Although the importance of situational influences on consumer behaviour has been recognised for some time, little research has been conducted into their effects in hospitality retailing. Over the past decade the Irish theme pub sector has enjoyed extensive growth, which recent studies attribute to the situational components inherent within the environment. This study sought to identify and evaluate the situational components that influence consumers within Irish theme pubs and to gauge the influence of each of the dimensions of an established situational model on customer behaviour among gender and age cohorts. A three phase, mixed method research design was used and respondents were selected from six Irish theme pubs in Melbourne. The study found that both physical and social situational components have a significant influence in attracting, serving and satisfying the needs of consumers.

Data replication is one of the key components in data grid architecture as it enhances data access and reliability and minimises the cost of data transmission. In this paper, we address the problem of reducing the overheads of the replication mechanisms that drive the data management components of a data grid. We propose an approach that extends the resource broker with policies that factor in user quality of service as well as service costs when replicating and transferring data. A realistic model of the data grid was created to simulate and explore the performance of the proposed policy. The policy displayed an effective means of improving the performance of the grid network traffic and is indicated by the improvement of speed and cost of transfers by brokers.

The trend in the automotive industry towards new advanced high strength steels (AHSS), combined with the ongoing reduction in program lead times have increased the need to get tool designs right, first time. Despite the fact that the technology used by sheet metal stamping companies to design and manufacture tooling is advancing steadily, finding optimal process parameters and tool geometries remains a challenge. Consequently, there has been a transition from designs based largely on trial and error techniques and the experience of the stamping engineer, to the increased use of virtual manufacturing and finite element (FE) simulation predictions as an indispensable tool in the design process. This work investigates the accuracy of FE techniques in predicting the forming behavior of AHSS grades, such as TRIP and dual phase, as compared to more commonly used conventional steel grades. Three different methods of simulation, one-step, implicit and explicit techniques, were used to model the forming process for an automotive part. Results were correlated with experimental strain and thickness measurements of manufactured components from the production line.

Purpose – The purpose of this paper is to examine the effect of country of origin (COO) sub-components (i.e. design, assembly and parts), as well as the extent to which consumer ethnocentrism tendencies interact with these COO sub-components for young Chinese consumers with regards to product quality assessments and purchase intentions.

Design/methodology/approach –
A 2?×?2?×?2 factorial experimental design was used to examine the effects of the three sub-components of COO with two levels of sourcing location – Home (China) and Foreign (Germany), for two high involvement products (an automobile and a digital camera). Chinese students in China represented the sample of 272 respondents. MANOVA was used to examine the direct effects and interactions of the three COO components, as well as ethnocentrism, measured using the CETSCALE.

Findings – It was found that the three COO sub-components did not influence young Chinese consumers’ evaluation of product quality or purchase intentions. In addition, consumers’ level of ethnocentrism also did not have a direct effect on perceived product quality or purchase intentions. There was only one statistically significant interaction effect between ethnocentrism and country of parts for one of the two products. As such, COO dimensions and young Chinese consumers’ ethnocentrism appears to have limited influence on their assessments of product quality or purchase intentions. This may occur because young Chinese consumers perceive that hybrid products are the norm for high involvement products in China as these products are all these consumers have experienced.

Originality/value – The findings of this research dispute the commonly held belief and evidence that sub-components of COO have an impact on the perceptions of product quality and purchase intentions. Young Chinese consumers may be different to consumers from western countries because they have been extensively exposed to hybrid products. Given the size and growth potential of China, young Chinese are an important, under-researched segment within the Chinese market.

