Retraction Notice to “Challenges in the Prevention and Management of Adolescent Pregnancy and School Dropout by Adolescent Mothers in South Africa”
Full text linkThe following article published in 2024 (vol. 6, no: 1) in the Research in Educational Policy and Management (REPAM) has been retracted:
Twalo, T. (2024). Challenges in the Prevention and Management of Adolescent Pregnancy and School Dropout by Adolescent Mothers in South Africa. Research in Educational Policy and Management, 6(1), 180-196. https://doi.org/10.46303/repam.2024.12
Following concerns expressed by Commission of Gender Equality (CGE), which claimed that the article had drawn significantly from research conducted and published by the CGE without due permission or proper acknowledgment, the REPAM’s Editor-in-Chief conducted an internal investigation. The author was informed about the allegations and asked to provide an explanation. The investigation concluded that the CGE’s allegations were valid and that the article contained serious violations of research and publication ethics. As a result, the decision was made to retract the article. This decision has been taken in accordance with REPAM’s publishing ethics and the COPE guidelines on retractions. The author does not agree with the retraction.
The retracted article will remain online to maintain the scholarly record; however, it will be clearly marked as retracted
La red eclesial Pan-Amazónica -REPAM-: una apuesta de comunión por el cuidado de nuestra casa común
Full text linkEl presente artículo está basado en una serie de intervenciones recientes en espacios eclesiales y de la sociedad civil, como de algunos esbozos escritos, en los que se ha intentado posicionar la iniciativa de la naciente Red Eclesial Pan-Amazónica -REPAM-, partiendo de una perspectiva de territorialidad(es) que se construye desde una espiritualidad de la encarnación. En este sentido, la REPAM asume algunas de las pautas que nos propone la confrontadora e inspiradora Encíclica del Papa Francisco “Laudato Si”. Todo esto, en busca de generar reflexiones que permitan pensar algunas (otras) maneras de responder a los desafíos actuales que son ineludibles en todo sitio y para toda persona de nuestra casa común.
Retaguarda Emocional Para o Aluno de Medicina da Santa Casa de São Paulo (REPAM): realizações e reflexões
No full textEste artigo descreve a experiência de sete anos (1997-2003) do Repam - Retaguarda Emocional para o Aluno de Medicina da Faculdade de Ciências Médicas da Santa Casa de São Paulo -, enfocando especialmente os atendimentos psicoterápicos realizados. Relata o histórico do serviço, os profissionais que o compõem, seus objetivos e atividades desenvolvidas. Apresenta dados quantitativos e qualitativos sobre os atendimentos realizados, a partir de uma análise retrospectiva dos prontuários dos estudantes em psicoterapia durante esse período. Discute a experiência do Repam em relação a outros serviços com os mesmos objetivos, identificando semelhanças e especificidades. Finaliza com reflexões a respeito das vicissitudes deste tipo de trabalho, seus limites e potenciais
RepAM of the Amycolatopsis methanolica integrative element pMEA300 belongs to a novel class of replication initiator proteins
Full text linkAccessory genetic elements, such as plasmids and integrative elements, are widespread amongst actinomycetes, but little is known about their functions and mode of replication. The conjugative element pMEA300 from Amycolatopsis methanolica is present mostly in an integrated state at a single specific site in the chromosome, but it can also replicate autonomously. Complete nucleotide sequencing, in combination with deletion studies, has revealed that orfB of pMEA300 is essential for autonomous replication in its host. In this study, it was shown that purified OrfB protein binds specifically to the 39 end of its own coding sequence. Within this short sequence, a putative hairpin structure is located, which contains several direct and inverted repeats, and a nucleotide stretch that resembles the nicking site of the pC194 family of rolling circle replicating plasmids. Additional binding studies revealed that OrfB binds to an 8 bp inverted repeat that occurs three times within the hairpin structure. The data presented show that OrfB is the replication initiator (Rep) protein of pMEA300, and is therefore termed RepAM. Surprisingly, RepAM lacks significant sequence similarity with known prokaryotic Rep proteins, but it is highly similar to a number of yet uncharacterized ORFs that are located on integrative and conjugative elements of other actinomycetes. It is concluded that RepAM and its homologues are members of a novel class of Rep proteins.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
