Student seminar program for improving academic presentation skills for PhD students in science
Authors: Ohnishi Satomi , Ford Judith Helen 
Published: April 2015

Purpose
– The study aims to reveal how the students improved their academic presentation skills and the limitations to improvement with or without influences of students’ language backgrounds. Since the career paths of postgraduates have become more diverse in recent years, generic skills training is increasingly included in postgraduate programmes in addition to specific research training. However, PhD education generally adopts a traditional style, often relying on an individual supervisor without the inclusion of specific programmes to improve students’ generic skills. As academic presentation skills are crucial to research and are a generic skill that PhD students in science must acquire, we propose that existing student seminar programmes can be used effectively as an active training programme to improve these skills.

Design/methodology/approach
– To design effective student seminars, we investigated how PhD students improved their academic presentation skills when opportunities to give regular seminars were provided and students were given detailed scores that measured performance in specific areas of presentation competency. We outline an extensive case study of 95 PhD students who presented at student seminars over a period of six years (2006-2011). Valid data of 73 students were collected, and data of 58 students were used for detailed analysis. Performance in three major factors important to presentation skills: structure, visuals and delivery, were scored for each seminar, and the scores underwent detailed statistical analysis.

Findings
– Our key findings are that international students obtained better scores than Australian students for their first presentations while Australian students obtained a better score than international in for their second and the later presentations. The improvement of international students is slower than Australian students but occurs at a steadier pace. International students showed difficulty in improving answering questions.

Originality/value
– This is the first time that a longitudinal study on PhD students’ development of academic presentation skills has been undertaken. Our results revealed how the students improved academic presentation skills and that the limitations to improvement depended on their language backgrounds. We discuss our findings from the viewpoint of student language backgrounds and the process of adaptation to academic culture.
The generic-discipline dilemma: learning advising in quantitative literacy
Authors: Blumenstein Marion 
Published: April 2015

Purpose
– This paper aims to provide insights into the experiences of and challenges confronting higher degree research students and learning advisors (LAs) regarding data analysis support. The ability to handle data and use numerical evidence systematically is an important transferable skill and essential for the successful completion of a quantitative research thesis.

Design/methodology/approach
– A combination of qualitative and quantitative data was used, enabling a convergence of findings: the questionnaire and one-on-one advisory sessions feedback gathered information on the student experience, while semi-structured interviews provided data on the LAs’ perspective.

Findings
– Phenomenographic analysis of interviews revealed many challenges associated with centralised learning support provision. Learning advisors recognised not only different disciplinary needs but also the tensions associated with working centrally and cross-disciplinary. Students identified a need for more practice-orientated training opportunities in data analysis during their postgraduate and doctoral research.

Practical implications
– Understanding gained from students’ and LAs’ experiences are essential for changes of university-wide teaching and learning strategies. The collection of “bottom-up” data on the student experience combined with data on learning thresholds provided by faculty and student learning support units would allow a coordinated, institution-wide approach to identified learning needs.

Originality/value
– Developing a community of practice concerned with quantitative literacy means that staff with expert knowledge, regardless of discipline affiliation, can provide an environment in which students are able to develop their analytical skills further and can participate in ongoing discussions on real-life research and data analysis issues.

Authors: Latz Amanda O. , Bolin Jocelyn H. , Quick Marilynn (Marks) , Jones Ruth , Chapman Austin 
Published: April 2015

Purpose
– The purpose of this paper is to provide information regarding the ways in which the authors’ College’s faculty use paper within their pedagogical practice. A related purpose was to ascertain faculty interest in professional development initiatives related to reducing paper usage through technological affordances.

Design/methodology/approach
– A survey was developed and administered to the faculty within the university’s Teachers College. The survey was built to assess faculty pedagogical use of paper. Both quantitative and qualitative data were collected via the survey.

Findings
– The results suggested that digital resources are widely used by faculty, and students are encouraged to conserve paper. However, many faculty are uncomfortable with the complete elimination of paper.

