Citation expectations: are they realized? Study of the Matthew index for Russian papers published abroad
No full textWe consider the "Matthew effect" in the citation process which leads to reallocation (or misallocation) of the citations received by scientific papers within the same journals. The case when such reallocation correlates with a country where an author works is investigated. Russian papers in chemistry and physics published abroad were examined. We found that in both disciplines in about 60% of journals Russian papers are cited less than average ones. However, if we consider each discipline as a whole, citedness of a Russian paper in physics will be on the average level, while chemistry publications receive about 16% citations less than one may expect from the citedness of the journals where they appear. Moreover, Russian chemistry papers mostly become undercited in the leading journals of the field. Characteristics of a "Matthew index" indicator and its significance for scientometric studies are also discussed
Artful living and the eradication of worry in Søren Kierkegaard's interpretation of Matthew 6:24-34
No full textDanish thinker Søren Kierkegaard published fourteen discourses, across four collections, on Matthew 6:24-34. The repeated readings of the biblical text, whose themes include the choice between God and mammon, worry, what it means to consider the birds and lilies, and how to seek first the kingdom of God, converge with Kierkegaard’s interest in anxiety, despair, worry, subjectivity, indirect communication, choice, the moment, and life before God. Accordingly, the discourses make connections with his larger works, elucidate frequently explored Kierkegaardian themes in recent scholarship, and contribute to his critique of nineteenth-century Copenhagen. Additionally, the collections present an interpretation of each verse and phrase of Matthew’s text and, held up against modern Matthew scholarship, they correlate with and contribute to Sermon on the Mount and New Testament studies. Kierkegaard’s reading of Matthew also holds implications for the practice of biblical interpretation as it promotes the importance of awareness of sin, interestedness, and appropriation as central to proper reading. His emphasis on Christ as the primary exemplar of Matthew’s text adds an additional Christological element to his hermeneutic. Furthermore, the discourses serve as spiritual treatises which provide the reader with theological terminology to help confront the problem of worry and suffering. In light of a human being’s distinctiveness as imago Dei, Kierkegaard elucidates ways an individual may respond artfully to the ongoing possibility of worry, a possibility which the discourses connect with Christian anthropology and external labels associated with possessions and status. The Matthew 6 discourses intimate Kierkegaard’s sympathy with classic Christian spirituality and, in combination with the cultural-ecclesiastical critique, the creative exegesis, and the in-depth analysis of the cause of and cure for worry, his work emerges as an excellent example of spiritual theology
Matthew’s Emmanuel Messiah: a paradigm of presence for god's people
No full textThe motif of divine presence is a clear phenomenon within the Gospel of Matthew. The modern critical means for assessing the ancient biblical text have multiplied to the point, some claim, of disparity. This study employs both narrative and redaction criticism in an attempt to respond authentically to the structural, historical and theological dimensions of Matthew's Gospel. This study begins with the presumption of the wholeness and integrity of Matthew's narrative, and assumes the gospel story to have an inherently dramatic structure which invites readers to inhabit imaginatively its narrative world and respond to its call. But since we are concerned with the role of both reader and author, this study also assumes a text with an historical author and context. The introduction focuses on the meta-critical dilemma facing New Testament students - what is the text and how do we read it? - and seeks some balance in terms of Krieger's analogy of the text as both window and mirror. Proposed is a narrative reading of Matthew's presence motif alongside a redaction critical assessment of it. In Chapter 2 the elements of narrative theory are introduced and relevant terms defined: the structure of narrative, the function of the narrator, points of view. Chapter 3 becomes an exercise in narrative reading, with Matthew's presence motif providing the focus, and the implied reader’s interaction with the story being predominant in interpretation. Characters, rhetorical devices, and points of view are discussed, to understand the motif's development throughout the story's progress. The thrust of Chapter 4 is thereafter to examine divine presence as a dominant motif within Matthew's most important literary context: the Jewish scriptures. Here the primary paradigms of divine presence provided by the Patriarchs, the Sinai experience, and the Davidic-Zion traditions are assessed. Chapter 5 follows with a more detailed examination of the OT "I am with you/God is with us" formula and its µeo' vµwv/ηuwv language, so strongly connected to Matthew's presence motif. Chapters 6-8 build on these investigations with a closer analysis of the three critical "presence passages" of Mt 1:23. 18:20 and 28:20. The passages and their contexts are probed from a redaction critical perspective, guided by the narrative investigation of Chapter 3, and the background from Chapters 4 and 5.The three major "presence passages" examined in Chapters 6-8 are also complimented by a number of secondary issues: worship, wisdom, the Spirit and the poor in Matthew, and their relation to Jesus' divine presence. These are discussed in Chapter 9. Chapter 10 summarizes and looks briefly at some implications. Matthew' presence motif proves to be an important element of the Gospel’s rhetorical design, redactional strategy and Christology. The presence of Jesus, the Emmanuel Messiah, exhibited in his risen authority, becomes the focus of his people's hopes and experiences in the post-Easter world. What the presence of Yahweh was to his people. Jesus now provides in a new paradigm for his people - his followers, the little ones, the poor and the marginalized, from all nations

Methylation profiles at birth linked to early childhood obesity
No full textChildhood obesity represents a significant global health concern and identifying its risk factors is crucial for developing intervention programs. Many "omics" factors associated with the risk of developing obesity have been identified, including genomic, microbiomic, and epigenomic factors. Here, using a sample of 48 infants, we investigated how the methylation profiles in cord blood and placenta at birth were associated with weight outcomes (specifically, conditional weight gain, body mass index, and weight-for-length ratio) at age six months. We characterized genome-wide DNA methylation profiles using the Illumina Infinium MethylationEpic chip, and incorporated information on child and maternal health, and various environmental factors into the analysis. We used regression analysis to identify genes with methylation profiles most predictive of infant weight outcomes, finding a total of 23 relevant genes in cord blood and 10 in placenta. Notably, in cord blood, the methylation profiles of three genes (PLIN4, UBE2F, and PPP1R16B) were associated with all three weight outcomes, which are also associated with weight outcomes in an independent cohort suggesting a strong relationship with weight trajectories in the first six months after birth. Additionally, we developed a Methylation Risk Score (MRS) that could be used to identify children most at risk for developing childhood obesity. While many of the genes identified by our analysis have been associated with weight-related traits (e.g., glucose metabolism, BMI, or hip-to-waist ratio) in previous genome-wide association and variant studies, our analysis implicated several others, whose involvement in the obesity phenotype should be evaluated in future functional investigations
Modeling binder removal in ceramic compacts
No full textBinder is often added to ceramic systems to provide mechanical strength to the green bodies during processing. The binder removal sequence for an individual system is difficult to predict due to the thermal reaction and mass transport of the volatile products. The objective of this work is to use computational methods to predict the kinetics of binder removal as a function of composition, particle size, pore size and tortuosity, temperature, body size and shape, etc.. The model will be used to predict the composition, temperature, and pore pressure as a function of time, position within the body, and heating sequence parameters. This will provide the ability to predict optimum heating sequences that minimize processing time and energy input while avoiding harmful high internal pressures and temperatures. Since there are many binder systems in use, a few specific cases will be considered. TGA (thermogravimetric analysis) of binders will be used to measure kinetics parameters that are inputs for the computational model. A framework will be developed to assess the binder removal sequence for a binder and ceramic system. The input for the model, computed in COMSOL Multiphysics, will be determined through analysis of TGA weight loss data and green body characterization. A set of tools will be presented that assist in the fitting of the TGA data, including the binder degrading into multiple species, higher order reactions, parallel and series reactions, etc.. The use of these ideas and tools will allow the modeler to better predict the heating sequence required for a ceramic and binder system to successfully remove all binder material.M.S.Includes bibliographical referencesIncludes vitaby Matthew L.

Beauty for the Present: Mill, Arnold, Ruskin and Aesthetic Education
No full textThe present thesis examines the idea of aesthetic education of three eminent Victorians: John Stuart Mill, Matthew Arnold and John Ruskin. By focusing on the essence of what they meant with ‘the cultivation of the beautiful’ and, more importantly, the way their ideas of beauty informed their criticism of society, my study aims to contribute to our understanding of the idea of aesthetic education in the Victorian context and, further, to participate in a recent debate about the nature of beauty and aesthetic education.
Chapter One focuses on John Stuart Mill’s concept of ‘feeling’ in a series of essays. I will demonstrate how Mill’s idea of ‘aesthetic education’ was an ‘education of feelings,’ and moreover, how this idea was integrated into his literary criticism, his later critique of democratisation, his description of an ideal liberal society and even his own style of writing. Chapter Two contains a comparative study of Matthew Arnold and Friedrich Schiller. Through a rereading of Arnold, I will argue that his idea of aesthetic education is essentially Schillerian and that their resemblance consists primarily in their stress on the importance of aesthetic unity for modern life, which was becoming increasingly fragmentary and multitudinous. Chapter Three examines John Ruskin’s idea of aesthetic education and concentrates particularly on the cultivation of perception. Perception, as I shall show, was pivotal in Ruskin’s idea of aesthetic education. Just as what happened in Mill and Arnold, the emphasis on the education of seeing continued from his early writings well into his art and social criticisms. It not only differentiated him from his fellow art critics; the conviction that people should perceive with a pure heart also enabled him to link observation of artistic details with moral criticism of contemporary society and, thereby, to turn the cultivation of the beautiful into a moral-aesthetic experience
Microbial enrichment culture responsible for the complete oxidative biodegradation of 3‑Amino-1,2,4-triazol-5-one (ATO), the reduced daughter product of the insensitive munitions compound 3‑Nitro-1,2,4-triazol-5-one (NTO)
No full text3-Nitro-1,2,4-triazol-5-one (NTO) is one of the main ingredients of many insensitive munitions, which are being used as replacements for conventional explosives. As its use becomes widespread, more research is needed to assess its environmental fate. Previous studies have shown that NTO is biologically reduced to 3-amino-1,2,4-triazol-5-one (ATO). However, the final degradation products of ATO are still unknown. We have studied the aerobic degradation of ATO by enrichment cultures derived from the soil. After multiple transfers, ATO degradation was monitored in closed bottles through measurements of inorganic carbon and nitrogen species. The results indicate that the members of the enrichment culture utilize ATO as the sole source of carbon and nitrogen. As ATO was mineralized to CO₂, N₂, and NH₄⁺, microbial growth was observed in the culture. Co-substrates addition did not increase the ATO degradation rate. Quantitative polymerase chain reaction analysis revealed that the organisms that enriched using ATO as carbon and nitrogen source were Terrimonas spp., Ramlibacter-related spp., Mesorhizobium spp., Hydrogenophaga spp., Ralstonia spp., Pseudomonas spp., Ectothiorhodospiraceae, and Sphingopyxis. This is the first study to report the complete mineralization of ATO by soil microorganisms, expanding our understanding of natural attenuation and bioremediation of the explosive NTO.Journal ArticleFinal article publishe
Constructing a polygenic risk score for childhood obesity using functional data analysis
No full textObesity is a highly heritable condition that affects increasing numbers of adults and, concerningly, of children. However, only a small fraction of its heritability has been attributed to specific genetic variants. These variants are traditionally ascertained from genome-wide association studies (GWAS), which utilize samples with tens or hundreds of thousands of individuals for whom a single summary measurement (e.g., BMI) is collected. An alternative approach is to focus on a smaller, more deeply characterized sample in conjunction with advanced statistical models that leverage longitudinal phenotypes. Novel functional data analysis (FDA) techniques are used to capitalize on longitudinal growth information from a cohort of children between birth and three years of age. In an ultra-high dimensional setting, hundreds of thousands of single nucleotide polymorphisms (SNPs) are screened, and selected SNPs are used to construct two polygenic risk scores (PRS) for childhood obesity using a weighting approach that incorporates the dynamic and joint nature of SNP effects. These scores are significantly higher in children with (vs. without) rapid infant weight gain—a predictor of obesity later in life. Using two independent cohorts, it is shown that the genetic variants identified in very young children are also informative in older children and in adults, consistent with early childhood obesity being predictive of obesity later in life. In contrast, PRSs based on SNPs identified by adult obesity GWAS are not predictive of weight gain in the cohort of young children. This provides an example of a successful application of FDA to GWAS. This application is complemented with simulations establishing that a deeply characterized sample can be just as, if not more, effective than a comparable study with a cross-sectional response. Overall, it is demonstrated that a deep, statistically sophisticated characterization of a longitudinal phenotype can provide increased statistical power to studies with relatively small sample sizes; and shows how FDA approaches can be used as an alternative to the traditional GWAS
Asymptotic normality of the principal components of functional time series
No full textAbstract We establish the asymptotic normality of the sample principal components of functional stochastic processes under nonrestrictive assumptions which admit nonlinear functional time series models. We show that the aforementioned asymptotic depends only on the asymptotic normality of the sample covariance operator, and that the latter condition holds for weakly dependent functional time series which admit expansions as Bernoulli shifts. The weak dependence is quantified by the condition of L 4 -m-approximability which includes all functional time series models in practical use. We also demonstrate convergence of the cross covariance operators of the sample functional principal components to their counterparts in the normal limit
