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
The phytochrome-deficient pcd1 mutant of pea is unable to convert heme to biliverdin IXα
No full textWe isolated a new pea mutant that was selected on the basis of pale color and elongated internodes in a screen under white light. The mutant was designated pcd1 for phytochrome chromophore deficient. Light-grown pcd1 plants have yellow-green foliage with a reduced chlorophyll (Chl) content and an abnormally high Chl a/Chl b ratio. Etiolated pcd1 seedlings are developmentally insensitive to far-red light, show a reduced response to red light, and have no spectrophotometrically detectable phytochrome. The phytochrome A apoprotein is present at the wild-type level in etiolated pcd1 seedlings but is not depleted by red light treatment. Crude phytochrome preparations from etiolated pcd1 tissue also lack spectral activity but can be assembled with phycocyanobilin, an analog of the endogenous phytochrome chromophore phytochromobilin, to yield a difference spectrum characteristic of an apophytochrome-phycocyanobilin adduct. These results indicate that the pcd1-conferred phenotype results from a deficiency in phytochrome chromophore synthesis. Furthermore, etioplast preparations from pcd1 seedlings can metabolize biliverdin (BV) IXα but not heme to phytochromobilin, indicating that pcd1 plants are severely impaired in their ability to convert heme to BV IXα. This provides clear evidence that the conversion of heme to BV IXα is an enzymatic process in higher plants and that it is required for synthesis of the phytochrome chromophore and hence for normal photomorphogenesis.</p
The phytochrome-deficient pcd2 mutant of pea is unable to convert biliverdin IXalpha to 3(Z)-phytochromobilin
No full textDuring screening of ethylmethane sulphonate-mutagenized pea (Pisum sativum L.) seedlings under far-red light a mutant line, AF130, was isolated which showed a reduction in both red and far-red light-induced de-etiolation responses. The photomorphogenic phenotype of AF130 results from a single recessive mutation which is not allelic with the previously described phytochrome chromophore biosynthesis mutant pcd1. This new mutant has been designated pcd2, for phytochrome chromophore deficient 2. Like pcd1, etiolated pcd2 seedlings are severely deficient in spectrally active phytochrome and contain wild-type levels of phytochrome A apoprotein which is not substantially depleted by red light treatment. Etioplast preparations from pcd2 seedlings can metabolize heme to biliverdin (BV) IX?, but are unable to convert BV IX? to the phytochrome chromophore, phytochromobilin. The PCD1 and PCD2 genes therefore control consecutive steps in phytochromobilin synthesis. Despite a similarly severe impairment of photomorphogenic responses, pcd2 mutant seedlings do not display the strongly chlorotic phenotype of pcd1, suggesting that this characteristic of pcd1 does not result from phytochrome deficiency per se, but is a specific effect of the pcd1 mutation. A double mutant between pcd1 and pcd2 was constructed. This mutant is paler than pcd1 and less responsive to red light than either single mutant, but retains a strong response to blue light.<br/
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

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

Diffusion-weighted (DW) MRI in lung cancers: ADC test-retest repeatability
No full textPurpose:
To determine the test-retest repeatability of Apparent Diffusion Coefficient (ADC) measurements across institutions and MRI vendors, plus investigate the effect of post-processing methodology on measurement precision.
//
Methods:
Thirty malignant lung lesions >2 cm in size (23 patients) were scanned on two occasions, using echo-planar-Diffusion-Weighted (DW)-MRI to derive whole-tumour ADC (b = 100, 500 and 800smm-2). Scanning was performed at 4 institutions (3 MRI vendors). Whole-tumour volumes-of-interest were copied from first visit onto second visit images and from one post-processing platform to an open-source platform, to assess ADC repeatability and cross-platform reproducibility. //
Results:
Whole-tumour ADC values ranged from 0.66-1.94x10-3mm2s-1 (mean = 1.14). Within-patient coefficient-of-variation (wCV) was 7.1% (95% CI 5.7–9.6%), limits-of-agreement (LoA) -18.0 to 21.9%. Lesions >3 cm had improved repeatability: wCV 3.9% (95% CI 2.9–5.9%); and LoA -10.2 to 11.4%. Variability for lesions <3 cm was 2.46 times higher. ADC reproducibility across different post-processing platforms was excellent: Pearson’s R2 = 0.99; CoV 2.8% (95% CI 2.3-3.4%); and LoA -7.4 to 8.0%. //
Conclusion:
A free-breathing DW-MRI protocol for imaging malignant lung tumours achieved satisfactory within-patient repeatability and was robust to changes in post-processing software, justifying its use in multi-centre trials. For response evaluation in individual patients, a change in ADC >21.9% will reflect treatment-related change
