Analysis of virtualized cloud server together with shared storage and estimation of consolidation ratio and TCO/ROI
Authors: Rong Chang Bao , Tsai Hsiu-Fen , Chen Chi-Ming , Huang Chien-Feng 
Published: November 2014

Purpose
– The physical server transition to virtualized infrastructure server have encountered crucial problems such as server consolidation, virtual machine (VM) performance, workload density, total cost of ownership (TCO), and return on investments (ROIs). In order to solve the problems mentioned above, the purpose of this paper is to perform the analysis of virtualized cloud server together with shared storage as well as the estimation of consolidation ratio and TCO/ROI in server virtualization.

Design/methodology/approach
– This paper introduces five distinct virtualized cloud computing servers (VCCSs), and provides the appropriate assessment to five well-known hypervisors built in VCCSs. The methodology the authors proposed in this paper will gives people an insight into the problem of physical server transition to virtualized infrastructure server.

Findings
– As a matter of fact, VM performance seems almost to achieve the same level, but the estimation of VM density and TCO/ROI are totally different among hypervisors. As a result, the authors have the recommendation to choose the hypervisor ESX server if you need a scheme with higher ROI and lower TCO. Alternatively, Proxmox VE would be the second choice if you like to save the initial investment at first and own a pretty well management interface at console.

Research limitations/implications
– In the performance analysis, instead of ESX 5.0, the authors adopted ESXi 5.0 that is free software, its function is limited, and does not have the full functionality of ESX server, such as: distributed resource scheduling, high availability, consolidated backup, fault tolerance, and disaster recovery. Moreover, this paper do not discuss the security problem on VCCS which is related to access control and cryptograph in VMs to be explored in the further work.

Practical implications
– In the process of virtualizing the network, ESX/ESXi has restrictions on the brand of the physical network card, only certain network cards can be detected by the VM. For instance: Intel and Broadcom network cards. The newer versions of ESXi 5.0.0 and above now support parts of Realtek series (Realtek 8186, Realtek 8169, and Realtek 8111E).

Originality/value
– How to precisely assess the hypervisor for server/desktop virtualization is also of hard question needed to deal with it crisply before deploying new IT with VCCS on site. The authors have utilized the VMware calculator and developed an approach to server/desktop consolidation, virtualization performance, VM density, TCO, and ROIs. As a result, in this paper the authors conducted a comprehensive approach to analyze five well-known hypervisors and will give the recommendation for IT manager to choose a right solution for server virtualization.
The visual tracking system using a stereo vision robot
Authors: Yeh Long-Jyi , Han Lee Tsung , Hsu Kuei-Shu 
Published: November 2014

Purpose
– The purpose of this paper is to use vision stereo to simultaneously acquire image pairs under a normal environment. Then the methods of moving edges detection and moving target shifting are applied to reduce noise error in order to position a target efficiently. The target is then double confirmed via image merge and alignment. After positioning, the visual difference between the target and the image created by the stereo vision system is measured for alignment. Finally, the image depth of the target is calculated followed by real-time target tracking.

Design/methodology/approach
– This study mainly applies Sobel image principle. In addition, moving edges detection and moving target shifting are also used to work with system multi-threading for improving image identification efficiency.

Findings
– The results of the experiment suggest that real-time image tracking and positioning under a pre-set environment can be effectively improved. On the other hand, tracking and positioning are slightly affected under a normal environment. Errors of distance measurements occur because there is more noise existing.

Research limitations/implications
– This study mainly determines the movements and positioning of an object or a target via image. However, the stability of moving edges detection executed by the stereo vision system can be affected if the light sources in an environment are too strong or extreme.

Practical implications
– So far the method of tracking and positioning a moving object has been applied to surveillance systems or the application which requires measuring and positioning under a normal environment. The method proposed by this study can also be used to construct a 3D environment.

Originality/value
– The method proposed by this study can also be used to construct a 3D environment or tracking moving object to measure the distance.
Assessing the change process of Lean Six Sigma: a case analysis
Authors: Lertwattanapongchai Suriya , William Swierczek Fredric 
Published: November 2014

Purpose
– This paper aims to present an integrative conceptual framework of Lean Six Sigma (LSS) as a project and an organizational change process. To assess the process, the LSS success factors are identified. Their impact on both project outcomes and people is determined.

Design/methodology/approach
– An in-depth review of success factors resulted in a set of indicators related both to the LSS factors and to the change process. A comparative case analysis of three multinational companies (MNCs) implementing LSS in Thailand is presented. The indicators were used to identify patterns in the cases related to effective implementation through content analysis.

