İstanbul Menkul Kıymetler Borsası'nda haftanın günü etkisi ve Ocak ayı anomalilerinin ARCH-GARCH modelleri ile test edilmesi

Bu calismada, Istanbul Menkul Kiymetler Borsasi'nda (IMKB) haftanin gunu ve Ocak ayi anomalilerinin gozlenip gozlenmedigi arastirilmistir. Finans teorisinin ana kuramlarindan birisi olan Etkin Pazar Kurami'na aykiri dusen bu anomaliler uzerine pek cok calisma olmasina ragmen, IMKB'nin islem gordugu ilk gunden bu yana genis bir periyotu iceren ve GARCH modelleri ile anomali etkisini test eden fazla bir arastirmanin olmayisi, bu calismanin cikis noktasini olusturmaktadir. GARCH (1,1) modelinin kullanildigi ve bir gecikmeli getiri serisinin ortalama denklemde bulundugu IMKB Bilesik-100 Endeksi'nin 3 Temmuz 1987-18 Temmuz 2008 donemini kapsayan ve toplam 5157 gunluk veriden hareketle gerceklestirilen bu calismanin sonucunda, IMKB'nin Ocak ayi getirilerinde, diger aylara gore istatistiksel olarak anlamli bir sekilde herhangi bir farklilasmanin olmadigi tespit edilmistir. Bunun yanisira, Cuma gunleri IMKB endeksinin getirisinin diger gunlere oranla ortalamadan yuksek, Pazartesi gunu ise dusuk oldugu ortaya konmustur.
Sequence Biostratigraphy and Depositional Modelling of the Pennsylvanian-Permian Belloy Formation Peace River Embayment, Alberta Canada

The Pennsylvanian-Permian Belloy Formation within the Peace River Embayment (PRE) exhibits excellent reservoir potential and includes approximately 2% of the Western Canada Sedimentary Basin's (WCSB) proven oil and gas reserves. However, it is currently under explored. The formation has been largely overlooked as an exploration target because of difficulties with regional correlations and the lack of a basin wide sedimentological model. This presentation is part of an ongoing project that seeks to address these shortcomings utilizing conodont biostratigraphy and detailed core analysis. The PRE forms a fault-controll ed reentrant that dissected the North American cratonic margin during the Mississippian to Triassic. Previously, it was believed that the mixed carbonate and siliciclastic Pennsylvanian-Permian succession passively filled this embayment. However, it is becoming increasingly clear that block faults that disrupted the underlying Mississippian Stoddart Group also caused offset, differential synsedimentary subsidence and/or up doming in the Belloy. Eight depositional sequences have now been identified within the Belloy Formation. These sequences are being placed into a sequence biostratigraphic framework constructed through lithostratigraphic core based studies and conodont biostratigraphy. Lithofacies maps for each sequence have also been constructed that include previously unrecognized terrestrial sequences. Insights into the nature of the depositional system, in particular the potential tectonic control on lithofacies distribution will greatly enhance economically important exploration strategies and basin evolution models. A contemporaneous outcrop section at Tunnel Mountain, Banff has also been included in this study. This section, despite a markedly contrasting depositional environment from the PRE, has been successfully correlated into the subsurface with the use of outcrop gamma logging and the acquisition of sequence biostratigraphic data. The outcrop studies have extended the applicability of the sequence biostratigraphic framework to the entire WCSB indicating that regional relative sea level fluctuations are the primary control on sequence development for this interval.
The Influence of Christian Education on Leadership Development

This study was an exploration of the influence of Christian education on leadership development as perceived by people in leadership positions. A small, purposive sample of 10 individuals who are in some position of leadership and who received a Christian elementary and secondary education were interviewed regarding their perceptions of the influence of Christian education on their leadership development. The responses of the participants revealed four themes relevant to the purpose of the study: integration of Christian worldview, influence of teachers and coaches, academic experience, and activities. This study affirmed the importance of educational experience as a life experience, and supported the applicability of Clinton’s Leadership Emergence Theory as a model for evaluating leadership development that occurs in the educational process.
Molecular Taxonomy of Acetobacter syzygii SKU19 and Characterization of Its Acetic Acid Adapted Strains

