The Americanization of political campaigns, which are characterized by certain peculiarities, such as the personalization of politics, weakening of party organizations, wide use of media channels in the political marketing process, need for specialization, primacy of opinions over ideologies and conceptualization of citizens as policy consumers, is a by-product of these dramatic transformations. This paper aims to compare Forza Italia and the Young Party through the Americanization of political campaigns with special emphasis on the connection between the transformation of political campaigns and the crisis of representative democracy.Conference Object Simulacrum: Simulation Virtual Reality for Emergency Medical Intervention in Battle Field Conditions(CEUR-WS, 2018) Güleç, Ulaş; Güleç, U.; Gözcü, M.A.; Yılmaz, Murat; Doğan, S.; Meşurhan, N.; Yılmaz, M.; İşler, V.; Dinç, M.; Bilgisayar Mühendisliği; Yazılım MühendisliğiIn recent years, virtual reality technology has become one of the most effective tools used in the field of education due to its both hardware and software features. There are several studies in the literature that have been developed using the benefits of this technology in many different areas such as military, industrial, education, health and entertainment. This research aims to create a virtual reality based system that trains military personnel on emergency response techniques in the battle environment. In this project developed with respect to the requirements of the Turkish Armed Forces, HTC Vive, one of the most successful virtual helmets, has been used in order to increase the realism of this virtual environment where individuals learn first aid techniques or reinforce their knowledge. Participants who felt themselves in a war environment using this helmet had the opportunity to learn first aid techniques related to bullet injuries, limb ruptures and arm breaks, which are the most common forms of injury in war conditions. This developed environment has been tested by both first aid technicians and experts in the military field to take their opinions about the environment. According to the results obtained from these interviews, it was seen that the designed battle environment does not contain real life risks and it provides a continuous re-opportunity to the participants so that this environment can be a useful educational tool for increasing the knowledge levels and abilities of those who will work in this area.Article Citation - WoS: 7Citation - Scopus: 8Psychometric Properties of the Turkish Version of Cohen- Mansfield Agitation Inventory in Patients With Dementia(Gunes Kitabevi Ltd Sti, 2012) Baştuğ, Gülbahar; Ozel-Kizil, E. Tugba; Bastug, Gulbahar; Erdogan, Seyda; Sakarya, Direnc; Durmaz, Nazli; PsikolojiIntroduction: Cohen-Mansfield Agitation Inventory (CMAI) is frequently used in patients with dementia for the assessment of agitation severity. This instrument is especially used in research investigating the severity of behavioral symptoms and their treatment responses. In this study, psychometric properties of the Turkish version of CMAI were investigated in patients with dementia (n=52). Materials and Method: CMAI-Turkish version was applied by face-to-face interview to the caregivers of dementia patients who were admitted to a geriatric psychiatry outpatient clinic. For validity, the correlations between CMAI total scores and Neuropsychiatry Inventory (NPI) total and subscale scores were evaluated. For internal consistency, Cronbach alpha value of the items was calculated. Results: CMAI scores were significantly correlated with NPI scores and Cronbach alpha value of the scale was high (0.89). Conclusion: Turkish version of CMAI is a valid and reliable tool for the assessment of the frequency and severity of agitation behavior. Further studies might evaluate inter-rater reliability of the scale in inpatients with dementia.Conference Object Factors That Raise the Reality of the Virtual Office Environment Designed To Educate Software Development Processes(CEUR-WS, 2018) Güleç, Ulaş; Güleç, U.; Yılmaz, M.; Yılmaz, Murat; İşler, V.; Bilgisayar Mühendisliği; Yazılım MühendisliğiSoftware Development Virtual Reality (SDVR) is an interactive virtual reality (VR) experience based on the tasks of software development starting from requirement analysis through software testing. The SDVR experience transports participants to a virtual world of a software development organization where they experience development problems and conflicting situations. In SDVR, the participant takes on the role of a new software developer being recruited into software development firm who should work alongside with five virtual characters, played by artificial intelligence. The purpose of this study is to explain the properties of the virtual office environment where the participants can experience software development processes in real office conditions. In order for people to gain experience, the simulated software development process should include the atmosphere and dynamism of the actual office environment. For this reason, the factors affecting the atmosphere of the virtual office environment are presented in the light of the opinions of the experts working in the field of software engineering. According to the results of this study, it is revealed that such a virtual office environment is a useful tool that can be used in the training of individuals who will work in software development field.Article Citation - WoS: 2Citation - Scopus: 2Ber Anaylsis for Super Lorentz-Gaussian Laser Beams Propagating in Turbulent Media(Gazi Univ, Fac Engineering Architecture, 2013) Gokce, Muhsin C.; Gökçe, Muhsin Caner; Sari, Filiz; Ozek, Faruk; Elektronik ve Haberleşme MühendisliğiIn this work, BER-SNR variation of super Lorentz-Gaussian laser beam that propagating horizontally path in turbulent media is analyzed. Using scintillation index which is obtained by extented Huygens-Fresnel principle, BER - SNR value is calculated. Matlab program is used to show BER - SNR variation depending on link distance and beamwidth. To conclude, in short link range, super Lorentz-Gaussian beam is proven to be better link performance superior to commercially available Gaussian beam.Conference Object An Industrial Case Study To Improve the Onboaring Process in Software Management(CEUR-WS, 2017) Yılmaz, Murat; Yilmaz, M.; Güleç, Ulaş; Güleç, U.; O'Connor, R.V.; Clarke, P.; Tüzün, E.; Yazılım Mühendisliği; Bilgisayar MühendisliğiIn this study, we investigate expert information about software process known to experienced software developers and study how this is to be transferred to the newly recruited software developers. By this means, the developers who are recruited to a software project should understand better the software development organization and especially its social structure more effectively. Through this work, along with structural and algorithmic improvements of the software product, problems related to adaptation to team culture, adaptation to company culture, and adaptation to software development tools used are also investigated. This study aims to find the requirements in the market so that the recruitment processes can be explored using serious game mechanics. With the help of an industrial case study, we question the applicability a serious game for recruitment in the industry by improving the on-boarding process which has been identified as a problem for many software companies.Article Citation - WoS: 9Citation - Scopus: 10Effect of Use of Cu-Cr P/M Electrodes on Machining Performance of Electric Discharge Machining(Gazi Univ, Fac Engineering Architecture, 2015) Gulcan, Orhan; Çoğun, Can; Uslan, Ibrahim; Usta, Yusuf; Cogun, Can; Çoʇun, Can; Mekatronik MühendisliğiIn this study, the effect of use of Cu-Cr powder metal (P/M) electrodes on EDM performance outputs, namely material removal rate (MRR), electrode wear rate (EWR), mean and maximum roughness of machined surface (R-a and R-z) and workpiece surface recast layer thickness, was investigated experimentally. The Cu-Cr P/M electrodes produced at different mixing ratios, compacting pressures and sintering temperatures were used to machine SAE 1040 steel. The analyses performed have shown that the electrode material is deposited on to the work surface as a layer and the powder mixing ratio, the compaction pressure and sintering temperature affect the EDM performance outputs.Conference Object Augmented Reality Based Continuous Onboarding Framework(CEUR-WS, 2018) Yılmaz, Murat; Ohri, İ.; Öge, İ.; Orkun, B.; Yılmaz, M.; Tüzün, E.; Yazılım MühendisliğiHaving an efficient and effective onboarding process for a newcoing employee is a very important factor for the following work performance.
