The attitudes of one teacher and her students towards using Internet sources to develop students' reading skills
Ankara : The Department of Teaching English as a Foreign Language, Bilkent University, 2010.Thesis (Master's) -- Bilkent University, 2010.Includes bibliographical references leaves 114-116.This study investigated students’ and the teacher’s attitudes towards the benefits
and challenges of using Internet sources to develop students’ English reading skills. The
data was collected through questionnaires distributed to 42 students, interviews
conducted with a teacher and 12 students in the Preparatory School at Cumhuriyet
University and a journal kept by the teacher.
Student questionnaires and interviews investigated students’ and the teacher’s
general attitudes towards the benefits and challenges of using Internet sources to develop
reading skills and their opinions about three different Internet-based reading tasks:
teacher-centred, teacher-facilitated and learner-determined. The teacher journal aimed to
provide in-depth information about the teacher’s perceptions on each Internet based
reading task and her observations of the students. The data gathered from all instruments were analyzed qualitatively and
quantitatively. Findings revealed that both students and the teacher have positive
attitudes towards using Internet sources to improve reading skills. In addition, the
teacher and the students believe that reading skills can be developed by means of
Internet sources. The data gathered from both qualitative and quantitative analysis
showed that students have positive attitudes towards doing all types of Internet-based
reading tasks. With regard to the teacher’s attitudes, although she has positive attitudes
towards using teacher-determined and learner-determined tasks in her classes, she has
negative attitudes towards using teacher facilitated task. Both the teacher and the
students think that the most challenging task among all the Internet-based reading tasks
is the teacher-facilitated one. However, although both the teacher and students found it
challenging, they think that it is beneficial to developing students’ reading skills.Koçak, ArzuM.S
Prevalence of Turkish parent refusal and hesitance rate and its associated factors in childhood vaccination
The Rejection of childhood vaccination is still a major issue in many countries. The aim of the study was to assess prevalence of Turkish parent refusal and hesitance rate and its associated factors in Childhood vaccination. A crosssectional study was carried out at the General Pediatric Poly Clinic of Ankara Keçören Training and Research Hospital from January – to April 2020. Data was collected using a questionnaire via face to face interviews with parents. We included parents who have 6 months to 7 years old children, who visited the clinic during the study period and who accepted to join the study. A total of 809 mothers and 132 fathers participated in the survey. Among the parents, 1.2% of them refused the vaccination of their children and 4.8 % of them had incomplete vaccination of their children. More than half (67.4%) of the parents have a high level of knowledge about vaccines. knowledge level was statistically significantly different based on the participant’s occupation, income, education background and father’s age (P 0.05). Parents with one child had bad attitudes towards vaccines (35.4%)
TURKISH JOURNAL of ONCOLOGY A Study of Uro-oncology Patient Perceptions of Social Support and Hope Levels
OBJECTIVE The present study measured social support perceptions and hope levels of uro-oncology patients diagnosed with cancer and examined how they vary according to sociodemographic variables. METHODS Research was conducted on 143 uro-oncology patients in Konya, Turkey, using a sociodemographic information form, the Multidimensional Scale of Perceived Social Support (MSPSS) and the Hope Scale. RESULTS Patient mean multidimensional perceived social support score was quite high at 62.14±14.99, and mean hope level score was 20.62±4.50. Hope level score was significantly higher in male patients. It was also higher for patients with dependents and for patients who believed their cancer was treatable. Perceived social support levels of patients with dependents and patients who believed their cancer was treatable were also significantly higher. CONCLUSION Hope levels of uro-oncology patients are affected positively by high levels of perceived social support. Women, patients with dependents, and patients who develop a positive attitude toward their cancer treatment were more hopeful than others
