Structural Stochastic Volatility

A novel closed-form pricing formula for short-maturity options is employed to jointly identify equity characteristics (spot volatility, spot leverage, and spot volatility of volatility) which have been the focus of large, but separate, strands of the literature. Interpreting equity as a call option on asset values, all equity characteristics should depend on structural sources of risk, such as the variance of the firm’s assets and the extent of the firm’s financial leverage. We confirm the implications of theory with data, thereby providing support for relations (like the link between spot leverage and the firm’s financial leverage) broadly considered empirically ambiguous.
Organizational Innovation Strategy Towards Small Medium Enterprise Performance in Malaysia

Small and Medium Enterprises (SME’s) are known to have large potential to be expanding to a higher level through innovation. New policies and incentives were developed and variety of programs provided by Malaysian Government, yet there are factors such as financial problem hampering them from implementing innovation. New generations of SMEs have to take the risk in innovations to meet the demand of the technology driven innovation economy. This study was undertaken to evaluate the implementation of organizational innovativeness among the Malaysian SME’s. The findings of this study indicate that different types of innovation have different impact towards organizational performance. Therefore willingness to embrace changes and having the right attitude at using knowledge and creativity to manipulate available information to develop the organizational strategies can assist SMEs in Malaysia to sustain and survive in the dynamic and challenging economy. In addition new generations of SMEs have to take the risk in innovations to meet the demand of the technology driven innovation economy.
Characterization of Japanese Raku Ceramics Using XRF and FTIR

Japanese raku ware is characterized by the use of lead glaz-es, short firing times, and rapid cooling, which give it its distinctive appearance. However, this also results in a high degree of heterogeneity because the firing is too rapid for the various components in the glaze to be made homogeneous. In this study of glazes from raku and associated wares, data from elemental analysis by X-ray fluorescence (XRF) spectroscopy, and from Fourier transform infrared (FTIR) spectroscopy using a fiber-optic probe, have been combined with observations of the glaze texture using a low-powered optical microscope and physical characteristics of color and foot shape.

Dividend Imputation and Optimal Tax Rates

Under the Australian dividend imputation system, there is wide variation in the proxies for tax aggressiveness amongst firms that pay franked dividends. This paper examines whether this variation is caused by tax-induced clientele and associated signaling by encouraging firms to target an optimal tax rate that will maximize the value of tax credits available to shareholders. Tests provide evidence of the existence of a targeted optimal tax rate that has both economic and statistical significance.

A Technical Review on Design & Thermal Behavior of Non-circular Hydrodynamic Journal Bearing using CFD Technique

The revolutionary changes have taken place in the field of hydrostatic and hybrid journal bearing from very slow speed radar to very high speed turbo machinery. These find application in ultra precision machine tools requiring high stiffness to improve accuracy. The growing demands from industries for higher speed applications and ability of hybrid journal bearing to support heavy loads have necessitated studying the performance of bearings in detail under more realistic conditions. However, the high speed operation of bearings results in higher operating temperature of both lubricant and bearing surface. Increase in bearing temperature poses a danger to bearing liner as well as to lubricant. It not only degrades the performance of a bearing but also of machine itself. Also, an increase in lubricant temperature reduces its viscosity and thereby changes the fluid-film profile

Teachers’ Knowledge and Belief on the CEFR Implementation in Malaysian ESL Classroom

The development of the Common European Framework of Reference (CEFR), has received widespread enthusiasm in language education. The CEFR has been used around the world for various purposes encompassing assessment, curriculum development and teaching purposes. Through comprehensive studies on the experiences of other countries that have implemented the CEFR, it is evident that the CEFR could enhance the English language teaching and learning process. Malaysia has currently implemented the CEFR in its English language education in an effort to align its system to the international standard so as to ensure that it is globally competitive. However, studies have shown that in order for a reform to achieve its intended goal, teachers‟ awareness and beliefs should be taken into account. Henceforth, a study is being carried out to investigate the implementation of the CEFR in the Malaysia English education system with a focus on teachers‟ knowledge and beliefs. This study utilized semi-structured interviews as the main data collection method involving English language teachers from different schools in Johor. The paper will be useful to gauge teachers‟ awareness on the CEFR implementation and contribute to the literature on the CEFR implementation in Malaysia.
WHITE PAPER: Safety Challenges of Autonomous Mobile Systems in Dynamic Unstructured Environments: Situational awareness, decision-making, autonomous navigation, & human- machine interface

Future autonomous mobile systems will be capable of operating in often unstructured and dynamic environment in a safe and meaningful manner and simultaneously work towards given mission objectives without being extensively controlled by human operators. In order to do that an autonomous system has not only to monitor its internal state but also sense, perceive, classify and model what is currently happening around it and even predict what will most likely happen in the near future. The requirement is the same be it a modern highly automated system working or transportation machine, an intelligent field and service robot or a next-generation oceangoing vessel. The current wide range of high-quality sensor systems available commercially-off-the-shelf together with well-matured multi-sensor fusion algorithms provide a solid foundation for that task. In addition, the system should be connected to any available supportive infrastructure (e.g., localization services, dynamic maps, etc.) and have tight interactions with other autonomous mobile systems sharing the same operation space. Furthermore, the autonomous mobile system should, at all times, in any condition, be fully aware of any human presence intended or unintended. The safety of humans must be ensured at any cost.

