Turbulent Magnetic Reconnection in Two Dimensions
Two-dimensional numerical simulations of the effect of background turbulence
on 2D resistive magnetic reconnection are presented. For sufficiently small
values of the resistivity () and moderate values of the turbulent power
(), the reconnection rate is found to have a much weaker dependence
on than the Sweet-Parker scaling of and is even consistent
with an independent value. For a given value of , the dependence
of the reconnection rate on the turbulent power exhibits a critical threshold
in above which the reconnection rate is significantly enhanced.Comment: Accepted to MNRA
Free Floating Thrombus in Right Atrium and Pulmonary Thromboembolism
Os autores descrevem um caso de um doente
com uma neoplasia da bexiga inoperável,
internado por um quadro de síncope e
hipotensão arterial. Na avaliação do doente é
efectuado um ecocardiograma que mostra a
existência de um trombo livre ao nível das
cavidades direitas e dilatação das mesmas
que levou à hipótese diagnóstica de embolia
pulmonar. Perante a existência de uma
neoplasia com hemorragia recente, algumas
dúvidas terapêuticas surgiram, tendo sido
iniciado heparina. Devido a agravamento da
situação, com hipertensão pulmonar grave e
presença de volumosos trombos ao nível de
ambos os ramos da artéria pulmonar
visualizados por ecocardiografia
transesofágica, o doente acabou por ser
submetido a trombólise, embora com
algumas alterações ao esquema
habitualmente realizado. O doente melhorou,
sendo o ecocardiograma final normal
Encouraging the return to museums through the through enriching of the experience and the feeling of pride
The aim of the current study is to investigate the effect of museum experiences on visitors' willingness to recommend a museum and desire to return, based on the influence of the perception of coolness and the feeling of authentic pride. A sample of 308 usable questionnaires retrieved from four Lisbon (Portugal) museums provide a good understanding of the drivers of revisit and recommend intentions.
Museum Atmospheric Cues contribute to the perception of Museum Coolness and the feeling of Authentic Pride, which, in turn, have an effect on the intentions to Recommend and Revisit a museum. The perception of Museum Coolness has a stronger influence on both intentions to Revisit and Recommend.info:eu-repo/semantics/acceptedVersio
LOCAL COOPERATIVES' EVALUATION OF BUSINESS INVESTMENT OPPORTUNITIES
Agricultural cooperatives have been restructuring, by way of mergers, acquisitions, joint-ventures, and strategic alliances, to increase efficiencies to remain competitive in a changing business environment. The research evaluating the reorganization of cooperatives has revealed that less than one-half of the restructured businesses are financially successful. There is the potential to significantly influence the future health of the cooperative business sector if, first, insights can be gained concerning the factors being considered by cooperative managers when making restructuring decisions and, second, extension education programs can be adapted to meet the greatest need. In this study we examine: (a) what methods of valuation cooperatives are using when evaluating new business opportunities, and (b) what factors influence the methods of valuation preferred by cooperatives when evaluating new business opportunities.capital budgeting methods, cooperatives, finance, restructuring, Agribusiness,
Acculturation and overseas assignments: A review and research agenda
This review analyzes two streams of literature that are exploring a similar phenomenon from separate perspectives and only recently have they began to overlap; that of
migrant acculturation (from the psychology, sociology and anthropology research) and international assignee adjustment (from the international business research stream). We conducted a multiple correspondence analysis on a sample of 389 articles to provide the intellectual structure of the research in these fields. Our research indicates that: 1) the standard 2x2 matrix of acculturation is insufficient; 2) most past research focuses on USA to other countries and vice versa, suggesting there is much work left to explore other pairs of cultures ("there and back again" is not the same globally); 3) as global organizations are dominating the marketplace with many various staffing forms, variables such as corporate culture and management interaction will need to be incorporated; 4)
research needs to include dynamics over time as many individuals who have worked outside of their home country often become multi-cultural with a global mindset and the typical acculturation framework is insufficient; 5) past acculturation research focuses on the work or the
sociocultural context separately, while both need to be included; 6) and the extended family (parents, relatives, close friends, etc.) need to be considered
Are they sisters?: Using text mining approach to understand perceptions about Madeira and Bermuda
The current study explores how tourists perceive two islands with identical culture, but different demographic characteristics. Two complementary methodologies are employed: Netnography and Text Mining. Eight encodings are used based on the literature: Rating, Categories, Membership Level of reviewers, Language type, Tourism Experience Model, Content, and Symbology and Positive/Negative information. With the first methodology, all encodings are analyzed, while in the Text Mining, only three: TEM, ML and categories. Customer satisfaction is slightly superior in Madeira. Lifestyle and Leisure and Tourism, Travel and Commuting are the main themes. Reviewers are engaged with the destinations and the re-purchase scenario is highly probable
ARPES Study of the Metal-Insulator Transition in Bismuth Cobaltates
We present an angle-resolved photoemission spectroscopy (ARPES) study of a
Mott-Hubbard-type bismuth cobaltate system across a metal-insulator transition.
By varying the amount of Pb substitution, and by doping with Sr or Ba cation, a
range of insulating to metallic properties is obtained. We observe a systematic
change in the spectral weight of the coherent and incoherent parts, accompanied
by an energy shift of the incoherent part. The band dispersion also shows the
emergence of a weakly dispersing state at the Fermi energy with increasing
conductivity. These changes correspond with the changes in the
temperature-dependent resistivity behavior. We address the nature of the
coherent-incoherent parts in relation to the peak-dip-hump feature seen in
cuprates superconductors
