Capital Asset Pricing Model (CAPM) Testability and its Validity in Stock Market: Evidence from Previous Literatures

Stocks such as bonds, treasurers and common stocks have been used in many companies to raise capital and improve investment for the benefit of the company or individual. Many companies has been raising or buying stocks for the investment benefit. Manager’s decisions about stock pricing, stocks rising, stocks purchasing, investment valuation, etc have depended on market situation of such period in particular. As we know that managers or individuals cannot expect to succeed without understand how market forces shape the firm’s ability to earn profit. Therefore, risk and return which associated with stocks have been given attention with companies and individuals, which was the cause of establishment of many models for these evaluations. One of the modal is Capital Asset Pricing Model(CAPM) which has became useful for assessment of cost of capital, portfolio performance, and portfolio diversification, valuing investments, choosing portfolio strategy among others and relationship between risk and return in market portfolio. The aim of this paper is to identify the validity of CAPM by thoroughly reviewing the literature and seeing whether its assumptions which used to guide its usage are holding true. Methodology used; CAPM is discussed under four categories which are the CAPM as a single factor model, supportive evidence of the CAPM evidence against it through various literatures. Findings showed that the CAPM remains a very useful item in the investment management toolkit. And investors trust it to evaluate the profitability of projects. Keywords : Risk, Return, Portfolio, Asset, Validity, market, CAPM’
Quantifying Impact of Aging Population on Fiscal Space

This paper quantitatively investigates how population aging trend affects fiscal space measured as unused revenue generating capacity by utilizing a standard neoclassical growth model. A calibration exercise for G-7 countries shows that France, Germany and Italy suffer greater revenue impact from a given reduction in hours worked due to their larger government expenditure. Corrective measures such as pension reform and flexible expenditure policy would be required in order to mitigate the impact of aging on fiscal space.
Career Planning as a Building Block for Personal Excellence

Abstract The narrow field of research here is the development of a model for the building of personal excellence using a career plan that is empirically tested and confirmed, both qualitatively and quantitatively. The purpose of this study relates to the writing of a career plan, for the determination of the factors that influence the feeling of personal excellence of participants in career planning education, in relation to other participants who are not. The qualitative analysis consists of basic experience data that was collected during the education process, through 20 essays, and the paradigmatic model, with the final theory defined, and based on this, a questionnaire was created. The quantitative analysis involved a total of 547 participants. For the statistical analyses of the data, bivariate analysis was used to assess the linear connection of individual pairs of variables. The search for differences between the two groups used t-tests for independent samples. Factor analysis was used to determine whether the relations among the examined variables can be explained with a smaller number of indirectly examined variables. The final model consists of three elements: (1) relation with career; (2) self-esteem; and (3) perception of personal excellence. Management can use the results of this study for management decisions. The increased success of every individual organisation benefits the whole of society. This study represents an original contribution and offers a new approach that is based on the paradigm of the understanding of a career and the importance of its planning as a motive for excellence.
Self-Organization And Self-Management In Control-Flow Error Mitigation

: This paper presents a software-based technique to mitigate Control-flow Errors (CFEs) in multithreaded programs. In this paper, we concentrate on self-organization and self-management mitigation of control-flow error using additional instructions insertion into specific portions of multithreaded program at design time regarding to control-flow and data-flow dependency graphs. In order to evaluate the proposed technique, three multithreaded benchmarks quick sort, matrix multiplication and linked list utilized to run on a multi-core processor, and a total of 5000 transient faults has been injected into several executable points of each program. The results show that this technique detects and corrects between 91.9% and 93.8% of the injected faults with acceptable performance and memory overheads.
ISOLATION, BIOTYPING, AND SEROTYPING OF YERSINIA ENTEROCOLITICA STRAINS FROM FATTENING PIGS

The study has been taken up to collect more data on Yersinia enterocolitica isolated from pigs as the main reservoir and source of infection with strains pathogenic for humans. Bacteriological examinations, bio- and serotyping were conducted on 616 rectal swabs, taken from 308 fattening pigs. Two samples were taken from each animal to determine the ability of Y. enterocolitica to grow under different temperature conditions (warm and cold culture). It has been proven that low temperature constitutes a suitable culture condition. 138 Yersinia enterocolitica strains were isolated (22.40%), most of which (65.22%) were obtained in cold culture and 99.28% included in biotype 3 (one strain belonged to biotype 2). Serotyping yielded a positive result in 107 strains with the diagnostic serum for antigen O:3, in 18 – with the serum for antigen O:9, and 13 strains were determined to be non-typable. The results indicated that asymptomatic infections with Y. enterocolitica strains of the biotypes and serotypes pathogenic for humans are common in pig population.
Artifacts Removal of EEG Signals By the Application of ICA and Double Density DWT Algorithm

