HOUSING IN TURKEY - PROSPECTS FOR DIFFERENT INCOME GROUPS

It is imperative to develop a macro-level framework, and long-term policy alternatives to solve the housing problems of Turkey. Since most of the past housing programmes in Turkey were dependent on the estimation of housing needs, effective demand could not be properly evaluated. Yet, housing demand is closely connected with income level and ability to pay. So, effective housing programmes necessitate the predetermination of target groups, where income level and income share devoted to housing expenditures are considered. With this in mind, this study aims to compare alternative scenarios of housing finance considering their accessibility to different income groups. For this purpose, a macro-economic simulation model of housing needs assessment was utilised. Investment and subsidy requirements of the proposed housing programmes were also evaluated by using macro-economic data such as GDP growth rate, inflation and housing investment. As a result, it was concluded that current housing programmes are very far from meeting the demand of households. Comparison of four scenarios showed that new policy proposals should cover rental housing, especially for low income groups

Genomic analysis of Drosophila chromosome underreplication reveals a link between replication control and transcriptional territories

In Drosophila polytene chromosomes, most late-replicating regions remain underreplicated. A loss-of-function mutant of the suppressor of underreplication [Su(UR)] gene suppresses underreplication (UR), whereas extra copies of this gene enhance the level and number of regions showing UR. By combining DNA microarray analysis with manipulation of the number of Su(UR) gene copies, we achieved genomic-scale molecular identification of 1,036 genes that are arranged in clusters located in 52 UR chromosomal regions. These regions overlap extensively (96%) but are not completely identical with late-replicating regions of mitotically dividing Kc cells in culture. Reanalysis of published gene expression profiles revealed that genomic regions defined by replication properties include clusters of coordinately expressed genes. Genomic regions that are UR in polytene chromosomes and late replicated in Kc cell chromosomes show a particularly common association with transcriptional territories that are expressed in testis/males but not ovary/females or embryos. An attractive hypothesis for future testing is that factors involved in replication control, such as SU(UR), may interact physically with those involved in epigenetic silencing of transcription territories
