Tanzimat'tan Cumhuriyet'e aydınlık bir yüz : Abdülhak Hâmit Tarhan
No full textCataloged from PDF version of article.Abdülhak Hamit Tarhan (1852-1937) is the author of a large and
comprehensive volume of works is one of the most prolific authors in Turkish
Literature whose works range from poetry to drama. It can be easily deducted
through a rough analysis concerning his works that the poet/author had endorsed the
works published within the framework of "project of civilization" and pro-reformist
movements which occurred along the period beginning from Tanzimat Era
(Administrative Reforms in 1839) including İstibdat Era (Oppression) and
Meşrutiyet Era (Constitutional Monarchy) till the Proclamation of Republic in 1923.
There is also a general agreement among the pundits of literature and scholars who
carried out researches regarding Abdülhak Hâmit Tarhan that he scrutinized the
"female problematic" in his drams and poems. Although Gündüz Akıncı strongly
argued that "Abdülhak Hâmit Tarhan is the first feminist author in Turkish
Literature", it is remarkable that no research has been carried out regarding this
aspect of the author so far. Within the framework of this study, Abdülhak Hâmit
Tarhan's perspective of female problematic, his propositions concerning the solutions
and his contributions to the Ottoman-Turkish Feminist Movement has been argued
by means of analyzing his drama works, memories and lettersDemircan, Aynu
Is demand for polluting goods manageable? an econometric study of car ownership and use in Mexico
No full textCharging for social marginal costs is efficient regardless of price elasticities, but the importance of getting prices"right"is greater the more manageable, or elastic, the demand. In efficient pollution control programs, options to make cars cleaner are combined optimally with demand conservation. The roles played by"cleaner cars"as compared with"fewer trips"are determined by empirical parameters: cheap, clean technologies would imply a great role for cleaner cars, while high demand elasticities lead to a greater role for demand reduction. In seminal research, evisence was found to support the hypothesis that demand for commodities such as gasoline should have lower price elasticities and higher income elasticities in developing than in industrial countries. The authors estimate a model of gasoline demand and car ownership in Mexico, using a panel of annual observations by state. Key features they introduce are instrumental variables on different data and the treatment of (1) possible dynamics, (2) measurement errors in the data, and (3) unobserved characteristics in individual states. They use tests of serial correlation in the residuals to model the dynamics properly. The resulting model is one of almost immediate adjustment, with a short-term price elasticity for gasoline close to the long-term estimate of -0.8. The model displays elasticities that are lower (for income) and higher (for price) than those hypothesized, and are within the range of elasticities found in industrial countries. Byproducts of the model: The elasticity of car purchases with respect to gasoline prices is positive. Scrappage decisions are affected by income and by car and gasoline prices. And these elasticities are not significantly different in the richer states. For policy purposes, these findings do not support"elasticity pessimism"The use of car services is sensitive to pricing, which suggests that consumers, for some of their demand, have reasonably good alternatives to car services. Consideration of external costs - such as accidents, congestion, air pollution, and road damage - thus involve considerable demand conservation.Inequality,Transport and Environment,Energy and Environment,Economic Theory&Research,Environmental Economics&Policies
Superluminal Pulse Propagation in a One-sided Nanomechanical Cavity System
No full textWe investigate the propagation of a pulse field in an optomechanical system.
We examine the question of advance of the pulse under the conditions of
electromagnetically induced transparency in the mechanical system contained in
a high quality cavity. We show that the group delay can be controlled by the
power of the coupling field. The time delay is negative which corresponds to
superluminal light when there is a strong coupling between the nano-oscillator
and the cavity.Comment: 10 pages, 4 figures, accepted by Acta Physica Polonica
Havaintoja inkluusion toteutumisesta päiväkodin arjessa Jatulin tarhan päiväkodissa
No full textPäiväkirjamuotoisen opinnäytetyön tavoitteena oli kehittää pedagogisen toiminnan kautta inkluusion toimivuutta sekä tuottaa ajankohtaista sekä omiin kokemuksiini perustuvaa materiaalia inkluusiosta varhaiskasvatuksen arjessa jo olemassa olevaan tietoperustaan nojaten. Tarkoituksena oli havainnoida inkluusion toteutumista Oulun kaupungin Jatulin tarhan päiväkodin lapsiryhmän arjessa. Tarkastelin inkluusiota neljästä ennalta valitusta teemasta käsin ja koostin opinnäytetyöni tekemiini havaintoihin. Opinnäytetyöni koostuu kahdesta osasta, teoria-osuudesta ja tekemistäni havainnoista.
