An architectural assessment method for new exterior additions to historic buildings

The design approaches of new exterior additions to historic buildings have been among the ongoing debates in the field of architectural conservation. The aim of this study is to develop an assessment method, which can be used to determine the compatibility in architectural expression of the new addition in relation to the characteristics of a historic building. This method is based on the architectural analysis, which includes environmental relations, building-lot relations, mass relations and the facade composition of the historic building both before and after the new addition in relation to the value of a historical building. In this study, a selected group of historic buildings in ?zmir, Turkey with new exterior additions was analysed with regard to their exterior architectural characteristics in order to evaluate the compatibility of the new addition, by employing the use of contemporary conservation principles. The importance of this study is to guide architects to form the basis of a decision for developing an integrated approach in designing new additions in the course of the actual design process. On the other hand, the proposed method can be evaluated as a contribution to the emerging field of heritage impact assessments as well as scientific assistance to local governments to criticize specific projects of cultural heritage assets submitted for appraisal. Analysis results showed that the value of the historic building should first clearly be identified and a new addition should bear the identity of its own period. However, instead of altering the scale or form of the historic building, a new addition should complement and contribute to the sense of proportion, disposition and historical pattern.     

The effects of different syringe volume, needle size and sample volume on blood gas analysis in syringes washed with heparin

Introductıon:

We evaluated the effect of different syringe volume, needle size and sample volume on blood gas analysis in syringes washed with heparin.

Materials and methods:

In this multi-step experimental study, percent dilution ratios (PDRs) and final heparin concentrations (FHCs) were calculated by gravimetric method for determining the effect of syringe volume (1, 2, 5 and 10 mL), needle size (20, 21, 22, 25 and 26 G) and sample volume (0.5, 1, 2, 5 and 10 mL). The effect of different PDRs and FHCs on blood gas and electrolyte parameters were determined. The erroneous results from nonstandardized sampling were evaluated according to RiliBAK’s TEa.

Results:

The increase of PDRs and FHCs was associated with the decrease of syringe volume, the increase of needle size and the decrease of sample volume: from 2.0% and 100 IU/mL in 10 mL-syringe to 7.0% and 351 IU/mL in 1 mL-syringe; from 4.9% and 245 IU/mL in 26G to 7.6% and 380 IU/mL in 20 G with combined 1 mL syringe; from 2.0% and 100 IU/mL in full-filled sample to 34% and 1675 IU/mL in 0.5 mL suctioned sample into 10 mL-syringe. There was no statistical difference in pH; but the percent decreasing in pCO₂, K⁺, iCa²⁺, iMg²⁺; the percent increasing in pO₂ and Na⁺ were statistical significance compared to samples full-filled in syringes. The all changes in pH and pO₂ were acceptable; but the changes in pCO₂, Na⁺, K⁺ and iCa²⁺ were unacceptable according to TEa limits except fullfilled-syringes.

Conclusions:

The changes in PDRs and FHCs due nonstandardized sampling in syringe washed with liquid heparin give rise to erroneous test results for pCO₂ and electrolytes.     

Democratic environments offered to children at school,in the family,and in society: the case of Turkey

This research aims to investigate democratic environments offered to children in Turkey at school, in the home, and in society. A mixed method is a general type of research where qualitative and quantitative methods are used together. The researcher first collects quantitative and then the qualitative data. The study group in the research consisted of children in Kirsehir, a small city near the capital Ankara, in central Turkey. Democratic Environments scale and interview forms were used in the research. To analyze the obtained data, arithmetic averages, standard deviations, and percentages were calculated and multivariate analyses of variance conducted. The data obtained during interviews were analyzed through content analysis. Results show that even though Turkey accepts the Convention on the Rights of the Child, some problems remain associated with the democratic environment offered to children at school, at home, and in society.     

Academic Mobbing in Relation to Leadership Practices: A New Perspective on an Old Issue

Abstract

Constant pressures emanating from internal and external environments of the academy have resulted in many changes, one of which is the workplace mobbing, an old issue for the broader field of organization science but a relatively new phenomenon in the academic context. This study investigated the relationship between workplace mobbing and academic leadership and the results indicated that the more positive leadership there is in an institution, the less mobbing behaviors are observed.     

