Article Citation - WoS: 17Citation - Scopus: 16Child maltreatment in Turkey: Comparison of parent and child reports(Czech National Institute of Public Health Srobarova 48 Prague 10042 10, 2016-09-01) Zeynep Baskaya Sofuoǧlu; Gorkem Sariyer; M. Gökalp Ataman; Ataman, M. Gokalp; Sarıyer, Görkem; Sofuoğlu, Zeynep; Sanyer, Gorkem; Gökalp Ataman, M.Background and Aim: Child maltreatment i.e. abuse and neglect is a significant problem worldwide and can cause impaired physical and mental health throughout life. The true extent still remains unknown in all countries including Turkey. The aim of this study was to apply the two versions of the International Society for the Prevention of Child Abuse and Neglect (ISPCAN) Child Abuse Screening Tool of ICAST-C and ICAST-P which are used to assess child and parent feedback and to compare reports given by children and those given by parents. This is the first study of its kind conducted in Turkey. Methods: First ICAST was translated into Turkish by bilingual experts. Students and their parents were asked to complete ICAST-C and ICAST-P respectively with the help of trained researchers. In total data from 2 608 matched reports (2 608 children and 2 608 parents) was obtained. Descriptive statistics were used to evaluate demographical variables and chi-square tests were employed to investigate the statistical significance of comparisons. Results: The present study demonstrated that Turkish parents consider rebukes insults and corporal punishment effective ways of disciplining children. According to parents’ reports the use of psychological abuse was most prevalent against boys aged 16 while the use of physical abuse was most prevalent against boys aged 13. A statistically significant relationship was found between parents’ economic conditions and child abuse (p < 0.01). No significant relationship was detected between maternal educational levels and child abuse (p > 0.05). However the relationship between paternal educational background and psychological abuse was observed to be significant (p < 0.05). A comparison of children’s and parents’ reports shows that parents tended to under-report child maltreatment. Conclusions: The results show that there is a significant healthcare problem in Turkey since child maltreatment is prevalent but parents are not generally aware of its extent. Possible approaches to changing this situation include efforts to increase education levels promoting public awareness and strengthening political commitments. © 2016 Elsevier B.V.

Cognitions are seen as vulnerability factors in the development and maintenance of BPD. The present study aims to contribute to the cognitive literature on BPD by examining depressive and hypomanic attitudes and their contribution to the prediction of BPD diagnosis as well as by exploring the relationship between dysfunctional cognitions and clinical features (types of episodes experienced duration of illness and duration of remission). Methods: One hundred and eighteen remitted bipolar patients and 103 healthy controls completed the Mood Disorder Questionnaire (MDQ) Turkish Brief-Hypomanic Interpretations and Positive Predictions Inventory (HAPPI) and Dysfunctional Attitudes Scale. Results: The bipolar group had significantly higher depressive and hypomanic attitudes than the control group. No significant differences were found regarding the types of episodes experienced and duration of illness. However both types of attitudes decreased as the duration of remission increased. They were also found to contribute to the prediction of bipolar diagnosis together with the screening of the MDQ. Conclusion: The results pointed out that dysfunctional cognitions may be utilized as possible indicators for the risk of relapse in clinical groups and vulnerability for BPD among other populations. © 2015 Elsevier B.V.

Based on a simulated negotiation this study induced emotions by providing negative feedback on how negotiating partners perceived and evaluated each other's behavior. Then relationships were examined between negative emotions and emotional regulation strategies misrepresentation of information tolerance of ambiguity and negotiators' profit. A total of 228 undergraduate students enrolled in an economics course in the Faculty of Law and the Faculty of Management at a university in Ankara participated. There were 130 students in the experimental group and 98 students in the control group, 102 were men and 126 were women ages 17 to 35 years (M = 22.6 yr. SD = 2.3). A simulated negotiation process was used. Regression coefficients suggested positive relation between Emotional Reaction and the use of a Suppression strategy and Misrepresentation of Information. Negative coefficients were obtained from scores between Emotional Reaction and Cognitive Reappraisal and Tolerance of Ambiguity. The regression also suggested there were negative regression coefficients linking Misrepresentation of Information and Suppression strategies to Negotiators' Profit. Positive regression coefficients linked Tolerance of Ambiguity to Negotiators' Profit. Mediating variables explained 55% of variance in Negotiators' Profit, the majority (43%) was explained by Cognitive Reappraisal. © Perceptual and Motor Skills 2008. © 2008 Elsevier B.V.

The procedure is called post-retrieval extinction (PRE). However from the time it emerged it has suffered from inconsistencies in the ability of researchers to replicate the seemingly established effects. Extant literature implies that conditioned fear might be differentially sensitive to the nature of conditioned stimuli (CS) used. The aim of the present study therefore is threefold. First we aimed to replicate Schiller et al. (Nature 463 49–53. 2010) procedure in which the PRE had produced positive results with arbitrary CSs only. Also we examined the PRE as a function of CS type (ecological-fear-relevant (images of spider and snake) vs. arbitrary (images of yellow and blue circles)). Finally we aimed to investigate the long-term effects of the PRE (i.e. 24 h 15 d and 3 mo). The study consisted of acquisition re-activation and extinction and re-extinction phases. Dependent measure was the recovery of fear responses as indexed by the skin conductance responses (SCRs) and arousal ratings of the participants at the last trial of the extinction and the first trial of the re-extinction. All groups showed significant acquisition and extinction patterns compared to the other two groups (i.e. 6 h after the activating CS and without an activating stimulus) only the group that undertook extinction trials 10 min after the activating CS showed a sustained extinction. Thus our findings provided further evidence for the robustness of the PRE paradigm in preventing the recovery of extinguished fears behaviorally both with ecological and arbitrary stimuli. © 2023 Elsevier B.V.

This is due to the fact that the energy found in nature is generally consumed at an optimal level in order for it to endure. Biomimetic inspiration in many designs and applications is widely displayed including within the field of engineering. In this paper we were inspired by the double set of jaws found in the moray eel which gives this fish a huge advantage while hunting with a mobile pharyngeal jaw that works together with its oral jaw in order to overcome ineffective suction capabilities. A procedure that mimics the hunting motion of the moray eel was utilized by considering the overall movement as a single degree of freedom with multiple outputs on account of the repeating motion that is required during hunting. This procedure includes structural and dimensioning synthesis wherein the latter was utilized with analytic kinematic synthesis for each linkage transfer. The flexibilities in parameters were taken into account with a novel multiple iterative kinematic synthesis algorithm that resulted in various mechanisms with the same purpose. Among the excessive number of resultant mechanisms the optimization was carried out by considering the highest torque transmission ratio at critical timings that were specified as bio-constraints. In the end the kinematic movement validation was utilized.
