Implemented sustainable public transport solutions and social expectations for the city transport system of Szczecin
No full textThe issues discussed in this article concern the basic assumptions for the sustainable development of public transport in cities. We discussed the need and direction of changes that occur in public transport that were referred to both users and transport organizers in cities. To this end, we characterized the activities which encourage urban residents to use forms of urban transport and the limitations of commuting via individual transport. The purpose of this article was to determine the main directions and areas of development of public transport in Szczecin. In addition, we also presented the solutions applied in the city transport system aimed at making it sustainable. In addition, an attempt was made to determine the impact of selected solutions on residents’ transport behaviors. The survey research method was used to examine societal opinions and expectations regarding public transport. We also approximated the basic investments that have been implemented to make transport more sustainable and the activities for the development of electromobility. Future research directions on the sustainability of transport in the city, and especially on limiting vehicular traffic, were also discussed
Carsharing as an example of smart mobility – comparative study Poland–Germany
No full textModern cities are focused on the implementation of the assumptions of sustainable transport development. They invest in modern solutions and intelligent technologies that improve the mobility of residents and reduce energy consumption and pollution emitted by means of transport. This article deals with issues of smart urban mobility and carsharing, in particular, as one of the examples of the implementation of sustainable transport policy. The objective of this article is a comparative analysis of the pace of development of the carsharing markets in Poland and Germany. The analysis is carried out using statistical and comparative analysis methods. In addition, for a complete presentation of the problem raised, a literature analysis is performed. The research area covers two countries, Poland and Germany, from which ten cities for each are selected for analysis. In addition, to achieve the assumed objective, we also present the basic assumptions of smart mobility and solutions used in cities, and then determine the increase in the number of cars driving in the carsharing system. In addition, the factors influencing the change in transport patterns of urban residents are analyzed, and the importance of modern communication technologies in the development of carsharing systems is emphasized. The results of the analysis can be used as a tool to support the decisions of city authorities in the field of transportation management and, in particular, the implementation of carsharing systems. They also present the dependencies of the spread of this solution in a given urban space. They indicate the largest problems that may affect the introduction of this solution as an element of the city’s transportation system
Factors Determining the Selection of a Logistic Operator
No full textThe aim of the article is to present and analyze major groups of factors that are considered by companies when selecting a logistic operator, and to demonstrate how a given factor influences the quality of performed tasks. It systemises factors and analyses more closely those which are currently of biggest importance in the process of time and costs optimization in logistic processes from the point of view of both a logistic operator and a customer. It shows also some solutions which may be helpful when selecting external Contractor for services
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
