Publication Metadata only Age differences in privacy attitudes, literacy and privacy management on Facebook(Masarykova Univ, Fac Social Studies, 2016) N/A; N/A; N/A; Department of Psychology; Department of Media and Visual Arts; Kezer, Murat; Sevi, Barış; Cemalcılar, Zeynep; Baruh, Lemi; Master Student; Master Student; Faculty Member; Faculty Member; Department of Psychology; Department of Media and Visual Arts; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; 40374; 36113Privacy has been identified as a hot button issue in literature on Social Network Sites (SNSs). While considerable research has been conducted with teenagers and young adults, scant attention has been paid to differences among adult age groups regarding privacy management behavior. With a multidimensional approach to privacy attitudes, we investigate Facebook use, privacy attitudes, online privacy literacy, disclosure, and privacy protective behavior on Facebook across three adult age groups (18-40, 41-65, and 65+). The sample consisted of an online convenience sample of 518 adult Facebook users. Comparisons suggested that although age groups were comparable in terms of general Internet use and online privacy literacy, younger groups were more likely to use SNSs more frequently, use Facebook for social interaction purposes, and have larger networks. Also, younger adults were more likely to self-disclose and engage in privacy protective behaviors on Facebook. In terms of privacy attitudes, older age groups were more likely to be concerned about privacy of other individuals. In general, all dimensions of privacy attitudes (i.e., belief that privacy is a right, being concerned about one's privacy, belief that one's privacy is contingent on others, being concerned about protecting privacy of others) were positively correlated with engagement in privacy protective behavior on Facebook. A mediation model demonstrated that amount of disclosure mediated the relationship between age groups and privacy protective behavior on Facebook. Finally, ANCOVA suggested that the impact of privacy attitudes on privacy protective behavior was stronger among mature adults. Also, unlike older age groups, among young adults, considering privacy as a right or being concerned about privacy of other individuals had no impact on privacy protective behavior.Publication Metadata only Biased perceptions against female scientists affect intentions to get vaccinated for COVID-19(Sage Publications Ltd, 2022) Kuru, Ozan; Yıldırım, Kerem; N/A; Department of Media and Visual Arts; Department of Psychology; Department of International Relations; Doğan, İsminaz; Baruh, Lemi; Cemalcılar, Zeynep; Çarkoğlu, Ali; Master Student; Faculty Member; Faculty Member; Faculty Member; Department of Media and Visual Arts; Department of Psychology; Department of International Relations; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Administrative Sciences and Economics; N/A; 36113; 40374; 125588Based on role congruity theory, we investigated how gender bias may influence public attitudes toward the vaccine in Turkey. Using a between-subjects design, we tested whether an emphasis on the female versus the male scientist as the vaccine's inventor in a news story influenced attitudes about the BioNTech vaccine and vaccination intentions. Partly confirming role congruity theory, three-way interaction results from 665 participants demonstrated that among male participants with a stronger belief in traditional gender roles (compared to males with lower belief), the presence of the female inventor, either by herself or together with the male inventor, decreased the perceived efficacy and safety of the vaccine and reduced intentions to be vaccinated by the BioNTech vaccine. We did not observe such differences for women. These findings highlight how gender bias may influence individuals' information processing and decision making in a way that may have negative consequences for public health.Publication Metadata only Constructing the outbreak: epidemics in media and collective memory(Sage Publications Inc, 2022) N/A; N/A; Pothou, Eleni; PhD Student; Graduate School of Social Sciences and Humanities; N/AN/APublication Metadata only Disrupting the spectacle: the case of capul TV during and after Turkey's Gezi uprising(Univ Westminster Press, 2017) Department of Media and Visual Arts; N/A; Bulut, Ergin; Bal, Haluk Mert; Faculty Member; PhD Student; Department of Media and Visual Arts; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 219279; N/AN/APublication Metadata only Forming visual expressions with augmented fashion(Sage Publications Inc, 2017) Yilmaz, Sejda Inal; Can, Kemal; N/A; N/A; Department of Media and Visual Arts; Genç, Çağlar; Buruk, Oğuz Turan; Özcan, Oğuzhan; PhD Student; PhD Student; Faculty Member; Department of Media and Visual Arts; Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; 12532Wearable devices have a crucial impact on our bodies since they directly affect our appearance. However, wearable design practitioners focus more on the practical functionalities of the technology, leaving more investigation needed on what kind of visual expressions the technology might enable on wearable devices. With a critical approach on this functional perspective, the authors conducted a design workshop with fashion design and engineering students in which they first created art expressions and then wearable devices by using technological components. This practitioner's essay reflects on the resulting hands-on design experiences in new visual expressions that would not have been possible with just traditional materials.Publication Metadata only Isles of emotion: emotionally expressive social virtual spaces for reflection and communication(Association for Computing Machinery, 2021) Department of Media and Visual Arts; N/A; N/A; N/A; Yantaç, Asım Evren; Karaturhan, Pelin; Şemsioğlu, Sinem; Akbaş, Saliha; Faculty Member; PhD Student; PhD Student; PhD Student; Department of Media and Visual Arts; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 52621; N/A; N/A; N/AIt is common not be fully aware of our experience of emotions, and sometimes it is hard to communicate our emotions to others. Using design strategies derived from ambiguity and performativity, we came up with the concept of Isles of Emotion, customizable abstract virtual spaces that represent emotions. Considering remote communication as one of the potential use cases, we assessed this concept as an emotional reflection and communication tool via user studies conducted with 6 pairs of closely related people who have lived apart in the near past. During the studies participants created their own emotion islands using VR tools and visited their own and their pair's islands. We contribute to the existing literature by sharing resulting design insights on emotionally expressive social virtual spaces, commenting on the level of abstraction from and connections to the