- Description: Alternanthera philoxeroides is a problematic invasive plant in many regions of the world that is difficult to control once naturalised. It poses a threat to agricultural productivity, biodiversity and social amenity values of aquatic environments. Significant research has been conducted internationally, regarding the efficacy of different herbicides for control of A. philoxeroides. However, no studies have looked at key aspects of control for effective management in an early stage of invasion of aquatic environments, hindering eradication and control programmes. This study evaluates the efficacy of herbicides and surfactants on key A. philoxeroides response metrics, including control of above-ground biomass, below-ground biomass and production of viable stem fragments. This study concluded that glyphosate (isopropylamine salt) minimises viable stem fragment production post-herbicide application, compared with imazapyr and metsulfuron, thus reducing the potential for dispersal throughout catchments and waterways. In contrast, imazapyr and metsulfuron provided more effective control than glyphosate for A. philoxeroides growing on exposed embankments. We propose that an effective management strategy for early invasion of aquatic A. philoxeroides, using herbicides, would be to conduct initial applications of glyphosate to control overwater biomass and limit dispersal of viable stem fragments. Once infestations have been forced back to the embankment, imazapyr or metsulfuron treatments will provide longer term control. © 2017 European Weed Research Society

- Description: Customer retention has received ongoing academic focus and scholars have specifically recognized the importance of customer loyalty within the services sector. There is general agreement within this body of work that achieving customer satisfaction alone is not sufficient to develop customer loyalty, particularly in a competitive business environment. Relationship development between businesses and customers is a key contributor to customer loyalty; however, many of the models that are presented within the literature are either product specific or business to business in nature. This chapter presents the results of an examination of a series of relationship development models that was designed to identify the antecedents of relationship development that are likely to have a positive impact on the delivery of hospitality services. We synthesize the key mediating variables of these models into a single customized model that has the capacity to influence relationship development in a hospitality setting. Within this model we emphasize the importance of trust, commitment and cross cultural communication in order to achieve repeat business and to facilitate positive word of mouth communication. © 2017 by IGI Global.

- Description: The Internet has become an important community communications platform, supporting a range of programs and virtual environments. While there are many ways in which people choose to develop personal interactions over the Internet, one of the most popular manifestations is the creation and maintenance of social relationships using social and dating websites. In this chapter, the collection and use of data from such sites is assessed from an ethical frame, and key concepts such as informed consent, information, comprehension, and voluntariness are outlined.

- Description: The term ‘organisational learning’ was popularised by Peter Senge in ‘The Fifth Discipline’, his seminal book from 1990. Since then, the term has become widely accepted among those interested in organisational learning and change management. However, partly due to the somewhat ambiguous situation which arises in a university which is a ‘learning organisation’ in a different sense, academic staff may experience some confusion when this term is used in a higher education institutional context. Further, the embedded notions of single- and double-loop learning and tacit and explicit knowledge, which are features of organisational learning, are not widely understood by those affected by organisational learning initiatives, leading again to some unintended confusion of purpose in situations of change.

- Description: Consultation between employers and employees is mandated under Australian occupational health and safety legislation. For consultation to be considered meaningful and effective, it is generally accepted that moral and ethical principles such as trust, honesty, commitment and respect need to be recognized and applied by individuals during consultation. It is also considered that an organization's level of cultural maturity is an important element in the ability of individuals to freely engage in meaningful and effective consultation. If the value of consultation is best reflected in the degree of input and control that workers have regarding the very decisions that affect them, and if the level of worker involvement is a reflection of an organization's level of cultural maturity, it is debateable whether the notion of applying moral and ethical principles during consultation, and the adoption of the paradigm of organizational and cultural maturity, have been successfully developed and embraced in the commercial and industrial sector of the construction industry of Victoria, Australia. © 2013 Taylor and Francis Group, LLC.

- Description: In recent years, there has been an increasing number of international students engaged in Doctoral studies in the fields of Hospitality and Tourism at Australian universities. In particular, many students come' from our near neighbours in Asia such as Malaysia and Thailand, which coincidentally reflects the growing number of major international hotel chains establishing or growing their property portfolios across the Asian Pacific region. Whilst the increase in student postgraduate by-research numbers is a welcome and a valuable development for Australian universities, it nevertheless has proved to be somewhat problematic for both the postgraduate student and their supervisors with respect to the pragmatic outcomes of the studies. For example, there is still some uncertainty about the precise nature of the benefits to the student and their home institution, to the hosting university, and to the respective countries, that accrue from these intensive studies. We suggest that, in order to advance our own contributions and impact in this area, there is more work that we need to do in further enhancing or capitalising on the research findings of the studies and the experiences which have attended the students' candidature. We are, therefore, proposing that we need to spend some time reconceptualising the meta meaning of this kind of international research experience at the postgraduate level. In the light of the degree and significance of cultural differences which regularly emerge during the supervision process, and given the paucity of fundamental and applied research into crosscultural hospitality provision, we believe that we need to re-examine the question of how our programs and procedures which are required for postgraduate level studies should be structured to provide both a quality scholarly developmental experience for students in the discipline while simultaneously generating practical benefits for relevant stakeholders, particularly those in the Hospitality industry. Consequently, what we have set ourselves the task of doing here is to focus on the link between the formal intellectual requirements of the doctoral process and the pragmatic interests of the students and all their supporting institutions in order to make more use of the three plus years of engagement with tightly focussed research problems which underpin a postgraduate by-research qualification. Our aims, in terms of the outcomes of this reflection, are to: (i) better understand differences in the nuances of cultural meanings of hospitality and help embed these meanings in future scholarly studies, (ii) contribute to an enhancement of the quality of the Hospitality practices of students' sponsoring institutions as a result of the student's doctoral experience, (iii) make closer ties between the hosting university and relevant authorities who oversee the hospitality standards of neighbouring countries in respect of international visitors, and (iv) develop closer institutional ties with hospitality training organisations, both educational and professional, in these neighbouring countries. Specific issues that will command attention in this reflection will include: the development of theoretical models of hospitality procedures which explicitly involve crosscultural dimensions; clearer definitions of critical processes of hospitality practice which involve cross-cultural understandings such as loyalty, respect, and trust; the development of perspectives on internationalisation in the hospitality industry that can be built into our own practices; and to capitalise upon the areas of difference between Western and Eastern notions of hospitality that can be shared with hospitality providers who seek to develop or enhance cross cultural training programs for their staff.

- Description: Abstract: Australian universities are currently undergoing significant and deep-seated change to their funding models through their relationship to Federal government social development and research agendas. Consequently, changes are being instituted at all levels of university activity. Such changes are often accompanied by considerable disruption to traditional and accepted practices. This has had the effect of introducing unanticipated institutional difficulties and is causing some significant levels of personal uncertainty for staff. We suggest that such difficulties might be mitigated by more effective, efficient and transparent change management strategies.

- Description: A sampling methodology has been devised to facilitate the selection of a purposeful sample of marine parks and sanctuaries for the investigation of their impacts on tourism, local community, and businesses. The methodology is based on multiattribute utility theory used for comparing complex alternatives in decision making and takes into account those key attributes of Victoria's 13 marine national parks and 11 marine sanctuaries that have been identified through both published and draft management plans, government policies, and relevant strategies. The attributes are: tourism services, activities, community engagement, visitation, values, interpretation, access, location, conservation significance, and regional context. Values of each marine protected area are quantified and establishment of a total attribute value score for a "typical area" enables the comparison between individual marine parks and sanctuaries. To strengthen the methodology, a panel of independent experts representing tourism, local government, and community organizations were invited to express their views with regard to these attributes, and their responses have been incorporated into the research.
