    Short-Term Association between the Introduction of 2020 Low Traffic Neighbourhoods and Street Crime, in London, UK

    Between March and September 2020, 72 ‘Low Traffic Neighbourhoods’ (LTNs) were rapidly rolled out in London under emergency legislation. We examined the association between LTN implementation and street crime in October 2020 - February 2021 (‘post’), as compared to the same months in the previous two years (‘pre’). Overall crime trends in and around LTNs were more favourable than the background trend in Outer London, and similar to or slightly more favourable than the trend in Inner London. This pattern was also seen for numbers of direct attacks against the person - and this may underestimate the benefit per pedestrian, given evidence that LTN introduction is associated with increased walking

    An efficient asynchronous multiplier

    An efficient asynchronous serial-parallel multiplier architecture is presented. If offers significant advantages over conventional clocked versions, without some of the drawbacks normally associated with similar asynchronous techniques, such as excessive area. It is shown how a general asynchronous communication element can be designed and illustrated with the CMOS multiplier chip implementation. It is also shown how the multiplier could form the basis for a faster and more robust implementation of the Rivest-Sharmir-Adleman (RSA) public-key cryptosystem

    The Impact of 2020 Low Traffic Neighbourhoods on Levels of Car/Van Driving among Residents: Findings from Lambeth, London, UK

    We examined how residents’ driving changed after the implementation of low traffic neighbourhoods (LTNs) in Lambeth, London. We used postcode plus numberplate data from controlled parking zones, matched to annual MOT records. From 2018-2020 (‘pre’) to 2021-2023 (‘post’), mean past-year driving decreased by 0.7km/day among residents living inside the new LTNs and increased by 0.6km/day among residents in control areas elsewhere in Lambeth. This represents a difference-in-differences decrease of 1.3km/day (95% confidence interval 0.3 to 2.4) in LTN versus control areas, or a 6.4% relative decrease. Our findings suggest that residents started driving less once their area became an LTN

    Following a year of data gathering and planning during the 2010-2011 academic year, the University of Louisville launched the African American Male Initiative (AAMI) in the fall 2011 semester. The AAMI was designed using national best practices and current research findings as it relates to supporting African American male undergraduates. Now at the end of its first year, this practitioner’s brief provides an overview of the AAMI structure, design, and implementation

    This is a study at the intersection of sexuality and student involvement in higher education. Exploring the lived experiences of openly gay undergraduate men involved in elected student government, this study enlists a phenomenological queering that unconceals and reveals that which is otherwise hidden in elected student leadership. Eight men were selected for participation in this study, and all identified as openly gay before and after their election to undergraduate student government. These men come from varying U.S. geographies and positions, and conversations and themes were rendered through the methodological approach of hermeneutic phenomenology. Four major themes came from multiple participant conversations and journals. First, these men understood coming out and being out as deeply related to visibility and their work as leaders. They are more than just gay, and at the same time, they just so happen to be gay. Additionally, participants displayed independent ways of being within their outness. For example, some represented a palatable kind of being gay, and some navigated deep religious dissonance and other tensions within the (queer) margins. Re(-)presentation was also a major theme, as participants were advocates for their peers, and were “called” to this work of leadership. Finally, these men were leaders through their identities, and engaged in undergraduate student government as something that was bigger than them, but better because of them. This includes their call to leadership and student government, the political nature of this work, and a desire for things to be better. From this study, insights were gleaned that capture the nuances of this intersection of sexuality and student involvement in higher education. Specifically, this study is a calling to better understand what it means to live and work alongside students who hold these dual identities (out and elected in student government, and within student affairs). This includes a queering of student government and phenomenology, as well as a queering of van Manen’s (1997) existentials of lived space (spatiality), lived body (corporeality), lived time (temporality), and lived relationship to others (sociality)

    Experimental Evaluation and Thermodynamic System Modeling of Thermoelectric Heat Pump Clothes Dryer

    Get PDF
    Electric clothes dryers in the US consume about 6% of residential electricity consumption. Available electric clothes dryers today are either based on electric resistance (low-cost but energy-inefficient) or vapor compression (energy-efficient but high-cost). Thermoelectric dryers have the potential to alleviate the disadvantages of both through a low-cost, energy-efficient solution. This paper presents experimental results and steady state simulation of a prototype thermoelectric dryer. A thermoelectric model is coupled with a psychrometric dryer system model to design the experimental prototype. The results from the prototype are used to calibrate the model and identify important parameters that affect performance, such as relative humidity of air leaving the drum.
