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

Let

be a prime of

such that
G

of

-invariants for the representation

is totally real, we show that these automorphic
-invariants agree with the Fontaine–Mazur
-invariant of the associated

Queueing systems constitute a central tool in modelling and performance analysis of e.g. telecommunication systems and computer systems. Often the systems are complex (for instance, communication network, operating system) and contains many queues, which form a network of queues, i.e. a queueing network. The author considers a multichannel retrial queuing system GI / G/ С/ 0 / L / /G (with С channels, generilised input flow, general service times, general orbit's sojourn times, and orbit of capacity of L) in the article. Distribution functions of intervals between moments of calls' arrival, service and sojourn times of retrials are of general form. Such systems as GI / G/ С/0 / L/ /G can be represented as a set of Kolmogorov equations (an analytical model). It is very hard and sometimes impossible to obtain explicit formulas when trying to solve such set of equations, especially when it comes to generil distribution times. That is why an gorithm of statistical modeling of GI / G / С/ 0 / L //G system is introduced in order to estimate stationary average number of demands in the system. Graphical results are given
Investigating Reddit to detect subreddit and author stereotypes and to evaluate author assortativity
Get PDFIn recent years, Reddit has attracted the interest of many researchers due to its popularity all over the world. In this article, we aim at providing a contribution to the knowledge of this social network by investigating three of its aspects, interesting from the scientific viewpoint, and, at the same time, by analysing a large number of applications. In particular, we first propose a definition and an analysis of several stereotypes of both subreddits and authors. This analysis is coupled with the definition of three possible orthogonal taxonomies that help us to classify stereotypes in an appropriate way. Then, we investigate the possible existence of author assortativity in this social medium; specifically, we focus on co-posters, that is, authors who submitted posts on the same subreddit
Elaboration on Kwapien's theorem: Representing bounded mean zero functions f as coboundary f = g ◦ T − g
No full textIn [8] Kwapien proved that every mean zero function f ∈ L∞[0, 1] we can write as f = g ◦ T − g for some g ∈ L∞[0, 1] and some measure preserving transformation T of [0, 1]. However, as was discovered in [4] there is a gap in the proof for the case that f is not continuous. The aim of this bachelor thesis is filling in that gap in the proof. We first extend Kwapien’s proof for continuous functions to certain other measure spaces. Thereafter, we use the method of proof suggested by Kwapien, to proof the theorem for mean zero function f ∈ L∞[0, 1] for which λ(f−1({x})) = 0 for all x ∈ R. Using this result we then proof that every mean zero function f ∈ L∞[0, 1] can be written as a sum f =(g1 ◦ T1 − g1) + (g2 ◦ T2 − g2) where g1, g2 ∈ L∞[0, 1] and where T1, T2 are measure preserving transformations of [0, 1]. We finish this thesis with an application of Kwapien’s theorem in the study to singular traces Applied Mathematic
ASO Author Reflections: Conization Before Radical Hysterectomy Improves Disease-Free Survival in Early Stage Cervical Cancer
No full textPast
A well-known randomized study demonstrated that minimally invasive radical hysterectomy was associated with poorer disease-free and overall survival in patients with early stage cervical cancer, when compared with an open approach.1 Despite not yet understanding the technical reasons for this result, different options have been proposed to explain the difference in oncological outcomes. One of these is potential peritoneal ‘contamination’ at time of colpotomy: this possibility is intuitively more likely in cases of bulky tumors.2,3 In this context, conization before radical hysterectomy may reduce the risk of peritoneal exposure to cancer tissue, maintaining the oncological safety of the surgical procedure.
Very few studies have investigated the impact of conization in cervical cancer survival, demonstrating an association between conization and reduced risk of recurrence.3
Present
In this multicenter, retrospective, observational cohort study, we analyzed the survival outcomes of a population of FIGO 2009 stage IB1 cervical cancer, by comparing the group that underwent conization with the group that did not undergo conization before radical hysterectomy. Three hundred and thirty-two patients (166, 50% in each group) were included after balance with a propensity match analysis. On the conization specimens, 14.4% and 85.6% of patients had negative and positive surgical margins, respectively. However, 41.6% of conization patients did not have residual tumor on the hysterectomy specimen, therefore significantly reducing the risk of peritoneal tumor ‘contamination’.
Patients undergoing conization before radical hysterectomy were less likely to receive adjuvant treatment (p < 0.001) and had a better 5-year disease-free survival than patients who did not receive conization (89.8% vs. 80.0%, respectively; p = 0.010). No difference in 5-year overall survival (97.1% vs. 91.4%, respectively; p = 0.114) and in recurrence pattern (p = 0.115) was reported between the two groups. Conization before radical hysterectomy and tumor diameter ≤ 20 mm were independently associated with reduced risk of recurrence.
Future
More and more evidence supports the role of protecting maneuvers performed at the time of radical hysterectomy to avoid peritoneal exposure to tumor cells. Amongst these, the avoidance of using a uterine manipulator, the closure of the vaginal cuff and, now, pre-operative conization, can be listed as actions aimed at reducing or eliminating the risk of peritoneal tumor contamination during minimally invasive surgery.4 Nevertheless, at the moment, most international guidelines and societies’ statements are cautious regarding the use of minimally invasive radical hysterectomy, particularly for tumors > 20 mm, unless within the setting of clinical trials. Prospective randomized trials are ongoing to further confirm or deny the detrimental effect of a minimally invasive approach to radical hysterectomy.5 Importantly, these trials promote or aim to assess the use of protective maneuvers to avoid peritoneal tumor exposure at the time of colpotomy, and conization could be proposed as one of these. Nevertheless, a randomized trial to specifically compare the survival of patients undergoing or not undergoing pre-operative conization, may be necessary in the future to better define and personalize the correct management of early stage cervical cancer.
