Authors: Kim Ok-MI , Park SunIl , Jo Yongjun , Jeong Yongjin
Published: October 2014

In this study, we examined the quality characteristics of oriental melon concentrate according to its content in the production of Makgeolli using uncooked rice. The results show that when more oriental melon concentrate was added to the Makgeolli and as the fermentation progressed, the sugar content of the Makgeolli increased. A slight increase was noted in all samples. The total acidity from the second day of fermentation did not show a significant difference according to the addition of 0.77～0.85% oriental melon concentrate. The pH of Makgeolli was slightly higher. The addition of more oriental melon concentrate after its decrease on the first day showed no significant difference in the pH. Reducing sugars in the Makgeolli slightly increase on the second day, after it rapidly decreased on the first day. The alcohol content increased as the fermentation progressed, and the Makgeolli with 9% (v/w) oriental melon concentrate added on the fourth day of its fermentation showed the highest alcohol content of 11.15%. Thus, it verified that as more oriental melon concentrate is added, the higher the alcohol content becomes. The acetaldehyde content of the alcoholic ingredients was low. The addition of and the increase in the oriental melon concentrate and the methanol were highest in the Makgeolli when 6% (v/w) oriental melon concentrate(199.08 ppm) was added. For the sensory characteristics, the Makgeolli with 6% (v/w) oriental melon concentrate showed the highest color, odor, taste and overall values of 3.60, 3.60, 2.80 and 3.60, respectively; but in general, it showed low values. The result showed that during the production of Makgeolli, oriental melon concentrate can be added, but a study on the use of a sweetener to improve the quality of the Makgeolli is desirable.

Authors: Jun So-Yun , Lee Yeon-Kyung
Published: October 2014

This study was conducted to investigate the effects of various heat treatments on the microbial reduction and germination of red radish seeds for the development of effective and economical sterilization methods of improving microbial safety without reducting the germination rate. Hydrothermal treatment was conducted at 60, 65, 70, 75, 80, and 90℃ for 30 and 60 seconds, and dry heat treatment was performed at 70, 80, 90, and 100℃ for 5 minutes. In the seeds that underwent the hydrothermal treatment, time had little effect on the microbial reduction. There was no significant microbial reduction over time. However, there was significant microbial reduction as temperatures increased (p<0.001). The total plate count (TPC) was reduced by more than 3 logs, and Listeria monocytogenes was not detected at temperatures above 70°C. In the seeds that were subjected to the dry heat treatment, the TPC and the population of the L. monocytogenes were significantly reduced as the temperatures increased (p<0.001). After treatment at 100°C for 5 minutes, the TPC and the L. monocytogenes were reduced by 3 logs. As with the microbial reduction, time had little effect on the germination. There were no significant changes in the germination after the hydrothermal treatment over time; but at the temperatures above 75°C, the germination rate significantly decreased as the temperature increased (p<0.001). When the seeds were soaked after the hydrothermal treatment, their germination was stimulated. The dry heat treatment at temperatures of 80°C and higher significantly decreased the germination rate as the temperature increased (p<0.001). Dry heat treatment before the germination of the seeds soaked in distilled water for three hours significantly decreased the germination at temperatures greater than 90°C (p<0.05). This study showed that appropriate heat treatments can increase the microbiological safety and germination of red radish seeds.

Authors: Bae Hyun-Kyung , Chung Shin-Kyo
Published: October 2014

To investigate the natural antioxidant and antimicrobial phytochemicals from black bamboo (Phyllostachys nigra MUNRO) leaves, the solvent fractions from crude methanol extract were made with n-hexane, ethyl acetate, and butanol, and their antioxidant and antimicrobial activities were determined. The antioxidant activities were examined by 1,1-diphenyl-1-picrylhydrazyl (DPPH) method and ferric ion reducing antioxidant power (FRAP) method, and the antimicrobial activities against Staphylococcus aureus were tested by paper disc agar diffusion method. Total phenolic contents and total flavonoid contents of the solvent fractions were also determined. The ethyl acetate fraction with the highest total phenolic contents among all fractions showed the strong antioxidant activities by DPPH method and FRAP method, and antimicrobial activities against S. aureus at all test concentrations. Caffeic acid, ferulic acid, quercetin, and kaempferol were analyzed by HPLC in the ethyl acetate fraction from black bamboo leaves by the comparison with the standard chemicals. It is supposed that the ethyl acetate fraction from black bamboo leaves could be used as natural preservatives in the food industry.

