In vitro induction of lymph node cell proliferation by mouse bone marrow dendritic cells following stimulation with different Echinococcus multilocularis antigens

The immune response of mice experimentally infected with Echinococcus multilocularis metacestodes becomes impaired so as to allow parasite survival and proliferation. Our study tackled the question on how different classes of E. multilocularis antigens (crude vesicular fluid (VF); purified proteinic rec-14-3-3; purified carbohydrate Em2(G11)) are involved in the maturation process of bone-marrow-derived dendritic cells (BMDCs) and subsequent exposure to lymph node (LN) cells. In our experiments, we used BMDCs cultivated from either naïve (control) or alveolar echinococcosis (AE)-infected C57BL/6 mice. We then tested surface markers (CD80, CD86, MHC class II) and cytokine expression levels (interleukin (IL)-10, IL-12p40 and tumour necrosis factor (TNF)-α) of non-stimulated BMDCs versus BMDCs stimulated with different Em-antigens or lipopolysaccharide (LPS). While LPS and rec-14-3-3-antigen were able to induce CD80, CD86 and (to a lower extent) MHC class II surface expression, Em2(G11) and, strikingly, also VF-antigen failed to do so. Similarly, LPS and rec-14-3-3 yielded elevated IL-12, TNF-α and IL-10 expression levels, while Em2(G11) and VF-antigen didn't. When naïve BMDCs were loaded with VF-antigen, they induced a strong non-specific proliferation of uncommitted LN cells. For both, BMDCs or LN cells, isolated from AE-infected mice, proliferation was abrogated. The most striking difference, revealed by comparing naïve with AE-BMDCs, was the complete inability of LPS-stimulated AE-BMDCs to activate lymphocytes from any LN cell group. Overall, the presenting activity of BMDCs from AE-infected mice seemed to trigger unresponsiveness in T cells, especially in the case of VF-antigen stimulation, thus contributing to the suppression of clonal expansion during the chronic phase of AE infection.

Evidence for an encounter expectancy bias in fear of spiders.

Whereas research has demonstrated that phobic or fearful individuals overestimate the likelihood of incurring aversive consequences from an encounter with feared stimuli, it has not yet been systematically investigated whether these individuals also overestimate the likelihood (i.e., the frequency) of such encounters. In the current study, spider-fearful and control participants were presented with background information that allowed them to estimate the overall likelihood that different kinds of animals (spiders, snakes, or birds) would be encountered. Spider-fearful participants systematically overestimated the likelihood of encountering a spider with respect to the likelihood of encountering a snake or a bird. No such expectancy bias was observed in control participants. The results thus strengthen our idea that there indeed exist two different types of expectancy bias in high fear and phobia that can be related to different components of the fear response. A conscientious distinction and examination of these two types of expectancy bias are of potential interest for therapeutic applications.

The other on display: translation in the Ethnographic Museum

The ethnographic museum in the West has a long and troubling history. The display of 'exotic peoples' in travelling exhibitions began as early as the sixteenth century, but it was the mid and late nineteenth century that saw the great expansion of museums as sites to show artefacts collected - under anything but reputable circumstances - from what were considered the 'primitive', 'natural', or 'tribal' peoples of the world. Today the ethnographic museum is still a feature of large European cities, though faced with newly formulated dilemmas in the postcolonial world. For how can the material culture of a non-western people be collected and displayed in the West without its makers being translated into wordless and powerless objects of visual consumption? In national museums the processes of choosing, contextualizing and commentating exhibits help form national identity; in the ethnographic museum, similarly, they shape perceptions of the apparently distant Other. Like written ethnography, the museum is a 'translation of culture', with many of the associated problems traced by Talal Asad (1986). Like the written form, it has to represent the dialogic realities of cultural encounters in a fixed and intelligible form, to propose categories that define and order the material it has gathered. As the public face of academic ethnography, the museum interprets other cultures for the benefit of the general reader, and in that task museum practice, like all ethnography, operates within very specific historical and political parameters. How are museums in western Europe responding to the issues raised by critical ethnographers like James Clifford (1988), with their focus on the politics of representation? Is globalisation increasing the degree of accountability imposed on the ethnographic museum, or merely reinforcing older patterns? What opportunities and problems are raised by the use of more words - more 'translation' in the narrower sense - in ethnographic museums, and how do museums gain from introducing a reflexive and contextualizing concept of "thick translation" (Appiah 1993) into their work of interpretation?

