Purpose: This study aims to present the key systemic changes in the Polish book evaluation model to focus on the publisher list, as inspired by the Norwegian Model. Design/methodology/approach: In this study we reconstruct the framework of the 2010 and 2018 models of book evaluation in Poland within the performance-based research funding system. Findings: For almost 20 years the book evaluation system in Poland has been based on the verification of various technical criteria(e.g. length of the book). The new 2018 model is based on the principle of prestige inheritance(a book is worth as much as its publisher is) and is inspired by the publisher list used in the Norwegian Model. In this paper, we argue that this solution may be a more balanced policy instrument than the previous 2010 model in which neither the quality of the publisher nor the quality of the book played any role in the evaluation.Research limitations: We work from the framework of the 2018 model of book evaluation specified in the law on higher education and science from 20 July 2018, as implementation acts are not available yet. Practical implications: This study may provide a valuable point of reference on how structural reforms in the research evaluation model were implemented on a country level. The results of this study may be interesting to policy makers, stakeholders and researchers focused on science policy. Originality/value: This is the very first study that presents the new framework of the Polish research evaluation model and policy instruments for scholarly book evaluation. We describe what motivated policy makers to change the book evaluation model, and what arguments were explicitly raised to argue for the new solution. 展开更多

The Book of Songs is a book of propriety passing on rites and teaching people by the form of poetry with unique logic and rhetoric.“Guan Ju”is the most typical poem deducing the propriety of humans from the laws of nature,which is acceptable,convinced and obeyed by the people naturally,friendly and eloquently.Therefore,the logic and rhetoric in The Book of Songs can be reconciled and self-consistent in the poetic thinking of the unity of heaven and humans. 展开更多

The Book of Songs is the first collection of Poems in China,which is a very important milestone in the history of Chinese literature.There are abundant metaphorical expressions in The Book of Songs,providing valuable resources for linguistics,rhetoric and literature research.This study selects the most representative metaphors of women and marriage in The Book of Songs as the research object.Guided by Lakoff and Johnson’s conceptual metaphor theory,this study explores the metaphorical translation in Pound’s Book of Songs from the perspective of cognitive effect.It is found that Pound mainly adopts the translation strategies of vehicle equivalence,vehicle conversion and metaphor to simile in the process of translating female metaphors and marriage metaphors in The Book of Songs. 展开更多

In this study, we use Chinese A-share stock market data from 1995 to 2005 to test the persistence of the size and valueeffect and the robustness of the Fama-French three-factor model in explaining the variation in stock returns.Wefind that the three-factor model can explain the common variation in stock returns well.However, it is mis-specifiedfor the Chinese stock market.We demonstrate that the size effect and the book-to-market effect are significant andpersistent over our sample period.Interestingly, the book-to-market effect for China is much stronger than the averageones in mature markets and other emerging markets documented by Fama and French (1998).Moreover, we find noevidence to support the argument that seasonal effects can explain the results of the multifactor model.Last, our mixedobservations on firm-specific fundamentals suggest that the risk-based explanation proposed by Fama and French(1995) cannot shed light on the size and BM effect for China.In view of the features of the Chinese stock market, weinstead argue that China’s size and book-to-market effect may be attributed to syndicate speculators’ manipulation andmispricing caused by irrational investor behavior. 展开更多

Korean academic libraries are facing a serious space shortage problem due to the inability to uphold the rapidly increasing amount of printed materials despite having expanded the number of physical facilities. Data computerization has been considered as a solution to the issue, but deliberation for the High Density Book Storage System has been on the rise because of its impressive method of preserving printed materials in a realistic facility. Despite the different methods of print material storage, Korean academic libraries have largely focused on investing in the least efficient method of compact shelving to solve this issue. It is hypothesized that the misuse of funds on inefficient systems is occurring due to the lack of knowledge about the high-density book storage systems like the Harvard model. In order to propose a realistic solution to the academic library space shortage crisis on a logical basis, it is imperative that a study of academic librarians is conducted to investigate their knowledge on such efficient storage systems. 展开更多