Authors: Park Hye-Mi , Hong Joo-Heon
Published: October 2014

This study was conducted to examine the antioxidant activities of extracts derived with different extraction methods (HE, hot water extraction; UE, ultrasonic extraction; and PE, pressured extraction) from Phellinuslinteus mycelium in Mori ramulus. The extraction yield of PE (7.73%) was higher than that of UE (6.03%) and of HE (5.44%). The total phenolic and flavonoid contents of PE were 9.87 g/100 g and 1.90 g/100 g, respectively. The oxygen radical absorbance capacity (ORAC) of PE (769.63 μM/g FW) was higher than that of HE (622.96 μM/g FW) and of UE (249.06 μM/g FW). The DPPH and ABTS radical scavenging activities of PE at 1,000 μg/mL were 35.85% and 51.42%, respectively. The superoxide radical scavenging activity of PE, 29.16-93.89%, was higher than that of other extracts. The ferric-reducing antioxidant power and the reducing power of PE were 180.60-607.93 μM and 0.14-0.51, respectively. The tyrosinase inhibition activity of PE (9.66-24.05%) improved with an increase in the treatment concentration. The antioxidant and tyrosinase inhibition activities of PE were significantly higher than those of the other extracts. In conclusion, we provided experimental evidence that Phellinus linteus mycelium extracts from Mori ramulus have potential as functional materials.
Effects of combined acetic acid and UV-C irradiation treatment on the microbial growth and the quality of sedum during its storage
Authors: Seong Ki Hyun , Kang Ji Hoon , Song Kyung Bin
Published: October 2014

With the current consumer trend toward health and wellbeing, the demand for consumption of fresh cut vegetables has been increasing. As a popular vegetable with functional components, sedum (Sedum sarmentosum) is widely used in Korea as a side dish that needs no cooking. In this study, to provide a hurdle technology for postharvest sedum, the effects of combined treatment of 1% acetic acid for washing and 10 kJ/m2 UV-C irradiation on the microbial growth and quality of sedum were examined. After the treatment, the sedum samples were stored at 10℃for six days, and the results of their microbial analysis as well as their color, vitamin C content, and antioxidant activity were analyzed. The combined treatment with acetic acid and UV-C irradiation reduced the initial populations of the total aerobic bacteria and the yeast and molds in the sedum by 3.28 and 4.22 log CFU/g, respectively, compared to those in the control. The Hunter L, a, and b values of the sedum did not significantly differ across the treatments. In addition, the vitamin C content and the antioxidant activity decreased significantly during the storage, regardless of the treatment. These results suggest that the combined treatment with 1% acetic acid and 10 kJ/m2 UV-C irradiation can be useful as a hurdle technology for retaining the microbiological safety and quality of sedum during its storage.
Screening of DPPH radical scavenging and antimicrobial activity of extracts from local some native plants
Authors: Kim Hyun-Soo , Ahn Joung-Jwa , Choi Tae-Ho , Hwang Tae-Young
Published: October 2014

This study was conducted to determine the antioxidant potentials of some available plants to source alternate antioxidants and antibiotics. The antioxidant activity was evaluated by determining the antioxidant activity reducing powers and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities of extracts from some local edible native plants. The DPPH radical scavenging activity of the extracts was found to have been 0.41-94.84%. The Elsholtziasplendens NAKAI extract (85ºC, ethanol, accelerated solvent extraction) showed the highest level of antioxidant activity. Eight samples of plant extracts were evaluated for their antimicrobial activities against three microflora (Bacillus subtilis, Escherichia coli, and Candida albicans) using disc diffusion assay. Two samples (Geranium krameri FR. Et SAV. and Cleyera japonica Thunb.) had much more intensive antimicrobial activities than the control. However, their DPPH free radical scavenging activity levels were only 14.50 and 13.85, respectively. It is suggested that they could be used as natural preservatives against bacterial contamination in cosmetics and foods, in place of the common synthetic preservatives currently used.
Long-term potentiation can be induced in the CA1 region of hippocampus in the absence of αCaMKII T286-autophosphorylation
Authors: Villers Agnès , Giese Karl Peter , Ris Laurence
Published: October 2014

