Researchers and teachers have noted the power of students reading text sets or multiple texts on the same topic, and numerous articles have been published with examples of and frameworks for text set construction. This study aims to traces the theoretical assumptions of these frameworks and explores their distinct implications and tensions for understanding disciplinary literacy in English language arts (ELA).

The author draws on three frameworks, using a focal article for each: cognitive (Lupo et al., 2018), critical (Lechtenberg, 2018) and disciplinary (Levine et al., 2018), and connect those articles to other research studies in that tradition. Separately, the author describes each of the three text set frameworks’ design principles. Then, across frameworks, the author analyze the disciplinary assumptions around each framework’s centering texts, epistemological goals and trajectories.

The centering text, goals and trajectories of each framework reflect its underlying epistemological lens. All frameworks include a text that serves as its epistemological center and the cognitive and disciplinary frameworks, both rely on progressions of complexity (knowledge/linguistic and literary, respectively). The author traces additional alignments and tensions between the frameworks and offer suggestions for possible hybridities in reading modality and reading volume.

Many articles have been written about models of text set construction, but few have compared the assumptions behind those models. Examining these assumptions may help English teachers and curriculum designers select texts and build curriculum that leverages the strengths of each model and informs researchers’ understanding of disciplinary literacy in ELA.

Research has documented how white teachers often fall short of their anti-racist intentions. However, much of this research is done with preservice teachers or teachers across disciplines. The authors investigate stories in which white English teachers who teach substantial proportions of black students and who self-reported anti-racist goals nevertheless fell short of those goals. The purpose of the study is to understand the tensions between racial liberalism and racial literacy in their pedagogy.

The authors snowball sampled 12 veteran white high school English teachers (3–27 years’ experience) who taught in schools with substantial proportions of black students. The authors used a two-stage interview process to narrow the sample to 7 teachers who confirmed their anti-racist intentions and who wrote narratives of moments when they tried to be anti-racist, but the lesson failed in some way. The authors used a three-stage narrative analysis to analyze how racial liberalism and racial literacy were reflected in the narratives.

The veteran English teachers, despite their anti-racist intentions, told narratives that reflected racial liberalism, portraying racism as an individual and interpersonal phenomenon. Some narratives showed teachers who had taken steps toward racial literacy, but no narratives showed a fully developed sense of racial literacy, portraying the layers of institutional and structural racism in English education.

The sample suggests that veteran white English teachers are subject to similar limited racial literacies as novice teachers. While the authors found glimmers of racial literacy, they still note the work necessary to equip veteran English teachers with the racial literacies necessary for anti-racist instruction. The authors propose directions for teacher education, systemic support and professional development.

In this chapter, we consider music as a tool for emotional regulation in relation to disability, which can be employed to counter the dehumanisation of disabled people that arises from unregulated emotional responses to disability. Responding to Julia Kristeva's presentation of non-disabled encounters with disability as causing a physical or psychical death, Alison Duncan Kerr's arguments on the rationality of regulating emotions in encounters where unregulated emotions have negative effects on the self and others are brought together through Rebecca Jiggens' cultural model of understanding the significance of disability to illustrate the irrationality and moral paucity of ableism. We argue that music can play a role in regulating the emotions typically felt towards the disabled. Kristeva's idea that disability wounds or even kills the abled is insightful, but if we are right, then the tight connection between death and emotional reactions to disability could be overcome through the process of emotion regulation.

The purpose of this study is to develop and test a two-stage model of sales opportunity outcomes, and thus identify the factors that influence the likelihood of a salesperson pursuing and winning a sales deal.

Using a longitudinal design, the authors collect data on 330 sales opportunities at two different time periods from two distinct sources and conduct data analysis using hierarchical linear modeling.

In the first stage, the authors find that the salesperson’s decision to pursue the opportunity is influenced by the strategic value of the client’s business and the concreteness of the opportunity. In the second stage, the authors find that the likelihood of winning the opportunity is influenced by the extent of the salesperson’s specialization, closeness to the buying center, company’s competitive position and fit with the client’s value orientation.

The authors have examined discrete sales opportunities independent of ongoing business relationships; future research should explore transactions that are embedded within customer relationships.

The authors highlight the importance of evaluating sales opportunities at the beginning of the sales process and suggest some specific variables that relate to the selling context.

