Overcoming analytical reliability issues in clinical proteomics using rank-based network approaches
Authors: Bin Goh Wilson Wen , Wong Limsoon 
Published: June 2015

AbstractProteomics is poised to play critical roles in clinical research. However, due to limited coverage and high noise, integration with powerful analysis algorithms is necessary. In particular, network-based algorithms can improve selection of reproducible features in spite of incomplete proteome coverage, technical inconsistency or high inter-sample variability. We define analytical reliability on three benchmarks --- precision/recall rates, feature-selection stability and cross-validation accuracy. Using these, we demonstrate the insufficiencies of commonly used Student’s t-test and Hypergeometric enrichment. Given advances in sample sizes, quantitation accuracy and coverage, we are now able to introduce and evaluate Ranked-Based Network Approaches (RBNAs) for the first time in proteomics. These include SNET (SubNETwork), FSNET (FuzzySNET), PFSNET (PairedFSNET). We also introduce for the first time, PPFSNET(samplePairedPFSNET), which is a paired-sample variant of PFSNET. RBNAs (particularly PFSNET and PPFSNET) excelled on all three benchmarks and can make consistent and reproducible predictions even in the small-sample size scenario (n=4). Given these qualities, RBNAs represent an important advancement in network biology, and is expected to see practical usage, particularly in clinical biomarker and drug target prediction.

Authors: Balakrishnan Melodena Stephens , Moonesar Immanuel Azaad 
Published: June 2015

Subject area
Health Management and Leadership, Marketing Social Causes, Strategy, International Business.

Study level/applicability
Post-graduates, Practitioners.

Case overview
General Electric has been operating in the Middle East, North Africa (MENA) region for over a century. GE is committed to corporate citizenship having launched ecomagination in 2005 and healthymagination in 2009. For sustainability, GE believes that both innovation and localization are critical. This case deals with contextualization of breast cancer campaign for the Kingdom of Saudi Arabia through healthymagination. Rania Rostom, Communications Director, Middle East, North Africa and Turkey region, GE, reviews the campaign implemented and looks at roll-out across the MENA region. The situation is unique, as breast cancer strikes women in the region ten years earlier than the West, and the cultural context does not allow the discussion of the topic in public. One of the peculiarities of this region was the high penetration of social media and its large adoption rate by the young. GE used a unique Facebook campaign to drive awareness on the topic, encourage screening appointments, seek treatment and reduce the discomfort associated with the process.

Published: June 2015

Subject area
The case can be introduced in the information technology (IT) strategy course. The case can also fit well in courses like emergent technologies where the case forms the vehicle to show how cloud-based solutions can provide leverage to an organization.

Study level/applicability
The case is aligned more for management participants, for example, students who are enrolled in master's or executive program in management. Considering the master's program in management, the case can be introduced in the IT strategy course. The case can also fit well in courses like emergent technologies where the case forms the vehicle to show how cloud-based solutions can provide leverage to an organization. Assignment questions addressed below are designed from the perspective of teaching this case to a business student audience. The case could certainly be adjusted to fit the needs of students in more technical disciplines.

Case overview
Set in March 2009, Charan Padmaraju, the CTO of redBus was grappling with his companies IT infrastructure and scalability issues. He was considering cloud computing as a solution to all his worries. redBus was founded in August 2006 as a bus ticketing company in India. From INR 50 lakhs of gross bookings in their first financial year 2006-07 to an estimated INR 300 million in gross bookings in the financial year ending 2008-09, redBus had registered phenomenal growth. From selling 10 tickets a day, it now sold more than 4,000 tickets a day for more than 5,000 routes across 15 states in India. However, the IT infrastructure of redBus could not match up with their business needs and required frequent upgrades. Charan thought “The procurement of new servers, upgrading existing servers and most of the developer's time went into circumventing scaling issues which were not adding values to our core business.” He wondered “Can cloud computing be an answer to all my worries? “But what exactly is cloud computing? Will it solve my existing scalability issues? How reliable it is? Is it expensive? What is the time for deployment?”

Expected learning outcomes
To understand what is a business model; to appreciate the technical issues related to business expansion decisions; to explain the concepts behind cloud based solutions; and to demonstrate how adoption of the cloud solution can enable an organization to achieve competitive advantage.

GEZ petrol station: CVP analysis and spread sheet modelling for planning and decision making
Authors: Ku Ismail Ku Nor Izah , Wan Hussin Wan Nordin , Salleh Mat Supian 
Published: June 2015

Subject area
Management Accounting and Financial Modelling.

Study level/applicability
Undergraduate and post-graduated levels.

