Abstract

In this paper, we analyze the extent to which low-income countries integrate into the global knowledge production network. We develop an (undirected) research collaboration model based on which we identify the drivers of global research collaboration using publication data of the field Business and Economics from the Web of Science and macroeconomic data from the United Nations Educational, Scientific and Cultural Organization Institute for Statistics. Network and dynamic panel regression techniques are employed. Our results show that (i) reciprocal preferential attachment and the homophily between countries reinforce scientific collaboration, (ii) there is no evidence that low-income countries are becoming better integrated into the global knowledge production over the years, despite their active participation in international reserach collaboration, while (iii) high-income countries show a basic willingness to cooperate with them, which, in turn, promotes the integration of low-income countries, although this willingness seems to decline; and (iv) as to low-income countries, they have little choice but to invest more in education and R&D in order to advance in the global knowledge production network.

Abstract

I Dear Editor, i Total mesorectal excision (TME) is a standard procedure for rectal cancer surgery [[1]]. The dissection process for the upper slice and the display of the final effect. gl Middle layer (lateral border of the rectum): after the gap between the posterior and anterior rectum is opened sufficiently, a clear connective tissue distribution and course are noted along the lateral border as the middle layer. Treatment of the lateral ligament, avoiding damage to the pelvic nerve plexus and protecting the bladder and sexual function of patients, are the hallmarks of TME surgery.

42. The prices of open access publishing: The composition of APC across different fields of sciences

Abstract

Modern media technologies paved the way to the open access movement. Instead of the traditional academic subscription and publishing model, which allowed few big publishers to charge excessive publishing fees, the open access model raises the hope for a fair system, where scientific content is freely accessible and thus the dissemination of research work becomes possible at little cost. However, previous literature pointed out that big publishers seem to be able to preserve their market power when going from the subscription-based model to the open access model. In this paper, we take a closer look at the differences across disciplines. The publication routines in Social Sciences, Physical Sciences, Life Sciences and Health Sciences differ to a substantial extent. On these grounds, we test whether there are also differences in the explanations for the article processing charges (APC) across these disciplines. For doing so, we combined various data sources such as the dataset of the "Directory of Open Access", the "OpenAPC Initiative" and the "CiteScore Metrics". Our regression results show that the differences across the four fields in terms of publication habits and endowment levels allow publishers to exploit their market power to different extents.

49. Drivers of article processing charges in open access

Abstract

Large publishing companies have been dominating scientific publishing for long, which leads to high subscription fees and inhibited access to scientific knowledge. At digital era, the opportunity of an unrestricted access appears feasible, because the cost of publishing should be low. It is no longer the readers and libraries to pay subscription fees, but scientific organizations and authors themselves who pay for the cost of having their article published. As the data shows, there is a tremendous variance of article processing charges (APC) across journals, which obviously cannot be explained by the costs. One of the explanatory variables could be reputation, but it only contributes less than 5% to the variance in APC. This study is meant to shed light on the various determinants of APC. Based on data from the OpenAPC Initiative, the Directory of Open Access Journals, the Journal Impact Factor and the Essential Science Indicators of Web of Science, we employ ANOVA and multivariate regressions. The results show that market power plays an important role to explain APCs, inter alia, through market concentration, market position of individual publishers (publisher size), and the choice of hybrid publishing model.

Abstract

The paper applies economic theories to give an overview of the emerging phenomenon of digital personal assistants (DPAs). A DPA is an intelligent automated system that interacts with the user through a dialogue in natural language, and meanwhile applying third-party services to obtain information and perform various actions. We analyze the benefits of increasing usage of DPAs, such as reduction of transaction costs, enhanced organization efficiency, procompetitive effects, and boosting the e-commerce economy. Besides benefits, however, adopting DPA in life may also contain some risks and downsides, which may reduce the positive welfare effects or even lead to decreasing welfare: biased services, market power on the DPA market and economic dependence on a dominant DPA, potential leveraging of DPA suppliers' market power into neighboring markets, personalized data (ab)use and privacy, media bias and manipulation of public opinion.
