Making sense of Enterprise 2.0
Authors: Gardner Ben 
Published: May 2013

PurposeThe purpose of this paper is to demonstrate how the capabilities of Enterprise 2.0 tools align to the tasks knowledge workers perform. The objective is to provide knowledge workers and information architects with a framework that enables the development of a suite of Enterprise 2.0 tools in support of knowledge management across the full knowledge lifecycle.Design/methodology/approachThe capabilities of Enterprise 2.0 tools were mapped against the requirements associated with each of the four main domains (chaotic, complex, knowable and known) of the Cynefin framework.FindingsThe Cynefin model provides a useful framework for illustrating how the various tools within an Enterprise 2.0 suite support the different activities/tasks knowledge workers perform. Aligning Enterprise 2.0 tools based on the domain requirements of the Cynefin model allows the classification of these capabilities based on a task‐based framework rather than the traditional feature/function‐based ones.Practical implicationsApplication of this framework will help knowledge workers and information architects understand the relationship between technical capabilities and business tasks. This understanding will help both in tool selection with respect to business problem (architects) and also provide clarity of purpose in support of change management/adoption (knowledge workers).Originality/valueMuch of the literature around understanding Enterprise 2.0 tools has focused on a classical feature/function classification. The analysis presented here provides a classification based on the Cynefin model of knowledge creation. This classification model provides a valuable tool to those interested in developing environments that enable collaboration and knowledge generation/capture using these capabilities.
Learning at transition for new and experienced staff
Authors: Milligan Colin , Margaryan Anoush , Littlejohn Allison 
Published: May 2013

PurposeThis study aims to improve the understanding of the learning and development that occurs during initial and subsequent role transitions within knowledge intensive workplaces.Design/methodology/approachSemi‐structured interviews were conducted with 19 knowledge workers in a multinational company and the learning experiences of new graduates contrasted with those of more experienced workers who had recently joined or changed role within the organization.FindingsGraduate recruits and more experienced workers utilise a similar range of learning approaches, favouring a combination of traditional formal learning, learning by doing and learning with and from others, but differ in the precise modes and strategies used. It was found that graduate induction provides appropriate support for initial transition into the workplace, but that experienced workers undergoing subsequent career transitions do not receive similar socialization support despite encountering similar challenges.Research limitations/implicationsThis study brings concepts and literature from two distinct research traditions together to explore learning during transition. In doing so, the impact of organizational socialization strategies as a mechanism by which an environment to support rich learning is created can be seen. The study was exploratory in nature, examining only one organization and studying a relatively small group of workers.Originality/valueWhile employee induction has been studied in detail, the learning occurring at this time, and particularly during subsequent career transitions, is less well understood. This article is of value to those investigating learning in knowledge intensive workplaces, as well as human resource managers responsible for socialization of employees entering new roles.
Goodwill accounting and asymmetric timeliness of earnings
Authors: Kim Sohyung , Lee Cheol , Wook Yoon Sung 
Published: May 2013

PurposeThe purpose of this paper is to investigate how fair value reporting and increased managerial discretion under the new goodwill accounting affect the asymmetric timeliness of earnings;, i.e. accounting conservatism.Design/methodology/approachVarious empirical models are applied to a sample of 11,034 firms. To capture a cross‐sectional variation in asymmetric timeliness of earnings, Kahn and Watts' C_Score is adopted.FindingsIt is found that financial reporting for firms with purchased goodwill has become more conservative after the enactment of the new standard. However, once an increase in conservatism that is not attributable to new goodwill accounting is controlled for, it is found that accounting earnings for firms with purchased goodwill become less conservative.Research limitations/implicationsThe results should be interpreted with caution, because the effect of concurrent events other than the adoption of SFAS 142 on reported earnings is not perfectly controlled.Practical implicationsThe results of this paper support Watts' assertion that new goodwill accounting impairs accounting earnings' ability to reflect the economic earnings in a timely manner, but these results should be interpreted with caution, as the main objective of goodwill accounting is not to improve accounting conservatism.Originality/valueThis paper makes a timely contribution to the debate of fair value accounting by focusing on the impact of SFAS 142 on the asymmetric timeliness of earnings. By employing all available firms with purchased goodwill balances rather than relying on firms that report impairment losses, our research design better captures the impact of SFAS 142 on financial reporting.
“6 and 1” option exchanges and stockholder wealth
Authors: Gupta Atul 
Published: May 2013