Originality/value
– Modeling and promoting environmentally sustainable pedagogical practice is imperative within institutions charged with preparing the next generation of educators.
Living green: examining sustainable dorms and identities
Authors: Watson Lesley , Johnson Cathryn , Hegtvedt Karen A , Parris Christie L. 
Published: April 2015

Purpose– The purpose of this study was to examine the effects of living in “green” dorms on students’ environmentally responsible behaviors (ERBs), in concert with other factors, including individual identity and social context in the form of behavior modeling by peers.Design/methodology/approach– The sample of 243 consists of students who resided in two newly constructed, Leadership in Energy and Environmental Design Gold-certified dorms and two conventional dorms. The authors analyze the data collected at the end of the respondents’ freshmen year at Emory University using seemingly unrelated regression analysis.Findings– Findings indicate that students who live in “green” dorms engage in more recycling and advocacy behaviors than students in conventional dorms. Environmental identity and perceived behavior modeling by peers positively affect recycling, advocacy and conservation. Furthermore, results indicate an interaction between dorm and identity whereby students with weak environmental identities experience a greater increase in ERBs from living in green dorms than do students with strong environmental identities.Practical implications– These results show that universities do promote students’ ERBs through the construction of green residence halls. Universities can also facilitate ERBs by encouraging students to develop strong environmental identities and fostering opportunities for them to engage in ERBs with their peers.Originality/value– This study is valuable for both its practical implications and the theoretical implications for predicting ERBs. The findings indicate that to predict ERBs, it is necessary to consider both contextual and individual level factors.
A method for detecting local events using the spatiotemporal locality of microblog posts
Authors: Sugitani Takuya , Shirakawa Masumi , Hara Takahiro , Nishio Shojiro 
Published: April 2015

Purpose
– The purpose of this paper is to propose a method to detect local events in real time using Twitter, an online microblogging platform. The authors especially aim at detecting local events regardless of the type and scale.

Design/methodology/approach
– The method is based on the observation that relevant tweets (Twitter posts) are simultaneously posted from the place where a local event is happening. Specifically, the method first extracts the place where and the time when multiple tweets are posted using a hierarchical clustering technique. It next detects the co-occurrences of key terms in each spatiotemporal cluster to find local events. To determine key terms, it computes the term frequency-inverse document frequency (TFIDF) scores based on the spatiotemporal locality of tweets.

Findings
– From the experimental results using geotagged tweet data between 9 a.m. and 3 p.m. on October 9, 2011, the method significantly improved the precision of between 50 and 100 per cent at the same recall compared to a baseline method.

Originality/value
– In contrast to existing work, the method described in this paper can detect various types of small-scale local events as well as large-scale ones by incorporating the spatiotemporal feature of tweet postings and the text relevance of tweets. The findings will be useful to researchers who are interested in real-time event detection using microblogs.
A semantic integration approach to publish and retrieve ecological data
Authors: Moura Ana Maria de Carvalho , Porto Fabio , Vidal Vania , Magalhães Regis Pires , Maia Macedo , Poltosi Maira , Palazzi Daniele 
Published: April 2015

Purpose
– The purpose of this paper is to present a four-level architecture that aims at integrating, publishing and retrieving ecological data making use of linked data (LD). It allows scientists to explore taxonomical, spatial and temporal ecological information, access trophic chain relations between species and complement this information with other data sets published on the Web of data. The development of ecological information repositories is a crucial step to organize and catalog natural reserves. However, they present some challenges regarding their effectiveness to provide a shared and global view of biodiversity data, such as data heterogeneity, lack of metadata standardization and data interoperability. LD rose as an interesting technology to solve some of these challenges.

Design/methodology/approach
– Ecological data, which is produced and collected from different media resources, is stored in distinct relational databases and published as RDF triples, using a relational-Resource Description Format mapping language. An application ontology reflects a global view of these datasets and share with them the same vocabulary. Scientists specify their data views by selecting their objects of interest in a friendly way. A data view is internally represented as an algebraic scientific workflow that applies data transformation operations to integrate data sources.

Findings
– Despite of years of investment, data integration continues offering scientists challenges in obtaining consolidated data views of a large number of heterogeneous scientific data sources. The semantic integration approach presented in this paper simplifies this process both in terms of mappings and query answering through data views.

Social implications
– This work provides knowledge about the Guanabara Bay ecosystem, as well as to be a source of answers to the anthropic and climatic impacts on the bay ecosystem. Additionally, this work will enable evaluating the adequacy of actions that are being taken to clean up Guanabara Bay, regarding the marine ecology.

