Resisting immigrant myths : everyday consumer practices of Asian immigrants in America

Projective, depth interviews with U.S. Asian immigrants revealed their ambivalence toward the U.S. commercial sector’s colonial-era representations of Asian people. These commercial representations provide polarized depictions of Asian immigrants as either threatening aliens or as model citizens. These portrayals reflect “racialized otherness,” or racial stereotyping that represent Asian immigrants as inferior. Our findings indicate that Chinese immigrants strategically use everyday consumption related to foodways to resist the reverberation of American immigrant myths. In some instances, immigrants’ consumption practices instantiate a regional Asian identity. In other instances, however, immigrants’ consumption practices reflect a separation from the past and an acceptance of a new although not exclusively American way of life. Notwithstanding immigrant consumers’ resistance practices, the findings call for future research into immigrant consumers’ reactions to visual representations of race, ethnicity, and gender.

Diversity, ethnicity and consumption

This paper aims to examine diversity and identity issues from a marketing perspective. The traditional marketing practice of segmenting markets could be viewed as the antithesis of diversity as it relies on identifying  homogenous characteristics of a population. It is uneconomical and  generally less effective to market to a broad range of consumers than to do so for a specific group with homogenous characteristics. However, segmentation is not possible without diversify. Segmentation requires the presence of substantial differences in consumer characteristics and behaviour in a population to be truly effective. Marketing and its relationship to diversity, however, extends beyond segmentation and into issues of an individual's sense of identity and belonging. The literature suggests that an individual's identify is expressed through consumption and this can include ethnic identity. With an increasingly diverse, multicultural society in many countries, it is timely to look more closely at cultural identity and its relationship to consumption. Hofstede's work on cultural characteristics inherent in a particular country, continue to be widely used in international business. How evel; cultural identity and characteristics attributed to individuals in their country of birth may change when they immigrate to another country. Acculturation in a host country affects how immigrants see themselves and wish to be perceived. This can be problematic for marketers attempting to segment and reach consumers on the basis of their ethnicity. If consumption is an expression of identity as the literature suggests, then marketing has a role to play in either influencing or responding to issues of diversity and identity in the population at large. This paper examines the current literature on consumption, consumer behaviour and ethnic identify.

UV induces resistance in Arabidopsis Thaliana to the Oomycete Pathogen Hyaloperonospora Parasitica

Owing to their sessile nature, plants have evolved mechanisms to minimise the damaging effects of abiotic and biotic stresses. Attack by pathogenic fungi, viruses and bacterium is a major type of biotic stress. To resist infection, plants recognise invading pathogens and induce disease resistance through multiple signal transduction pathways. In addition, appropriate stimulation can cause plants to increase their resistance to future pathogen attack. We have found that exposure to non-lethal doses of UV-C (254 nm) renders a normally susceptible ecotype of Arabidopsis thaliana resistant to the biotrophic Oomycete pathogen Hyaloperonospora parasitica. The UV treatment induces an incompatible response in a dose-dependent fashion, and is still effective upon pathogen inoculation up to seven days after UV exposure. The degree of resistance diminishes with time but higher doses result in greater levels of resistance, even after seven days. Furthermore, the effect is systemic, occurring in parts of the plant that have not been irradiated. Incubation in the dark post?irradiation and prior to infection reduces the UV dose required to generate a specific level of pathogen resistance without affecting the duration of resistance. These observations, plus the inability of plants to photoreactivate UV photoproducts in the dark, strongly suggest that DNA damage induces the resistance phenotype. Currently, we are assessing the influence of DNA repair defects on UV-induced resistance, following the expression of a number of defence?related genes post-UV-C irradiation, and assessing the effect of UV in plant mutants deficient in specific signalling molecules involved in resistance.

Principals and the politics of resistance to change

Governments hold principals accountable for leading and managing significant change for school improvement, primarily demonstrated through enhanced student test results. Research evidence suggests, however, that schools are slow to change, that many individuals are resistant to major change and that school reforms are often cursory or short lived. The stakes for principals to produce measurable improvements are rising, as are disincentives for failure. This article discusses the experiences of Australian principals overseeing major change in the context of rapid structural and policy reform. It focuses specifically on the micro-politics of resistance, through an exploration of principals' experiences and perceptions about leading major change. The article closes with suggestions for future research and leadership practice.

Consumption and the meaning of life

Through an analysis of data from depth interviews with modern American consumers, we examine whether and how individuals quest for life’s meaning through consumption. Our analysis identifies three worldviews that are differently related to the experience of transcendence through consumption. A rationalist worldview is revealed as being unrelated to such a pursuit. It contrasts two magical worldviews held by most informants in which consumption objects are infused with supernatural and metaphysical beliefs that animate life’s meaning for them. Our discussion highlights how recognition of magical worldviews contributes to consumer theory, methods, and concepts of investigation.

