volumes and peak flow rates, 3) train speeds, frequency of trains, number of tracks, and railroad traffic patterns, 4) sight distances available to pedestrians and LRV operators approaching the crossing, and 5) skew angle, if any, of the crossing relative to the LRT tracks.</p>
Data for: Macroevolution in axial morphospace: Innovations accompanying the transition to marine environments in elapid snakes
<p><span>Sea snakes in the <em>Hydrophis</em>-<em>Microcephalophis</em> clade (Elapidae) show exceptional body shape variation along a continuum from similar forebody and hindbody girths, to dramatically reduced girths of the forebody relative to hindbody. The latter is associated with specialisations on burrowing prey. This variation underpins high sympatric diversity and species richness and is not shared by other marine (or terrestrial) snakes. Here, we examined a hypothesis that macroevolutionary changes in axial development contribute to the propensity, at clade level, for body shape change. We quantified variation in the number and size of vertebrae in two body regions (pre- and post-apex of the heart) for ~94 terrestrial and marine elapids. We found <em>Hydrophis</em>-<em>Microcephalophis</em> exhibit increased rates of vertebral evolution in the pre- versus post-apex regions compared to all other Australasian elapids. Unlike other marine and terrestrial elapids, axial elongation in <em>Hydrophis</em>-<em>Microcephalophis</em> occurs via the preferential addition of vertebrae pre heart apex, which is the region that undergoes concomitant shifts in vertebral number and size during transitions along the relative fore- to hindbody girth axis. We suggest that this macroevolutionary developmental change has potentially acted as a key innovation in <em>Hydrophis</em>-<em>Microcephalophis</em> by facilitating novel (especially burrowing) prey specialisations that are not shared with other marine snakes.</span></p>
IDE Interactions of Novices Transitioning Between Programming Environments
<p>Novices in introductory programming courses typically learn the fundamentals of programming using one of a wide of programming<br> environments. These vary greatly in terms of the mechanisms they employ to assist programmers, including their approaches to compilation and error message presentation. It is yet to be established which, if any, of these mechanisms are more beneficial for learning. In this study, we utilize Java programming process data to investigate the interaction between novices and two different versions of the BlueJ pedagogical IDE, which differ substantially in terms of compilation mechanism and error message presentation. Specifically, we compare novices that used both BlueJ 3 and BlueJ 4 with those who exclusively used either and the effects of the order in which they transition between BlueJ versions. We find substantial differences between different cohorts in terms of error messages and compilation which provides evidence that programming environments play an important part in influencing the programming<br> practices of novices. This work supports the hypothesis that the choice of programming environment significantly affects user behavior with respect to specific programming interactions and therefore it is reasonable to expect a difference in how these environments affect learning.</p>

Data from: Late Triassic (Julian) conodont biostratigraphy of a transition from reefal limestones to deep-water environments on the Cimmerian terranes (Taurus mountains, southern Turkey)
Sections at Aşağiyaylabel and Yukariyaylabel, Taurus Mountains, southern Turkey, provide a rare opportunity to investigate conodont faunas in detail across a reef to slope transition. Intensive sampling of limestone beds (wackestones to packstones) through approximately 3 m at these locations has led to the recognition of a new lower Carnian (Julian 1/2) conodont fauna within the Kartoz and Kasimlar formations. Members of the subfamilies Paragondolellinae and Pseudofurnishiinae are recognized. The genus Kraussodontus is reported for the first time from the Taurus Mountains. Mosherella postkockeli and Mosherella praebudaensis sp. nov. occur within the lower Carnian Carbonate Member of the Kasimlar Formation from the Taurus Platform Units. The discovery of the new conodont assemblages from Aşağiyaylabel and Yukariyaylabel facilitates a correlation with faunal assemblages worldwide.

Inselberg, taxa, environment data for Inselberg floristics exemplify coast to inland OCBIL transition in a global diversity hotspot
<p>We examined floristics of granitoid inselbergs in the hitherto poorly documented southeastern region of the Southwest Australian Floristic Region (SWAFR) and adjacent Great Western Woodlands, addressing several hypotheses of OCBIL theory. We found exceptional taxon richness (1,550 taxa on 89 inselbergs, with 58 well-sampled inselbergs and 1493 taxa chosen for detailed analyses). Granite inselberg endemism declines towards the arid inland, though taxon richness does not. OCBILs are likely found up to 500 km inland, not ca. 300 km as previously hypothesized. Hybrids are extremely rare on the 58 inselbergs analysed, whereas rare species, including singletons, are abundant. Conversely, exotic weeds are less common than in the whole SWAFR flora (8.2% vs 12.8%). Granite plant communities are distributed in parallel bands to the south coast, approximating the general transition from the Esperance and Boylya Floristic Districts across the SWAFR boundary north into the Arid Zone's Great Western Woodlands. Positive correlations exist between several plant life forms and inselberg area, save for geophytes. There is a decrease from the coast inland for most life forms, except for annual and graminoid herbs that increase in taxa inland. Thus, inselberg floristics exemplify the coast-to-inland OCBIL transition in this global biodiversity hotspot.</p>
