Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Institutional changes and dynamics in the European Aviation Sector:Implications for Tourism
This chapter covers three areas of institutional changes in the European aviation sector that may significantly affect the dynamics of the tourism industry. Further to the introduction, airlines are discussed in section two; airports are analysed in section three; and air navigation service provision are presented in section four. The dynamics of these three pillars and the interrelationship with the tourism industry is explored in section five. Among others, the chapter argues that when a proper systemic approach is followed any smart relaxation of regulatory and infrastructural constraints will have positive repercussions on tourism growth and development not only of central places but also of more peripheral regions. Finally, section six concludes and discusses the way forward
Making Domestic Destinations Attractive:An Empirical Study from Mountainous Greece
Domestic Tourism has not been researched as much as international tourism has. In addition, mountain tourism tends to be associated with skiing and other snow or winter related activities mostly. This field of tourism becomes even less researched when the country is considered a popular sea and sun summer destination where international and domestic tourist arrivals peak during the summer months. The purpose of this paper is to highlight the value of domestic mountain tourism at a popular domestic destination which is primarily accessible by surface means of transport, therefore international tourists find it harder to reach. From a regional perspective, the paper addresses the impact the financial crisis had on domestic tourism length of stay and discusses how these destinations can adapt their tourism offering to become more attractive and competitive.The empirical part of the paper consists of primary data randomly selected by questionnaire during the holiday period between Christmas and New Year, a period where the destination is experiencing high occupancy rates and visitor numbers. The analysis of the data indicates that there are some dominant source markets followed by a high proportion of day visitors who could potentially convert to tourists. The findings of this paper contribute to the literature regarding domestic and mountain destinations, not necessarily linked to snow activities. Conclusions can be applied to other popular domestic destinations not only in Greece but other countries too and applied accordingly for their benefit
Carry-on baggage on low-cost carriers. A no-frills journey?
Airlines around the world carry on top of passengers, their baggage. Carried baggage adds to the total weight of the aircraft resulting in increased fuel consumption. Increased fuel prices led airlines around the world to introduce baggage fees to improve their revenues against their increased operating costs. This option was initially introduced in hold luggage, baggage that is not taken in to the cabin by the passenger. Over time though, several airlines, primarily low cost carriers, introduced fees for carry on baggage too. In 2019, 4.397 billion people flew according to the World Bank (2020) when ICAO reported 4.5 billion passengers for the same period (ICAO, 2019). According to the same report, ICAO estimates that 1.4 billion passengers in 2019 were carried by low-cost carriers, approximately 31 per cent of the world total scheduled passengers. The annual growth in passenger numbers in 2019 compared to the previous year was 5.3 per cent for low-cost carriers, almost 1.5 times the rate of the world total average passenger growth which was 3.6 per cent (ICAO, 2019). Despite their massive growth and their increasing market share which accounted for 31 percent in 2019, low-cost carriers do not have a common approach on the size of cabin baggage or the pricing policy. There are airlines who charge, airlines that do not charge at all, and other that charge or not, depending on the type of fare of ancillary services (add on) the passenger purchased. These differences are addressed in this paper in order to create groups of carriers that have very similar policies on pricing and accepting carry on baggage. There is limited literature related to baggage and pricing policies around them, let alone policies related to carry on baggage. One of the first scholars referring to passenger accompanied luggage is Williams (1977) who referred to rail passengers and their luggage. This study examines the baggage policies of the best low cost carriers in the world according to the 2019 Skytrax World Airline Awards. These are fifty low cost carriers that carried over 1 billion passengers in 2019, just under 25% of the world’s airline passengers. The data were collected by accessing each airline’s internet page and the information was collated in order to examine, baggage dimensions, weight and pricing policies. It is evident that there is no common approach leading to misinterpretations, confusion and inconsistency when it comes to carry on baggage policies. The main findings of this study highlight those differences and conclude with suggestions for the airlines or policy makers in order to streamline the policies covering carry on baggage. In addition, 2019 has been a very successful year for the low cost sector and the international tourism market where operations were not affected by external factors like in the following years. The study focuses on low cost carriers due to the popularity of these carriers, their increased market share and the concept that flying on a low cost carrier is cost effective and straight forward. The lack of literature in the above subject might open a new area for research and discussion in order to provide solutions to the issue that is being addressed
