Teaching knowledge management by combining wikis and screen capture videos
Authors: Makkonen Pekka , Siakas Kerstin , Vaidya Shakespeare 
Published: November 2011

PurposeThis paper aims to report on the design and creation of a knowledge management course aimed at facilitating student creation and use of social interactive learning tools for enhanced learning.Design/methodology/approachThe era of social media and web 2.0 has enabled a bottom‐up collaborative approach and new ways to publish work on the web, promoted by tools such as YouTube video service. In this spirit a knowledge management course was designed aiming to facilitate university students to compose videos on different difficult concepts in the theory part of the course by searching for explanations on the web and by creating a Windows Media Player video focusing on the self‐defined problems. The videos created by the students were published on a wiki (Wetpaint) and the students were encouraged to actively share knowledge and learn from one another by familiarising themselves with the videos of the other students. In order to utilise cognitive and social constructivism, as well as problem‐based learning, the principles of the Jigsaw method were used to enable different students to create videos on different themes.FindingsBased on the authors' experiences it is suggested that curriculum and syllabus planning should be transformed toward a more student‐centred approach. This is the most natural in the context of knowledge management, which emphasizes the meaning of participation and knowledge sharing. The social constructivist learning theory emphasizes the meaning of interaction in successful learning. By publishing videos created by the students themselves, by commenting on videos created by other students and by reading comments expressed by others the approach proved to be beneficial for learning in many ways.Research limitations/implicationsThe research limitation lies in the differences of quality, format and sizes of these videos produced and the efforts and time requirements for editing and use.Practical implicationsThe present finding and report implies more of these resources could be generated by students in other courses in other study areas encouraging use of these types of resources, engaging students with the curriculum, and encouraging interaction amongst students promoting deeper understanding, more positive learning experiences and the generation of curriculum teaching materials by students for class work, making learning more student focused.Originality/valueThe paper focuses on a unique process that allows the use of social technology by students for the generation of materials for use in learning.
Wireless hazard communication system
Authors: Bhattacharya Devanjan , Ghosh Jayanta Kumar , Boccardo Piero , Samadhiya N.K. 
Published: November 2011

PurposeCommunication of an impending hazard to people in near real time is critical. The purpose of this paper is to develop an internet‐SMS based geo‐hazard warning communication system.Design/methodology/approachA warning system based on an internet‐resident concept and the available cellular mobile infrastructure is proposed in this study. The functionality of the system is modular in architecture.FindingsThe messages have been transmitted in a set of 20 SMSs six times, to locally‐owned mobile numbers, resulting in a total number of 120. It has been found that 58 messages got delivered within ten seconds, the rest within 40 more seconds. The threat messages reached the impending threat areas within acceptable time delay.Originality/valueThe paper describes the implementation of a novel and stand‐alone system for dynamic hazard warning. Cellular or mobile phone, a gadget used by common man, is expected to be the best proposition to effectively warn people individually and to propagate hazard messages to users in large regions ubiquitously. The concept allows pervasiveness and redundancy, important to withstanding hazards and bringing several original elements through the development of this “fast warning system”, as current warning strategies do not include such solutions.
An examination of the information content of S&P 500 index changes
Authors: Geppert John M. , Ivanov Stoyu I. , Karels Gordon V. 
Published: November 2011

PurposeThe purpose of this paper is to examine the shocks to firm's beta around the event of addition or deletion from the S&P 500 index.Design/methodology/approachThe total derivative of beta and Campbell and Vuolteenaho decomposition of beta methodologies are used, on monthly and daily basis, to examine the behavior of beta around the event.FindingsResults show a significant increase in correlations of the event firms' returns and the market proxy returns and cash‐flow betas, and decrease in discount‐rate betas for added firms and the opposite effects for deleted firms. Robustness tests indicate that the total derivative changes effects are typical for the event firms industry but that the cash‐flow correlation changes are specific to the firm. These findings suggest that addition or deletion from the S&P 500 index is not an information free event.Research limitations/implicationsThe Campbell and Vuolteenaho methodology has limitations – it is conditional on the selection of state variables. In future research it would be beneficial to use different state variables in the beta decomposition framework. Another relevant question for a future research is: what are the effects of the event on the Fama‐French factor model loadings?Originality/valueThe paper's findings contribute to the ongoing debate in the literature of the information hypothesis for addition or deletion from the S&P 500 index.
US macroeconomic news spillover effects on Vietnamese stock market
Authors: Nguyen Tho 
Published: November 2011