The authors analyze factors that influence the decision of the salesperson to pursue an opportunity or not, as well as factors that influence the likelihood of winning a deal or not.

As organisational culture has become recognised as a significant phenomenon for understanding both managerial and organisational dynamics and development, two requirements have risen. On the one hand, we need a conceptual framework for comprehending culture and, on the other hand, we need methodologies for making culture visible. This article offers both – initially describing what is becoming a major conceptual framework for culture work, and then outlining a workshop methodology for making culture visible. An extended case illustrates both the framework and one form of culture‐surfacing methodology.

This paper aims to investigate the effects of different volume fractions of Al₂O₃-water nanofluid on flow and heat transfer under chaotic convection conditions in an L-shaped channel, comparing the difference of numerical simulation results between single-phase and Eulerian–Lagrangian models.

The correctness and accuracy of the two calculation models were verified by comparing with the experimental values in literature. An experimental model of the L-shaped channel was processed, and the laser Doppler velocimeter was used to measure the velocities of special positions in the channel. The simulated values were compared with the experimental results, and the correctness and accuracy of the simulation method were verified.

The calculated results using the two models are basically consistent. Under the condition of Reynolds number is 500, when the volume fractions of nanofluid range from 1% to 4%, the heat transfer coefficients simulated by single-phase model are 1.49%–25.80% higher than that of pure water, and simulated by Eulerian–Lagrangian model are 3.19%–27.48% higher than that of pure water. Meanwhile, the friction coefficients are barely affected. Besides, there are obvious secondary flow caused by lateral oscillations on the cross sections, and the appearance of secondary flow makes the temperature distributions uniform on the cross section and takes more heat away, thus the heat transfer performance is enhanced.

The originality of this work is to reveal the differences between single-phase and two-phase numerical simulations under different flow states. The combination of chaotic convection and nanofluid indicates the direction for further improving the heat transfer threshold.

THE first part of Professor Duncan Dowson's paper (March/April issue) dwelt on late 19th century development of machinery outstripping the performance of available lubricants. Contemporary lubricant research, and personalities involved, where described, leading to the concept of fluid‐film lubrication, documented by Professor Osborne Reynolds' paper read to the Royal Society in 1886.

Friction and wear are very important factors in predicting the performance of journal bearings, particularly under heavy load in start-up processes. However, there are few relevant studies on the numerical model. This study aims to establish a transient-mixed lubrication model to predict the performance of journal bearings, focusing on the friction and wear behavior under heavy load during start-up.

The average Reynold equation, three-dimensional energy equation, shear stress model for friction and Archard model for wear are coupled in the transient model by finite difference method. The linear wear simulation method is bought out to reduce the update times and the calculation time.

The different start-up accelerations and linear wear times set are compared and discussed, which indicates a reasonable start-up acceleration is necessary for journal bearings under heavy load during start-up, and setting linear wear times is an effective method to reduce the simulation time significantly. Furthermore, the wear profile in the start-up process spreads in both the clearance and circumferential directions, but mainly in the clearance direction, which increases the minimum film thickness and affects the friction performance.

This study is of great significance for the numerical prediction of the transient performance of journal bearings during start-up considering friction and wear.

Multitilting-pad journal bearings (MTPJBs) used in large-scale hydraulic turbines often suffer from complex operating conditions, which greatly influence the overall performance of the rotating machine. The purpose of this study is to establish a thermal-elastic-hydrodynamic lubrication model for MTPJBs that can predict the static and dynamic characteristics of high-speed and heavy-load MTPJBs under different operating conditions.

A thermo-elasto-hydrodynamic lubrication model considering the turbulence effect is proposed for high-speed and heavy-load TPJBs, which is solved using the coupled finite difference method and finite element method. The model considered the turbulence effect, thermal energy diffusion, viscosity–temperature–pressure relationship and elastic deformation of the pads. The influences of the operating conditions on static and dynamic characteristics of tilting pad journal bearings were analyzed in depth.

The operating conditions have a strong effect on the static properties of the bearings. The dynamic characteristics of the TPJB were the most influenced by the shaft speed. The effects of the load direction on the dynamic properties of the TPJB were much stronger than those of the static characteristics.

This study used analytical methods and models to provide theoretical guidance for evaluating lubricating characteristics, assembling conditions and overall health.
