Hemodynamically significant ductus arteriosus (hsPDA) may alter organ perfusion by interfering blood flow to the tissues. Therefore, in infants with hsPDA, hypoxia occurs in many tissues. In this study, we aimed to investigate the diagnostic significance of serum (ischemia-modified albumin) IMA levels as a screening tool for hsPDA, and its relation to the severity of the disease in the preterm neonates. For this purpose, seventy-two premature infants with gestation age <34 weeks were included in the study. Thirty premature infants with hsPDA were assigned as the study group and 42 premature infants without PDA were determined as the control group. Blood samples were collected before the treatment and 24 h after the treatment, and analyzed for IMA levels. IMA levels in the study group (1.26 ± 0.36 ABSU) were found to be significantly higher than control group (0.65 ± 0.12 ABSU) (p < 0.05). In infants with hsPDA, a positive correlation was found between IMA and PDA diameter (ρ = 0.876, p = 0.022), and LA/Ao ratio (ρ = 0.863, p = 0.014). The cut-off value of IMA for hsPDA was measured as 0.78 ABSU with 88.89 % sensitivity, and 90.24 % specificity, 85.71 % positive predictive, 92.5 % negative predictive value [area under the curve (AUC) = 0.96; p < 0.001]. The mean IMA value of the infants with hsPDA before treatment was 1.26 ± 0.36 ABSU, and the mean IMA value of infants after medical treatment was 0.67 ± 0.27 ABSU (p = 0.03). We concluded that IMA can be used as a marker for the diagnosis and monitoring of a successful treatment of hsPDA.  相似文献   

Brand communication through digital influencers: Leveraging blogger engagement     

Ebru Uzunoğlu  Sema Misci Kip 《International Journal of Information Management》2014

The growing power of bloggers to influence their connected network has emerged as a new communication venue for brands. This study elaborates upon the role of bloggers in brand communication, and reveals how brands can engage with bloggers, currently considered as online opinion leaders, from the perspective of the two-step flow theory. Following clarification of the aims of the study, we report on in-depth interviews with 17 brand and digital agency representatives, selected because they regard communication with bloggers as an important strategy in increasing the influence of their brands among online communities. This exploratory study reflects current blogger communication implementations, and concludes with a discussion of seven major issues arising from the literature review and interviews (definition of bloggers, blogger selection criteria, digital integration, power of bloggers, long-term relationship building with bloggers, measurement, and budgetary issues in blogger communication). These areas represent relatively unexplored areas of blogger engagement from both an academic and managerial perspective. Based on the findings of the interviews, we propose a model which traces the influencer role of bloggers from the two-step flow theory perspective. This model is named as the brand communication through digital influencers model.  相似文献   

Exploring the Role of Trust in Scientists to Explain Health-Related Behaviors in Response to the COVID-19 Pandemic     

Muğaloğlu  Ebru Zeynep  Kaymaz  Zeynep  Mısır  Muhammet Emin  Laçin-Şimşek  Canan 《Science & Education》2022,31(5):1281-1309

The devastating COVID-19 pandemic has cast a light on the question of why trust in scientists is important. This mixed-method study aimed to explore the study participants’ trust in scientists about getting the COVID-19 vaccine. It also aimed to reveal which key sources of information participants followed about the pandemic. Participants’ health-related behaviors and justifications for their behaviors as a response to the pandemic were also explored to understand how trust in scientists and sources of information played a role in the fight against COVID-19. The responses of 1233 participants across Turkey were analyzed. The findings indicated that trust in scientists and compliance with the scientists’ suggested behaviors among the participants were quite high. It was also revealed that, for both trust and non-trust groups, participants questioned the reliability of information and the sources. Participants justified their behaviors mainly by referring to policies, e.g., masks, distance, and hygiene, developed and implemented with the collaboration of government, scientists, and the World Health Organization. Moreover, trust issues regarding scientists, government authorities, or other citizens were mentioned in participants’ justifications. The current study also shed light on the importance of building trust through an open and healthy dialogue among scientists, government authorities, and the public to overcome the COVID-19 pandemic. The study highlighted the need for scientifically informed citizens to deal with the problems, i.e., misinformation and disinformation, in the post-truth era such as not jeopardizing effective solutions to eliminate the pandemic, e.g., taking the vaccine.

