Determining the In-Vitro Transcriptional Regulon of SigG in Nostoc punctiforme
No full textNostoc punctiforme is a cyanobacterial species that is capable of adapting its morphology into several different states of which the spore-like akinetes are the least understood. A time-course array previously revealed that Npun_F4153, a putative ECF sigma-encoding gene, was significantly upregulated upon akinete induction along with Npun_F4154, the cognate anti-sigma factor to Npun_F4153. Based on sequence alignments, Npun_F4153 was initially designated as putative RpoE-like protein, SigG, with subsequent experiments having since supported this identification. In this thesis, bioinformatics analysis suggests that Npun_F4154, designated SapG, shares homology with RseA-like sequences in organisms both from its own phylum and others. A knockout mutant strain of sigG, previously thought to not show any difference in phenotype from a WT strain, was discovered to exhibit a more buoyant cell pellet compared to WT N. punctiforme in log-phase vegetative cells. Furthermore, nitrogen deprivation in an attempt to induce heterocysts resulted in a massive rate of hormogonia formation in sigG mutant relative to WT. Attempts to complement the mutant were unsuccessful. Notably, sigG mutant showed increased susceptibility to lysozyme stress in both vegetative and akinete-induced strains, while akinete-induced mutant showed increased susceptibility to cold stress relative to akinete-induced WT cells. Once these phenotypic findings were established, N. punctiforme RNA polymerase core enzyme, as well as hexahistidine-tagged SigG protein were expressed and purified. Selected promoter templates based on previous in-vivo regulon results were also amplified, of which one was shown to be a direct target of SigG under heterocyst-inducing conditions. Encouraging preliminary results using these purified products with selected promoter templates and optimized in-vitro reaction conditions culminated in a runoff-transcription microarray-analysis (ROMA) using sheared, N. punctiforme genomic DNA templates. The in-vitro regulon generated from this experiment was in turn analyzed to develop a consensus sequence logo and for in-silico SigG regulon determination. Finally, regulons from all three approaches were compared to determine the most likely gene promoter targets of N. punctiforme SigG.California State University, Northridge.

No full textEvaluation of the mountain sites on the basis of soil trophic index (SIGg)
No full textThe correct assessment of the site conditions is the basis of the good management of forest areas. The aim of this study was to find a set of soil properties, which allow separating the diverse sites in terms of the soil productivity. We used 180 locations in the Carpathians and the Sudety Mountains for testing. The study plots were located in transects from the foothills to the top along the slopes, taking into account the variability of site conditions, geological substrate and exposition. The index was calculated on the basis of the content of <0.02 mm particles, the sum of exchangeable base cations, soil acidity and the ratio between total N content and organic C in the humus−mineral horizon. The soil trophic index for mountain areas (SIGg) that include the climatic factor was introduced. The factor is defined as the 650/altitude ratio for a given point above sea level. In the mountains, the content of <0.02 mm fraction, the sum of exchangeable base cations and soil acidity were determined in the column of 1 m² of the soil cross section and depth of 1 m (1 m³ of volume) due to the lower depth of the soil profile. The SIGg correctly separates soil of different productivity as the properties closely associated with the stable elements of the soil, expressing its production and properties, which reflect the current state of the soil environment, were used in the construction SIGg
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
ITACARE-P/SIGG/SIGOT/SICGE position paper on elderly cardiac patient referral to cardiac rehabilitation
No full textThe Italian Association for Cardiovascular Rehabilitation and Prevention (ITACARE-P) together with the Società Italiana di Gerontologia e Geriatria (SIGG); Società Italiana di Geriatria Ospedale e Territorio (SIGOT); SICGE, Società Italiana di Cardiologia Geriatrica (SICGE) released a joint position paper to guide referrals of elderly cardiovascular patients discharged from Geriatric wards to Cardiac Rehabilitation (CR) facilities. The document provides rationale and operative recommendations for appropriateness (i.e. qualifying diagnosis) and priority criteria to overcome mismatch between potential demand and effective supply of CR programmes. In case of no-referral due to logistic restraints, the document recommends the adoption of best alternatives to CR for disability reduction, better prognosis, and improvement of quality of life. The joint position paper is also aimed at promoting the consideration of Geriatric Medicine as a potential stakeholder of CR