Acetobacter species are one of the most suitable bacteria for the proteomic analysis of proteins involved in stress response or adaptation. Among 129 isolates of thermotolerant acetic-acid bacteria, two isolates SKU19 and SKU123 were selected as an acetic-acid sensitive and acetic-acid resistant strain, respectively. Molecular taxonomy of these isolates indicated that SKU19 and SKU123 were Acetobacter syzygii and A. pasteurianus, respectively. To elucidate an adaptive response to acetic acid, acetic-acid-adapted strains were isolated from sequential cultivations of the acetic-acid sensitive strain, A. syzygii SKU19, in a medium containing 1% acetic acid. The adapted variants could be divided into two groups based on their growth and ability to further oxidize acetate. The first group consisted of cells with increased overoxidation (rapid acetate oxidizers), while the second group contained cells with increased stability to acetate (slow acetate oxidizers). The membrane-bound quinoprotein alcohol dehydrogenase (PQQ-ADH) and aldehyde dehydrogenase (ALDH) activities of these adapted strains were higher than those of the wild type. The result corresponded well with the increased amount of protein with a molecular mass of 72-80 (subunit I) and 44-54 kDa (subunit II) when the organism was cultivated in a medium containing acetic acid. This study confirmed that acetic-acid resistance in aceticacid bacteria is conferred by several mechanisms, such as acetate assimilation and PQQ-ADH functions.

Single-Molecule Force Microscopy: A Potential Tool for the Mapping of Polysaccharides in Plant Cell Walls

Plant cells are surrounded by a polysaccharide-rich cell wall that, as well as being a supporting structure (O’Neill & York, 2003), plays important roles in plant growth and development, and in the protection of plants from both biotic and abiotic stresses (Bowles, 1990). Plant cell walls are also of global economic importance, with the cell walls of food crops being of great nutritional value, while those of agricultural crops are important as a renewable resource for the textile and building industries, and increasingly as a sustainable source of fuel (O’Neill & York, 2003).
Zeyve höyük-Porsuk. Bilan des recherches sur les niveaux du Bronze et du Fer

Ce site de Cappadoce meridionale, au pied de la chaine du Taurus, a fait l'objet de recherches archeologiques depuis la fin des annees 60. Fonde aux environs de 1600 aC, il est occupe durant toute la periode hittite, celle de l'ancien royaume comme celle de l'empire. L'un des interets du site est de presenter egalement, sous des niveaux hellenistiques et romains, une occupation de l'Âge du Fer, mais dont les debuts sont encore difficiles a fixer dans le temps de maniere precise, apres un hiatus consecutif a la destruction violente au Bronze Recent. Les recherches les plus recentes mettent surtout en lumiere l'importance inattendue de la periode hittite ancienne.
THE CYCLICAL BEHAVIOUR OF THE IPO MARKET IN AUSTRALIA

Initial public offerings have been examined typically in the context of short-term and long-run stock price performance of individual issues. In this paper, the aggregate market for IPOs is examined. There has been some prior suggestion that the IPO market exhibits cyclical patterns which are characterised by a high volume of new issues and substantial underpricing, such that 'hot issue periods' exist. This paper tests for the existence of such periods in the Australian market using a Markov regimeswitching model on a variety of constructed IPO activity measures. The results demonstrate that hot periods do exist but that they do not possess homogeneous features. A number of distinguishing features are also identified between industrial and resource sector IPOs. Further, a lead-lag relationship is identified for the industrial sector such that underpricing leads IPO volume for up to six months. The paper offers explanations for these findings that appear related to general stock market conditions and regulatory features.
Ashwagandha Root Extract Inhibits Acetylcholine Esterase, Protein Modification and Ameliorates H 2 O 2 -Induced Oxidative Stress in Rat Lymphocytes

Background: Herbs have long been the basis of medical treatment but the practice of herbalism is not strictly based on evidences gathered using scientific methods. Ashwagandha (Withania somnifera L.) is a traditional medicinal herb used in the treatment of various ailments. Objective: In current study we have evaluated the acetylcholine esterase (AChE) inhibitory and antioxidant potential of Ashwagandha root extract (ARE) in in-vitro and ex-vivo models to give a scientific base to its use in herbal medicine. Methodology: Simplest extraction e.g. maceration method was performed for preparation of extracts using methanol as solvent. Both in vitro and in vivo experimental trial were executed to evaluate the efficacy of root extract. Result and Discussion: ARE substantially scavenged free radicals and effectively prevented protein degradation as well as modification as studied by SDS-PAGE and Western blotting. Pre-treatment with ARE protected rat lymphocytes against H2O2-induced oxidative damage. H2O2 treatment resulted in DNA fragmentation and significantly decreased the activities of key antioxidant enzymes namely superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose-6-phosphate dehydrogenase while decreased and increased the content of glutathione and malondialdehyde, respectively. ARE pre-treatment almost reversed these changes indicating its efficiency to suppress hydrogen peroxide-induced oxidative stress. Conclusion: The study provides the scientific basis of pleiotropic functions of Ashwagandha.
Statistical properties of the solar wind

