Does institutional investors’ monitoring substitute for litigation in curbing insider trading? The case of Malaysia
Authors: Wasiuzzaman Shaista , Lim Kean Hua 
Published: January 2017

Purpose
The ineffectiveness of external governance mechanisms (laws and regulations) designed to curb insider trading in Malaysia leads this study to focus on the role of internal governance of firms in helping to reduce insider trading incidences. The purpose of this paper is to investigate the influence on institutional shareholders on insider trading activity.

Design/methodology/approach
The study uses data collected from a sample of 115 firms listed on the Bursa Malaysia over a five-year period (from year 2010 to 2014). Ordinary least squares technique is used to achieve the objective of this study.

Findings
The findings of this study points toward asymmetric information as a motivator for insider trading activity. Unlike previous studies which find the presence of institutional investors helping to reduce insider trading, this study finds results to the contrary.

Originality/value
This study focuses on the influence of institutional shareholdings on insider trading. The results provide more insight into the effectiveness of the role of institutions in curbing insider trading and suggest a closer monitoring of institutional shareholders.
A review of the most important failure, reliability and nonlinearity aspects in the development of microelectromechanical systems (MEMS)
Authors: Rafiee Peyman , Khatibi Golta , Zehetbauer Michael 
Published: January 2017

PurposeThe purpose of this paper is to provide an overview of the major reliability issues of microelectromechanical systems (MEMS) under mechanical and environmental loading conditions. Furthermore, a comprehensive study on the nonlinear behavior of silicon MEMS devices is presented and different aspects of this phenomenon are discussed.Design/methodology/approachRegarding the reliability investigations, the most important failure aspects affecting the proper operation of the MEMS components with focus on those caused by environmental and mechanical loads are reviewed. These studies include failures due to fatigue loads, mechanical vibration, mechanical shock, humidity, temperature and particulate contamination. In addition, the influence of squeeze film air damping on the dynamic response of MEMS devices is briefly discussed. A further subject of this paper is discussion of studies on the nonlinearity of silicon MEMS. For this purpose, after a description of the basic principles of nonlinearity, the consequences of nonlinear phenomena such as frequency shift, hysteresis and harmonic generation and their effects on the device performance are reviewed. Special attention is paid to the mode coupling effect between the resonant modes as a result of energy transfer because of the nonlinearity of silicon. For a better understanding of these effects, the nonlinear behavior of silicon is demonstrated by using the example of Si cantilever beams.FindingsIt is shown that environmental and mechanical loads can influence on proper operation of the MEMS components and lead to early fracture. In addition, it is demonstrated that nonlinearity modifies dynamic response and leads to new phenomena such as frequency shift and mode coupling. Finally, some ideas are given as possible future areas of research works.Originality/valueThis is a review paper and aimed to review the latest manuscripts published in the field of reliability and nonlinearity of the MEMS structures.

Authors: Manjakkal Libu , Packia Selvam I. , Potty S.N. , Shinde R.S. 
Published: January 2017

Purpose
Aluminium-doped zinc oxide thin films exhibit interesting optoelectronic properties, which make them suitable for fabrication of photovoltaic cell, flat panel display electrode, etc. It has been shown that aluminium dopant concentration and annealing treatment in reduced atmosphere are the major factors affecting the electrical and optical properties of aluminium doped zinc oxide (AZO) film. Here, the authors report the structural, optical and electrical properties of aluminium-doped zinc oxide thin films fabricated by dip coating technique and annealed in air atmosphere, thereby avoiding hazardous environments such as hydrogen. The aim of this paper was to systematically investigate the effect of annealing temperature on the electrical properties of dip-coated film.

Design/methodology/approach
Aluminium-doped ZnO thin films were prepared on corning substrates by dip coating method. Aluminium concentration in the film varied from 0.8 to 1.4 mol per cent. Films have been characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, UV-visible spectroscopy and Hall measurements. The deposited films were heat treated at 450-600°C, in steps of 50°C for 1 h in air to study the improvement in electrical properties. Films were also prepared by annealing at 600°C in air for durations of 1, 2, 4 and 6 h. Envelope method was used to calculate the variation of the refractive index and extinction coefficient with wavelength.