Varhaiskasvatussuunnitelman perusteiden (2022) mukaan varhaiskasvatusta tulee toteuttaa ja arvioida inklusiivisten periaatteiden mukaisesti. Inkluusio on käsitteenä vielä varsin uusi ja ihmiset käsittävät sen monin eri tavoin. Jotta voimme yhdessä toteuttaa ja arvioida inklusiivista varhaiskasvatusta, tulee meidän ymmärtää mitä inkluusio tarkoittaa ja mitkä arvot ovat käsitteen takana.
Opinnäytetyön teoreettisen osion tarkoituksena on avata itse varhaiskasvatusta Suomessa sekä inkluusiota varhaiskasvatuksessa. Teoreettinen osuus käsittelee näiden kahden aiheen lisäksi tuen toteuttamista varhaiskasvatuksessa sekä osallisuutta, jotka olivat hyödyllistä tietopohjaa opinnäytetyötä varten.
Opinnäytetyötä varten olen hakenut hyväksytyn tutkimusluvan Oulun kaupungilta. Opinnäyte-työstä ei tunnisteta ketään yksittäisiä henkilöitä.The aim of the diary-based thesis was to observe the functionality of inclusion and to produce topical material on inclusion in the everyday life of early childhood education based on the existing theoretical framework. The purpose was to observe the visibility of inclusion in the everyday life of a group of children at Jatulin tarhan kindergarten in the city of Oulu. Inclusion was examined from the perspective of four pre-selected themes, and the thesis was compiled based on observations. The thesis consists of two parts, the theoretical part and the observations made.
According to the National Core Curriculum for Early Childhood Education and Care (2022), early childhood education and care must be implemented and evaluated in accordance with inclusive principles. Inclusion is still a new concept, and people perceive it in many ways. To implement and evaluate inclusive early childhood education together, we need to understand what inclusion means and what values are behind the concept.
The purpose of the theoretical part of the thesis is to open early childhood education itself in Finland and inclusion in early childhood education. In addition, the theoretical part deals with the essential additional topics of these two topics, which were a useful knowledge base for the thesis. For my thesis, the author has applied for an approved research permit from the City of Oulu. No individual persons were be identified in the thesis
Wave Pattern Produced By An Heat Source Movıng Wıth Constant Velocıty On The Top Of An Infınıte Plate
No full textTez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2002Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2002Lineer, izotropik elastisite teorisi çerçevesinde sonsuz metal tabaka üzerinde sabit hız ile ilerleyen ısısal kaynağın meydana getirdiği dalga paternleri hesaplandı. Başlangıç koşullarına bağlı olan geçici etkiler ve dalgaların sönümleri ihmal edildi. Eğer ısısal kaynağın gidiş hızı, yüzey dalgalarının hızından küçükse, dispersif bükülme dalgaları meydana gelir. Dalga boyu tabakanın kalınlığından çok büyükse, dispersif bükülme dalgalarının frekansı dalga sayısının karesiyle orantılıdır. Bunun sonucu olarak dalga tepesi, gidiş yönüyle 90 derece açı yapar. Bu sonuç, yukardaki şartların getirdiği kısıtlamalar dahilinde ısısal kaynağın gidiş hızından bağımsızdır.Within the frame of linear, isotropic elasticity theory the wave pattern produced by a heat source moving with constant velocity on the top of an infinite plate is computed. The transient effects associated with the initial conditions and the damping of the waves are neglected. If the travel speed of the heat source is smaller than the velocity of the surface waves, the dispersive flexural waves will be excited. The frequency of these waves is proportional to the square of the wave number if the wavelength is much larger than the thickness of the sheet. In this limiting case it is found that the crest of the waves makes 900 degrees with the travel direction and this result is independent of the travel speed as long as the parabolic approximation remains valid for the dispersion relation of flexural waves.Yüksek LisansM.Sc
Dispersion And Waveguiding Of Ultraslow Light In Atomic Bose-Einstein Condensates