Emotional labor and burnout among Turkish primary school teachers     

Uğur Akın  İnayet Aydın  Çetin Erdoğan  Nihan Demirkasımoğlu 《The Australian Educational Researcher》2014,41(2):155-169

Emotions play a critical role in teaching, especially in primary schools. Teachers have to manage their feelings in order to sustain a positive classroom climate. Managing feelings as a requirement of work is called emotional labor, which is a relatively new area of research in teaching. The main aim of this research was to investigate the type of emotional labor strategies Turkish primary school teachers often use and whether emotional labor is a predictor of burnout for primary teachers in a Turkish context. Also, the authors explore if there is a significant variation in emotional labor in terms of gender and school type (public/private). A survey was conducted with the participation of 370 primary school teachers from Ankara, Turkey. Results indicated that Turkish primary school teachers mostly engage in genuine emotions in their relationships with students. Female teachers use deep and surface acting strategies more often than males. Also, private school teachers were found to use deep acting strategies and display genuine emotions more often than public school teachers. Finally, it was found that emotional labor is a significant predictor of burnout among Turkish primary school teachers.  相似文献

Validation of the Career Adapt-Abilities Scale–Short Form across different age groups in the Turkish context     

Erkan Işık  Firuzan Yeğin  Sıddıka Koyuncu  Ayşe Eser  Fatma Çömlekciler  Kübra Yıldırım 《International Journal for Educational and Vocational Guidance》2018,18(3):297-314

A short 12-item version of the Career Adapt-Abilities Scale–Short Form (CAAS-SF) was validated across three different age groups in the Turkish context. Scale scores demonstrated adequate to high internal consistency and 4-week test–retest reliability, good fit with the original four-factor model, factorial invariance across gender and age groups, strong convergence with the 24-item version, negative associations with trait anxiety and work stress, and positive associations with career decision self-efficacy. It was concluded that the Turkish version of the CAAS-SF appears to be a valid and reliable measure for assessing career adaptability and using it in career education and counseling process.  相似文献   

Of Course Scientists Haven’t Seen Dinosaurs on the Beach: Turkish Kindergartners’ Developing Understanding of the Nature of Science Through Explicit–Reflective Instruction     

Ümran Alan  Serap Erdoğan 《Early Childhood Education Journal》2018,46(6):695-706

Although the importance of nature of science (NOS) instruction for learners as young as kindergartners is emphasised in a great number of documents and studies, very little research has been conducted in early childhood contexts. Thus, researchers are still not able to see a comprehensive picture of young children’s understandings of NOS. The purpose of this qualitative study is to investigate kindergartners’ developmental ability to comprehend tenets of NOS. Using an explicit–reflective approach and activities designed to develop their understandings of NOS, we instructed eight kindergartners for 10 days over the course of a month to document changes in their thinking. To this end, they were interviewed individually using Young Children’s Views of Science before and after instruction. The results indicate that generally, the kindergartners had an inadequate understanding of NOS before instruction but had developed it by the end of instruction. Each child’s understanding of the individual aspects of NOS developed to different degrees, creative NOS improving most substantially. This study corroborates that kindergartners are not developmentally constrained to develop informed NOS understandings. On the contrary, they are able to develop an informed understanding of NOS that can be improved by the implementation of explicit–reflective instruction.  相似文献   

Information retention’s relationships with flow,presence and engagement in guided 3D virtual environments     

Fatma Burcu Topu  İlknur Reisoğlu  Turkan Karakus Yılmaz  Yuksel Göktaş 《Education and Information Technologies》2018,23(4):1621-1637

The purpose of this study was to examine the correlation of different variables with information retention in guided 3D virtual learning environments by employing three experimental designs. In each experiments, different participants were included in the same population and different variables were considered. Information retention test, flow, presence, engagement scales were used as data collection tools. Namely measures of flow, presence and engagement were examined to see their correlation with retention in experiment 1, 2 and 3. As a result, not the total score of flow but focused attention, enjoyment and skill dimensions has a weak but significant correlation with information retention, while the challenge has a moderate and significant negative correlation. In the second experiment, retention had a significant, low-level relationship with teaching presence and cognitive presence, but it did not have a similar relationship with social presence. In the third experiment, information retention significantly correlated with affective and cognitive engagement, but not with behavioral engagement. Although the three studies’ participants were from the same population, It was seen that the differences in the level of relationship between information retention and the variables studied in each study. Nevertheless, it was found that the levels of flow, presence and engagement of students are important for information retention in a guided 3D virtual learning environment. The study is thought to guide researchers to design 3D virtual learning environments for different purposes, considering these variables.  相似文献