Independent Component Analysis is used for the automation and detection of brain artifacts. The Independent Component Analysis (ICA) here is used for the segmentation of artifact peaks in the signal. Then the Discrete Wavelet Transform is applied for multi-level transfer of signal data until the reception of significant result. We have extended our search and applied the Double Density Algorithm for the multi-level transfer. The results obtained were analyzed from the data set of EEG signals taken with a outsource reference. Since the method is parameter free implementations in clinical settings are imaginable.
Impact of differential storage conditions on seed germination and viability of some medicinal plants

The present study describes the impact of different storage comportments on germination and viability of seven plant species of ethno-medicinal importance in Chhattisgarh state of India. Seeds were subjected to various storage environments (room and low temperature); storage types (polythene bag, cloth bag, aluminum foil, paper bag) and storage durations (3, 6 and 9 months). Observation on germination percentage clearly indicated that at room temperature poly bag was found to be most suitable for storage compared with other materials whereas, under low temperature aluminum foil tend to be most ideal for seed storage. Seeds stored in cloth bag were found with least germination percentage among the tested plant species. Irrespective of plant species, germination percentages were significantly higher when seeds are stored in room temperature. Interaction between storage conditions, type of storage and plant species on the viability of seed was also found to be significant. It was interesting to note that seed germination percentage varied within seven plant species collected from different wild habitats. Further studies on important medicinal plant species would be useful to optimize the storage components. The data also exert implications for conservation of tested medicinal plant species in respect to proper seed storage.
A tale of two countries: a directed technical change approach

It is widely recognized that scientific research has a dramatic impact on economies since it is crucial to foster technological knowledge. Today’s migratory movements and concentration of highly educated population and population with high scientific potential in developed countries play an essential role in enhancing research and boosting economic growth. We propose a North-South model that encompasses these empirical facts and proposes explanatory mechanisms. We show how the technological-knowledge gap is hard to reverse, namely when, due to higher returns, the majority of scientists are concentrated in the North. The implications of having either perfect- or no-labour mobility between countries are studied. In addition, it is showed the effect of complementarity or substitutability of goods on scientists’ incentives may allow countries to avoid a poverty trap. The calibrated model provides consistent dynamics with actual data. Scientists’ incentives are highlighted as the main source of divergence or convergence between countries.
Relationship between Middle School Students’ Frequency of Participation in Lab Activities and Scientific Epistemological Beliefs: Turkish Case

The purpose of this study is to investigate relationship of fifth, sixth, seventh and eighth grade students' scientific epistemological beliefs with their frequency of participating in laboratory activities. For this purpose, correlational study method was used. Sample of the study involved 301 students purposively selected from convenient schools. The data of the study was collected by a Likert type scale called "Scientific Epistemological Beliefs Scale" and information form about frequency of participating in laboratory activities and description of sample laboratory activities. The findings showed that majority of the students never participated in lab activities or participated in one time during one year. Also the fifth, sixth, seventh and eighth grade students' scientific epistemological beliefs were significantly related to their frequency of participating in laboratory activities. They are positively correlated to each other. However there were no significant relationships between the students' scientific epistemological beliefs and their frequency of participating in laboratory activities. Hence it can be claimed that participating in lab activities is associated with development of sophisticated scientific epistemological beliefs.
Political elections, abnormal returns and stock price volatility: the case of Greece

The impact of the Greek political elections on the return and volatility of the Athens Stock Exchange (ASE) is investigated using both the standard event study methodology and various univariate GARCH models. The empirical results reveal positive pre- and post-election abnormal returns, but negative on the day of the election. Strong evidence is also found that suggests that the election outcome significantly affects the ASE return; however, the evidence is rather limited for the ASE volatility. The empirical findings raise doubts about the efficiency of the Greek stock market and might have important implications for investors with respect to decisions regarding entering and/or exiting the market or investment strategies around time periods where political elections are going to take place.
Survay on Job Scheduling, Load Balancing and Fault Tolerance Techniques for Computational Grids

Computational grid is a network of loosely coupled, heterogeneous and geographically-dispersed computers acting together to perform a large compute-intensive job. In this article, we focus on the existing approaches to grid scheduling, load balancing and fault-tolerance problems. Although grid scheduling, load balancing and fault tolerance are active research areas in grid computing, these areas have largely been and continue to be developed independent of one another each focusing on different aspects of computing. Hence, in this survey, we hope to show that robust applications that can provide efficient results can be designed by collectively considering these areas. To this end, we first provide an introduction to the motivation, grid scheduling, load balancing and fault tolerance concepts of grid computing and discuss the works that have provided significant contributions to each of these areas since its inception until 2013. We discuss their advantages, disadvantages and analyze their suitability for usage in a dynamic grid environment. We conclude that, while important advancements have been made in each of these areas individually, high performance approaches that cumulatively consider these areas still remain to be explored. We also discuss the research work that is missing and what we believe the community should be considering. To the best of our knowledge, no such survey has been conducted in the literature up to now.
Predicting decadal trends and transient responses of radiocarbon storage and fluxes in a temperate forest soil

