The species name refers to the two anteroventral spine-like setae on the hind femur.Published as part of Wheeler, Terry A. & Sinclair, Bradley J., 2019, Systematics of Paraleucopis Malloch with proposal of Paraleucopidae, a new family of acalyptrate Diptera, pp. 301-328 in Zootaxa 4668 (3) on pages 308-309, DOI: 10.11646/zootaxa.4668.3.1, http://zenodo.org/record/344945
Representing silk design: Nicholas Joubert de L'Hiberderie and Le dessinateur pour les etoffes d'or, d'argent et de soie (Paris, 1765)
No full textLe Dessinateur pour les étoffes d'or, d'argent et de soie was published in Paris in 1765 depite the reservations of the silk-weaving guild of Lyons, receiving a good response in the Enlightenment press. As the first description on French of the trade of silk designer to appear in the public domain, it has become an important work on which much subsequent history has been based, often rather uncritically. This article delves into the representation of design offered by this text, evaluating it against the personal experience of its author, the literary and manufacturing heritage on which he drew, and the readership for women it was intended. The analysis is based on the form and content of the book, the structure, vocabulary and illustrations. Comparative data are drawn from two other important publications on silk manufacture, the relevant sections of Denis Diderot's Encyclopédie and Jean Paulet's L'Art du fabriquant
Marketing communications plan for L.E. Jones company Menominee, Michigan
No full textThe author researched the feasibility of improving marketing communications for L.E. Jones Company of Menominee, Michigan. Based on career experience and scholarship gained through the Cardinal Stritch Master of Business Administration program, the author was able to identify the problems facing the firm, analyze the marketing communications needs, recommend various alternatives, assist in the selection of alternatives, and create the actual advertising and sales support materials. These improvements in marketing communications will permit the firm to more confidently pursue new business in an increasingly competitive market
Experimental and quasi-experimental design in occupational health psychology
No full textVarious research methods such as observation, interview, survey, experiment, or quasi-experiment have been utilized to advance the literature in occupational health psychology (OHP) with the goal of improving the quality of work life and promoting healthy workplaces (Chen, DeArmond, & Huang, 2007). Among these methods, experiments are likely considered the most robust method to investigate causal relationships between variables of interest. The unique strength of experiments is attributed to the fact that “causes” are manipulated (either deliberately or not) and their “effects” or “impacts” are systematically assessed in a controlled setting
On Sense, Tone, and Accompanying Thoughts
No full textThe paper deals with Frege's distinction between sense and colouring or tone as applied both to proper names and to compound sentences. It argues that Frege's way of drawing this distinction is unsatisfactory, much for the same reasons as Grice's theory of conventional implicature is a non starter. The author suggests that tone may contributes to assertoric content depending on contextually specified circumstances. The phenomenon of linguistic underdetermination is very widespread, and tone is only the tip of an iceberg that we need to explore more fully.
The paper deals with Frege's notions of sense and tone within the framework of recent theories of contextualism, literalism and multi-dimensionalism. Dummett's account of Frege's account of sense is reviewed and extended. The author suggests that tone differs from sense only as regards a higher degree of undeterdeterminationa and occasion sensitivity. Tone contributes to assertoric content, and differs from conventional implicatures, as described by Paul Grice and his followers
Jets and Prompt Photons in Photoproduction at ZEUS
No full textIn the ZEUS experiment at HERA, photoproduction processes have been studied for photon-proton centre-of-mass energies in the range 100 ! W flp ! 300 GeV and jet transverse energies extending to E jet T ¸ 70 GeV. The data contribute to our understanding of QCD dynamics, and also provide new constraints on the photon's parton density. talk given at the XXIX International Conference on High Energy Physics (ICHEP '98) Vancouver, Canada. August, 1998. 1 Introduction There has been tremendous progress in the understanding of photon induced reactions since the start of HERA operation. Up to the end of 1994, HERA had delivered a total of 7 pb \Gamma1 of ep data. The analysis of this data was fruitful. ZEUS was able to clearly establish evidence for both the direct and the resolved classes of process. These are illustrated at leading order (LO) in Figure's 1(a) and (b). e - p (a) e - p (b) e - p (c) Figure 1: Examples of leading order diagrams for (a) direct photoproduction, (b) re..

Optimizing stakes in simultaneous bets
No full textWe want to find the convex combination S of iid Bernoulli random variables that maximizes P(S ≥ t) for a given threshold t. Endre Csóka conjectured that such an S is an average if t ≥ p, where p is the success probability of the Bernoulli random variables. We prove this conjecture for a range of p and tGreen 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.Applied Probabilit
Met Markov ketens op zoek naar de Zero Variance Importance Sampling verdeling
No full textStandaard Monte Carlo is niet geschikt voor het analyseren van Rare Events. We laten zien dat we bij dit soort problemen Importance Sampling kunnen toepassen en hoe we de Zero Variance verdeling kunnen vinden. Deze verdeling hangt echter af van constanten waar we de waarde niet van weten, maar door deze constanten te benaderen krijgen we een benadering van de verdeling. We passen deze methode toe op een eenvoudig (bonimiaal) Credit Risk model. Door de Zero Variance verdeling beter te benaderen, kunnen we een grotere variantie reductie realiseren. We hebben daarom een nieuwe methode ontwikkeld die na elke iteratie een betere benadering van deze verdeling geeft. De variantie reductie bij het gebruik van deze methode is aanzienlijk maar de methode is niet eenvoudig te implementeren.Applied MathematicsDelft Institute of Applied MathematicsElectrical Engineering, Mathematics and Computer Scienc
