Additive Manufacturing And Mass Customization: some key examples to reflect on
No full textAdditive manufacturing (AM) has been evolving rapidly in the last decade and captivated the imagination of the industry and academia. Currently AM is widely seen in scientific literature as enabler for mass customized manufacturing. However, the research on why this is the case is still lacking. This research explores this “why” by analyzing exemplary cases. Results show that there are MC applications in which AM competes with conventional manufacturing and presents some explanatory mechanisms. The research provides a fine-grained understanding on the impact of AM on MC capability that can be used by researchers and practitioners
Product Configurators for Additively Manufactured Products: Exploring their peculiar characteristics
No full textThe capability of realizing individually customized products with complex geometries makes additive manufacturing (AM) ever more considered by companies engaged in mass customized manufacturing. In order to be exploited in the market, the AM allowed geometry freedom has to be transferred to the customers for the customer-specific customization. Notably, this is a new request posed to product configurators (PC). So, in this research we ask: How is this request being answered by pioneers who engage in this challenge? Are there other new requests that AM poses to configurators? The present paper aims at answering these exploratory questions by looking at how these issues have been considered in existing literature and by providing some examples. We hope that considerations derived from this investigation will open a discussion on this topic in the product configuration research community with the goal to identify peculiar PC capabilities needed to customize additively manufactured products using PCs
Performance Measurement and Improvement Method for Leather Footwear Industries
Full text linkNowadays, there is strong desire for business enterprises to measure, analyze, evaluate and improve their performance due to an increasing competition from current dynamic business environment. Even though, the Ethiopian Leather Footwear Industry (LFI) has huge potential for boosting the country economy, the overall performance of the sector is unsatisfactory due to factors like poor performance measurement and improvement practices, poor planning and control practices and high manufacturing cost. Most performance measurement and improvement methods used so far are not well designed to learning and rarely consider the personal ambition of employees, which results in insufficient improvement in the organizations’ performance. Thus, the aim of this study is to assess and evaluate the current performance management practice of Ethiopian LFIs and eventually forward a better firm level total performance improvement technique. A survey questionnaire is used to collect relevant data from fourteen LFIs. Furthermore, benchmarking to identify performance gaps and objective oriented cause and effect analysis to investigate the root causes of low performing industries have been used. The analyzed data confirmed low performance of the industries is due to poor performance measurement and improvement technique. In addition, most methods adopted by the industries doesn’t bring expected change yet due to the limitations with the tools and implementation strategies. As a result, a new method for performance measurement and improvement called “total performance scorecard” along with compatible performance measurement framework and implementation guideline which leads to better performance of the Ethiopian footwear industry has been introduced
Framing startups survival research at the crossroad of entrepreneurship, strategy and business model: a literature review and a research agenda
Full text linkStartup survival depends on entrepreneurs’ ability to create value by identifying and exploiting
new opportunities while developing a viable business model. This article contributes to a body of
fragmented research spanning three key domains—entrepreneurship, strategy, and business
models—focusing on how startups leverage strategy and business models to be competitive. To
this end, we conduct a systematic literature review on the identification and exploitation of
opportunities by startups, as well as on the definition of their strategy and business model to
survive in competitive markets. Our study provides an overview of the literature on the subject,
identifying the main strands and their main findings, and promising avenues for future research to
enhance both academic understanding and entrepreneurial practic
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