α-calcium/calmodulin-dependent protein kinase (αCaMKII) T286-autophosphorylation provides a short-term molecular memory that was thought to be required for LTP and for learning and memory. However, it has been shown that learning can occur in αCaMKII-T286A mutant mice after a massed training protocol. This raises the question of whether there might be a form of LTP in these mice that can occur without T286 autophosphorylation. In this study, we confirmed that in CA1 pyramidal cells, LTP induced in acute hippocampal slices, after a recovery period in an interface chamber, is strictly dependent on postsynaptic αCaMKII autophosphorylation. However, we demonstrated that αCaMKII-autophosphorylation-independent plasticity can occur in the hippocampus but at the expense of synaptic specificity. This nonspecific LTP was observed in mutant and wild-type mice after a recovery period in a submersion chamber and was independent of NMDA receptors. Moreover, when slices prepared from mutant mice were preincubated during 2 h with rapamycin, high-frequency trains induced a synapse-specific LTP which was added to the nonspecific LTP. This specific LTP was related to an increase in the duration and the amplitude of NMDA receptor-mediated response induced by rapamycin.

The political trajectory of the Brazilian CSR movement
Authors: Milcíades Peña Alejandro
Published: October 2014

Purpose

– This paper aims to examine the origins and trajectory of the Brazilian corporate social responsibility (CSR) movement in relation to political economic developments in Brazil during and prior to the 2000s.

Design/methodology/approach

– This paper relies on a historical political account that traces the evolution of the main actors in the CSR movement since the democratization period, details the contacts established with relevant political and civil society groups and outlines the adaptation of their agenda to the changing context.

Findings

– The long association between a faction of Brazilian business and the Workers’ Party (PT) and the overlapping state – society relations characteristic of the Brazilian political economy explain the domestic and international standing of the Brazilian CSR movement, in particular since 2003 when Lula da Silva came to power.

Originality/value

– The trajectory of Brazilian CSR and participation in related global initiatives cannot be explained through market-based or isomorphic approaches traditionally used to analyze the diffusion of governance mechanisms in the Global South. Rather, it highlights the relevance of local political structures in shaping involvement in global governance initiatives.
The transformation of state-business relations in an emerging economy
Authors: Hopewell Kristen
Published: October 2014

Purpose

– The aim of this paper is to revisit the Brazilian case in an effort to shed light on how state-business relations have been transformed in the contemporary era of globalization. Brazil has long been considered the archetype of “dependent development”, having served as the inspiration for the classic theory of the relationship between states and capital in the semi-peripheral states of the developing world. Since the theory of dependent development was initially formulated in the 1970s, however, both the Brazilian political economy and the global context in which it is situated have changed dramatically.

Design/methodology/approach

– The analysis draws on 15 months of field research conducted in Sao Paulo, Brasilia, Beijing, New Delhi and Washington, as well as at the World Trade Organization (WTO) in Geneva, involving 157 interviews with senior government officials, trade negotiators and representatives of industry and non-governmental organizations, ethnographic observation and extensive documentary research.

Findings

– The author shows how the emergence of a highly competitive export-oriented agribusiness sector in Brazil has prompted the expansion and internationalization of domestic capital, leading to the emergence of an independent, private sector lobby with considerable influence on the Brazilian state. Driven by the rise of Brazilian agribusiness, the state and capital have allied together to aggressively pursue the expansion of markets for Brazilian exports, specifically through dispute settlement and negotiations at the WTO.

Originality/value

– These findings challenge conventional understandings of state-business relations in emerging economies such as Brazil.
The Brazilian sub-imperialist strategy of regional insertion
Authors: Ceci Misoczky Maria , Imasato Takeyoshi
Published: October 2014

Purpose

– The purpose of this paper is to analyze the Brazilian strategy of regional insertion with the support of the Marxist Theory of Dependency (MTD), represented by the work of Ruy Mauro Marini because it allows for the consideration of relations of power within the national scenario and policies resulting from class alliances embedded in the domestic structure of dependency.