Findings
– The case analysis showed that an effective combination of a strong LSS project design and a comprehensive change management process achieved positive impacts in business results, employee learning and job satisfaction.

Practical implications
– To be successful LSS cannot only focus on a good project design. Champions and key practitioners must also apply best practices in change management.

Originality/value
– There are few examples of the integration of LSS project design and the change management process in Asia. Additionally, the case analysis focuses on examples of MNC operations in Thailand. The research supported the importance of integrating change management and project management for success.
The interplay of the unemployment compensation system, fixed-term contracts and rehirings
Authors: María Arranz José , García-Serrano Carlos 
Published: November 2014

Purpose
– Using a Spanish administrative data set, the authors document the importance of recalls in labour market transitions. The authors focus on two issues: the interplay between the unemployment compensation system, the widespread use of fixed-term contracts and the layoff-rehire process; and the use of implicit contracts and, hence, the existence of cross-subsidisation between industries and firms within unemployment insurance. The purpose of this paper is to estimate a duration model with competing risks of exits in order to investigate the individual, job and firm attributes that influence the probabilities of leaving unemployment to return to the same employer or to find a new job. The findings indicate that recalls are very common and that, although they are widespread among the labour market, there are certain types of contract, firms and sectors which are more prone to use them.

Design/methodology/approach
– The authors estimate a duration model with competing risks of exits in order to investigate the individual, job and firm attributes that influence the probabilities of leaving unemployment to return to the same employer or to find a new job with a different employer.

Findings
– The findings indicate that recalls are very common and that, although they are widespread along the Spanish labour market, there are certain types of contract, firms and sectors which are more prone to use them.

Practical implications
– Overall, the results suggest that there is room for the reform of the way the UCS is financed, in combination with changes in other labour market institutions.

Originality/value
– The contribution of this paper is twofold. First, it documents the importance of rehirings in labour market transitions, in general, and in compensated unemployment, in particular, highlighting the use of different types of contract (in particular, temporary ones) and using a large data set for Spain. Second, it examines the interplay between the unemployment compensation system, the use of temporary contracts and the layoff-rehire process, focusing its attention on the likely cross-subsidisation of firms and sectors with respect to unemployment benefits . This constitutes a relevant research and policy issue since it has to do with the design of the unemployment compensation system.
Understanding the indigenous Chinese concept of suzhi (素质) from an HRM perspective
Authors: G. Wang Greg , Lamond David , Worm Verner , Gao Wenshu , Yang Shengbin 
Published: November 2014

Purpose– The purpose of this paper is to examine the indigenous Chinese concept ofsuzhi(素质) with the aim of furthering the development of Chinese human resource management (HRM) research and practice.Design/methodology/approach– An extensive review of the literature onsuzhi, published in the West, as well as in China, is the basis for proffering an organizational-level conceptualization ofsuzhiin the Chinese context.Findings– Instead of understanding it as a free-floating signifier, we argue thatsuzhican be considered as a criterion-based framework for HRM research and practice.Suzhiresearch is classified into two major sources – indigenous Chinese and indigenized Western constructs. We further make a distinction between intrinsic and extrinsicsuzhi, and analyze a popular set ofsuzhicriteria, considering de (morality) and cai (talent), while focusing on de in HRM selection (德才兼备, 以德为先). As multilevel and multidimensional framework,suzhicriteria may form different gestalts in different organizations and industries.Research limitations/implications– From a social cultural and historical perspective, HRM research that incorporates a combination of indigenous and indigenizedsuzhicharacteristics may receive better acceptance by individuals, organizations and the society in the Chinese context. Accordingly, the reconstruction ofsuzhiinto manageable and measurable dimensions can be undertaken for more effective HRM practice in the Chinese context.Originality/value– The HRM literature is advanced by linking the indigenoussuzhidiscourse to Chinese indigenous HRM research and practice.
Director of SEC’s Division of Investment Management discusses alternative mutual funds
Authors: F. Kerr Richard 
Published: November 2014

Purpose
– To alert participants in the mutual fund industry to regulatory developments in the alternative mutual fund space as articulated by the SEC’s Director of the Division of Investment Management.

Design/methodology/approach
– Reviews the Director’s discussion of the SEC’s concerns related to Valuation, Liquidity, Leverage and Disclosure resulting from the proliferation of alternative mutual funds. Additionally, summarizes the Director’s comments regarding Board oversight of alternative mutual funds.

Findings
– While the Director’s speech does not establish any new law or regulation, it is a practical summary of the SEC’s expectations for mutual fund complexes when implementing and operating mutual funds with alternative investment strategies that have historically been the province of private funds.

