Abstract

Purpose

This research seeks to understand whether employer branding (EB) and internal marketing (IM) are fundamental to the challenge of attracting and retaining talent and how these strategies can help companies to overcome the difficulties related to the talent shortage, from the perspective of a SME Portuguese metallurgical industry.

Design/methodology/approach

The research resorts to a case study of a qualitative nature, through a semi-structured interview with the head of the human resources (HR) training and development area of the Navarra Group, and quantitative, through surveys to its employees. Based on the literature, a conceptual model was constructed, whose application allowed us to perceive the relationships between the practices of EB and IM; satisfaction, motivation and commitment; attraction and retention.

Findings

The exploratory interview concluded that organizations consider EB and IM essential for an effective talent management strategy. The quantitative results demonstrate that IM and EB practices implemented in the organization contribute to the satisfaction, motivation and involvement of employees, which results in a decrease in the intention to leave. It is also noted that these practices promote an increase in the perception of organizational attractiveness, which represents a positive impact on its ability to attract.

Research limitations/implications

From a theoretical perspective, the research contributes to the development of knowledge about IM, EB and talent management, providing relevant data that can help define the best strategies for attraction and retention, from the point of view of IM and EB.

Originality/value

The research presents preliminary insights that can be an auxiliary tool for HR managers and professionals in the context of industrial SMEs.

Abstract

Purpose

The lack of conceptual approaches for organizing and expressing capabilities, usage and impact of intelligent machines (IMs) in work settings is an obstacle to moving beyond isolated case examples, domain-specific studies, 2 × 2 frameworks and expert opinion in discussions of IMs and work. This paper's purpose is to illuminate many issues that often are not addressed directly in research, practice or punditry related to IMs. It pursues that purpose by presenting an integrated approach for identifying and organizing important aspects of analysis and evaluation related to IMs in work settings. 

Design/methodology/approach

This paper integrates previously published ideas related to work systems (WSs), smart devices and systems, facets of work, roles and responsibilities of information systems, interactions between people and machines and a range of criteria for evaluating system performance.

Findings

Eight principles outline a straightforward and flexible approach for analyzing and evaluating IMs and the WSs that use them. Those principles are based on the above ideas.

Originality/value

This paper provides a novel approach for identifying design choices for situated use of IMs. The breadth, depth and integration of this approach address a gap in existing literature, which rarely aspires to this paper’s thoroughness in combining ideas that support the description, analysis, design and evaluation of situated uses of IMs.

Abstract

Purpose

The purpose of this article is to treat the nonlinear optimal control problem in EV traction systems which are based on 5-phase induction motors. Five-phase permanent magnet synchronous motors and five-phase asynchronous induction motors (IMs) are among the types of multiphase motors one can consider for the traction system of electric vehicles (EVs). By distributing the required power in a large number of phases, the power load of each individual phase is reduced. The cumulative rates of power in multiphase machines can be raised without stressing the connected converters. Multiphase motors are also fault tolerant because such machines remain functional even if failures affect certain phases.

Design/methodology/approach

A novel nonlinear optimal control approach has been developed for five-phase IMs. The dynamic model of the five-phase IM undergoes approximate linearization using Taylor series expansion and the computation of the associated Jacobian matrices. The linearization takes place at each sampling instance. For the linearized model of the motor, an H-infinity feedback controller is designed. This controller achieves the solution of the optimal control problem under model uncertainty and disturbances.

Findings

To select the feedback gains of the nonlinear optimal (H-infinity) controller, an algebraic Riccati equation has to be solved repetitively at each time-step of the control method. The global stability properties of the control loop are demonstrated through Lyapunov analysis. Under moderate conditions, the global asymptotic stability properties of the control scheme are proven. The proposed nonlinear optimal control method achieves fast and accurate tracking of reference setpoints under moderate variations of the control inputs.

Research limitations/implications

Comparing to other nonlinear control methods that one could have considered for five-phase IMs, the presented nonlinear optimal (H-infinity) control approach avoids complicated state-space model transformations, is of proven global stability and its use does not require the model of the motor to be brought into a specific state-space form. The nonlinear optimal control method has clear implementation stages and moderate computational effort.

Practical implications

In the transportation sector, there is progressive transition to EVs. The use of five-phase IMs in EVs exhibits specific advantages, by achieving a more balanced distribution of power in the multiple phases of the motor and by providing fault tolerance. The study’s nonlinear optimal control method for five-phase IMs enables high performance for such motors and their efficient use in the traction system of EVs.