Teachers’ beliefs systems about improving transfer of algebraic skills from mathematics into physics in senior pre-university education

Senior pre-university education (SPE) students experience difficulties applying mathematics to physics. This paper reports the outcome of an online explorative quantitative study of teachers' belief systems about improving transfer of algebraic skills from mathematics into physics, conducted among 503 mathematics and physics teachers working in SPE. We used a questionnaire with 16 beliefs about improving transfer, and asked teachers to select a top 5 and distribute 50 points among them. We used agglomerative hierarchical clustering to cluster qualified SPE teachers with more than 10 years of teaching experience. We found 3 large clusters, each containing naïve and desirable beliefs about transfer. These clusters turned out to be rather coherent sets of beliefs. Hence, these clusters can be interpreted as belief systems, to a certain extent justifying Ernest's [(1991). The philosophy of mathematics education. London: Falmer.] idea to cluster teachers based on their belief systems. We found relations between our groups and those of Ernest. Since naïve beliefs turn out to be weak in each cluster, science teacher educators can help science teachers to change their harmful naïve beliefs, into desirable transfer enhancing beliefs. Furthermore, we discuss some implications of our results for science teacher educators, curricula, teachers and textbooks.     

Learning with the Natural Environment: How Walking with Nature Can Actively Shape Creativity and Contribute to Holistic Learning

Learning takes place in various spaces through human and nonhuman interactions. Considering the urgent need for rethinking how humans relate to nature, in this article we present a MA level course in the context of art, craft and design to discuss how learning with the natural environment approach can impact learning experiences. We introduce walking with nature as a creative method that fosters students’ ability to let the environment actively shape their creative events. The encounter with nature-based materials in their different forms and following the material's flow provides students with a foundation for their creative processes. This study proposes that walking can facilitate the entanglement between the student's knowledge and encountered materials, generating an emotional and dialogical relationship with the natural environment that contributes to a holistic learning experience. We propose that such an experience can help in comprehending the importance of the caring actions we need to take and maintain towards the nonhuman world.     

New School of Mustafa Satı Bey in Istanbul (1915)

This study has two purposes: the first is to present the general condition of public education in the late nineteenth and early twentieth centuries by showing the reformation process in educational institutes and teacher training, and the relationship between this process and the New Education movement in the Ottoman Empire; the second is to determine to what extent Mustafa Sat? Bey, often referred to as the Pestalozzi of the Ottoman Empire, contributed to the New Education movement through the analysis of his opinions on education, and his attempts to open a New School. As a result of Mustafa Sat? Bey’s analysis, New Education practices in the Ottoman Empire were stated to be practising a unilateral receiving-and-adapting procedure and the Ottoman Empire was positioned at the periphery in terms of the circulation of the movement. In his New School and in the Teacher Training School, Sat? Bey was concerned with the New Education movement both on an administrative and operative level. However, his practices were not sufficient to create his own theory and examine any other theory. Thus, when evaluated in terms of his contributions to the New Education movement, Sat? Bey is positioned somewhere between practical reformer and practitioner.     

Promoting field trip confidence: teachers providing insights for pre-service education

Pre-service teachers need experiences in practical matters as a part of field trip preparations programmes. For 14 years, a private, non-profit university in Turkey has involved pre-service teachers in field trip planning, implementation and evaluation. A programme assessment was conducted through a case study to examine the long-term effects of pre-service field trip preparation. Through a survey created for the study, teachers shared their field trip activities and reported confidence levels. The survey was administered to 44 alumni of the biology education department with a response rate of 72.7% (N = 32). This study will help researchers learn which programme areas need to be improved and can serve as a model for other institutions interested in evaluating field trip preparation programmes.     

Student Participation in Higher Education Institutions in Turkey

After the 2001 meeting of the European Ministers of Education held in Prague, higher education institutions in Turkey took serious actions in order to implement the goals of the Bologna Declaration (1999). Arrangements made for the democratization of universities and student participation in the decision‐making process formed one of the predominant actions. The formal point of these arrangements – aimed at student involvement in the university governance process via Student Councils and their representatives, was prescribed by law and forced universities to comply with the process. The present research provides information about the legal arrangements in higher education institutions concerning student involvement in the university decision‐making process and the obstacles met within the course of application. In addition, it presents the findings of an empirical study related to student representation and involvement in governance through the agency of the Student Councils.
