Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
A Profile of Fatherhood Among Young Men: Moving Away from Their Birth Family and Closer to Their Child.
No full textHave things changed all that much in terms of how fatherhood is conceptualized and exercised in daily life? That is the question underlying this article. The author compares the findings of a recent analysis on certain aspects of the lived experiences of young fathers (under 25 years of age) with the results of studies undertaken over the past ten years, and replies in the affirmative. First of all, when considering the representations held of fathers or mothers, most of these young fathers believe that their role is a multi-faceted one, and that it is often identical to that of their spouse. According to young fathers, fatherhood is a dual experience that requires them to be present on a daily basis while also casting their eye on the future. This is an experience that is constructed out of affectionate moments, child-care duties, education in the literal sense, and especially out of shared experiences with their spouse. In addition, they question the degree to which involvement in a career should take precedence over involvement in their child's life. In other words, the former 'competes' with their ability to be present in their child's daily life, which denotes a change from the attitudes of previous generations.Fatherhood, Young Fathers, Representation, Paternal Identity, Qualitative Research
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

A copolymer based on benzo[1,2-b:4,5-b ']dithiophene and quinoxaline derivative for photovoltaic application
No full text
A D-A-D copolymer (PBDTQx) with a bandgap of 1.78 eV, containing alkoxy-substituted benzo[1,2-b:4,5-b']dithiophene (BDT) as donor and quinoxaline derivative (Qx) as acceptor, was synthesized by Stille coupling reaction. In order to study the photovoltaic property of PBDTQx, polymer solar cells (PSCs) were fabricated with PBDTQx as the electron donor blended with [6,6]-phenyl-C61-butyric acid methyl ester (PC61 BM) as the electron acceptor. The power conversion efficiency (PCE) of PSC was 1.01% for an optimized PBDTQx: PC61 BM ratio of 1:5, under the illumination of AM 1.5, 100 mW/cm(2). The results indicated that PBDTQx was a promising donor candidate in the application of polymer solar cells. (C) 2012 Elsevier Ltd. All rights reserved.</p

Perspektif Sayyid Qu?b Tentang Isu Penjagaan Pandangan Berdasarkan Ayat 30-31 Surah Al-Nur: The Perspective of Sayyid Qu?b on The Issue of Lowering The Gaze Based on Quranic Verses 30-31 of Surah Al-Nur
No full textKupasan tentang menjaga pandangan dalam ayat 30-31 surah al-Nur kurang diperbincangkan secara maw??‘? atau tematik dalam kitab-kitab tafsir. Walau bagaimanapun kajian pensejarahan mendapati bahawa kitab tafsir F? ?il?l al-Qur’?n karangan Sayyid Qu?b adalah salah satu kitab tafsir terbaik yang ditulis berasaskan objektif surah. Justeru, penulisan ini dilakukan bertujuan mengkaji apakah pendapat dan perspektif Sayyid Qu?b tentang menjaga pandangan yang terdapat dalam surah al-Nur, ayat 30-31. Metode yang digunakan dalam penulisan ini ialah analisis kandungan terhadap kitab-kitab tafsir dan hadis serta kajian-kajian ilmiah seperti tesis, jurnal-jurnal dan kertas-kertas penyelidikan. Kajian mendapati bahawa tafsiran tentang menjaga pandangan telah dikupas dengan amat terperinci dalam kitab F? ?il?l al-Qur’?n. Selain daripada menjaga pandangan adalah langkah pencegahan daripada perlakuan zina, beliau telah mengaitkan kepentingan menjaga pandangan dengan suasana masyarakat yang bersih dengan mendedahkan teori Freud yang tidak mendatangkan sebarang manfaat malah boleh merosakkan masyarakat. Sayyid Qu?b juga menjelaskan beberapa hukum yang berkaitan dengan menjaga pandangan, kesan-kesan dan akibat daripada tidak menjaganya. Penulisan ini penting kerana dapat menzahirkan pemikiran Sayyid Qu?b mengenai isu penundukan pandangan yang kurang mendapat tumpuan dalam kalangan pengkaji terkini sekaligus membuktikan penguasaan Sayyid Qu?b dalam berbagai ilmu yang dapat membantu mentafsirkan al-Quran al-Karim.
There are few discussions about the Islamic etiquette lowering the gaze as stated in Surah An-Nur verse 30-31 by the Quranic interpretive books (tafsir) in thematic method (mawdu’i). However, the historiography discovered an influential Quranic interpretive manuscript, Fi Zilal al-Qur’an. It is the best Quranic revelatory reference that discussed the content of the Surah objectively. Therefore, this study aims to discover the author’s point of view about manners in lowering the gaze as stated in the Quran. The methodology of this study involves a content analysis of Quranic interpretive books, Hadith and reviews of existing studies from theses, journals, and research papers.Through the analysis, this study found an extensive detail that conversed the morals of lowering the gaze through the book of Fi Zilal al-Qur’an. The book expressed this manner as prevention steps towards unlawful sexual activity (zina). It also suggested this behavior able to regulate the society to become more courtesy. In contrast, the findings contradicted the Freud theory, which was found may harm the community. Sayyid Qu?b also highlighted a few Islamic laws related to the manner of lowering the gaze and the impacts of neglecting it. The author's perspective related to the issue was very significant. There are still limited numbers of discussions in the recent studies. Thus, the variety of knowledge by the author, Sayyid Qu?b proves the ability to enhance the interpretation in al-Qur’an al-Karim
