Abstract

Coffee shops are becoming more aware that brand loyalty can be an effective strategy for securing a competitive edge in business. To supplement current understanding of the importance of coffee shop branding, this study investigates the role of personality traits and congruity in the formation of brand loyalty. This study finds that personality traits have direct effects on congruity and customer satisfaction, the two defining factors of brand loyalty. Overall, our results suggest that the interaction of personality traits, congruity, and satisfaction is essential to the process of influencing coffee shop customers’ brand loyalty.

Abstract

Sara Lee Corporation's acquisition binge in the 1980s and 1990s left the company with a portfolio of vastly different businesses operating independently of one another. It had experienced rapid top-line growth, but at the same time cash flows had declined. Sara Lee ignored both internal and external warning signs until a major transformation plan became necessary. This case examines the company's multiple turnaround attempts. The learning objective of the case is to analyze “early stage” turnaround efforts by examining how the company found itself in decline, evaluating its attempts to improve its performance, and assessing the turnaround plan.

(1) Learn to identify a specific challenging moment when reading and analyzing a turnaround plan; (2) address the implementation problems of an early stage turnaround and discuss exit options; (3) evaluate when a change of long-held beliefs and decades-long strategy by a company is warranted; (4) evaluate Sara Lee's marketing strategies in light of the disappointed retail and wholesale customers; and (5) show the similarities in traits between turnaround managers and high-growth entrepreneurs.

Abstract

Purpose

The purpose of this paper is to explain why Singapore is a success story today despite the fact that its prospects for survival were dim when it became independent in August 1965.

Design/methodology/approach

This paper describes the changes in Singapore’s policy context from 1959 to 2016, analyses the five factors responsible for its success and concludes with advice for policy makers interested in implementing Singapore-style reforms to solve similar problems in their countries.

Findings

Singapore’s success can be attributed to these five factors: the pragmatic leadership of the late Lee Kuan Yew and his successors; an effective public bureaucracy; effective control of corruption; reliance on the “best and brightest” citizens through investment in education and competitive compensation; and learning from other countries.

Originality/value

This paper will be useful to those scholars and policy makers interested in learning from Singapore’s success in solving its problems.

Abstract

It is salient to be acquainted with the key elements that determine educational tourists’ decision in selecting an overseas destination while considering the rise of international competition amidst nations concerning international students. There has been a growth in the number of nations committed to attracting educational tourists. This issue is evident in countries involved in higher education (HE), such as Northern Cyprus, identified as an edu-tourism destination. Northern Cyprus can attract a whopping number of tourists, and the higher population is most likely to be made up of international students regardless of its interdiction on direct flights and political pressure. This chapter centres on analysing educational tourists’ motivators in selecting a tourism education destination abroad and on revealing effective recruitment and promotion plans towards attracting them. The chapter includes the descriptions and discussions of educational tourism, the HE industry over the years, globalisation and internationalisation of educational tourism, factors influencing educational tourists’ decision-making process and key elements influencing educational tourists’ decisions in HE institutions. At the end of the chapter, a case study is presented that reports the findings of interviews with educational tourists, overseas recruitment agents and Eastern Mediterranean University staff responsible for promoting the institution. The results identified eight factors affecting educational tourists’ decisions on study destination. Those factors comprise cost, ease of access, location, social factors, quality of education, instruction language, cultural environment and communication quality. The sub-factors of the main eight factors are scholarships, destination’s scenery, safety, friends’ and relatives’ influence and cultural differences. This chapter brings a significant knowledge about the motives that affect educational tourists in selecting at a particular HE destination. Based on the study’s findings, educational institutions may consider various recommendations to redesign their strategies towards attracting educational tourists more effectively. Generally, this study promotes an apprehension about the diverse elements that affect educational tourists’ selection of a destination study. An in-depth understanding of these factors will help education institutions’ decision-makers better develop plans of action to provide desired services to educational tourists, attract and keep them in return.

Abstract

The advent of derivatives and structured products has coincided with a proliferation of fixed income models used to analyze hedging, pricing, forecasting, and estimation for the term structure of interest rates. This article evaluates five models Ho‐Lee (HL); Black‐Derman‐Toy (BDT); Vasicek; Cox‐Ingersoll‐Ross (CIR); and Heath‐Jarrow‐Morton (HJM) (see Exhibit 1) that are currently used by structured finance practitioners. We suggest which models are most appropriate for assets with different time horizons, interest rate sensitivities and cashflow properties. The authors link model selection to structured financial instruments with the singular focus on the trade‐off between model precision/complexity and calculation costs.

