Going back to its roots: can hospitableness provide hotels competitive advantage over the sharing economy?

While the customer experience is at the heart of the hospitality industry, experience-related research remains underrepresented. This gap is critical, particularly given the emerging threat of the sharing economy to the hotel industry along experiential factors. Using data from a survey of 630 customers who stayed at a hotel or an Airbnb, the authors use structural equation modeling to compare two models with alternative conceptualizations of the dynamics of experiential consumption in the accommodations industry. Building on the concept of the experiencescape from the branding and hospitality and tourism literatures, the model enhances Pine and Gilmore’s (1998) original experience economy construct by demonstrating the critical role of the dimension of hospitableness in facilitating favorable experiential and brand-related outcomes, particularly in the context of the hotel experience. The findings have important implications for the hotel industry’s strategic experience design initiatives and emphasize the need to use hospitableness in order to create a competitive advantage in a rapidly changing environment.Accepted manuscrip

Improving package recommendations through query relaxation

Recommendation systems aim to identify items that are likely to be of interest to users. In many cases, users are interested in package recommendations as collections of items. For example, a dietitian may wish to derive a dietary plan as a collection of recipes that is nutritionally balanced, and a travel agent may want to produce a vacation package as a coordinated collection of travel and hotel reservations. Recent work has explored extending recommendation systems to support packages of items. These systems need to solve complex combinatorial problems, enforcing various properties and constraints defined on sets of items. Introducing constraints on packages makes recommendation queries harder to evaluate, but also harder to express: Queries that are under-specified produce too many answers, whereas queries that are over-specified frequently miss interesting solutions. In this paper, we study query relaxation techniques that target package recommendation systems. Our work offers three key insights: First, even when the original query result is not empty, relaxing constraints can produce preferable solutions. Second, a solution due to relaxation can only be preferred if it improves some property specified by the query. Third, relaxation should not treat all constraints as equals: some constraints are more important to the users than others. Our contributions are threefold: (a) we define the problem of deriving package recommendations through query relaxation, (b) we design and experimentally evaluate heuristics that relax query constraints to derive interesting packages, and (c) we present a crowd study that evaluates the sensitivity of real users to different kinds of constraints and demonstrates that query relaxation is a powerful tool in diversifying package recommendations

No. 27: Food Security in Africa\u27s Secondary Cities: No. 1 Mzuzu, Malawi

This report marks the first stage of AFSUN’s goal of expanding knowledge about urban food systems and experiences of household food insecurity in secondary African cities. It contributes to an understanding of poverty and sustainability in Mzuzu, Malawi, through the lens of household food security. The focus on food as an urban issue not only speaks to the development challenges presented by urbanization, but it also brings a fresh perspective to debates about food security in Malawi. The urban setting highlights the changing food system in Malawi where people in rural and urban areas are increasingly reliant on cash income to buy food. The report’s key findings include that the most vulnerable households are those without a formal wage income, households headed by older people, especially older women, and households that are not able to produce food in the rural areas. The research also shows that the food system is dynamic and diverse, with households accessing food from a variety of formal and informal food sources and relying on rural-urban linkages for urban survival. Urban and rural agriculture are important features of the food system, but there is little evidence that these are the “self-help” responses to poverty that advocates for urban agriculture in Africa sometimes imply

Improving aquaculture feed in Bangladesh: From feed ingredients to farmer profit to safe consumption

Use of manufactured feeds in aquaculture in Bangladesh has grown rapidly over the last five years. More than 1 million tonnes of commercially formulated feeds and 0.3-0.4 million tonnes of farm-made feeds were produced in 2012, and sectoral growth is projected to increase substantially over the medium term. This working paper summarizes findings from a study, conducted as part of the WorldFish/USAID “Feed the Future-Aquaculture” project in 2012, assessing the current status of the aquaculture feed sector in Bangladesh. Fish feed value chains, market trends, ingredients and formulation systems, farm feeding practices, ancillary services and feed regulations were investigated. The study identifies a number of entry points for interventions in the sector, and investments which would improve feed quality and farmer access to better feeds and support the growth of sustainable aquaculture
