Laying Claim to Authenticity: Five Anthropological Dilemmas
No full textThe introduction to this special collection examines five dilemmas about
the use of the concept of authenticity in anthropological analysis. These
relate to 1) the expectation of a singular authenticity “deep” in oneself or
beyond the surface of social reality, 2) the contradictions emerging from
the opposition of authenticity with inauthenticity, 3) the irony of the notion
of invention of tradition (which deconstructs, but also offends), 4) the criteria
involved in the authentication of the age of objects (with a consideration
of their materiality), and 5) authenticity’s simultaneity, its contemporaneous
multiple conceptualizations in context. I argue for a perspective on the
study of authenticity that acknowledges the simultaneous co-existence of
more than one parallel manifestation of authenticity in any given negotiation

With or without gringos: When Panamanians talk about the United States and its citizens
No full textIn local and informal contexts, Panamanians talk about the power of the United States and describe its citizens in multifaceted and complex terms. In this article I examine those views as they are articulated in informal urban settings in Panama City and in conversa- tions with middle-class Panamanians. My respondents evaluate the US-Panama relationship and discuss individual North Americans with realism, reflecting a graceful but critical spirit of forgiveness toward their more powerful ally. A broader awareness of US colonialism in the past is combined with a pragmatic acknowledgement of opportunities in the present and the desire for a more equal relationship in the future. I argue that the opportunity to voice unreserved opinions about power- ful Others can potentially empower local actors

Great Expectations: Imagination and Anticipation in Tourism
No full textThe negotiation of expectations in tourism is a complex and dynamic process – one that is central to the imagination of cultural difference. Expectations not only affect the lives and experiences of tourists, but also their hosts, and play an important part in the success or failure of the overall tourism experience. It is for this reason, the authors argue, that special attention should be given to how expectations constitute and sustain tourism. The case studies presented here explore what fuels the desires to visit particular places, to what degree expectations inform the experience of the place, and the frequent disjunctions between tourist expectations and experiences. Careful attention is paid to how the imagination of the visitor inspires the imagination of the host, and vice-versa; how tourists and host communities actively imagine, re-imagine, and shape each other’s lives. This realization, has profound consequences, not solely for academic analysis, but for all those who participate in and work within the tourism industry

The REE potential in “urban” ore deposits: an evaluation on contents and prospecting tools from Italian municipal solid waste incinerators
No full textSolid residues from Municipal Solid Waste Incinerators (MSWI) may represent an
unconventional source of REE and other critical raw materials as defined by the European
Commission. In this contribution we present the total REE content in bottom and fly ashes,
which are the common MSWI outputs, and their estimated annual flow are significant.
Samples were digested with sodium peroxide sintering which is highly effective analytical
technique and the analysis was performed with ICP‐MS. Bottom and fly ashes have an average
concentration of 103 and 54 mg/kg ƩREY, respectively. For fly ashes the expected annual flow
is 1.1 t/a LREE and 0.3 t/a HREE, whereas for bottom ashes is 22.5 t/a LREE and 5.2 t/a HREE.
Moreover, we show that simple magnetic susceptibility measurements can be a promising
prospecting method when exploring for REE in urban ores is concerned

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
