Israeli and Palestinian Archaeological Inventories, GIS and Conflicting Cultures in the Occupied West Bank
Effective protection and management of cultural heritage resources in a specific region requires planning strategies and policies, which rely on the sum of existing information about archaeology and cultural heritage. The role of archaeological inventories in the process of heritage management is, therefore, central and critical, as they are supposed to convey our present state of knowledge and be the basis on which management priorities are decided. This dissertation examines existing Israeli and Palestinian archaeological and architectural inventories covering the occupied West Bank, as well as assessing the role of Geographic Information Systems for heritage management in this region. Its main objectives are twofold: first, it explores the nature of archaeological records and the way they reflect particular research interests and heritage management priorities; and second, it examines variability in data quality, coverage, accuracy and reliability. By examining recording emphasis in West Bank inventories, this research interrogates the ways in which social, political, ideological or cultural values may affect different aspects of data collection and management. The assessment of different inventories through comparison, analysis and fieldwork, sheds light on current Israeli and Palestinian approaches to documentation and data management, as well as broader issues associated with the collection and use of information about the past in contexts of cultural conflict. Framed within the political context of the Israeli-Palestinian conflict, this research has theoretical considerations and practical implications. On the theoretical side, it raises awareness of personal, academic and national interests, the ways they are manifested in archaeological inventories, and the means by which they dictate the process of cultural knowledge production. On the practical side, it provides a set of recommendations for ways to improve current data management and dissemination strategies, and thereby encourage more efficient decision-making processes and better protection and preservation of heritage sites in the West Bank
Selective Perchlorate Sensing Using Electrochemical Impedance Spectroscopy with Self-Assembled Monolayers of semiaza-Bambusurils
In the last two decades, perchlorate salts have been identified as environmental pollutants and recognized as potential substances affecting human health. We describe self-assembled monolayers (SAMs) of novel semiaza-bambus[6]urils (semiaza-BUs) equipped with thioethers or disulfide (dithiolane) functionalities as surface-anchoring groups on gold electrodes. Cyclic voltammetry (CV) with Fe(CN)63â/4â as a redox probe, together with X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and ellipsometry, were employed to characterize the interactions at the interface between the anchoring groups and the metal substrate. Data showed that the anion receptorsⲠpacking on the gold strongly depends on the anchoring group. As a result, SAMs of BUs with lipoic amide side chains show a concentration-dependent layer thickness. The BU SAMs are extremely stable on repeated electrochemical potential scans and can selectively recognize perchlorate anions. Our electrochemical impedance spectroscopy (EIS) studies indicated that semiaza-BU equipped with the lipoic amide side chains binds perchlorate (2â100 mM) preferentially over other anions such as Fâ, Clâ, Iâ, AcOâ, H2PO4â, HPO42â, SO42â, NO2â, NO3â, or CO32â. The resistance performance is 10 to 100 times more efficient than SAMs containing all other tested anions.</p
Status pivoting
Prior research has established that status threat leads consumers to display status-related products such as luxury brands. While compensatory consumption within the domain of the status threat (e.g., products associated with financial and professional success) is the most straightforward way to cope with comparisons to high-status individuals, we examine when, why, and how consumers cope with status threat by choosing to âpivotâ and display success and achievements in alternative domains. Using a mixed-method approach combining field and lab experiments, incentive-compatible designs, netnographic analysis, observational study, and qualitative interviews, we show that consumers cope with status threat by signaling their status and success in alternative domains. We conceptualize this behavior as âstatus pivotingâ and show that it occurs because experiencing status threat motivates consumers to adopt beliefs about trade-offs across domains; that is, to believe that status acquisition requires trade-offs and hence othersâ success in one domain comes at the cost of success in another domain. We compare the prevalence and appeal of status pivoting to restoring status within the domain of the threat. We further examine when consumers are likely to engage in status pivoting and show that this effect is attenuated when high status within the domain of the threat is attainable
Historizing the present: Research agenda and implications for consumer behavior
This paper conceptualizes the phenomenon of historizing the present, defined as emphasizing the historical significance of present events and treating the present from the perspective of history. The authors identify four modes of historizing the present (emphasizing that: (1) the present will shape history; (2) the present is a unique moment in history; (3) the present will be remembered in history; (4) the present echoes history) and demonstrate how historizing can be employed by marketers of forâprofit and nonprofit organizations in a variety of contexts. The paper examines the psychological implications of appreciating the historical significance of the present and outlines a research agenda for studying the downstream behavioral consequences of historizing the present across diverse substantive consumer domains. It concludes with an examination of the broader societal implications of historizing the present as well as its implications for consumer wellâbeing
