The Process of Urbanisation in Pakistan, 1951–81
Get PDFThe current level of urbanisation in Pakistan, approximately 33 percent in 1998, is not high by global standards. But it is commonly linked with unemployment, underemployment, shortage of housing, transport and other infrastructure like water supply and sewerage. Compared to other areas of population dynamics, such as fertility and mortality, studies in the field of urbanisation and internal migration in Pakistan are rather limited. During the last three decades hardly half a dozen studies could be added in the field of urbanisation. These studies are primarily based on data generated by the different censuses. After the 1979 Population Labour Force and Migration (PLM) Survey, no nationally representative survey addressing the issue of urbanisation and internal migration could be carried out. Even regional studies could not be conducted during the last two decades. The present study is designed to utilise the 1998 census data to investigate urban population growth, pace (or tempo) of urbanisation and components of urban growth for the period of 1981–98.
ARİF KAZVİNÎ’NİN SÜLEYMAN NAZİF KASİDESİ
No full textArif Qazvini, who is referred to as an Iranian national poet, had polemic against some of the Ottoman poets and intellectuals during both his years in Istanbul and after on. His 43-couplet qasida which he titled "Suleyman Nazif " is the best known of all. In essence, this qasida is a kind of debate and fight between Pan-Turkist and Pan-Iranist idea. Both Suleyman Nazif and Arif Qazvini adopted stand according to the political and social changes of their time and expressed their opinions by help of literature. However, they used a harsh and less than polite language toward each other. In this article, we attempt to study Arif Qazvini and his 43-couplet qasida which is a good example in terms of explaining role of literature in exploring nation-state notion in the first quarter of 1900's, and rivalry between the Ottoman and Iran at the time.İran Edebiyatında “Milli Şair” olarak anılan Arif Kazvini, özellikle İstanbul’da bulunduğu yıllarda ve sonrasında kimi Osmanlı edebiyatçı ve fikir adamları ile kalem kavgasına tutuşmuş, Osmanlı aleyhine şiirler yazmıştır. Bu şiirlerden en önemlisi Kazvini’nin Süleyman Nazif’e cevaben kaleme aldığı 43 beyitlik “Süleyman Nazif” adlı kasidedir. Bu kaside aslında Pantürkist-Paniranist söylem ve düşünce arasında cerayan etmiş bir münazara türüdür. Gerek Süleyman Nazif gerekse Arif Kazvini, dönemin sosyal ve siyasal gelişmelerine göre tavır alarak fikir ve düşüncelerini edebiyatın da yardımı ile beyan etmişlerdir ancak bu beyan esnasında karşı tarafı rencide edecek derecede ağır bir edebi üslup kullanmışlardır. Bu makalede 1900’lü yılların ilk çeyreğindeki ulus-devlet arayışlarında edebiyatın rolü ile Osmanlı-İran arasındaki rekabetin edebi yönüne örnek teşkil edecek 43 beyitlik sözkonusu kasideyi ve kasidenin sahibi Arif Kazvini’yi inceledik
KONSTRUKSI PASANGAN CALON DALAM PILGUB JATENG 2008 OLEH MEDIA MASSA (KASUS PEMBERITAAN JAWA POS RADAR SEMARANG DAN SUARA MERDEKA)
Get PDFPilgub Jateng 2008 adalah pemilihan kepala daerah langsung pertama yang
terjadi di Jawa Tengah. Ada lima pasangan yang mencalonkan diri sebagai
gubernur-wakil gubernur. Mereka adalah Bambang Sadono-M. Adnan (Partai
Golkar), Agus Soeyitno-Kholiq Arif (PKB), Sukawi Sutarip-Sudharto (Partai
Demokrat-PKS), Bibit Waluyo-Rustriningsih (PDI-P) dan HM. Tamzil-Rozaq
Rais (PPP-PAN). Mekanisme pemilihan langsung berakibat jarak antara pasangan
calon dengan pemilih menjadi semakin dekat sehingga setiap pasangan calon
dituntut untuk memanfaatkan media dalam membangun citra positif. Dalam hal
ini peran media sebagai sarana komunikasi politik menjadi cukup vital. Bagi
pasangan calon, media adalah sarana strategis untuk menyebarluaskan pesan
politik kepada khalayak. Media sebagai salah satu sumber informasi bagi
masyarakat harus mampu menjalankan fungsinya dengan baik dengan berpegang
pada netralitas. Namun, dalam operasionalnya media selalu dipengaruhi faktor
internal dan eksternal yang membuat mereka tidak dapat sepenuhnya objektif.