Design/methodology/approach

– The paper discusses the main positions concerning the Varieties of Capitalism approach, arguing that the MTD and specifically Marini’s work can contribute to overcoming some of its limits. These arguments are illustrated through the analysis of the Brazilian strategy of regional competitive insertion focusing on the IIRSA project and the Brazilian Multinational Companies directly involved.

Findings

– The concept of sub-imperialism has helped to understand the logic behind the Brazilian strategy of regional insertion as part of a historical trajectory that includes the re-edition of a political drive for being the regional leader; the privilege of class fractions benefiting from the access to public funds and new markets (necessary to guarantee their continued and increased profitability); the reinforcement of regional inequalities and, at the same time, the reproduction of Brazilian dependency.

Originality/value

– A renewed MTD can contribute to understanding the specific politico-economic strategies of peripheral countries. It can also overcome the limits of the Varieties of Capitalism approach by articulating the economic and political dimensions; by avoiding the structural – functionalist constrains of the institutional perspective; and by allowing the consideration of marginalized voices, rather than considering only the institutionalized ones.

Authors: He Wu , Watson Silvana
Published: October 2014

Purpose

– To improve the quality of field experience, support field experience cooperation and streamline field experience management, the purpose of this paper is to describe the experience in using Activity Theory to design and develop a web-based field experience tracking system for a special education program.

Design/methodology/approach

– The authors used Activity Theory to design and develop a web-based field experience tracking system for a special education program. An in-depth evaluation of the developed web-based system including usability testing and actual use of the system was conducted.

Findings

– The evaluation and data analysis results demonstrate the value of Activity Theory and show that a web-based tracking system is a valuable tool to support the management of pre-service teachers’ field experiences.

Originality/value

– This is the first paper to discuss the design and development of field experience tracking system using Activity Theory. This paper can be used to motivate other developers to use Activity theory to design campus-wide information system. The system and methodology the authors used in this project has wider applicability and generalizability, and can be applied to the management of other competency and field based professional training in areas such as nursing, social work and medicine.
Emotions and visitors’ satisfaction at a museum
Authors: Del Chiappa Giacomo , Andreu Luisa , G. Gallarza Martina
Published: October 2014

Purpose

– This research aims to investigate whether emotions can be considered as a suitable variable to segment visitors at a museum. Furthermore, it seeks to analyse whether emotions influence visitor satisfaction and whether this depends on objective variables (such as age, gender and level of education) or not.

Design/methodology/approach

– A structured questionnaire was developed and data were collected at the National Museum of Archaeology “G.A. Sanna” in Sardinia (Italy) via 410 face-to-face interviews. Hierarchical and non-hierarchical cluster analyses and a series of chi-squared tests were run for the purpose of the study.

Findings

– Two segments were identified. The cluster with the higher positive emotions reported perceiving a higher level of attractiveness and uniqueness at the museum, and of being more satisfied than the other group. Furthermore, no significant differences were reported between the two segments based on socio-demographic characteristics.

Research limitations/implications

– The study is site-specific. The application of the study to other museums would allow for wider generalisations to be made from the results obtained.

Practical implications

– Managers should market and position museums as an emotionally driven experience consumption site. Furthermore, they should consider both cognitive and emotional aspects of visitor experience when designing and planning their businesses, as well as when assessing the visitor’s satisfaction.

Originality/value

– This study adds to the growing literature on emotions as a tool for segmentation and positioning, and suggests that cognitive and emotional aspects should be considered simultaneously when measuring visitors’ satisfaction. Further, it suggests that emotions are more significant than cognitive aspects in shaping visitors’ satisfaction.
Creative tourism: a preliminary examination of creative tourists’ motivation, experience, perceived value and revisit intention
Authors: Chang Lan-Lan , F. Backman Kenneth , Chih Huang Yu
Published: October 2014

Purpose

– The purpose of this study is to investigate the relationships between tourists’ motivation, experience, perceived value and revisit intentions to creative tourism destinations. The ever-growing concept of creativity has been introduced into the tourism field. Creative tourism has been viewed as a strategy to regenerate destinations physically, culturally and socially. To develop tourism products and provide services that integrate the concept of creativity to satisfy tourists’ needs by developing a more active and long-lasting form of experience, this study aims to examine tourist consumption psychology in the context of creative tourism destinations. Past studies have identified motivation, perceived value and experience as three major antecedents affecting tourists’ revisit intentions.

