Undergraduates’ Perceptions of Ideal Learning Environments

Four hundred and fifty three undergraduate students were surveyed at one CCCU institution regarding perceptions of what “exists” and what they “value” related to university pedagogy, learning activities, assessments, and learning relationships. Researchers ranked students’ values and examined gaps in students’ perceptions of what students say exists at the university as compared to what they value. The highest ranked values primarily related to learning relationships, including “demonstrates Christian ethics in interactions with others” and “integrates Christian worldview in the teaching of course content.” The factor that most explained satisfaction with teaching practices was the “Methods Factor” and the single item that most explained student satisfaction with teaching practices was, “provides interesting lessons.

Aspects of style and design in the Missa L'homme Armé tradition c. 1450-c. 1500

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This dissertation examines L 'homme armé Masses written during c. 1450-c. 1500, focusing on two aspects, the use of phrases 3 and 4 of the melody and the choice of pitch for the deployment of the respective cantus firmi. Altogether 34 Masses are considered. Chapter 1 reviews current information about the 1'homme armé melody itself with evidence given for the different endings to phrases 3 and 4 in the sources Mellon and Casanatense. Part I examines the deployment of the two key phrases in six contexts, Chapter 2 showing how large-scale structures are erected on them, and the next revealing a consistent pattern for using phrase 4 imitatively. Sounding of the two phrases simultaneously (and at times one of the outer portions of the ternary melody against the central one) is explored in Chapter 4. The influence of the motivic make-up of the polyphony on the choice of phrase is investigated in Chapter 5 and Chapter 6 deals with their manipulation for a musical portrayal of the Mass text. Part I concludes by reviewing where cadential contexts and the desire for full sonorities governs the choice of either phrase 3 or 4. Part ii examines the question of the pitch levels upon which different Masses deliver the source melody, starting with the G Mixolydian mode of the original. Settings presenting the song on G (either Mixolydian or transposedD orian) are considered the norm and are not reviewed. The exceptions are the six Naples Masses -a case is presented as to why not one Mass is in this mode. Completely canonic L'homme armé Masses are scrutinised, showing how composers avoided a problem encountered in anonymous Naples VI, where the comes at the subdiapente dictated the mode of the Mass. Josquin's F Ionian setting is investigated, then Compere's and Obrecht's E Phrygian readings and finally the D Dorian deliveries of Regis, Pipelare and La Rue

An Audience Centred Approach to Business Process Reengineering

This paper describes a method for process modelling which is designed to provide guidance to the business process modeller. The method has evolved from our experience of attempting to apply software process modelling approaches to business processes. A major influence on the method has been our observations that a pragmatic approach to notation selection is required in order to maintain a meaningful dialogue with end-users. Business process modelling methods typically fall into two camps. General methods attempt to describe the managerial activities which surround the modelling itself (Coulson-Thomas, 94; GISIP, 95). Specific methods, on the other hand, tend to concentrate on the details of a particular notational approach. However, as with programming languages or design methods, no single notational approach is best suited to all problems. Ideally, the process modeller should be able to incorporate the appropriate notational approach into some coherent generic modelling method.This paper addresses the needs of the modeller at the detailed level without prescribing a specific notation. This is achieved by describing categories of modelling activities which the modeller should undertake within process modelling, and suggesting how notations may be used within these categories. Our method is generally applicable, and is illustrated here by models of processes within the Construction industry

Predation Effects on Mid-marsh Ribbed Mussel Mortality, Cluster Size, and Facilitation of Cordgrass Growth

Reciprocal facilitation between Geukensia demissa, ribbed mussels, and Sporobolus alterniflorus, cordgrass, has a positive effect on salt marsh ecosystems. Mussel clusters enhance cordgrass growth and drought resistance and cordgrass provides attachment and shade for mussel aggregations. Along with benefits for both mussels and cordgrass, the mutualism facilitates increased biodiversity and shoreline stabilization and enhances marsh ecosystem functions. Aspects of mussel patch configuration including cluster size, perimeter and connectivity modulate the reciprocal facilitation effects of cordgrass and mussels on marsh ecosystems. In a northern South Carolina marsh system, mussel patch configuration positively influenced cordgrass biomass. Predation affected mussel patch configuration (e.g., cluster size), and patch configuration affected predation (e.g., mussel mortality). The effects of predation on mussel patch configuration and potential cascading effects on cordgrass biomass facilitation were examined in a field experiment varying predation (caged = no predation, uncaged = predation) and cluster size (0 to 240 m-2). Results from the 2 mo. experiment conducted in a mid-marsh elevation indicated no interaction between mussel mortality from predation and facilitation of cordgrass biomass. However, initial mussel cluster size positively affected cordgrass biomass. Predation effects on mussel patch configuration and potential cascading effects on cordgrass biomass within mid-marsh elevations apparently are not short-term, occurring over a few months, but may be more pronounced over longer periods (years) and/or in marsh elevations (low-marsh) more exposed to predators

Critical Assessment of Hybrid RANS-LES Modeling for Attached and Separated Flows

The objective of this study is to evaluate a recently proposed dynamic hybrid Reynolds-averaged Navier-Stokes (RANS)-Large Eddy Simulation (LES) modeling framework that seeks to effectively address issues regarding RANS-to-LES transition and explicit grid dependence inherent in most current hybrid RANS-LES (HRL) models. RANS-to-LES transition in the investigated dynamic HRL (DHRL) model is based on the physical concept of maintaining continuity of total turbulence production using two rigorously separated turbulent stress parameters, where one is obtained from the RANS model and the other from the LES model. Computations of two canonical test cases—two-dimensional turbulent channel flow and backward facing step flow—were performed to assess the potential of the DHRL model for predicting both attached and separated turbulent flows. This investigation attempts to evaluate the ability of the DHRL method to reproduce the detailed physics of attached and separated turbulent flows, as well as to resolve the issues concerning log-layer mismatch and delayed break down of separated shear layers. The DHRL model simulation results are compared with experimental and DNS data, along with the computational results for other HRL and RANS models. In summary, these comparisons demonstrate that the DHRL framework does address many of the weaknesses inherent in most current HRL models

Lower pollen nutritional quality delays nest building and egg laying in Bombus terrestris audax micro-colonies leading to reduced biomass gain

This version of the article has been accepted for publication, after peer review (when applicable) and is subject to Springer Nature’s AM terms of use, but is not the Version of Record and does not reflect post-acceptance improvements, or any corrections. The Version of Record is available online at: http://dx.doi.org/10.1007/s13592-021-00885-3The performance of Bombus terrestris micro-colonies fed five diets differing in pollen species composition and level of nine essential amino acids (EAA; leucine, lysine, valine, arginine, isoleucine, phenylalanine, threonine, histidine, methionine) was assessed for 37 days by recording total biomass gain, nest building initiation, brood production (eggs, small and large larvae, pupae, drones), nectar, and pollen collection. Stronger colony performance was linked to higher amino acid levels but no consistent differences in biomass gain were recorded between mono- and poly-species diets. Poorest performance occurred in micro-colonies offered pure oilseed rape (OSR) pollen which contained the lowest EAA levels. Reduced micro-colony development (delayed nest initiation and lower brood production) was related to OSR proportion in the diet and lower EAA levels. Results are discussed in relation to selection of plant species in the design of habitats to promote bee populations