Incentive Thresholds , Performance , and Risk-Taking . Evidence from Hedge Funds

Managerial incentives induce risk-taking as well as effort. Theoretical research has long considered risktaking a potential side effect of incentives, but empirical investigation is limited. This paper uses exogenous variation in hedge fund manager’s incentives to examine both performance and risk-taking. I find, consistent with theory, that being farther below a key incentive threshold increases risk-taking and decreases performance. On average, a manager’s risk-taking increases 50% and their performance falls 2.1 percentage points when he is below the incentive threshold. I also show, consistent with the theoretical predictions, risk-taking behavior is non-monotonic; very distant managers take less risk and perform better than less distant managers. Further, I examine the role of organizational features in impacting the responsiveness to explicit incentives and the mechanisms managers use to increase risk. My results highlight the importance of risk-taking in response to incentives designed to induce effort and inform empirical research, contract design, practitioners, and policy makers. The results also show that moral hazard, not just selection, is an important determination of manager performance. * I am very grateful to Rui J. de Figueiredo, Steven Tadelis, and Catherine Wolfram for detailed comments.

Impact of Social Customer Relationship Management on Customer Satisfaction through Customer Empowerment: A Study of Islamic Banks in Kuwait

The aim of this study is to explore the impact of social customer relationship management (CRM) on customer satisfaction through customer empowerment using a sample of customers of Islamic banks in Kuwait. On the basis of the descriptive method, the required data were gathered using a questionnaire developed for the purpose of the present study based on previous relevant studies. A total of 700 questionnaires were distributed to the respondents. Out of these questionnaires, 613 questionnaires were returned complete. Particularly, 557 questionnaires were valid for statistical analysis. Basically, the results showed a statistically significant and positive impact of SCRM on customer satisfaction through customer empowerment. It was asserted that both traditional CRM and social media have significant effects on customer empowerment and satisfaction simultaneously. In view of the results of the study, it was recommended that banks should be interested in the social aspect of CRM and customer empowerment because in order to enhance customer satisfaction. The contribution of the present study is that it emphasized the importance of social relations management in customer satisfaction, especially in light of the role of mediating role of customer empowerment in Arabic financial settings.
The Times They Are A-Changin: Examining the Impact of Social Media on Music Album Sales and Piracy

The digital transformation of the music industry has changed the structure of the industry and consumers’ consumption patterns. Social media have become an integral part of the strategic and tactical decisions of artists. The magnitude of their importance is depicted by the fact that most artist-fan interactions are channeled in these media. This study examines the effects of different social media measures, aggregated out of user-generated as well as artist generated content, on music album sales across both physical and digital channels. We collected data from various social media platforms including Twitter, Facebook, and Lastfm for all music albums released in June 2013 in the US. We found that the volume of user generated content positively impacts both sales channels, whereas the valence of the content (analyzed through sentiment analysis) and user engagement positively impact only the physical channel. In addition, we considered not only user generated content, but also artist generated content (i.e., artist broadcasting) and found its significant and positive influence on physical sales. Furthermore, we examined the impacts of these social media metrics on music piracy in terms of illegal downloads. Notably, for post-release, volume, valence, and user engagement negatively affect illegal download, suggesting consumers are more likely to purchase a music album instead of pirating when there is a large amount of social media buzz. Finally, we found that volume has a significant and positive influence on physical sales only for independent label releases but not for major labels, whereas for major label artists it is crucial to actively participate in social media as depicted in the significant and positive value for broadcasting. This is one of the first studies to empirically assess the influence of various social media metrics on the success of a music album (physical sales, digital sales, and piracy). Our study offers artists and their managers a rather holistic view of the effects of social media content on album performance, and helps them to identify an album’s potential and to channel marketing budgets accordingly.
Brilliant Blue FCF as a Dye Tracer for Solute Transport Studies-A Toxicological Overview.

Brilliant Blue FCF (C.I. 42090) was found to be a useful dye tracer to stain the flow paths of water in soil media. Being neutral or anionic, it is not strongly adsorbed by negatively charged soil constituents. The dye is used in food because its general toxicity is low. However, to stain the flow paths of water in soil, fairly large concentrations are required to ensure good visibility of the tracer. Therefore, toxic effects cannot be entirely excluded, and assessing the environmental risk is a necessity, especially when field research is conducted in an environmental context. A literature review was carried out to compile data on Brilliant Blue FCF toxicity. The literature suggests that there is no carcinogenicity or mutagenicity to rodents. Brilliant Blue FCF does not accumulate in plants or animals, but degrades slowly in the environment. From the toxicological point of view the dye can be considered as a suitable and environmentally acceptable tracer for studying solute transport in soil, especially in the field.
Asset Pricing Theory with an Imprecise Information Set