Design/methodology/approach

– The empirical study was carried out in three popular creative tourism spots, Meinong, Shuili and Yingge, located, respectively, in the north, middle and south Taiwan. These creative tourism sites provide pottery, crafts, arts, workshops and other creative activities that integrate authentic local culture to engage tourists with fulfilling and meaningful experiences. The on-site survey was conducted on both weekdays and weekends during March 2012. Self-administrated questionnaires were distributed to participants who were systematically selected at the main gate of the study areas. In total, 417 questionnaires were collected.

Findings

– The results indicated that on-site tourism experience was the most influential antecedent of revisit intention to creative tourism sites in terms of the magnitude of the standardized coefficient. The unique variances of motivation factors and perceived value were too small to be statistically significant to explain revisit intentions. The present study contributes to the ever-increasing tendency for creative industries in Taiwan to develop creative tourism products and services that encompass authentic local culture and art in enhancing tourist experience.

Originality/value

– For business operators, this study suggests that if owners of creative destinations would like to attract repeat tourists, the tourists’ experiences are surely critical in developing service blueprints to meet the needs and wants of customers; they should pay more attention to understanding what tourists experience when they visit creative tourism attractions.
Distinctive features of service performance measurement
Authors: Jääskeläinen Aki , Laihonen Harri , Lönnqvist Antti
Published: October 2014

Purpose

– The purpose of this paper is to study the distinctive features of service performance measurement. It also provides an overview of current status of performance measurement in three service sectors in Finland.

Design/methodology/approach

– The paper builds on two complementary empirical studies. In the first study, data were gathered through individual interviews in Finnish service organizations. In the second study, group interviews were held in order to enhance the understanding. The service sectors studied are knowledge-intensive, public and industrial services. There are two main units of analysis in the data set: an organization and service operations.

Findings

– The results show that the specific performance measurement characteristics are more apparent at service operations level. The findings reveal three distinctive features of service performance measurement. First, the contingency perspective stresses a need to consider the characteristics of different service contexts. Second, customer-orientation implies that the measurement should also cover customers’ actions during the service operation as well as the impacts of service operations. Third, the systemic perspective proposes that performance measurement should encompass all actors participating to service operations.

Research limitations/implications

– The results provide support for structuring the existing research and identifying paths for future research. They also assist practitioners in their search for best measurement practices.

Originality/value

– This paper contributes by providing empirical insights from three service sectors on the development needs of performance measurement. The findings provide understanding on what exactly makes service performance measurement problematic and suggests three paths to move forward.

Authors: Magazzino Cosimo , Michela Mantovani
Published: October 2014

Purpose

– The purpose of this paper is to examine the counterfeiting process in Italy, at a subnational level.

Design/methodology/approach

– The paper uses panel data estimators and mixture models regression.

Findings

– The paper finds that homogeneous clusters of regions could be derived, as a result of economic and geographical reasons. Moreover, household and public administration expenditure, indirect taxation, foreigners/population ratio and the number of ports have a positive impact on the counterfeiting diffusion index.

Practical implications

– The paper is practical as a source of reference in contrasting counterfeiting process.

Originality/value

– The paper uses new data applying recent econometric techniques to find homogeneous groups of regions on counterfeiting index.
An integrative model in predicting corporate tax fraud
Authors: Azrina Mohd Yusof Nor , Ling Lai Ming
Published: October 2014

Purpose

– This paper aims to present an integrative model in predicting corporate tax fraud.

Design/methodology/approach

– This paper is grounded on three theories, namely, the theory of reasoned action, theory of planned behaviour and the “Fraud Diamond Theory”.

Findings

– By integrating these three theories, this paper proposes that individual cognitive factors, fraud diamond factors and organizational factors such as normative and control factors influence managers to commit corporate tax fraud.

Practical implications

– Practically, the proposed integrative model enables the government and tax authority to understand on why corporate managers engage in corporate tax fraud. It will also allow them to devise practical methods and strategies to prevent the corporate managers to engage in tax fraud.