Originality/value
– Practical explanation from experienced financial institutions lawyers.
Benefits of management disclosure precision on analysts’ forecasts
Authors: Chi Yu-Ho , A. Ziebart David 
Published: November 2014

Purpose
– The purpose of this paper is to examine the impact of management’s choice of forecast precision on the subsequent dispersion and accuracy of analysts’ earnings forecasts.

Design/methodology/approach
– Using a sample of 3,584 yearly management earnings per share (EPS) forecasts and 10,287 quarterly management EPS forecasts made during the period of 2002-2007 and collected from the First Call database, the authors controlled for factors previously found to impact analysts’ forecast accuracy and dispersion and investigate the link between management forecast precision and attributes of the analysts’ forecasts.

Findings
– Results provide empirical evidence that managements’ disclosure precision has a statistically significant impact on both the dispersion and the accuracy of subsequent analysts’ forecasts. It was found that the dispersion in analysts’ forecasts is negatively related to the management forecast precision. In other words, a precise management forecast is associated with a smaller dispersion in the subsequent analysts’ forecasts. Evidence consistent with accuracy in subsequent analysts’ forecasts being positively associated with the precision in the management forecast was also found. When the present analysis focuses on range forecasts provided by management, it was found that lower precision (a larger range) is associated with a larger dispersion among analysts and larger forecast errors.

Practical implications
– Evidence suggests a consistency in inferences across both annual and quarterly earnings forecasts by management. Accordingly, recent calls to eliminate earnings guidance through short-term quarterly management forecasts may have failed to consider the linkage between the attributes (precision) of those forecasts and the dispersion and accuracy in subsequent analysts’ forecasts.

Originality/value
– This study contributes to the literature on both management earnings forecasts and analysts’ earnings forecasts. The results assist in policy deliberations related to calls to eliminate short-term management earnings guidance.
Auditor industry specialization and audit fees surrounding Section 404 implementation
Authors: Fleming Damon , Hee Kevin , N. Romanus Robin 
Published: November 2014

Purpose
– The purpose of this paper is to investigate the association between auditor industry specialization and audit fees surrounding Section 404 implementation.

Design/methodology/approach
– With a sample of 1,006 industrial firms over the 2003-2005 reporting periods, an ordinary least square regression model was used to regress change in audit fees on auditor specialization measure and other control variables.

Findings
– It was found that auditor industry specialization is negatively related to the change in audit fees during the first year of Sarbanes–Oxley Act (SOX) compliance (2003-2004). It was also found that there were no significant cost savings associated with auditor industry specialization in the second year of SOX compliance (2004-2005).

Practical implications
– These results suggest that industry-specific expertise may enable auditors to adapt more efficiently to new significant audit standards and regulations, but that such efficiencies are likely to be most pronounced during the initial implementation year.

Originality/value
– Auditor competition and auditor specialization are at the forefront of today’s ever-changing accounting industry. Analysis of a contemporary auditing issue (auditor specialization) in the context of major legislation (SOX) provides a research setting that gives both academics and practitioners valuable insight toward how future legislation can impact current accounting industry issues such as the increasing need to have more expertise.
The explicit dimension: what we could not learn from Polanyi
Authors: Grandinetti Roberto 
Published: November 2014

Purpose– This paper aims to clarify that the link between Michael Polanyi’s tacit knowledge theory and the field of knowledge management research does not withstand in-depth analysis. Second, the paper suggests a way to emerge from the ambiguity that unavoidably results from using the tacit knowledge concept in knowledge management studies.Design/methodology/approach– The paper begins with an analysis of the tacit knowledge theories developed by Polanyi, by cognitive psychologists and by knowledge management scholars. It goes on to formulate a new conceptual framework of tacit knowledge.Findings– This proposal consists in assuming that the terms “unconscious” and “tacit” are not interchangeable and, consequently, redefining the epistemological profile of knowledge management theory so as to acknowledge the existence of two planes of analysis. One is occupied by the process through which individuals gain knowledge, or the knowing process, which may be unconscious or conscious. The other contains the dichotomy between tacit knowledge and explicit knowledge, where the two terms indicate two alternative states that only consciously developed knowledge can adopt.Research limitations/implications– The paper provides support for the two-planes idea by referring to contributions from various disciplines, and particularly from cognitive psychology studies concerned with unconscious knowledge; a more thorough and extensive review would be needed, however, to fully demonstrate the proposal.Originality/value– Distinguishing between two planes of analysis makes it possible to unveil the mystery of tacit knowledge.

