Authors: Kim Stephen , Hamerski Chris , Ghassemi Kourosh , Shah Janak , Bhat Yasser , Klapman Jason , Komanduri Sri , Keswani Rajesh N. , Bidari Kiran , Wani Sachin , Watson Rabindra R. , Muthusamy Venkataraman R. 
Published: October 2015

Background:
The clinical utility of performing esophagogastroduodenoscopy (EGD) before linear endoscopic ultrasonography (L-EUS) to evaluate the luminal upper gastrointestinal (GI) tract is not well established.

Goals:
The study was aimed to determine the prevalence of clinically meaningful luminal abnormalities (any luminal finding requiring further evaluation with mucosal biopsy or initiation of treatment) in patients undergoing L-EUS. The study also sought to compare the ability of the gastroscope and the linear echoendoscope in identifying these lesions.

Study:
A prospective, multicenter cohort study enrolled patients undergoing L-EUS for nonluminal indications. All patients underwent EGD followed by L-EUS by 2 different endoscopists. The second endoscopist was blinded to the results of the initial EGD. The identification of clinically meaningful luminal lesions and quality of endoscopic visualization of the upper GI tract were measured.

Results:
In the cohort of 175 patients, 52 (29.7%) patients had clinically meaningful luminal findings seen in the upper GI tract. There was no significant difference in the number of clinically meaningful lesions identified on EGD and L-EUS (25.1% vs. 22.9%, P=0.39). No significant difference was found in the miss rate of clinically meaningful lesions between the 2 modalities (EGD: 4.5% vs. EUS: 6.9%, P=0.39).

Conclusions:
A substantial minority of patients undergoing L-EUS for nonluminal indications will have clinically meaningful luminal findings. The endoscopic evaluation of the luminal upper GI tract can be adequately achieved using the linear echoendoscope.
“The AYA Director”: A Synthesizing Concept to Understand Psychosocial Experiences of Adolescents and Young Adults With Cancer
Authors: Belpame Nathalie , Kars Marijke C. , Beeckman Dimitri , Decoene Elsie , Quaghebeur Marijke , Van Hecke Ann , Verhaeghe Sofie 
Published: October 2015

Background:
Adolescents and young adults with cancer face distinct psychosocial challenges because of the multiple developmental tasks associated with their age. Research on psychosocial care, directed to the unique needs and demands of this population, is limited.

Objective:
The aim of this study was to describe the psychosocial experiences of adolescents and young adults with cancer to further the understanding of the meanings they attribute to their experiences.

Intervention/Methods:
This study used a qualitative design in which individual semistructured interviews were conducted with 23 participants aged 15 to 25 years.

Results:
Physical consequences of the disease and its treatment, loss of independence, and being alone were significant challenges. Major coping strategies of the participants were to avoid the possible threats to life and maintain a positive attitude and normal life. Participants were “directors” who took control in order to manage their illness, maintain a sense of control, and master their lives to the fullest extent possible.

Conclusions:
The concept of the “AYA (adolescent and young adult) director” provides insight for healthcare professionals to understand how adolescents and young adults experience cancer.

Implications for Practice:
Throughout the cancer experience, participants wanted to be treated as individuals with specific needs and preferences. They preferred circumstances they are accustomed to; some found it difficult to accept restrictions imposed by the hospital. Adolescents and young adults with cancer want to be involved in the way healthcare professionals communicate with them and the information they are provided.
AOP: An R Package For Sufficient Causal Analysis in Pathway-based Screening of Drugs and Chemicals for Adversity
Authors: Burgoon Lyle D. 
Published: October 2015

ABSTRACTSummaryHow can I quickly find the key events in a pathway that I need to monitor to predict that a/an beneficial/adverse event/outcome will occur? This is a key question when using signaling pathways for drug/chemical screening in pharmacology, toxicology and risk assessment. By identifying these sufficient causal key events, we have fewer events to monitor for a pathway, thereby decreasing assay costs and time, while maximizing the value of the information. I have developed the “aop” package which uses back-door analysis of causal networks to identify these minimal sets of key events that are sufficient for making causal predictions.Availability and ImplementationThe source for the aop package is available online at Github athttps://github.com/DataSciBurgoon/aopand can be installed using the R devtools package. The aop package runs within the R statistical environment. The package has functions that can take pathways (as directed graphs) formatted as a Cytoscape JSON file as input, or pathways can be represented as directed graphs using the R/Bioconductor “graph” package. The “aop” package has functions that can perform backdoor analysis to identify the minimal set of key events for making causal predictions.Contactlyle.d.burgoon@usace.army.mil
Robust Group Fused Lasso for Multisample CNV Detection under Uncertainty
Authors: Noghabi Hossein Sharifi , Mohammadi Majid 
Published: October 2015

