Estimating Financial Trends by Spline Fitting via Fisher Algoritm

Trends have a crucial role in finance such as setting investment strategies and technical analysis.  Determining trend changes in an optimal way is the main aim of this study. The model of this study improves the optimality by spline fitting to the equations to reduce the error terms. The results show that spline fitting is more efficient compared to line fitting by % and Fisher Method by %. This method may be used to determine regime switches as well

The Estimation of Acidic Behavior of Wood by Treatment with Aqueous Na2HPO4 Solution

As a new approach, the acidity that wood exhibits under moderate conditions is assayed by stimulated dissociation of weak wood acids in lightly basic secondary phosphate solutions. To assure a sufficient dissociation of hardly soluble weak acids in the solution, the amount of wood suspended in Na2HPO4 solutions should be small but vary depending on the degree of acidity of wood species. However, the difficulties are associated with the titration of very dilute acids limiting the precision of the measurement. If the disintegrated wood is suspended in a secondary phosphate solution, the weak woods acids form the conjugate acid Na2HPO4 from secondary phosphate Na2HPO4 resulting in a pH fall of the solution. The decrease in the pH value in phosphate solution, which depends on the wood acidity, can be evaluated to estimate the acidity arising from wood under moderate conditions

Book of Abstracts of the Sixth SIAM Workshop on Combinatorial Scientific Computing

Book of Abstracts of CSC14 edited by Bora UçarInternational audienceThe Sixth SIAM Workshop on Combinatorial Scientific Computing, CSC14, was organized at the Ecole Normale Supérieure de Lyon, France on 21st to 23rd July, 2014. This two and a half day event marked the sixth in a series that started ten years ago in San Francisco, USA. The CSC14 Workshop's focus was on combinatorial mathematics and algorithms in high performance computing, broadly interpreted. The workshop featured three invited talks, 27 contributed talks and eight poster presentations. All three invited talks were focused on two interesting fields of research specifically: randomized algorithms for numerical linear algebra and network analysis. The contributed talks and the posters targeted modeling, analysis, bisection, clustering, and partitioning of graphs, applied in the context of networks, sparse matrix factorizations, iterative solvers, fast multi-pole methods, automatic differentiation, high-performance computing, and linear programming. The workshop was held at the premises of the LIP laboratory of ENS Lyon and was generously supported by the LABEX MILYON (ANR-10-LABX-0070, Université de Lyon, within the program ''Investissements d'Avenir'' ANR-11-IDEX-0007 operated by the French National Research Agency), and by SIAM

Consumers' attitudes towards advertising in general

Tutumlar insan davranışı üzerinde belirleyici olmasından dolayı reklamcılık alnında da ilgi görmektedir. Çünkü bireyin reklamcılığa yönelik tutumu, reklamın iletişim etkisi üzerinde belirleyici olabilmektedir. Reklamcılığa yönelik genel tutumları inceleyen çalışmalar ele alındığında, bu çalışmaların ağırlıklı olarak nicel araştırmalar olduğu, nitel çalışmaların ise sınırlı olduğu anlaşılmaktadır. Bu çalışmanın ana amacı bireylerin reklamcılığa yönelik genel tutumlarını ve bu tutumların altında yatan nedenleri ortaya koymaktır. Bu doğrultuda farklı sosyo-ekonomik düzeyden otuz katılımcı ile yarı yapılandırılmış görüşme gerçekleştirilmiştir. Katılımcıların reklamcılığa yönelik tutumları betimsel analiz yöntemi ile değerlendirilmiş ve tutumlar olumlu, olumsuz ve çift yönlü tutumlar olmak üzere sınıflandırılmıştır. Araştırma sonuçlarına göre ekonomiye katkı sağlama, bilgilendirme ve eğlendirme işlevleri reklamcılığa yönelik olumlu tutumlar üzerinde belirleyicidir. Reklamcılığa yönelik olumsuz tutumlar üzerinde ise reklamların çok uzun sürmesi, sık tekrar etmesi, yayını bölmesi, gençler ve çocuklar üzerindeki olumsuz etkisi, alım gücü yetersiz insanları özendirmesi, tüketiciyi yanıltması ve tüketimi teşvik etmesi unsurlarının belirleyici olduğu anlaşılmıştır. Since attitudes affect human behavior to a great extent, it has been an area of interest of advertising field. In addition, the attitude of individuals towards advertising is a determinant on communication effect of advertisements. When the studies focusing on general attitudes toward advertising are examined, it is seen that they are mostly qualitative studies. This study mainlyaims to explore the general attitudes of individuals towards advertising and the reasons lying behind these reasons. For the purposes of the study, semi-structured interviews were conducted with 30 participants from various socio-economic backgrounds. The attitudes of the participants towards advertising were analyzed through descriptive analysis method and these attitudes were classified into three groups; positive, negative and two-way. According to the findings, the following issues determine positive attitudes towards advertising: contribution to economy; information provision and entertainment. As for the determining factors on negative attitudes on advertising, the following issues can be listed: long advertisements, frequent appearance; barging into ongoing broadcasts such as films or TV series; the negative effects on children and young people; tempting people with low income to buy the product; misleading the potential consumers; and encouraging the purchase of the product

Self-presentation and gender roles on Facebook

Günümüzde hızla gelişen internet teknolojileri toplumsal cinsiyet rollerine yönelik sunumların incelenmesi için yeni bir mecra olarak karşımıza çıkmaktadır. Bu çalışma, bir sosyal paylaşım sitesi olan Facebook’ta benlik sunumunu toplumsal cinsiyet rolleri açısından ele almaktadır. Bu doğrultuda Facebook kullanıcılarının profil ve kapak resimleri incelenmiştir. Facebook profilleri uygun gelen örneklem yöntemi ile belirlenmiş olup veriler içerik analizi yöntemi ile toplanmıştır. Bu kapsamda 464 Facebook kullanıcısına ait profil ve kapak resimleri incelenmiştir. Araştırma sonuçları yaş ve medeni durum değişkenlerine göre cinsiyetler arasında profil ve kapak resmi özellikleri açısından anlamalı farklar olduğunu ortaya koymuştur. Nowadays, rapidly developing internet technologies appears as a new medium to examine self-presentation for gender roles. This paper discusses self-presentation on Facebook, a social networking site, in terms of gender roles. In this sense Facebook users’ profile and cover pictures were analyzed. Facebook profiles were determined by convenience sampling method and data were collected by content analysis method. In this context profile and cover pictures of 464 Facebook users’ were analyzed. Results show that in different age groups and marital status there are significant differences between genders with regards to features of profile and cover pictures
