A maturity based qualitative information systems effectiveness evaluation of a public organization in Turkey
Among the top issues of information systems (IS) management is measuring and improving IS effectiveness. In that, the concept of IS effectiveness is widely accepted throughout IS research as the principle criterion for evaluating information systems. IS effectiveness is defined as the extent to which a given information system actually contributes to achieving organizational goals.. As the society moves from the industrial era to the information age,,ıs role in any organization shifts from efficiency to effectiveness. This case study presents an IS effectiveness evaluation methodology applied on a public organization. The paper supports in general the claim that the use of a systematic IS effectiveness evaluation approach can improve organizational performance
Middle School Mathematics Teachers' Views on the Use of Interactive Whiteboards
DergiPark: 707029tredGünümüzde geleneksel sınıf ortamlarının daha etkin ve teknolojik olarak donatılmış geleceğin sınıfları olma yolunda ilerleyebilmesi için, Millî Eğitim Bakanlığı tarafından çoğu okullardaki dersliklere etkileşimli tahta kurulumu gerçekleştirilmiştir. Bu bağlamda araştırmada etkileşimli tahta kullanımında aktif olarak görev alan ortaokul matematik öğretmenlerinin etkileşimli tahtayı derslerinin işlenişinde kullanımlarına yönelik görüşleri alınarak incelenmiştir. Araştırmada nitel araştırma desenlerinden betimsel araştırma yaklaşımı kullanılmıştır. Orta Anadolu’da bir il merkezinde görev yapmakta olan altı matematik öğretmeni ile bireysel görüşmeler gerçekleştirilmiştir. Görüşmeler ile etkileşimli tahta kullanımının, matematik dersine uygunluğu, öğretmenlerin bu teknolojiyi kullanım gerekçeleri, bu teknolojiyi kullanırken karşılaştıkları zorluklar, aldıkları eğitim ve önerileri ile ilgili temalar elde edilmiştir. Verilerin analizi sonucunda, öğretmenler matematik derslerinde etkileşimli tahta kullanmayı uygun bulurken, daha çok geometri dersinde kullandıklarını ve özellikle görselleştirme, öğrencinin ilgisini ve dikkatini çekme amacıyla kullandıklarını ifade etmişlerdir. Bu sonuçlara ek olarak öğretmenlerin tahtanın kullanımıyla ilgili yaşadıkları donanım ve eğitimle ilgili bazı zorluklar ve önerilere de yer verilmiştir.The Ministry of National Education has installed interactive whiteboards in classrooms in most schools to enable traditional classroom environments to become more effective and technologically equipped classes of the future. In this context, the opinions of middle school mathematics teachers who are actively involved in the use of interactive whiteboards were examined by taking into consideration the usage of the interactive whiteboard in the teaching of the lessons. The framework of the qualitative research approach was used in the study. Individual interviews were conducted with six middle school mathematics teachers working in a city in Central Anatolia. Themes which were obtained through qualitative analysis of interviews, were the interactive whiteboard, mathematics course suitability, teachers' reasons for using this technology, and their difficulties while using this technology, their education, and suggestions. As a result of the analysis, the middle school mathematics teachers stated that they use interactive whiteboards in mathematics courses. Still, they mostly use them in the geometry courses, especially for visualization, attracting student interest and attention. In addition to this, teachers' difficulties and suggestions related to the hardware and instructional experiences about using the whiteboard were included in the research
Holocene activity of Kütahya fault zone
Batı Anadolu Açılma Bölgesi’nin kuzeydoğu sınırında bulunan Kütahya Havzası BKB-DGD doğrultusunda uzanan bir çöküntü alanıdır ve güney kenarı belirgin bir morfoloji ile Kütahya Fay Zonu tarafından sınırlanmaktadır. Kütahya Fay Zonu boyunca jeolojik, jeomorfolojik ve jeofizik verilerden yararlanılarak yapılan çalışmalar sonucunda bu zonun, kuzey bloğun düştüğü normal fay geometrisine sahip 5 ayrı uzanımdan oluştuğu ve K50-70B doğrultusunda yaklaşık 22 km uzunluğa sahip olduğu ortaya konulmuştur. Paleosismolojik ve arkeosismolojik çalışmalar ise bu uzanım boyunca son 8000 yıl içinde yüzey kırığı oluşturan en az iki depremin meydana geldiğini ortaya koymaktadır. Bu depremlerden ilki M.Ö. 6000’li yıllarda, sonuncusu ise M.