Joining magnesia partially stabilised zirconia with nickel by current enhancement

This study confirms that current enhancement is a reliable and efficient method for joining ceramic and metal. Experiments indicated very high bond strengths. Mathematical modelling explained the mechanism of joining and has established critical functions for design and control.

Baby, it`s you : international capital discovers the under threes

Well-established international entertainment firms such as Disney and Fisher-Price are joining new start-up firms such as Baby Einstein to create a 'Baby' market of products (including toys, games and videos) specifically targeted at children aged 0-3 years. Despite its novelty, the 'Baby' market mirrors older markets that these firms have created around other demographic groups (e.g. older children, adolescents and adults) - it redefines its target demographic group around specific commodities and promotes its redefinition as 'common sense'. The 'Baby' firms redefine babies solely as early learners whose potential to learn can be released by these firms' brand-name 'educational' or 'developmental' products. Many adults buy these products because they accept the firms' redefinition of babies, but other adults ignore the firms' promotional messages and buy the products to give themselves some time apart from their babies. The 'Baby' market is significant for children and adults because it changes young children's relationships with adults and because it subordinates local cultural differences to a children's culture that purports to be 'global' but has, in reality, extremely narrow foundations in class, race and gender.

Explaining non-renewal behaviour : an empirical investigation of recently lapsed NRL club members

This paper reports on a survey of lapsed members of an Australian professional National Rugby League (NRL) Club. Analysis of the 195 useable responses returned suggest that these lapsed members had originally joined as much for intangible aspects, such as seeking a greater level of involvement with the club, as for the functional aspects such as savings on game entry. Overall, these lapsed members were satisfied with the service they received whilst a member, and claimed it had been performed in line with expectations. The main drivers of satisfaction were also a mix of tangible and intangible factors such as feeling valued by the club and receiving discounts on entry costs. The members gave a number of reasons for not rejoining in 2002, but primarily cited an inability to attend games. Despite joining for intangible reasons, it seems that if these members could not get to games, they perceived that membership was not worth maintaining. That said, a large number of members indicated that as their circumstances change they will rejoin the club, supporting the theory that non-renewal is not driven by service failure, but rather the perception that attendance is still the core product (entertainment). The overall level of satisfaction had a weak but positive relationship with the likelihood of members rejoining in the future.

A defection analysis of lapsed members of five sporting clubs : examining motivations and behaviours

The issue of defection has been examined primarily in a transactional context as opposed to subscription markets where the infrequent nature of the purchase or renewal means that retention of subscribers is often both more difficult and more crucial. This paper reports on a survey that aimed to uncover more information about the motivations and future intentions of recently lapsed subscribers. 1,011 lapsed members across four Australian Football League (AFL) clubs and one Australian National Rugby League (NRL) club were surveyed. Analysis of the responses returned suggests that although these lapsed members report that they joined to financially support and feel more involved with the club, they let their membership lapse primarily due to an inability to attend games. Despite joining for intangible, altruistic reasons, it seems that if these members could not get to games, they believed that the membership was not worth maintaining. These members were satisfied with the membership; however measures of overall level of satisfaction had only a weak positive relationship with the likelihood of members rejoining in the future. The inconsistencies in the findings challenge some conventional approaches to both the methods of researching lapsed members and the theories that are frequently used to explain behaviours. We find that simplistic entry or exit surveys are likely to be of limited value in subscription defection research and that satisfaction is unlikely to be a strong predictor of defection behaviour.

Alternative learning trajectories

Lesson planning usually involves the generation of a hypothetical learning trajectory. This paper illustrates a teaching strategy that is one focus of a major research project. Alternative learning trajectories with different entry level prompts were used to enable students to access the concepts and procedures necessary for their joining the main learning trajectory. The strategy is being trialled in primary classrooms that have a large proportion of lower SES students, with the aim of maximising success in mathematics for all students.

