Census-to-School Method Estimated Catchment Areas and Mean Income
No full textThis dataset includes two sets of files: (1) the school-bg files contain the block groups assigned to each school (i.e. estimated catchment areas), as well as corresponding census tracts and enrollments, using the Census-to-School (CTS) Method described in Hashim, Laski, Kelley-Kemple (2023); (2) the school-level file contains estimates for school-level mean income and variance of income derived using publicly available data on school locations from the CCD, enrollments, and census data on the number of school aged children in each block group, and the proportion of families with school-age children in each income bin in each tract. See Hashim, Laski, Kelley-Kemple (2023) for details
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
2D simulation of transient enhanced boron out-diffusion from the base of a SiGe HBT due to an extrinsic base implant
No full textTransient enhanced diffusion of boron in SiGe HBTs is studied by comparing measurements of the temperature dependence of the collector current with the predictions of 2D process and device simulations. The collector current is chosen for modelling because it is extremely sensitive to very small amounts of out-diffusion from the SiGe base, and hence provides a rigorous test for the accuracy of the transient enhanced diffusion models. The SiGe HBT studied incorporates an ion implanted extrinsic base adjacent to the SiGe base, which allows the influence of the implantation damage on the boron diffusion to be studied. The process simulations show that point defects generated by the extrinsic base implant lead to a broadening of the basewidth around the perimeter of the emitter due to transient enhanced diffusion of boron from the SiGe base. This causes parasitic energy barriers to form, which in the worst case, extend laterally several microns from the edge of the extrinsic base. The electrical effect of the transient enhanced diffusion is a decrease in collector current as the emitter geometry is reduced. Transistors with different emitter geometries and undoped SiGe spacer thicknesses are studied and the collector/base reverse bias is varied to modulate the parasitic energy barrier at the collector/base junction. The trends in the measured collector current are in all cases well predicted by a simplified "plus one" transient enhanced diffusion model
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
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

Kepemimpinan Hashim Ibn ‘Abd Manaf Terhadap Bangsa Quraysh
No full textThis article discusses the figure of Hashim ibn ‘Abd Manaf as the leader of the Quraish nation. He is the ancestor of Rasulullah Saw, who was the first to open a new trade route outside the city of Mecca twice a year. By using literature research, this article finds historical information that the success of the Quraish nation was pioneered by one of the traders, who later became known as a leader and trading figure among them. Hashim ibn ‘Abd Manaf's character can be seen from his expertise in seeing opportunities to change the trade route (silk route) in the northern region, which was often disrupted by wars between Rome and PersIa. With his diplomatic techniques, Hashim ibn ‘Abd Manaf succeeded in proposing a change in the trade route from the north to the south that crossed Mecca. This path became known as the rihlat al-shita wa al-sayf path and was immortalized in the Koran with the revelation of the Quraish letter. The findings of this article provide an illustration that the success of a nation can be built through the nation's ability to seize opportunities. Hashim ibn 'Abd Manaf was a leader who was able to see these opportunities and apply them to leading the Quraish nation.
Artikel ini membahas tentang sosok Hashim ibn ‘Abd Manaf sebagai pemimpin bangsa Quraish. Ia adalah nenek moyang Rasulullah Saw, yang merupakan orang yang pertama kali membuka rute baru perjalanan dagang ke luar kota Makkah sebanyak dua kali dalam setahun. Dengan menggunakan studi pustaka, artikel ini menemukan informasi historis bahwa keberhasilan bangsa Quraish dipelopori oleh salah seorang pelaku dagang yang di kemudIan hari dikenal menjadi pemimpin dan tokoh dagang di kalangan mereka. Ketokohan Hashim ibn ‘Abd Manaf terlihat dari kepIawaIannya dalam melihat peluang perubahan jalur dagang (jalur sutera) wilayah utara yang seringkali terganggu oleh peperangan antara Romawi dan PersIa. Dengan teknik diplomasinya, Hashim ibn ‘Abd Manaf, berhasil mengusulkan perubahan jalur dagang wilayah utara ke wilayah selatan yang melintasi Makkah. Jalur ini kemudIan dikenal sebagai jalur rihlat al-shita wa al-sayf dan dIabadikan dalam al-Quran dengan diturunkannya surat Quraish. Temuan artikel ini memberikan gambaran bahwa keberhasilan suatu bangsa, dapat dibangun melalui kepIawaIan meraih peluang yang dilakukan oleh bangsa itu sendiri. Hashim ibn ‘Abd Manaf merupakan seorang pemimpin yang mampu melihat peluang tersebut dan menerapkannya dalam memimpin bangsa Quraish.
 
Narrazioni del soggetto in crisi: il "romanzo dialogato" Adib e il "romanzo-parabola" Qindil Umm Hashim
No full textIn questo capitolo (1.5) l'autrice analizza i due romanzi "Adib" di Taha Husayn e "Qindil Umm Hashim" di Yahya Haqqi i quali presentano delle storie di giovani "fuori stagione", ovvero due storie che si delineano come storie di formazione e trasformazione contrastate, indipendentemente dall'età anagrafica dei soggetti.
Nella prima si evidenzia una rottura del soggetto con le proprie radici e la "perdizione" di questo in Europa, nella seconda al contrario il soggetto, di ritorno dall'Europa, dopo una crisi profonda riesce a riconciliarsi con il suo ambiente d'origine