Case overview
Aiman, the Area Manager of GEZ Berhad, realised the importance for petrol station operators to have an understanding of fundamental management accounting concepts such as cost behaviour and cost–volume–profit (CVP) analysis. He also believed that the petrol station operators should be proficient in using Microsoft Excel functionality and able to construct “intelligent” financial model with extended sensitivity analysis. Being a manager responsible for training the petrol station operators, Aiman would like to introduce the CVP concepts and spreadsheet model-building process to the petrol station operators, to aid them in planning and decision making. To construct the Excel spreadsheet model, Aiman sought the assistance of Rizal, a university lecturer in accounting, who in turn gathered the relevant operational and financial data from Baron Service Station, a typical petrol station under GEZ stable. The model should be flexible enough to allow the petrol station operator to anticipate, for example: What will happen to overall profitability of the petrol station if the fuel prices go up? What is the minimum volume of fuel that needed to be sold to break even? How much extra profit can be generated if credit card sale is reduced? and Is it viable to install an automated teller machines (ATM) kiosk and incurring administrative charges from bank to lure more customers to visit the petrol station? As the petrol station sells multiple products (petrol, diesel and convenience goods), the owner is also interested to know which product lines are the most and least profitable. Thus, the model should be able to generate segmented income statement with appropriate allocation of the common fixed costs to the each of the products.

Expected learning - outcomes
The case discussion is intended to achieve the following learning outcomes: students are able to prepare a financial model which include a segmented contribution income statement based on the information on product mix; students are able to calculate the break-even point and distinguish between fixed and variable costs; students are able to differentiate between traceable fixed costs and common fixed costs; students are able to build a financial model that is sufficiently flexible to allow various what if analysis to be performed; and students are able to use what if analysis tools in Excel such as Goal Seek and Data Tables.

Higher educational institutes as learning organizations for employer branding
Authors: LENKA USHA , CHAWLA SANIYA 
Published: June 2015

Purpose– Contemporary organizations emphasize upon continuous learning to be able to face the environmental dynamism and further build a learning organization. The purpose of this paper is to reflect the conceptual framework of learning organization, integrating variables at individual, team, and organizational levels.Design/methodology/approach– The framework has been devised through the review of literature from 1950s to 2014 using the databases of EBSCO, Emerald, Proquest, Science Direct, and Scopus to ensure the reliability.Findings– The variables are resonant leadership style, knowledge management, intrapreneurship, total quality management (TQM), and supportive learning culture. Resonant leaders are emotionally intelligent leaders who evoke positive emotions among their subordinates through setting an example, ensuring mindfulness, hope, and compassion. Knowledge management is basically creating, transferring, maintaining, and organizing knowledge in organizational repositories. Intrapreneurship is the initiative and risk taken by the employees. TQM is a management practice that promotes total involvement, continuous improvement, and reflexive decisions taken by team members. Supportive learning culture pushes individuals toward a common goal, which is further facilitated, by open communication, affective and cognitive trust, and organic structure. These factors pose as enablers to foster continuous learning among employees. A learning organization, therefore, can establish a strong employer brand by enhancing employees’ emotional attachment and further aides’ attraction and retention of talent.Originality/value– So far, all these important variables have been ignored in the academic literature especially in the context of educational institutes as learning organizations. Also, there is a void in academic literature with respect to integrated model of learning organization. In this way, the paper tries to fill the gap by developing a conceptual framework of learning organization, followed by discussion and managerial implications.
What every leader ought to know about becoming a servant leader
Authors: Mertel Tina , Brill Carol 
Published: June 2015

Purpose
– Employees want to be supported to do their best work, but not every leader is comfortable or motivated to serve an employee’s “soft, emotional” needs. One key to help leaders become servant leaders is connecting serving others to their own values (even if “serving others” is not a value). Two assessments provided the framework for understanding this link between servant leadership attributes and the leader’s values. A case study demonstrates this link within a healthcare system where these tools helped develop servant leadership skills to support employee performance. The paper aims to discuss these issues.

Design/methodology/approach
– The authors used a servant leadership competency assessment and values assessment with leaders in a healthcare organization. By citing several leadership experts, and explaining how values relate to servant leadership behaviors, the authors offer a way to help leaders understand that anyone can improve their success with servant leadership.

Findings
– By offering two case studies of anonymous yet actual participants in the study the authors show how leaders gained insights they needed to change their habits in working with others.

Research limitations/implications
– The research results are from two distinct assessments. Researchers are encouraged to test the proposed propositions further with other similar assessments.

Practical implications
– The paper includes implications for the development of a leader’s servant leadership behaviors, which in turn supports employee engagement and organizational success.

Social implications
– In today’s age of mass technology, it has become a unique proposition to relate to others on the basis of serving their needs by relating to their values one-on-one. This paper inherently promotes in-person conversation with “soft” skills such as, listening, empathy, appreciation, and kindness.

