Tamar's cry : re-reading an ancient text in the midst of a contemporary pandemic
Get PDFCITATION: Ackermann, D. M. 2004. Tamar's cry : re-reading an ancient text in the midst of a contemporary pandemic. Nederduitse Gereformeerde Teologiese Tydskrif, 45(2), doi:10.17570/ngtt.2004.v45s1.a13.The original publication is available at https://ojs.reformedjournals.co.zaIn a first section, the story of Tamar is read from a woman's perspective, in a meditative, literary and canonical manner. In a second section, and against the backdrop of seeing HIV and AIDS in South Africa as “a gendered pandemic,†theological reflections are suggested that could contribute in the search for resistance and hope in the face of this bleak reality.https://ojs.reformedjournals.co.za/ngtt/article/view/317Publisher's versio
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
[Hypercalcemia in sarcoidosis--case report, prevalence, pathophysiology and therapeutic options]
No full textHypercalcemia is a highly prevalent complication of sarcoidosis. A medical history of a patient with sarcoidosis is shown as case report. Depending on the population studied about 2-63% of sarcoidosis patients show hypercalcemia. The major difference in the prevalence of hypercalcemia may be in part due to the undulating course of subacute sarcoidosis, so hypercalcemia may be missed when serum calcium is not frequently measured. Hypercalciuria appears to be twice as prevalent then hypercalcemia and should be looked for in every sarcoidosis patient. Hypercalcemia in sarcoidosis is due to the uncontrolled synthesis of 1,25-dihydroxyvitamin D3 by macrophages. 1,25-dihydroxyvitamin D3 leads to an increased absorption of calcium in the intestine and to an increased resorption of calcium in the bone. Immunoregulatory properties have been ascribed to 1,25-dihydroxyvitamin D3. It is an important inhibitor of interleukin-2 and of interferon-gamma-synthesis, two cytokines that are important in granuloma formation in sarcoidosis. It is thought that 1,25-dihydroxyvitamin D3 counterregulates uncontrolled granuloma formation. Treatment of hypercalcemia depends on the serum level of hypercalcemia and its persistence. Generally sarcoidotic patients should be advised to avoid sun exposition to reduce vitamin D3 synthesis in the skin, to omit fish oils that are rich of vitamin D and to produce more than two liters urine a day by adapting fluid intake. Although severe hypercalcemia seems to be rare, glucocorticosteroid treatment should be started if corrected total calcium level rises beyond 3 mmol/l. If hypercalcemia is symptomatic, treatment should be started even at lower levels. Glucocorticosteroids act by inhibition of the overly 1alpha-hydroxylase activity of macrophages. Alternatively, treatment with chloroquine or ketoconazole can be established. If isolated hypercalciuria without hypercalcemia is present with evidence for recurrent nephrolithiasis, patients can be treated with a thiazide diuretic
Rosemary Radford Ruether : themes from a feminist liberation story
Get PDFCITATION: Ackermann, D. M. 2008. Rosemary Radford Ruether : themes from a feminist liberation story. Scriptura, 97:37-46, doi:10.7833/97-0-712.The original publication is available at http://scriptura.journals.ac.zaAs one of the earliest and most influential feminist liberation theologians, Rosemary Radford Ruether's oeuvre has enabled many women theologians in different contexts and cultures to cover new ground by drawing on her insights. This article is a tribute to her ground-breaking work and her far ranging interests, all under girded by her passion for justice. In order to tell aspects of her theological story, three themes are dealt with : Feminist theology according to Ruether, feminist theological methodology, and church and ministry. In conclusion, a brief assessment of her work is made with particular reference to the categories of experience, the prophetic-liberating tradition and issues of gender race and ecumenismhttp://scriptura.journals.ac.za/pub/article/view/712Publisher's versio
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The mystery of hope : a response to the tragic
Get PDFCITATION: Ackermann, D. M. 2014. The mystery of hope: a response to the tragic. Nederduitse Gereformeerde Teologiese Tydskrif, 55(1): 1025-1034, doi:10.5952/55-Supp%201-683.The original publication is available at http://ojs.reformedjournals.co.zaThe tragic is undeniable and pervasive in our world. Our responses to it differ, ranging from despair, anger and disillusionment to hope that arises in the human spirit, despite tragic circumstances. This paper begins by looking briefly at the tragic, followed by a discussion of the elusive nature of hope that emerges in situations of suffering and adversity. The last section suggests that attempting to understand the mystery of hope in such circumstances entails embracing mystery as integral to religious experience. Finally, consideration is given to prayers of lament that name the suffering, followed by the willingness to wait in silence upon a possible encounter with the Holy One that will speak into situations otherwise inexplicable.http://ojs.reformedjournals.co.za/index.php/ngtt/article/view/429Publisher's versio
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
