    The importance of entrepreneurship in a social structure results from the characteristics of entrepreneurs in determining the needs of a society and making investments in that area. Therefore, entrepreneurship is one of the most important factors of the progress for any social structure. On the entrepreneurship, the economics gives increasing importance to the characteristics of social structure. This situation has similar importance on the requirements of entrepreneurship. Two points should be considered in this context while analyzing entrepreneur behaviors. The first one is that entrepreneurship and entrepreneurs works with which social perception. The second one is that whether entrepreneurship and entrepreneurs use social environment they are in with different social groups. Beginning the transitional period from the industrial society to knowledge society in the world, the view of small enterprises can ensure competition efficiency and harmonization in especially social production area has become common. Therefore, ?small and medium enterprises' (SME) are started to be seen as enterprises that can accommodate changing conditions and fill demand gaps in the society quickly because of their dynamic structures. The importance of SMEs that involve great flexibility and productivity together at the international scale increases gradually. Thus, every country creates its own SME. Accordingly, this subject should be considered in terms of social culture since the SME-society relation involves originality for every society. Existing SME literature deals with SMEs independently from cultural structures of societies and considers them under the dominant economic theory. Thus, a standard SME and entrepreneur model approaching to all SMEs in all societies of the world with the same point of view occurs. Within the scope of the study, Turkey's process of social change was separated into mainly three terms starting from 1960 when the industrialization and urbanization rate increased. The effects of social structure characteristics of the terms on entrepreneurship are discussed. The discussion analyzes the policies of 9 different national development plans prepared by the governments and tried to be implemented in the terms between the years of 1963-2013 called as planned period and started at the same years in Turkey. This presentation is aimed at described the reflection of these policies, which are tried to be evaluated with social, economic, and spatial dimensions, on the local entrepreneur and local production spaces

    Journal of Childhood, Education & Society (JCES) was founded as a product of collective thought under the leadership of Dr. Mehmet Toran in July 2019 by a group of early childhood researchers who conduct both collaborative and independent academic research. Under the light of scientific research, current publishing policies cannot eliminate inequalities in public access for transfer and access of knowledge that is generated for the public weal (Beall, 2013). Particularly, having a limited access to the knowledge in early childhood studies is acknowledged as the first step for constitution of JCES. In this context, we would like to underline that independent researchers who are voluntarily taking part in the emergence of JCES are involved in a very courageous endeavour. This collective constitution takes an important responsibility for the public as well, and we point out that to fulfil this responsibility, it embraces moral and ethical rules as a reference point. Objectives, scope and ethical principles of JCES are determined with the contribution of the editorial board. In addition, we make promise to the larger research community of early childhood area that we will make sure to contribute to the area by giving a priority to high quality of research with robust evidence. JCES adopts open science perspective in early childhood studies. Therefore, JCES has a high opinion of sharing the knowledge among people who are in children’s ecology democratically. Attaching importance to open science policy, JCES defends scientific knowledge as public property that should be shared with all without depressing its value (Tonta, 2015). In the light of this target, -as JCES editorial board- we believe that scientific information that has been produced as public property should be shared with everyone through open access. The scientific communication enhanced between researchers-practitioners-readers is aimed to put into practice through the “open access” method. In this context, as open access policy within JCES, we embraced non-profit, voluntary editorial operations without charging a fee either from the reader or authors. Our experiences during publishing our first issue promise that it can be put into practice with a collective movement voluntarily on a digital platform. Solidarity is possible to carry out editorial process not only in Turkey but also with a contribution from every corner of the world. We have given extra importance to research ethics as our publishing policy. While specifying ethical principles, we aimed to take researcher’s attention to this issue. In this sense, after discussions with EECERA and then with the permission from Trustees of EECERA, we decided to embrace EECERA Ethical Code for Early Childhood Researchers that is formulated by Chris Pascal, Tony Bertram, Julia Formosinho, Colette Gray and Margy Whalley (2012). The ethical code bears qualification as a guide for researchers working in the early childhood area. We would like to indicate that applicant articles to the JCES are also evaluated in terms of those ethical codes during the editorial preliminary consideration process. After calling for papers for the inaugural issue, we had a considerable amount of article applications. Those applications studiously evaluated by the referees after preliminary considerations. In this process, constructive feedback from the referees and the revisions authors made in consideration to given feedback contributed to quality of articles concurrently to the quality of the journal. Peer review process that is held studiously, on time and constructively demonstrated that solidarity is built correctly and truthfully. Therefore, we would like to especially thank the referees for the inaugural issue. As you will see in the journal, there are six articles for the inaugural issue from five different countries: Belgium, Colombia, Israel,  Tanzania and the USA. This variety is a result of effective publicity of the journal by editorial board and efficient use of digital platforms with open access policy. Besides that, especially the call for papers announcements by EECERA in their member mail groups and social media accounts demonstrated once more how important solidarity is. As a result of this solidarity and cooperation, we would like to underline that the geographical variety of applicant articles strengthen our faith and self-confidence as well. After publishing first issue, we will continue pertinaciously working to strengthen international collaborations and to ensure continuity of the journal. Being aware of responsibility we are carrying and the risks we may face in the process, we would like to state that we have already taken necessary precautions. To ensure long running path and continuity of publishing for the journal, Gizem Alvan, Kerem Avcı and Taibe Kulaksız - doctorate students- have already started gaining experience in journal publishing and editorial administration process. These experiences would play an important role to provide sustainable publication of the journal. We would like to congratulate them to take part in a constitution courageously. We would like to thank all partners who contributed to spreading information to publish interest with open access with their articles and their supports in the editorial process for the inaugural issue. We would like to state that the call for papers continues for the second issue of JCES which will be published in August 2020 and we are open to early childhood researchers’ original contributions