PurposeFirms will, at times, replace employee holdings of out‐of‐the‐money stock options with new ones that have lower exercise prices. This paper seeks to examine how stockholders view such actions.Design/methodology/approachThe stock price reaction to announcements of option exchange programs is used to establish how stockholders view option exchanges. Regression analysis is then used to get insight into firm and program characteristics that explain cross‐sectional differences in the stock price response.FindingsA positive stock price response indicates that stockholders view such option exchanges as value enhancing. Regression analysis indicates that the price response increases with a firm's growth opportunities, the level of employee turnover, the extent to which employee option holdings are out‐of‐the‐money, and the quality of corporate governance. Deals where only non‐executive employees are allowed to participate are viewed more favourably.Originality/valueThis is the first paper to document that stockholders regard resetting the terms of employee option holdings in a positive vein, confirming implications emerging from theoretical papers on this subject. The paper also documents firm and program characteristics that impact the extent of possible value creation.
Momentum profits and idiosyncratic volatility: the Korean evidence
Authors: Pyo Unyong (Howard) , Jae Shin Yong 
Published: May 2013

PurposeThis study aims to focus on the profitability of momentum trading in the Korean stock market. More specifically, it aims to conduct an examination of the relationship between momentum returns and idiosyncratic volatility (IVol) to determine whether momentum profits can be explained by IVol.Design/methodology/approachPortfolios are formed based on their past performance and examine the momentum, or contrarian returns, as the difference between winning and losing portfolios. To confirm that the momentum strategy provides excess returns, the relationship between momentum returns and IVol is studied. The Fama and French three‐factor model is also examined to see whether systematic risk affects momentum profits. Firm size, stock price, and turnover are controlled to determine robustness. Finally, a time‐series relationship between aggregate IVol and momentum profits is investigated.FindingsThe paper illustrates that excess returns are obtained from a momentum strategy, not a contrarian strategy, in the Korean stock market. Momentum returns are higher among high IVol stocks, especially high IVol winners. Examining the Fama and French three‐factor model, it is found that momentum returns cannot be explained by systematic risk. The findings are robust after controlling for factors such as firm size, book‐to‐market ratio, and turnover. The paper confirms the effect of IVol on momentum returns by illustrating that a time‐series relationship between momentum returns and aggregate IVol is positive.Originality/valueThis paper is among the first, to the authors' knowledge, to examine the relationship between momentum profits and IVol in the Korean stock market, one of the mature financial markets. The findings in this study can be applied to better understand the sources of gains from the momentum strategy in international stock markets.
From bricolage to thickness: making the most of the messiness of research narratives
Authors: Lambotte François , Meunier Dominique 
Published: May 2013

PurposeThe research process is commonly viewed as a succession of linear, structured and planned practices that exclude informal and unplanned practices, engaging with the unexpected or the uncertain. The authors’ aim is to explore this aspect of researching in connection with the narratives of researchers as they oscillate between past and present, theory and empiricism.Design/methodology/approachThe authors first draw on the concept of “bricolage” to validate informal research practices as researchers seek to lend “thickness” to their research. To deal with the apparent “messiness” of research narratives, they apply the concepts of kairotic time and action nets. Kairotic times are key moments in research narratives when actions, under tension, interconnect to form action nets, which, in turn, generate meaning or knowledge.FindingsThe authors analyse two research episodes. The first recounts how personal experiences and contingencies influence a researcher's choice of research objects and his associated theoretical reflections. The second highlights how some concrete difficulties in choosing a field and gaining access trigger a set of actions that force a researcher to review his initial choices and to reposition himself methodologically. Discussing the concept of kairotic time, the authors show the importance of context and timing and demonstrate how stories build around a gravitational point. From there, they discuss how the concept of action nets, breaking linearity, helps to envision research practice not as a sequence, but as networks of actions that produce scientific outcomes.Originality/valueThis paper provides an operational method of using kairotic time and action nets to account for, and acknowledge, the messiness in research narratives.
Untold stories of the field and beyond: narrating the chaos
Authors: Donnelly Paul F. , Gabriel Yiannis , Özkazanç‐Pan Banu 
Published: May 2013

