Publication Metadata only Acceptability, feasibility and potential of an intervention using secret Facebook groups to complement existing HIV prevention strategies among female sex workers in Cameroon, a randomized pilot study(Routledge Journals, Taylor & Francis Ltd, 2023) Vazquez Guillamet, Laia J.; Babey, Mary Mah; Njah, Mercy; Blake, Hassanatu; Jasani, Amy; Kyeng, Rahel; Hao, Jiaying; Long, Dustin; Tih, Pius; Turan, Janet M.; Khan, Eveline Mboh; Dionne, Jodie; Turan, Janet Molzan; School of MedicineThis randomized pilot project evaluated an intervention promoting health care literacy around HIV, pre-exposure prophylaxis (PrEP), and stigma reduction using private social media groups that complemented existing HIV prevention services among female sex workers (FSWs) in Cameroon. The intervention was 12 HIV and sexual health videos tailored to FSWs that were released over 8 weeks through a secret Facebook group platform. In-person surveys were administered before, after the intervention, and three months later. No HIV seroconversions were detected; all participants completed follow-up and agreed to recommend the intervention to a coworker. Although the intervention was assessed to be acceptable and feasible to implement, poor internet connectivity was a key barrier. In time-series analysis, the intervention group participants reported improved PrEP interest, PrEP knowledge, and condom use along with reduced PrEP and HIV-related stigma, but no impact on sex-work related stigma or social cohesion. Similar results occurred in the control group. Cross-contamination and small pilot study size might have hindered the ability to detect the differential impact of this intervention. As communications technology increases in Cameroon, it is essential to learn more about FSWs preferences on the use of social media platforms for HIV prevention strategies.Publication Metadata only A social history of late Ottoman women(Homer academic Publ House, 2014) N/A; Gümüş, Yeter Can; Master Student; Graduate School of Social Sciences and Humanities; N/AN/APublication Metadata only The first biallelic missense mutation in the fxn gene in a consanguineous turkish family with charcot-marie-tooth-like phenotype(2020) Candayan, Ayşe; Yunisova, Gülşhan; Çakar, Arman; Durmuş, Hacer; Parman, Yeşim; Battaloğlu, Esra; N/A; Başak, Ayşe Nazlı; Faculty Member; Koç University Research Center for Translational Medicine (KUTTAM) / Koç Üniversitesi Translasyonel Tıp Araştırma Merkezi (KUTTAM); School of Medicine; 1512Charcot-Marie-Tooth (CMT) disease is the most common inherited neuropathy with a prevalence of 1 in 2500 individuals worldwide. Here, we report three Turkish siblings from consanguineous parents presenting with a CMT-like phenotype who carry a homozygous c.493C>T, p.Arg165Cys mutation in the FXN gene that is the only known causative gene for Friedreich’s ataxia (FRDA). The identified missense mutation has been reported previously in two FRDA cases in compound heterozygosity with the common GAA repeat expansion in the first intron of the FXN gene. Analysis of skin biopsy samples from our family indicated that the mutation does not affect the expression levels of the frataxin, pointing to functional impairment of the corresponding protein. The CMT phenotype in the siblings was associated with visual impairment, optic nerve atrophy, and dysarthria. To the best of our knowledge, this family represents the first FXN missense mutation in homozygosity and challenges the notion that missense mutations have not been reported yet due to their embryonic lethality. Furthermore, this finding poses an interesting genetic overlap between autosomal recessive CMT and FRDA that we believe may have important implications on understanding the pathogenesis of these neurological disorders.Publication Metadata only Media in new Turkey: the origins of an authoritarian neoliberal state(Cambridge Univ Press, 2017) N/A; N/A; Müldür, Sezen Kayhan; PhD Student; Graduate School of Social Sciences and Humanities; N/AN/APublication Metadata only Living with hiv during COVID-19: knowledge and worry about COVID-19, adherence to COVID-19-related precautions, and hiv health outcomes(Taylor & Francis, 2023) Nemli, Salih Atakan; Yigit, Ibrahim; Agrali, Burcu; Gokengin, Deniz; Department of Psychology; Turan, Bülent; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 219712The COVID-19 pandemic has been profound impacts on mental and physical health of individuals with chronic diseases. Thus, it is important to understand the effects of the COVID-19 pandemic on people living with HIV. We aimed to assess the association between COVID-19-related knowledge and worry, HIV-related health practices and outcomes, and adherence to precautions related to COVID-19, and possible associations of these factors with HIV treatment outcomes (ART adherence and viral load). A cross-sectional survey was conducted between October 2020 and February 2021 among 291 PLWH at two large university hospital HIV clinics in Izmir, Turkey. Additionally, the most recent HIV-RNA load, CD4 count was recorded using medical records. Logistic regression analyses were performed to determine predictors of self-reported adherence to COVID-19-related precautions, ART adherence and undetectable viral load. COVID-19-related worry, COVID-19-related knowledge, and ART adherence were significant predictors of adherence to COVID-19-related precautions. Furthermore, adherence to COVID-19-related precautions was a significant predictor of both ART adherence and undetectable viral load. Findings provide a unique aspect of the interrelations of COVID and living with HIV. Since health behaviors and outcomes for COVID-19 and HIV seem to be interrelated, treatment practices and interventions that address these simultaneously may enhance their efficacy.Publication Metadata only The state of property development in Turkey: facts and comparisons(Cambridge University Press (CUP), 2016) Demiralp, Seda; Gümüş, İnci; Department of Economics; Demiralp, Selva; Faculty Member; Department of Economics; College of Administrative Sciences and Economics; 42533In this article, we investigate economic and political developments in Turkey's construction sector over the last decade and consider their implications. We find that during the first term of the government of the Justice and Development Party (Adalet ve Kalkinma Partisi, AKP), thanks to