Quality Analysis of Mobile Applications
Get PDFMobile applications are defined and different types of mobile applications are identified. Characteristics of quality are defined and their indicators are constructed to measure levels. Take into account 11 parameters analysis for mobile applications, which are arranged using weights and do a detailed analysis of the system of weights. For SMSEncrypt application performance measurement is done using an aggregate indicator based on the obtained weights system.Mobile, Application, Quality, Analysis, Indicator
A Decade of Trials of Interferon-Alpha for Chronic Hepatitis C. A Meta-Regression Analysis
No full textThe most relevant randomized controlled trials of interferon-alpha (IFN) for naive patients with chronic hepatitis C (CHC) published in a decade, just before appearance of pegylated IFN trials in 2000, were included in this paper. Its purpose is to review the relationship between sustained biochemical response in active versus control group versus usual clinical variables as IFN regimens, cirrhosis, genotype and versus less frequently addressed variables as funding, methodological quality or location of principal author. Meta-analysis estimates of global treatment effect varied according to trial design: group 1=IFN versus placebo/no treatment, 32 RCTs, 2499 pts, OR 9.5 (6.3-14.2); group 2a=comparison of IFN schedules, 43 RCTs, 7454 pts, OR 1.6 (1.4-1.9); group 2b=IFN+other drugs versus standard IFN, 30 RCTs, 4737 pts, OR 2.0 (1.6-2.6). Fixed effects (arm-level) meta-regression on the complete data set (171 arms, 10,580 pts) revealed that sustained response was most likely in experimental arms of IFN+ribavirin or other drugs (OR 2.4), arms using yearly schedule (OR 2.0), trial principal author from Asia (OR 1.7), trial sample size >200 (OR 1.4) and arms enrolling less than 50% of cirrhotics (OR 1.3). Moreover, focus was on some significant interactions too, as the effect of trial''s quality interacting to the recorded funding (more benefit if no-profit, less if for-profit) and the effect of trial funding interacting to the location of first author (more benefit if from Asia). Three main effects (experimental arm, cirrhosis, funding) and one interaction (funding*location of principal author) explained 31% of between study variability in a random-effect meta-regression. In a subgroup analysis on a data set including available information on HCV genotype (93 arms, around 7000 pts), meta-regression revealed that genotype 1 or 4 less than 50% per arm and specialistic journal were significant predictors of either biochemical (transaminases) or virological (HCV-RNA) sustained response, in a model including the same main effects identified in the complete data set analysis. Finally, although mostly captured by different IFN regimens along time, heterogeneity of effect in a large set of (not-pegylated) IFN trials was also explained by HCV genotype and variables of quality and reporting, such as trial''s principal author from Asia
Pisma Louisa Adamiča nečaku Tinetu
Get PDFThe article is based upon the publication of a number of letters and short notices (in anauthentic transcript) that Louis Adamic sent to the author, his nephew Tine Kurent, between 1946-50. The contents of these letters as well as some of the author’s spelling errors reveal, besides his current activities and future plans, the writer’s emotional stateat the time when he was writing them.Prispevek se opira na objavo nekaterih pisem (v avtentičnemu prepisu), ki jih je Louis Adamič poslal svojemu nečaku Tinetu Kurentu v letih 1946 - 50. Tako vsebina kot tudi nekatere pravopisne napake v pismih odkrivajo - poleg podatkov o Adamičevih tedanjih dejavnosti in načrtih - tudi njegova čustvena stanja v trenutkih, ki jih je pisal
Painting the Self in a Study of Modernity : Using Art in Anthropological Research
Get PDFThis essay proposes the application of the concepts of ‘small’ and ‘big’ stories theorised by Lyotard (1984) to the discipline of visual anthropology, by focusing on the issues of ‘generalisation’ and ‘individuality’. The primary question on which this work is focused is: ‘how do we integrate individual case-studies with generalisations in anthropological research in a way that provides a balanced account of small and big stories?’. To answer this question, the author shares the theoretical and methodological challenges of using art within her current research on Nepal.
The use of art in anthropology has been proposed as a method of enquiry in recent years (Sweetman, 2009; Sullivan, 2012; Tine, 2017) for its ability to convey a deeper understanding of non-verbal contents than can be achieved through text alone (Cox & Wright, 2012; Prosser & Loxley, 2008). Consequently, a revision in the aims, methods and expressive tools of the discipline (Clifford & Marcus, 1986; Marcus & Fisher, 1999; El Guindi, 2011; Foster, 1995) and a discussion on the topics of ‘subjectivity’, ‘generalisation’ and ‘individuality’ in ethnography and ethnology is now urgent. Furthermore, the issue of how to incorporate and represent all of the individual stories taken from field research, which has been central in modern anthropological debate (Geertz, 1988), must now be dealt with in the new context of anthropological/artistic production.
This article suggests that the artist-anthropologist will have to give an account of all the relations occurring within the research project, including the subjectivity of the author and the mediation between generalisation and individual narratives. To achieve this, the use of a personal style and of a clear semiotic codification system will be necessary
Summary of Comments on Analysis of Hungarian red deer trophies by means of Principal component analysis in two different counties
No full textAuthors analyzed data of 9 trophy parameters (weight of the antler, length of main beam, length of brow tine, length of bay tine, length of tray tine, circumference of coronet, lower circumference of main beam, upper circumference of main beam, number of total tines) of 6868 red deer stags shot between 1997 and 2007 and estimated ages were between 4-16 years, from two counties of Hungary (5946 from Somogy and 921 Bcs-Kiskun). General linear model was used to evaluate age and county effects on the trophy parameters. Age was a significant source of variation for all studied traits while county affected most of the studied parameters. Consequently the dataset was analyzed separately for each county. Low to high correlations (adjusted for age effect) were found both in Somogy (r=-0.04 - 0.80) and for Bcs-Kiskun (r=-0.06 - 0.70). Using principal component analysis (with orthogonal rotation) 4 factors were extracted which accounted for 73 % and 75 % of total variance in Bcs-Kiskun and Somogy county respectively. The first factor represents the circumferences of the trophy, the second factor the main tines (brow, bay, tray) of the antler. The third and fourth factors represented the number of total tines of the trophies and the length of main beam respectively. These identified factors could be considered in selection/evaluation of the trophies in Hungarian red deer instead of the traditionally used measurements in order to maintain type and quality of the red deer trophy in Hungary
The Post-Research Ethics Analysis (PREA) Project
Get PDFAUTHOR AFFILIATION: Dónal O'Mathúna, The Ohio State University, United States, and Dublin City University, Ireland, [email protected] media can be accessed here: http://streaming.osu.edu/knowledgebank/PREA/PREA_Session4_OMathuna_20190325.mp4A series of presentations provide an overview of the PREA project and preliminary findings. An initial scoping review led to the Research Ethics Tool commissioned by the project funders, R2HC. Then a more thorough PREA Systematic Review was conducted, led by Mr Steven Martin of Anglia Ruskin University, UK. The methods and search results are presented, followed by an overview of the 13 Themes identified in the analysis. Then Prof Tine Van Bortel introduced the qualitative research component, beginning with the training for the in-country interviewers. Mr Nawaraj Upadhaya of HealthNet TPO discusses the coordination of the interviews in Nepal, Afghanistan and South Sudan. Dr Yimtu Mulate, Addis Ababa University conducted the interviews in Ethiopia. The qualitative analysis was discussed by Prof Van Bortel and Dr Ainul Hanafiah of the University of East London, UK. The methods of the analysis and the 10 Themes identified were presented, as well as overall conclusions from the findings
