Voltage control strategy for an uncertain mobile robot
Authors: Mehdi Fateh Mohammad , Asghar Arab Ali 
Published: November 2014

Purpose
– The uncertainty and nonlinearity are the challenging problems for the control of a nonholonomic wheeled mobile robot. To overcome these problems, many valuable methods have been proposed by using two control loops namely the kinematic control and the torque control so far. In majority of the proposed approaches the dynamics of actuators is omitted for simplicity in the control design. This drawback degrades the control performance in high-velocity tracking control. On the other hand, to guarantee stability and overcome uncertainties, the control methods become computationally extensive and may be impractical due to using all states. The purpose of this paper is to design a simple controller with guaranteed stability for overcoming the nonlinearity, uncertainty and actuator dynamics.

Design/methodology/approach
– The control design includes two control loops, the kinematic control loop and the novel dynamic control loop. The dynamic control loop uses the voltage control strategy instead of the torque control strategy. Feedbacks of the robot orientation, robot position, robot linear and angular velocity, and motor currents are given to the control system.

Findings
– To improve the precision, the dynamics of motors are taken into account. The most important advantages of the proposed control law is that it is free from the robot dynamics, thereby the controller is simple, fast response and robust with ignorable tracking error. The control approach is verified by stability analysis. Simulation results show the effectiveness of the proposed control applied on an uncertain nonholonomic wheeled mobile robot driven by permanent magnet dc motors. A comparison with an adaptive sliding-mode dynamic control approach confirms the superiority of the proposed approach in terms of precision, simplicity of design and computations.

Originality/value
– The originality of the paper is to present a new control design for an uncertain nonholonomic wheeled mobile robot by using voltage control strategy in replace of the torque control strategy. In addition, a novel state-space model of electrically driven nonholonomic wheeled mobile robot in the workspace is presented.
Vehicle identification by improved stacking via kernel principal component regression
Authors: Zhang Bailing , Pan Hao 
Published: November 2014

Purpose
– Many applications in intelligent transportation demand accurate categorization of vehicles. The purpose of this paper is to propose a working image-based vehicle classification system. The first component vehicle detection is implemented by applying Dalal and Triggs's histograms of oriented gradients features and linear support vector machine (SVM) classifier. The second component vehicle classification, which is the emphasis of this paper, is accomplished by an improved stacked generalization. As an effective ensemble learning strategy, stacked generalization has been proposed to combine multiple models using the concept of a meta-learner. However, it was found that the well-known meta-learning scheme multi-response linear regression (MLR) for stacked generalization performs poorly on the vehicle classification.

Design/methodology/approach
– A new meta-learner is then proposed based on kernel principal component regression (KPCR). The stacked generalization scheme consists of a heterogeneous classifier ensemble with seven base classifiers, i.e. linear discriminant classifier, fuzzy k-nearest neighbor, logistic regression, Parzen classifier, Gaussian mixture model, multiple layer perceptron and SVM.

Findings
– Experimental results using more than 2,500 images from four types of vehicles (bus, light truck, car and van) demonstrated the effectiveness of the proposed approach. The improved stacked generalization produced consistently better results when compared to any of the single base classifier used and four other beta learning algorithms, including MLR, majority voting, logistic regression and decision template.

Originality/value
– With the seven base classifiers, the KPCR-based stacking offers a performance of 96 percent accuracy and 95 percent κ coefficient, thus exhibiting promising potentials for real-world applications.

Authors: Ameni Ellouze , Ksantini Mohamed , Lauber Jimmy , Delmotte François , Chtourou Mohamed 
Published: November 2014

Purpose– The purpose of this paper is to deal with the stabilization of the continuous-time Takagi-Sugeno (TS) fuzzy models by using their discretized models.Design/methodology/approach– In this case, a discrete model is obtained from the discretization of the continuous TS fuzzy model. The gains obtained from a non-parallel distributed compensation controller ensuring the stabilization of the discrete model are used to check if the discrete control law used in the continuous time without any zero-order hold can stabilize the continuous TS model.Findings– This method is compared to another published method.Originality/value– Therefore, the originality of this paper consists in the fusion of the two continuous and discrete cases to obtain new stabilization conditions in the continuous case. Simulation examples show the interest of the proposed approach.
Supervisor or counsellor? – Emotional boundary work in supervision
Authors: Strandler Ola , Johansson Thomas , Wisker Gina , Claesson Silwa 
Published: November 2014