Originality/value

– This study has merit that proposed an integrative model in predicting corporate tax fraud. Research on corporate tax fraud has been the subject of limited investigation; hence, this study contributes to the tax compliance literature by proposing an integrative model to study corporate tax fraud in a Malaysian tax setting. Future studies can be conducted to test the proposed integrative model in examining the circumstances of managers’ intention to commit corporate tax fraud.
How do R&D employees use their social networks to acquire user information?
Authors: Wadell Carl , Björk Jennie , Magnusson Mats
Published: October 2014

Purpose

– This article aims to investigate how R&D employees use their social networks to acquire user information and how this information is used in the development of new products.

Design/methodology/approach

– A single case study was conducted within a business unit at a multinational medical technology company. Data were collected through a mixed method.

Findings

– The results show that many R&D employees lack social networks through which they can acquire information about the users’ needs. However, some R&D employees establish cost-efficient relationships to people with a direct experience of using the company’s products. These relationships are established over time and are often used in a rather informal way to acquire user information. Moreover, the results show how R&D employees are purposefully complementing these relationships with more occasional interactions with people who hold direct and indirect use experiences.

Research limitations/implications

– As with most single-case studies, it will be important to replicate this investigation in other contexts to clarify the generalizability of the findings.

Practical implications

– The article shows how important it is that management provides R&D employees with opportunities to establish, nurture and utilize relationships conducive to information about the users’ needs. The article provides some advice on how this can be accomplished.

Originality/value

– This is one of the first articles that clearly explain how R&D employees use their social networks to acquire user information for the development of new products.
Creating technological knowledge in vintage communities of practice
Authors: Schiavone Francesco , Borzillo Stefano
Published: October 2014

Purpose

– The purpose of this paper is to show how members of a “vintage community of practice” (CoP) – the Multiple Arcade Machine Emulator (MAME) community – recombine old technological knowledge with new technological knowledge. A vintage CoP is a group of aficionados of old technology who keep using it even after superior new technologies have emerged and technological change has taken place. This paper presents mechanisms through which developers and gamers in the MAME community and its subcommunities or hubs select and recombine old and new technology to update old arcade videogames in a format that is playable on current personal computers (PCs).

Design/methodological approach

– An inductive single-case exploratory case study was conducted in the MAME community. Semi-structured interviews were conducted with core community members to uncover mechanisms through which old technology-related knowledge (T-RK) was combined with new T-RK to update old versions of arcade video games into software versions that can be played on current PCs. Informant discourses were analyzed using first- and second-order coding methods.

Findings

– Our data revealed three mechanisms through which community leaders positively impact new and old T-RK recombinations that led to new knowledge creation within the MAME vintage CoP. We named these mechanismsleader mentorship,leader self-development propensityandclustering in the community. Our data also revealed a two-phase knowledge creation process in an open-source software community (OSSC) that supports the MAME community: knowledge selection and knowledge recombination.

Research limitations/implications

– The study is limited by the size of the investigated community, so further research should be conducted in multiple vintage CoPs so as to generalize our results.

Practical implications

– Our results offer practitioners insights into the internal knowledge creation mechanisms that occur in vintage CoPs. Our findings seek to motivate managers to start collaborating with vintage CoPs to develop products for the niche vintage product markets.

Originality/value

– This research is one of the first in the field of vintage communities of practice. It affords understanding of social mechanisms by which old technologies are combined with new ones to give rise to vintage products that suit the needs of niche vintage product markets.
What matters for knowledge sharing in collectivistic cultures? Empirical evidence from China
Authors: Ma Zhenzhong , Huang Yufang , Wu Jie , Dong Weiwei , Qi Liyun
Published: October 2014

Purpose

– The purpose of this study is to identify key factors that facilitate knowledge sharing in collectivistic cultures and further help better understand knowledge management in the international context.

Design/methodology/approach

– Using a survey method, this study collected data from over 200 managerial employees in knowledge management-based project teams from China. Regression analysis was then conducted to analyze the impact of individual differences and environmental factors on the willingness to share knowledge among team members to identify key factors for successful knowledge retention in the constantly changing organizational environment in a collectivistic context.