No full textTez (Doktora) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2007Thesis (PhD) -- İstanbul Technical University, Institute of Science and Technology, 2007Bose-Einstein yoğuşuk maddesini uyumlu optik bilgi işlemleri için dinamik hafıza aleti olarak araştırdık. Özellikle, yoğuşuk maddede depolama zamanı içinde çok yavaş optik vurumlar(darbeler) analiz edildi. Yüksek dereceden dağınım özellikleri hesaba katarak yoğuşuk maddede optik darbelerin ilerlemesini modelledik. Bu çalışmada atomik sistemin konuma bağlı olarak değişen yoğunluğu, sıcaklık ve atomik çarpışmaların şiddetine göre değişen yoğunluk profili de dikkate alındı. Yapılan sayısal ve analitik hesaplar ile kısa darbenin genişlemesini sıcaklığa, konuma ve atomik çarpışmalara göre analiz ettik. Bir optik darbe yoğuşuk madde içinde rezonans frekansında elektromanyetik olarak indüklenmiş saydamlık etkisi ile çok yavaş ilerletilebilir. Hızı son derece yavaş olduğundan sistem optik bilgiyi saklama için kullanılabilir. Sınırlı parametreler için uyumlu optik bilgi hafıza kapasitesi bulundu. Radyal yöndeki yoğunluk profilini dikkate alan ve fiber optikte eğimli indeks fiber profili ile yoğuşuk maddenin kırılma indisini modelledik. Ayrıca madde içinde çok yavaş optik darbeler gözlendi. Bu da rezonans olmayan elektromanyetik olarak indüklenmiş saydamlık koşulları altında gerçekleşti. Yoğunlaşmış maddenin taşıyabileceği mod sayısını hem analitik hem de sayısal olarak irdeledik. Ayrıca optik vurumların Bose-Einstein yoğuşuk (BEY) maddesinde ilerlemesinde üç boyutlu etkileri ve optik modların sayısındaki bağ koşulları incelendi. Kırılma indisi arttırılması durumunda daha çok optik modun (BEY) maddesinde taşınabileceğini gösterdik. Mod sayısının sıcaklığa bağlı değişimini inceledik. Kuvantum uyumluluk sayesinde, deneysel parametreleri kullanarak mod sayısının kontrol edilebileceğini gösterdik. Ayrıca tek ve çok mod koşulları analitik olarak bulundu. Analitik sonuçlar, sayısal sonuçlarla kontrol edildi. Ek olarak, kısa optik darbelerin Bose-Einstein yoğuşuk maddesinde ilerlemesinde ikinci dereceden dağınım etkisini ve nonlineer optik Kerr etkisini inceledik. Kerr nonlineer katsayısının darbe genişliği olan darbe üzerinde etkisi incelendi.We investigate potential of atomic Bose-Einstein condensates as dynamic memory devices for coherent optical information processing. Specifically, the number of ultra-slow pulses that can be simultaneously present within the storage time in the condensate has been analyzed. By modelling short pulse propagation through the condensate, taking into account high-order dispersive properties, constraints on the information storage capacity has been discussed. The roles of temperature, spatial inhomogeneity, the interatomic interactions and the coupling laser on the pulse shape have been pointed out. For a restricted set of parameters, it has been found that coherent optical information storage capacity would be optimized. The conditions determining the number of optical modes that can be supported by an atomic Bose-Einstein condensate are also investigated. We investigate waveguiding of ultraslow light pulses in an atomic Bose-Einstein condensate. We show that under the conditions of off-resonant electromagnetically induced transparency, waveguiding with a few ultraslow modes can be realized. Analytical results for the single and two-mode conditions are found. We show that under the conditions of off-resonant electromagnetically induced transparency, waveguiding with a few ultraslow modes can be realized. Results of numerical simulations are compared with analytical calculations of the propagation constants for a parabolic-refractive index profile. Moreover, we examine short pulse propagation through the atomic Bose-Einstein condensates taking into account Kerr nonlinearity and second-order dispersive effect. The roles of Kerr nonlinearity on the pulse shape have been examined on pulse width with 0.01 .DoktoraPh
Rationing can backfire : the day without a car in Mexico City
No full textIn November 1989, Mexico City's administration imposed a regulation banning each car from driving on a specific day of the week. The regulation has been both popular and controversial. Some feel that it is a reasonable concession aimed at alleviating congestion and pollution problems. Others feel it is both inefficient and unfair: inefficient in the way most rationing systems are inefficent, and unfair in that it is costly to some and easily avoided or accommodated by others. Some feel that it may also be so inefficient that it is counterproductive. The authors found evidence to support that view. Many households bought an additional car to get additional driving permits, and the amount of driving increased. Greater use of old cars and increased weekend driving may have contributed to the disappointing results of Mexico's one-day ban on driving: high welfare costs and none of the intended benefits.Roads&Highways,Economic Theory&Research,Environmental Economics&Policies,Financial Crisis Management&Restructuring,Country Strategy&Performance,Economic Theory&Research,Environmental Economics&Policies,Roads&Highways,Financial Crisis Management&Restructuring,Transport and Environment
