A recent paper by Kirkland on nonlinear electron image processing, referring to a relatively new textbook, highlights the persistence in the literature of calculations based on incomplete and/or incorrect models of electron imageing, notwithstanding the various papers which have recently pointed out the correct forms of the appropriate equations. Since at least part of the problem can be traced to underlying assumptions about the illumination coherence conditions, we attempt to clarify both the assumptions and the corresponding equations in this paper, illustrating the effects of an incorrect theory by means of images calculated in different ways.The first point to be made clear concerning the illumination coherence conditions is that (except for very thin specimens) it is insufficient simply to know the source profiles present, i.e. the ranges of different directions and energies (focus levels) present in the source; we must also know in general whether the various illumination components are coherent or incoherent with respect to one another.

Since phase contrasts of STEM images, that is, Fresnel diffraction fringes or lattice images, manifest themselves in field emission scanning microscopy, the mechanism for image formation in the STEM mode has been investigated and compared with that in CTEM mode, resulting in the theory of reciprocity. It reveals that contrast in STEM images exhibits the same properties as contrast in CTEM images. However, it appears that the validity of the reciprocity theory, especially on the details of phase contrast, has not yet been fully proven by the experiments. In this work, we shall investigate the phase contrast images obtained in both the STEM and CTEM modes of a field emission microscope (100kV), and evaluate the validity of the reciprocity theory by comparing the experimental results.

The primary focus in our laboratory is the study of higher order chromatin structure using three dimensional electron microscope tomography. Three dimensional tomography involves the deconstruction of an object by combining multiple projection views of the object at different tilt angles, image intensities are not always accurate representations of the projected object mass density, due to the effects of electron-specimen interactions and microscope lens aberrations. Therefore, an understanding of the mechanism of image formation is important for interpreting the images. The image formation for thick biological specimens has been analyzed by using both energy filtering and Ewald sphere constructions. Surprisingly, there is a significant amount of coherent transfer for our thick specimens. The relative amount of coherent transfer is correlated with the relative proportion of elastically scattered electrons using electron energy loss spectoscopy and imaging techniques.Electron-specimen interactions include single and multiple, elastic and inelastic scattering. Multiple and inelastic scattering events give rise to nonlinear imaging effects which complicates the interpretation of collected images.

Food and gastronomic values of a country are distinguished assets in marketing places. The aim of this article is exploring the ways in which Serbia rebrands itself through promoting the local food and culture and positions the nation brand in a transnational marketing context. The key concepts for this research originate from the literature in place marketing and branding. The gastronomic offer is an instrument shaping people’s perceptions about Serbia that is represented and communicated through values, narratives and manifestations. Accordingly, semiotics is adopted for analysing the data, which builds on three levels: axiological, narrative and discursive. Content analysis is used as a supportive method to infer meanings from codes and to determine emerging themes overarching the units of meaning.  The tourism marketing strategy of The National Tourism Organization of Serbia (TOS) is closely examined through the touristic promotion materials (i.e. catalogues, posters, Soul Food video). In sum, the analysis results reveal how the country branding strategy of Serbia is handled in terms of the impact on the perceptions with a focus on food as a tourist attraction. The research is valuable for place-marketers, strategists, governments, and scholars from different fields of academia.

Penelitian ini adalah sebuah usaha yang dilakukan untuk mengurai masalah yang dihadapi para stakeholder dalam mewujudkan sebuah pengelolaan pariwisata yang berkelanjutan di kawasan Danau Toba. Indikator yang diukur dalam penelitian ini adalah indikator dasar dari 5 (lima) isu utama pengembangan periwisata berkelanjutan yang telah dikembangkan oleh United Nation World Tourism Organization (UNWTO). Penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif dan diperkuat dengan data-data yang bersifat kuantitatif. Berdasarkan hasil pengukuran indikator-indikator dasar tersebut dan pendalaman yang dilakukan dengan diskusi-diskusi yang dilakukan dengan para informan penelitian, diketahui bahwa sebenarnya penyelesaian persoalan dasar pengembangan pariwisata berkelanjutan di sebuah destinasi wisata masih menjadi tugas besar bagi para stakeholder kepariwisataan di kawasan tersebut. Berdasarkan jenis permasalahan yang ada, maka terdapat kebutuhan kebijakan pengembangan terkait: 1) peningkatkan perekonomian dengan adanya kegiatan pariwisata; 2) penjaminan kesejahteraan daerah dan masyarakat lokal dengan adanya kegiatan pariwisata; 3) pemenuhan kepuasan pengunjung; 4) pelibatan masyarakat lokal di dalam pengelolaan kepariwisataan; dan 5) penjaminan kelestarian lingkungan hidup.   Kata kunci: pengembangan, pariwisata berkelanjutan, Danau Toba

AbstractBeginning with the establishment of a Supreme Commission for Tourism and Antiquities’ (SCTA) in 2000, there have been official attempts by the government of Saudi Arabia to encourage domestic tourism in order to tap into the huge amounts that Saudis spend annually on vacations. This paper examines the motivations and attitudes of consumers toward tourism destinations and activities within the country (domestic tourism). Using data collected through a structured self-administered questionnaire, the study finds that familiarity and trust of the local environment, perceptions of the safer domestic environment, and limitations imposed by respondents’ vacation timing are the primary motives for choosing to spend their vacations locally, while lack of quality domestic tourist sites and services (including entertainment facilities), lack of tourism information, insufficient tourism organization services, and the harsh local environmental conditions during summer are factors that ‘push’ people from spending the vacations locally. Attitudes toward domestic tourism are generally negative, although there are significant differences in attitudes between respondents who prefer domestic destinations and those who prefer to travel out of Kingdom. Implications of the findings are outlined and discussed.
