Applying Grey System Theory to predict default probability in construction industry
No full textThe prediction of business failure is an important and challenging issue that has served as the impulsion for many academic studies over the past decades. The widely applied methods to predict the risk of business failure were based on financial ratio analysis; therefore, the purpose of this thesis is to explore the possibility of applying Grey System Theory for predicting default probability of construction firms by analyzing financial history data. In the present research, the author introduces a framework of the bankruptcy probability valuation relying on the 19 initial financial ratios. First, Synthetic Degree Incidences ρ of considered firms are calculated and combine these ρ values, the default probability of firms as well as the importance of financial ratios as predictors will be identified. In this research scope, the author proposes 3 models correspond with difference history consequence data (3 years, 4 years and 5 years). Then, using ROC curves to point out which one is the most favorable consequence data for model (correspond to the highest AUC value). After the suitable consequence data (4 years) was chosen, the other effected factors like as X0, θ and the combo of key variables were considered. Some warnings as well as recommendations are highlighted for those who concern of applying grey analysis model to forecast default probability of construction firms
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
The Impact of COVID-19 on Packaging Design and Production: A Case Study
Full text linkThe COVID-19 pandemic was one of the biggest challenges in recent history that affected all aspects of socio-economic life, as well as the ecological environment of our planet. Before the pandemic, the packaging industry captured the interest of governments because of their commitments regarding designs for sustainability. These commitments intended to reduce single-use plastic packaging, increase the use of recyclable materials, and use eco-friendly materials. The crisis, however, has negatively impacted, and changed these priorities. The aim of this study is to provide an overview of the changes in packaging design and production during the COVID-19 pandemic, focusing on a case study in the food packaging industry. A secondary data analysis method was conducted to collect information for the process of comparing and evaluating the factors affecting the change of this industry, and a case study was conducted for the food packaging sector. The obtained research results showed that these companies had the ability to improvise in the context of the COVID-19 pandemic, and suggesst a potential model in order to solve urgent problems in the new context.

The effect of enforcement actions on lead Arranger’s Reputation: Evidence from syndicated loans.
Full text linkA formal enforcement action on banks for non-compliance with laws and regulations
has an adverse effect on bank’s reputation. This thesis examines such case,
enforcement action appears as a reputational burden to banks that cause the decrease
in bank market’s share and the need to attract more potential participants. Moreover,
the impacts of enforcement actions are different to bank’s size and vary by their
types. A larger size bank experiences a larger effect from enforcement actions. The
more severe enforcement actions are enacted, the more intensive impacts bank
receive. The results are proved through an empirical research using syndicated banklevel
data and sample of enforcement actions from 1982 – 20
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
