Operations strategies of engine assembly plants in the Brazilian automotive industry
Authors: Alves Filho Alceu Gomes , Nogueira Edemilson , Bento Paulo Eduardo Gomes 
Published: April 2015

Purpose– The purpose of this paper is to identify and analyze the operations strategies (OSs) adopted by six of the all seven automobile engine manufacturers in action in Brazil during the years of 2005 and 2006.Design/methodology/approach– Semi-structured interviews were held with at least one of the top managers at each engine manufacturing plant to collect information about the aforementioned strategies. The questions were aimed at identifying possible changes, over a four years period, in some of the operations-related competitive priorities and decision areas.Findings– This research revealed the strategies adopted by six of the all seven major automobile engine manufacturers installed in Brazil in 2005, enabling a discussion of relevant themes from both the theoretical and practical standpoints. Competitive priorities and decision areas form a very inter-related system and any significant change of OSs requires significant investments, effort and time.Research limitations/implications– Case studies were carried out in a specific context of the automobile market in Brazil in 2005 and 2006. Firms must treat operations as a system that changes continuously.Practical implications– In dealing with operations as a system, managers should know and apply OS concepts. This is even more important at dynamic (economic) sectors/industries.Originality/value– This paper describes and discusses – via qualitative research and in a comprehensive way – the OSs of two groups (established and entrant manufacturers) of firms in a relatively dynamic context in Brazil.
Moral compass framework
Authors: Green Pam , Bowden John A. 
Published: April 2015

Purpose– The purpose of this paper is as follows: locate our moral compass framework (Bowden and Green, 2014) within the moral development literature; demonstrate how the framework can be used to analyse complex system-wide problems; and propose change in doctoral education.Design/methodology/approach– This paper shows the analysis of transcripts of 50 interviews with doctoral students and supervisors. Four scenarios, each a composite derived primarily from the interview data, were analysed using the framework, complemented by reference to the moral development literature.Findings– The structure of the framework and meaning of the constructs’ collective morality, moral advocacy and moral mediation are elaborated and further explained through the analysis of the four scenarios, showing how the framework can contribute to resolution of complex system-wide problems and how they facilitate moral development within a multi-level system. Six proposals for change in the doctoral education system, at the individual, organisational and national levels, are derived from those analyses.Originality/value– The use of our moral compass framework to analyse the four scenarios demonstrates its applicability to real situations and its complementarity with the moral development literature. The paper also shows that the framework is more powerful and of broader impact than the moral development models published to date. The changes proposed for the doctoral education system, based on the moral compass framework and its application to the four scenarios, have the potential to change practice in ways that benefit everyone involved in the system – candidates, supervisors, management and government personnel.
Students’ environmental responsibility and their willingness to pay for green buildings
Authors: Attaran Sharmin , Celik Bilge Gokhan 
Published: April 2015

Purpose– The purpose of this study is to explore environmental attitudes and how such attitudes, when combined with a specific cost, can affect environmental behavior. Environmental attitudes are important to study due to the rising belief by building occupants that they are owed safe, healthy, environmentally responsible, and comfortable living environments. Universities around the world are responding to such demands as the majority of prospective college students and their parents claim that the environmental record is a determining factor in their selection of a university. Therefore, this study examines the environmental responsibility levels of a sample student population and to explore how these scores, along with gender, impact their willingness to pay for studying and living in green buildings.Design/methodology/approach– An online survey consisting of three parts was administered to undergraduate university students to measure environmental responsibility, willingness to pay and demographic variables. Statistical analyses including ANOVA,t-tests and correlation were conducted to explore relationships among variables.Findings– Results of statistical analyses show a direct correlation between environmental responsibility and willingness to pay for green buildings, as defined by a leading green building assessment system. Results also show that female students are more environmentally responsible than males.Practical implications– Successful generalizations of the findings of this research may lead to better marketing of green buildings to the general public.Originality/value– Findings present a unique opportunity for university administrations to develop more focused messages when communicating their environmental record with current and potential students.

Calculation of account reachability risk for users having multiple SNS accounts from user’s profile and regional information
Authors: Yoshikuni Ayano , Watanabe Chiemi 
Published: April 2015

Purpose
– The purpose of this paper was to argue that social networking service users should be vigilant in protecting the relationship between multiple accounts.

Design/methodology/approach
– In this paper, the authors propose the use of account reachability, a measure of privacy risk which demonstrates the possibility of a stranger finding a user’s private account based on information in their public account. In addition, they present ARChecker, a tool to calculate the value of account reachability. ARChecker also provides advice on how to modify the user’s profiles and messages to decrease the privacy risk.

Findings
– The system very simply checks account reachability and shows the result and reasons for accessibility to personal information. From the results, users can learn how to protect themselves from privacy risk by taking certain measures.