administrative and economic incentives, both private and public construction rose considerably. Despite the construction sector's contribution to growth, there is also evidence of a transfer from the industrial sector toward the construction sector, which led to significant decline in the trend growth of the industrial sector in the era prior to 2006. Such evidence disappears in the post-crisis period, when the growth of private construction slows. However, overcentralization, clientelism, an absence of transparency, and limitations on citizen participation in urban planning remain as problems that need to be addressed through urban reform.Publication Metadata only Universal semiconstant rebalanced portfolios(Wiley, 2011) Singer, Andrew C.; Department of Electrical and Electronics Engineering; Kozat, Süleyman Serdar; Faculty Member; Department of Electrical and Electronics Engineering; College of Engineering; 177972In this paper, we investigate investment strategies that can rebalance their target portfolio vectors at arbitrary investment periods. These strategies are called semiconstant rebalanced portfolios in Blum and Kalai and Helmbold et al. Unlike a constant rebalanced portfolio, which must rebalance at every investment interval, a semiconstant rebalanced portfolio rebalances its portfolio only on selected instants. Hence, a semiconstant rebalanced portfolio may avoid rebalancing if the transaction costs outweigh the benefits of rebalancing. In a competitive algorithm framework, we compete against all such semiconstant portfolios with an arbitrary number of rebalancings and corresponding rebalancing instants. We investigate this framework with and without transaction costs and demonstrate sequential portfolios that asymptotically achieve the wealth of the best semiconstant rebalanced portfolios whose number of rebalancings and instants of rebalancings are tuned to the individual sequence of price relatives.Publication Metadata only Weak convergence to a matrix stochastic integral with stable processes(Cambridge Univ Press, 1997) Department of Economics; Caner, Mehmet; Faculty Member; Department of Economics; College of Administrative Sciences and Economics; N/AThis paper generalizes the univariate results of Chan and Tran (1989, Econometric Theory 5, 354-362) and Phillips (1990, Econometric Theory 6, 44-62) to multivariate time series. We develop the limit theory for the least-squares estimate of a VAR(1) for a random walk with independent and identically distributed errors and for I(1) processes with weakly dependent errors whose distributions are in the domain of attraction of a stable law. The limit laws are represented by functionals of a stable process. A semiparametric correction is used in order to asymptotically eliminate the ''bias'' term in the limit law. These results are also an extension of the multivariate limit theory for square-integrable disturbances derived by Phillips and Durlauf (1986, Review of Economic Studies 53, 473-495). Potential applications include tests for multivariate unit roots and cointegration.Publication Metadata only Between Neo-Ottomanism and Ottomania: navigating state-led and popular cultural representations of the past(Cambridge Univ Press, 2017) Karakaya, Yağmur; Department of Sociology; Ergin, Murat; Faculty Member; Department of Sociology; College of Social Sciences and Humanities; 106427In contemporary Turkey, a growing interest in Ottoman history represents a change in both the official state discourse and popular culture. This nostalgia appropriates, reinterprets, decontextualizes, and juxtaposes formerly distinct symbols, ideas, objects, and histories in unprecedented ways. In this paper, we distinguish between state-led neo-Ottomanism and popular cultural Ottomania, focusing on the ways in which people in Turkey are interpellated by these two different yet interrelated discourses, depending on their social positions. As the boundary between highbrow and popular culture erodes, popular cultural representations come to reinterpret and rehabilitate the Ottoman past while also inventing new insecurities centering on historical truth. Utilizing in-depth interviews, we show that individuals juxtapose the popular television series Muhteem Yuzyl (The Magnificent Century) with what they deem proper history, in the process rendering popular culture a false version. We also identify four particular interpretive clusters among the consumers of Ottomania: for some, the Ottoman Empire was the epitome of tolerance, where different groups lived peacefully; for others, the imperial past represents Turkish and/or Islamic identities; and finally, critics see the empire as a burden on contemporary Turkey.Publication Metadata only Heritage and scent: research and exhibition of Istanbul's changing smellscapes(Routledge Journals, Taylor and Francis Ltd, 2017) Department of Archeology and History of Art; Department of Archeology and History of Art; Davis, Lauren Nicole; Şenocak, Lucienne; PhD Student; Faculty Member; Department of Archeology and History of Art; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 100679This paper examines heritage, and particularly intangible heritage, by concentrating on the experience of smell to explore a heritage site in Istanbul, Turkey: the Spice Market. Due to a restoration project, the site became the focus of the 2012 international workshop Urban Cultural Heritage and Creative Practice,' which aimed at documenting the existing and threatened scents of the marketplace. in 2016 a gallery exhibition, Scent and the City,' was created as part of an effort to raise awareness about how scent constitutes an important component of the heritage of place. after providing a brief overview of the marketplace's transformations since its construction in the seventeenthcentury, this paper covers various methods of scent research, including scent walks, mapping, oral history interviews, and artistic performances, and illustrates how the smellscapes of this historic, and now touristic, quarter of Istanbul are changing. By bringing a sensory approach to this important heritage site in Istanbul we demonstrate how an embodied approach, which forefronts scent as intangible heritage and a primary modality, can serve as a catalyst for individuals and communities to access their memories, emotions, and values and increase awareness of the role scent plays in defining locality.
