The underestimated virtues of the two-sector AK model
No full textWe show that the two-sector version of the AK model proposed by Rebelo (1991) can be read as an endogenous growth extension of Greenwood, Hercowitz and Krusell (1997). By confining constant returns to capital to the investment goods sector, the model generates endogenously the secular downward trend of the relative price of equipment investment and the rising real investment rate observed in US NIPA data. Whereas Jones (1995) criticizes that the one-sector model fails to reconcile the empirical facts of trending real investment rates and stationary output growth, this incompatibility vanishes in the two-sector version. Finally, a simple technological shock can reproduce the ‘1974’ break in post World War II US data. Thus, AK-type endogenous growth models comply much better with empirical evidence, once they are augmented with a strictly concave consumption sector.AK model; embodiment; endogenous growth; obsolescence; ‘1974’

The Poverty of Linear Nations: Lessons from Taking an AK Model to the Data.
No full textThis paper takes an AK model to the PWT data. In the model, intratemporal and intertemporal shocks are reduced forms for different technologies, and determine the variation of the growth rate. Using the policy functions of the model we recover time series for the unobserved technology shock for a panel of countries. We can then evaluate both how well the model fits the data and what the contribution of the different shocks to the variation of growth rates is. We find that the data is largely inconsistent with the AK structure. However, we isolate what we believe are pervasive patterns in macroeconomic models: a negative correlation between intra and intertemporal shocks, and an ever increasing level of technology matched with ever cheaper consumption relative to investment.endogenous growth; technology shocks; investment shocks

Aydınlatma faktörünün değerlendirilmesi: Antalya Bilim Üniversitesi Güzel Sanatlar ve Mimarlık Fakültesi örneği
No full textArchitects face physical risks in office environments as well as in construction sites. Working
under conditions that do not comply with the physiological expectations that architects are
accustomed to during their student years can cause health problems later on. In this context, it
is evaluated within the scope of the study to examine occupational health and safety in studio
environments where students and academicians spend a long time in architecture faculties
through lighting conditions. In the studio environments that students are accustomed to in the
process of their education, lighting needs in 8 hours of education per day create situations that
cause discomfort with insufficient lighting, lack of daylight or lighting from the wrong angle
and position. The examination of the ambient conditions is evaluated as the number,
characteristics, adequacy and effects of lighting in the classrooms where academicians who
teach in the same environments with the students of the Faculty of Architecture. In this study,
the lighting factor, which is one of the physical risk factors of occupational health and safety, is
examined under 8 sub-headings. These are; lighting intensity, luminescence, reflectivity, direct
and indirect lighting, glare, color temperature of light, color reflectivity and daylight. With these
sub-headings, the evaluation of discomfort caused by lighting, solution suggestions and the
evaluation of classroom environments as an application are analyzed by considering the studio
classrooms (8), lecture hall and computer laboratory of Antalya Bilim University Faculty of
Fine Arts and Architecture. With the data obtained, it is aimed to determine the factors that will
create negativity during the education process, to create healthy environmental conditions, to
create a suitable working area for students and academicians by considering physical,
physiological and psychosocial effects.Mimarlar şantiye ortamlarında olduğu kadar ofis ortamlarında da fiziksel risklerle
karşılaşmaktadır. Mimarların öğrencilik zamanında alıştıkları fizyolojik beklentilere uymayan
koşullar altında çalışmaları daha sonraki zamanlarda sağlık problemi olarak karşılarına

The Localization of Ak and Kok Horde
No full textThe author addresses the issue of the correlation of the names Ak and Kok Horde with the western and eastern wings of Ulus Dzhuchi. The paper provides a historiography of the issue over the last 20 years. In addition, the work of 20th century scientists is also used. The main information about the Ak and Kok Horde in the sources is analysed. The author's interpretation of the significance of the dedicatory inscription in the Khosrow and Shirin poem is provided. The issue of the relationship between the terms Ak Horde and Golden Horde is addressed. As a result, the author concludes that in the works of G.A. Fedorov-Davydov and V.V. Trepavlov the errors of medieval sources were overcome, and the localization of the Ak and Kok Horde and the secondary division of the ulus into wings were suggested with substantiation. The available sources suggest that the Russian chronicles and a number of Oriental authors create a unified picture in understanding this issue, while the use of the Chingiz-nama does not correlate with earlier sources. On the basis of a detailed study of Tinibek's history, it is concluded that he was not the ruler of Sygnak and, therefore, his kingdom was the western ulus with its centre in Saray. This use of the term Ak Horde in the poem does not contradict the accepted version of Ak and Kok Horde’s localisation. As for the issue of the relationship between the terms ‘Golden’ and ‘White’ Horde, a number of modern studies allow for the identification of these concepts

Dynamics of Network Formation Processes in the Co-Author Model
No full textThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
Ak y la humanidad: Una obra bajo sospecha

O’odham Language Planning and Policy in the Ak-Chin Indian Community
No full textabstract: The Ak-Chin Indian Community is a small community in southern Arizona comprised of roughly one thousand O’odham. The indigenous language of Ak-Chin is the ’O’odham ñeo’okĭ, O’odham language, however in recent decades the number of speakers of this language have begun to sharply decline. Due to a variety of sociological factors in interacting with the dominant colonial society, the people of Ak-Chin have begun a shift toward the predominant use of English in daily affairs. The goal of this thesis is to investigate the societal factors that have led to the decline of the O’odham language in Ak-Chin and to examine language policy and planning principles and practices which may serve as examples for the Ak-Chin community to re-establish a strong connection to their heritage language.Dissertation/ThesisMasters Thesis American Indian Studies 201