PurposeThe purpose of this paper is to investigate the spillover effect of the US macroeconomic news on the first two moments of the Vietnamese stock market returns.Design/methodology/approachThe author collected market expectation and actual announcements data for 12 key US macroeconomic announcements for the period from August 2000 to September 2009 from Bloomberg. The dataset consists of monthly Non‐farm payroll (NFPM), Unemployment level (UNEMP), Gross Domestic Product percentage level (GDP), Housing statistics (HOMEST), Industrial production (INDP), Leading Indicator (LEAD), Retail Sales (SALES), Consumer Price Index (CPI), Producer Index (PPI), Current Account (CA, quarterly), Trade Balance (BOT), and the Federal Reserve's target rates (FOMC, 8 times a year and ad hoc meetings if needed). The MA‐EGARCH (1,1) model is used for the empirical test of the US macroeconomic news spillover effects on the VNI index.FindingsIn general, the US real economic news has the strongest effect on the first two moments of the Vietnamese stock returns. This can be interpreted as evidence that Vietnamese market participants believe that the USA is targeting real economic activities other than other variables. It is also shown that even though the US stock market (proxied by S&P500 index) significantly affects the Vietnamese stock market returns, the spillover effect of the US macroeconomic news is still significant.Research limitations/implicationsThe author does not explore further on the transmission channels of the spillover effects of the US news on the Vietnamese stock market, reserving this task for future research.Originality/valueThe paper contributes to the extant literature in several ways. First, to the author's knowledge, the current literature lacks empirical evidence for the impact of the US macroeconomic news on the first two moments of the Vietnamese stock markets. Given the growing integration between the two economies, evidenced by the fact that the USA is Vietnam's largest foreign direct investor and importer, the US macroeconomic news is very important, not only for Vietnamese policy makers but also for market participants. Furthermore, the choice of a small and open market with increasing exposure to the world economy and vulnerable to the US news (i.e. Vietnam) would help in reducing the problem of endogeneity bias in previous studies employing large economy pairs, as the US news might affect the Vietnamese stock market but not the reverse. Finally, previous studies tend to investigate the impact of macro news only on conditional returns. In this study, both conditional returns and the conditional variance of returns are modelled simultaneously in a time‐varying framework (MA‐GARCH) to better capture the impact of macroeconomic news on stock returns and stock market volatility.
Modelling activity‐based costing in restaurants
Authors: Kostakis Hara , Boskou George , Palisidis George 
Published: November 2011

PurposeThis paper seeks to demonstrate an application of a methodology, which is based on the integration of three techniques, with the purpose of modelling activity‐based costing (ABC) in restaurants. The proposed methodology serves as a tool for effectively computing values of cost drivers in the restaurant industry, as well as making accurate cost estimations.Design/methodology/approachThe methodology is based on the integration of three techniques: simulation modelling, association rule mining (ARM) and ABC. Simulation modelling is used to model process variability and produce a range of cost values, instead of a point estimate of the cost, by generating a range of values for the simulated cost drivers. The advantage of the proposed methodology lies on the effective utilization of ARM in the ABC model; it extracts dependencies between a cost driver, whose estimation is time‐consuming, with another cost driver, which can easily be calculated. These associations can assist the estimation of the empirical distributions of those cost drivers, which were difficult to calculate.FindingsThe extracted associations verify the hypothetical relations between the cost drivers. The output produced is more precise values of the cost drivers that are included in an ABC model and were difficult to estimate. More accurate cost estimate means better pricing decisions for the restaurant managers.Originality/valueThe proposed methodology is an innovative technique that provides more accurate accounting information in the restaurant industry.
Modeling a causality network for tourism development: an empirical analysis
Authors: Assaker Guy , Esposito Vinzi Vincenzo , O'Connor Peter 
Published: November 2011

PurposeThe purpose of this paper is to capture the causal relationships between the primary constituents of the tourism destination paradigm – namely, the economy, society, and the natural and infrastructural environments – and demand for tourism at that destination.Design/methodology/approachInspired by prior tourism literature, the study uses structural equation modeling (SEM) methodologies with a cross‐sectional data sample from 162 countries, to evaluate a priori proposed measurement and structural models for relationships among the economy, society, environment constructs, and tourism.FindingsThe results indicate that although the economy construct was found to have no direct influence on tourism, it does have a mediating, positive impact on tourism through the society and environment constructs, with the society construct paralleling the condition of the infrastructure. Moreover, society and environment were found to have a direct, positive impact on generating tourism activities, and revenues.Research limitations/implicationsThis study contributes to the literature on tourism demand modeling by verifying causal relationships between tourism constructs and supply variables at the “country” level. In other words, it examines whether relationships among tourism constructs and variables exist and, as such, asks if they are responsible for a destination's success.Practical implicationsThis study's results provide destination managers with information to help them understand how individual variables affect the economy, society, and tourism industry aggregately, and as such what actions or investments can help to develop a country's tourism industry effectively.Originality/valueBy integrating several supply‐side factors related to the destination, this paper provides more comprehensive results compared to previous applications of SEM that used a limited number of destination variables and subsequently provided only limited results.
Virtual agents in e‐commerce: representational characteristics for seniors
Authors: Chattaraman Veena , Kwon Wi‐Suk , Gilbert Juan E. , In Shim Soo 
Published: November 2011

