    Developmental Patterns in Internal Modification of Requests a Quantitative Study on Turkish Learners of English
    (John Benjamins B V Publ, 2012) Goy, Elif; Zeyrek, Deniz; Otcu, Bahar
    The present cross-sectional study investigates the development of internal request modification of Turkish learners of English. The data were collected through role-play performances of participants from two different English proficiency levels in four situations and compared against native speakers of American English. The situations varied in terms of power, social distance and imposition. By statistical means, it was shown that beginner learners underused syntactic and lexical/phrasal downgraders (except please) and higher proficiency learners showed a slow development in their employment of both subtypes. No clear correspondence between social factors and the use of internal modifiers was found. The results suggested weak attentional control over pragmatic knowledge. It is concluded that the reason for slow pragmatic development must be multicausal.

    Comparison of Hematopoietic and Spermatogonial Stem Cell Niches From the Regenerative Medicine Aspect
    (Springer international Publishing Ag, 2018) Kose, Sevil; Yersal, Nilgun; Onen, Selin; Korkusuz, Petek
    Recent advances require a dual evaluation of germ and somatic stem cell niches with a regenerative medicine perspective. For a better point of view of the niche concept, it is needed to compare the microenvironments of those niches in respect to several components. The cellular environment of spermatogonial stem cells' niche consists of Sertoli cells, Leydig cells, vascular endothelial cells, epididymal fat cells, peritubular myoid cells while hematopoietic stem cells have mesenchymal stem cells, osteoblasts, osteoclasts, megacaryocytes, macrophages, vascular endothelial cells, pericytes and adipocytes in their microenvironment. Not only those cells', but also the effect of the other factors such as hormones, growth factors, chemokines, cytokines, extracellular matrix components, biomechanical forces (like shear stress, tension or compression) and physical environmental elements such as temperature, oxygen level and pH will be clarified during the chapter. Because it is known that the microenvironment has an important role in the stem cell homeostasis and disease conditions, it is crucial to understand the details of the microenvironment and to be able to compare the niche concepts of the different types of stem cells from each other, for the regenerative interventions. Indeed, the purpose of this chapter is to point out the usage of niche engineering within the further studies in the regenerative medicine field. Decellularized, synthetic or non-synthetic scaffolds may help to mimic the stem cell niche. However, the shared or different characteristics of germ and somatic stem cell microenvironments are necessary to constitute a proper niche model. When considered from this aspect, it is possible to produce some strategies on the personalized medicine by using those artificial models of stem cell microenvironment.

    E-mentoring in global software development teams: Success factors to develop a common culture
    (IGI Global, 2012) Colomo-Palacios,R.; Mishra,A.; Casado-Lumbreras,C.; Soto-Acosta,P.
    Global Software Development (GSD) teams face communication and coordination problems due to spatial, temporal, and cultural separation between team members. Cultural diversity and cross-cultural management are significant issues among GSD teams. In software development projects, mentoring dramatically reduces the learning curve for novice human resources. Due to the large amount of electronic communication instruments, a remarkable number of different e-Mentoring concepts have emerged, which provides opportunity for mentoring that would not otherwise be possible. This chapter presents key success factors to enable e-Mentoring as a tool to develop a common culture in GSD scenarios. These success factors enable the correct application of mentoring programmes and the use of this to build a common culture in organizations that perform GSD. © 2013, IGI Global.

    Magnetic-Based Cell Isolation Technique for the Selection of Stem Cells
    (Humana Press inc, 2019) Korkusuz, Petek; Kose, Sevil; Yersal, Nilgun; Onen, Selin
    Magnetic-activated cell sorting (MACS) is the technology that is recently used as a magnetic-based cell isolation/purification technique. This technique enables the isolation and selection of germ, hematopoietic, and somatic stem cells including skin stem cells (SkSCs). Here, we have tried to describe the isolation of stem cells by MACS using CD34 antigen for SkSCs, again CD34 for hematopoietic stem cells (HSCs) and Thy-1 for spermatogonial stem cells (SpSCs). MACS allowed the isolation of CD34+, CD34+, and Thy-1+ human SkSCs, HSCs, and SpSCs with minimum 98% purity.

    The Meaning of Innovation and Entrepreneurship in Developing Countries
    (Springer, 2009) Capoglu, Goekhan
    The meaning of innovation and entrepreneurship and policies to promote innovation differ across groups of developing countries. On the one hand, there is a small group of countries such as China, South Korea, Brazil, and Mexico which has achieved a certain stage of capitalistic development that provides an institutional environment for encouraging innovation and entrepreneurship. On the other hand, there is a large group of countries in Africa and Asia as well as in Latin America which lacks the critical level of capital accumulation even for sustainable development let alone for the growth of innovation and entrepreneurship. There is also a group of countries such as India with a world-class high-technology clusters developing in the midst of increasing poverty. That is, a generalization of policy proposals will fail to address the specific needs of country groups with different institutional characteristics. Appropriate government policies need to be designed to address specific needs of different country groups.
