The paper responds to research problems related to the implementation of large-scale investment projects in waterways in Europe. As part of design and construction works, it is necessary to indicate river ports that play a major role within the European transport network as intermodal nodes. This entails a number of challenges, the cardinal one being the optimal selection of port locations, taking into account the new transport, economic, and geopolitical situation that will be brought about by modernized waterways. The aim of the paper was to present an original methodology for determining port locations for modernized waterways based on non-cost criteria, as an extended multicriteria decision-making method (MCDM) and employing GIS (Geographic Information System)-based tools for spatial analysis. The methodology was designed to be applicable to the varying conditions of a river’s hydroengineering structures (free-flowing river, canalized river, and canals) and adjustable to the requirements posed by intermodal supply chains. The method was applied to study the Odra River Waterway, which allowed the formulation of recommendations regarding the application of the method in the case of different river sections at every stage of the research process.

Suitable land is an important prerequisite for crop cultivation and, given the prospect of climate change, it is essential to assess such suitability to minimize crop production risks and to ensure food security. Although a variety of methods to assess the suitability are available, a comprehensive, objective, and large-scale screening of environmental variables that influence the results—and therefore their accuracy—of these methods has rarely been explored. An approach to the selection of such variables is proposed and the criteria established for large-scale assessment of land, based on big data, for its suitability to maize (Zea mays L.) cultivation as a case study. The predicted suitability matched the past distribution of maize with an overall accuracy of 79% and a Kappa coefficient of 0.72. The land suitability for maize is likely to decrease markedly at low latitudes and even at mid latitudes. The total area suitable for maize globally and in most major maize-producing countries will decrease, the decrease being particularly steep in those regions optimally suited for maize at present. Compared with earlier research, the method proposed in the present paper is simple yet objective, comprehensive, and reliable for large-scale assessment. The findings of the study highlight the necessity of adopting relevant strategies to cope with the adverse impacts of climate change.

This paper describes a systematic methodology for selecting independent variables to be considered in large-scale research problems. Five specific procedures including brainstorming, prototype interface representation, feasibility/relevance analyses, structured literature reviews, and user subjective ratings are evaluated and incorporated into an integrated strategy. This methodology is demonstrated in the context of designing the user interface for a telephone-based information inquiry system. The procedure was successful in reducing an initial set of 95 independent variables to a subset of 19 factors that warrant subsequent detailed analysis. These results are discussed in terms of a comprehensive sequential research methodology useful for investigating human factors problems.

In 2015, the predominantly visible minority immigrant community of Herongate, in Ottawa, Ontario, was slated for redevelopment by its landlord, Timbercreek Asset Management. This redevelopment involved mass eviction of the incumbent tenants, demolition of the existing affordable housing and its replacement with luxury rentals, which, by all indications, are beyond the financial reach of the former Herongage tenants. This paper seeks to problematize large-scale residential real estate redevelopment in Canada and examine its impact, using the Herongate situation as a case study. Among other things, it profiles the Herongate community, its history and present redevelopment, and explores the legal framework, and the limits thereof, constraining mass evictions of this type in Ontario. The findings indicate that the selection of Herongate for redevelopment was not fortuitous; generally, racialized and immigrant communities like Herongate are disproportionately likely to be selected for large-scale redevelopment projects, and thus subjected to mass-evictions. Further results suggest that the dissolution of the Herongate community – and the attendant dislocation of its members – has exacted a pronounced social and economic toll and compounded the racial discrimination already experienced by the former Herongate residents, most of whom are visible minorities. The paper concludes with an appeal to imbue the redevelopment process with a greater regard for social justice, and a right to housing as a policy solution to address the injustice caused by real estate redevelopment.

Many municipalities, park districts, and nonprofit organizations have begun monitoring nonmotorized traffic on multiuse trails as the need for information about the use of facilities has grown and relatively low-cost sensors for automated monitoring have become available. As they have gained experience, they have begun to move from site-specific monitoring on individual trails to a more comprehensive monitoring of trail networks. This case study review compares strategies developed by 10 organizations for monitoring traffic on multiuse trails, including local, multicounty, statewide, and multistate trail networks. The focus is on approaches to the design of monitoring networks, particularly the rationales or objectives for monitoring and the selection of monitoring sites. It is shown that jurisdictions are following principles of monitoring established by FHWA and that the design of monitoring networks is evolving to meet new challenges, including monitoring large-scale networks. Relevant outcomes and implications for practice are summarized. The researchers concluded that FHWA guidelines can be adapted to many circumstances and can increase information for decision making. Trail monitoring is informing decisions related to facility planning, investment, and safety.

AbstractIn this chapter, after summarising the key conceptual challenges related to the measurement of asylum migration, we briefly outline the history of recent migration flows from Syria to Europe. This case study is intended to guide the development of a model of migration route formation, used throughout this book as an illustration of the proposed model-based research process. Subsequently, for the case study, we offer an overview of the available data types, making a distinction between the sources related to the migration processes, as well as to the context within which migration occurs. We then propose a framework for assessing different aspects of data, based on a review of similar approaches suggested in the literature, and this framework is subsequently applied to a selection of available data sources. The chapter concludes with specific recommendations for using the different forms of data in formal modelling, including in the uncertainty assessment.

The article proposes a multi-attribute decision making (MADM) approach, which is applied to the problem of optimal selection of the investment projects. This novel methodology comprises two stages. First, it makes ranking of projects based on TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method presented in hesitant fuzzy environment. We consider the case when the information on the weights of the attributes is completely unknown. The identification of the weights of the attributes is made in the context of hesitant fuzzy sets and is based on the De Luca-Termini information entropy. The ranking of alternatives is made in accordance with the proximity of their distance to the positive and negative ideal solutions. Second stage of the methodology allows making the most profitable investment in several projects simultaneously. The decision on an optimal distribution of allocated investments among the selected projects is provided using the method developed by the authors for a possibilistic bicriteria optimization problem. An investment example is given to illustrate the application of the proposed approach.

Purpose This study aims to extend the literature on marketing communications by exploring the effect of placing products in humorous scenes. It aims to ascertain the prevalence of placement scenes associated with humor in television programs and the effect of humor on brand persuasiveness. Design/methodology/approach The study used a two-phase research process. A content analysis of prime-time television programing was conducted to map the relative prevalence of brands placed in humorous contexts and for the selection of research stimuli. This was followed by a large-scale experimental study of 1,100 television viewers in Hong Kong with real stimuli that had been digitally manipulated. Findings The study found that a humorous context did enhance recall of placed brands but its effect on brand attitudes was mediated by audience involvement in the viewing and moderated by psychological trait reactance. Interestingly, and in contrast to conventional advertising, placing brands in a humorous context led to lower involvement in the viewing, which, in turn, resulted in lower brand attitudes. Individuals with low trait reactance were more positive toward brands placed in a non-humorous context than individuals with high trait reactance while individuals with high trait reactance were more positive toward brands placed in a humorous context, though the difference was less prominent. Research limitations/implications The findings help to illustrate when and how a humorous context contributes to the recall of and attitudes toward placed brands. Practical implications The results also facilitate marketers and program producers to choose the best placement context and design more effective placement strategies. Originality/value This research is the first to empirically examine the effect of a humorous context on the unaided recall of and attitudes toward brands placed in television programs.