Findings
The electrical resistivity is found to decrease considerably when the annealing time is increased from 1 to 4 h. The films exhibited high transmittance (>90 per cent) in the visible range, and the optical band gaps were found to change as per the Moss–Burstien effect, and this was consistent with the observed changes in the carrier concentration.

Originality/value
The study shows the effect of annealing in air, avoiding hazardous reduced environment, such as hydrogen, to study the improvement in electrical and optical properties of aluminum-doped zinc oxide films. Envelope method was used to calculate the variation of optical constants with wavelength.
Hot-point probe measurements of N-type and P-type ZnO films
Authors: Au Benedict Wen-Cheun , Chan Kah-Yoong , Sin Yew-Keong , Ng Zi-Neng 
Published: January 2017

Purpose
This paper aims to develop a low-cost hot-point which can facilitate the conductivity type of N-type and P-type zinc oxide (ZnO) films. In this study, a diode was made out of the N-type and P-type ZnO films, and current-voltage (I-V) characteristic measurements were conducted.

Design/methodology/approach
A low-cost hot-point probe consists of a soldering iron station, digital multimeter and a pair of probes. The setup is adopted to identify N-type and P-type ZnO films. In particular, P-type films have been deployed for the first time.

Findings
Hot-point probe setup has been successfully developed. Measurements of N-type films give a positive voltage reading, whereas P-type films give a negative voltage reading. The measured voltage dominates at 1 per cent for N-type Ga and at 15 per cent for P-type Na. I-V characteristics of the fabricated diode showed a similar trend to the conventional diode.

Research limitations/implications
N-type has been often attempted. However, P-type has rarely been attempted because of the self-compensation effect in ZnO. There is a need to verify the conductivity type of ZnO films, especially P-type, as P-type films are not stable. The hot-point probe setup serves as a quick means to verify P-type ZnO films.

Originality/value
To the best of the authors’ understanding, this verification tool was developed and deployed to verify the N-type and P-type ZnO films. The P-type films are coated on top of the N-type films for diode I-V measurements.
Accounting toward sweet success: Treadwell’s Ice Cream
Authors: Lam Miranda , Guo Hongtao , McGee Paul 
Published: January 2017

Synopsis
Tom Gould, an entrepreneur, had been operating Treadwell’s Ice Cream, a small ice cream restaurant since 2000. Treadwell’s Ice Cream had been preparing its financial statements under cash basis. Tom Gould turned over all his receipts, both personal and business expenses, to his bookkeeper who entered them into QuickBooks. At tax time, his tax accountant excluded non-qualifying expenses from the tax filing. Periodically, Tom met with his bookkeeper to determine the results of operations and financial position at the end of that period of time. Most of Treadwell’s transactions were easily recognized by Tom, who preferred to pay all expenses by cash rather than credit. However, the bookkeeper had not been separating operating from non-operating activities, and had been using multiple accounts to record the same or similar costs. Therefore, the current income statement and balance sheet were not appropriately categorized and organized. In addition, since the bookkeeper was not a tax account, business expenses had been mixed with Tom Gould’s personal expenses on the income statement. There were no adjustment to the income statement after the tax accountant identified non-qualifying expenses when preparing tax filing. As Tom and his wife were considering turning over more day to day operations to his son and hiring a non-family member as a manager to help his son, he would need the books to provide an accurate picture of the business.

Research methodology
Primary source materials included interviews with the owner, Thomas Gould, his son, Michael Gould, and their Accountant, Tom Mallas. Secondary source materials included monthly and annual financial data from QuickBooks (monthly data are available upon request but are not relevant to the case discussion). Other secondary source materials included geographic, economic, industry, and competitors’ information.

