    Zadeh's (min-max, standard) fuzzy logic and various other logics are commutative, but natural language has nuances suggesting the premises are not equal, with premises contributing to the conclusion according to their prominency. Therefore, we suggest variants of salience-based, noncommutative and non-associative fuzzy logic (prominence logic) that may better model natural language and reasoning when using linguistic variables. Noncommutative fuzzy logics have several theoretical and applicative motivations to be used as models for human inference and decision making processes. Among others, asymmetric relations in economy and management, such as buyer-seller, provider-user, and employer-employee are noncommutative relations and induce noncommutative logic operations between premises or conclusions. A class of noncommutative fuzzy logic operators is introduced and fuzzy logic systems based on the corresponding noncommutative logics are described and analyzed. The prominence of the operators in the noncommutative operations is conventionally assumed to be determined by their precedence. Specific versions of noncommutative logics in the class of the salience-based, noncommutative logics are discussed. We show how fuzzy logic systems may be built based on these types of logics. Compared with classic fuzzy systems, the noncommutative fuzzy logic systems have improved performances in modeling problems, including the modeling of economic and social processes, and offer more flexibility in approximation and control. Applications discussed include management and engineering problems and issues in the field of firms’ ethics or ethics of AI algorithms

    City marketing and convention bureaus value propositions in the post-covid timeThe role of convention bureaus across the world is to market destinations and cities.This paper explores destination marketing in the post pandemic time. It focusses on thevalues that convention bureaus, a key actor in the meetings industry, propose topotential visitors. The concept of value propositions (VPs) is commonly regarded as astrategic tool for organizations to communicate what and how they will provide benefitsto clients in their offerings of products or services (Payne, Frow and Eggert 2017, Payneet al. 2020). A value proposition is a central part of the business model. VPs can bethought of in terms of promises made to clients or to market segments in externalcommunication (Grönroos and Voima 2013). This calls for an appropriate packaging andpresentation of the values in the communication of organisations (Payne, et al. 2017).From a strategic perspective, VPs affects the process communicating and deliveringvalues (Lanning 2020). Previous research of VPs within in tourism studies include valueco-creation and co-destruction in tourism services (Assiouras et al. 2022), value andtourist brand loyalty (Bose et al. 2022), tourism stakeholder value-co creation (Carrasco-Farré et al. 2022), value propositions in digitalisation processes (Endres et al. 2020) valuepropositions for community building (Butler and Szromek 2019), power in tourismmarketing (Kannisto 2016) and values in experience design (Tussyadiah 2014). The topicappears however to be understudied from a communication perspective and also withrespect to how unexpected events, such as the pandemic, frame the processes ofcommunicating values. The aim of this paper is to advance the knowledge about valuepropositions socio-cultural dimensions by exploring how benefits for meetings bookersand visitors are discursively constructed. The study will answer three questions: how isvalue proposed in the marketing communication of convention bureaus, and whatprofessional meetings discourses are formed in the post covid time?Case, method and theoryTexts and images in the online marketing of 20 convention bureaus (CBs) was collectedbetween May 2022 and March 2023. Dispersed across five world continents, most CBsare located in large cities. A CBs main purpose is to increase the number of meetings ina destination. CBs collaborate with companies in its area to market their offerings, andthey are often a unit of a DMO of a city or a municipality's business department. Themeetings industry increased its activity in the beginning of 2022, when all restrictionswere gradually lifted, and therefore the data constitute an example of marketing thatwas planned and executed during a crisis. The material was imported and text-scannedin NVivo software. Codes were created inductively, by identifying presentations ofbenefits in chunks of texts and images that were manually coded as value propositions,screenshot by screenshot. Inspired by discourse theory (Wetherell et al. 2001), thesecond step of the analysis aimed for a more abstract level. The theory wasoperationalized by looking for reoccurring expressions used to propose value, terms,narratives, symbols, metaphors, and images, and by identifying things that are excluded,and ambiguities in the communication. A set of identified values emerged, as a map ofhow convention bureaus on a global level imagine the meetings demand. The analysis2discusses some vantage points that the CBs depart from. The analytical perspective thusprovides a broad societal interpretation of the themes.FindingsTwo main VP discourses emerged. First, the offering of “The meeting in a destination” isconstructed as place-bound meetings. Place is represented in images of historicalbuildings, spectacular nature, or references to place specific professional networks. Thecommunicated benefits emphasise physical interactions and location in relation to otherplaces. The place bound discourse constructs an essential need of being and engaging ininteractions and experience place, for successful meetings. The CBs engage in aplaceification of professional meetings.Second, the “Sustainable meetings” is a morally packaged offering, that is often basedon presenting benefits of ethical concern such as expressions of care for theenvironment or displays of certifications and expert lists of wise consumption choices.This offering thus constructs morally conscious and responsible choices at the center ofa good meeting. Sustainable consumption is constructed as a norm, in this ethicificationof the professional meetings offering. In sum, the representations relate to differentnorms like mobility and the ethical. The first emphasises experiences of place, whichpartly contradicts the offering of sustainability, The placeification contradicts theethicification of meetings, in so far that places require physical infrastructures andtravelling. The ethicification of meetings stress on the other hand travelling aspotentially harmful for the environment. The sustainability theme does not stress lesstravelling, it rather suggests alternative forms.Discussion and conclusionsThe communication can be interpreted as formations of new norms emerging in relationto change in society. The meeting industry has always emphasised the value of a specificlocation for meetings, an essential part of the tourism industry business models.Revenues depend on sold rooms, dinners, and personal service in that place.Experiences of place requires people to be there. This communication may thereforeseem like a given vantage point. However, digitalisation of society has acceleratedduring Covid-19 pandemic and it seems to have paved a way for customer segments thatdo not want to, or cannot not travel to a remote destination, for different reasons.Especially urgent during the pandemic and to some extent still valid, digital meetingformats are still used. The meeting industry have had to address the question ofmobility, where digital meetings formats could be part of a possible venue in asustainable direction. Carbon emissions from aviation is a significant contributor toclimate change while a lot of people around the world go to meetings by plane, on aregular basis. It may be that the industry addresses these challenges by promotingsustainable meetings. Hence the communication discursively establishes the meetingsindustry as a player within sustainable development. Communication can trivializeconceptions of sustainable challenges and this study suggests that value propositionsare powerful communicative tools and that value propositions emerge in relation tochange in society.References3Assiouras, Ioannis, et al.

    An Everyday Approach to Agritourism Production in Southern Ontario

    Get PDF
    This dissertation is a nuanced interpretation of the production of space in the context of agritourism in Southern Ontario. It uses everyday life as a theoretical framework to expand conceptualizations of tourism production by enabling a discussion of how cultural practice is central to economic activity. I use agritourism to show how, in addition to being an important economic activity, tourism production is a culturally informed process with intrinsic value concerned with home and family, and contributes to individual utility, self-worth, identity and well-being for the tourism producer. In Southern Ontario, Agritourism has grown in popularity in the past thirty years. It is well-known as an economic diversification strategy but needs to be better understood as a cultural practice involving the social relations and everyday interactions of individual life contexts. I argue that the everyday reveals the production logic of well-being that is not necessarily based on an economic mentality but on the day-to-day negotiation of the home as a private place of residence, a place of work, and a tourism attraction open to the public. The question driving this dissertation is: to what extent does the everyday reveal alternative forms of production related to agritourism that are not necessarily driven by profit but by achieving a greater sense of well-being? At the heart of the research is an intimate knowledge of the farmers experience. I investigated these experiences by way of participant observation and semi-structured conversational style interviews. In addition to completing 27 interviews with a total of 32 self-employed people involved in operating/managing/running small to medium-large, and relatively large sized agritourism operations/businesses, I visited 16 agritourism attractions as an agritourist. An everyday approach shows that emotional well-being is a success factor in the production process, which points to agritourism as more than an economic activity. Adaptation, personal growth, family bonds and legacy, emotional connections, value systems, and protecting the privacy of the home are non-economic characteristics of tourism production that are about the embodied doings of day-to-day tasks that keep the destination running in the long term by preserving the well-being of the farmer and his/her family

    Unmet goals of tracking: within-track heterogeneity of students' expectations for

    Get PDF
    Educational systems are often characterized by some form(s) of ability grouping, like tracking. Although substantial variation in the implementation of these practices exists, it is always the aim to improve teaching efficiency by creating homogeneous groups of students in terms of capabilities and performances as well as expected pathways. If students’ expected pathways (university, graduate school, or working) are in line with the goals of tracking, one might presume that these expectations are rather homogeneous within tracks and heterogeneous between tracks. In Flanders (the northern region of Belgium), the educational system consists of four tracks. Many students start out in the most prestigious, academic track. If they fail to gain the necessary credentials, they move to the less esteemed technical and vocational tracks. Therefore, the educational system has been called a 'cascade system'. We presume that this cascade system creates homogeneous expectations in the academic track, though heterogeneous expectations in the technical and vocational tracks. We use data from the International Study of City Youth (ISCY), gathered during the 2013-2014 school year from 2354 pupils of the tenth grade across 30 secondary schools in the city of Ghent, Flanders. Preliminary results suggest that the technical and vocational tracks show more heterogeneity in student’s expectations than the academic track. If tracking does not fulfill the desired goals in some tracks, tracking practices should be questioned as tracking occurs along social and ethnic lines, causing social inequality
