Internet-Based Delphi Administration: The Evolution of Methodological Best-Practices for Tourism Research

In the last 30 years, there has been increasing application of the Delphi technique in the tourism research domain and with it has come the identification of methodological advantages and disadvantages. With the recent availability of Internet-based research tools, the Internet has been identified as a means for mitigating Delphi disadvantages and maximizing advantages. The discourse, however, has been speculative in nature while the pragmatic analysis of Internet-based Delphi administration has been lean. Concomitantly, methodological guidance for the Internet-based Delphi architect is limited and best-practices have yet to emerge. Through critical examination, this paper seeks to advance understanding of the technique, to contribute to the evolution of Internet-based methodological best- practices, and to provide guidance for the Delphi architect. An Internet-based Delphi case study experience is reported and on this basis, a set of ten recommendations for tourism researchers are introduced for discussion

Pesquisa no lazer associada à internet: oportunidades e entraves

Since its earliest conception as a ‘galactic network’ of globally connected computers, the Internet has moved beyond the realm of science fiction to become the primary global communication medium and an increasingly popular research tool for scholars. In fact, some believe that the Internet has the potential to revolutionize research practice. Others, however, are skeptical of the Internet and its utility. Common concerns exist about the limited guidance available when using this ‘virtual research laboratory’. In the absence of enhanced understanding about the opportunities and constraints associated with Internet-based research, “it is likely that the resulting academic research will be flawed or compromised in some manner” (Roztocki, 2001: 1). Drawing on antecedent research and the researcher’s personal observations and experiences, this paper highlights some of the opportunities and constraints common to Internet-based research. It concludes with a set of recommendations for the judicial use of the Internet for leisure research.Desde a sua primeira conceituação como uma ‘rede galáctica’ de computadores globalmente interligados, a Internet passou de ficção científica à principal forma de comunicação global e tornou-se um portal de pesquisa acadêmica cada vez mais popular. De fato, há quem acredite que a Internet tem o potencial de revolucionar o ato de pesquisa. Todavia, outros encontram-se céticos em relação à sua utilidade neste respeito. Existem receios comuns sobre o apoio limitado enquanto à utilização deste ‘laboratório virtual de pesquisa’. Dada a falta de compreensão avançada sobre as oportunidades e os entraves associados com pesquisa baseada na Internet, “é provável que a pesquisa acadêmica resultante venha a ter falhas ou seja comprometida de alguma forma” (Roztocki, 2001: 1). Baseando-se em pesquisa anterior e nas experiências e observações da própria autora, este trabalho realça algumas das oportunidades e dos entraves comuns à pesquisa baseada na Internet. A conclusão avança várias sugestões para otimizar oportunidades e minimizar entraves relacionados especificamente com a pesquisa sobre o tema lazer

Do Cultural Differences Influence Tourists’ Likelihood to Seek Information Via Social Media in the Event of a Crisis?

This study examined the influence of the cultural backgrounds of international travelers on the likelihood to turn to social media to seek information if a crisis were to occur while traveling. Data for this study were generated by surveys from an online panel of international respondents from South Korea, China, India, Australia, and Brazil. A total of 2,416 completed surveys were used. The results indicated that travelers from different countries varied in their likelihood to seek information via social media during a crisis. Tourists from South Korea were found to be the most likely to access social media to find information about a crisis while traveling. The different cultures also had different preferred sources for seeking information during a crisis. This study demonstrated the significance of examining the influence of characteristics on the potential use of social media during a crisis. Implications and recommendations are presented

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

Measurement of the ratios of branching fractions R(D∗)\mathcal{R}(D^{*}) and R(D0)\mathcal{R}(D^{0})

The ratios of branching fractions $\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu})$ and $\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu})$ are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb${ }^{-1}$ of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode $\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}$. The measured values are $\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024$ and $\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066$, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is $\rho=-0.43$. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages
