The R0 package: a toolbox to estimate reproduction numbers for epidemic outbreaks
Obadia Thomas,Haneef Romana,Bo?lle Pierre-Yves
BMC Medical Informatics and Decision Making , 2012, DOI: 10.1186/1472-6947-12-147
Abstract: Background Several generic methods have been proposed to estimate transmission parameters during an outbreak, especially the reproduction number. However, as of today, no dedicated software exists that implements these methods and allow comparisons. Results A review of generic methods used to estimate transmissibility parameters during outbreaks was carried out. Most methods used the epidemic curve and the generation time distribution. Two categories of methods were available: those estimating the initial reproduction number, and those estimating a time dependent reproduction number. We implemented five methods as an R library, developed sensitivity analysis tools for each method and provided numerical illustrations of their use. A comparison of the performance of the different methods on simulated datasets is reported. Conclusions This software package allows a standardized and extensible approach to the estimation of the reproduction number and generation interval distribution from epidemic curves.

Abstract: Background The US Food and Drug Administration Amendments Act requires results from clinical trials of Food and Drug Administration–approved drugs to be posted at ClinicalTrials.gov within 1 y after trial completion. We compared the timing and completeness of results of drug trials posted at ClinicalTrials.gov and published in journals. Methods and Findings We searched ClinicalTrials.gov on March 27, 2012, for randomized controlled trials of drugs with posted results. For a random sample of these trials, we searched PubMed for corresponding publications. Data were extracted independently from ClinicalTrials.gov and from the published articles for trials with results both posted and published. We assessed the time to first public posting or publishing of results and compared the completeness of results posted at ClinicalTrials.gov versus published in journal articles. Completeness was defined as the reporting of all key elements, according to three experts, for the flow of participants, efficacy results, adverse events, and serious adverse events (e.g., for adverse events, reporting of the number of adverse events per arm, without restriction to statistically significant differences between arms for all randomized patients or for those who received at least one treatment dose). From the 600 trials with results posted at ClinicalTrials.gov, we randomly sampled 50% (n = 297) had no corresponding published article. For trials with both posted and published results (n = 202), the median time between primary completion date and first results publicly posted was 19 mo (first quartile = 14, third quartile = 30 mo), and the median time between primary completion date and journal publication was 21 mo (first quartile = 14, third quartile = 28 mo). Reporting was significantly more complete at ClinicalTrials.gov than in the published article for the flow of participants (64% versus 48% of trials, p<0.001), efficacy results (79% versus 69%, p = 0.02), adverse events (73% versus 45%, p<0.001), and serious adverse events (99% versus 63%, p<0.001). The main study limitation was that we considered only the publication describing the results for the primary outcomes. Conclusions Our results highlight the need to search ClinicalTrials.gov for both unpublished and published trials. Trial results, especially serious adverse events, are more completely reported at ClinicalTrials.gov than in the published article. Please see later in the article for the Editors' Summary
How Do the Evolution and Innovation of Social Network Analysis Matter to Computer Science and Communications?  [PDF]
Romana Xerez
Social Networking (SN) , 2013, DOI: 10.4236/sn.2013.23013

This paper provides a comprehensive overview of evolution and innovation in social network analysis to the paradigm of social networking. It explains how the development of sociological theory and the structural properties of social groups matter to computer science and communications. Authors such as Moreno, John Barnes and Harrison C. White provide evidence of a growing body of literature addressing the networking of people, organizations and communities to explain the structure of society. This perspective has passed from sociology to other fields, changing understandings of social phenomena. Social networks remain a potent concept for analyzing computer science and communications. This paper shows how and why this has occurred and examines substantive areas in which social network analysis has been applied—mainly how the advantages of graphic visualization and computer software packages have influenced SNA in different audiences and publics leading to the unfolding of social networking to different audiences and publics.

Katrin Schütz: Geschlechterentwürfe im literarischen Werk von Lou Andreas-Salomé unter Berücksichtigung ihrer Geschlechtertheorie. Würzburg: Verlag K nigshausen & Neumann 2008
Romana Weiershausen
querelles-net , 2009,
Abstract: Katrin Schütz hat eine Studie zu Geschlechterkonzeptionen in Lou Andreas-Salomés Frühwerk vorgelegt, in der auch die bislang wenig berücksichtigten literarischen Texte der Autorin ausgewertet werden. Die Anlage zielt auf eine überblicksdarstellung, hinter der die differenzierende Reflexion der einzelnen Thesen zurück steht: Schütz geht es um die Konturierung einer Typologie. Durch die erweiterte Textgrundlage wird dabei Neues erschlossen, woraus sich anregende Impulse für die Jahrhundertwende-Forschung ergeben. Katrin Schütz’s study of gender conceptions in Lou Andreas-Salomé’s early work considers those literary texts often ignored by scholarship. The study is constructed as an overview, in light of which a differentiated reflection on the individual theses falls short: Schütz intends to formulate a typology. The expanded textual basis allows for the creation of something new, which will in turn provide inspirational impulses for turn-of-the-century research.

Abstract: A high-quality manufacturing system should be capable to meet the company goals. Moreover, it is essential for any organization that its manufacturing system should be aligned with company’s strategy. There is always a potential for improvement in components of manufacturing systems but it is also essential to identify theparticular areas of the components that need improvement. In this paper, we have discussed the most appropriate criterion for good manufacturing systems with the help of a survey that indentified the importance of seven different criteria according to the experts experience and we ranked them accordingly.
Tolerance to Allelopathy by Effective Microorganisms (EM) in Chickpea (Cicer arietinum L.)
Rukhsana Bajwa,Bushra Haneef,Arshad Javaid
Pakistan Journal of Biological Sciences , 1999,
Abstract: Aqueous leaf extract of Syzygium cumini (L.) Skeels significantly reduced the root and shoot growth, pod yield and uptake of nitrogen and phosphorus in chickpea (Cicer arietinum L.). Effective Micro-organisms (EM) application provided sufficient relief to chickpea against allelopathic stress due to aqueous leaf extract. Consequently the root and shoot growth, pod yield and shoot nitrogen content of EM inoculated plants were significantly enhanced as compared to non-inoculated plants. However, adverse impact of extract on shoot phosphorus content remained unchanged by EM application.
Nail changes and disorders among the elderly
Singh Gurcharan,Haneef Nayeem,A Uday
Indian Journal of Dermatology, Venereology and Leprology , 2005,
Abstract: Nail disorders are frequent among the geriatric population. This is due in part to the impaired circulation and in particular, susceptibility of the senile nail to fungal infections, faulty biomechanics, neoplasms, concurrent dermatological or systemic diseases, and related treatments. With aging, the rate of growth, color, contour, surface, thickness, chemical composition and histology of the nail unit change. Age associated disorders include brittle nails, trachyonychia, onychauxis, pachyonychia, onychogryphosis, onychophosis, onychoclavus, onychocryptosis, onycholysis, infections, infestations, splinter hemorrhages, subungual hematoma, subungual exostosis and malignancies. Awareness of the symptoms, signs and treatment options for these changes and disorders will enable us to assess and manage the conditions involving the nails of this large and growing segment of the population in a better way.