PurposeThe purpose of this paper is two‐fold: to investigate virtual agent representational characteristics (modality, interaction style, animation, realism, embodiment, and gender) employed by agent software providers in developing commercial and non‐commercial web sites; and to examine older consumers' preferences in these agent characteristics.Design/methodology/approachStudy 1 involves a content analysis of 64 sample web sites of agent providers, and study 2 consists of four focus group interviews conducted with 25 older consumers in the age group of 65‐82 years.FindingsFindings from both studies reveal some important disconnects between agent characteristics (modality, realism, animation, and gender) offered by virtual agent software providers and those preferred by older consumers. As a result, important recommendations are provided for the development of virtual agents for e‐commerce applications to enhance accessibility for older users.Originality/valueNo previous studies have investigated which agent characteristics enhance web accessibility and are most preferred by older users in the context of e‐commerce applications.
Locating women board members in gendered director networks
Authors: Hawarden Rosanne Jane , Marsland Stephen 
Published: November 2011

PurposeDespite the extensive study of director interlocks very little is known about gendered director networks. Boards of directors are primarily male; globally, only 5‐20 per cent of directors are women and change is described as glacially slow. The extent to which women directors are central to the network, or pushed to the margins, is unknown. Using the tools of social network analysis we extract the components of three director networks, a global and two national networks and locate the women directors. The paper aims to examine the persistence of director networks over time to determine whether gender related differences – apart from size – contribute to the apparent resistance to change.Design/methodology/approachThe paper uses a longitudinal approach, comparing director networks on a global network scale (2004 and 2007FortuneGlobal 200) and a national one (2004 and 2007 New Zealand Stock Exchange) with the iconic 1999FortuneUS 1000 dataset. After extracting the largest connected component, the female directors are separated out. From the 2004 and 2007 data director turnover is calculated to determine the stability of the networks.FindingsFemale directors are more likely to be found in the largest connected component of the mixed gender network, indicating that they are not marginalised. Despite high turnover rates, director networks are stable over time which may manifest as resistance to change.Originality/valueThe structure of gendered director networks is unknown and the location of women directors in the network components has not been considered in board diversity research. The results point to an underlying gender equity in all director networks. A new theoretical approach, glass network theory, has implications for boardroom diversity interventions.
Feminist attributes and entrepreneurial identity
Authors: Orser Barbara J. , Elliott Catherine , Leck Joanne 
Published: November 2011

PurposeThe purpose of this study is to examine how feminist attributes are expressed within entrepreneurial identity.Design/methodology/approachThe study employed a purposive sampling technique to recruit 15 self‐identified “feminist entrepreneurs”. This included retailers, manufacturers, exploration operators, consultants, and professionals. Qualitative data were subject to content analysis.FindingsContrary to a feminine archetype portrayed as caring and nurturing, respondents do not describe themselves as typically portrayed in the feminist literature. Prevalent themes included participative leadership, action‐oriented, and creative thinker/or problem solver.Research limitations/implicationsResearchers should use caution in assuming feminist discourse has direct application to characterizing or stereotyping “feminist” entrepreneurs. The applicability and reliability of “off the shelf” psychometrics to describe contemporary gender roles across the myriads of processes associated with venture creation must also be questioned. Limitations: the purposive and small‐sample limits the generalizability of findings to the diverse community of female entrepreneurs. Testing of the applicability, validity, and reliability of the nomenclature used to describe self‐identity is warranted across international samples of feminist entrepreneurs.Practical implicationsThe current study provides an inventory of feminist entrepreneurs' self‐described leadership attributes. The nomenclature can be used by women‐focused trainers to help clients to recognize their entrepreneurial attributes.Social implicationsThe study may assist women in recognizing identity synergies and conflicts (e.g. within themselves and among family, employees, clients, etc.).Originality/valueThis is the first study that documents feminist entrepreneurs' leadership attributes. As such, the work is a step in seeking to reconcile feminist theory and entrepreneurial practice.
Migrant women in Austria: difficulties with access to health care services
Authors: Habersack Marion , Gerlich Irmina‐Anna , Mandl Manuela 
Published: November 2011

