Abstract

Effective discussion is inextricably linked to democracy. Social studies curriculum and instruction should engage students in practicing democratic skills and habits of mind. This case study provides a microanalysis of one U.S. History teacher’s commitment to fostering discussion in her classroom as a theorized pedagogical practice. A better understanding of what motivates teachers to engage students in classroom discussions paralleled with rich descriptions of how this teacher plans and implements discussion could encourage others to try this approach to teaching and learning.

Abstract

Reports on office planning's new type (known as ‘open planning’( with a case study of the principal innovator in this procedure's development, Dexion Ltd, in the UK, which was heavily involved in the wall (office) partitioning range. Evaluates and discusses all of the company's various spin off companies and the products therein. Examines also the sales performance and marketing approach of the company and its good and bad points. Closes by making recommendations for Dexion's Partitioning Division including sales promotion and distribution channel development. Concludes that the recommended actions would establish Dexion as a major player in its market, allowing other Dexion products to break into the market.

Abstract

Purpose

The purpose of this paper is to develop an indigenous three‐dimensional computational code and apply it to compare flow and heat transfer characteristics for inline and staggered arrangement of circular tubes in a tube bundle.

Design/methodology/approach

A finite‐volume based computational code is developed to solve the momentum and energy equations for flow through a three‐dimensional rectangular channel and past built‐in tube bundles having inline and staggered arrangement. The approach is based on SIMPLE algorithm. The basic conservation equations of mass, momentum and energy are solved over a body‐fitting grid on the physical domain to obtain the flow and temperature fields.

Findings

Heat transfer and pressure drop are compared for inline and staggered tube arrangements in a tube bundle over range of Reynolds numbers 300 ≤ Re ≤ 800. Results are validated suitably against those available in literature.

Research implications

Tube‐fin heat exchangers with continuous fins on a tube array are commonly used in air‐conditioning industry and in air‐cooled condensers of power plants. The flow structure within the finned tube bank is complex due to the presence of a circular tube, which causes flow acceleration over the fin surface and flow separation on the back side of the tube resulting in low velocity wake region. The present study provides a better understanding of flow behavior and heat transfer for inline and staggered arrangement of tube bundles in tube‐fin heat exchangers at different Reynolds numbers.

Originality/value

A numerical code based on finite volume method has been developed and used for computations to predict heat transfer and pressure drop characteristics for flow past inline and staggered arrangement of circular tubes. Predictions are made from the computed results about suitability of staggered/inline tube arrangements in a given range of Reynolds number.

Abstract

A numerical study is performed to investigate turbulent Couette flow and heat transfer characteristics in concentric annuli with a slightly heated inner cylinder moving in the flow direction. A two‐equation k‐ε turbulence model is employed to determine the turbulent viscosity and the turbulent kinetic energy. The turbulent heat flux is expressed by Boussinesq approximation in which the eddy diffusivity for heat is given as functions of the temperature variance t2‐ and the dissipation rate of temperature fluctuations εt, together with k and ε. The governing boundary‐layer equations are discretized by means of control volume finite‐difference technique and numerically solved using a marching procedure. It is disclosed from the study that the streamwise movement of the inner core causes substantial reductions in the turbulent kinetic energy and the temperature variance, particularly near the inner wall region, resulting in the deterioration of the Nusselt number, and that an attenuation in heat transfer performance is induced by the velocity ratio of the moving inner cylinder to the fluid flow.

Abstract

Purpose

This study aims to investigate how two collaborative methods – selection and synthesis – influence knowledge convergence when people articulate a new strategic direction driving transformation within the organization.

Design/methodology/approach

The study is based on a longitudinal field experiment developed in four organizations involving 82 employees over a three-month process. Inspired by dynamics governing flocks as complex adaptive systems, selection and synthesis have been separately used in two sets of companies. Primary and secondary data have been largely collected and analyzed throughout the whole process.