MITF-MIR211 axis is a novel autophagy amplifier system during cellular stress
Macroautophagy (autophagy) is an evolutionarily conserved recycling and stress response mechanism. Active at basal levels in eukaryotes, autophagy is upregulated under stress providing cells with building blocks such as amino acids. A lysosome-integrated sensor system composed of RRAG GTPases and MTOR complex 1 (MTORC1) regulates lysosome biogenesis and autophagy in response to amino acid availability. Stress-mediated inhibition of MTORC1 results in the dephosphorylation and nuclear translocation of the TFE/MITF family of transcriptional factors, and triggers an autophagy- and lysosomal-related gene transcription program. The role of family members TFEB and TFE3 have been studied in detail, but the importance of MITF proteins in autophagy regulation is not clear so far. Here we introduce for the first time a specific role for MITF in autophagy control that involves upregulation of MIR211. We show that, under stress conditions including starvation and MTOR inhibition, a MITF-MIR211 axis constitutes a novel feed-forward loop that controls autophagic activity in cells. Direct targeting of the MTORC2 component RICTOR by MIR211 led to the inhibition of the MTORC1 pathway, further stimulating MITF translocation to the nucleus and completing an autophagy amplification loop. In line with a ubiquitous function, MITF and MIR211 were co-expressed in all tested cell lines and human tissues, and the effects on autophagy were observed in a cell-type independent manner. Thus, our study provides direct evidence that MITF has rate-limiting and specific functions in autophagy regulation. Collectively, the MITF-MIR211 axis constitutes a novel and universal autophagy amplification system that sustains autophagic activity under stress conditions.No sponso
The effect of salt (NaCl) concentrations on leaf and bulb development of hyacinth (Hyacinthus orientalis “Fondant”) growing in water-culture
In this study, the effects of salt concentrations applied to hyacinth (Hyacinthus orientalis “Fondant”) on leaves and bulbs were determined in water culture. In water culture, a solution of ½ percent diluted Hoagland nutrient solution was used. Four different concentrations (500 (S1), 1000 (S2), 2000 (S3) and 4000 ppm (S4)) salt (NaCl) were applied together with the control group (T0) which was not salted into the water culture. Hyacinth bulbs were planted in pots with peat:perlite mixture in 1:1 ratio. They were kept in the laboratory until leaves emerged. The hyacinths taken into the water culture were applied with salt in the flowering stage. At the end of the study, according to the applications the lowest and highest average values were in the number of leaf, leaf length, leaf width, bulb weight, bulb length and bulb width as 6.000-7.026 pieces (S4-S3), 107.401-254.343 mm (S4- S1), 20.723-29,769 mm (S3-S1), 20.35-24.900 g (S4-S3), 32.364-36.724 mm (S4-S3) and 35.215- 36.618 mm (S4-S3), respectively. The difference between the average values of the applications was statistically insignificant in bulb width; the difference between leaf number, leaf length and leaf width averages at p <0.001; bulb weight at p <0.05 and bulb length at p <0.01 level was found to be significant. At the end of the study, it was determined that 4000 ppm salt application (S4) had a negative effect on leaf and bulb growth
The Effects of Different Planting Times and Vermicompost Applications on The Some of Morphological Properties of The Hyacinth (Hyacinthus orientalis "Fondant") Growing in The Siirt Ecological Conditions
In this study, Hyacinthus orientalis “Fondant” hyacinth variety bulbs grown in Siirt ecological conditions were planted in 2016 at 15 days each between 14 November (1PT), 01 December (2PT) and 16 December (3PT). The study was carried out with 3 replications according to the “randomized block test design” in the experimental area of the Siirt University Faculty of Agriculture. Earthworm fertilizer (V) (vermicompost) were applied to the planting pits of the bulbs planted at different planting times with 100 g/bulb In addition, control plots (C) which are not fertilized were formed. In the course of morphological observations, as a result of interactions of planting time and fertilizer application,the lowest and the highest average values were obtained, respectively, 7.980-8.540 unit for leaf number (3PTxC-3PTxV), 154.633-191.873 mm for leaf length (1PTxV-3PTxC), 20.990-30.683 mm for leaf width (2PTxC-1PTxV), 215.106-232.376 mm for plant height (1PTxC-2PTxV) and 13.106-14.886 mm for stem thickness (3PTxC-2PTxC). Among these mean values, only the difference between mean stem thickness and planting times were taken into consideration, the difference between the average value of leaf length were was found to be statistically significant (p<0.01). At the end of the study, it was determined that vermicompost had a more favorable effect on the parameters than the control and the 2 and 3. planting times were more suitable for the cultivation of hyacinths