Characterization of melded carbon fibre/epoxy laminates

‘Melding’ is a novel in situ method for joining thermosetting composite structures, without the need of adhesives. Laminate joining is achieved using uncrosslinked resin matrix of the pre-preg. This study used Hexply914C pre-preg material to characterize melded CFRP structures produced using the melding method. A designated area of a laminate was maintained at temperatures below 40 °C retaining uncured (B-staged) material, while the remainder of the laminate was cured at 175 °C. After a 2.5 h cure cycle, the cured region showed a high degree of cure (0.88) and glass transition temperature (176 °C). The uncured area of the same laminate was cured in a second stage, simulating an in situ melded joint. By controlling the temperature and duration of the intermediate dwell and affecting minimum viscosity values prior to final cure, low values of porosity (<0.5%) were achieved. The mechanical properties of the resulting joint were consistent throughout the melded laminate. Flexural strength (1600 MPa), flexural modulus (100–105 MPa) and short beam strength (105–115 MPa) values observed where equivalent or greater than those found in the recommended autoclave cured control specimens. After the entire laminate was post cured, glass transition temperatures of 230 °C (peak tan δ) were observed in all areas of the laminate.

Investigation of processing conditions of melded parts to determine process boundaries

Melding, a novel method for producing seamless joints in thermosetting composites utilising the Quickstep™ process, is explored in this paper. The effect of processing conditions on the quality of melded joins is examined and a set of processing boundaries defined so that the strength of melded joints is optimized. HexPly® 914c pre-preg material was exposed to a range of processing temperatures prior to joining via the melding process. Differential Scanning Calorimetry analysis was carried out to investigate the degree of cure of material prior to final joining, and it was found that minimal cure occurs at temperatures below 120°C. After consolidation and cure of the melded parts, short beam shear testing was conducted to evaluate the strength of the melded interface. Exposure temperatures between 65°C and 120°C were found to optimize short beam shear join strength. Mode I double cantilever beam and mode II end notched flexural tests showed no detrimental effect of elevated exposure temperatures prior to joining.

A defection analysis of lapsed season ticket holders : a consumer and organizational study

This paper reports on a four-stage study that investigated the motivations and future intentions of recently lapsed members (season-ticket holders) of professional sports organizations, and the marketing responses of those organizations to the issue of customer retention. Survey responses from over 1,000 recently lapsed members across five large sporting clubs were collected. A further study on one club was then conducted to compare attitudes and demographics of lapsed members to those who renewed. The responses suggests that although these lapsed members report that they joined to financially support and feel more involved with the club, they let their membership lapse primarily due to an inability to attend games. Despite joining for intangible, altruistic reasons, it seems that if these members could not get to games, they believed that the membership was not worth maintaining. These members were satisfied with the membership; however, measures of overall level of satisfaction had only a weak positive relationship with the likelihood of members rejoining in the future. These sport organizations were greatly concerned by lapsed members but have only ad hoc relationship marketing strategies in place to either prevent members lapsing or renew lapsed members.

Think global, act local: from naive comparison to critical participation in the teaching of strategic international human resource management

In this paper, we examine the implications of ethnocentrism and paternalism in teaching approaches for the field of strategic international human resource management (SIHRM), as an example of management studies. We argue that the teaching of SIHRM has been approached in a colonizing fashion, joining and extending the territories of human resource management and organizational strategy through the definition and teaching of a new language and conceptual vocabulary. We explore philosophical approaches and processes involved in teaching SIHRM, and consider implications of pedagogical developments in this field of management education.

Indo-US strategic ties on the upswing

Strategic ties based on converging national interests shared perceptions of the evolving Asia-Pacific security environment are strengthening between India and USA. The sanctions imposed in response to IndiaEs 1998 nuclear tests were relaxed and military-to-military links were stored with the joining of India in US-led war on terror.

People, places and public health : evaluating the benefits of civic environmentalism in an urban local government context