Findings

This study describes how the two alternative methods differently influenced two kinds of knowledge convergence. While selection triggers a general and static knowledge convergence and the propagation of individual knowledge over time, synthesis fosters a local and dynamic knowledge convergence where individuals tend to propagate knowledge generated collectively.

Research limitations/implications

This research offers insights into understanding the influence of alternative collaborative methods on the creation and propagation of knowledge when people are converging toward a new strategic direction. From a theoretical perspective, it contributes to complex adaptive system theory, highlighting the role of knowledge convergence and emergence through collaboration.

Practical implications

This research offers insights to managers who deal with the complexity of the engagement of different stakeholders during collaborative processes, offering some actionable takeaways to foster knowledge convergence by alternatively employing selection and synthesis.

Originality/value

This paper contributes to the management and social information processing literature emphasizing the role of knowledge convergence emerging from the complex interactions among multiple stakeholders.

Abstract

A three‐dimensional numerical study was conducted to assess the heat transfer performance of extended fins in a two‐row finned tube heat exchanger. Fins under investigation were plane and slit types. A finite volume discretization method and a SIMPLE‐based solution algorithm were, respectively, applied to working differential equations and their discrete counterparts to compute the gas velocities and pressure. The temperatures of solid and gas phases were computed from the same energy equation with different diffusivities and prescribed convective fluxes. The main objective of this study was to compare the transfer capabilities of the two investigated fin shapes. Their capabilities as a whole are presented in terms of the computed Nusselt number and the pressure drop across the flow passage.

Abstract

Purpose

The purpose of this paper is to develop a generic framework for the assessment of VMI implementation. The framework is used for the analysis of multiple case studies in German hospitals to discuss the feasibility of VMI in the German blood supply chain.

Design/methodology/approach

The methodology is twofold. In a first step, the literature is reviewed and a generic theoretical VMI framework is developed. In a second step, the case study methodology is applied to 13 cases to assess the feasibility of VMI in the German blood supply chain.

Findings

The paper contributes a generic framework for assessing the implementation of VMI in seven steps. The research proposed that hospitals hesitate to enter a VMI relationship for critical resources such as blood. Hospitals fear losing control over critical resources.

Research limitations/implications

The unit of analysis is hospitals in Germany and the case studies do not target the suppliers in the supply chain. The paper contributes three propositions regarding VMI in the healthcare/blood supply chain.

Practical implications

A generic framework for assessing the applicability and feasibility of VMI is provided which supports managers with the implementation of VMI in a supply chain.

Originality/value

The paper is one of the first papers targeting inventory and supply chain management in the German blood supply chain. It provides a generic framework for the assessment of the feasibility of VMI.

Abstract

Purpose

The purpose of this paper is to gain a deeper understanding of the attributes of effective complaint management in business‐to‐business relationships, and to reveal the underlying benefits that buying organizations are looking for when complaining.

Design/methodology/approach

A semi‐standardized qualitative technique called laddering was applied successfully to an online environment with 22 representatives of companies in the manufacturing industry participating.

Findings

The resulting hierarchical value map displays 13 attributes which exemplify the complaint resolution management expectations. A total of 14 constructs represent consequences of such resolution activities, while four constructs can be interpreted as values. Take “Quick action” is the most important of the expected attributes and behaviours of complaint resolution management. Four consequences seem to dominate the assessment: Financial benefits, Prevention of future problems, Solution, and Effective resolution handling. “Maintain supplier relationships” appears as a dominant value in the perceptions of respondents, with half of them mentioning this as an end.

Research limitations/implications

Owing to the exploratory nature of the study in general and the scope and size of its sample in particular, the findings are tentative in nature. The study involved a group of representatives of large UK manufacturing companies with complaint handling responsibilities and so the results cannot be generalised.

Originality/value

The findings enrich the existing limited stock of knowledge on complaint management in business relationships by developing a deeper understanding of the attributes that complaining customer companies desire from suppliers, as well as the underlying business logic (i.e. values) for these expectations. The quality of the results also suggests that the laddering questionnaire technique can be transferred effectively to an online environment.
