Quality improvement of manuka honey through the application of high pressure processing

The quality of honey is known to be compromised when it goes through thermal processing due to its negative impact on the unstable and thermolabile honey components which originated from the nectar and bees themselves. This present work is undertaken to access the use of an emerging food preservation technique known as “High Pressure Processing” for treating honey, as an alternative to the conventional thermal processing. In this thesis, honey quality has been addressed by measuring the effects of high pressure processing parameters (pressure, time and temperature) on nutritional properties of honey, namely total phenolic content and antioxidant activity. Honey samples, contained in small pouches, were subjected to different pressures (200-600 MPa) at close to ambient temperatures (25-33°C) for different holding times (10 to 30 min). Thermal processing (49- 70°C) was also carried out for comparison purpose. Results demonstrated that high pressure processing operated at 600 MPa for 10 min has capability to increase significantly the total phenolic content and antioxidant activity by 47% and 30%, respectively. Besides, the result showed that high pressure processing can maintain the natural colour of honey which relates directly to consumer perception, while retaining its shear-thinning behaviour and viscosity with no significant changes (p > 0.05). High pressure processing can also control hydroxymethylfurfural (HMF) concentration in honey during process within the standard limit, 16.93 to 18.76 mg/kg (which is below than the maximum allowed limit of 40 mg/kg). This work also reveals that high pressure processing can enhance antibacterial activity of Manuka honey significantly. It shows an increase in the percentage inhibition of Staphylococcus epidermidis from 64.15 ± 5.86% to 84.34 ± 7.62% when honey was subjected to 600 MPa. Storage studies for one year at room temperature (25°C) demonstrated that high pressure-treated samples have a good retention to the physicochemical, nutritional and rheological properties of honey throughout storage, which confirms that the positive effect of high pressure on honey is not a temporary effect. Whereas, an insight study on the safety part showed that the Saccharomyces cerevisiae cell varied linearly with ° Brix, indicating that food compressibility has a significant role in the microbial inactivation

eEnabled internet distribution for small and medium sized hotels: the case of hospitality SMEs in Athens

Advances in information and communications technologies (ICTs) have strategic implications for a wide range of industries. Tourism and hospitality have dramatically changed by the ICTs and the Internet and gradually emerge as the leading industry on online expenditure. The Internet revolutionised traditional distribution models, enabled new entries propelled both disintermediation and reintermediation and altered the sources of competitive advantage. This paper explores the strategic implications of ICTs and the perceived advantages and disadvantages of Internet distribution for small and medium-sized hospitality enterprises (SMEs). Primary research in Athens hotels demonstrates the effects of the Internet and ICTs for secondary markets, where there is lower penetration and ICT adoption. Interviews and questionnaires identified a number of strategies in order to optimise distribution. The analysis illustrates the strategic role of ICTs and the Internet for hospitality organisations and Small and Medium-sized organisations in general. Most hotels employ a distribution mix that determines the level and employment of the Internet. The paper demonstrates that only organisations that use ICTs strategically will be able to develop their electronic distribution and achieve competitive advantages in the future

The Relevance of Digital Sharing Business Models for Sustainability

There is a growing discussion about the "Digital Sharing Economy" (DSE). The pervasiveness of digital platforms and the growing interest in a sharing (rather than ownership) style of consumption have allowed for sharing practices to scale up and become a widespread phenomenon. Digital sharing platforms offer a wide variety of services which appear to be more affordable, efficient, and accessible than their conventional counterparts, making them more attractive in the eyes of consumers. The DSE has manifested itself most remarkably in consumer-to-consumer (C2C) and business-to-consumer (B2C) sharing models. New business models have been created to capture and offer the values driving the emerging sharing trend. The innovative, digitally enabled mode of providing access to resources as a service in the DSE has changed consumption patterns both at micro level, as a change in individual lifestyles, and at macro level, manifested in a transformation of socio-economic structures. These ongoing changes may have both positive and negative implications for society from a sustainability perspective. Recognising that the (potential and actual) impacts of sharing platforms on sustainability have not been studied in a systematic way yet, the present paper aims to develop a systematic insight into this interaction by focusing on the business models emerging around sharing platforms as a central starting point. To achieve this, we use a typology of business models that recognizes the affordances and key attributes of sharing in the DSE. The typology covers both C2C and B2C models of sharing. Based on this typology, we discuss the implications of each type of sharing model for sustainability by asking two central questions: How may the given type of sharing affect resource consumption? And what will be the potential impacts on social practices and structures? We hope that the present study can serve as a guideline for assessing the sustainability impacts of sharing platforms -- either already operating in the market or envisaged. By highlighting the aspects most relevant from a sustainability point of view, we expect to contribute to an evolution of the DSE business models towards sustainable development