Ö. 1800’lü yıllarda Seyitömer Höyüğü’nde hasar oluşturan ve höyüğün terk edilmesine neden olan depremdir. Dolayısıyla, bu çalışmalar Kütahya Havzası’nın güneyini sınırlayan Kütahya Fay Zonu’nun Holosen’de tekrarlanan yıkıcı depremler ürettiğini ve geometrisi gözönünde bulundurulduğunda gelecekte de en az 6.5 büyüklüğünde deprem üretme potansiyeli bulunduğunu ortaya koymaktadır.Kütahya Basin which is located near the northeast boundary of the Western Anatolia Extension Region is a depression area that extends in WNW-ESE direction. Southern margin of the basin is bounded by a distinct fault morphology called Kütahya Fault Zone. Geological, geomorphological and geophysical studies on the Kütahya Fault Zone show that this zone consists of 5 different fault branches. Total length of the mapped fault zone is about 22 km in N50-70W direction. Paleoseismological and archeoseismological studies show that there are at least two surface rupturing earthquakes during the last 8000 years. First earthquake was occurred around 6000 BC and the last one was around 1800 B.C. after which the Seyitömer Tell was abandoned. Thus, this study indicates that the Kütahya Fault Zone has produced destructive earthquakes during Holocene and considering the length of the fault zone, it is possible to suggest that the fault zone has earthquake potential at least 6.5 magnitude.Publisher's Versio

Process based information systems evaluation: towards the attributes of "PRISE"
Purpose – The purpose of this paper is to demonstrate the importance of undertaking a systemic view of information systems evaluation that augments the frequently reported prescriptive (cost/benefit) analysis approaches.
Design/methodology/approach – The paper adopts a qualitative case perspective and derives a framework for substantive information systems evaluation factors (PRISE). Three empirical formulations are considered and a comparison made to determine the content and context of the findings.
Findings – The findings support the flexibility and relevance of PRISE as a framework for information systems evaluation. It notes the objectives, relations and components for explicitly identifying the outputs required to make a valid assessment of the systems.
Research limitations/implications – The study is limited contextually where attention should be made not to generalise the findings beyond the empirical findings within the case analysis. Further studies may usefully include the main features of PRISE but taking into account their unique research environment.
Practical implications – The study supports a practitioner perspective through a consideration of a holistic approach to information systems evaluation. Managers may implement the notion of including people, resources and benefits in their attempts to determine the added value of these systems to the organisation that extends beyond a simple financial calculation.
Originality/value – The paper is highly original as the framework has been derived through both theoretical constructs and empirical analysis. It provides an innovative approach to information system evaluation that is intellectually sound and practically orientated
A rare location and unusual development: Antecubital leiomyoma
Leiomyomas are benign soft tissue neoplasms which are originated from smooth muscle cells. Leiomyomas rarely occur in the upper extremity. To our knowledge, there have been no reports of a leiomyoma of the forearm which occured after intravenous catheterisation in Turkish literature. Herein, we report such a case of antecubital leiomyoma in a 52-year-old man. The case is presented due to its rarity and the risk of tumor misdiagnosis. Leiomyomas should be considered in the differential diagnosis of solitary masses of the extremities
Simple method for determining the size of the ProSeal laryngeal mask airway in children: a prospective observational study
Abstract Background and objectives: The size of the ProSeal laryngeal mask airway in children is determined by the patient's weight. However, in some instances, an alternative method may be required. This study aimed to compare sizing by the auricle with conventional ProSeal laryngeal mask airway sizing by weight in children. Methods: After approval by the institutional ethics board and written informed consent from parents, 197 children with American Society of Anesthesiologists physical status I-II who were scheduled for a routine genitourinary operation were included in the study. The correct ProSeal laryngeal mask airway size was determined according to the size of the auricle in children. The results were compared with the standard weight-based method recommended by the manufacturer's guidelines. The patients were classified into different groups depending on the ProSeal laryngeal mask airway sizes as determined by both methods. Agreement between both techniques was evaluated with κ coefficient statistics. Results: Insertion and adequate ventilation were achieved in 185 patients at the first attempt, and 12 patients required a second attempt. Three patients had to be intubated. Agreement between the two methods of size selection of the ProSeal laryngeal mask airway was moderate using κ statistics. Conclusions: Choosing the size of the ProSeal laryngeal mask airway in children according to the auricle of the child is valid and practical. In particular, this is an alternative method in situations where the patient's weight is unknown, such as in emergency situations