Questioning in simulated accountant-client consultations:exploring implications for ESP teaching

The field of accountancy plays a vital role in the financial health of modern-day economies. It also attracts very large numbers of students, many for whom English is not their first language, who train in a variety of undergraduate and postgraduate programs at English-medium universities. Yet, surprisingly, the discourse of accountants has been under-reported in the ESP literature (Burns & Moore, 2007a). This paper reports research investigating spoken accounting discourse derived from simulated accountant–client consultations. It draws on the work of Drew and Heritage (1992), in which questioning is identified as a key discursive feature in institutional talk, and also the more recent work reported in Heritage and Maynard (2006), in which the complexity of the formulation of questions and responses is revealed in doctor–patient consultations. The paper discusses the use of simulations in cases where access to actual workplace settings by ESP teachers is unattainable, as well as the usefulness of the interactional data these simulations generate. The paper reports a questioning typology, derived from the data, showing six typical question types found in advice-giving simulated encounters in accountant–client taxation-based consultations: information; clarification; client-specified; backchannel; discourse-related; and interpersonal. The paper concludes with a discussion of the implications of this research for ESP teaching.

Navigating racial boundaries: The one-drop rule and mixed-race Jamaicans in South Florida

Like many West Indians, mixed-race Jamaican immigrants enter the United States with fluid notions about race and racial identifications that reflect socio-political events in their home country and that conflict with the more rigid constructions of race they encounter in the U.S. This dissertation explores the experiences of racially mixed Jamaicans in South Florida and the impact of those experiences on their racial self-characterizations through the boundary-work theoretical framework. Specifically, the study examines the impact of participants’ exposure to the one-drop rule in the U.S., by which racial identification has been historically determined by the existence or non-existence of black forebears. Employing qualitative data collected through both focus group and face-to-face semi-structured interviews, the study analyzes mixed-race Jamaicans’ encounters in the U.S. with racial boundaries, and the boundary-work that reinforces them, as well their response to these encounters. Through their stories, the dissertation examines participants’ efforts to navigate racial boundaries through choices of various racial identifications. Further, it discusses the ways in which structural forces and individual agency have interacted in the formation of these identifications. The study finds that in spite of participants’ expressed preference for non-racialism, and despite their objections to rigid racial categories, in seeking to carve out alternative identities, they are participating in the boundary-making of which they are so critical.^

A Customer's Expectation and Perception of Hotel Service Quality in Cyprus

In recent years, hotels in Cyprus have encountered difficult economic times due to increasing customer demands and strong internal industry development competition. The hospitality industry’s main concern globally is to serve its customer S needs and desires, most of which are addressed through personal services. Hence, the hotel businesses that are able to provide quality services to its ever-demanding customers in a warm and efficient manner are those businesses which will be more likely to obtain a long term competitive advantage over their rivals. Ironically, the quality of services frequently cannot fully appreciated until something goes wrong, and then, the poor quality of services can have long lasting lingering effects on the customer base and, hence, often is translated into a loss of business. Nevertheless, since the issue of delivery of hospitality services always involves people, this issue must center around the management of the human resource factor, and in particular, on the way which interacts with itself and with guests, as service encounters. In the eyes of guests, hospitality businesses will be viewed successful or failure, depending on [he cumulative impact of the service encounters they have experienced on a personal level. Finally, since hotels are offering intangible and perishable personal service encounters, managing these services must be a paramount concern of any hotel business. As a preliminary exercise, visualize when you have last visited a hotel, or a restaurant, and then, ask yourself these questions: What did you feel about the quality of the experience? Was it a memorable one, which you would recommend it to others, or there were certain things, which could have made the difference? Thus, the way personalized services are provided can make the deference in attracting arid retaining long-term customers