Exposure to a high-fat diet alters leptin sensitivity and elevates renal sympathetic nerve activity and arterial pressure in rabbits

The activation of the sympathetic nervous system through the central actions of the adipokine leptin has been suggested as a major mechanism by which obesity contributes to the development of hypertension. However, direct evidence for elevated sympathetic activity in obesity has been limited to muscle. The present study examined the renal sympathetic nerve activity and cardiovascular effects of a high-fat diet (HFD), as well as the changes in the sensitivity to intracerebroventricular leptin. New Zealand white rabbits fed a 13.5% HFD for 4 weeks showed modest weight gain but a 2- to 3-fold greater accumulation of visceral fat compared with control rabbits. Mean arterial pressure, heart rate, and plasma norepinephrine concentration increased by 8%, 26%, and 87%, respectively (P<0.05), after 3 weeks of HFD. Renal sympathetic nerve activity was 48% higher (P<0.05) in HFD compared with control diet rabbits and was correlated to plasma leptin (r=0.87; P<0.01). Intracerebroventricular leptin administration (5 to 100 μg) increased mean arterial pressure similarly in both groups, but renal sympathetic nerve activity increased more in HFD-fed rabbits. By contrast, intracerebroventricular leptin produced less neurons expressing c-Fos in HFD compared with control rabbits in regions important for appetite and sympathetic actions of leptin (arcuate: −54%, paraventricular: −69%, and dorsomedial hypothalamus: −65%). These results suggest that visceral fat accumulation through consumption of a HFD leads to marked sympathetic activation, which is related to increased responsiveness to central sympathoexcitatory effects of leptin. The paradoxical reduction in hypothalamic neuronal activation by leptin suggests a marked “selective leptin resistance” in these animals.

Patterns of resistance in managing assessment change

Achieving change in assessment practices in higher education is difficult. One of the reasons for this is resistance among those responsible for teaching and assessing. This paper seeks to explore this resistance through an analysis of staff dialogue during a major attempt to change the assessment practices at one institution. An institution-wide intervention to pilot new assessment practices was initiated, involving 35 academics across 12 departments. This paper reports on patterns emerging in dialogue about this among academics, and between academics and educational development personnel. Findings suggest that resistance is not a unitary concept, but that different stakeholders under varied circumstances express it differently; and that resistance to assessment change is particularly resilient. Implications are discussed in terms of relevance to current theories of higher education assessment and learning change management, as well as the practical considerations of attempts by institutions to engage in assessment change. © 2013 © 2013 Taylor & Francis.

Tunnelling current recognition through core-satellite gold nanoparticles for ultrasensitive detection of copper ions

We report a new method for ultrasensitive detection of Cu(2+), which is based on changes in the tunnelling recognition current across self-assembled core-satellite gold nanoparticles (GNPs) networks functionalised with amino acids (l-cysteine). The addition of copper ions induces the formation of GNP/l-cysteine/Cu(2+)/l-cysteine/GNP molecular junctions and generates a significant decrease in the resistance through the networks. The networks are ultrasensitive to over ten orders range of copper ion concentrations.

Sports-events, tourism and destination marketing strategies: an Australian case study of Athens 2004 and its media telecast

The focus of this study was the media telecast of the Athens 2004 Summer Olympic Games. The study explored the efficacy of the Australian telecast in developing positive perceptions and attitudes of Greece as a tourist  destination and was origin-based—in that a survey was undertaken of a sample of Australian residents (n = 350). Participants were segmented based on their post-consumption perceptions of Greece. Four segments were identified and labelled—'extremely positive' (n = 75), 'highly positive' (n = 153), 'positive' (n = 83) and 'negative' (n = 29). Statistical differences were found between the segments based on whether attitudes towards Greece had improved as a result of their consumption of the media telecast of the Athens 2004 Olympic Games (Athens 2004). To gain insights into this phenomenon, open-ended responses provided by segment members were then analysed.

Across the sample, 38.7% of respondents indicated that their overall attitude towards Greece as tourist destination changed as a result of their consumption of the telecast of Athens 2004. Considering that the attitudes of participants in the current study improved, not as a result of first-hand experiences at the destination, but as a result of their vicarious experiences of the destination through consumption of a media telecast of a special event, the results provide insights to the efficacy of this particular telecast in developing positive attitudes with regard to Greece as a tourist destination. The results of this study could be used a benchmark for future event-related destination marketing strategies. Similarities and differences emerged between the segments with regard to the reasons as to why members of each of the clusters attitudes towards Greece as a tourist destination had improved as a result of their consumption of the telecast. While their responses appeared to be similar, the frequency in which the concepts emerged for each of the segments varied intensity. The key issues that emerged for the four clusters were the appearance of Greece; culture and history of Greece; capacity, or 'hostability', of Greece to stage the Athens 2004; and infrastructure in Greece.