Powerline corridors through forested ecosystems have been criticised due their potential to fragment the landscape and facilitate the intrusion of undesirable species into natural areas. This study investigates the effects of vegetation management (slashing), on: (1) timing of small mammal recolonisation; (2) vegetation characteristics that drive small mammal responses; and (3) the point where corridor resources are sufficient to provide functional habitat for native species. Small mammal trapping was undertaken within Bunyip State Park, Australia, across three sites, once a month from January 2001 to May 2002 and every 2 months thereafter until January 2004. Changes in vegetation around each trap station were assessed annually in the forest and bi-annually in the corridor. Principal components analysis on the vegetation structural complexity values produced factors for use in species abundance models. Native small mammal species recolonised the corridor 1.5–3.5 years after management and the corridor supported a breeding population of small mammals around 2.5 years post-management. Males however, generally recolonised the corridor first, resulting in a sex-biased population in these areas. Species corridor habitat models for five native and one introduced species suggested cover and shelter were more important in determining corridor use than plant species per se. Powerline corridors have the potential to create a mixture of different successional stages, enhancing habitat availability for many species. However, the intensity of current management needs to be reduced and an integrated approach to management needs to be undertaken if powerline corridors are to continuously provide habitat for native small mammal species.

This study was designed to test the effectiveness of a culturally appropriate diet and lifestyle intervention to treat metabolic syndrome in female Pakistani immigrants residing in Melbourne, Australia. Forty Pakistani women with metabolic syndrome (aged 20-50 years) completed a 12-week culturally appropriate diet and exercise program. Results indicate that, before intervention, participants were sedentary, taking 4000 ± 22.6 steps per day, and had an obese-classified body mass index (BMI) of 29.2 ± 0.46 kg/m2 (BMI was categorized in accordance with guidelines specifically designed for Asians) and high waist circumference of 132 ± 25.95 cm. Participants were hypertensive (systolic, 135 ± 1.3 mm Hg; diastolic, 86 ± 0.68 mm Hg), were dyslipidemic (total cholesterol, 6.8 ± 0.15 mmol/L; triglycerides, 2.9 ± 0.09 mmol/L), and had elevated blood glucose (6.4 ± 0.33 mmol/L) and fasting blood insulin (45 ± 6.3 μU/mL) levels. After the 12-week culturally appropriate intervention, activity increased (8600 ± 596.7 steps per day, P < .05); and BMI (27.8 ± 0.45 kg/m2), blood pressure (systolic, 125 ± 1.4 mm Hg; diastolic, 80 ± 0.6 mm Hg), cholesterol (5.5 ± 0.1 mmol/L), blood glucose (5.9 ± 0.33 mmol/L), and blood insulin (24.14 ± 1.8 μU/mL) levels were all significantly reduced (P < .05). This study revealed that the Pakistani female migrants who had metabolic syndrome and its components can successfully be treated via a culturally appropriate diet and lifestyle intervention. The success of the current program raises the possibility that other high-risk ethnic groups can also be treated with a culturally appropriate program.

This study examined the role of positive and negative appearance-based comments on body dissatisfaction and drive for muscularity among young adult males. The direct and moderating effect of self-esteem were also investigated; and BMI, age, and social desirability were included as covariates. The participants were 214 males aged between 18 and 30 years. More frequent negative comments were associated with higher body dissatisfaction whilst more frequent positive comments were associated with lower body dissatisfaction. However, both frequent negative and positive commentary were associated with higher drive for muscularity. Self-esteem was also associated with both body dissatisfaction and the drive for muscularity, but it did not moderate that influence of either positive or negative messages. Longitudinal research is now needed to determine the directionality of these relationships. Further research is required to establish the contexts in which positive and negative messages are associated with body dissatisfaction and the drive for muscularity.

This paper presents a simple and available system for manipulation of heavy tools by low powered manipulator for industrial applications. In the heavy manufacturing industries, sometimes, heavy tools are employed for different types of work. But the application of robots with heavy tools is not possible due to the limited torque limits of actuators. Suspended tool systems (STS) have been proposed to manipulate heavy tools by low powered robot-arm for this purpose. A low powered five-bar direct-drive parallel manipulator is designed and constructed to manipulate heavy tools suspended from a spring balancer. The validity, usefulness, and effectiveness of the suspended tool system are shown by experimental results.

In this paper, we consider daily financial data from various sources (stock market indices, foreign exchange rates and bonds) and analyze their multiscaling properties by estimating the parameters of a Markov-switching multifractal (MSM) model with Lognormal volatility components. In order to see how well estimated models capture the temporal dependency of the empirical data, we estimate and compare (generalized) Hurst exponents for both empirical data and simulated MSM models. In general, the Lognormal MSM models generate "apparent" long memory in good agreement with empirical scaling provided that one uses sufficiently many volatility components. In comparison with a Binomial MSM specification [11], results are almost identical. This suggests that a parsimonious discrete specification is flexible enough and the gain from adopting the continuous Lognormal distribution is very limited.

