    (Sage Publications inc, 2020) Akkoca, Ozlem; Unlu, Ceren Ersoz; Tatar, Ilkan; Sargon, Mustafa Fevzi; Zeybek, Dilara; Oguztuzun, Serpil
    Introduction: Smoking is a public health problem that has been proven to have adverse effects on human health. Aerobic exercise has positive effects on the human body, especially on the respiratory system. Objective: The aim of this experimental animal model study was to determine whether regular aerobic exercise has a protective effect against the harmful effects of cigarette smoke on the nasal mucosa of rats. Methods: A total of 24 male Wistar albino rats were randomly separated into 3 groups of 8: group 1 (cigarette smoking), group 2 (cigarette smoking and exercise), and group 3 (control group). At the end of the experiment period, histopathological (light and electron microscopy) and immunohistochemical (GSTA 1, CYP1A1, and CYP2E1) evaluations were made of the nasal mucosa of the animals. Results: Goblet cell loss and basal membrane thickening were significantly lower in group 2 and group 3 compared to group 1. In the electron microscope evaluation, the inflammatory expressions of the goblet cells were observed in a very small area in group 2. In group 1, these were distributed over large areas between the mucosal cells. There was seen to be significant swelling of the mitochondria in group 1 compared to the other groups. No statistically significant difference was determined between the groups with respect to GSTA1, CYP2E1, and CYP1A1 scores (P> .05). Conclusion: The results of this study showed that regular aerobic exercise has a protective effect against the harmful effects of smoking on the nasal mucosa of rats.

    The Rising Mafioso Capitalists, Opportunities, and the Case of Turkey
    (Sage Publications inc, 2011) Selcuk, Fatma Ulku
    This article attempts to examine the mafiosi's potential economic and political power with the help of two analytical tools: the mafioso mode of production, and mafioso capitalists. In evaluating the actual power of the mafiosi, the article presents empirical information on Turkey and other countries. It acknowledges that although the mafioso (capitalist) bosses hold the direct command of armed power, neither their antagonism nor their alliance with the conventional bourgeoisie can be essentialised. The results and prospects are evaluated in a way that stresses the need for a change in our worldviews in order to construct a more compassionate world.

    The Effect of Training, Used-Hand, and Experience on Endoscopic Surgery Skills in an Educational Computer-Based Simulation Environment (ece) for Endoneurosurgery Training
    (Sage Publications inc, 2019) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Isikay, Ilkay; Hanalioglu, Sahin; Suslu, Ahmet E.; Yucel, Taskin; Berker, Mustafa
    Today, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.

    Adult Education as a Stepping-Stone To Better Jobs: an Analysis of the Adult Education Survey in Turkey
    (Sage Publications inc, 2018) Cilasun, Seyit Mumin; Demir-Seker, Sirma; Dincer, N. Nergiz; Tekin-Koru, Ayca
    The objective of this article is to investigate whether adult education (AE) can be used as a tool in facilitating transitions to/in the labor market, using the cross-sectional Adult Education Survey of Turkey (2012). AE is defined as the nonformal education for individuals aged older than 25 years. The outcome of AE is measured by changing jobs for employed and finding a job for the unemployed. Concentrating on employed people, we analyze both the determinants and the outcome of participation in AE for the purpose of changing jobs; and second, concentrating on unemployed people, we analyze both the determinants and the outcome of participation in AE for the purpose of getting employed. We find that once young males who are already working participate in AE for changing work, independent of their education or how AE is financed, they can be successful in doing so. The results of the paper suggest that AE programs offered by the government can serve as a tool in increasing income of the less educated and the unemployed by facilitating their transition to the labor market.

    The Making of a gecekondulu Identity: Journalistic Representations of the Squatters in Turkey in the 1970s
    (Sage Publications inc, 2014) Avci, Ozgur
    While many studies have undertaken analyses of the socioeconomic and political problems resulting from rural-urban migration in developing nations, few have examined the symbolic challenges presented by this shift. Examining news reports on the most sensational instance of slum demolitions in Turkey that took place in 1977, this study argues that urban squatting and slum dwelling created vital problems of cultural representation. In spite of huge ideological differences among various newspapers, there was a surprising level of consistency in the portrayal of the squatters as a dubious group, devoid of ideological commitment, and a serious threat to society. Such a portrayal of the urban poor as nonideological actors has been dominant worldwide, which overlooks the powerful symbolic challenge that the very existence of this group poses to idealized projects of social change, and hence the potential that their despised (non)identity offers for the development of a more democratic political vision.

    Parametric Analysis of Viscoelastic Hyperboloidal Helical Rod
    (Sage Publications inc, 2016) Ermis, M.; Eratli, N.; Argeso, H.; Kutlu, A.; Omurtag, M. H.
    The objective of this study is to perform a pioneering research about a viscoelastic hyperboloidal helical rod having a standard type of distortional behavior and a Kelvin type of bulk compressibility. Field equations are based on the Timoshenko beam theory, and the exact curvatures of the hyperboloidal geometry are considered through the formulation. The numerical analysis is carried out by the mixed finite element method, considering the rotary inertia, in the Laplace space, and the results are transformed back to time space numerically using the modified Durbin's algorithm. A cantilevered hyperboloidal helical rod having solid circular, hollow circular, and thin-walled hollow circular cross sections is handled, and the rod is loaded by rectangular and triangular impulsive types of point load at the tip. Through the analysis, different values of retardation time, three different relaxation functions associated with shear modulus, and three different creep functions associated with bulk modulus are handled. Finally, a benchmark example is presented, and the influence of the loading and the material parameters on the helix geometry is discussed.

