Anchoring Effects in Inventory Control Decisions
No full textWhen supply chain managers are responsible for making forecasting decisions, those decisions may be influenced by a number of decision-making biases, one of which is anchoring. Anchoring is defined as "the disproportionate influence on decision makers to make judgments biased toward an initially present value." The impact of anchoring has been tested in a number of different fields, ranging from valuation of products to legal judgments. However, it has not been researched extensively in the area of supply chain management. This research aims to fill this gap by presenting an anchor to subjects who are making decisions in the field of inventory management to see what, if any, impact anchoring has in this context. The results from this research will inform managers whether they need to be careful about the presence of anchors in the information they provide to decision makers. Limiting the potential impact of the anchoring bias will lead to better inventory management. Effective inventory management has the power to greatly reduce costs by eliminating the risk of stockouts and holding excess inventory, both of which create additional expenses for companies
Capacity Crisis In The United States Trucking Industry, A Conceptual Model From A Theory Of Constraints Perspective
No full textAlthough we do not operate in a static world, the Theory of Constraints can help us reach our goals by focusing our attention to the important constraints or drivers that are limiting the performance of the U.S. trucking industry. In order to explain the capacity crisis affecting the United States trucking industry, this paper develops a theoretical framework based on the Theory of Constraints to suggest that there are three drivers of significance: the national truck driver shortage, the infrastructure, and sustainability initiatives. Not only do these three drivers of significance interact, they have the combined ability to produce multiplicative effects on individuals, companies, industries, and the economy alike. By focusing on these particular constraints or drivers, we can better manage them and gradually devise strategies to alleviate them using the constraint-based approach
Supply Chain Implications In Regards To Consumer Behavior In Online Retail: Site-To-Store Versus Direct Shipping
No full textThe purpose of this research is to explore consumer behaviors in online retail. As traditional brick-and-mortar firms adopt online shopping as a sales channel, it is of the utmost importance that they understand how consumers in this space behave. With the advent of site-to-store shipping from large retail firms like Walmart and Target, it is important to know how customers perceive the shipping option when compared to the direct shipping option that is standard among online retail. Specifically, this research aims to find a convenience value for direct shipping over site-to-store (also known as Order Online, Pick-Up at Store or simply "in-store pick-up"). Additionally, the paper aims to provide some insight into how this convenience value might change based on item price. The research also addresses several demographics to determine if these have any impact on consumer preferences. Finally, the paper identifies the satisfaction levels of those customers for both the direct and in-store pick-up shipping options
Toward A Better Understanding Of Political Risk In The International Supply Chain
No full textThis study aims to investigate how firms of various sizes in various industries perceive, detect, and mitigate political and legal risk in their international supply chains. Due to the ambiguity of political risk in today's interconnected business environment, companies struggle to find effective ways to handle political disruptions as they inevitably arise. Firms' perceptions of risk and those firms' risk mitigation strategies were determined through a series of structured interviews with supply chain executives with international supply chain experience. The candidates were chosen based on experience, industry, and company size. It was determined that although political risk affects virtually every company with international operations (and even those without), there is still no strategy to detect and mitigate political risk that can be applied to any company's business model, regardless of industry, size, or region in which they operate. This lends itself to the idea that political risk is still a relatively unclear area of research. Future areas of research include a more in-depth investigation into regional discrepancies and the impact that capital structure has on the risk mitigation strategies of firms
Humanitarian Logistics of Pharmaceutical Donations
No full textThe study focuses on the humanitarian logistics of pharmaceutical donations. The research focuses primarily on the upper-section of the supply chain, meaning pharmaceutical companies (suppliers) and various nonprofits. The goal of this paper was to obtain a more detailed understanding of humanitarian logistics and the hurdles that pharmaceutical donations must overcome. Three interviews were conducted with three different companies each representing best practices in different humanitarian scenarios. Interviews were conducted with Defyrus Inc., the International Trachoma Initiative, and Novartis. The interviews provided valuable insight into humanitarian logistics and will provide useful information to other companies in the industry
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