Recent political, economic and social trends pose threats to the sustainability both of ecosystems and of human health. Australia’s environmental management record is poor, and while by international standards Australians enjoy good health, this is variable (AIHW, 2000). Within developed nations, heart disease, depression, alcohol dependence and stroke are major health issues (Mathers et al. 2002). In Australia, mental disorder is the number one contributor to the disease burden (Vos & Mathers 2000). Recent research has highlighted the role of social capital as a key determinant of health (Kawachi et al., 1997). Despite this, Putnam (1995) observes that social connectedness and civic engagement are in decline. People have less time for leisure and for volunteering, as many juggle paid work and caring for children. Anecdotal evidence suggests that engagement in civic environmentalism has human health benefits, relating to a combination of exposure to natural environments and increased social capital (Maller, Brown, Townsend & St. Leger, 2002). This link is supported by Furnass (1996) who defines well-being as including: satisfactory human relationships, meaningful occupation, opportunities for contact with nature, creative expression, and making a positive contribution to human society. Research conducted by Deakin University confirms the efficacy of linking people and places through civic environmentalism for addressing both ecosystem sustainability and human health and wellbeing. The research has included a pilot study to explore the human health benefits of membership of a local parkland ‘Friends’ group, and a more detailed follow-up study. The aims of the pilot study included:- To identify the range of motivations for joining the Friends group;- To document members’ perceptions of the benefits gained from membership of the group;- To assess the potential for Friends groups to be used as an ‘upstream’ health promotion measure.Face-to-face interviews were conducted with eleven members of a ‘Friends’ group in the eastern suburbs of Melbourne. Data was analysed thematically and key findings included:- Motivations: environmental; social; and pragmatic.- General benefits: community belonging; personal satisfaction; learning opportunities; physical activity; and better environment.- Health benefits: physical health; mental health; and social support. There was unanimous support for the use of ‘Friends’ groups as a tool for health promotion.The follow-up study, in the western suburbs of Melbourne, expanded on the pilot study by measuring the group’s social capital and by collecting self-report data on levels of health service usage. Data was collected through face-to-face interviews and a questionnaire. The findings were similar to the pilot study in relation to the motivations, benefits and the health promotion potential of such groups. However, health service usage data highlighted an apparent anomaly: while respondents perceived significant health benefits, some were nevertheless utilising health services at a relatively high level. This poses some questions requiring further exploration: Is this due to the poorer baseline health of the high health service usage members compared with their fellow members? Does involvement in the group offer health benefits that enable people who would otherwise be too unhealthy to participate in community groups to continue such involvement?If this is the case, then we may do well to look to locally-based mechanisms for promoting ecological sustainability as a tool also for promoting human health. Instead of prescribing a pill, connecting people and places through engagement with a local friends group may address our health problems at the same time as addressing local environmental problems.

Melding: a new alternative to adhesive bonding

Melding, a novel method for joining composites is examined in this paper. The method uses Quickstep ™ technology to retain partially cured areas of a composite laminate, enabling subsequent bonding operations. The effect of melding on the mechanical properties of the composite has been investigated. Flexural testing of HexPly 914 indicates consistent properties throughout a melded section. Flexural strength values of 1.36±O.03 GPa compared to 1.35±O.03 GPa for a standard laminate were recorded. In order to achieve sufficient bond strength, the portion of the composite to be joined must have a significant proportion of uncured matrix. The ability of Hexply 914 prepreg to retain sufficient bonding potential to form a strong joint was also investigated. HexPly 914 Lap Shear results indicated no significant variation in strength values between co-cured and melded joins, with a recorded
strength value of 15.0±0. 7 MPa.

The role of emotions in member renewal and non-renewal : an exploratory study

This paper examines the emotions of lapsed and continuing members of a high involvement, subscription based organisation. In-depth interviews were conducted with 400 renewing and non-renewing members of an Australian Football League Club in order to gain initial insight into the role emotions play in renewal (loyalty) behaviours. The interviews highlighted the complexity of the relationship between emotions and behaviours. There is a range of both positive and negative emotions present in responses of both renewing and non-renewing members. As expected, the negative emotions of disappointment and frustration were present amongst those who did not renew, while there were many positive emotion examples of satisfaction and joy present for those who had renewed. Surprisingly, there were also examples of annoyance, fear, and guilt amongst those that had renewed. These feelings were often linked to the particular member's history and level of family involvement in the Club over many years. In addition, there were positive feelings of hope and loyalty expressed by those respondents that had not renewed. On a positive note for the Club, many still expressed a strong emotional connection to the Club and had not ruled out joining again in the future.

Understanding cross-cultural negotiation : A model integrating affective events theory and communication accommodation theory

Business interactions are increasingly crossing boundaries. Boundary crossing is a process of joining or parting people. Negotiation is the media of this process. This paper is an attempt to bridge the boundaries of strategic business negotiation, communication and emotion in a cross-cultural context. In particular, we argue that miscommunications are ‘boundary crossing mishaps’. Such mishaps are affected by negotiators’ understanding of the respective cultures of the parties, negotiation skill, affective cultural background of the parties, cultural differences, emotional awareness and regulation, negative affect and discrepancy in convergence divergence between the interactants. When too many of these hassles or mishaps occur, negotiation breaks down. In this way, it is the accumulation of many little things, many little misunderstandings, that break negotiation.