AbstractOne of the most important needs in the post-genome era is providing the researchers with reliable and efficient computational tools to extract and analyze this huge amount of biological data, in which DNA copy number variation (CNV) is a vitally important one. Array-based comparative genomic hybridization (aCGH) is a common approach in order to detect CNVs. Most of methods for this purpose were proposed for one-dimensional profile. However, slightly this focus has moved from one- to multi-dimensional signals. In addition, since contamination of these profiles with noise is always an issue, it is highly important to have a robust method for analyzing multi-sample aCGH data. In this paper, we propose Robust Grouped Fused Lasso (RGFL) which utilizes the Robust Group Total Variations (RGTV). Instead of l2,1norm, thel1-l2M-estimator is used which is more robust in dealing with non-Gaussian noise and high corruption. More importantly, Correntropy (Welsch M-estimator) is also applied for fitting error. Extensive experiments indicate that the proposed method outperforms the state-of-the art algorithms and techniques under a wide range of scenarios with diverse noises.
The value relevance of exploration and evaluation expenditures
Authors: Zhou Teng , Birt Jacqueline , Rankin Michaela 
Published: October 2015

Purpose
– This paper aims to investigate the value relevance of the various components of exploration and evaluation expenditures in the Australian extractives industry. Whether exploration and evaluation expenditures is more value relevant, following the adoption of AASB 6, and whether it differs for firms engaged only in exploration when compared to those also engaged in mining production is also examined.

Design/methodology/approach
– This paper uses a modified Ohlson model as a benchmark against which to compare an alternative valuation model featuring the disclosed components of exploration and evaluation expenditures. A sample comprising 430 firm-year observations between 2003 and 2009 is utilised.

Findings
– Written-off exploration and evaluation expenditures and the number of projects in which firms are involved is relevant to investors when assessing the value of extractive firms. Further, the implementation of AASB 6 has led to an improvement in the relevance of exploration and evaluation information in assessing firm value.

Research limitations/implications
– The sample is based on observations from the years 2003-2004 to the years 2006-2009. The authors do not incorporate 2005, as this is the first year the new standard was implemented, and there is the possibility of a settling in effect. The authors base our sample on the top 100 extractive firms in 2009. As such, these companies may not represent the accounting practices of smaller firms in the Australian extractive industry.

Originality/value
– The authors address a gap in the literature by examining the value relevance of the detailed line items of exploration and evaluation expenditure reported by extractives firms. The authors also explore the effect of regulatory changes by examining the value relevance of exploration and evaluation expenditures pre- and post-International Financial Reporting Standards (IFRS) 6/Australian Accounting Standards Board (AASB) 6 implementation. Finally, the authors contribute useful findings to the standard setters’ ongoing deliberations aimed at producing a comprehensive standard on extractive activities by providing useful feedback on the relevance of accounting for pre-production costs under a regime using the “area of interest” method.
The effects of comprehensive income on investors’ judgments
Authors: Du Ning , Stevens Kevin , McEnroe John 
Published: October 2015

Purpose
– This paper aims to understand the effects of different presentation formats on nonprofessional investors’ judgments. Both International Financial Reporting Standards and US Generally Accepted Accounting Principles require an entity to present items of net income and other comprehensive income (OCI) either in one continuous or in two separate, but consecutive, statements but limited understanding exists about their differential effects on evaluation of company performance.

Design/methodology/approach
– To investigate this research question, we used a two (Financial Position) x two (Format) randomized between-subjects experiment. Ninety-four graduate students assumed the role of investor and participated in this study.

Findings
– Results of the experiment suggest that participants are more likely to incorporate OCI information presented in the one-statement format than in the two-statement format. Further analysis suggests that participants both assign more weight to OCI and perceive OCI to be relatively more important in the one-statement format than in the two-statement format, especially when the entity suffers an economic loss.

