Cross-cultural issues and research are fundamental to much tourism marketing and especially to developing international tourist markets for cultural events and festivals. With increasing globalization aided by developments in travel and information technology, growing international tourist markets present potentially significant and increasing market opportunities for cultural events throughout the world. In an increasingly competitive marketplace, in order to attract tourist markets, events and festivals need an understanding of these markets and the relevant marketing theories, practices, and strategies. Understanding tourists’ motivation and behavior is essential to identifying attractive tourist market segments in the first instance and then to developing appropriate marketing strategies to attract these segments. Within this environment, the importance of cross-cultural issues and research to tourism marketing and the development of tourist markets are apparent, and yet cross-cultural tourism research to date has been limited. Cross-cultural tourism research in relation to cultural events is even more limited. Cross-cultural tourism marketing research also presents some unique challenges, numerous environmental and methodological problems, and associated costs. These numerous problems, challenges, and costs may in their own right prevent cross-cultural issues and problems from being investigated. Some of these problems can also make the results of some of the existing crosscultural research suspect. Such problems could well account for the limited amount of cross-cultural tourism marketing research that has been undertaken, even though the potential benefits from such research can be great. This article examines the use and application of cross-cultural tourism research by cultural events. It also outlines some of the unique challenges, issues, and problems that need to be addressed in future crosscultural tourism marketing research to improve its application, use, and findings, and ensure the benefits outweigh the costs.

Novel members of the bacterial genus Brucella have recently emerged as pathogens of various marine mammal species and as potential zoonotic agents. We investigated the epizootiology of Brucella infection in Australian fur seals (Arctocephalus pusillus doriferus) by establishing demographic and temporal variations in antibody prevalence, attempting isolation of the causative agent, and determining whether this potential pathogen is involved in frequent abortions observed in this pinniped species. Two competitive enzyme-linked immunosorbent assays (cELISAs), an indirect ELISA, and a fluorescence polarization assay (FPA) were used to test sera for Brucella antibodies. The FPA and cELISA proved suitable for use in this species. Significant differences in antibody prevalence were found between age classes of seals sampled between 2007 and 2009 at one colony. Pups sampled at this site (n5134) were negative for Brucella antibodies by all serologic tests but 17 of 45 (38%) of juveniles were antibody-positive. Antibody prevalence in adult females was significantly higher than in juveniles (P50.044). Antibody prevalence for adult females between 2003 and 2009 varied significantly over time (P50.011), and for individuals sampled between 2003 and 2005, the likelihood of pregnancy was greater in individuals positive for Brucella antibodies (P50.034). Inflammatory lesions suggestive of infectious agents were found in 14 of 39 aborted Australian fur seal pups, but pathologic changes were not uniformly consistent for Brucella infection. Culture and PCR investigations on fetal tissues were negative for Brucella. Culture and PCR on selected fresh or frozen tissues from 36 juvenile and adult animals were also negative. We suspect that the prevalence of active infection with Brucella in Australian fur seals is low relative to antibody prevalence. © Wildlife Disease Association 2011.

Climatic conditions in Australia are erratic and characterised by periods of intense rainfall followed by periods of intense drought. This has considerable impact on the population dynamics and ecology of many Australian species of waterfowl, which are thought to form the reservoir of avian influenza viruses (AIV) but may also be important carriers (and possibly reservoirs) of other diseases (e.g. bursal disease, Newcastle disease). During the wet, waterfowl numbers increase with many serologically naive juveniles entering the population. During the subsequent period of drought, bird densities increase in the few remaining wetlands. We hypothesise that it is during this period of increasing densities of naive birds that the population’s viral prevalence of some infectious diseases may increase dramatically. Indeed, there exists a remarkable and suggestive coincidence between outbreaks of fowl plaque and Newcastle disease in Australian poultry farms and the periods of drought following a very wet period. In other words, we suspect a link between increased risk for disease outbreaks in poultry farms and the hypothesised high in the prevalences of the viruses causing these diseases in waterfowl. Given that poultry farms may provide ideal conditions for development of high-pathogenic strains, there is also a reciprocal risk for wildlife involved during these periods.

Universal access to elementary schooling is a goal that was largely achieved in western democracies by the mid twentieth century. Yet, at the beginning of the twenty-first century, students’ access to schooling appears to be back on the agenda; this time, students themselves rather than our social systems are regulating their access to school. Increasingly, schools throughout Australia and in several other OECD countries are recording a worrying decline in student attendance in the compulsory years, prompting a certain amount of societal ‘fear’, ‘anxiety’ and ‘moral panic’. This paper reviews the literature on student attendance and absenteeism as a feature of contemporary schooling. It begins with an account of how this literature variously defines absenteeism – its discursive categories – and where it locates the ‘problem’. The ‘solutions’ that flow from these accounts are also explicated, specifically in relation to their regulatory effects on students and on the education they are offered. The paper’s critical reading of these problems of and solutions for student absenteeism seeks to highlight the institutional authoring of such student behaviour and of students as ‘other’. It also uncovers the silences in the literature, particularly in relation to cultural difference, student subjectivity and teacher pedagogy – what teachers are doing (and not doing) to/with students. The paper concludes that issues of low socio-economic status do not feature very loudly in the literature (and, we suspect, in practice), despite being strongly associated with students who respond to the demands and relevance of schooling by ‘talking with their feet’.