This paper presents some new and some updated data on the variation of the solar wind with solar cycle and distance from the Sun. The dynamic pressure of the solar wind is a minimum at solar maximum, the same time the standard deviation in pressure is a maximum, so the crossing of the termination shock is most likely at the next solar maximum in 2001. The degree of correlation between plasma parameters maximizes at solar minimum, possibly because stream interactions are a minimum then. The standard deviations of the radial velocity decrease rapidly out to 20 AU, then flatten out. Standard deviations of the density and temperature decrease with distance less steeply than those of the speed.
What You Can—and Can’t—Do With Three-Wave Panel Data

The recent change in the general social survey (GSS) to a rotating panel design is a landmark development for social scientists. Sociological methodologists have argued that fixed-effects (FE) models are generally the best starting point for analyzing panel data because they allow analysts to control for unobserved time-constant heterogeneity. We review these treatments and demonstrate the advantages of FE models in the context of the GSS. We also show, however, that FE models have two rarely tested assumptions that can seriously bias parameter estimates when violated. We provide simple tests for these assumptions. We further demonstrate that FE models are extremely sensitive to the correct specification of temporal lags. We provide a simulation and a proof to show that the use of incorrect lags in FE models can lead to coefficients that are the opposite sign of the true parameter values.
Development and Validation of a Stability Indicating HPLC Method for the Estimation of Butamirate Citrate and Benzoic Acid in Pharmaceutical Products

HPLC stability-indicating method has been developed for the simultaneous determination of Butamirate citrate and Benzoic acid in pharmaceutical dosage forms. Active compounds were separated on Zorbax SB-C8 column (250 mm × 4.6 mm, 5 μm Agilent) at an ambient temperature. Elution was performed with a mobile phase consisting of acetonitrile (solvent A) and a mixture of 10 gm of sodium lauryl sulphate and 5ml of 1 N sulphuric acid in 1000 ml distilled water (solvent B) at a ratio of 70:30 v/v and a flow-rate of 1.7 ml/min. Detection was performed with UV detector at 205 nm. Cough syrup preparation was subjected to long-term stability in order to demonstrate that storage conditions and degradants from both active compounds did not interfere with the quantification of Butamirate citrate and Benzoic acid. Typical validation characteristics such as linearity, range, precision, accuracy, and selectivity were evaluated for Butamirate citrate and Benzoic acid. Using the novel method, both Butamirate citrate and Benzoic acid were separated successfully. Validation studies demonstrated that the novel method possessed a linear UV response, good system precision and accuracy, high sensitivity and specificity for Butamirate citrate and Benzoic acid.
Changing responsibilities between home and school. Consequences for the pedagogical professionality of teachers

The pedagogical task of the school In the present social and educational debate on pedagogy, the moral task of the school, and the division of labor between home and school, it is often stated that parents, teachers and other socializing agencies in the community have shared responsibility for the education of the younger generation. The development of values, norms and citizenship has been high on the political and education agendas in the recent past. It is currently expected that education contribute to the necessary ‘restoration’ of values and norms in society by attending to moral education and creating a good pedagogical school climate and teachers functioning as a moral role model. It is sometimes pointed out that teaching is more than simply a profession, it is a calling (Hansen, 1995). Publications on the pedagogical assignment of the school clearly indicate that it is not only different tasks to be performed but also the possession and presentation of certain personality characteristics and even visible ‘virtues’. They also point to the fact that school, family and community should work together in nurturing and educating the youngsters. In the Netherlands the most important Advise Committee of the Government has been used, the African proverb, ‘It takes the whole village to raise a child’, to bolster arguments for greater cooperation between the families, school and community. While overused, the proverb does express the intent of a family/school/community partnership’. The partnerships are based on the notion that everyone is responsible for the education of the children, and by working together, all children will have a better chance to be successful. In the partnerships, the resources, or ‘energies’ of the various stakeholders are aligned so everyone is making a contribution to the common goal of learning. However, for the ‘whole village’ to be involved requires a concerted, sustained, collaborative effort. Family/school/community partnerships don’t just happen. They need to be planned, formed, and cultivated (Lueder 1998; Burke & Picus, 2001).
Tracing Public Opinion Propagation and Emotional Evolution Based on Public Emergencies in Social Networks

