A Sociological Standpoint to Authentic Scientific Practices and its Role in School Science Teaching
Mehmet C. AYAR,Bugrahan YALVAC
Journal of Kirsehir Education Faculty , 2010,
Abstract: In this paper we place an emphasis on authentic science practices grounded by anthropological and sociological lenses of science and discuss their implications for science teaching. We highlight the problem of typical science teaching as teaching merely about the “normal science” and ignoring the sociological characteristics of scientific practice. After briefly reviewing the sociological and anthropological perspectives of science, we propose including the social characteristics of science and the notion of communities of practice in designing science learning environments and considering them as essential components of the nature of science teaching practices. Next, we discuss the characteristics of authentic scientific practices as reported in recent studies and examine how researchers operationalized authentic science practices in their educational studies. Finally we suggest some implications for practice in augmenting students and teachers awareness about authentic science practices using the anthropological and sociological lenses.

Abstract: At the beginning of the 20th century plague had almost become a local, demographically ineffective and even an ordinary disease. However, even at such a late period, in the epidemics occured in any part of the ottoman territories, plague continued to cause economy based troubles similar to the ones in the previous centuries, due to the quarantines.
K rklareli (K rkkilise) Mekteb-i dadisi/// K rkkilise High School (In The Last Half Century Of The Ottoman Empire)
Mesut AYAR
History Studies : International Journal of History , 2010,
Abstract: K rkkilise High School which was opened in 1892 was fateful for the recent history of the region because in this region, it was the most important education intuitions in the last half century of the Ottoman Empire. Actually, the history of the school was begun with the opening as a middle school hence 1869-70’s because K rkkilise Middle School was converted into the high school by means of changing the length of the time of the education and the syllabus although a big majority of the students and the teachers and even the building stayed the same.The aim of the K rkkilise High School was growing up the persons who had sense of leadership. Therefore, a lot of people who was important for the recent history of the K rkkilise had received education from this school which was the only Muslim High School in town in that time. The school’s education was interrupted due to the invasions of Russians, Bulgarians and Greeks in 1877-78, 1912-13 and 1920-22, respectively. Apart from this, it had survived till the end of the administration of the Ottoman Empire

Dicle Medical Journal , 2010,
Abstract: Objectives: Hepatitis C and interferon may trigger autoimmunity. We aimed to investigate the effects of combination treatment of peginterferon alpha (peg-IFN) + ribavirin in patients with chronic hepatitis C (CHC) on thyroid function tests and thyroid auto antibodies.Materials and Methods: The study included 45 outpatients with proven CHC having normal thyroid functions and previously not treated. The patients received combination of Peg-IFN+ribavirin. Values of fT3, fT4, TSH, antitiroglobu-lin (Anti-Tg) and thyroid peroxidase antibody (Anti-TPO) were measured at initial, first, third and sixth months of treatment. Frequency of thyroid dysfunction was evaluated according to age and gender of patients.Results: Thyroid dysfunction emerged in 15 (%33.3) of 45 patients at the end of the six month of antiviral treatment. Symptomatic thyroid disease was confirmed in 2 patients. Subclinical hyperthyroidism was determined in four pa-tients (%8.9), and subclinical hypothyroidism in 3 patients (%6.7) at the end of third month.At the end of sixth month; symptomatic hyperthyroidism was observed in one patient (%2.2), subclinical hyperthyroid-ism in six (%13.3) and subclinical hypothyroidism in 7 patients (%15.6), and symptomatic hypothyroidism was deter-mined in one patient (%2.2).At the end of the sixth month of antiviral treatment; Anti-Tg antibodies were positive in 12 patients (%26.7) and anti-TPO in 11 patients (4 male and 7 female) (%24.5). No significant relationship was found between thyroid dysfunction and age, gender and ALT levels of patients (p>0.05).Conclusion: Periodic follow-up examinations should be done for thyroid autoimmunity and thyroid functions in CHC patients receiving combination treatment of Peg-INF+ribavirin.

Broadbent’s Cognitive Approach and Its Effect on Motor Performance in Sports  [PDF]
Mehmet Koyuncu
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.25073
Abstract: This study aimed to test Broadbent’s attentional filtering theory in the perceptual motor task of dart throwing. Dart board size was manipulated in order to reduce the amount of information to be filtered in the participants’ field of view. Sample consisted of 122 college students (63 males and 59 females) ranging in age from 17 to 36. Participants’ task was to throw 18 darts at the center of targets 45 cm, 30 cm and 15 cm in diameter. Performance was measured as radial distance from the bulls-eye of each dart. One way ANOVA, Repeated Measure of ANOVA was used in the analysis of the obtained data. The results of our study showed that dart throwing performance gave better results in cases where target’s field of view was reduced, compared to the ones in which target’s field of view was increased. Consistent with Broadbent’s central claim, results showed that fewer stimuli in the field of view required less processing, thus, better performance. Also, those subjects that were exercising regularly did better than the ones that were not exercising. This study provides evidence that reducing target’s field of view in dart throwing increases the chances to obtain better results.
A Survey on Geometric Dynamics of 4-Walker Manifold  [PDF]
Mehmet Tekkoyun
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.211163
Abstract: A Walker n-manifold is a semi-Riemannian n-manifold, which admits a field of parallel null r-planes, with r ≤ 2/n . It is well-known that semi-Riemannian geometry has an important tool to describe spacetime events. Therefore, solutions of some structures about 4-Walker manifold can be used to explain spacetime singularities. Then, here we present complex and paracomplex analogues of Lagrangian and Hamiltonian mechanical systems on 4-Walker manifold. Finally, the geometrical-physical results related to complex (paracomplex) mechanical systems are also discussed.
Embryo and Protoplast Isolation from Barlia robertiana Seeds (Orchidaceae)  [PDF]

American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.46A001

In the present study, it is aimed to investigate embryo and protoplast isolation from orchid seeds, because of know-how deficiency. As material Barlia robertiana seeds were subjected enzymatic process. Globular embryos with suspensor were fully removed by enzymatic maceration for between 100-180 min of incubation. The highest obtained embryo yields were found in Rapidase EX Color and Rapidase Vino Super, with degree of 89.2-90.3 × 103·g-1 MF and 86.4-91.3 × 103·g-1 MF, respec