Originality/value
– Results from this study provide evidence to the Financial Accounting Standards Board and International Accounting Standards Board that should be useful in evaluating the effectiveness of alternative comprehensive income reporting formats and should be of interest to accounting rule-making bodies, investors, publicly traded entities and financial analysts, among others.
Book-tax differences: are they affected by equity-based compensation?
Authors: Xian Chunwei , Sun Fang , Zhang Yinghong 
Published: October 2015

Purpose
– This study aims to investigate the moderating effect of equity-based compensation on the sources of book-tax differences. The authors investigate whether equity-based compensation affects the association between book-tax differences and tax planning, and the association between book-tax differences and earnings management.

Design/methodology/approach
– The authors use a sample of 9,024 firm-year observations (913 firms) spanning the period 1992-2011, obtained from ExecuComp and Compustat. They estimate cross-sectional regressions of the proxy for tax planning, discretionary accruals and their interactions with equity-based compensation on book-tax differences.

Findings
– The authors find that tax planning-related book-tax differences increase as the equity-based pay of executives does, and that earnings management-related book-tax differences decrease as the equity-based pay of executives increases. The results are robust across three alternative measures of tax planning.

Originality/value
– Equity-based compensation plays an important role in managerial discretion on tax planning and earnings management. The findings suggest that, although equity incentives promote a high level of both tax planning and earnings management, they motivate managers to constrain the level of earnings management to avoid larger book-tax differences.
The growing pressures on Groupon's once-successful daily deal business
Authors: Miu Yee Cathy Leung 
Published: October 2015

Subject area
Marketing Management, Business Strategy and Promotion & Advertising.

Study level/applicability
Associated degree, undergraduate and graduate students as well as executives from profit-making organizations.

Case overview
Groupon is the world's largest daily-deal Web site and a pioneer in the group-buying industry. The major feature of the company's business model is that merchants use Groupon as a platform to offer coupons with a discounted price, and the coupon buyers can then redeem these coupons. Groupon has done business in over 50 countries and, by 2012, had over 39.5 million subscribers received its daily news. It had a 59.1 per cent share of the daily-deals market in 2013. Groupon is a publicly listed company on the NASDAQ in the USA, trading under the ticker symbol of “GPRN”.

Expected learning outcomes
The students' business knowledge and skills will be sharpened by working through this case, and students will be challenged to identify solutions to the marketing concerns: specifically, how the driving approach of its daily-deal business model enabled the company to adopt a growth strategy that will confront the difficulties of the emergent “golden age” of the daily-deal industry in the twenty-first century. In addition, it will also be of help to the students to take the active roles of thinker, analyst, evaluator, decision-maker and implementer to evaluate the continuing changes in a competitive environment and consider how Groupon can seize available opportunities to predict future performance by comparing data from 2008 and 2012.

Computer education and societal change
Authors: Tatnall Arthur 
Published: October 2015

Purpose
– It is widely acknowledged that the computer has caused great societal changes over recent years, but the purpose of this paper is to relate specifically to those due to the use of computers in education and teaching about computing. The adoption and use of computers in education was very much a socio-technical process with influence from people, organisations, processes and technologies: of a variety of human and non-human actors.

Design/methodology/approach
– This paper makes use of actor-network theory to analyse these events and their educational and societal impact. Data were collected from published sources, interviews with those involved at the time, discussions and from personal experience and observations.

Findings
– Computers have, of course, had a huge impact on society, but particularly in relation to the use of computers in school education there was a different societal impact. Some of this related directly to education, some to school administration and some to student attitudes, experiences and knowledge.

Research limitations/implications
– The paper investigates the development of early courses in computing in universities and schools in Victoria, Australia. The paper does not, however, consider the use of computers in university research, only in education.

Practical implications
– The paper describes the significant educational events of the era from punch-card tabulating machines in the 1930s to micro-computers in the late 1980s, and investigates the relationship between the development of courses in the Universities and those in the more vocationally oriented Colleges of Advanced Education. It examines whether one followed from the other. It also investigates the extent of the influence of the universities and CAEs on school computing.

