Sourcing models under credit guarantee mechanism with information asymmetry
No full text本研究主要探討配銷商對於其上游中小企業供應商之資金缺乏與供應風險之議題。擁有充沛資金與信用的配銷商，將建構一信用擔保機制，以解決上游中小企業供應商資金取得困難問題。除此之外，供應鏈風險還包含配銷商對於供應商之成本不確定以及其交貨給配銷商之供貨不確定。因此為了降低這些不確定性的傷害，誘因合約於單供應商採購模型及雙供應商採購模型將試圖降低不確定造成的傷害。本研究以配銷商(買方)立場，透過信用擔保機制的建立，採用誘因合約於單供應商採購模型及雙供應商採購模型進行決策。 面臨資金缺乏供應商在供貨不穩定下，配銷商考慮其利潤時，使用雙供應商採購策略會比單供應商採購策略好。無論哪種模式， 銀行的借貸成數、無效率供應商的交貨滿足率的增加或降低配銷商遇到斷鏈機率時，配銷商的利潤增加。配銷商遇到斷鏈機率的降低會比供應商提升交貨滿足率重要，因此身為供應鏈一整合者，配銷商應該擬一策略是能改善銀行的借貸成數、無效率供應商的交貨滿足率與配銷商遇到斷鏈機率，以便整合供應鏈。對於供應商而言，配銷商能利用本身為資金擔保者立場下，要求供應商應該將交貨滿足率改善為條件，並且對於銀行而言，信保機制能讓銀行多一業務，配銷商應該在容許獲利之下，盡可能的保證銀行獲利，並讓銀行提供更高的貸款成數。In buyer-supplier relationships, financial shortcoming and supply risks are important concerns. To solve a small and median enterprise supplier’s financial difficulty, distributors can offer credit guarantees. To manage supply disruption and cost uncertainties in the supply chain, distributor can adopt incentive contracts. This is a legal strategy in sole sourcing and dual sourcing situations. This study attempts to examine the issue of a credit guarantee mechanism from the buyer’s perspective, with incentive theory under a sole sourcing or dual sourcing strategy. Under cash constraint of the unreliable supplier A, dual sourcing strategy is better than sole sourcing strategy. As loan-to-value increases, fill rate increases or disruption rate decreases, the expected profit of the distributor increases. A decrease of disruption rate is prior to an enhancement of fill rate. As a coordinator, the distributor is expected to take loan-to-value, fill rate and disruption rate into account to integrate supply chain. The distributor may take the enhancement fill rate as a condition to be guarantor and promising the profit for the financial institution. Consequently, the distributor is able to mitigate supply risk by sourcing strategy under the mechanism in which the financial difficulty for the supplier is solved
Patient safety in work environments: Perceptions of pediatric healthcare providers in Taiwan
No full textBackground: Extensive research on the link between the organizational characteristics of the work environment and patient safety in a healthcare organization has been conducted; yet, only a few studies have concentrated on care providers in a pediatric unit. Objectives: To determine the correlation between different work environment factors impacting patient safety in a pediatric care unit from the perspective of registered nurses working in these units. Design: Cross-sectional design. Data sources and methods: The study was conducted with 155 registered nurses from a pediatric unit in a medical center in Taiwan with the Chinese version of the Safety Attitudes Questionnaire (SAQ) 2014-2017. Results: Teamwork climate, higher job satisfaction, and better working conditions are linked to positive perceptions of patient safety culture. Emotional exhaustion is negatively related to most dimensions of patient safety. Conclusion: Teamwork climate, job satisfaction, working conditions, and emotional exhaustion were identified as critical factors impacting the patient safety climate. Implications for nursing or health policy: Investments to improve teamwork climate, job satisfaction, and working conditions and reduce emotional exhaustion may have a positive effect on patient safety in pediatric care units.This study was funded by Institute of Wuhan Studies of Jianghan University with the grant number of IWHS20192027, and Hubei University of Economics with the grant number of XJ17BS41; XJ201901; XJ201902
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
