    Strategies for the evolution of sex
    (American Institute of Physics Inc., 2001-12) Tüzel, Erkan; Sevim, Volkan; Erzan, Ayşe
    The maintenance of a macroscopic sexual population is addressed. As a scenario, the mechanism of random conversion to sex, in the presence of a constant rate of mutation is examined. This scenario is very closely related to "coevolution of cell senescence and diploid sexual reproduction in unicellular organisms." In this work, a "senescence clock" ticks off a finite lifetime for each bit string. Sexual reproduction resets the senescence of clock; unless this happens after a number of generations of cloning, the offspring stop dividing and die.

    Evolutionary route to diploidy and sex
    (National Academy of Sciences, 2001-11-20) Tüzel, Erkan; Sevim, Volkan; Erzan, Ayşe
    By using a bit-string model of evolution, we find a successful route to diploidy and sex in simple organisms. Allowing the sexually reproducing diploid individuals to also perform mitosis, as they do in a haploid-diploid cycle, leads to the complete takeover of the population by sexual diploids. This mechanism is so robust that even the accidental conversion and pairing of only two diploids give rise to a sexual population.

    First domino tile in the social innovation process: idea creation of university students
    (IEEE, 2016-09-08) Yıldırım, Nihan; Ansal, Hacer
    Interrelations between creativity, innovativeness and entrepreneurial skills of individuals have long been discussed in the literature. Due to the challenges regarding their measurement, most studies focused on the intentions rather than the outcomes. The idea generation that requires creativity is the first stage of social innovation. The young population's creative potentials in participating social innovation practices deserve a special attention as they play a critical role in the innovativeness and entrepreneurship of societies. This study aims to explore the factors that determine the creative intentions of university students that are important in generating social innovation projects. A structured survey based on the literature was conducted among 600 management and engineering students from 3 universities from the different percentiles of the Entrepreneurial and Innovative University Index for 2012 of the Turkish Ministry of Science, Industry and Technology. The survey included questions on the demographic characteristics, environmental factors, motivators, university/institutional context, perceptions and creative thinking attitudes. By conducting reliability and factor analysis, accuracy and validity of data is tested and the impact factors were identified. Findings reveal that visionary attitude, curiosity, exploration and learning, attitude for own creativity, self-esteem, perception about the learnability of creativity, university and social environment are components of creative thinking intentions of students and some of these factors vary by year of study and university.

    Türkiye’deki psikologların cinsiyete/toplumsal cinsiyete ilişkin söylemleri: nitel bir çalışma
    (Mehmet Akif Kara, 2021-06-30) Şah, Umut; Tekdemir, Göklem
    The aim of this study is to find out ‘interpretative repertoires’ used as discursive resources for sex/gender explanations of psychologists working in various fields in Turkey. Within the scope hereof, in-depth interviews were conducted with fourteen psychologists. Interviews were recorded and then transcribed. Interview texts were analyzed through discourse analysis. As a result of the analysis, four different interpretative repertoires were identified; dichotomy, feelings, nurture and difference. As to dichotomy repertoire, sex/gender is constructed within biology-society and woman-man dichotomies while it is defined as an individual and inner phenomenon in the feelings repertoire. When it comes to nurture repertoire, sex/gender is described as an identity acquired by nurturing processes while sexual differentiation is constructed as the source of difference and variety among people in difference repertoire. The results of the study manifest that the participants conceptualize sex/gender and sexuality within a dichotomous and essentialist framework to a large extent. The discourses of psychologists in Turkey have undergone some shifts in parallel with the transformations in Western psychology, however it is still possible to argue that essentialist, dichotomous and heteronormative assumptions on sex and sexuality keep forming their discourses to a certain extent in explicit or implicit ways. This is connected with the limited relation of (mainstream) psychology to other disciplines, critical and social constructionist perspectives, qualitative methodologies and activism as well as the fact that psychology in Turkey has mostly been imported from the West.