Originality/value
– This paper fulfills an identified need to study how servant leadership behaviors can be improved by using a second tool focused on values.
Applying a Kansei engineering-based logistics service design approach to developing international express services
Authors: Chen Mu-Chen , Chang Kuo-Chien , Hsu Chia-Lin , Xiao Jia-Hau 
Published: June 2015

Purpose
– To obtain a competitive advantage in the logistics market, international express companies should design services to stimulate customers’ usage intention by understanding customers’ affective perceptions (or in Japanese, Kansei) of the service offerings. Thus, the purpose of this paper is to analyze the relationships among the service elements of international express, customer Kansei perceptions, and intentions to use the service, to provide new ideas for the design of international express services (IESs).

Design/methodology/approach
– By using Kansei engineering approach, customers’ Kansei perceptions related to elements of IES are first determined, and the logistic regression technique is then used to analyze three constructed models based on the relationships among the service elements of international express, customers’ Kansei perceptions, and usage intention.

Findings
– Accordingly, five critical service elements that correspond to four vital Kansei words related to usage intention were obtained based on cross-comparisons of the results of three models. The findings have important implications for international express managers, in that the priorities in designing services should be those service elements that favorably elicit certain Kansei perceptions among customers and effectively lead to customers’ usage intention in the pre-purchase phase. Moreover, some important missing Kansei perceptions further derived from customers’ real service experiences in the post-purchase stage should be incorporated into future design considerations.

Originality/value
– This study incorporated customers’ Kansei perceptions into the procedure of IES design. By understanding the service elements and feelings that customers deem important, international express companies can improve the content of existing services and strengthen the design of new services to increase customers’ behavioral intentions.
Principal instructional leadership in Taiwan: lessons from two decades of research
Authors: Pan Hui-Ling Wendy , Nyeu Fong-Yee , Chen June S. 
Published: June 2015

Purpose
– The purpose of this paper is to examine how instructional leadership, a concept imported from Western scholarship, has been conceptualized in the Taiwanese context and how principal instructional leadership is realized in schools. The development trajectory of principal instructional leadership is delineated by examining empirical studies in the past two decades.

Design/methodology/approach
– This paper adopts an exploratory approach to review the Taiwanese empirical literature on principal instructional leadership. A total of 80 studies were systematically analyzed and common themes were identified.

Findings
– This paper finds that a hybrid model of the conceptualization of instructional leadership has been developed in Taiwan. Principals performed more indirect than direct leadership behaviors. A gap exists between the ideal instructional leader and the reality.

Research limitations/implications
– The development of a formal theory of instructional leadership is expected as various substantive theories are developed and more data are accumulated. To yield the desired outcome of knowledge acceleration, the coordination of research efforts across scholars and institutions is a must.

Practical implications
– The articles reviewed suggest less effort spent by principals on the teachers. Yet with a national promotion of teacher learning community, as well as cooperative and collaborative learning in recent years, principal instructional leadership behaviors are expected to rise in terms of ensuring instruction quality and professional development.

Originality/value
– This paper is an attempt to accumulate knowledge about principal instructional leadership in Taiwan. It is a contribution to the exploration of indigenous perspectives and practices and the understanding and building of educational leadership in Asia.
Making sense of images of fact and fiction
Authors: Hallinger Philip , Walker Allan , Trung Gian Tu 
Published: June 2015

Purpose
– The purpose of this paper is to review both international and domestic (i.e. Vietnamese language) journal articles and graduate theses and dissertations on educational leadership in Vietnam. The review addresses two specific goals: first, to describe and critically assess the nature of the formal knowledge base on principal leadership in Vietnam, second, to synthesize findings from the existing literature on principal leadership in Vietnam.

Design/methodology/approach
– The paper employed a method for conducting systematic reviews of research. The authors conducted a detailed, exhaustive search for international and “local” papers from Vietnam, yielding 120 research sources. Information from these papers was extracted and evaluated prior to analysis. Data analysis included both quantitative description of the “review database” as well as critical synthesis of substantive findings.

Findings
– The review supports and extends an earlier review which found that the practice of educational leadership in Vietnam remains largely “invisible” to the international community of scholars. The review also yielded a highly critical assessment of research perspectives and methods used in the “local” Vietnamese studies which comprised the bulk of the authors’ database. Synthesis of substantive findings highlighted the manner by which organizational, political, and socio-cultural forces in the Vietnamese context shapes the practice of school leadership.

Research limitations/implications
– First, qualitative studies are recommended that seek to describe, in-depth, the enactment of leadership in the Vietnamese context. Second, broad-scale surveys of characteristics, attitudes, and beliefs of school leaders across Vietnam are warranted. Third, the authors encourage graduate students and scholars studying school leadership in Vietnam to undertake a new generation of theory-informed studies that connect with the global literature.

Practical implications
– Due to the relatively weak nature of the existing knowledge base, the authors were unable to identify specific implications for leadership practice. However, practical implications are identified for developing the research capacity needed to improve research quality in Vietnam’s universities.

Originality/value
– This review is the first systematic review of educational leadership and management conducted of the Vietnamese literature. Moreover, the authors suggest that the review is original in its comprehensive coverage of both the local and international literature on educational leadership in Vietnam.
