Change Management in the Public Sector: A Preliminary Analysis
No full textThis paper presents a literature review of 64 studies published in the Journal of Organizational Change Management, aiming at examining the current state of research on organizational change and public sector management, with a focus on the use of change management and process optimization in public administrations. The discussion focuses primarily on a keyword analysis, based on the results obtained with bibliographic and bibliometric tools. The keywords were divided into four categories based on their frequency and persistence: intermittent, trendy, core, and emerging topics. The VOSviewer software package was used to identify the relationships between the keywords. The review highlights the importance of organizational change and change management in the public sector, emphasizing the need for careful planning, effective communication, employee involvement, and a supportive organizational culture. The results of the review provide valuable insights into the current state of research in these areas and can inform future research on change management in the public sector. This literature review focuses on change management practices with a specific focus on the public sector, which is rarely investigated in the literature. Also, it provides a detailed analysis of the existing knowledge about this topic. In addition, the use of multivariate statistical techniques provides an in-depth understanding of the relationships among keywords, thus providing an original contribution to the literature on the theme
Random vs Class-based allocation policies: impact of the warehouse parameters on the distance traveled by pickers
No full textWithin most distribution centers, activities are managed with low levels of automation, often becoming cost and labor-expensive due to the occurrence of inefficiencies. Picking and product allocation are the activities most likely to be subjected to these risks and, in literature, numerous contributions aim to optimize them. The present study aimed to evaluate the impact that different strategic variables, such as the routing policy (RP), the warehouse shape factor, the numerosity of the picking list, or the location of the Input/Output (I/O) points, have on the variability of the average distances traveled by pickers to fulfill a picking mission (d). This evaluation was done by comparing, through a simulation approach, different levels of class-based allocation policies versus a random allocation policy under different operating scenarios. An ANOVA was then performed to rank the variables and their interactions according to their impact on d in each scenario. The RP turned out to be the parameter with the strongest impact, covering between 23% and 36% of the variance; at the same time, moving from mild to strong class-based scenarios, the impact of the interaction of I/O and RP increased more than that of I/O alone. Possible future research activities were finally outlined
Radio Frequency Identification in the Food Industry: Preliminary results from a bibliometric analysis on case studies
No full textRadio Frequency Identification (RFID) technology allows for automatic and real-time identification of items, by simply attaching a tag to them. In the last years, it was implemented in several contexts mainly for tracking purposes, including the food supply chain and the related logistics activities. In this field, in fact, traceability is essential and above all mandatory, for guaranteeing food quality, customer safety and waste reduction. The aim of this paper is to present the preliminary results from a bibliometric analysis on case studies and applications, in order to derive the last trends. In more detail, bibliographic research was carried out through the Scopus database, and a total of 52 documents resulted from a query having “RFID”, “food industry” and “case study” as keywords. Typical bibliographic features were investigated (i.e., temporal evolution, type of study, most common journal and conference, most prolific authors, geography, citations, keywords), but also interesting contents-related issues were derived, namely the type of food in question, the main aim of the RFID implementation and the level of tagging (i.e., item-, secondary or pallet- level). Research turned out to be quite steady over time among the sample, with most of the published documents produced in the United States and Italy; moreover, an interest towards the item-level tagging was also deduced

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