PurposeThe Guest Editors’ intent with this special issue is to tell tales of the field and beyond, but all with the serious end of rendering visible the largely invisible. This paper aims to introduce the articles forming the special issue, as well as reviewing extant work that foregrounds the hidden stories and uncertainties of doing qualitative research.Design/methodology/approachThe authors advance their arguments through a literature review approach, reflecting on the “state of the field” with regard to doing research and offering new directions on reflexivity as an ethical consideration for conducting qualitative research.FindingsFar from consigning the mess entailed in doing qualitative research to the margins, there is much to be learned from, and considerable value in, a more thoughtful engagement with the dilemmas we face in the field and beyond, one that shows the worth of what we are highlighting to both enrich research practice itself and contribute to improving the quality of what we produce.Originality/valueThis paper turns the spotlight onto the messiness and storywork aspects of conducting research, which are all too often hidden from view, to promote the kinds of dialogues necessary for scholars to share their fieldwork stories as research, rather than means to a publication end.
Trade productivity upgrading, trade fragmentation, and FDI in manufacturing
Authors: Mora Jesse , Singh Nirvikar 
Published: May 2013

PurposeThis paper aims to examine the experience of ten Asian countries with respect to growth, trade and FDI. It seeks to explore relationships between the nature of exports and imports and growth, as well as the relevance of FDI as a channel for these relationships.Design/methodology/approachThe paper opted for an empirical approach. It included collecting standardize data on international trade, GDP per capita, and FDI inflows. The trade data and GDP data were used in creating the productivity level for exports and imports for all of the relevant countries. The paper analyses how these productivity levels compare to GDP per capita, change over time, and relate to FDI inflows.FindingsThe authors find that FDI is positively correlated with higher productivity levels in exports and imports for many of the countries in their sample. The effect for imports is particularly apparent for imported intermediate goods, reflecting the emergence of greater trade fragmentation. In turn, both imported intermediates and exports that are associated with higher productivity levels are positively correlated with per capita GDP.Research limitations/implicationsThere are a couple of research limitations. First, the work does not determine causality; future econometric work should help to identify the causality mechanism. Second, trade fragmentation might lead to an overestimation of “productivity” levels; future work should try to identify the extent of the bias and a way to fix the issue.Practical implicationsThis work may have implications for how policymakers view trade and FDI policies, and the possible links between them, in the context of promoting growth.Social implicationsThis work may have implications for understanding the links between growth and structural change in the economy, which is in turn linked to societal change.Originality/valueThis paper brings together empirical evidence that integrates discussions of FDI, trade fragmentation and improvements in the productivity of traded goods.
Globalization and inequality: insights from municipal level data in Brazil
Authors: Samy Yiagadeesen , Daudelin Jean 
Published: May 2013

PurposeThe relationship between globalization – through trade liberalization – and inequality is unclear. The Stolper‐Samuelson theorem, which is a standard result in trade theory, does not offer compelling answers as globalized economies with an abundance of unskilled labour have seen inequality both worsen, as in China and much of Asia, and improve, as in Latin America. Kuznets' classic model also finds scant confirmation in increasingly open economies, with growth associated with declining inequality in poorer Latin America, and with rising inequality in richer OECD countries. The authors aim to suggest that the key to those anomalies lies in the relative weight of industrialization in a country's growth mix.Design/methodology/approachUsing census data (for 1991 and 2000) for more than 5,000 municipalities, the authors examine the relationship between income per capita and inequality in Brazil.FindingsThe authors uncover the existence of an “inverted‐U” relationship in 1991 that flipped into a “straight‐U” relationship in 2000, both of which are statistically significant. They argue that the flip results from the association of economic growth with de‐industrialization that is driven by globalization.Research limitations/implicationsIn terms of future work, there is a need to examine further the role of de‐industrialization, not only in the case of Brazil but also other emerging economies with different patterns of inequality than the ones currently observed in Latin America and Brazil in particular.Practical implicationsThe authors' result reinforces the growing skepticism towards the role of industrialization in economic development, as Brazil sees its most successful period of pro‐poor growth go hand in hand with its de‐industrialization.Social implicationsThe authors' result casts doubts about the role of social policy in the current evolution of inequality and poverty in Brazil. The famous Bolsa Familia program, in particular, may have been exaggerated by both the Brazilian government and social policy specialists, as much of the change could be traced to changes in the structure of the economy itself.Originality/valueThis paper contributes to the existing literature on globalization and inequality. It uses municipal level data and identifies a “flip” in the Kuznets relationship. This enables us to make sense of growing inequality in poorer but industrializing economies and in rich ones going through processes of de‐industrialization, and also of declining inequality in poorer de‐industrializing countries such as Brazil.
Household life‐cycle asset allocation and background risk of labor income
Authors: Cai Mingchao , Zhao Jun , Pan Rulu , Huang Haozhi 
Published: May 2013