Representing the response of soil carbon dynam- ics to global environmental change requires the incorporation of multiple tools in the development of predictive models. An important tool to construct and test models is the incor- poration of bomb radiocarbon in soil organic matter during the past decades. In this manuscript, we combined radiocar- bon data and a previously developed empirical model to ex- plore decade-scale soil carbon dynamics in a temperate for- est ecosystem at the Harvard Forest, Massachusetts, USA. We evaluated the contribution of different soil C fractions to both total soil CO2 efflux and microbially respired C. We tested the performance of the model based on measurable soil organic matter fractions against a decade of radiocarbon measurements. The model was then challenged with radio- carbon measurements from a warming and N addition exper- iment to test multiple hypotheses about the different response of soil C fractions to the experimental manipulations. Our results showed that the empirical model satisfactorily pre- dicts the trends of radiocarbon in litter, density fractions, and respired CO2 observed over a decade in the soils not sub- jected to manipulation. However, the model, modified with prescribed relationships for temperature and decomposition rates, predicted most but not all the observations from the field experiment where soil temperatures and nitrogen levels were increased, suggesting that a larger degree of complexity and mechanistic relations need to be added to the model to predict short-term responses and transient dynamics.
Removal of the periplasmic DNase before electroporation enhances efficiency of transformation in the marine bacterium Vibrio alginolyticus

We have established a reliable procedure for electroporation in the marine bacterium Vibrio alginolyticus. Plasmids carrying the P15A replicon were found to be stably maintained in the Vibrio cells, and chloramphenicol, kanamycin or tetracycline were used for selection. Since we found that the Vibrio cells excrete DNase into the culture medium, cells were subjected to osmotic shock before extensive washing in order to remove the DNase from the periplasmic space. This manipulation resulted in about a 10-fold increase in the efficiency of transformation. In addition, cells were washed in the presence of 5-10 mM Mg2+in order to stabilize the outer membrane. The efficiency of transformation was found to be optimal when cells were harvested at early stationary phase, and when electroporation was carried out at an electric field strength between 5-0 and 7.5 kV cm-1. Under optimal conditions, about 105transformants per μg of input DNA were reproducibly obtained, which is tolerable for cloning.
Antibacterial activity of isolated human intestinal microbiota Lactobacillus strains against methicillin resistant and susceptible Staphylococcus aureus

In the present study, lactic acid bacteria were screened for anti-methicillin resistant activity. Isolation of lactic acid bacteria from 100 faecal samples of healthy adults was conducted using de Man-Rogosa Sharpe agar (MRS) and three Lactobacilli strains were isolated. The three isolates of human intestinal microbiota were identified on the basis of morphological and biochemical characteristics. The incidence of Lactobacillus plantarum, Lactobacillus acidophilus and Lactobacillus casei were found to be 43.47, 34.78 and 21.73% respectively. The antibacterial activity of these three isolates was determined against five strains of Staphylococcus aureus, including three methicillin resistant Staphylococcus aureus strains. Maximum inhibitory potential was seen in L. casei. Therapeutic efficacy of the lactobacilli strains was evaluated to control the re-emerging MRSA infection.
Construction of infectious full-length cDNA clones of apple viruses and plant viral vector development