Media bukanlah institusi yang bebas nilai. Isi media tidaklah merefleksikan
realitas yang ada namun mengkonstruksikan serangkaian fakta yang terjadi.
Metode triangulasi digunakan untuk mengetahui bagaimana harian Jawa
Pos Radar Semarang dan Suara Merdeka mengkonstruksikan masing-masing
pasangan calon. Juga untuk mengetahui kecenderungan pemberitaan serta politik
redaksional masing-masing media. Objek penelitian yang dipilih adalah beritaberita
tentang pasangan calon di harian Jawa Pos Radar Semarang dan Suara
Merdeka pada halaman satu dan rubrik khusus selama 26 Maret-22 Juni 2008.
Hasil penelitian menunjukkan bahwa harian Jawa Pos Radar Semarang
berusaha responsif dengan isu-isu politik memberikan konstruksi yang favorable
kepada pasangan Agus Soeyitno-Kholiq Arif, Bibit Waluyo-Rustriningsih dan
HM. Tamzil-Rozaq Rais. Sebaliknya, mereka memberikan konstruksi
unfavorable kepada pasangan Bambang Sadono-M. Adnan dan Sukawi Sutarip-
Sudharto. Sedangkan Suara Merdeka memilih gaya pemberitaan yang aman dan
tidak tendesius kepada masing-masing pasangan calon. Hasilnya, mereka
cenderung mengkonstruksikan pasangan Bambang Sadono-M. Adnan, Bibit
Waluyo-Rustriningsih dan HM. Tamzil-Rozaq Rais dengan bingkai yang
favorable. Sedangkan pasangan Agus Soeyitno-Kholiq Arif dan Sukawi Sutarip-
Sudharto dalam bingkai unfavorable.

Electronic Braille Document Reader
No full textThis paper presents an investigation into developing a portable Braille device which would allow visually impaired individuals to read electronic documents by actuating Braille text on a finger. Braille books tend to be bulky in size due to the minimum size requirements for each Braille cell. E-books can be read in Braille using refreshable Braille displays connected to a computer. However, the refreshable Braille displays are expensive, bulky and are not portable. These factors restrict blind and visually impaired individuals from accessing much of the literature which is not available in Braille.
The proposed device overcomes the problem of carrying bulky Braille books by allowing multiple E-books to be saved in a portable memory device. Translating text to Braille pattern gives the blind access to non-Braille literature. The single Braille cell design reduces the bulk of the device allowing it to be portable and reducing the cost.
A prototype was developed to prove Braille could be read by actuating Braille characters on a finger. The device read text from an SD card, translated it into Braille characters and actuated the Braille pattern which blind volunteers were able to read.
The investigation confirmed the feasibility of the Electronic Braille document reader. It also proved the theory that Braille could be read from a single Braille cell by the patterns actuating on a finger instead of the finger sliding across an already formed Braille pattern
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Unsupervised shape clustering using diffusion map
Get PDFThe quotient space of all smooth and connected curves represented by a fixed number of boundary points is a finite-dimensional Riemannian manifold, also known as a shape manifold. This makes the preservation of locality a critically important issue when reducing the dimensionality of shapes on the manifold. We present a completely unsupervised clustering algorithm employing diffusion maps for locality-preserving embedding of shapes onto a much lower-dimensional space. The algorithm first obtains a non-linear low-dimensional embedding of shape context features of outer boundary contours of the shapes. Considering the embedded coordinates as a new minimalist representation of shapes, a clustering of shapes is obtained using a finite mixture model. The proposed clustering algorithm is computationally efficient, as it relies on clustering in a very lowdimensional space, and produces much improved results (88.6% for a 7-class dataset) as compared to clustering with conventional linear projections
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