Social network has become the main communication platform for public emergencies, and it has also made the public opinion influence spread more widely. How to effectively obtain public opinions from it to guide the healthy development of the society is an important issue that the government and other functional departments are concerned about. However, the interaction and evolution mechanism between the subject and the environment in the public opinion propagation is complicated, and the public and media attention and reaction to the incident are closely linked with the progress of the incident disposal. And public mining corpus has some shortcomings in the distribution of emotional classification. Only the timely update of artificial rules and emotional dictionary resources, it can handle new text data well. In fact, from the perspective of public opinion propagation, this paper built the network matrix between Internet users through the forwarding relationship, and used the social network analysis method and the emotion mining analysis technology to study the interaction and evolution mechanism between the subject and the environment in the public opinion propagation, and it studied the role of users in the emotional propagation of social networks. This paper proposed a sentiment analysis method on the micro-blog platform, which expanded the emotional dictionary and took sentence and emoticon and sentence patterns into account, which improved the accuracy of positive and negative classifications and emotional polarity analysis of the micro-blog.
Effect of Vasicine, Vasicinone and Embelin on Some Important Targets of Plasmodium falciparum

Plasmodium falciparum, the most dangerous human malaria parasite, has 14 chromosomes, approximately 5,300 protein-encoding genes – almost two thirds of which appear to be unique to the organism – and about 208 genes known to be involved in the evasion of the host immune system. This genomic information can be used to exploit new chemotherapeutic targets, as well as antigens for potential vaccines. With scientific advancements, some promising targets are developed (Figure 6.1) e.g. malarial parasite protease inhibition, histidine rich protein (HRP2) inhibition, fatty acid biosynthesis (FAB) inhibition, plasmodium protein kinase inhibition, protein farnesyltrasferase inhibition for the malarial parasite control. With these tools in hand, phytomedicine research has a good chance of contributing to the development of new drugs for combating malaria (Pall & Shukla, 2003). Identifying compounds that bind to and modulate biological targets implicated in disease pathways is a fundamental step in the drug discovery process (Houston et al., 2008). This prompted us to investigate whether these isolated compounds have any effect on different targets of malarial parasite and to establish the probable mechanism of action.
An open source head-eye tracking suite for immersive environments: Point of Regard

Immersive environments offer significant potential for engaging users in new ways of receiving information and learning. Although, commercial head-eye trackers offer advantages when compared to Open Source Software (OSS) solutions, their use for research presents the same problem as many proprietary software and hardware: restricted access to data and protocols. To overcome these problems, this paper describes the development of OSS which was designed to be used with either commercial or open source hardware. Particular focus was on designing the software from the ground up, to work with immersive environments. As a result, the Point of Regard (PoR) head-eye tracking software uses an open source library which takes as data input a users' head position, head orientation and eye data from any device giving the freedom to the developer for manipulating the resulting combined data.
Digitalization Challenging Institutional Logics: Top Executive Sensemaking of Service Business Change

Purpose The purpose of this paper is to explore the mental models of top executive team members in a selected retail bank. The focus is on how each executive team member makes sense of the market situation and changes with regard to customers and customer-bank interactions in the current situation where earlier bank practices are at risk of becoming obsolete. Design/methodology/approach All members in the executive team were interviewed individually in August 2014 on how they reason about challenges in the service business. The study uses an abductive research approach. Findings The mental models were largely dominated by internal bank issues, and adjusting the services to changing customer preferences was considered a main challenge. The research analysis showed that the executive team members identified the same business challenges, but their interpretations of the meanings and implications of the challenges were different. Mental models tend to be hidden and stable and are seldom explicitly elaborated. There was a distinct spread in mental models in terms of content. Limited focus was on customers as the starting point for business development and renewal. Research limitations/implications The study was conducted in the retail banking setting, which is currently affected by many changes. The study, however, was limited to executive members in one bank. Practical implications The foremost implications of this study relate to sensitising executive members and teams to their mental models and exposing different core challenges related to customers and customer relationships in the retail banking sector. Originality/value The value of the study is it sheds light on top executives’ prospective sensemaking of current business challenges by addressing individual mental models. The study represents a novel approach in the strategic service management literature.