The purpose of this paper is to provide some guidance to police interviewers and trainers in relation to improving the legal aspects of police questioning of suspects. The paper is written with reference to Victorian legislation. Sixteen professionals (defence barristers, academics, prosecutors, and detectives), all with extensive knowledge of the law and experience evaluating police interviews with suspects, took part in individual indepth interviews (M ¼ 100 minutes). The aim of the interviews was to discuss the limitations of police interviews with suspects and to provide exemplars of concerns from a set of de-identified transcripts that had been provided to the professionals prior to their interviews with us. Overall, four key limitations were raised: (a) inadequate particularisation of offences, (b) inappropriate phrasing of questions, (c) poor introduction of allegations, and (d) questions that unfairly ask the suspect to comment on the victim’s perspective. These concerns and their practical implications are discussed.

1. Whereas the effects of density-dependent growth and survival on population dynamics are well-known, mechanisms that give rise to density dependence in animal populations are not well understood. We tested the hypothesis that the trade-off between growth and mortality rates is mediated by foraging activity and habitat use. Thus, if depletion of food by prey is density-dependent, and leads to greater foraging activity and risky habitat use, then visibility and encounter rates with predators must also increase.

2. We tested this hypothesis by experimentally manipulating the density of young rainbow trout (Oncorhynchus mykiss) at risk of cannibalism, in a replicated single-factor experiment using eight small lakes, during an entire growing season.

3. We found no evidence for density-dependent depletion of daphnid food in the near-shore refuge where most age-0 trout resided. Nonetheless, the proportion of time spent moving by individual age-0 trout, the proportion of individuals continuously active, and use of deeper habitats was greater in high density populations than in low density populations. Differences in food abundance among lakes had no effect on measures of activity or habitat use.

4. Mortality of age-0 trout over the growing season was higher in high density populations, and in lakes with lower daphnid food abundance. Therefore, population-level mortality of age-0 trout is linked to greater activity and use of risky habitats by individuals at high densities. We suspect that food resources were depleted at small spatial and temporal scales not detected by our plankton sampling in the high density treatment, because food-dependent activity and habitat use by age-0 trout occurs in our lakes when food abundance is experimentally manipulated

Phishing emails cause enormous losses to both users and organisations. The goal of this study is to determine which individuals are more vulnerable to phishing emails. To gain this information an experiment has been developed which involves sending phishing email to users and collecting information about users. The detection deception model has been applied to identify users’ detection behaviour. We find that users who have less email experience and high levels of submissiveness have increased susceptibility. Among those, users who have high susceptibility levels and high openness and extraversion are more likely to carry on the harmful action embedded in phishing emails.

For successful prosecution of sex offences, defined elements that comprise each charge (such as the acts that occurred and offenders’ identities) need to be established beyond reasonable doubt. This study explored the potential benefit (from a prosecution perspective) of eliciting another type of evidence; evidence regarding the relationship between the victim and perpetrator that may explain the victim’s responses.

Fourteen prosecutors representing every major Australian jurisdiction participated in individual interviews or a focus group where they were asked to reflect on the perceived relevance of relationship evidence in sex offence trials, and the potential impact of this evidence on court process and outcomes.

All prosecutors gave strong support for the premise of including relationship evidence in victim and witness statements, as well as in suspect interviews; however, this type of evidence was not routinely being included in interviews or admitted in trials.

The majority of the discussion centred on:

(a) the benefits and prevalence of eliciting relationship evidence;
(b) how relationship evidence is best elicited in police interviews; and
(c) challenges in presenting relationship evidence at trial.

Each of these areas, their practical implications and directions for future research are briefly discussed.

Facebook disseminates messages for billions of users everyday. Though there are log files stored on central servers, law enforcement agencies outside of the U.S. cannot easily acquire server log files from Facebook. This work models Facebook user groups by using a random graph model. Our aim is to facilitate detectives quickly estimating the size of a Facebook group with which a suspect is involved. We estimate this group size according to the number of immediate friends and the number of extended friends which are usually accessible by the public. We plot and examine UML diagrams to describe Facebook functions. Our experimental results show that asymmetric Facebook friendship fulfills the assumption of applying random graph models.

Even with the presence of modern obstetric care, stillbirth rate seems to stay stagnant or has even risen slightly in countries such as England and has become a significant public health concern [1]. In the light of current medical research, maternal risk factors such as diabetes and hypertensive disease were identified as possible risk factors and are taken into consideration in antenatal care. However, medical practitioners and researchers suspect possible relationships between trends in maternal demographics, antenatal care and pregnancy information of current stillbirth in consideration [2]. Although medical data and knowledge is available appropriate computing techniques to analyze the data may lead to identification of high risk groups. In this paper we use an unsupervised clustering technique called Growing Self organizing Map (GSOM) to analyse the stillbirth data and present patterns which can be important to medical researchers.