Response surface methodology was used to optimize the fermentation medium for enhancing naringinase production by Staphylococcus xylosus. The first step of this process involved the individual adjustment and optimization of various medium components at shake flask level. Sources of carbon (sucrose) and nitrogen (sodium nitrate), as well as an inducer (naringin) and pH levels were all found to be the important factors significantly affecting naringinase production. In the second step, a 22 full factorial central composite design was applied to determine the optimal levels of each of the significant variables. A second-order polynomial was derived by multiple regression analysis on the experimental data. Using this methodology, the optimum values for the critical components were obtained as follows: sucrose, 10.0%; sodium nitrate, 10.0%; pH 5.6; biomass concentration, 1.58%; and naringin, 0.50% (w/v), respectively. Under optimal conditions, the experimental naringinase production was 8.45 U/mL. The determination coefficients (R 2) were 0.9908 and 0.9950 for naringinase activity and biomass production, respectively, indicating an adequate degree of reliability in the model.

Animal color pattern phenotypes evolve rapidly. What influences their evolution? Because color patterns are used in communication, selection for signal efficacy, relative to the intended receiver's visual system, may explain and predict the direction of evolution. We investigated this in bowerbirds, whose color patterns consist of plumage, bower structure, and ornaments and whose visual displays are presented under predictable visual conditions. We used data on avian vision, environmental conditions, color pattern properties, and an estimate of the bowerbird phylogeny to test hypotheses about evolutionary effects of visual processing. Different components of the color pattern evolve differently. Plumage sexual dimorphism increased and then decreased, while overall (plumage plus bower) visual contrast increased. The use of bowers allows relative crypsis of the bird but increased efficacy of the signal as a whole. Ornaments do not elaborate existing plumage features but instead are innovations (new color schemes) that increase signal efficacy. Isolation between species could be facilitated by plumage but not ornaments, because we observed character displacement only in plumage. Bowerbird color pattern evolution is at least partially predictable from the function of the visual system and from knowledge of different functions of different components of the color patterns. This provides clues to how more constrained visual signaling systems may evolve.

This thesis is based on fieldwork I carried out between December 1987 and June 1989 while living with the residents of a small Warlpiri Outstation Community situated ca. 75 km north-west of Tennant Creek in the Northern Territory of Australia. Colonialism is a process whereby incommensurate gender regimes impact differently on women and men and this is reflected in the indigenous response which affects the socialization of Western things. The notion of the indigenous KIRDA-KURDUNGURLU reciprocity is shown to be consistent with a gender system and to articulate all exchange relations as pro-creative social relationships. This contrasts with the Western capitalist system of production and social reproduction of gendered individuals in that it does not ascribe gender to biological differences between women and men but is derived from a land based social division between Sister-Brother. Social relationships are put under great strain in an effort to socialize Western things for Warlpiri internal use, I argue that the colonization of Aboriginal societies is an ongoing process. Despite the historical shift from a physical all-male frontier to the present day cross-cultural negotiations between Aborigines and Non-Aborigines, men still privilege men. The negotiation process for ownership of a Community Toyota is the most recent phenomenon where this can be observed. Male privilege is established by linking control over the access to the Community Toyota with traditional rights to land. However, the Toyota as Western object has a Western gender identity as well. By pitting women against men it engages people in social conflict which is brought into existence through an organisation of Western concepts based on an alien gender regime. But Western things, especially the Community Toyota, resist socialization because the Warlpiri do not produce these things. Warlpiri people know this and, to satisfy their need for Western things, they engage them in a process of social differentiation. By this process they can be seen actively to maintain the Western system in an effort to maintain themselves as Warlpiri and to secure the production of Western things. This investigation of the cultural response to Western influences shows that indigenous gender relations are only maintained through a socially stressful process of socializing Western things.