Social implications

Nonlinear optimal control for five-phase IMs supports the deployment of their use in EVs. Therefore, it contributes to the net-zero objective that aims at eliminating the emission of harmful exhaust gases coming from human activities. Most known manufacturers of vehicles have shifted to the production of all-electric cars. The study’s findings can optimize the traction system of EVs thus also contributing to the growth of the EV industry.

Originality/value

The proposed nonlinear optimal control method is novel comparing to past attempts for solving the optimal control problem for nonlinear dynamical systems. It uses a novel approach for selecting the linearization points and a new Riccati equation for computing the feedback gains of the controller. The nonlinear optimal control method is applicable to a wider class of dynamical systems than approaches based on the solution of state-dependent Riccati equations.

Abstract

Purpose

New technologies have provided new tools we may use as finance professors to communicate with our students. Instant messaging (IM) has become a common communication tool in industry and among students. The purpose of this paper is to investigate the use of IM as a communication tool in finance courses.

Design/methodology/approach

After reviewing the advantages and disadvantages of IM, the students were surveyed to determine how they viewed IM in comparison to other communication techniques.

Findings

The paper finds that 50 per cent or students use IM at any time (not just for class). The majority of the IM users, use it several times a day and have used it for two to three years. Only about 15.7 per cent of our students have used IM for our classes. The range of IM usage in the classes is 7‐25 per cent. Of those students who have used IM for our courses, they have used it 2‐5 times during the semester and almost all students found it useful. Students were asked to rate various methods of professor/student communication. The students strongly like face‐to‐face communication, followed by (in order of preference) email, IM, and telephone. Students disagree with the statement that IM is a substitute for face‐to‐face interaction and agree that IM is a supplement to face‐to‐face interaction.

Originality/value

The findings suggest ways to improve communications with students and other persons.

Abstract

Purpose

The purpose of this paper is to make a quantitative comparison between induction machine (IM) and interior permanent magnet machine (IPM) for electric vehicle applications, in terms of electromagnetic performance and material cost.

Design/methodology/approach

The analysis of IM is based on an analytical method, which has been validated by test. The analysis of IPM is based on finite element analysis. The popular Toyota Prius 2010 IPM is adopted directly, and the IM is designed with the same stator outer diameter and stack length as Prius 2010 IPM for a fair comparison.

Findings

The torque capability of IM is lower than IPM for low electric loading and competitive to IPM for high electric loading. The maximum torque/power-speed characteristic of IM is competitive to IPM; while the rated torque/power-speed characteristic of IM is poorer than IPM. The power factor of IM is competitive and even better than IPM for high electric loading in low-speed region. The torque ripple of IM is comparable to IPM for high electric loading and much lower than IPM for low electric loading. The overall efficiency of IM is lower than IPM, and the maximum efficiency of copper squirrel cage IM is approximately 2-3 percent lower than IPM. The material cost of IM is about half of IPM when IM and IPM are designed with the same stator outer diameter and stack length.

Originality/value

The electromagnetic performances and material costs of IM and IPM are quantitatively compared and discussed.

Abstract

Purpose

The purpose of this paper is to provide guidelines for entrepreneurs for implementing effective inventory management (IM) practices and presents the results of a survey of machine tool enterprises in Bangalore, India.

Design/methodology/approach

A descriptive analysis is used to present aspects of the findings, which reflect the current state of IM in machine tool enterprises. In addition, percentages, bar diagrams and correlation analysis provide a more accurate assessment of this industry sector.

Findings

The study identified several major problems in the context of IM in machine tool enterprises including the use of rule‐of‐thumb for IM, a low importance given to forecasting, random ordering of materials, low levels of training and development, and low computer use as well as a low importance given to purchasing and variable lead‐time. The study confirmed the need for managers in the machine tool sector to alter drastically their approach to IM.

Research limitations/implications

This study of 40 SMEs in Bangalore should be extended using a larger sample representative of Indian SMEs in order to arrive at findings that are more generalizable across the machine tool sector in India.

Practical implications

The managers of SMEs should consider seriously IM as a strategic concept simply because effective IM positively influences productivity. There is profound scope for improving the operations and performance of SMEs through the application of quality practices in IM.

Originality/value

Considering the lack of studies about IM in the context of Indian small and medium sized enterprises (SMEs), this paper helps fill a gap in the literature. A review of the policy framework concerned with SMEs suggests that policymakers do not consider critically the role of IM and related issues. It is significant to note that there is no exclusive reference to improvement in IM within the policy documents. At the same time, the literature review suggests that effective approaches to IM can improve the productivity and competitiveness of SMEs.