Abstract

Answering to calls for further contextualizing global leadership, this study investigates power dynamics and cultural identities in global leadership in an African context. We took a grounded theory approach to investigate how a specific cultural context shapes assets and liabilities of global leaders. Drawing on our data comprising semi-structured interviews of managers of multinational enterprises operating in Ghana, we identified key assets and liabilities for being local or foreign in one’s global leadership role. Furthermore, we theorize four specific styles of leadership leveraging: identity leveraging, power leveraging, juxtapositional leveraging, and temporal leveraging. Finally, we integrated the above-mentioned elements and proposed a framework of contextualized assets and liabilities which illustrates how specific cultural context affects the assets and liabilities of localness and foreignness for global leaders, and how these assets and liabilities constitute the four styles of leveraging in such context. Implications of our findings for research and practice are discussed.

Abstract

Purpose

The model for digitally controlled three-phase pulse width modulation (PWM) boost rectifiers is a sampled data model, which is different from the continuous time domain models presented in previous studies. The controller, which is tuned according to the model in continuous time domain and discretized by approximation methods, may exhibit some unpredictable performances and even result in unstable systems under some extreme situations. Consequently, a small-signal discrete-time model of digitally controlled three-phase PWM boost rectifier is required. The purpose of this paper is to provide a simple but accurate small-signal discrete-time model of digital controlled three-phase PWM boost rectifier, which explains the effect of the sampling period, modulator and time delays on system dynamic and improves the control performance.

Design/methodology/approach

Based on the Laplace domain analysis and the waveforms of up-down-count modulator, the small signal model of digital pulse width modulation (DPWM) in the Laplace domain is presented. With a combination of state-space average and a discrete-time modeling technique, a simplified large signal discrete time model is developed. With rotation transformation and feed-forward decoupling, the large-signal model is decoupled into a single input single output system with rotation transformation. Then, an integrated small signal model in the Laplace domain is constructed that included the time delay and modulation effect. Implementing the modified z-transform, a small-signal discrete-time model is derived from the integrated small signal model.

Findings

In a digital control system, besides the circuit parameters, the location of pole of open-loop transfer function is also related to system sampling time, affecting the system stability, and the time delay determines the location of the zero of open-loop transfer function, affecting the system dynamic. In addition to the circuit parameters discussed in previous literature, the right half plane (RHP) zero is also determined by the sampling period and the time delay. Furthermore, the corner frequency of the RHP zero is mainly determined by the sampling period.

Originality/value

The model developed in this paper, accounting for the effect of the sampling period, modulator and time delays on the system dynamic, give a sufficient insight into the behavior of the digitally controlled three-phase PWM rectifier. It can also explain the effect of sampling period and control delay time on system dynamic, accurately predict the system stability boundary and determine the oscillation frequency of the current loop in critical stable. The experimental results verify that the model is a simple and accurate control-oriented small-signal discrete-time model for the digitally controlled three-phase PWM boost rectifier.

Abstract

Mixed recirculatory flow in the annuli of stationary and rotating horizontal cylinders were studied numerically. A set of distorted ‘false transient’ parameters were introduced to speed up the steady state solution of the unsteady vorticity, energy and stream function—vorticity equations. The inner cylinder of the annuli is assumed heated and rotating at Reynolds numbers that exclude the effects of centrifugal acceleration and three‐dimensional Taylor vortices. The Prandtl number considered is in the range of 0.01 to 1.0 and Rayleigh number in the range of 102 to 106. Radius ratios of the cylinders considered are 1.25, 2.5 and 5.0. For a radius ratio of 2.5, inner cylinder rotation in the Reynolds number range of 0 to 1120 was considered. Vertical eccentricities in the range of ±2/3 were studied for cases of the rotating inner cylinder. Numerical experiments show that the mean Nusselt number increases with Rayleigh number for both cases of concentric and eccentric stationary inner cylinder. At a Prandtl number of order 1.0 with a fixed Rayleigh number, when the inner cylinder is made to rotate, the mean Nusselt number decreases throughout the flow. At lower Prandtl number of the order 0.1 to 0.01, the mean Nusselt number remained fairly constant with respect to the rotational Reynolds number.
