Nest survival and transplantation success of formica rufa (Hymenoptera: Formicidae) ants in Southern Turkey: A predictive approach

Research highlights: Formica rufa is used widely for biocontrol in Turkish forests. Although ecological characteristics of red wood ant habitats are well known, the statistical significance of these characteristics and their effects on nest transplantation success are largely unknown. Having such knowledge on a local scale, however, can help to predict the success of a scheduled transplantation effort, and can prevent loss of time and money. Background and objectives: In the present study, we used nest transplantation data from southern Turkey to determine habitat parameters that have a significant impact on nest survival, and to investigate possibility of predicting transplantation success from habitat parameter data. Materials and methods: Algorithms of data mining are widely used in agricultural and forestry applications for a wide range of tasks. In the present study, we used descriptive statistics to summarize the transplantation profile according to six habitat parameters (altitude, aspect, canopy closure, landform, nest substrate, and slope). We also used classification, a data mining approach, with two of its methods (decision tree and naive Bayes) to determine the most important habitat parameters for nest survival and predict nest transplantation success in southern Turkey. Results: We found that altitude, aspect, and canopy closure were the most important factors affecting transplantation success. We also show that classification methods can be used in not only classifying, but also predicting the success rate of future transplantations. Thus, we show that the possibility of success for a given area can be predicted when certain parameters are known. Conclusions: This method can assist biological control practitioners in planning biocontrol programs and selecting favorable spots for red wood ant nest transplantation. © 2020 by the authors

RELATIONSHIP BETWEEN PERFORMANCE MANAGEMENT APPLICATIONS AND ORGANIZATIONAL JUSTICE PERCEPTIONS OF TEACHERS IN PRIMARY SCHOOLS

Bir okuldaki öğretmenlerin performans hedefleri, geliştirilmesi gereken yönleri, hizmet içi eğitim ihtiyaçlarını belirleme gibi durumların belirlenmesinde performans yönetiminin önemli rolü vardır. Performans yönetiminin amacı iş görenlerin eksikliklerini bulmak değil, onlara performans değerlendirmenin sonucunu bildirmek, bu sonuç üzerine yapılması gerekenler konusunda onlara rehberlik etmek, örgütün ulaşması gereken hedeflere uygun bir şekilde çalışmalarına devam etmelerini sağlamaktır. Okul içi adaletin sağlanması, öğretmen performansını ve motivasyonunu etkiler. Adaletin sağlandığı örgütlerde örgütsel bağlılık ve güven de artacağından örgüt performansının da artması kaçınılmazdır. Bu çalışma ilkokullarda performans yönetimi uygulamalarının düzeyini, öğretmenlerin örgütsel adalet algı düzeylerini ve performans yönetimi uygulamaları ile öğretmenlerin örgütsel adalet algıları arasındaki ilişkiyi saptamayı amaçlamaktadır. Tarama modelindeki araştırmanın evrenini 2013 - 2014 öğretim yılında Uşak ilinde çalışan 3660 öğretmen oluşturmaktadır. Basit tesadüfi örnekleme yoluyla 48 ilkokuldan 500 öğretmen örneklem olarak alınmıştır. Dağıtılan 500 ölçekten 446 sı geri dönmüş, araştırmacı tarafından incelemeler sonucunda 372 anket kullanılabilir olarak belirlenmiştir ve araştırmaya dahil edilmiştir. Araştırmada kullanılan ölçme aracı "Öğretmen Performans Yönetimi Ölçeği" ve "Örgütsel Adalet Ölçeği" dir. Ölçek boyutlarının örnekleme uygunluğunu test etmek için doğrulayıcı faktör analizi kullanılmış ve elde edilen verilerle ölçekler doğrulanmıştır. Verilerin analizi sonucunda performans yönetim sistemi uygulamalarının öğretmenlerin örgütsel adalet algıları üzerinde pozitif doğrusal etkisi olduğu saptanmıştır. Demografik değişkenler açısından ise bazı demografik değişkenlerin öğretmenlerin performans yönetimi sistemi algılarını ve örgütsel adalet algılarını etkilediği görülmüştürThe social unit, which consists of coordinated relationships of the workers who has got together in order to perform the planned objectives, is called as organization (Başaran, 2008). The planned and coordinated strength and activity group also make an organisation. The more this coordination creative, the more effective and lively the organisation is. Organisation may be thought as a network (Bursalıoğlu, 2012). Schools are organisations that perform the education and teaching task. The performance management has an important role in determining needs of in service education, the aspects that must be improved, current situations, and performance objectives. Determining performance objective- criteria, performance monitoring, performance development, performance evaluation and use of performance outcomes are the dimensions of performance management. The lasting success of organization depends on the high performance of members and valuation of their performance. Being known the skills and deficiencies of workers by the manager and valuation of their effort are some aspects that effect performance (Bingöl, 2006). The performance management has an important role in determining situations such as needs of in service education, the aspects that must be improved and performance objectives in a school. The aim of the performance management is not finding the deficiencies of the workers, but to inform them the results of performance evaluation, to guide them on this result, and to ensure them working approprate to organisation’s aims. Setting the justice inside the school effects teachers’ performance and motivation. As the organizational commitment and reliance will increase in organisations where justice is set, it is ineviatable that the performance of the organisation will increase. This study aims at determining tle level of the performance management practises, the level of teachers’ organizational justice perceptions, the relation between the performance management practises and teachers’ organizational justice perceptions in primary schools