This paper provides a novel theoretical platform for the pricing of imprecise accounting information as a systematic market risk. Our intertemporal asset pricing model shows that systematic information-quality risk is priced through a distinct market risk premium and three extra betas associated with an imprecise-information risk. Our first information-quality beta is related to the covariance between market-wide impreciseinformation return error and security precise return. Together with the separate market information-quality risk premium, this beta provides the theoretical underpinning for a separate market information-quality factor in the spirit of empirical multiple-factor model prevalent in the literature. The second extra beta (linked to the covariance between firm and market-wide imprecise-information return errors), represents the commonality in information quality, which is priced by investors seeking to curtail adverse effects of imprecise accounting information on their portfolio value. Our third information-quality beta (related to the covariance between stock imprecise-information return error and overall market return), implies that – for hedging purposes – investors prefer to invest in stocks issued by firms that tend to, erroneously or deliberately, release false positive information about the firm when the market is bearish. Our model is strongly supported by empirical evidence.
Design, Implementation, and Evaluation of a Real-Time Object- Oriented Database System

Recent works on Real-Time (RT) databases are focused on simulations. These studies present shortcomings not only in verification but also in comparison with existing core techniques used for the management of RT databases. Besides, RT database applications are challenged by the lack of an RT database system open source to perform a realistic environment. In this paper, a design based on a open-source object-oriented environment database system is proposed for the RT database application development. The proposed system is based on the RTQL (RealTime Query Language) which is defined as a high-level RT object-oriented query language. It supports the expression of timing constraints on data and it ensures transactions upon the data. Then, a QoS management approach is performed to reduce workloads and to detect overload. The proposed attempt is supported by the use of the feedback control RT scheduling theory. Our evaluation shows that our approach not only achieves the desired timeliness of transactions but also maintains high data freshness compared with other related approaches.
Self-Consciousness and Social Interaction Anxiety among School Students of Co-educational and Non-coeducational Schools of Lahore

The study aims at identifying a one-to-one correspondence among selfconsciousness and social interaction anxiety between students. Furthermore, the differences between coeducational and noncoeducational schools were also studied. Correlation research design and purposive sampling strategy was used to collect the data. A total sample of N= 200 participants were selected out of which 100 students were enrolled in coeducational, boys and girls, each (n= 50) and 100 participants who were enrolled in non-coeducational schools, boys and girls, each (n= 50) with ages ranging between 14-19 years old. The scales used in the research were The Self-Consciousness Revised Scale (Scheier & Carver, 1985) and Social Interaction Anxiousness Scale (Leary, 1983). Results suggested strong correlation among selfconsciousness both in public and private, as well as in social anxiety and social interaction anxiety. Moreover, no differences were found in relation to the self-consciousness and social interaction anxiety between the students enrolled both within coeducational and non-coeducational schools.
The Herding Effect of Domestic Investors on Foreign Investors: Evidence from the Iraq Stock Exchange

Financial market participants show biases over time. Herding is still one of the well-known biases. In developing or emerging financial markets, herding increases for domestic investors in relation to foreign investors’ behaviour. We study this effect on the Iraqi Stock Exchange. We found that local investors follow or ‘herd’ on foreign investors in many situations like forming portfolios, buy and sell signals, and in imitating their behaviour when less information is available for investments. Reasons behind that go back to domestic investors thinking foreign investors have enough skills and knowledge to make a better prediction about securities futures, because foreign investors have improved their experience from investments in developed countries, in addition to their enormous financial resources.
Economic crisis and youth unemployment in Europe: the role of regional specialization through a spatial quantile approach

European youth unemployment exhibits a contrasting image between the Northern and the Southern regions, which leads the analysis towards the drivers behind the spatial clustering of areas with low or high unemployment rates. The aim of this article is to provide some hints about the structural causes of the spatial distribution of youth unemployment growth during the recent crisis, using a Spatial Quantile approach at NUTS2 level. Results suggest that the similarity in the productive structure, the specialization in sectors with a higher concentration of young workers, or the working time flexibility had a different effect in those regions at the top or the bottom of the youth unemployment growth distribution, being this effect significantly different from the result of the global spatial estimation.
AQUEOUS COMPLEXES IN SEPARATIONS OF f-ELEMENTS: OPTIONS AND STRATEGIES FOR FUTURE DEVELOPMENT

Powerful and/or selective extractant molecules/sorbents are a necessary component of efficient metal ion separation processes. However, selectivity in extraction and efficiency in process design often rely on reactions occurring in or moderated by the aqueous medium. This report describes the role of the aqueous phase and reactions that occur in aquo in defining separation efficiency and metal ion selectivity. As the programmatic focus is on actinide solution chemistry, the separations chemistry of the f-elements will be used to illustrate the principal role of aqueous chemistry in metal ion separations. Most of the arguments developed apply to metal ion separations chemistry and processes in general. The discussion will emphasize the role of complexation and the effect of properties of the aqueous medium on separation efficiency and selectivity. Historically important separations processes will be considered along with recent efforts in the laboratories to design and characterize new water soluble complexants for improved f element separations.