Social implications
– The advent of the computer made a significant impact on university and school education even before the internet, Google, Wikipedia and smart phones in the late 1990s and 2000s. Computers in schools cause a rethink of how teaching should be handled and of the role of the teacher.

Originality/value
– This paper investigates the history of computers and education in both universities and schools in Victoria, Australia over the period from the 1930s to the early 1990s. It considers how and why this technological adoption occurred, and the nature of the resulting educational and societal change this produced. Primary and High School use of computers did not commence until the 1970s but prior to this there is a considerable and interesting history associated with the development of Higher Education courses relating to computing.
ICT and environmental sustainability in a changing society
Authors: Lennerfors Thomas Taro , Fors Per , van Rooijen Jolanda 
Published: October 2015

Purpose– The purpose of this paper is to discuss the role of information and communication technology (ICT) for promoting environmental sustainability in a changing society. Isolated studies exist, but few take a holistic view. Derived from a Marxian tradition, the authors propose Ecological World Systems Theory (WST) as a holistic framework to assess the environmental impact of ICT. The theory is adapted responding to theoretical critiques of absence of change, namely state-centrism and structuralism.Design/methodology/approach– Theoretical study. Empirical examples derived from already published literature.Findings– Ecological WST focuses on the unequal distribution of environmental degradation, sees technological development as a zero-sum game rather than cornucopia and holds that technology is often seen as a fetish in today ' s society. The findings are that popular discourses on ICT and sustainability are since the 1990s becoming increasingly cornucopian, while conditions in the ICT value chain are less cornucopian.Research limitations/implications– Theoretical contributions to Marxian critiques of ICT, with more environmental focus than earlier Marxian critiques, for example Fuchs’ work. Develop a theoretical framework for ICT and sustainability which could be compared with works of e.g. Hilty, Patrignani and Whitehouse. The work is mostly based on existing empirical studies, which is a limitation.Practical implications– This theoretical framework implies that unequal environmental degradation in different parts of the world should be taken into account when assessing environmental impact, for example by means of LCA.Social implications– The framework brings together questions of environmental effects of ICT and global justice.Originality/value– The authors apply a rarely discussed theoretical framework to ICT and environmental sustainability. By doing this the authors suggest how the discourses and the value chain of ICT is intrinsically tied to the world system.
Theorising Web 3.0: ICTs in a changing society
Authors: Kreps David , Kimppa Kai 
Published: October 2015

Purpose– The purpose of this paper is to analyse the broad phases of web development: the read-only Web 1.0, the read-write Web 2.0, and the collaborative and Internet of Things Web 3.0, are examined for the theoretical lenses through which they have been understood and critiqued.Design/methodology/approach– This is a conceptual piece, in the tradition of drawing on theorising from outside the Information Systems field, to shed light on developments in information communication technologies (ICTs).Findings– Along with a summary of approaches to Webs 1.0 and 2.0, the authors contend that a more complex and poststructuralist theoretical approach to the notion of, and the phenomenon of Web 3.0, offers a more interesting and appropriate theoretical grounding for understanding its particularities.Originality/value– The discussion presages five further papers engaged with ICTs in a changing society, each of which similarly addresses novel theoretical understandings.
Relations of fit and organizational identification to employee-customer identification
Authors: Anaza Nwamaka A. 
Published: October 2015

Purpose
– The purpose of this paper is to examine a model of employee-customer identification (ECID) using two samples: nurses and cooperative extension frontline employees. The model posits that person-organization fit, person-job fit, and organizational identification are positively related to ECID.

Design/methodology/approach
– A recursive path-based structural model was employed to test seven hypotheses regarding the relationships between the two fit constructs, organizational identification, and ECID.

Findings
– In both samples, person-organization fit and person-job fit were positively related to organizational identification, and organizational identification was positively related to ECID. In the cooperative extension sample, person-job fit was positively related to ECID. Person-job fit was also indirectly related to ECID through organizational identification in both samples.

Research limitations/implications
– The results imply an important relationship between person-job fit and ECID that could be useful for improving service encounters between employees and customers. In addition, an emphasis on organizational identification may also contribute to improved employee-customer relationships.

Originality/value
– This study represents one of the first attempts to demonstrate a link between person-job and person-organization fit on ECID. The results of this study provide support for organizational identification and person-job fit as important factors in employee-customer relationships.