Management of a Neonate with a Rare Congenital Palatosubglossal Synechia in Pierre Robin Sequence

Development of the human face begins in the fourth week of gestation, as a series of several complicated and well-organized sequential intrauterine events, disruption of which causes some sort of facial dismorhogenesis. Oral synechiae is a rare congenital anomaly usually recognized at birth secondary to airway or nutritional compromise. They help to understand the intrauterine developmental steps of the facial region. In this particular case with congenital palatosubglossal synechia, anterior soft palate of the patient with Pierre Robin sequence was repaired with the oral mucosal flap elevated from the floor of the mouth by using the synechial band as the pedicle of the flap

Use of Three-Dimensional MRI-Angiography in Preoperative Evaluation and Postoperative Management of Hemangiomas of Head and Neck Region

WOS: 000295398700059PubMed: 21959441Hemangiomas (proliferating endothelial tumors) are the most common benign tumors of infancy. Most often hemangiomas are self-regressing lesions without any treatment. Approximately 10% of hemangiomas cause complications such as major ulceration/destruction, distortion of involved tissues, and obstruction of a vital structure. When the situation becomes complicated, there are different treatment alternatives, ranging from systemic or local corticosteroid use to surgery. Sclerotherapy using intralesional polidocanol (Aethoxysklerol) injection may be used before surgery to decrease blood loss or when a vital structure of the face is in danger because of sudden increase in size of a surrounding hemangioma. Before any kind of treatment for both hemangiomas and vascular malformations, pre-operative diagnosis and anatomic position of the lesion must be documented thoroughly. With the help of magnetic resonance imaging, tridimensional vascular pattern of such lesions can be shown successfully. We used three-dimensional contrast-enhanced time-resolved magnetic resonance angiography to detect the changes of lesions for 2 children who have large hemangiomas on their faces, before and after sclerotherapy with polidocanol injection. The findings of three-dimensional magnetic resonance imaging studies help to better assess the success rate of treatment not only for us as the physicians but also for the parents of these children who cannot understand anything with standard two-dimensional radiologic imaging

Metforminin melanom cilt kanseri hücreleri üzerindeki etkisinin araştırılması

Apoptotic pathways are important for resistance to chemotherapeutics drugs and cancer development. Metformin is a safe, inexpensive and effective drug used to treat type 2 diabetes. Furthermore, although there is evidence of anticancer effects, the mechanisms by which metformin exerts the effects are unclear. Therefore, it was aimed to investigate Bcl-2, kaspaz-3, bax, wee-1, AIF, grp78 and gadd153 levels in metformin treated skin cancer cells. Materials and Methods: The skin cancer cells (B16F10) were treated with metformin and kaspase-3, bcl-2, wee 1, gadd153, grp78 and AIF levels were analyzed by using ELISA. Result: Treatment of metformin increased of proapoptotic proteins (kaspase-3, bcl-2, wee 1, gadd153, grp78 and AIF) and decreased antiapoptotic protein (bcl2). Conclusion: In conclusion, this study showed that metformin has apoptotic effect on melanoma skin cancer.Kanserlerde kemoterapötiklere gösterilen dirençte ve kanser gelişiminde apoptozisin önemli rolü vardır. Metformin tip 2 diyabet tedavisinde kullanılan güvenli, ucuz ve etkili bir ilaçtır.