Findings

– The results show that incentives are very important in individual’s decision to share knowledge in project teams even in a collectivistic culture like China and both intrinsically and extrinsically motivated individuals tend to share more knowledge with their team members. Individuals with high altruism are also found more likely to share knowledge with others. Moreover, a trusting environment and explicit knowledge will facilitate knowledge sharing for better retention.

Research limitations/implications

– More studies should be conducted in other collectivistic cultures to explore cultural barriers in knowledge management in the international context and comparative studies using samples from different cultural backgrounds are also encouraged to help extend the theories on knowledge management.

Originality/value

– While it is well-known that knowledge sharing is essential for organization to maintain competitive advantage, relatively few studies have examined knowledge sharing in collectivistic cultures, and even fewer have done so in China.

Interorganisational partnerships and knowledge sharing: the perspective of non-profit organisations (NPOs)
Authors: Rathi Dinesh , M. Given Lisa , Forcier Eric
Published: October 2014

Purpose

– This paper aims first to identify key interorganisational partnership types among non-profit organisations (NPOs) and second to determine how knowledge sharing takes place within each type of partnership. Results explore the value of social media specifically in facilitating external relationships between NPOs, firms and the communities they serve.

Design/methodology/approach

– Empirical qualitative analysis of exploratory interviews with 16 Canadian NPOs generates a non-exhaustive classification of partnership types emerging from these organisations, and their defining characteristics in the context of interorganisational knowledge sharing.

Findings

– Overall eight categories of partnerships from the sampled NPOs emerged from the analysis of the data. These include business partnerships, sector partnerships, community partnerships, government partnerships, expert partnerships, endorsement partnerships, charter partnerships and hybrid partnerships. Using examples from interviews, the sharing of knowledge within each of these partnerships is defined uniquely in terms of directionality (i.e. uni-directional, bi-directional, multi-directional knowledge sharing) and formality (i.e. informal, semi-formal or formal knowledge sharing).Specific practices within these relationships also arise from examples, in particular, the use of social media to support informal and community-driven collaborations. Twitter, as a popular social networking tool, emerges as a preferred medium that supports interorganisational partnerships relevant to NPOs.

Originality/value

– This research is valuable in identifying the knowledge management practices unique to NPOs. By examining and discussing specific examples of partnerships encountered among NPOs, this paper contributes original findings about the implications of interorganisational knowledge sharing, as well as the impact of emerging social technologies on same.
Moving social marketing beyond personal change to social change
Authors: P.D. Guidry Jeanine , D. Waters Richard , D. Saxton Gregory
Published: October 2014

Purpose

– This paper aims to examine what type of messaging on Twitter is most effective for helping move social marketing beyond focusing on personal changes to find out what messages help turn members of the public into vocal advocates for these organizations’ social changes. Social marketing scholarship has regularly focused on how organizations can effectively influence changes in awareness and behaviors among their targeted audience. Communication scholarship, however, has repeatedly shown that the most influential form of persuasion happens interpersonally. As such, it is imperative that organizations learn how to engage audiences and facilitate the discussion about organizational messages between individuals. Social media provide platforms for such conversations, as organizational messaging can be shared and discussed by individuals with others in their networks.

Design/methodology/approach

– Through a content analysis of 3,415 Twitter updates from 50 nonprofit organizations, this study identifies specific types of messages that are more likely to get stakeholders retweeting, archiving and discussing the organizations’ messaging through regression analysis.

Findings

– Messages focusing on calls-to-action and community building generated the most retweets and Twitter conversation; however, they were also the least used strategies by nonprofit organizations.

Originality/value

– Research has regularly examined the types of messages sent out by nonprofit organizations on Twitter, but they have not tested those messages against measures of engagement. This study pushes the understanding of social media communication to the next level by analyzing those message categories against metrics provided by Twitter for each tweet in the sample.
The benefits of belongingness and interactional fairness to interpersonal citizenship behavior
Authors: Kyei-Poku Ivy
Published: October 2014

Purpose

– The purpose of this paper is to examine the main and indirect effects of belongingness and interactional fairness on interpersonal citizenship behavior.

Design/methodology/approach

– Field data were obtained from 141 subordinate-supervisor dyads from diverse occupations and organizations within Canada. The study was cross-sectional in nature.