Purpose– The aim of this article was to focus on how supervisors relate to and handle the emotional work involved in the supervision process. These emotional issues are related to changes in the academic system, such as an increasing emphasis on efficacy and quality assurance.Design/methodology/approach– Interviews with supervisors are discussed using a theoretical framework built on the concepts of emotional boundary work and feeling rules. A narrative approach was used to make connections between individual stories and the institutional level of the academic system.Findings– The findings show how emotions challenge and condition supervision, and how the micro-processes of supervision and the wider university systems are tightly connected. A paradox is illuminated where emotional aspects are both recognized as an important feature of supervision and as a threat, which could affect it in the context of regulation and increasing demands on efficiency.Practical implications– The findings suggest that a mediating role of supervisors and emotional boundary work needs to be considered in supervision, which demands certain amount of flexibility in regulations. Also, the risks of associating supervision with private issues are acknowledged.Originality/value– The findings suggest that supervision is a highly emotional process, and that supervisors, on the one hand, tend to downplay the emotional side of this process, but on the other hand, are well aware of the complexity of the supervision process and its demands on them. Although supervisor–student interactions have become more regulated, they also include more attention to human interactions, feelings and emotional boundary work.
Mentor-protégé fit
Authors: L. Baker Vicki , J. Pifer Meghan , A. Griffin Kimberly 
Published: November 2014

Purpose– The aim of this conceptual paper is to explore Mentor-protégé fit as important to the selection and development of successful doctoral student–faculty mentoring relationships. We suggest that the student–faculty relationship in doctoral education is an additional and previously untested type of Mentor-protégé fit.Design/methodology/approach– Generated from an existing framework of identity in the academy, we explore how three types of identity (professional, relational, personal) may influence students’ fit assessments as they seek to initiate and develop relationships.Findings– We offer propositions for research to further explore the potential application of the proposed framework to knowledge generation about the doctoral student experience.Originality/value– While the research about doctoral education has considered all three aspects of students’ identities individually, it has not explicated the ways in which these intersecting identities relate to students’ needs and expectations related to mentoring, their choices related to mentor selection, or the effectiveness and outcomes of mentoring relationships in fostering success and satisfaction.
Young people online and the social value of privacy
Authors: Steeves Valerie , Regan Priscilla 
Published: November 2014

Purpose– The purpose of this paper is to develop a conceptual framework to contextualize young people’s lived experiences of privacy and invasion online. Social negotiations in the construction of privacy boundaries are theorized to be dependent on individual preferences, abilities and context-dependent social meanings.Design/methodology/approach– Empirical findings of three related Ottawa-based studies dealing with young people’s online privacy are used to examine the benefits of online publicity, what online privacy means to young people and the social importance of privacy. Earlier philosophical discussions of privacy and identity, as well as current scholarship, are drawn on to suggest that privacy is an inherently social practice that enables social actors to navigate the boundary between self/other and between being closed/open to social interaction.Findings– Four understandings of privacy’s value are developed in concordance with recent privacy literature and our own empirical data: privacy as contextual, relational, performative and dialectical.Social implications– A more holistic approach is necessary to understand young people’s privacy negotiations. Adopting such an approach can help re-establish an ability to address the ways in which privacy boundaries are negotiated and to challenge surveillance schemes and their social consequences.Originality/value– Findings imply that privacy policy should focus on creating conditions that support negotiations that are transparent and equitable. Additionally, policy-makers must begin to critically evaluate the ways in which surveillance interferes with the developmental need of young people to build relationships of trust with each other and also with adults.
Perceptions of ethics in IS: how age can affect awareness
Authors: Helen Wilford Sara , Jacqueline Wakunuma Kutoma 
Published: November 2014

Purpose
– This aim of this paper was to highlight the awareness of ethical issues across the group of information systems (IS) professionals from a range of geographical regions.

Design/methodology/approach
– An initial survey was conducted that informed in-depth interviews with 26 IS professionals from across the globe. The study identified that around 70 per cent of the sample were over 50 years old. This provided an opportunity to consider age-related differences in perception regarding ethical awareness of both current and emerging technologies.

Findings
– The project revealed that the more mature IS professionals had a significantly higher level of awareness and perceived understanding regarding the importance of ethical issues than the younger IS professionals.

Research limitations/implications
– The research was limited to IS professionals and so the findings do not generalise further. Future research would be beneficial to find out if the higher level of ethical awareness is also evident across older people in general or whether it is specific to technology professionals.

Practical implications
– IS professionals need to be exposed to high standards and expectations of ethical behaviour from senior colleagues, as well as embedding this within technical education.

Social implications
– Caution with regards to youth culture and youthitisation of the workforce needs to be exerted to avoid rash decision-making and short-termism, which could undermine progress and development. A change in the view of employers to older workers will also require a change in attitudes across Western society, particularly as demographics continue to skew towards an aging population.

Originality/value
– This paper provides new insight into the ethical awareness of older employees and goes some way to dispel the myths surrounding stereotypes of older workers as being fearful of technology and resistant to change.