Relevant courses and levels
This case is well suited for an introductory level undergraduate financial accounting course, after accrual accounting and accounting information systems (accounting cycles) have been introduced. When analyzing this case, students will apply concepts and principles of financial statement preparation. The case is also appropriate to serve as a review of accrual accounting, and of income statement and balance sheet preparation at the beginning of an intermediate level financial accounting course. Students can be asked to reformat the income statement from the single-step format to the multiple-step format. By working through financial statements with common errors found in small businesses, students can practice identifying these errors, thus providing a review of the various sections of the income statement and prepare students for more in-depth discussions of each section. In a tax course, this case can stimulate discussions on non-qualifying expenses and common shortcomings in small business accounting.

Authors: Berlich Carolin , Daut Felix , Freund Anna C. , Kampmann Andrea , Killing Benedict , Sommer Friedrich , Wöhrmann Arnt 
Published: January 2017

Synopsis
Deutsche Bahn AG (Deutsche Bahn hereafter) was the former German railroad monopolist until deregulation in 1996. It was a well-known company that operated in worldwide markets for transport and logistics at the time of the case (late 2013). The case “Deutsche Bahn AG: a former monopoly off track?” focuses on the opportunities and challenges faced by Deutsche Bahn with regard to its position in the German individual transportation market. On the one hand, Deutsche Bahn is facing external problems. Increasing competition in short- and long-distance traffic threatens its strong business position. The competition emerged from a growing long-distance bus market and the increase in private railway companies. During the last few years before 2013, Deutsche Bahn has lost several public tenders for individual passenger travel in Germany. On the other hand, Deutsche Bahn has internal problems that endanger its image as a service company. A lack of service quality and the technical condition of its trains has led to rising numbers of customer complaints. In addition, staffing and punctuality problems have exacerbated the situation. One of the main technical issues the company faces is that ordered trains have not been delivered on time. Given the focus on Deutsche Bahn’s domestic challenges, its international business activities are tackled only briefly. While regulatory and political events have an impact on Deutsche Bahn, these are not the main subjects of the case.

Research methodology
This case has been written from public sources. Consequently, no company release is provided. None of the information has been disguised in any way.

Relevant courses and levels
The case is intended for use in a 90-minute strategic management class attended by students at the end of their undergraduate studies or in postgraduate study. Although the case relates to issues in strategic management, the special regulatory environment and some of the issues covered could make the case a useful complement in other classes as well, such as classes in supply chain management (procurement) or the management of public companies. Therefore, students should have basic knowledge in developing strategies, management, marketing, human resource management, and finance.

Theoretical bases
Strategic Analysis and Strategic Management, Railroad Logistics, Deregulation of a former Monopoly, Stakeholder Theory.

Republic Electric: energizing vendor assessment
Authors: Timmerman John E. , Ponomarov Serhiy Y. , Morris Frank 
Published: January 2017

Synopsis
Republic Electric is faced with the need to engage in a systematic process of evaluating vendors for its just-in-time manufacturing. The case gives students the opportunity to think through the process for vendor selection in the context of real-world constraints for a specific organization, to become acquainted with the Delphi technique for developing consensus, to gain hands-on experience with linear averaging, to engage in calculations of value indexes, and to recognize the marketing implications of effectively evaluating vendors. A key takeaway for students is the fact that vendor selection decisions are multifaceted and will vary among organizations depending on each organization’s particular strategic needs, operational constraints, and human judgment.

Research methodology
The case is based upon a consulting assignment with the company that is represented by Republic Electric. The experience was gained first-hand by one of the authors.

Relevant courses and levels
This case is targeted at undergraduate students in marketing, materials management, supply chain management, and purchasing, but can work well in a variety of business courses in which supply chains or the development of evaluation tools is studied, to include graduate classes.

Theoretical bases
The concept of vendor assessment is well developed in the literature and represents a pragmatic, but often neglected, step in the practice of choosing suppliers.

Purpose
The purpose of the paper is to present a framework for moving cross-border ePrescription (eP) and Patient Summary (PS) services forward, bearing in mind the needs and requirements of the European e-health space for cross-border eP and PS services, the limitations of the already developed solutions, as well as outcomes available from other domains.

