Research Analysis

This editorial is the first of a two-part critical reflection upon the progress of Hospitality & Society in its first ten years in relation to the original aims and ambitions. Drawing primarily upon the Dimensions database, a field of research analysis indicates the journal achieving multidisciplinary coverage through its publications with the four most popular fields being: studies in human society; sociology; commerce, management, tourism and services; business and management. The wide range of authors’ disciplines and subjects suggests the metaphor of hospitality is mobilizing meanings across disciplines, geographies and sectors of hospitality studies. Academic journals and books publishing papers citing articles from Hospitality & Society further reflect the breadth of the journal’s impact and reach and the relevance of hospitality to many aspects of society. Evolution of the journal is considered in relation to the editorial team’s structure as well as that of the editorial and advisory boards’ composition, acknowledging implications for the types of knowledge generated. The goal of inclusivity is considered in relation to language and contributing authors’ geographical distribution. An interdisciplinary turn in hospitality studies is noted. Key steps in the journal’s development are noted in relation to sponsorship, journal quality grading and its implications, as well as the importance of the publisher’s values. The editors give thanks to all those involved.

A complex system is a system involving particles whose pairwise interactions cannot be composed in the same way as in classical Mechanics, i.e., the result of interaction of each particle with all the remaining ones cannot be expressed as a sum of its interactions with each of them (we cannot even know the functional dependence of the total interaction on the single interactions). Moreover, in view of the wide range of its applications to biologic, social, and economic problems, the variables describing the state of the system (i.e., the states of all of its particles) are not always (only) the usual mechanical variables (position and velocity), but (also) many additional variables describing e.g., health, wealth, social condition, social rôle ⋯, and so on. Thus, in order to achieve a mathematical description of the problems of everyday’s life of any human society, either at a microscopic or at a macroscpoic scale, a new mathematical theory (or, more precisely, a scheme of mathematical models), called KTAP, has been devised, which provides an equation which is a generalized version of the Boltzmann equation, to describe in terms of probability distributions the evolution of a non-mechanical complex system. In connection with applications, the classical problems about existence, uniqueness, continuous dependence, and stability of its solutions turn out to be particularly relevant. As far as we are aware, however, the problem of continuous dependence and stability of solutions with respect to perturbations of the parameters expressing the interaction rates of particles and the transition probability densities (see Section The Basic Equations has not been tackled yet). Accordingly, the present paper aims to give some initial results concerning these two basic problems. In particular, Theorem 2 reveals to be stable with respect to small perturbations of parameters, and, as far as instability of solutions with respect to perturbations of parameters is concerned, Theorem 3 shows that solutions are unstable with respect to “large” perturbations of interaction rates; these hints are illustrated by numerical simulations that point out how much solutions corresponding to different values of parameters stay away from each other as t→+∞.

Abstract A description is provided for Ustilago hypodytes. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A wide range of grasses, including species of Agropyron (many), Ammophila, Brachypodium, Bromus, Calamagrostis, Diplachne, Distichlis, Elymus (many), Festuca, Glyceria, Hilaria, Hordeum, Haynaldia, Lygeum, Melica, Orysopsis, Panicum, Phalaris, Phleum, Poa (many), Puccinellia, Secale, Sitanion, Sporobolus, Stipa (many), and Trisetum. DISEASE: Stem smut of grasses. GEOGRAPHICAL DISTRIBUTION: Chiefly a temperate species found in Europe (including Denmark, Finland, France, Germany, Hungary, Italy, Romania, Sweden, Switzerland, UK, USSR, Yugoslavia) and North America (Canada, USA) and extending to central and South America (Argentina, Peru, Uruguay), N. Africa (Libya, Morocco, Tunisia), Japan, Australia and New Zealand. TRANSMISSION: Not fully understood, though inoculation experiments have demonstrated that infection occurs in mature vegetative plants (possibly through meristematic tissue), not seeds or flowers (22, 240; 24, 511). Once established, infection is systemic, probably overwintering in the root system and spreading by vegetative multiplication of host plants as well as from plant to plant (24, 511; 19, 720).

Abstract A description is provided for Gibberella fujikuroi var. subglutinans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On several hosts of economic importance in the Gramineae; also on a wide range of hosts represented by the following families: Amaryllidaceae, Anacardiaceae, Bromeliaceae, Chenopodiaceae, Convolvulaceae, Cruciferae, Iridaceae, Leguminosae, Liliaceae, Malvaceae, Marantaceae, Musaceae, Palmae, Rosaceae, Rutaceae, Sterculiaceae (14: 708; 31: 515; 36: 501; 40: 89 and Herb. IMI). DISEASES: Causes a seedling blight, and root, stalk and kernel rot of maize; also on heads and stalks of sorghum associated with a foot and stem rot, and causing a stem rot and top rot of sugar-cane ('pokkah boeng'). Other records include a wilt of Crotalaria, a heart rot of leaves of banana and Manila hemp, and fruit rot of banana, cacao and pineapple. There appear to be no references to pathogenicity to rice. Also entomogenous on cereal stem borer larvae and other insects (27: 71; 33: 382; 38: 141, 740). GEOGRAPHICAL DISTRIBUTION: Africa (Central African Republic, Congo, Ghana, Ivory Coast, Kenya, Mauritius, Morocco, Reunion, Sierra Leone, South Africa, Southern Rhodesia, Tanganyika, Uganda); Asia (Formosa (Taiwan), Hong Kong, India, Java, Indo-China, Philippines, Syria); Australasia (Hawaii, New South Wales, New Zealand, Victoria); Europe (Czechoslovakia, Germany,? Italy, Poland, Romania); Central America & West Indies (French Antilles, Honduras, Trinidad); North America (Canada, United States); South America (Argentina, Peru). (CMI Map 191). TRANSMISSION: Both seed and soil-borne. Air-borne ascospores produced from perithecia on over-wintered plant debris or on dead stalks of sugar-cane at the beginning of the rainy season are also important sources of infection (30: 344). The pathogen may also be disseminated on pupae and adults of cereal stem borers and their parasites in sugar-cane (33: 382).

Over the past 1000 years, rats ( Rattus spp.) have become one of the most successful and prolific pests in human society. Despite their cosmopolitan distribution across six continents and ubiquity throughout the world's cities, rat urban ecology remains poorly understood. We investigate the role of human foods in brown rat ( Rattus norvegicus ) diets in urban and rural areas over a 100 year period ( ca AD 1790–1890) in Toronto, Canada using stable carbon ( δ 13 C) and nitrogen ( δ 15 N) isotope analyses of archaeological remains. We found that rat diets from urban sites were of higher quality and were more homogeneous and stable over time. By contrast, in rural areas, they show a wide range of dietary niche specializations that directly overlap, and probably competed, with native omnivorous and herbivorous species. These results demonstrate a link between rodent diets and human population density, providing, to our knowledge, the first long-term dietary perspective on the relative value of different types of human settlements as rodent habitat. This study highlights the potential of using the historical and archaeological record to provide a retrospective on the urban ecology of commensal and synanthropic animals that could be useful for improving animal management and conservation strategies in urban areas.
