回望“真实性”(authenticity)(上)——一个旅游研究的热点

麦坎内尔(MacCannell)掀起的"真实性"研究热已逾30年,其间,研究视角逐渐从"客观"转向"主观"。这既反映出真实性内涵的延展与变迁,亦凸显旅游主体—游客体验的重要性。然而,就研究者日渐褊狭的视域来看,旅游客体真实性对旅游体验真实性的影响从松散到几近断裂,旅游主体甚至以"悦纳万物"的信仰姿态视一切"存在"为真,从而收获真实的体验。客观真实与主观真实,究竟是谁决定或影响了谁?对此问题的探寻导致学界对旅游客体之"虚假"的重新界定和对旅游体验之"真实"的再度好奇,并因此形成旅游真实性研究的纷争局面。有鉴于此,对国内外真实性研究做一番缘起、视角、界定等方面的梳理和反思,或将对国内相关研究与应用有所裨益。

Authenticity Protection of Agricultural Landscapes in Rural Tourism Development

With the rapid development of the economy, people’s living standards have been improved constantly. As people’s material life has been gradually improved, people pay more attention to the pursuit of high-quality spiritual life, and the flourishing development of rural tourism just meets people’s pursuit about returning to nature that is far away from the hustle and bustle of the city, and about experiencing funny and quiet life in the countryside. The development of rural tourism relies on agricultural landscape resources, and the correct understanding and protection of the original value of agricultural landscape resources can effectively ensure the sustainable use of agricultural landscape resources. If land for agricultural landscape resource is occupied for developing blindly without reasonable planning and construction, it will lead to the distortion of the authentic value of agricultural landscape, which in turn affects the sustainable development of rural tourism.

Feasibility Study for Applying Spectral Imaging for Wheat Grain Authenticity Testing in Pasta

Authentication of pasta is currently determined using molecular biology-based techniques focusing on DNA as the target analyte. Whilst proven to be effective, these approaches can be criticised as being destructive, time consuming, and requiring specialist instrument training. Advances in the field of multispectral imaging (MSI) and hyperspectral imaging (HSI) have facilitated the development of compact imaging platforms with the capability to rapidly differentiate a range of materials (inclusive of grains and seeds) based on surface colour, texture and chemical composition. This preliminary investigation evaluated the applicability of spectral imaging for identification and quantitation of durum wheat grain samples in relation to pasta authenticity. MSI and HSI were capable of rapidly distinguishing between durum wheat and adulterant common wheat cultivars and assigning percentage adulteration levels characterised by low biases and good repeatability estimates. The results demonstrated the potential for spectral imaging based seed/grain adulteration testing to augment existing standard molecular approaches for food authenticity testing.

Distance decay of place attachment and perceived authenticity of mountain tourism destinations in China

Place attachment has been a research focus in the fields of park and recreation management.Place attachment plays an important role in promoting sustainable development of parks and mountain tourism destination,however,there are limited studies that identified the spatial patterns of place attachment,especially in the context of mountain tourism destinations in China.Also,the geospatial spectrum of visitors is usually broad,examining the multivariate relationships among spatial proximity,perceived authenticity,and place attachment are essential for mountain tourism destinations to promote destination image and strengthen emotional bonding with targeted visitor groups.In this study,we selected an iconic and highly visited park,Jiuzhai Valley National Park in China,as our study site and conducted an on-site visitor survey to collect 557 samples.Study uses factor analysis and the structure equation model to analyze the relationship among spatial proximity,perceived authenticity,and place attachment.Results validate the two-dimension structure of place attachment and perceived authenticity.Study findings suggest that spatial proximity has significant impacts on existential authenticity and place identity,but has no significant impacts on place dependence.Perceived authenticity has a positive impact on place attachment.Study results advance the theories of place attachment and provide effective strategies to enhance emotional attachment between visitors and mountain tourism destinations.

Geographical authenticity evaluation of Mentha haplocalyx by LIBS coupled with multivariate analyzes

Mentha haplocalyx(mint)is a significant traditional Chinese medicine(TCM)listed in the Catalogue of’Medicinal and Food Homology’,therefore,its geographical origins(GOs)are critical to the medicinal and food value.Laser-induced breakdown spectroscopy(LIBS)is an advanced analytical technique for GOs certification,due to the fast multi-elemental analysis requiring minimal sample pretreatment.In this study,LIBS data of sampled mint from five GOs were investigated by LIBS coupled with multivariate statistical analyzes.The spectral data was analyzed by two chemometric algorithms,i.e.principal component analysis(PCA)and least squares support vector machines(LS-SVM).Specifically,the performance of LS-SVM with least kernel and radial basis function(RBF)kernel was explored in sensitivity and robustness tests.Both LS-SVM algorithms exhibited excellent performance of classification in sensitive test and good performance(a little inferior)in robustness test.Generally,LS-SVM with linear kernel equally outperformed LS-SVM based on RBF kernel.The result indicated the potential for future applications in herbs and food,especially for in situ GOs applications of TCM authenticity rapidly.

Studies on the Authenticity of Local Wines by Spectroscopic and Chemometric Analysis

The authenticity of 91 wines produced in Cyprus from both indigenous and other vine varieties were investigated by a holistic approach, using, advanced technology such as SNIF-NMR （site-specific natural isotopic fractionation-nuclear magnetic resonance） and 1R-MS （isotope ratio-mass spectrometry） for the determination of the stable isotopes and ICP （inductively coupled plasma spectroscopy） for some heavy metals. The spectroscopic characteristics were evaluated statistically using different chemometric methods. The dependency of the D/H （deuterium/hydrogen） ratio of the methylene site in the ethanol molecule （D/H）ll and also theδ ^18O values of the wine water, were the most useful discriminators. Isotopic results allow us to have a complete idea about the regional variability of the isotopes. Among the metals, Ni followed by Pb was the ones with the highest discrimination value. The determined concentrations of Pb, Ni, Cr and Cd that are related to the safety of wines were within the acceptable limits that have been established by the OIV （international organization of vine and wine） or comparable with the results of the wines of other European countries. The study of the correlation between the load of heavy metals and isotopes in wines showed a dependence on the grape variety but not the geographical location of the vineyard. This is probably due to the close proximity of wine regions in Cyprus.

Ensuring the Authenticity and Non-Misuse of Data Evidence in Digital Forensics

In forensic investigations,it is vital that the authenticity of digital evidence should be ensured. In addition,technical means should be provided to ensure that digital evidence collected cannot be misused for the purpose of perjury. In this paper,we present a method to ensure both authenticity and non-misuse of data extracted from wireless mobile devices. In the method,the device ID and a timestamp become a part of the original data and the Hash function is used to bind the data together. Encryption is applied to the data,which includes the digital evidence,the device ID and the timestamp. Both symmetric and asymmetric encryption systems are employed in the proposed method where a random session key is used to encrypt the data while the public key of the forensic server is used to encrypt the session key to ensure security and efficiency. With the several security mechanisms that we show are supported or can be implemented in wireless mobile devices such as the Android,we can ensure the authenticity and non-misuse of data evidence in digital forensics.