    Partner Phubbing and Sleep Quality: Serial Mediation Models With Relationship Satisfaction and Perceived Stress
    (Sage Publications inc, 2024) Dikdere, Busra; Turkarslan, Kutlu Kagan
    The increasing integration of technology into our lives has been affecting our daily routines and even our sleeps. Being a relatively new concept, phubbing refers to the act of overly engaging with one's phone while dismissing those around in the social settings. In this context, partner phubbing involves individuals exhibiting this neglect in the presence of their romantic partners. Evidence suggests that higher partner phubbing may lead to lower relationship satisfaction and higher perceived stress. The aim of the present cross-sectional study was to examine whether relationship satisfaction and perceived stress mediate the relationship between partner phubbing and sleep quality. Four hundred twenty-three individuals (females = 78.5%, M-age = 29.19, SD = 6.87) participated in the study and completed the measures of partner phubbing, relationship satisfaction, perceived stress, and sleep quality. The results of the serial mediation analyses showed that partner phubbing was not a direct predictor of sleep quality. However, the relationship between partner phubbing and sleep quality was mediated by the four indirect paths through relationship satisfaction (beta = 0.04, p < .05), perceived stress (beta = 0.09, p < .05), relationship satisfaction-perceived stress (beta = 0.02, p < .05), and perceived stress-relationship satisfaction (beta = 0.00, p < .05). The findings suggest that partner phubbing may diminish sleep quality by reducing relationship satisfaction and increasing perceived stress levels. Alternatively, perceived stress exacerbated by partner phubbing could reduce relationship satisfaction, which eventually worsens sleep quality. Digital detox programs, group interventions, emotion-focused couple interventions, and stress management training can help overcome the effects of partner phubbing on sleep quality.

    Flexural Strength Design Criteria for Concrete Beams Reinforced With High-Strength Steel Strands
    (Sage Publications inc, 2012) Baran, Eray; Arsava, Tugba
    This paper summarizes the result of a study investigating the flexural behavior of concrete beams reinforced with high-strength prestressing strands. Thirteen concrete beams reinforced with either conventional reinforcing bars or high-strength strands were fabricated and load tested in the experimental part of the study. No distinct difference was detected between the experimentally obtained cracking patterns of the two groups of beams. For the same reinforcement amount, beams reinforced with high-strength strands exhibited slightly smaller service stiffness than those reinforced with conventional reinforcing bars. A comparison of the measured and numerically predicted response of beam specimens indicated that the cracking load, peak load, and the deformation capacity of concrete beams can be accurately determined by a sectional analysis procedure for both types of reinforcement. The level of ductility present in concrete beams reinforced with high-strength strands is evaluated using the parameter called "displacement deformability ratio." Using the numerically determined maximum reinforcement limits for concrete beams reinforced with high-strength strands, an expression was proposed to be used at the design stage.

    Women's Professional Career and Culture: Software Organizations in India
    (Sage Publications inc, 2022) Mishra, Deepti; Mishra, Sushma; Ostrovska, Sofiya
    In this work, we conduct an investigation on perspectives and existing barriers for women trying to pursue a career in the Indian software industry. The study is focused on three dimensions: organizational policies and practices, workplace environment, and social-familial factors. Another goal is to compare the perception of male and female software professionals concerning the impact of these dimensions on the careers of female software professionals. The study reveals that formally organizations provide gender-neutral policies, and currently the emphasis needs to be placed on their implementation. It has been observed that, on the whole, there is a favorable work environment and unbiased attitude toward female software employees. At the same time, we conclude that, despite significant progress, hurdles - mainly coming from the society and family traditions-still exist restraining flourishing careers of women in the software sector.

    Physical Fitness and Maternal Psychosocial Status in Children With Autism Attending a Regular Physical Activity Program
    (Sage Publications inc, 2022) Sahan, Ayse Kubra; Ozturk, Nazan; Calik-Kutukcu, Ebru; Aksu, Hatice; Tunagur, Mustafa Tolga; Arikan, Hulya
    The aim of this study was to compare physical fitness-related parameters in children with mild to moderate autism and their typically developing (TD) peers to determine maternal anxiety level and quality of life. Children with autism had significantly worse scores for all Munich Fitness Test (MFT) parameters except step test heart rate and had lower physical activity levels compared to the TD children (p < .05). There was no difference between groups in terms of postural deviations or maternal anxiety scores (p > .05). The MFT total score was associated with higher maternal quality of life scores (r = .605, p = .006). This study showed that despite participating in a regular physical activity program, children with mild to moderate autism have lower physical fitness and activity levels compared to their TD peers, whereas better physical fitness in children with autism has a positive effect on their mothers' quality of life.
