    Integrated Environmental PlanningCycling is an excellent mode of transportation. Choosing to commute by bicycle helps to reduce emissions and noise, and alleviate road congestion. Situated in the mountains along the Columbia and Kootenay rivers, Castlegar and the surrounding area is an amazing place with many different roads and trails suitable for bike riding. Selkirk College students and staff should take advantage of this, and be aware of the recreation opportunities available in our backyard. The intention [of] this project is to communicate the distance, elevation gain, and difficulty of cycling routes to Selkirk College. This project's purpose is to spark the idea that cycling to Selkirk College is a fun, accessible, and green way to get to school

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Ophthalmology. 2005 Feb;112(2):208-18; discussion 219. Mitomycin C modulation of corneal wound healing after photorefractive keratectomy in highly myopic eyes. Gambato C, Ghirlando A, Moretto E, Busato F, Midena E. SourceRefractive Surgery Service and Antimetabolite Therapy Research Unit, Department of Ophthalmology, University of Padova, Padova, Italy. Abstract PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes. DESIGN: Prospective, double-masked, randomized clinical trial. PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia. METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months). MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH. RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively). CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK. Comment in Ophthalmology. 2006 Feb;113(2):357; author reply 357-8

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    On the Dewar-Chatt-Duncanson model for catalytic gold(I) complexes

    No full text
    We provide a rigorous model-free definition and a detailed theoretical analysis of the electron- charge displacements making up the donation and back-donation compo- nents of the Dewar–Chatt–Duncanson model in some realistic catalytic inter- mediates of formula L–AuI–S in which L is an N-heterocyclic carbene or Cl and S is an eta2-coordinated substrate containing a C C multiple bond. We thus show, contrary to a widely held view, that the gold substrate bond is characterized by a large p back-donation component that is comparable to, and often as large as, the s donation. The back-donation is found to be a highly tunable bond component and we analyze its relationship with the nature of the auxiliary ligand L and with structural (interdependent) factors such as metal–substrate bond lengths and carbon pyramidalization

    A Multi-Language Comparison of Influences on Author Verification using Character N-Grams

    No full text
    We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc

    A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C

    No full text
    Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (&gt; 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

    A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration

    No full text
    Accurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic

    'Be polite, be professional, be prepared to kill': counterinsurgency, masculinity and British military doctrine

    Full text link
    Contemporary counterinsurgency has been characterised by a shift from the ‘kill or capture’ of insurgents to prioritising winning over civilian populations. This focus on the population brings a particular skillset to the centre of military practice. Prioritising understanding culture, training, mentoring and relationships, practices previously associated with peacekeeping operations are conducted alongside combat. Feminist literature on peacekeeping has traced the relationship between entrenched hierarchies of gender and race in military institutions and abuses perpetrated by peacekeepers. This thesis contributes to that literature. It focuses on the British Armed Forces to analyse how identity is constructed in relation to contemporary counterinsurgency, in order to understand changing military roles and the potential impact on civilian populations. The thesis comprises a feminist discourse analysis of select British military doctrine. Doctrine draws together practice, teaching, and policy and offers a productive site to study institutional identity. The analysis shows how these non-combat practices are made sense of in relation to different configurations of masculinity, which don’t evoke combat or aggression. Nonetheless, they are constructed as masculine identities, hierarchical in organisation and constituting relations of power. I argue this recourse to masculinity enables the framing of non-combat practices as warfare and so valuable military activity. However, this framing simultaneously restrains the ways in which they can be understood. The thesis further highlights an ambiguity in the texts which argue both for widespread institutional adaption to the practices, and their limitation to a specific specialism and personnel. This ambiguity I argue is productive for an institution facing an uncertain future, leaving open possibilities for reform, or to revert to focussing on traditional understandings of core combat related military tasks. This thesis contributes to feminist debate about the possibility for military reform, and the capacity for Armed Forces to act as agents for peace. I argue that military reform is possible and occurring; the British Armed Forces are developing more sophisticated approaches to gender, human security and culture. However, whilst this is likely to have some benefit, the (re)establishment of gendered and raced hierarchies, limit the extent to which such reform offers meaningful change