Design/methodology/approach
The outcomes of previous and current large-scale pilot projects, aiming toward the delivery of electronic cross-border services, are examined. Integration of generic building blocks (BBs) is considered for the further development of cross-border eP and PS, in line with the European Directive on patients’ rights in cross-border health care.

Findings
The e-health domain is expected to greatly benefit from mitigating non-domain concerns such as those for electronic identification, end point detection, non-repudiation and the use of electronic signatures and trust establishments for basic cross-border public services in Europe.

Research limitations/implications
Research limitations are related to the fact that electronic identification, electronic signature and semantic issues have not been fully addressed yet at a European level to support cross-border services.

Practical implications
Practical implications are related to the cooperation, European level compatibility and sustainability of the underlying national infrastructures required to support reliable and secure exchange of medical data, as well as the readiness to address continuously evolving interoperability, legal and security requirements in a cross-border setting.

Originality/value
The need for consolidating the existing outcomes of non-health specific BBs is examined for two high-priority e-health services. Ongoing progress is presented, together with related issues that need to be resolved for improving technical certainty and making it easier to use health-care services abroad in cases of emergency.
Macro‐ and microvascular endothelial dysfunction in diabetes
Authors: Shi Yi , Vanhoutte Paul M. 
Published: January 2017

AbstractEndothelial cells, as well as their major products nitric oxide (NO) and prostacyclin, play a key role in the regulation of vascular homeostasis. Diabetes mellitus is an important risk factor for cardiovascular disease. Diabetes‐induced endothelial dysfunction is a critical and initiating factor in the genesis of diabetic vascular complications. The present review focuses on both large blood vessels and the microvasculature. The endothelial dysfunction in diabetic macrovascular complications is characterized by reduced NO bioavailability, poorly compensated for by increased production of prostacyclin and/or endothelium‐dependent hyperpolarizations, and increased production or action of endothelium‐derived vasoconstrictors. The endothelial dysfunction of microvascular complications is primarily characterized by decreased release of NO, enhanced oxidative stress, increased production of inflammatory factors, abnormal angiogenesis, and impaired endothelial repair. In addition, non‐coding RNAs (microRNAs) have emerged as participating in numerous cellular processes. Thus, this reviews pays special attention to microRNAs and their modulatory role in diabetes‐induced vascular dysfunction. Some therapeutic strategies for preventing and restoring diabetic endothelial dysfunction are also highlighted.

Published: January 2017

BackgroundThe Romhilt‐Estes point score system (RE) is an established ECG criterion for diagnosing left ventricular hypertrophy (LVH). In this study, we assessed for the first time, whether RE and its components are predictive of sudden cardiac arrest (SCA) independent of left ventricular (LV) mass.MethodsSudden cardiac arrest (SCA) cases occurring between 2002 and 2014 in a Northwestern US metro region (catchment area approx. 1 million) were compared to geographic controls. ECGs and echocardiograms performed prior to the SCA and those of controls were acquired from the medical records and evaluated for the ECG criteria established in the RE score and for LV mass.ResultsTwo hundred forty‐seven SCA cases (age 68.3 ± 14.6, male 64.4%) and 330 controls (age 67.4 ± 11.5, male 63.6) were included in the analysis. RE scores were greater in cases than controls (2.5 ± 2.1 vs. 1.9 ± 1.7, p < .001), and SCA cases were more likely to meet definite LVH criteria (18.6% vs. 7.9%, p < .001). In a multivariable model including echocardiographic LVH and LV function, definite LVH remained independently predictive of SCA (OR 2.04, 95% CI 1.16–3.59, p = .013). The model was replicated with the individual ECG criteria, and only SV1.2 ≥ 30 mm and delayed intrinsicoid deflection remained significant predictors of SCA.ConclusionLeft ventricular hypertrophy (LVH) as defined by the RE point score system is associated with SCA independent of echocardiographic LVH and reduced LV ejection fraction. These findings support an independent role for purely electrical LVH, in the genesis of lethal ventricular arrhythmias.