real-world, sharing and collaboration concerning the islands and their customizability.Publication Metadata only Microfluidic pulse shaping methods for molecular communications(Elsevier B.V., 2023) N/A; Department of Electrical and Electronics Engineering; N/A; N/A; Kuşcu, Murat; Kahvazi Zadeh, Maryam; Bolhassan, Iman Mokari; Faculty Member; Master Student; PhD Student; Department of Electrical and Electronics Engineering; College of Engineering; Graduate School of Sciences and Engineering; Graduate School of Sciences and Engineering; 316349; N/A; N/AMolecular Communication (MC) is a bio-inspired communication modality that utilizes chemical signals in the form of molecules to exchange information between spatially separated entities. Pulse shaping is an important process in all communication systems, as it modifies the waveform of transmitted signals to match the characteristics of the communication channel for reliable and high-speed information transfer. In MC systems, the unconventional architectures of components, such as transmitters and receivers, and the complex, nonlinear, and time-varying nature of MC channels make pulse shaping even more important. While several pulse shaping methods have been theoretically proposed for MC, their practicality and performance are still uncertain. Moreover, the majority of recently proposed experimental MC testbeds that rely on microfluidics technology lack the incorporation of programmable pulse shaping methods, which hinders the accurate evaluation of MC techniques in practical settings. To address the challenges associated with pulse shaping in microfluidic MC systems, we provide a comprehensive overview of practical microfluidic chemical waveform generation techniques that have been experimentally validated and whose architectures can inform the design of pulse shaping methods for microfluidic MC systems and testbeds. These techniques include those based on hydrodynamic and acoustofluidic force fields, as well as electrochemical reactions. We also discuss the fundamental working mechanisms and system architectures of these techniques, and compare their performances in terms of spatiotemporal resolution, selectivity, system complexity, and other performance metrics relevant to MC applications, as well as their feasibility for practical MC applications.Publication Metadata only Molecular communication transmitter architectures for the internet of bio-nano things(Institute of Electrical and Electronics Engineers Inc., 2022) Department of Electrical and Electronics Engineering; N/A; Akan, Özgür Barış; Civaş, Meltem; Faculty Member; PhD Student; Department of Electrical and Electronics Engineering; College of Engineering; Graduate School of Sciences and Engineering; 6647; N/AIn this study, we investigate the nanomaterial-based approach for developing practical molecular communication transmitters (MC-Txs) for the Internet of Bio-Nano Things (IoBNT) applications, which are expected to be unconventional in many aspects. In particular, we focus on the most pressing challenges for MC-Tx architectures, namely controlling information molecule release and molecule replenishment, together with other aspects, selective molecule release and molecule leakage mitigation. We discuss promising nanomaterials and also identify potential challenges and research directions.Publication Metadata only Narrow escape problem in synaptic molecular communications(Association for Computing Machinery, Inc, 2022) Koca, Çağlar; Department of Electrical and Electronics Engineering; N/A; Akan, Özgür Barış; Civaş, Meltem; Faculty Member; PhD Student; Department of Electrical and Electronics Engineering; College of Engineering; Graduate School of Sciences and Engineering; 6647; N/AThe narrow escape problem (NEP) is a well-known problem with many applications in cellular biology. It is especially important to understand synaptic molecular communications. Active regions of synapses, also known as apposition zones, are connected to synaptic cleft through narrow slits, from which neurotransmitters can escape to or return from the cleft into the apposition zones. While neurotransmitters leakage into the cleft might be desired for the reuptake process, escaping neurotransmitters might trigger an undesired, i.e., false-positive or action potential in the post-synaptic terminal. Obtaining analytic solutions to NEPs is very challenging due to its geometry dependency. Slight alterations in either or both shape or the size of the hole and the outer volume may cause drastic changes in the solution. Thus, we need a simulation-based approach to solve NEPs. However, NEP also requires the size of the hole to be much smaller than the dimensions of the volume. Combined with the requirement for Brownian motion, where the step size is much smaller than the dimensions of the volume, simulations can be prohibitively long, even for modern computers. Therefore, in this work, we suggest a simulation algorithm that simultaneously satisfies the NEP and Brownian motion simulation requirements. Our simulation framework can be used to quantify the neurotransmitter leakage within synaptic clefts.Publication Metadata only Press-party parallelism and polarization of news media during an election campaign: the case of the 2011 Turkish elections(Sage Publications Inc, 2014) Department of International Relations; Department of Media and Visual Arts; N/A; Çarkoğlu, Ali; Baruh, Lemi; Yıldırım, Kerem; Faculty Member; Faculty Member; PhD Student; Department of International Relations; Department of Media and Visual Arts; College of Administrative Sciences and Economics; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 125588; 36113; 272085The aim of this article is to examine press-party parallelism during the 2011 national elections in Turkey. The article reports findings from a content analysis of 9,127 news articles and editorial columns from fifteen newspapers regarding the trajectory of press-party parallelism over the course of the twelve-week national elections campaign period. We focus on two indicators of press-party parallelism: (1) respective "voice" given to the two leading parties, calculated as the ratio of news that quoted sources from the incumbent Adalet ve Kalkinma Partisi (AKP) to the leading opposition party Cumhuriyet Halk Partisi (CHP) and (2) news articles' tones toward AKP and CHP. The newspapers that were content analyzed were first categorized into three groups based on survey data regarding the voting intentions of their readers: (1) a group of "conservative" newspapers whose readers intended to vote primarily for AKP, (2) a group of "mainstream broadsheets," and (3) a group of "opposition" newspapers with a readership base intending to vote for CHP. The findings suggest that over the course of the election campaign, internal pluralism in both conservative and opposition papers declined in terms of voice given to respective parties and tone of news coverage.