Straussian Grounded-Theory Method: An Illustration

This paper demonstrates the benefits and application of Straussian Grounded Theory method in conducting research in complex settings where parameters are poorly defined. It provides a detailed illustration on how this method can be used to build an internationalization theory. To be specific, this paper exposes readers to the behind-the-scene work to develop a theory on the internationalization of small and medium-sized enterprises based in transition economies. It describes each step from sampling to coding and then to theory formation, explaining the rationale each step of the way. The readers can therefore see how a theory took shape and develop from raw data to refined theoretical propositions/hypotheses

A Review on various E-business and M-business models & Research Opportunities

A business model is a set of process/activities that results in sustainable profit through desired revenue and customer value. The business model spells out how a company makes money by specifying its position in the value chain. A business model which uses electronic communication technology such as internet for exchanging information is called e-business model. The e-business model includes the roles and relationships among a firm's customers, allies, and suppliers; the major flows of product, services, information, and money; and the major benefits to the participants. This paper contains review on various business models used in e-business, m-business, and m banking. All the major E-commerce business models which fall under 3 main categories : B2B - Business to business, B2C - Business to consumer, C2C - Consumer to consumer are also discussed with their benefits and limitations. Based on business model framework, various research agenda and opportunities are identified and elaborated

Mining social network data for personalisation and privacy concerns: A case study of Facebook’s Beacon

This is the post-print version of the final published paper that is available from the link below.The popular success of online social networking sites (SNS) such as Facebook is a hugely tempting resource of data mining for businesses engaged in personalised marketing. The use of personal information, willingly shared between online friends' networks intuitively appears to be a natural extension of current advertising strategies such as word-of-mouth and viral marketing. However, the use of SNS data for personalised marketing has provoked outrage amongst SNS users and radically highlighted the issue of privacy concern. This paper inverts the traditional approach to personalisation by conceptualising the limits of data mining in social networks using privacy concern as the guide. A qualitative investigation of 95 blogs containing 568 comments was collected during the failed launch of Beacon, a third party marketing initiative by Facebook. Thematic analysis resulted in the development of taxonomy of privacy concerns which offers a concrete means for online businesses to better understand SNS business landscape - especially with regard to the limits of the use and acceptance of personalised marketing in social networks

The Evolution of Social Commerce: The People, Management, Technology, and Information Dimensions

Social commerce is a form of commerce mediated by social media and is converging both online and offline environments. As a relatively new phenomenon, social commerce has evolved quickly in practice, yet has gained little attention in the IS discipline. With its pervasiveness in businesses and people’s lives, social commerce presents ample research opportunities that can have both theoretical and practical significance and implications. This article aims to capture researchers’ attention by describing the characteristics of social commerce and its potential future directions. We trace the evolutionary patterns of social commerce chronologically, based on trade articles and academic publications from 2005 to 2011. A framework that combines people, management, technology, and information dimensions is used to provide a systematic analysis of social commerce development. Our examination shows that since 2005, the year the term social commerce was incepted, assumptions and understanding of people in social commerce move from a simple and general description of human social nature to a rich exploration with different angles from social psychology, social heuristics, national culture, and economic situations. On the management dimension, business strategies and models evolve from the short-tail to long-tail thinking, with invented concepts such as branded social networks/communities, niche social networks/communities, niche brands, co-creating, team-buying, and multichannel social networks. Technologically, IT platforms and capabilities for social commerce evolve from blogs, to social networking sites, to media-sharing sites, and to smartphones. While Facebook becomes a profit-generating platform, creating the notion of f-commerce, Google and Twitter become strong competitors with great potentials. Information in social commerce evolves from peer-generated, to community-generated (crowdsourcing), to consumer and marketer co-created, and to global crowdsourced. Our examination identifies various conceptualizations, terminologies, views, and perspectives about social commerce and its relation to other well-known concepts such as e-commerce. In light of the evolution of social commerce, we provide possible future directions for research and practice
