IMPEX: An Approach to Analyze Source Code Changes on Software Run Behavior  [PDF]
David Nemer
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.64020
Abstract:

The development of software nowadays is getting more complex due to the need to use software programs to accomplish more elaborated tasks. Developers may have a hard time knowing what could happen to the software when making changes. To support the developer in reducing the uncertainty of the impact on the software run behavior due to changes in the source code, this paper presents a tool called IMPEX which analyzes the differences in the source code and differences on the run behavior of two subsequent software versions, in the entire repository, demonstrating to the developer the impact that a change in the source code has had on the software run, over the whole software history. This impact helps the developers in knowing what is affected during execution due to their changes in the source code. This study verifies that the software runs that are most impacted by a given change in the source code, have higher chances in being impacted in the future whenever this part of the code is changed again. The approach taken in this paper was able to precisely predict what would be impacted on the software execution when a change in the source code was made in 70% of the cases.

Celebrities Acting up: A Speech Act Analysis in Tweets of Famous People  [PDF]
David Nemer
Social Networking (SN) , 2016, DOI: 10.4236/sn.2016.51001
Abstract: Twitter has become very popular among celebrities. It is the main platform used by them to publish press releases and, especially, to reach out to their fans. Given the pervasiveness of celebrities on the site, people with related interests may be especially likely to start using the service due to the perception of direct access to a famous person. As for the celebrities, it is a way of being close to the public and giving them an insight in to the life of a celebrity. Although most celebrity Twitter accounts are only used for promotion purposes, many celebrities use their personal accounts for the purpose of communicating with their fans, friends and other celebrities. These celebrities tweet personal photos and share their inner thoughts for various reasons and to different audiences. Thus in this study I ask: What are celebrity speech patterns on Twitter? Are they talking mostly to fans, and if not, who are they talking to? How are they talking to these different audiences? I address these questions by analyzing the tweets publicly available on four active celebrities’ Twitter timelines. The findings support that these celebrities indeed address different audiences on Twitter, including fans, friends, family and other celebrities. The findings further reveal that celebrities tend to communicate using different speech acts when talking to these different audiences. In light of this evidence, I attempt to highlight patterns that may be relevant with regards to the celebrities’ gender.
Genetic Insights into Bicuspid Aortic Valve Formation

Cardiology Research and Practice , 2012, DOI: 10.1155/2012/180297
Abstract: Bicuspid aortic valve (BAV) is the most common congenital heart defect, affecting 1-2% of the population. It is generally diagnosed late in adulthood when deterioration of the abnormal leaflet becomes clinically evident. BAV patients have an increased risk of developing serious complications, including stenosis, regurgitation, endocarditis, dilation of the aorta, aortic dissection, and aneurysm. BAV is a heritable trait, but the genetic basis underlying this cardiac malformation remains poorly understood. In the last decade, thanks to studies in animal models as well as genetic and biochemical approaches, a large number of genes that play important roles in heart development have been identified. These discoveries provided valuable insight into cardiac morphogenesis and uncovered congenital-heart-disease-causing genes. This paper will summarize the current knowledge of valve morphogenesis as well as our current understanding of the genetic pathways involved in BAV formation. The impact of these advances on human health including diagnosis of BAV and prevention of cardiovascular complications in individuals with BAV or with a family history of BAV is also discussed. 1. Overview of Valve Development In human and other mammals, cardiac valves are essential for unidirectional blood flow which is crucial for proper functioning and survival of the organism. Defects in valve structure or function can profoundly alter cardiovascular homeostasis and are among the leading causes of human morbidity and mortality. Thus, understanding the molecular basis of normal and pathologic valve development is of utmost importance and clinical relevance. The valves of the four chambered heart can be classified in 2 groups: atrioventricular valves (mitral and tricuspid) separate the atria from the ventricles while semilunar valves (aortic and pulmonary) divide the ventricles from the great arteries. Normal aortic valve is tricuspid, meaning it possesses three leaflets (or cusps) but defective development involving fusion of two of these produces bicuspid aortic valve (BAV). At 1-2% prevalence in the human population, BAV is the most common form of congenital heart disease and a significant risk factor for premature cardiovascular complications and valve replacement in young adults. In the embryo, the heart is the first organ to develop starting with the specification and migration of the anterior lateral plate mesoderm cells to form the cardiac crescent [1]. This is closely followed (embryonic day (E) 8.5 in the mouse and 3 weeks gestation in human) by migration of the cardiac
A fun o intertextual do cordel no cinema de Glauber Rocha

Sess?es do Imaginário , 2006,
Abstract: Este trabalho procura discutir o problema da intertextualidade fílmica por meio da análise da apropria o da literatura de cordel em "Deus e o diabo na terra do sol" (1963) e "O drag o da maldade contra o santo guerreiro" (1968), filmes de Glauber Rocha dedicados à representa o do universo social e cultural sertanejo. A quest o da forma da representa o, discutida nos seus textos "Estética da fome" (1965) e "Estética do sonho" (1971), reflete-se no modo como o cordel é tratado nestes dois filmes. This work discusses the problem of film intertextuality by the analisys of literatura de cordel appropriation in the films of Glauber Rocha where the sert o, its social and cultural universe, is focused: "Deus e o diabo na terra do sol" (1963) and "O drag o da maldade contra o santo guerreiro" (1968). The question of form representation, discussed in his texts "estética da fome" (1965) and "Estética do sonho" (1971), is reflected in the way the cordel is treated in these two films.

Abstract: objective: to identify the influence of alcohol intake on body adiposity of female college students. methods: female students attending the nutrition college course of universidade federal de ouro preto (mg, brazil) were the subjects of a transversal study. the pattern of alcohol consumption was evaluated by using the audit questionnaire and the adiposity was evaluated by body mass index, percentage body fat, waist circumference, arm circumference, triceps skin-fold thickness and waist-to-hip ratio. results: alcohol consumption was reported by 141 students. among them, harmful alcohol use (audit > 8) was reported by 56% (n = 79). mean values of percentage body fat, waist circumference and triceps skin-fold thickness were higher among students who reported any alcohol consumption (p < 0.05). values of arm circumference and triceps skin-fold thickness were increased among those with a drinking problem. there was a positive association between audit scores and parameters of body adiposity (percentage body fat, r = 0.20; p = 0.03); abdominal adiposity (waist circumference, r = 0.29; p = 0.01) and peripheral adiposity (arm circum-ference, r = 0.28; p = 0.02, and triceps skin-fold thickness, r = 0.23; p = 0.07). conclusion: alcohol consumption may have increased the body adiposity among students reporting alcohol intake. peripheral adiposity was higher among those in which this intake was harmful.
Familial Hypercholesterolemia: The Lipids or the Genes?

Nutrition & Metabolism , 2011, DOI: 10.1186/1743-7075-8-23
Abstract: In this review, we reconsider the clinical versus genetic nomenclature of FH in the literature. After we describe each of the genetic causes of FH, we summarize the known correlation with phenotypic measures so far for each genetic defect. We then discuss studies from different populations on the genetic and clinical diagnoses of FH to draw helpful conclusions on cost-effectiveness and suggestions for diagnosis.Familial Hypercholesterolemia (FH) (MIM #143890) is a genetic disease characterized by elevated LDL-Cholesterol (LDL-C), which deposits in the tissues causing the external manifestations of the disease, namely tendinous xanthomas, xanthelasmas, and corneal arcus. More importantly, LDL-C deposits in blood vessels leading to premature cardiovascular disease [1,2]. The patterns of inheritance of FH were first described by Khachadurian in Lebanon before the genes that contribute to the disease were known [3]. FH was defined as an autosomal dominant disease, with a clinical distinction based on phenotype severity of a "heterozygous" and a "homozygous" form, with serum LDL-C levels that are two times and four times the normal respectively [3]. The prevalence of the severe phenotype has been reported as 1 in a million in the general population, compared to the much more common mild form with a prevalence of 1 in 500 [1]. The prevalence has been reported to be ten times higher in certain populations with a presumed founder effect, such as the Lebanese, the French Canadians, and the South Afrikaners [1,2]. A less common autosomal recessive pattern of inheritance was also described in some of the initial Lebanese families [3].In 1986, the LDL receptor (LDLR) was discovered as the cause of Autosomal Dominant Hypercholesterolemia (ADH) [4]. It manifests a gene dosage effect such that the heterozygous and homozygous forms cause mild and severe phenotypes respectively. For years, ADH was thought of as a monogenetic disease. However, as more genotyping of FH patients was ca

Abstract: the objective of the present work is to revise and critically discuss the resilience concept defined as the capacity of psychological recovery of the human being before adversity, violence and catastrophes in life. in modern society, that changes faster and deeper, demanding constant adaptation efforts and, therefore turning the resilience into a challenge to the new millennium. the analyzed phenomenon lead to the conclusion that the resilience should not be part of a ideological conceptual group, on the contrary it rises from the sense that is attributed to the human existence, that is to say, for the capacity to make affective and professional liaisons and still for the existence of a life project.

Abstract: Este artigo tem por objetivo revisar e discutir criticamente o conceito de resiliência, definida como a capacidade que tem um ser humano de se recuperar psicologicamente, quando é submetido às adversidades, violências e catástrofes na vida. Na sociedade moderna as mudan as est o cada vez mais rápidas e profundas, exigindo constantes esfor os de adapta o e, portanto, tornando a resiliência um desafio ao novo milênio. A análise permitiu concluir que a resiliência n o deve pertencer a um grupo conceitual ideológico, ao contrário, advém do sentido que é atribuído à existência humana, ou seja, da capacidade de fazer la os afetivos e profissionais e ainda da presen a de um projeto de vida.