Published: November 2014

Purpose– The purpose of this paper is to review the digital piracy literature and present the positive impacts of digital piracy and its benefit to businesses. A great deal of the literature discusses the consequences of digital piracy, but, in most cases, the focus is on the negative consequences.Design/methodology/approach– The authors draw on both the theoretical and empirical academic literature on digital piracy so as to analyze the ways in which digital piracy positively contributes to digital businesses.Findings– The paper provides information on the positive consequences of digital piracy and demonstrates that the benefits include product diffusion, network externality, innovation, cost reduction, an effective promotional and publicity vehicle, and technology standardization.Originality/value– This paper investigates potential benefits of digital piracy and provides insights which may offer a fuller picture of the consequences of digital piracy.
Cross promotion of web references in print ads
Authors: Lepkowska-White Elzbieta , Parsons Amy , Ceylan Aylin 
Published: November 2014

Purpose
– This paper aims to examine whether advertisers attempt to engage consumers with online information presented in print advertisements by investigating whether they respond to consumers’ motives for using advertisements and whether these engagement practices have improved over time. By creating connections among different advertising channels, marketers strive to be more effective in building brand equity, online traffic and sales.

Design/methodology/approach
– The Uses and Gratification theory is utilized as the framework to content analyze the content and presentation of web references in 2,613 advertisements from 2008 and 2,159 advertisements from 2012. Chi-square analysis is used to compare the content of web references in both time periods.

Findings
– Even though past literature suggests that consumers use media and advertising to satisfy a variety of informational, personal identity, social and entertainment needs, advertisers respond with mostly ineffective and generic informational web references that fail to address those needs.

Research limitations/implications
– The study suggests that advertisers may have difficulty adopting the new advertising paradigm which identifies customers as active respondents of advertising. Web references analyzed in this study do not address consumers’ motives for advertisement use.

Practical implications
– Advertisers have not been effectively utilizing cross-promotion when it comes to directing traffic from print advertisements to Web sites. More attention and resources should be given to cross-promotion to ensure effective coordination between media types.

Originality/value
– This study questions advertisers’ current approach toward cross-promotion. Findings help advertisers evaluate and develop better practices to encourage consumer engagement with web references placed in print advertisements to drive traffic to online stores.

Authors: Rodriguez Michael , L. Dixon Andrea , W. Peltier James 
Published: November 2014

Purpose
– The purpose of this 16-year review is to summarize interactive marketing literature in the context of personal selling and sales management. This paper serves as precursor to the Special Issue on the Convergence of Interactive Marketing and Personal Selling and Sales Management to be published by the Journal of Research in Interactive Marketing. Key research needs are identified.

Design/methodology/approach
– A content analysis was performed on 106 articles categorized over 1998-2013. Ebsco Host was used as the database search engine, running impendent searches using personal selling, professional selling and sales management as identifiers across a variety of interactive marketing topics identified by Journal of Research in Interactive Marketing (JRIM)’s Editorial Board.

Findings
– The examination of the convergence of interactive marketing in a personal selling/sales management context revealed 106 articles, with approximately 60 per cent being published in the past eight years. Although the interactive marking field is growing, there is clearly a significant opportunity for scholarly work across wide-ranging personal selling and sales management topics, and specifically in the areas of performance indices, evolving technologies, social media and tactical sales and management issues.

Practical implications
– The paper reviews personal selling and sales management articles that have been published in the time period of 1998-2013 across marketing, business and non-business journals. While the Journal of Personal Selling and Sales Management has been the dominant outlet, other marketing and non-marketing journals are increasing their exposure in these areas.

Originality/value
– The study provides both academics and practitioners with an updated review of the interactive marketing literature along with a sense of how personal selling and sales management research is evolving. This review offers value as a standalone article and as input for scholars submitting manuscripts to JRIM’s Special Issue on the Convergence of Interactive Marketing and Personal Selling and Sales Management.
Student satisfaction toward e-textbooks in higher education
Authors: Hao Yungwei , Jackson Kathy 
Published: November 2014

Purpose
– This study aims to add to the body of literature by examining students’ satisfaction with e-textbooks. As higher education evolves, one instructional tool, the classic textbook, is undergoing various transformations. In today’s classrooms, many e-textbooks are in use and there are implications.

Design/methodology/approach
– A researcher-developed instrument measured 115 undergraduate students’ satisfaction levels for e-textbooks used in two courses, and a learning styles instrument was given to identify student learning preferences.

Findings
– Through factor analysis, a few dimensions emerged regarding factors related to satisfaction. The factors included features, usability and learning facilitation provided by the e-textbooks. In general, students had a moderately above-neutral, positive attitude toward the e-textbooks. Gender, grade point average, time spent weekly reading e-textbooks and a few learning style tendencies can significantly predict, to some extent, different dimensions of satisfaction.

Practical implications
– Usability design of e-textbooks plays a key role in student satisfaction toward digital materials. Moreover, instructors need to use meaningful instructional activities as they adopt the usage of e-textbooks.

Originality/value
– The findings can help shed light on ways to enable students to become more satisfied with digital textbooks and can help policymakers and instructors evaluate and effectively adopt the appropriate digital materials to meet individual needs.