Foreign aid's impact on public spending
No full textUsing a model of aid fungibility, the authors examine the relationship between foreign aid and public spending. Based on a panel of cross-country and time-series data, their results show that roughly 75 cents of every dollar given in net development assistance goes to current spending and 25 cents to capital spending in the recipient countries. But concessionary loans - a component of development assistance - stimulate far more government spending. Their results also show that aid increases both public and private investment. To test aid fungibility across both public spending categories, they use a newly constructed data series on the net disbursement of concessionary loans. They find that concessionary loans given to the transport and communication sector are fully nonfungible. But loans to the energy sector are converted into fungible monies and part of the funds leak into transport and communications. Loans to agriculture and education are also fungible. There is no evidence of concessionary funds being diverted for military purposes. Their results show that total public spending in the health sector has no impact on reducing infant mortality, but concessionary loans to the health sector do. This finding leads the authors to conclude that linking foreign aid to an agreed-upon public spending program in areas critical to development might be an effective way to transfer resources to developing countries.Decentralization,Gender and Development,Development Economics&Aid Effectiveness,Public Sector Economics&Finance,Economic Theory&Research,Inequality,Development Economics&Aid Effectiveness,Public Sector Economics&Finance,National Governance,Economic Stabilization
Bose-Einstein Condensate in a Linear Trap with a Dimple Potential
No full textWe study Bose-Einstein condensation in a linear trap with a dimple potential where we model dimple potentials by Dirac delta function. Attractive and repulsive dimple potentials are taken into account. This model allows simple, explicit numerical and analytical investigations of noninteracting gases. Thus, the Schrodinger equation is used instead of the Gross-Pitaevski equation. We calculate the atomic density, the chemical potential, the critical temperature and the condensate fraction. The role of the relative depth of the dimple potential with respect to the linear trap in large condensate formation at enhanced temperatures is clearly revealed. Moreover, we also present a semi-classical method for calculating various quantities such as entropy analytically. Moreover, we compare the results of this paper with the results of a previous paper in which the harmonic trap with a dimple potential in 1D is investigated
Optomechanical cavity without a Stokes side-band
No full textWe investigate a theoretical demonstration of perfect frequency conversion in an optomechanical system in the weak coupling regime without a Stokes side-band. An optomechanical cavity illuminated by a weak probe field generates two side-modes, differentiating from the original signal by a phonon frequency. We report the presence of a special combination of parameters in the weak-coupling regime, where Stokes side-mode vanishes exactly. Only the anti-Stokes mode is observed with a few hundreds Hz spectral bandwidth of the probe field. Emergence of this special point is totally unrelated with the electromagnetically induced transparency (EIT) condition, where absorption (dip) cancellation is limited with the damping rate of the mechanical oscillator. Emergence is independent of the cavity type, i.e. single or double-sided, and takes place only for a single value of the effective coupling strength constant which is specific to the system parameters. At a specific effective coupling strength between the mirror and the cavity field, which can be tunable via the coupling field, only the anti-Stokes band is generated. At that specific coupling there appears no Stokes field. Hence, a filter, to eliminate the Stokes field, does not necessitate