Detection of endocrine disrupting chemicals in aerial invertebrates at sewage treatment works

Endocrine disrupting chemicals (EDCs) constitute a diverse group of chemical compounds which can alter endocrine function in exposed animals. Whilst most studies have focussed on exposure of wildlife to EDCs via aquatic routes, there is the potential for transfer into the terrestrial food chain through consumption of contaminated prey items developing in sewage sludge and waste water at sewage treatment works. In this study, we determine levels of EDCs in aerial insects whose larval stages develop on percolating filter beds at sewage treatment works. We compare absolute concentrations of known EDCs with those collected from aquatic environments not exposed to sewage effluent outflow. Our findings document for the first time that aerial invertebrates developing on sewage filter beds take up a range of chemicals thought to be incorporated from the sewage effluent, which act as endocrine disruptors. For two synthetic chemicals (17α-ethinylestradiol and butylated hydroxy aniline), concentrations were significantly higher in insects captured around percolating filter beds than sites over 2 km from the nearest sewage works. A number of species of insectivorous bats and birds, some of which are declining or threatened, use sewage works as principle foraging sites. We calculate approximate exposure levels for a species of bat known to forage within sewage works and suggest that further research is warranted to assess the ecological implications of consuming contaminated invertebrate prey

Facile synthesis of graphene oxide hybrids bridged by copper ions for increased conductivity

In this article, we report a facile method for preparing graphene oxide (GO) hybrid materials consisting of copper ions (Cu2+) complexed with GO, where Cu2+ acted as bridges connecting GO sheets. The method of film formation is based on cross-linking GO using Cu2+ followed by filtration onto nanoporous supports. This binding can be rationalized due to the chemical interaction between the functional groups on GO and the metal ion. We observed that there was a decrease in charge transfer resistance through electrochemical study. It suggests that the presence of metal ions in GO films could introduce new energy levels along the electron transport pathway and open up possible conduction channels. We also found that the hybrid graphene film assembled with Cu2+ dramatically decreases resistance through flash light reduction.

Micronutrient supplement use and diet quality in university students

Many national and international public health organisations recommend achieving nutrient adequacy through consumption of a wide variety of nutritious foods. Despite this, dietary supplement sales continue to increase. Understanding the characteristics of micronutrient supplement users and the relationship with diet quality can help develop effective public health interventions to reduce unnecessary consumption of vitamin and mineral supplements. Participants (n = 1306) were a convenience sample of students studying first year food and nutrition. Data was collected via a Food and Diet Questionnaire (FDQ) and a Food Frequency Questionnaire (FFQ). Supplement users were defined as participants who indicated consuming any listed supplement as frequently as once a month or more. Diet quality was assessed using a Dietary Guideline Index (DGI) score. Prevalence of supplement use was high in this study population with 56% of participants reporting supplement use; the most popular supplements consumed were multivitamins (28%) and vitamin C (28%). A higher DGI score was significantly associated with an increased likelihood of supplement use (mean: 105 ± 18 vs. 109 ± 17, p = 0.001). Micronutrient supplement use was associated with a higher DGI score, suggesting that supplements are more likely to be used by those who are less likely to require them.

Restricting prey dispersal can overestimate the importance of predation in trophic cascades

Predators can affect prey populations and, via trophic cascades, predators can indirectly impact resource populations (2 trophic levels below the predator) through consumption of prey (density-mediated indirect effects; DMIEs) and by inducing predator-avoidance behavior in prey (trait-mediated indirect effects; TMIEs). Prey often employ multiple predator-avoidance behaviors, such as dispersal or reduced foraging activity, but estimates of TMIEs are usually on individual behaviors. We assessed direct and indirect predator effects in a mesocosm experiment using a marine food chain consisting of a predator (toadfish--Opsanus tau), prey (mud crab--Panopeus herbstii) and resource (ribbed musse--Geukensia demissa). We measured dispersal and foraging activity of prey separately by manipulating both the presence and absence of the predator, and whether prey could or could not disperse into a predator-free area. Consumption of prey was 9 times greater when prey could not disperse, probably because mesocosm boundaries increased predator capture success. Although predator presence did not significantly affect the number of crabs that emigrated, the presence of a predator decreased resource consumption by prey, which resulted in fewer resources consumed for each prey that emigrated in the presence of a predator, and reduced the overall TMIE. When prey were unable to disperse, TMIEs on mussel survival were 3 times higher than the DMIEs. When prey were allowed to disperse, the TMIEs on resource survival increased to 11-times the DMIEs. We found that restricting the ability of prey to disperse, or focusing on only one predator-avoidance behavior, may be underestimating TMIEs. Our results indicate that the relative contribution of behavior and consumption in food chain dynamics will depend on which predator-avoidance behaviors are allowed to occur and measured.

Consumer construction of sport consumption experiences through role play : a literature review

Evidence exists in the literature that many traditional consumer behaviours have fundamentally different meanings when considered in an experiential context. This paper posits that voicing during the experiential consumption of sport may in fact be a factor of experiential consumption rather than an expression of dissatisfaction as in the traditional complaint behaviour model. This is significant in the interpretation of experiential sport consumption where vocalising appears to serve purposes other than complaining. This paper revises the traditional complaint behaviour literature for explanations about vocalising and then offers some alternate conceptual propositions using experiential consumption literature.
