What’s past is prologue: history, current status and future prospects of library development in Bhutan

Purpose This paper aims to outline the history of libraries in Bhutan, to describe the current state of library development and to recommend priority areas for library enhancement. Design/methodology/approach The authors have worked extensively as library professionals in Bhutan and share factual details derived from their personal experience. They review the published literature, particularly the fieldwork of two scholars who studied Bhutan’s libraries and library workers. The authors use their own experience to interpret those findings and make suggestions for future development. Findings The paper briefly traces the evolution of print culture and the history of libraries, exploring monastic, school, college, public and national libraries. The paper examines government policies regarding education and libraries and discusses the acknowledgment of the value of libraries and the lack of actual support. Originality/value There is limited study of the history of reading culture or libraries in Bhutan. The authors document their first-hand experiences and efforts to implement systems for library resource sharing and professional development. The authors hope that this record will serve to illuminate past effort, to describe the unique information environment in Bhutan and to guide future decision-making. The authors recommend many future avenues for study, including reading habits, information-seeking behavior and attitudes toward libraries and librarians

Manager\u27s Perspectives on the Provision of Healthy Meals in Resort Hotels

This research aimed to understand hotel managers’ attitudes toward the provision of healthy meals. The study deployed a mailing survey to assess the managers’ perceptions. A closed-ended questionnaire was developed evaluating the role of healthy food choices in Mediterranean resort hotels. The findings showed that (1) atmosphere in the restaurant, (2) appealing display of food, and (3) eating habits and lifestyle were more important than personal health when selecting a meal. In addition, this study suggested that the managers were not ready to promote healthy eating because their customers would have been critical of this new service concep

Factors influencing healthy meal choice in Germany

The aim of this study is to discover what German restaurant customers consider to be healthy. Owing to the paucity of literature on healthy meals, this research attempts to initiate an exploratory investigation testing a new psychological construct of health meals by using college students as the study population. The proposed scale consists of three dimensions (nutrition value, organic content, and gastronomy), which are defined by 16 attributes. This study finds that low in fat is the major consideration for selecting healthy meals, whereas the aroma of meals is not a concern for healthy meal choice. In the final analysis 15 indicators are retained in the measurement scale after the reliability test. Since the dimension of organic content has the highest reliability score, it could be best utilized as the surrogate indicator assessing the perception of a healthy meal. The derived scale is rather embryonic since it is tested only on German students. It is suggested that the scale should be further tested by drawing large samples from heterogeneous populations to boost the scale\u27s construct validity so as to collect samples from restaurant goers with different cultural background

A transmission electron microscope study of N\'eel skyrmion magnetic textures in multilayer thin film systems with large interfacial chiral interaction

Skyrmions in ultrathin ferromagnetic metal (FM)/heavy metal (HM) multilayer systems produced by conventional sputtering methods have recently generated huge interest due to their applications in the field of spintronics. The sandwich structure with two correctly-chosen heavy metal layers provides an additive interfacial exchange interaction which promotes domain wall or skyrmion spin textures that are N\'eel in character and with a fixed chirality. Lorentz transmission electron microscopy (TEM) is a high resolution method ideally suited to quantitatively image such chiral magnetic configurations. When allied with physical and chemical TEM analysis of both planar and cross-sectional samples, key length scales such as grain size and the chiral variation of the magnetisation variation have been identified and measured. We present data showing the importance of the grain size (mostly < 10nm) measured from direct imaging and its potential role in describing observed behaviour of isolated skyrmions (diameter < 100nm). In the latter the region in which the magnetization rotates is measured to be around 30 nm. Such quantitative information on the multiscale magnetisation variations in the system is key to understanding and exploiting the behaviour of skyrmions for future device applications.Comment: 11 pages , 6 figures, journal articl

Atmospheric nitrogen oxides (NO and NO2) at Dome C, East Antarctica, during the OPALE campaign

Mixing ratios of the atmospheric nitrogen oxides NO and NO2 were measured as part of the OPALE (Oxidant Production in Antarctic Lands & Export) campaign at Dome C, East Antarctica (75.1 degrees S, 123.3 degrees E, 3233 m), during December 2011 to January 2012. Profiles of NOx mixing ratios of the lower 100m of the atmosphere confirm that, in contrast to the South Pole, air chemistry at Dome C is strongly influenced by large diurnal cycles in solar irradiance and a sudden collapse of the atmospheric boundary layer in the early evening. Depth profiles of mixing ratios in firn air suggest that the upper snowpack at Dome C holds a significant reservoir of photolytically produced NO2 and is a sink of gas-phase ozone (O-3). First-time observations of bromine oxide (BrO) at Dome C show that mixing ratios of BrO near the ground are low, certainly less than 5 pptv, with higher levels in the free troposphere. Assuming steady state, observed mixing ratios of BrO and RO2 radicals are too low to explain the large NO2 : NO ratios found in ambient air, possibly indicating the existence of an unknown process contributing to the atmospheric chemistry of reactive nitrogen above the Antarctic Plateau. During 2011-2012, NOx mixing ratios and flux were larger than in 2009-2010, consistent with also larger surface O-3 mixing ratios resulting from increased net O-3 production. Large NOx mixing ratios at Dome C arise from a combination of continuous sunlight, shallow mixing height and significant NOx emissions by surface snow (F-NOx). During 23 December 2011-12 January 2012, median F-NOx was twice that during the same period in 20092010 due to significantly larger atmospheric turbulence and a slightly stronger snowpack source. A tripling of F-NOx in December 2011 was largely due to changes in snowpack source strength caused primarily by changes in NO3- concentrations in the snow skin layer, and only to a secondary order by decrease of total column O-3 and associated increase in NO3- photolysis rates. A source of uncertainty in model estimates of F-NOx is the quantum yield of NO3- photolysis in natural snow, which may change over time as the snow ages

Inhomogeneous losses and complexness of wave functions in chaotic cavities

In a two-dimensional microwave chaotic cavity Ohmic losses located at the contour of the cavity result in different broadenings of different modes. We provide an analytic description and establish the link between such an inhomogeneous damping and the complex (non-real) character of biorthogonal wave functions. This substantiates the corresponding recent experimental findings of Barthélemy et al. (Europhys. Lett., 70 (2005) 162)