Crowd- and Community-fuelled Archaeological Research. Early Results from the MicroPasts Project
The MicroPasts project is a novel experiment in the use of crowd-based methodologies to enable participatory
archaeological research. Building on a long tradition of offline community archaeology in the UK, this initiative aims to
integrate crowd-sourcing, crowd-funding and forum-based discussion to encourage groups of academics and volunteers
to collaborate on the web. This paper will introduce MicroPasts, its aims, methods and initial results, with a particular
emphasis on project evaluation. The evaluative work conducted over the first few months of the project already
demonstrates the potential for crowd-sourced archaeological 3D modelling, especially amongst younger audiences,
next to more traditional kinds of crowd-sourcing such as transcription. It has also allowed a comparative assessment
of different methods for sustaining contributor participation through time and a discussion of their implications for
the sustainability of the MicroPasts project and (potentially) other archaeological crowd-sourcing endeavours
IgG Serum Antibodies to Shigella sonnei Lipopolysaccharide Are Inversely Associated with the Incidence of Culture-Proven S. sonnei Shigellosis in Israeli Children and Adolescents
Background: Shigella is a leading cause of moderate-to-severe diarrhea globally, with young children most affected. The burden of shigellosis drops increasingly with age, inferring the acquisition of natural immunity. We tested the hypothesis that IgG antibodies elicited against Shigella O-specific polysaccharide (O-SP) are correlates of age-acquired immunity. Objectives: We examined levels and determinants of serum IgG to S. sonnei LPS and the association with the incidence of S. sonnei shigellosis in Israeli children and adolescents. Methods: We analyzed 1096 serum samples from 0- to 19-year-olds collected in 2008â2015 for IgG anti-S. sonnei LPS levels by ELISA. Corresponding age-specific incidences of culture-proven S. sonnei shigellosis from 2008 to 2015 were obtained. We compared ecologically IgG levels, prevalence above a proposed protective threshold, and S. sonnei shigellosis incidence. Results: In a multivariable analysis model, children aged 1â4, 5â14, and 15â19 years were 6.71, 27.68, and 48.62 times more likely to have IgG anti-S. sonnei LPS above the threshold than those aged < 1 year, respectively (p < 0.001). Infants 0â3 months old had relatively high IgG anti-S. sonnei LPS levels of maternal origin that dropped thereafter. Children of low socioeconomic status had a 2.73 times higher likelihood of having IgG anti-S. sonnei LPS above the threshold (p < 0.001). A significant inverse correlation between age-specific IgG anti-S. sonnei LPS levels and S. sonnei shigellosis incidence was observed (Spearman rho= â0.76, p = 0.028). Conclusions: The study results support anti-S. sonnei LPS antibodies as correlates of protection that can inform Shigella vaccine development
Participation in heritage crowdsourcing
This paper draws upon the experience of several years of running a multi-application crowdsourcing platform, as well as a longitudinal evaluation of participant profiles, motivations and behaviour, to argue that heritage crowdsourcing cannot straightforwardly be considered a democratising form of cultural participation. While we agree that crowdsourcing helps expand public engagement with state-funded activities at Galleries, Libraries, Archives, and Museums, we also note that, the involved public cohort is not radically different in socio-demographic make-up to the one that physically visits such institutions, being for example financially better-off with high levels of formal education. In shedding light on issues of participation and cultural citizenship, through a both theoretically and empirically rich discussion, this paper casts light on the current impact of heritage crowdsourcing, in terms of both its strengths and weaknesses. The study will also be useful for cultural heritage policy and practice, museum management and curatorship to potentially guide the choices and strategies of funders and organisations alike
Now or never: perceptions of uniqueness induce acceptance of price increases for experiences more than for objects
Seven studies test and support the prediction that consumers are more willing to accept a price increase for an experiential versus a material purchase; an effect explained by the greater uniqueness of experiences. Critically, the uniqueness model advanced here is found to be independent of the happiness consumers derive from the purchase. To gain a deeper understanding of the uniqueness mechanism, this investigation then advances and tests a four-facet framework of uniqueness (unique opportunity, unique purchase, unique identity, and counterconformity). Together, the findings converge on the conclusion that consumers perceive the opportunity to have a particular experience (vs. object) as more unique, and this unique opportunity increases their willingness to accept a price increase. Overall, this work extends the experiential versus material purchases literature into a new domainâthat of pricing; identifies the dimensionâuniquenessâand its precise facet responsible for the effectâunique opportunity; and demonstrates that this model unfolds in a pattern distinct from the oft researched model centered on consumer happiness. Theoretical and practical implications are discussed.info:eu-repo/semantics/acceptedVersio