Apple chlorotic leaf spot virus (ACLSV) and Apple stem pitting virus (ASPV) are important viral pathogens in apple. The aim of the present work was to construct full-length cDNA clones of ACLSV and ASPV and to agroinoculate apple seedlings with the constructed infectious clones using a newly developed vacuum infiltration method. A further goal was to explore and create viral vectors based on the obtained infectious full-length cDNA clones of ACLSV. In the thesis, the full-length cDNA clones of ACLSV and ASPV were constructed using different methods. The methods contained circular polymerase extension cloning (CPEC), Gibson assembly and In-Fusion cloning. In total 17 full-length cDNA clones of ACLSV and ASPV were obtained. Four of the 17 clones were infectious on Nicotiana occidentalis 37B, i.e. pIF3-15, pIF3-19, pIF14-23 and pIF4-4. The viral genomic cDNAs in these infectious clones were completely sequenced, and the sequence data were analyzed by alignment with published sequences in NCBI. The results indicated that three isolates of ACLSV were rescued: ACLSV isolate 38/85A (pIF3-15), 38/85B (pIF3-19) and (36)/88 (pIF14-23). One ASPV isolate was rescued: ASPV 40/87. A protocol of agroinoculation of apple seedlings by vacuum infiltration was developed to inoculate the infectious clones (pIF3-15, pIF3-19, pIF14-23 and pIF4-4) to apple seedlings. In the protocol, the treatment of seedlings, preparation of inocula and parameters of vacuum infiltration were evaluated. The highest PCR-positive rate (infection) of 78% (11/14), 100% (11/11), 25% (2/8) and 50% (9/18) were observed for the infectious clones of pIF3-15, pIF319, pIF14-23 and pIF4-4, respectively. The infection of virus was determined by RT-PCR. The existence of viral particles in PCR-positive plants was determined by immunosorbent electron microscopy. To explore and develop plant viral vectors based on ACLSV, marker genes of Emerald GFP, mCherry or iLov were inserted into the genomic cDNA of ACLSV. Nine plasmids with marker genes were constructed using three different strategies, including pIF13-9, pIF18-2, pIF25-7, pG11-15, pIF24-6, pIF23-1, pIF16-1, pIF20-16 and pIF27-10. After agroinoculation of N. occidentalis 37B with the constructed plasmids, it was found that deletion of marker genes in pIF13-9 and pG11-15 occurred due to homologous recombination between duplicated fragments of ACLSV genomic cDNA. Typical ACLSV symptoms were observed on the test-plants inoculated with pIF13-9 and pG11-15. By western blot, viral proteins of CP of identical size with wild type virus (pIF3-19) were detected for the two constructs in symptomatic plants. In one trial in winter, the pIF25-7 caused systemic infection in one plant. The other plasmids of pIF18-2, pIF24-6, pIF23-1, pIF16-1, pIF20-16 and pIF27-10 did not cause local or systemic infection in any test-plant.
A Novel Multilevel Inverter Employing Additive and Subtractive Topology

As the demand for high voltage, high power inverters are increasing and there is a problem of connecting a power semiconductor switch directly to a high voltage network. As a part of this the multilevel inverters had been introduced. As a part of this, several researches had been done for the development of multilevel inverters. The commercially available and extensively studied topologies for multilevel voltage output are Neutral Point Clamped (NPC), Cascaded Half Bridge (CHB) and Flying Capacitor (FC) converters. However, with these existing topologies, there is a significant increase in the number of power switches and passive components. Thus it leads to more complex control circuitry and overall cost of the system increase with increase in the output levels. In this paper, a novel multilevel inverter is proposed in which it employs additive and subtractive topology to get higher output levels. This approach significantly reduces the number of power switches needed as compared to existing topology. The present developed multilevel inverter can generate only five voltage levels. With this proposed topology the multilevel inverter can be modified to nine-level inverter. Moreover modified hybrid multicarrier Pulse Width Modulation (PWM) technique can be implemented in the proposed multilevel inverter in order to obtain uniform switch utilization and lower THD. An appropriate modulation scheme is presented and also the proposed concept is analyzed through simulation studies.
Agricultural Shocks and Riots: A Disaggregated Analysis

Every year, riots cause a substantial number of fatalities in less-advanced countries. This paper explores the role of agricultural output shocks in explaining riots. Our theory predicts a negative relationship between the level of rioting and the deviation of the actual output from the average one. Relying on monthly data at the cell level (0.5×0.5 degrees), and using a drought index to proxy for output shocks, our empirical analysis confirms such a negative relationship for Sub-Saharan Africa: A one-standard-deviation decrease in the drought index rises the likelihood of a riot in a given cell and month by 8.4 percent. The use of highly disaggregated data accounts for the fact that riots are temporally and geographically confined events.
Cuminum cyminum L. fruits distillate ameliorates the high fat diet-induced obesity

Introduction: Cuminum cyminum L. (Fam. Apiaceae) is a widely consumed spice. It is a rich sources of essential oils and has been actively researched for its chemical composition and biological activities. Aims: The study aimed to investigate the antiobesity effects of Cuminum cyminum L. distillates (CD) in high-fat-diet-induced obese rats. Methods: Twenty four male rats were randomly assigned to one of four groups: normal diet (ND), high fat diet (HFD), HFD + CD and HFD + orlistat. The CD was administered orally 7.75 ml/kg/twice a day for 4 weeks. Results: The CDtreated group significantly (p < 0.001) decreased the body weight gain, fat-pad weights, serum and hepatic lipids levels, insulin, glucose, leptin and pancreatic lipase activity in HFD-induced obese rats. The histological analysis revealed that the CD-treated group showed a remarkable reduction of macro vesicular steatosis in hepatic tissues and a significantly decreased number of lipid droplets and size of adipocytes compared to the HFD group. Conclusions: These findings demonstrate that CD treatment has a protective effect against a high-fat-diet-induced obesity in rats through the decreased activity in lipogenesis, as well as the increase in fatty acid oxidation and reduced intestinal absorption of dietary fat.
