Entrepreneurs as parents : the antecedents and consequence of parenting stress

Purpose The purpose of this paper is to understand parenting stress of entrepreneurs and to attempt to extend the empirical evidence on the predictors and consequences of parenting stress for entrepreneurs. Design/methodology/approach This study draws on data from the Household, Income and Labour Dynamics in Australia Survey. The quantitative research method was used. Drawing on the data of 2,051 entrepreneurs, a model was tested using structural equation modeling. Findings The results reveal that social support is a strong predictor of parenting stress and that there is a direct effect between parenting stress and family to work interference (FWI). In addition, parenting stress partially mediates the relationship between social support and FWI. Adding a direct path from social support to FWI substantially improves the validity in a revised model. No effects of gender stereotypes are found. Originality/value This study attempts to extend previous work on parenting and vocational behavior by investigating the perceptional and stereotypical antecedents of parenting stress and examining the impact of parenting stress on FWI. To the challenges of parenting, many entrepreneurs face constant pressure to achieve a positive return in their business venture and work hard, for long hours. Therefore, a better understanding of entrepreneurs’ parenting roles and stress can shed some light on the challenges faced by self-employed individuals and contributes to the vocational behavior and career development literature and practical experiences

Analysis of intrusion prevention methods

Thesis (Master)--Izmir Institute of Technology, Computer Engineering, Izmir, 2004Includes bibliographical references (leaves: 105-108)Text in English; Abstract: Turkish and Englishviii, 108 leavesToday, the pace of the technological development and improvements has compelled the development of new and more complex applications. The obligatory of application development in a short time to rapidly changing requirements causes skipping of some stages, mostly the testing stage, in the software development cycle thus, leads to the production of applications with defects. These defects are, later, discovered by intruders to be used to penetrate into computer systems. Current security technologies, such as firewalls, intrusion detection systems, honeypots, network-based antivirus systems, are insufficient to protect systems against those, continuously increasing and rapid-spreading attacks. Intrusion Prevention System (IPS) is a new technology developed to block today.s application-specific, data-driven attacks that spread in the speed of communication. IPS is the evolved and integrated state of the existing technologies; it is not a new approach to network security. In this thesis, IPS products of various computer security appliance developer companies have been analyzed in details. At the end of these analyses, the requirements of network-based IPSs have been identified and an architecture that fits those requirements has been proposed. Also, a sample network-based IPS has been developed by modifying the open source application Snort

The curative effect of low molecular weight heparins on histopathological score of focal segmental glomerulosclerosis model