Originality/value
– Mapping complexity is traded by the process of generating the exported ontology. The approach reduces the problem of integration to that of mappings between homogeneous ontologies. As a byproduct, data views are easily rewritten into queries over data sources. The architecture is general and although applied to the ecological context, it can be extended to other domains.
Examining the influence of corporate governance on intellectual capital efficiency
Authors: Appuhami Ranjith , Bhuyan Mohammed 
Published: April 2015

Purpose– The purpose of this paper is to examine the influence of corporate governance on intellectual capital (IC) in top service firms in Australia.Design/methodology/approach– Drawing on the agency theory, the paper develops hypotheses about relationships between corporate governance mechanisms (chief executive officer [CEO] duality, board size, board composition and subcommittee composition) and IC. The study uses a multiple regression analysis on data collected from corporate annual reports of 300 firm-year observations.Findings– The findings of the regression analysis indicate that CEO duality, board composition and remuneration committee composition are significantly associated with IC. In contrast, there is no evidence that board size and audit committee composition have an effect on IC. The study contributes to agency theory in general and the literature on IC and corporate governance more specifically.Practical implications– The findings of the study might be of interest to regulators, investment analysts, shareholders, company directors and managers in Australia, as well as academics, in designing corporate governance mechanisms to develop IC.Originality/value– Corporate governance is country-specific and, hence, its impact on managerial decisions leading to IC is different from country to country. This study provides empirical evidence on the relationship between corporate governance and IC in top service firms in Australia.
Did Japanese-SOX have an impact on earnings management and earnings quality?
Authors: Nakashima Masumi , Ziebart David A. 
Published: April 2015

Purpose– The purpose of this paper is to investigate whether Japanese Sarbanes – Oxley Act (J-SOX) impacted earnings management and earnings quality of public firms in Japan.Design/methodology/approach– This archival study compares earnings management and earnings quality of firms that disclose at least one material weakness with a sample matched on size and industry without a material weakness.Findings– The authors investigate whether the differences in regulations, corporate governance and regulatory environment acceptance influence earnings management and earnings management of Japanese listed firms, relative to findings in the USA. They found the Japanese results to be slightly different from the results found in previous USA studies. First, the time-series observations suggest that while accruals management and real earnings management remained unchanged for control firms, accruals management and real earnings management increased for material weaknesses disclosing firms following J-SOX. The regression analyses suggest that accruals management for both the groups is significant in the pre-and post-J-SOX periods, but that real earnings management declined for both the groups post-J-SOX. Second, while, both accruals quality and accuracy of cash flow predictions improved in the post-J-SOX period.Research limitations/implications– The sample of Japanese firms disclosing a material weakness is small because the number of firms that disclose internal control deficiencies is decreasing in Japan. The authors have no evidence that their results are not generalizable to a larger sample and leave this for future research.Practical implications– The authors provide evidence that J-SOX, which does not have a direct reporting system, does not constrain earnings management. Their results drive the regulator to reconsider whether the reporting system works in the Japanese business environment. Additionally, their results show that J-SOX has no effect on earnings management; thus, regulators need to reconsider the governance function of directors and internal auditors. This paper communicates to the world how J-SOX works in Japan through changes in earnings quality and management post J-SOX and the root problems.Originality/value– This paper is the first (of which the authors are aware) to examine whether J-SOX impacted both earnings management and earnings quality in Japan. This paper discusses how the differences in regulations and corporate governance as well as the differences between USA-SOX and J-SOX may explain the results observed in Japan. This paper provides results regarding whether J-SOX improved earnings quality.
Return transmissions between ADRs and A-shares of dual-listed Chinese firms
Authors: Wu Congsheng , Chen Ke 
Published: April 2015

Purpose
– A number of Chinese firms have dual-listed in USA and China. The US listing takes the form of American Depositary Receipts (ADRs) whereas the China listing in the form of A-shares. Though ADRs and their underlying A-shares lack full fungibility due to regulatory constraints, they nevertheless represent the same claiming rights and hence should be affected by the same fundamentals or news. The purpose of this paper is to examine the mutual return influences between ADRs and A-shares of dual-listed Chinese firms, and whether and how the recent global financial crisis has altered the mutual feedback dynamics.

Design/methodology/approach
– The paper uses the bivariate VAR approach to model the returns of ADRs and A-shares. The model is jointly estimated with the three-stage least squares (3SLS) method. It also accounts for the non-synchronous trading problem caused by the fact that the Chinese and US markets are located in different time zones and that the two market observe different national and religious holidays.