    The drug-transporter gene MDR1 C3435T and G2677T/A polymorphisms and the risk of multidrug-resistant epilepsy in Turkish children

    Get PDF
    One-third of all individuals with epilepsy are resistant to antiepileptic drug (AED) treatment. Antiepileptic treatment response has been suggested to be modulated by genetic polymorphisms of drug efflux transporters. Several polymorphic variants within the multidrug resistance 1 (MDR1) gene, which encodes the major transmembrane efflux transporter P-glycoprotein, have been proposed to be associated with AED resistance in epilepsy patients. The aim of this study was to evaluate the effect of C3435T and G2677T/A polymorphisms of MDR1 on AED resistance in Turkish children with epilepsy. MDR1 C3435T and G2677T/A were genotyped in 152 patients with epilepsy, classified as drug-resistant in 69 and drug-responsive in 83. Genotypes of the C3435T and G2677T/A polymorphisms were determined by polymerase chain reaction followed by restriction fragment length polymorphism. Genotype and allele frequencies of C3435T and G2677T/A polymorphisms of the MDR1 gene did not differ between drug-resistant and drug-responsive epilepsy patients. Our results suggest that MDR1 C3435T and G2677T/A polymorphisms are not associated with AED resistance in Turkish epileptic patients. To clarify the exact clinical implication of the MDR1 polymorphisms on the multidrug resistance in epilepsy, further investigations in various ethnic populations would be necessary

    The Surgical Management of Hydatid Cyst of the Liver: What is New?

    Get PDF
    Liver hydatid cyst is a disease of zoonosis caused by Echinococcus granulosus or less frequently by Echinococcus multilocularis and Echinococcus oligarthrus. The primary carriers are canines, while human beings are secondary hosts. Early diagnosis is important for cysts not to become complicated and for the treatment not to get difficult. The most effective treatment of uncomplicated hydatid cyst is to reduce the dead space of the cavity and to discharge the fluid as much as possible. However, if the cysts get complex, there is no standard treatment management defined other than offered management options by authors. In complex conditions, the treatment is determined according to the stage of the cyst and the relation of the cyst with biliary ducts or surrounding organs. In this chapter, the treatment regimens of liver hydatid disease mainly based on interventions and surgical operations are going to take a part

    OBJECTIVE: The aim of this study was to compare the cytotoxic effects of endodontic cements on human tooth germ stem cells (hTGSCs). MTA Fillapex, a mineral trioxide aggregate (MTA)-based, salicylate resin containing root canal sealer, was compared with iRoot SP, a bioceramic sealer, and AH Plus Jet, an epoxy resin-based root canal sealer. MATERIAL AND METHODS: To evaluate cytotoxicity, all materials were packed into Teflon rings (4 mm”3 mm) and co-cultured with hTGSCs with the aid of 24-well Transwell permeable supports, which had a pore size of 0.4 ”m. Coverslips were coated with MTA Fillapex, iRoot SP and AH Plus Jet and each coverslip was placed onto the bottom of one well of a six-well plate for scanning electron microscopy (SEM) analysis. Before the cytotoxicity and SEM analysis, all samples were stored at 37ÂșC and at 95% humidity and 5% CO2 for 24 hours to set. The cellular viability was analyzed using MTS test (3-(4,5-dimethyl-thiazol-2-yl)-5-(3-carboxy-methoxy-phenyl)-2-(4-sulfo-phenyl)-2H-tetrazolium). The cytotoxic effects and SEM visualization of the tested materials were analyzed at 24-hour, 72-hour, one-week and two-week periods. RESULTS: On the 1st day, only MTA Fillapex caused cytotoxicity compared to negative control (NC) group (p;0.05). After 14 days of incubation with the test materials, MTA Fillapex exhibited significantly higher cytotoxicity compared with iRoot SP, AH Plus Jet and the NC group (

    Growing More Rice with Less Water: The System of Rice Intensification and Rice Productivity in Vietnam

    Get PDF
    We study the effects of a large-scale System of Rice Intensification (SRI) program on the water productivity of rice in Vietnam by exploiting the provincial and time variations in SRI uptake and irrigation water supply over the period 2000–2012. Our findings document that the world’s second-largest rice exporter could produce four million tons of more rice with same water supply in the reasonably achievable case of 20% SRI uptake across its provinces. In addition, we find that SRI increases the output of other crops too, due at least partly to its possible water savings and soil nutrition preservation in rice production. Moreover, we show that SRI is more likely to be adopted in provinces with stronger quality of provincial institutions and weaker agricultural capital base. Numerous selectivity and randomization tests affirm that the water productivity effect of SRI is robust to selection in SRI uptake at province and district levels and addressing potential unobservables and omitted variables problems

    Lack of Food Access and Double Catastrophe in Early Life: Lessons from the 1974–1975 Bangladesh Famine

    Get PDF
    We study the education outcomes of the 1974–1975 Bangladesh famine on early-life survivors using the 1991 Bangladesh microcensus data. We find that famine adversely affected the survivor children in areas that experienced higher rice prices relative to labour wage. In addition, children living in wealthy households in famine-stricken areas had better education outcomes than children with no famine exposure at all. We also find that, surprisingly, exposure to double catastrophe (i.e., concurrent famine and flood) in early life had weaker effects than exposure to single catastrophe. We show that disaster-alleviation mechanisms worked better in districts affected by double disasters