Originality/value
– This paper proposes account reachability, a new measure of privacy risk, and presents ARChecker, a tool to calculate the value of account reachability.
Effective keyword query structuring using NER for XML retrieval
Authors: Roko Abubakar , Doraisamy Shyamala , Jantan Azrul Hazri , Azman Azreen 
Published: April 2015

Purpose
– The purpose of this paper is to propose and evaluate XKQSS, a query structuring method that relegates the task of generating structured queries from a user to a search engine while retaining the simple keyword search query interface. A more effective way for searching XML database is to use structured queries. However, using query languages to express queries prove to be difficult for most users since this requires learning a query language and knowledge of the underlying data schema. On the other hand, the success of Web search engines has made many users to be familiar with keyword search and, therefore, they prefer to use a keyword search query interface to search XML data.

Design/methodology/approach
– Existing query structuring approaches require users to provide structural hints in their input keyword queries even though their interface is keyword base. Other problems with existing systems include their inability to put keyword query ambiguities into consideration during query structuring and how to select the best generated structure query that best represents a given keyword query. To address these problems, this study allows users to submit a schema independent keyword query, use named entity recognition (NER) to categorize query keywords to resolve query ambiguities and compute semantic information for a node from its data content. Algorithms were proposed that find user search intentions and convert the intentions into a set of ranked structured queries.

Findings
– Experiments with Sigmod and IMDB datasets were conducted to evaluate the effectiveness of the method. The experimental result shows that the XKQSS is about 20 per cent more effective than XReal in terms of return nodes identification, a state-of-art systems for XML retrieval.

Originality/value
– Existing systems do not take keyword query ambiguities into account. XKSS consists of two guidelines based on NER that help to resolve these ambiguities before converting the submitted query. It also include a ranking function computes a score for each generated query by using both semantic information and data statistic, as opposed to data statistic only approach used by the existing approaches.
Relevance status value model of Index Islamicus on Islamic History and Civilizations
Authors: Othman Roslina , Salahuddin Ashraf Ali 
Published: April 2015

Purpose
– The purposes of this study were to measure the relevance status of Index Islamicus, evaluate the semantic correlation between a query and documents and inquire the basis of its rank. Sorting the retrieved results from the most relevant to the least relevant is the common option of an information retrieval system. This sorting mechanism or relevance judgment is computed by measuring closeness of query with its documents.

Design/methodology/approach
– Forming up 100 queries on Islamic History and Civilizations, with two indexing elements (keyword and concept), a laboratory experiment was generated on its first ten items of the rank. Throughout an experimental research design, the relevance status value formula was used to measure system-computed rank and compare it with mean average precision.

Findings
– The results showed that the average status value of Index Islamicus’s ranking on relevance criterion was 18 per cent effective in terms of retrieving precise documents. Despite the main focus of this study being only on one subject domain and the items calculated were only 1,000, this small percentage of its ranking mechanism proved that semantic correlations between queries with subject domain did not achieve the satisfactory level.

Research limitations/implications
– Implication of this study could be a guideline for further research on ranking mechanism of other search engines because the limitation of this study was Index Islamicus being the only database, which was the focus of this study.

Practical implications
– Throughout this study, Index Islamicus would be benefited knowing the status of its ranking mechanism as well as other databases can make further research on their own ranking method following this study.

Social implications
– Researchers and vendors of online databases can ensure their users a true platform of search engine with a proper ranking list.

Originality/value
– Relevance status value model for Index Islamicus on Islamic History and Civilization that allows the system to rank documents according to the match between document and query and gives the idea of a better index. The model improves the system’s ranking mechanism, and promotes the use of semantic relationships. This research promotes the computation of relevance status value by domain for capturing subject-specific relevance criteria and semantic relationships.
Influence of individual investor sentiment on Taiwan option prices during 2007-2010 financial crisis
Authors: Szu Wen-Ming , Yang Wan-Ru 
Published: April 2015

Purpose
– This paper investigates changes in risk-neutral distribution derived from Taiwan stockindex options under different market conditions. The purpose of this paper is to explore whether individual investor sentiment significantly influences the Taiwan option prices.

Design/methodology/approach
– The authors adopt the optimization method to estimate the risk-neutral distribution from the Taiwan stock index options and use the t-test to examine the difference in risk-neutral skewness, kurtosis, and confidence interval between the pre-crisis and crisis periods. This paper tests the impact of individual investor sentiment on risk-neutral skewness and confidence interval in two sub-periods.

Findings
– The authors find that errors in individual investors’ expectations significantly influence the Taiwan stock index option prices.