This paper reports the increasing popularity of outsourcing academic works by university students motivated by the lure of lucrative dividends and visa opportunities. Due to a lack of formal methods in detecting such transactions, freelance websites are thriving in facilitating the trade of outsourced assignments. This is compounded by the fact that many university staff have neither the time nor training to perform complex media analysis and forensic investigations. This paper proposes a method to aid in the identification of those who outsource assignment works on the most popular site freelancer.com. We include a recent real-world case study to demonstrate the relevancy and applicability of our methodology. In this case study, a suspect attempts to evade detection via use of anti-forensics which demonstrates the capability and awareness of evasion techniques used by students.

Existing econometric approaches for studying price discovery presume that the number of markets are small, and their properties become suspect when this restriction is not met. They also require making identifying restrictions and are in many cases not suitable for statistical inference. The current paper takes these shortcomings as a starting point to develop a factor analytical approach that makes use of the cross-sectional variation of the data, yet is very user-friendly in that it does not involve any identifying restrictions or obstacles to inference.

BACKGROUND: It is estimated that around 4% of the population engages, or has engaged, in deliberate non-suicidal self-injury. In clinical samples, the figures rise as high as 21%. There is also evidence to suggest that these figures may be increasing. A family member or friend may suspect that a person is injuring themselves, but very few people know how to respond if this is the case. Simple first aid guidelines may help members of the public assist people to seek and receive the professional help they require to overcome self-injury.

METHODS: This research was conducted using the Delphi methodology, a method of reaching consensus in a panel of experts. Experts recruited to the panels included 26 professionals, 16 people who had engaged in self-injurious behaviour in the past and 3 carers of people who had engaged in self-injurious behaviour in the past. Statements about providing first aid to a person engaged in self-injurious behaviour were sought from the medical and lay literature, but little was found. Panel members were asked to respond to general questions about first aid for NSSI in a variety of domains and statements were extracted from their responses. The guidelines were written using the items most consistently endorsed by the consumer and professional panels.

RESULTS: Of 79 statements rated by the panels, 18 were accepted. These statements were used to develop the guidelines appended to this paper.

CONCLUSION: There are a number of actions which are considered to be useful for members of the public when they encounter someone who is engaging in deliberate, non-suicidal self-injury. These guidelines will be useful in revising curricula for mental health first aid and NSSI first aid training programs. They can also be used by members of the public who want immediate information about how to assist a person who is engaging in such behaviour.

This paper studied sales of BP branded gasoline in the United States of America prior, during and after the 2010 BP Deepwater Horizon oil spill accident. The research was funded by the Centre for Sustainable and Responsible Organisations at Deakin University. In what is perhaps the first behavioral study of consumer boycott using market level data, we found that consumers’ with geographic proximity to the accident were more likely to boycott the BP brand. In States that bordered or were close to the Gulf of Mexico, BP sales experienced a small but significant decline as compared to sales in States farther away. The small effect is surprising. We suspect this may be related to the inelastic nature of the product category and the high degree of product homogeneity within the category. It appears that consumers’ and the media’s vocalized outrage over the Deepwater Horizon accident did not result in significant changes in purchase behavior. As such, while consumers were outraged by BP’s actions, they continued to purchase the BP brand. Consumers who lived farther from the spill did not appear to alter their buying patterns even in the short-term, despite being exposed to similar media coverage and high levels of negative public sentiment. In examining changes in BP brand-share with both positive (i.e., claims of success in dealing with the spill) and negative events (evidence that attempts to stop the spill failed), we observed some associations between these events and changes in buying behavior. In States close to the accident, BP purchases increased with good news, market share declined with bad news. No apparent correlation was seen in States that were farther from the accident.

The introduction of profiling systems with increased sensitivity has led to a concurrent increase in the risk of detecting contaminating DNA in forensic casework. To evaluate the contamination risk of tools used during exhibit examination we have assessed the occurrence and level of DNA transferred between mock casework exhibits, comprised of cotton or glass substrates, and high-risk vectors (scissors, forceps, and gloves). The subsequent impact of such transfer in the profiling of a target sample was also investigated. Dried blood or touch DNA, deposited on the primary substrate, was transferred via the vector to the secondary substrate, which was either DNA-free or contained a target sample (dried blood or touch DNA). Pairwise combinations of both heavy and light contact were applied by each vector in order to simulate various levels of contamination. The transfer of dried blood to DNA-free cotton was observed for all vectors and transfer scenarios, with transfer substantially lower when glass was the substrate. Overall touch DNA transferred less efficiently, with significantly lower transfer rates than blood when transferred to DNA-free cotton; the greatest transfer of touch DNA occurred between cotton and glass substrates. In the presence of a target sample, the detectability of transferred DNA decreased due to the presence of background DNA. Transfer had no impact on the detectability of the target profile, however, in casework scenarios where the suspect profiles are not known, profile interpretation becomes complicated by the addition of contaminating alleles and the probative value of the evidence may be affected. The results of this study reiterate the need for examiners to adhere to stringent laboratory cleaning protocols, particularly in the interest of contamination minimisation, and to reduce the handling of items to prevent intra-item transfer.