The effects of different planting times and vermicompost applications on the flowering of the hyacinth (hyacinthus orientalis "fondant") growing in the siirt ecological conditions
In this study, Hyacinthus orientalis “Fondant” bulbs grown in Siirt ecological conditions were planted in 2016 at 15 days each between 14 November (1PT), 01 December (2PT) and 16 December (3PT). The study was carried out with 3 replications according to the “randomized block test design” in the experimental area of the Siirt University Faculty of Agriculture. Earthworm fertilizer (V) (vermicompost) were applied to the planting pits of the bulbs planted at different planting times with 100 g/bulb In addition, control plots (C) which are not fertilized were formed. In the course of phenological and morphological observations, as a result of interactions of planting time and fertilizer application, the lowest and the highest average values were obtained, respectively, between 101.923- 134.213 days for first flowering time (3PTxC-1PTxV), 103.103-135.766 days for a full flowering time (3PTxC- 1PTxV), 104.843-137.670 days for harvest time (3PTxC-1PTxV), 99.613-106.223 mm for flower height (2PTxV-1PTxV), 50.433-58.970 mm for flower width (2PTxC-3PTxV), 17.366-185.10 mm for floret length (1PTxV-2PTxV), 22.393-27.546 mm for floret width (1PTxC-3PTxC). Among these mean values, only the difference between mean length of floret was found to be statistically significant (p<0.01); when the planting times were taken into consideration, the difference between the average width of the flower (p<0.05) with all the flowering durations and the floret width (p<0.01) were statistically significant. The difference between the parameters of the planting time and the parameters of control and vermicompost applications were not statistically significant. As a result, the planting time interval for hyacinth plants was not determinative for the parameters examined. Regardless of the date of planting, bulbs were bloomed at approximately the same time. It is obvious that late planting time will be advantageous for irrigation and other maintenance

Buna ek olarak, bu araştırma öğrenci podcastleri oluşturup kullanmanın öğrencilerin konuşma becerilerini geliştirmeye ne derecede olumlu katkı sağladığını sorgulamıştır. Çalışma için gerekli olan bilgi, Hacettepe Üniversitesi’ndeki 90 öğrenciye dağıtılan anketler, 33 öğrenciyle yapılan mülakatlar ve ön test ve eğitim sonrası konuşma testinin uygulanması ile toplanmıştır.
Toplanan veri nitel ve nicel yöntemlerle analiz edilmiştir. Bulgular, öğrencilerin konuşma becerilerini geliştirmede öğrenci podcastleri oluşturma ve kullanma konusunda olumlu bir bakış açısına sahip olduğunu göstermiştir. Öğrenciler, öğrenci podcastlerinin konuşma becerilerini geliştirmeye oldukça fayda sağladığına inanmaktadırlar. Ayrıca, öğrencilerin, öğrenci podcastleri oluşturma ile ilgili düşüncelerinin demografik özelliklere göre (cinsiyet ve İngilizce öğrenme süresi) istatiksel olarak önemli ölçüde değişiklik gösterdiği bulunmuştur. Bununla beraber, öğrenci podcastlerinin yardımcı eğitimsel bir araç olarak etkililiği konusunda, ön ve eğitim sonrası konuşma testleri, öğrenci podcastleri oluşturup kullanmanın öğrencilerin konuşma becerilerini geliştirmeye önemli bir katkı sağladığını göstermiştir
Seksüel iki tiplilik (Dimorphism)
There are some hypotheses to explain the cause and maintenance mechanisms of differences between the sexes with species. Among these mechanisms sexual selection, competition for food researches, female reproduction strategy and energy requirement for reproduction will be reviewed in the fi rst part of the study. Differences between the sexes provide a reproduction advantage to the individual. On the other hand, sexual dimorphism may cause some disadvantages directly to the ornamented individual or indirectly to its partner. The disadvantages of the sexual dimorphism will be discussed in the second part of the study. Types of the sexual dimorphism, which are ranging from size to behavior either common to most of the animal species or unique for some of the species, will be reviewed in the last part of the study