Research limitations/implications
– The data concerning the sentiment of speculative institutional investors are incomplete for the Taiwan option market. Therefore, this paper focusses on the analysis of individual investor sentiment. Further research can study the impact of institutional investor sentiment in emerging markets.

Social implications
– The previous literature has suggested that option prices reflect information before the information is revealed in stock prices. Therefore, an important implication is to analyze the information quality revealed in option prices by studying whether the changes in option prices are due to investor sentiment or non-sentiment-related components.

Originality/value
– Most of the studies in the literature have focussed on the US option market, and their applicability may vary across different microstructures. This paper shows that the influence of individual investor sentiment in an emerging market is different from that in the US market.
Portfolio constituency rules and the value premium in the small-cap space
Authors: Scislaw Kenneth E. , McMillan David G 
Published: April 2015

Purpose
– Market-based value style equity portfolios do not systematically outperform market-based growth style equity portfolios, despite considerable academic research that suggests that they should. This is an unresolved puzzle in the long lineage of work on this topic. The purpose of this paper is to question whether portfolio constituency rules employed by active growth and value equity investment managers might explain this puzzle.

Design/methodology/approach
– The authors use the traditional research design and methodology of Fama and French (1993) to ensure comparability of results to prior research. Further, the authors adapt the return decomposition method of Keim (1999) to specifically answer the question in the research.

Findings
– The authors find that restrictive constituency rules that omit the smallest, most illiquid stocks improve the performance of both value and growth stock portfolios. However, the authors find the impact of constituency rule restrictions on portfolio returns to be asymmetric with respect to value and growth in the small-cap investment space. Growth portfolios benefit from these changes more than value portfolios. Consistent with prior research, the authors find that value and growth style portfolios constructed from more liquid equities to be void of a statistically significant value-minus-growth return premium. The authors suggest these results might go a long way in explaining why market-based growth fund returns generally equal those of their value fund counterparts over time.

Originality/value
– The research question central to the research, the value equity premium, has been investigated by researchers around the world over the last 20 years. The 20 year lineage of global published research on the value equity premium does, however, contain several unresolved questions. The paper specifically asks why the premium, long observed in global equity market returns, does not appear in market-based passive or active equity portfolios. This puzzle exists at the heart of the origins of the return premium itself and has serious implications for investment practitioners. If the matter cannot be reconciled, then market participants might rightly view the entire 20 year lineage of published research as irrelevant. The paper is one of few that has now extended the long lineage of research to its application in real markets.
A comparative analysis of printing techniques by using an active concentric ring electrode for bioelectrical recording
Authors: Garcia-Breijo Eduardo , Prats-Boluda Gema , Lidon-Roger Jose Vicente , Ye-Lin Yiyao , Garcia-Casado Javier 
Published: April 2015

Purpose
– This paper aims to present a comparison between three types of manufacturing techniques, namely, screen-printed, inkjet and gravure, using different types of inks, for the implementation of concentric ring electrodes which permit estimation of Laplacian potential on the body surface.

Design/methodology/approach
– Flexible concentric ring electrodes not only present lower skin–electrode contact impedance and lower baseline wander than rigid electrodes but are also less sensitive to interference and motion artefacts. The above three techniques allow printing of conductive inks on flexible substrates, and with this work, the authors aim to study which is the best technique and ink to obtain the best electrode response.

Findings
– From the results obtained regarding ink thickness, resistivity, electrode resistance and other performance parameters derived from electrocardiographic signal recording tests, it can be said that concentric electrodes using the screen-printing and inkjet techniques are suitable for non-invasive bioelectric signal acquisition.

Originality/value
– The development of new types of inks and substrates for the electronics industry and the adaptation of new manufacturing techniques allow for an improvement in the development of electrodes and sensors.

Published: April 2015

Purpose
– This study aims to provide a flexible and cost-effective solution of 3D heterogeneous integration for applications such as micro-electro-mechanical system (MEMS) applications and smart sensor systems.

Design/methodology/approach
– A novel 3D system-in-package (SiP) based on stacked silicon submount technology was successfully developed and well-demonstrated by the fabrication and assembly process of a selected smart lighting module.

Findings
– The stacked module consists of multiple layers of silicon submounts which can be designed and fabricated in parallel. The bonding and interconnecting process is quite simple and does not require complicated equipment. The 3D stacking design offers higher silicon efficiency and miniaturized package form factor. The submount wafer can be assembled and tested at the wafer level, thus reducing the cost and improving the yield.

Research limitations/implications
– The embedding design presented in this paper is applicable for modules with limited number of passives. When it comes to cases with more passive devices, new process needs to be developed to achieve fast, inexpensive and reliable assembly.

Originality/value
– The presented 3D SiP design is novel for applications such as smart lighting, Internet of Things, MEMS systems, etc.