Son yıllarda fokal segmental glomeruloskleroz (FSGS) çocuklarda son dönem böbrek yetmezliği nedenleri arasında daha yüksek oranda yer almaktadır. Bu hastalığın yan etkileri yüksek olan steroid tedavisine ve diğer tedavilere yanıtı iyi değildir. Bu araştırmada amacımız FSGS tedavisi için yeni, yan etkisi düşük, etkili tedavi seçeneği ortaya koyabilmek düşüncesi ile deneysel olarak ratlarda düşük molekül ağırlıklı heparinlerin FSGS'da histopatolojik ve klinik olarak yararlılığını araştırmaktır. Deney altışarlı olmak üzere dört grup ile yürütüldü. Kontrol grubu sağlıklı ratlardan, ADR grubu 7,5 mg/kg adriyamisin verilen, PADR grubu adriyamisinden iki hafta sonra 15 gün steroid (5 mg/kg prednizolon) tedavisi verilen ve PADR grubu adriyamisin verildikten iki hafta sonra 15 gün süre ile düşük molekül ağırlıklı heparin (fraksiparin sodyum 2 mg/kg/gün) verilen gruplardan oluşmutu. Deneyin başında, 16. ve 31. günlerde kanda kreatinin, üre, protein, albümin, trigliserid, kolesterol, 24 saatlik idrarda protein ve kreatinin çalışıldı. Sakrifikasyon 31. günde yapıldı ve böbrek dokuları histopatolojik olarak değerlendirildi. Gruplar arası farklar tek yönlü varyans analizi, zamana göre karşılaştırmalar iki yönlü varyans analizi, histopatolojik veriler Pearson ki-kare exact testi ile istatistiksel olarak değerlendirildi. Adriyamisin verdiğimiz doz ve sürede ratların büyümesi ve beslenmesi etkilendi, nefrotik sendrom kliniği proteinüri, hiperlipidemi, hipoalbüminemi 15. günde oluştu, fakat böbrek fonksiyonlarında bozulma olmadı. Histopatolojik olarak glomerüllerde nekroz, konjesyon ve Bowman kapsül aralığında genişleme ve tübül epitelinde nekroz ve dejenerasyon, tübül çapında genişleme ile mezangial kollajen III birikimi saptandı. Ancak glomerüllerde skleroz, interstisyel alanda fibrozis oluşmadı. Düşük molekül ağırlıklı heparin ile verilen sürede ratların büyümesi gözlenmedi, idrar 24 saatlik proteini azalmadı, hipoalbüminemi ve hiperlipidemi düzelmedi. DMAH'in glomerüllerde nekroz, konjesyon ve Bowman kapsül aralığında genişlemeyi, tübül epitelinde nekroz ve dejenerasyonu, tübül çapında genişlemenin oluşmasını ve mezangial kollajen III birikimini önlediği saptandı. Sonuç olarak düşük molekül ağırlıklı heparinlerin adriyamisinle oluşturulan nefropatide 15 günlük sürede nefrotik sendrom kliniğine etki etmediği fakat histopatoloji üzerine yararı olduğu görülmüştür.Focal segmental glomerulosclerosis (FSGS) is one of the major causes of end-stage renal failure in children. The response of patients with FSGS to corticosteroids and other immunsuppressive therapies is poor. There is a need of a new, efficient therapeutic agent with limited adverse effects in FSGS. The aim of this study was to investigate the histopathological and clinical efficacy of low-molecular weight heparin in rats with experimentally-induced FSGS. The study consisted of 4 groups. Group ADR received adriamycin 7,5 mg/kg, group PADR received corticosteroids for 15 days two weeks after adriamycin administration, group HADR received low molecular weight heparin (fraxiparine sodium, 2 mg/kg/day, 15 days) two weeks after adriamycin administration and a control group involving healthy rats. Serum creatinine, urea, protein, albumin, trygliceride, cholesterol and daily urinary protein and creatinine were studied on days 0, 16 and 31. At day 31, all rats were sacrified and histopathological study of renal tissues was performed. Differences of the groups were established by univariate analysis, comparisons according to time by multivariate analysis and histopathological data by Pearson chi-square exact test. Data were presented as mean ' standard deviation; p<0.05 was accepted as significant. The growth and nutrition of rats were negatively affected and renal functions were preserved after administration of adriamycin. Signs of nephrotic syndrome as proteinuria, hypoalbuminemia and hyperlipidemia were observed at day 15. Likewise, histopathological examination revealed glomerular necrosis and congestion, enlargement of Bowman capsule, tubular necrosis, degeneration and enhancement, and mesangial collagen deposition; glomerular sclerosis and interstitial fibrosis were not seen. During the treatment period with low molecular weight heparin proteinuria, hypoalbuminemia and hyperlipidemia were not improved. However, in HADR and PADR groups glomerular necrosis and congestion, enlargement of Bowman capsule, tubular necrosis, degeneration and enhancement, and mesangial collagen deposition were similar to healthy control group.We conclude that low molecular weight heparin is beneficial on the histopathology of adriamycin-induced nephropathy

Eleştirel Düşünme Becerilerinin Geliştirilmesi

The aims of this research are to determine if the doctorate students of various institutes of Fırat University have critical thinking skills, and to find out if the two education courses, “Development and Learning” and “Planning and Assessment in Instruction” offered in the same term help to develop critical thinking. For this aim, “The Scale of Critical Thinking Skills” is used. The KMO (Kaiser- Meyer- Olkin) value of the scale is 0.75 and Cronbach Alpha Coefficient is 0.90. The results have revealed that the above mentioned courses help to develop critical thinking skills. It has been observed that students develop their critical thinking skills if they are encouraged to carry out research, to ask questions in the class, and to discuss issues in the classAraştırmanın amacı, Fırat Üniversitesi’ne bağlı bulunan enstitülerde doktora öğrenimi gören ve tez aşamasındaki öğrencilerin eleştirel düşünüp düşünmedikleri ve bir dönemde alınan “Gelişim ve Öğrenme” ile “Öğretimde Planlama ve Değerlendirme” öğretmenlik meslek bilgisi derslerinin eleştirel düşünme becerilerini geliştirip geliştirmediğini belirlemektir. Araştırmada, “Eleştirel (Kritik) Düşünme Becerileri Ölçeği” kullanılmıştır. Ölçeğin KMO (Kaiser-Meyer-Olkin) değeri 0.75, Cronbach Alpha güvenirlik katsayısı ise 0.90’dır. Araştırmanın sonucunda, iki öğretmenlik meslek bilgisi dersinin, öğrencilerin eleştirel düşünme becerilerini geliştirdiği görülmüştür. Öğrencilerin araştırmaya yönlendirilmesi, tartışma ve sorucevap şeklinde derslerin işlenmesi, derse katılımda ve soru sormada kendilerine güven duymalarının sağlanması gibi durumların, eleştirel düşünme becerilerini geliştirdiği düşünülmektedir