PurposeThe purpose of this paper is to empirically analyze the relationship between risky asset allocation and background risk of Chinese residents.Design/methodology/approachUsing Chinese macroeconomic data, this study uses numerical method to solve dynamic stochastic optimal problem.FindingsWhen risk of labor income is considered, ratio of risky asset declines with rising of age for those people with same age and wealth state; any of the following situations will lead to lower risky assets holdings: lower labor income growth expectations, higher labor income risk or higher labor and financial market covariance risk.Research limitations/implicationsThis study uses real economy investment return as a proxy of risky asset return.Practical implicationsResidents with higher background risks should hold less risky assets, and overcome home‐bias problem during asset allocation.Originality/valueThis study takes two kinds of background risk into consideration: labor income risk, and covariance between labor income and risk asset.
Role of Bisoprolol in Patients with Long QT Syndrome
Authors: Fazio Giovanni , Vernuccio Federica , Lo Re Giuseppe , Grutta Giuseppe , Mongiovì Maurizio 
Published: May 2013

BackgroundLong QT syndrome (LQTS) is a disorder of ventricular repolarization usually treated with β‐blockers, mostly with propanolol and nadolol. The aim of our study was to evaluate the role of bisoprolol in LQTS patients.MethodsA total of 34 patients were evaluated in an average follow‐up time of 93 months: 31 months without treatment, 31 months in treatment with nadolol or propanolol and 31 months in treatment with bisoprolol. The average age of patients at diagnosis was 17.3 years. The enrolled patients were followed through a semiannual electrocardiogram and an annual 24‐hour Holter monitoring. All patients underwent genotyping, routine hematologic tests, and an echocardiogram.ResultsIn 93 months there were 2 major and 12 minor cardiovascular events. Both the major events occurred in absence of β‐blocking therapy. Of the 12 minor cardiovascular events 3 occurred in absence of treatment, 7 during treatment with nadolol or propranolol, and 2 during treatment with bisoprolol. The mean heart rate at 24 h Holter was 87 bpm without treatment, 71 bpm in patients treated with propanolol and nadolol, and 70 bpm in patients treated with bisoprolol. There were not statistically significant differences between the three groups in the mean QTc.ConclusionsBeta‐blocking therapy is the cornerstone of LQTS therapy but actually there is no clear indication about which beta‐blocker should be used. In our experience bisoprolol proved to be less harmful and easier to manage than propranolol and nadolol in patients with LQTS, with the same effectiveness in preventing major cardiovascular events.
Simultaneous ventral hernia repair in bariatric surgery

Published: May 2013

AbstractBackgroundObesity is a significant risk factor in abdominal hernia occurrence and recurrence. In patients having bariatric surgery, there are no clear guidelines as to whether repair should be done simultaneously, especially if procedures involve division or resection of part of the gastrointestinal tract.MethodsA retrospective case series review over a 6‐year period to December 2012 from a prospective database was conducted. As per existing practice for bariatric procedures, patients were followed up indefinitely. Short‐ and long‐term outcomes were analysed.ResultsForty‐five patients underwent combined laparoscopic bariatric surgery and abdominal wall hernia repair. Of these, 36 had resection procedures (gastric bypass or sleeve gastrectomy) and 9 had non‐resection procedures (gastric banding). The mean operative time was 151 min and the mean length of stay was 3 days. Two patients developed post‐operative mesh seroma infections. To date, there have been no mesh removals or recurrent hernias. There was no mortality in this series.DiscussionThis study demonstrated a low rate of mesh infection (4.44%) at a median follow‐up of 13 months, even when a resectional procedure was performed (5.56%). These results suggest the possible viability and reasonable short‐/long‐term outcomes of simultaneous laparoscopic abdominal wall hernia repair during bariatric surgical procedures, even if the surgery involved division or resection of part of the gastrointestinal tract. This topic is an area of clinical research that warrants further study.
Formal examiner training reflects the increased expertise required of RACS examiners

Published: May 2013

AbstractThe Fellowship Examination is the final summative assessment before the Surgical Education and Training trainees are awarded Fellowship of the Royal Australasian College of Surgeons. Conducted in nine specialties, it is aligned with the curriculum of each specialty training programme. The Fellowship Examination focuses on specific surgical competencies; in particular, the clinical application of knowledge, operative decision making and professional judgement. As a true ‘exit’ examination, it has to be conducted at the correct cognitive level for surgeons about to enter practice without direct supervision. This requires examiners to have specific skills and expertise for which training is required. This paper outlines the process of training undertaken by newly appointed examiners, and describes some of the areas of knowledge that they have to master before examining at the consistently high level that is now expected.