Binomial N-mixture models are commonly applied to estimate abundance unaffected by imperfect detection,but are known to be sensitive to violations of assumptions.One of the model’s assumptions,the independence of detections has rarely been tested.It requires that during a survey,detection of one individual does not affect detection of another individual.This assumption can be frequently violated in passerine birds,which exhibit territorial behaviour by singing,since neighbouring individuals are likely to motivate each other to vocalize,leading to non-independence in singing activity and in the following detection rate.Here,we explored this phenomenon with the generalized,binomial version of the N-mixture model,where detection probability is decomposed into availability probability φ-which can be interpreted as per capita song rate or the probability of vocalising-and actual detection probability p,given vocalisations take place.Using repeated counts of the Collared Flycatcher(Ficedula albicollis)as a case study,and treating the maximum observed counts C_(maxi) at a site i as an explanatory covariate for φ,we showed that per capita song rates increased with observed counts at a site.Hence,if song rates vary due to local abundance,including C_(maxi)as an explanatory variable for song rate addressed with φ,helps to explain this variation(which otherwise goes undetected)and improves inferences under the model.This had strong effects on the resulting abundance estimates:if this relationship was ignored in the models,total estimated population sizes were consequently lower by as much as 22-27%,compared to when this effect was included.Since it is likely that song rates may commonly be density-dependent in birds manifesting territorial behaviours by singing,further tests addressing violations of independence assumptions in these models are needed.As suggested by Kery and Royle(2016),despite some form of circularity likely being involved,modelling heterogeneity in the detection process with the help of C_(maxi)in standard N-mixture models(which,given availability,conflate availability with detection in a single parameter)should be applicable as well. 展开更多

Color language has important meaning for children’s picture books.Understanding children’s preferences in terms of color language will be helpful when designers model computerized picture books in order to adapt to children’s visual senses and effectively stimulate children’s interest in reading.In this study,we aimed to further explore the general characteristics of children’s preference for colors,color depth and color matching forms in picture books.For the study,256 children between the ages of three and six were selected and divided into four groups.According to the implementation needs of the children’s color preference test,these childrenwere asked to complete a series of tasks so that their choices in the tasks could subsequently be analyzed.The tasks included making the following choices:selecting their preferred colors from nine options(red,orange,yellow,green,cyan,blue,purple,black and white);selecting their preferred color brightness fromthree different color shades;and indicating their preferences in relation to complementary colors,matching colors and pure colors.The experimental results showed that children aged between three and six mainly favor red,blue and yellow,and colors with a high degree of brightness.As children grow older,boys tend to prefer blue,and girls tend to prefer pink,with red remaining the favorite color of both genders.As for complementary colors,matching colors and solid colors,three-to six-year-old children prefer solid colors.In conclusion,it seems that color language preferences in children between the ages of three and six are very similar,which could be of use when designing children’s picture books to match their visual vocabulary and psychological cognition. 展开更多

It is important to evaluate course books. The author analyzes "Reading and Writing Book" of "21st Century College English" based on the Nuttal’s reading model. Firstly, this model is presented in the open- ing part. Secondly, then the author discusses suitability of the course book from its content variety, authenticity and the training of language skills. Thirdly, how Nuttal’s reading prin- ciples and reading skills are reflected in such book is analyzed. Based on the discussion and analysis, conclusions are drawn that it is suitable for reading instruction; many of the reading principles and reading skills are well embodied and trained in this book. Finally suggestions are presented in the conclusion part. These suggestions include: 1) this book should be adopted more authentic materials such as poems, advertisements, recipes, travel guidebooks and so on; 2) teachers may present and train students’ reading skills systematically; 3) teachers should provide more and better non-linear text, such as col- ored pictures, reference book list, etc. 展开更多

COVID-19 comes from a large family of viruses identied in 1965;to date,seven groups have been recorded which have been found to affect humans.In the healthcare industry,there is much evidence that Al or machine learning algorithms can provide effective models that solve problems in order to predict conrmed cases,recovered cases,and deaths.Many researchers and scientists in the eld of machine learning are also involved in solving this dilemma,seeking to understand the patterns and characteristics of virus attacks,so scientists may make the right decisions and take specic actions.Furthermore,many models have been considered to predict the Coronavirus outbreak,such as the retro prediction model,pandemic Kaplan’s model,and the neural forecasting model.Other research has used the time series-dependent face book prophet model for COVID-19 prediction in India’s various countries.Thus,we proposed a prediction and analysis model to predict COVID-19 in Saudi Arabia.The time series dependent face book prophet model is used to t the data and provide future predictions.This study aimed to determine the pandemic prediction of COVID-19 in Saudi Arabia,using the Time Series Analysis to observe and predict the coronavirus pandemic’s spread daily or weekly.We found that the proposed model has a low ability to forecast the recovered cases of the COVID-19 dataset.In contrast,the proposed model of death cases has a high ability to forecast the COVID-19 dataset.Finally,obtaining more data could empower the model for further validation. 展开更多