PurposeThe objectives of the study, which focuses on reproductive health care services, are to identify factors that impede adequate access to care for migrant women and to identify possible solutions.Design/methodology/approachIn this case study, problem‐based, semi‐structured individual interviews were conducted with 12 migrant women, eight staff members of non‐governmental organizations (NGOs), and eight staff members of a public hospital (physicians, nurses). The transcripts were analyzed using a grounded thematic approach.FindingsProblems in access to services were identified in four areas: accessibility/information; institutional infrastructure; language barriers; and cultural competences.Social implicationsThere is a need to develop culture‐specific understanding of health amongst service providers working in public hospitals. It is also necessary to raise awareness of traditional beliefs and behavior of migrant women to maximize good quality care. A closer collaboration of hospitals and NGOs is recommended, not least in order to ensure the demand‐ and needs‐orientation, appropriateness, effectiveness, and efficiency of health care for migrant women. Migrant women mentioned different approaches to delivering care – these solutions should, where possible, be applied in practice.Originality/valueThe study correlates and supports knowledge from existing literature regarding possible barriers to the use of health care services by women with migrant backgrounds. Recommendations for overcoming existing barriers are also identified by research participants.
Exploring criminogenic need through victim apology letters II: an IPA analysis of post‐treatment accounts of offending against children
Authors: Duff Simon 
Published: November 2011

PurposeBuilding on previous work, concerned with analysis of pre‐treatment apology letters of men who have offended against children, the current research focuses on post‐treatment apology letters of the same group of men.Design/methodology/approachA total of 26 post‐treatment apology letters of men who attended a community‐based introductory sex offender treatment programme were analysed using interpretative phenomenological analysis (IPA) to explore how the men conceptualise and understand themselves, their behaviour and their victims after treatment.FindingsThe data suggest that the men express themselves in terms of need, however, primarily this is in terms of pro‐social needs, such as a need for forgiveness, rather than in terms of criminogenic need. The one theme identifiable as a criminogenic need is concerned with sexual needs and very little detail is provided that might explain if the need is not otherwise being met; if there is a sexual preference for children, etc. Thus, from these data, it is not possible to identify a specific target need for treatment related to sexual behaviour.Originality/valueThe results raise the question as to whether criminogenic need is the correct level of analysis for thinking about sexual offending and if treatment programmes that use the language of criminogenic need are an appropriate conceptual fit. The identification of pro‐social needs suggests that interventions may need to include work on what Ward and colleagues have referred to as “personal strivings” in order to have a greater impact on victim empathy.

Summary1. Understanding the role of predation in shaping the dynamics of animal communities is a fundamental issue in ecological research. Nevertheless, the complex nature of predator–prey interactions often prevents researchers from modelling them explicitly.2. By using periodic Leslie–Usher matrices and a simulation approach together with parameters obtained from long‐term field projects, we reconstructed the underlying mechanisms of predator–prey demographic interactions and compared the dynamics of the roe deer–red fox–Eurasian lynx–human harvest system with those of the moose–brown bear–gray wolf–human harvest system in the boreal forest ecosystem of the southern Scandinavian Peninsula.3. The functional relationship of both roe deer and moose λ to changes in predation rates from the four predators was remarkably different. Lynx had the strongest impact among the four predators, whereas predation rates by wolves, red foxes, or brown bears generated minor variations in prey population λ. Elasticity values of lynx, wolf, fox and bear predation rates were −0·157, −0·056, −0·031 and −0·006, respectively, but varied with both predator and prey densities.4. Differences in predation impact were only partially related to differences in kill or predation rates, but were rather a result of different distribution of predation events among prey age classes. Therefore, the age composition of killed individuals emerged as the main underlying factor determining the overall per capita impact of predation.5. Our results confirm the complex nature of predator–prey interactions in large terrestrial mammals, by showing that different carnivores preying on the same prey species can exert a dramatically different demographic impact, even in the same ecological context, as a direct consequence of their predation patterns. Similar applications of this analytical framework in other geographical and ecological contexts are needed, but a more general evaluation of the subject is also required, aimed to assess, on a broader systematic and ecological range, what specific traits of a carnivore are most related to its potential impact on prey species.