Findings

– Consistent with expectations the findings demonstrates that interactional fairness positively predicts employee sense of belongingness, and employees show more helping behavior (supervisor rated) when they have a stronger sense of belongingness at work. Belongingness partially mediates the relationship between interactional fairness and interpersonal behavior.

Research limitations/implications

– Future research could involve investigating a broader range of mediating mechanisms that might promote interpersonal citizenship behavior; for example, trust. As previously indicated, belongingness partially mediates the relationship between interactional fairness and interpersonal citizenship behavior, implying other possible mechanisms through which interactional fairness influences follower behaviors. Moreover, this research can be extended to include to other forms of prosocial behaviors (e.g. innovative behavior).

Practical implications

– Satisfying employees’ need for belonging is an important aspect of organizational life and useful in promoting helping behaviors among coworkers, it is essential for organizations to, therefore, create a work culture of inclusiveness. It is prudent for organizations to also expend greater effort to maximize interactional fairness by introducing programs intended for training organizational leaders how to be fair.

Originality/value

– Interpersonal citizenship behavior is important for group and organizational functioning; however, current psychological models are insufficient for understanding these behaviors. To advance the understanding, this study attempts to directly test individuals’ sense of belongingness as the psychological mechanism through which interactional justice can influence interpersonal citizenship behavior.
Examining the influence of transformational leadership, organizational commitment, job embeddedness, and job search behaviors on turnover intentions in intercollegiate athletics
Authors: Welty Peachey Jon , J. Burton Laura , E. Wells Janelle
Published: October 2014

Purpose

– The purpose of this paper is to explore the influence of transformational leadership, organizational commitment, job embeddedness, and job search behaviors on voluntary turnover intentions among senior administrators in intercollegiate athletics departments in the USA.

Design/methodology/approach

– In total, 196 senior athletic administrators completed an online questionnaire assessing transformational leadership of the athletic director, organizational commitment, job embeddedness, job search behaviors, and voluntary turnover intentions. A model of turnover intentions was tested using structural equation modeling.

Findings

– Results indicated that organizational commitment did not mediate the relationship between transformational leadership and job search behaviors, nor did job search behaviors mediate the relationship between organizational commitment and turnover intentions. However, job embeddedness moderated the relationship between organizational commitment and job search behaviors.

Research limitations/implications

– While the study results cannot be generalized outside of the intercollegiate context, the findings further the understanding of variables influencing the relationship between transformational leadership and turnover, which can guide future research.

Practical implications

– To limit job search and retain employees, managers would benefit from targeting retention efforts on employees with less organizational commitment and lower levels of job embededdness. Managers should strive to foster job embeddedness among employees.

Originality/value

– This study examines potential mediating and moderating variables of the relationship between transformational leadership and voluntary turnover intentions, an area of inquiry that has not been fully explored in the literature.
Audit quality of outsourced information technology controls
Authors: Mazza Tatiana , Azzali Stefano , Fornaciari Luca
Published: October 2014

Purpose

– This paper aims to test the positive relationship between audit quality (AQ) of outsourced information technology controls (ITC) and information technology audit quality (ITAQ).

Design/methodology/approach

– Factor analysis, ordinary least squares (OLS) regressions and simulations.

Findings

– Scoping and planning phases of the audit cycle account for about 69 per cent of ITAQ. The AQ of outsourced ITC is strongly and directly related to ITAQ. Improvement of AQ of outsourced ITC may be achieved through evaluation of control design and operating effectiveness by service auditor as well as direct evaluation by the client in service provider location.

Research limitations/implications

– Sample size and input items in factor analysis.

Practical implications

– Companies and auditors could improve ITAQ through a better organization of the scoping and planning activities; they could also improve the AQ of outsourced ITC using direct evaluation in the service provider location supplemented with service auditor reports. Regulators could refine or change laws and frameworks to take into account the factors of ITAQ and the methodology of evaluation of outsourced ITC.

Originality/value

– Private data collected by questionnaire. The measures of ITAQ and the OLS model could be tested in future research, in countries with different frameworks and regulations related to AQ, different weight of outsourced information technology and other characteristics related to clients, service providers and service auditors.
