Reliability of a high-intensity endurance cycling test.

This study assessed the reproducibility of performance and selected metabolic variables during a variable high-intensity endurance cycling test. 8 trained male cyclists (age: 35.9 ± 7.7 years, maximal oxygen uptake: 54.3 ± 3.9 mL·kg - 1·min - 1) completed 4 high-intensity cycling tests, performed in consecutive weeks. The protocol comprised: 20 min of progressive incremental exercise, where the power output was increased by 5% maximal workload (Wmax) every 5 min from 70% Wmax to 85% Wmax; ten 90 s bouts at 90% Wmax, separated by 180 s at 55% Wmax; 90% Wmax until volitional exhaustion. Blood samples were drawn and heart rate was monitored throughout the protocol. There was no significant order effect between trials for time to exhaustion (mean: 4 113.0 ± 60.8 s) or total distance covered (mean: 4 6126.2 ± 1 968.7 m). Total time to exhaustion and total distance covered showed very high reliability with a mean coefficient of variation (CV) of 1.6% (95% Confidence Intervals (CI) 0.0 ± 124.3 s) and CV of 2.2% (95% CI 0.0 ± 1904.9 m), respectively. Variability in plasma glucose concentrations across the time points was very small (CV 0.46-4.3%, mean 95% CI 0.0 ± 0.33 to 0.0 ± 0.94 mmol·L - 1). Plasma lactate concentrations showed no test order effect. The reliability of performance and metabolic variables makes this protocol a valid test to evaluate nutritional interventions in endurance cycling

High Impedance Arc Fault Detection in a Manhole Environment.

The scope of this thesis was to develop a prototype high-impedance arc detection system that a utility worker could use as an early warning system while working in a manhole environment. As part of this system sensors and algorithms were developed to increase the sensitivity of detecting an arc while ignoring loads that can give false positive signatures for arcing. The latest technology was used to repeat measurements performed in previous research from decades ago that lacked in sampling speed and amplitude resolution. Several types of arcs were produced and analyzed so to establish a library of various waveform and frequency signatures. The system was constructed as a development unit and is currently gathering information in the field. Data being collected will be analyzed so future revisions will give higher confidence levels of arc detection. Other future plans involve designing a more compact and portable unit

What's That Noise? Or, a Case Against Digital Privacy as a Matter of Regulation and Control

Digital privacy is typically understood as the restriction of access to personal information and user data. This assumes regulation and control on the part of governments and corporations, realized through various laws and policies. However, there exists another realm bearing on digital privacy. This realm involves a wider network of actors carrying out practices and techniques beyond merely governmental and corporate means: users who engage and manipulate digital privacy software that is created by coders, as well as the software itself for the ways in which it mediates the relationship between users and coders. The dissertation argues that by focusing attention on this other realm of coders, users and software interacting with one another we as analysts develop alternative understandings of digital privacy, specifically by attending to each actors noisemaking: the deliberate (or even incidental) process of obfuscating, interrupting, precluding, confusing or misleading access to digital information. The dissertation analyzes how each of these three actors engage in noisemaking across three different types of encrypted Internet systems: The Onion Router web browser; the WhatsApp instant messaging service; the SpiderOak One file hosting service. These relatively taken-for-granted actors instruct the academy that digital privacy is less about regulating and controlling information as much as it is about surrendering control over information management and security. The dissertation demonstrates that digital privacy thus ought to be understood as a reflection of the variegated, contingent and incidental nature of social and political forces unfolding at the edge of and even beyond the purview of governments and corporations

Spillovers from immigrant diversity in cities

Using comprehensive longitudinal matched employer-employee data for the U.S., this paper provides new evidence on the relationship between productivity and immigration-spawned urban diversity. Existing empirical work has uncovered a robust positive correlation between productivity and immigrant diversity, supporting theory suggesting that diversity acts as a local public good that makes workers more productive by enlarging the pool of knowledge available to them, as well as by fostering opportunities for them to recombine ideas to generate novelty. This paper makes several empirical and conceptual contributions. First, it improves on existing empirical work by addressing various sources of potential bias, especially from unobserved heterogeneity among individuals, work establishments, and cities. Second, it augments identification by using longitudinal data that permits examination of how diversity and productivity co-move. Third, the paper seeks to reveal whether diversity acts upon productivity chiefly at the scale of the city or the workplace. Findings confirm that urban immigrant diversity produces positive and nontrivial spillovers for U.S. workers. This social return represents a distinct channel through which immigration generates broad-based economic benefits

AlignStat: a web-tool and R package for statistical comparison of alternative multiple sequence alignments

Background: Alternative sequence alignment algorithms yield different results. It is therefore useful to quantify the similarities and differences between alternative alignments of the same sequences. These measurements can identify regions of consensus that are likely to be most informative in downstream analysis. They can also highlight systematic differences between alignments that relate to differences in the alignment algorithms themselves. Results: Here we present a simple method for aligning two alternative multiple sequence alignments to one another and assessing their similarity. Differences are categorised into merges, splits or shifts in one alignment relative to the other. A set of graphical visualisations allow for intuitive interpretation of the data. Conclusions: AlignStat enables the easy one-off online use of MSA similarity comparisons or into R pipelines. The web-tool is available at AlignStat.Science.LaTrobe.edu.au. The R package, readme and example data are available on CRAN and GitHub.com/TS404/AlignStat

The Old French and Chaucerian fabliaux : a study of their comic climax

Includes index.Bibliography: pages 201-213.This study is about the comic structure of the fabliaux. The survival of approximately 160 Old French fabliaux, some in several versions and in different manuscripts, attests to their widespread popularity in the Middle Ages. Chaucer's fabliaux are essentially the same genre as the Old French fabliaux, and hence their humor is essentially the same. Our own enjoyment of them is in its own way quite refined and even analogous to certain spiritual experiences. In focusing on the comic climax of the fabliaux, I necessarily talk about their structure, which has its own function within the story regardless of what influenced it or caused it to be there and regardless of what it reflects.Introduction -- Preparation for the climax: The showing -- Preparation for the climax The telling -- The comic climax -- Humor in the fabliaux -- Chaucer's fabliaux -- Conclusion.Digitized at the University of Missouri--Columbia MU Libraries Digitization Lab in 2012.

The goal dependent automaticity of drinking habits

In recent treatments of habitual social behaviour, habits are conceptualised as a form of goal-directed automatic behaviour that are mentally represented as goal-action links. Three experiments tested this conceptualisation in the context of students’ drinking (alcohol consumption) habits. Participants were randomly assigned to conditions where either a goal related to drinking behaviour (socialising) was activated, or an unrelated goal was activated. In addition, participants’ drinking habits were measured. The dependent variable in Experiments 1 and 2 was readiness to drink, operationalised by speed of responding to the action concept “drinking” in a verb verification task. Experiment 3 used uptake of a voucher to measure drinking behaviour. Findings supported the view that when habits are established, simply activating a goal related to the focal behaviour automatically elicits that behaviour. These findings are consistent with a goal-dependent conception of habit. Possibilities for interventions designed to attenuate undesirable habitual behaviours are considered