Findings
– The authors find significant mutual return transmissions between ADRs and their A-share counterparts. In the absence of local market sentiments, the return transmission is more prevalent going from USA to China than it is the other way around. After the market factors are included in the models, the information flows between A-shares and ADRs become stronger and bidirectional. Additionally, both ADR and A-share returns are strongly affected by the market sentiment of the marketplace where they are traded. Lastly, the authors find evidence showing that the recent global financial crisis has enhanced the linkage between ADRs and their underlying A-shares.

Originality/value
– This paper adopts a more rigorous approach to overcome the potential issue caused by non-synchronous trading. It investigates how the global financial crisis has altered the ADR and A-share return feedback dynamics.
What happens when a stock is added to the Nasdaq-100 index? What doesn’t happen?
Authors: Yu Susana , Webb Gwendolyn , Tandon Kishore 
Published: April 2015

Purpose
– Prior research on additions to the S
&
P 500 and the smaller MidCap 400 and SmallCap 600 indexes reach different conclusions regarding the key variables that explain the cross-section of announcement period abnormal returns. Most notable in this regard is that liquidity measures, long thought to be of importance, do not appear to explain abnormal returns of the S
&
P 500 when other factors are controlled for. By contrast, they do appear to matter for additions to the smaller stock indexes. To explore this difference, the purpose of this paper is to analyze the abnormal returns upon announcement that a stock will be added to the Nasdaq-100 Index in a cross-sectional manner, controlling for several possible alternative factors.

Design/methodology/approach
– This paper analyzes abnormal returns upon announcement that a stock will be added to the Nasdaq-100 Index. The authors consider several possible sources of the positive price effects in a multivariate setting that controls simultaneously for measures of liquidity, arbitrage risk, operating performance and investor interest and awareness. The authors then analyze both trading volume and the bid-ask spreads. The authors finally examine analyst and investor interest, focussing on changes in analyst coverage.

Findings
– The authors find that only liquidity variables are significant, but that factors representing feedback effects on the firm’s operations and level of managerial effort are not. The authors find that the average bid/ask spreads of stocks added to the Nasdaq-100 index are lower after the addition. The authors also find that the number of analysts following a stock increases significantly after addition, verifying increased analyst interest. Both forms of evidence are consistent with the hypothesis that the additions are associated with enhanced liquidity for the stocks.

Originality/value
– The authors conclude that what does happen to a Nasdaq stock when it is announced that it will be added to the Nasdaq-100 Index is that more analysts are drawn to it, and its market liquidity is enhanced. The authors conclude that what does not happen is that there is no evidence of significant effects of enhanced managerial effort or operating performance associated with the inclusion. This difference is noteworthy because it suggests that a certification effect of additions to the S
&
P indexes associated with S
&
P’s selection process are unique to it and do not apply to the Nasdaq-100 Index additions based on market cap alone. The results provide indirect evidence on the existence and significance of the certification effect associated with additions to the S
&
P indexes.
The interrelationships among default risk, capital ratio and efficiency
Authors: Nguyen Thanh Pham Thien , Nghiem Son Hong 
Published: April 2015

Purpose
– The purpose of this paper is to examine the interrelationships among default risk, capital and efficiency of the Indian banking system over 1990-2011. This study also took into account the impact of ownership on these interrelationships

Design/methodology/approach
– This paper employed Data Envelopment Analysis (DEA) Windows Analysis to estimate efficiency levels and trends of individual banks. This paper then used a model of seemingly unrelated regression equations (SURE) to examine the interrelationships among default risk, capital and efficiency.

Findings
– This study found a two-way negative association between efficiency and default risk, and between capital ratio and default risk. However, this study found a two-way positive relationship between capital ratio and only profit efficiency. Public banks behaved differently from private banks regarding the association between capital and efficiency. Moreover, public banks had greater probability of default risk, lower capital ratio but higher efficiency level than private banks. Further, default risk, capital ratio and efficiency of the Indian banking system increased over time, but the two formers were driven by public banks while the latter was driven by private banks.

Practical implications
– The findings of this study appear to favour capital ratio as an efficient tool to improve efficiency and reduce default risk of the Indian banking system.

Originality/value
– This paper is the first investigating the interrelationships between bank risk, capital and efficiency of the Indian banking system, where bank risk is measured by Z-score value and efficiency is captured by cost, revenue and profit efficiencies, and then considering the impact of agency issues on these interrelationships.