Published: November 2014

AbstractObjectivesThe objective was to determine the association between the abdominal seat belt sign and intra‐abdominal injuries (IAIs) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions (MVCs).MethodsThis was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVCs. Patient history and physical examination findings were documented before abdominal computed tomography (CT) or laparotomy. Seat belt sign was defined as a continuous area of erythema, ecchymosis, or abrasion across the abdomen secondary to a seat belt restraint. The relative risk (RR) of IAI with 95% confidence intervals (CIs) was calculated for children with seat belt signs compared to those without. The risk of IAI in those patients with seat belt sign who were without abdominal pain or tenderness, and with Glasgow Coma Scale (GCS) scores of 14 or 15, was also calculated.ResultsA total of 3,740 children with seat belt sign documentation after blunt torso trauma in MVCs were enrolled; 585 (16%) had seat belt signs. Among the 1,864 children undergoing definitive abdominal testing (CT, laparotomy/laparoscopy, or autopsy), IAIs were more common in patients with seat belt signs than those without (19% vs. 12%; RR = 1.6, 95% CI = 1.3 to 2.1). This difference was primarily due to a greater risk of gastrointestinal injuries (hollow viscous or associated mesentery) in those with seat belt signs (11% vs. 1%; RR = 9.4, 95% CI = 5.4 to 16.4). IAI was diagnosed in 11 of 194 patients (5.7%; 95% CI = 2.9% to 9.9%) with seat belt signs who did not have initial complaints of abdominal pain or tenderness and had GCS scores of 14 or 15.ConclusionsPatients with seat belt signs after MVCs are at greater risk of IAI than those without seat belt signs, predominately due to gastrointestinal injuries. Although IAIs are less common in alert patients with seat belt signs who do not have initial complaints of abdominal pain or tenderness, the risk of IAI is sufficient that additional evaluation such as observation, laboratory studies, and potentially abdominal CT scanning is generally necessary.
A Simple Method for the Investigation of Cell Separation Effects of Blood With Physiological Hematocrit Values
Authors: Gester Kathrin , Jansen Sebastian V. , Stahl Marion , Steinseifer Ulrich 
Published: November 2014

AbstractEven though the separation of blood into erythrocyte‐rich and erythrocyte‐poor areas is well known in physiological setups such as small vessels, it has recently come into focus in small gaps in cardiovascular applications. Studies show that separation effects occur, for example, in gaps in hydrodynamic bearings, where they can have a positive effect on hemolysis. Separation effects depend on the hematocrit value, but due to visualization issues, studies in small gaps used very low hematocrit values. In this study, a test setup and an evaluation method for the investigation of separation effects of blood with hematocrit values of 30, 45, and 60% were developed. The erythrocyte distribution was evaluated by means of gray scale value distribution. This principle is based on the fact that an erythrocyte‐rich region is more opaque than an erythrocyte‐poor region. The experimental setup is designed in a way that no further processes (e.g., fluorescence labeling) need to be carried out which might change the properties of the membrane of the erythrocytes, and therefore their flow properties. Additionally, the method is executable with basic laboratory equipment, which makes it applicable for many laboratories. To validate the feasibility of the method, the influence of the diameter and the flow rate on the migration of erythrocytes were studied in micro channels for three different physiological hematocrit values. Even though no individual cells were traced, plasma layer and areas of high erythrocyte concentration could be identified. Dependencies of the erythrocyte distribution on flow rate and channel diameter were validated. The influence of the hematocrit value was demonstrated as well and showed the hematocrit value to be a crucial factor when investigating cell separation. The experimental results were consistent with findings in the literature. As the developed method is suitable for physiological hematocrit values and easy to handle, it provides an optimal basis for cell separation studies in gap models with whole blood, for example, hydrodynamic bearings, where it can be used to optimize these devices.
The Origin of Representational Drawing: A Comparison of Human Children and Chimpanzees
Authors: Saito Aya , Hayashi Misato , Takeshita Hideko , Matsuzawa Tetsuro 
Published: November 2014

To examine the evolutional origin of representational drawing, two experiments directly compared the drawing behavior of human children and chimpanzees. The first experiment observed free drawing after model presentation, using imitation task. From longitudinal observation of humans (N = 32, 11–31 months), the developmental process of drawing until the emergence of shape imitation was clarified. Adult chimpanzees showed the ability to trace a model, which was difficult for humans who had just started imitation. The second experiment, free drawing on incomplete facial stimuli, revealed the remarkable difference between two species. Humans (N = 57, 6–38 months) tend to complete the missing parts even with immature motor control, whereas chimpanzees never completed the missing parts and instead marked the existing parts or traced the outlines. Cognitive characteristics may affect the emergence of representational drawings.
