A key feature of the luxury industry is its ability to sell dreams, such that consumers often refer to luxury products as desirable dream objects. This study aims to assess the empirical validity of this proposition. Does luxury actually fuel dreams? Because brands are manifestations of these dreams, this study examines if the dream value of an expansive set of brands relates directly to perceptions of them as luxury brands. More than 3,200 real luxury buyers, from six countries, participated in interviews about 60 luxury brands. The results reveal a strong correlation between luxury perceptions and the dream value of brands, across all countries. Yet, despite being categorised as luxury representatives though, many brands are not endowed with as much dream value as might be expected. Being perceived as a luxury product is not sufficient to evoke dreams and boost brand desirability. This is important for luxury brand management.
Successful implementation of national climate change agriculture adaptation policy in Vietnam requires rural communities to be able to respond to government programs. Critical players in ensuring this include provincial government officials and local farmers. Program success depends on strong uptake by farmers, which in turn depends on strong understanding of climate change and its agricultural and environmental impacts. Small-scale farming is dominant in Vietnam, and therefore the perceptions of such farmers regarding climate change and variability, necessary farming practice adjustment, and barriers to adaptation are important. However, there has been very little research devoted to understanding the factors that may influence farmers’ responses to climate change in Vietnam. The objectives of this paper are, therefore, to: (i) identify the of understanding and awareness of climate change among small-scale farmers in Vietnam, as it may affect their continuing practice as farmers; (ii) evaluate farmers’ understanding of adaptation to climate change; and (iii) record small-scale farmers’ responses to climate change adaptation, and therefore the capacity for rural communities to respond meaningfully to government climate change adaptation programs. Drawing on interviews of 172 small-scale farmers and six agricultural officers, we find that the majority of the farmers are, indeed, aware of local climate change. Both poor and non-poor farmers hold similar perceptions of changes in local climatic conditions. Importantly, however, these two groups differ significantly in terms of their perceptions and understandings of adaptation measures, barriers to adaptation, and factors influencing decisions. These differences reflect differences in income, financial capacity and education. Adaptation measures taken by poor farmers typically comprise relatively simple and minimal collective actions, and are typically low cost options. These are likely to have relatively low impacts in terms of their efficacy in responding to climate change. Non-poor farmers, on the other hand, tend to adopt more sophisticated responses, which require greater knowledge, skills and investment costs. These farmers are more likely to be able to respond to climate change with greater efficacy.
This paper describes a family of innovative fixed wing UAS with can vertical take off and land – the SONGBIRD family. With nominal payloads starting from 0.5 kg they can take off and land safely like a multi-rotor UAV, removing the need for an airstrip for the critical phases of operation. A specially designed flight controller allows stable flight at every point of the transition phase between VTOL and fixed wing mode. Because of this smooth process with a all time stable flight, very expensive payload like hyperspectral sensors or advanced optical cameras can be used. Due to their design all airplanes of the SONGBIRD family have excellent horizontal flight properties, a maximum speed of over 110 km/h, good gliding properties and long flight times of up to 1 h. Missions were flown in wind speeds up to 18 m/s. At every time of the flight it is possible to interrupt the mission and hover over a point of interest for detail investigations. The complete flight, including take-off and landing can be performed by autopilot. Designed for daily use in professional environments, SONGBIRDs are built out of glass-fibre and carbon composites for a long service life. For safe operations comprehensive security features are implemented, for example redundant flight controllers and sensors, advanced power management system and mature fail safe procedures. The aircraft can be dismantled into small parts for transportation. SONGBIRDS are available for different pay loads, from 500 g to 2 kg. The SONGBIRD family are interesting tools combining the advantages of multi-copter and fixed wing UAS.
