abstract = {This study attempts to add to the small body of existing literature relating Chief executive officer characteristics to earnings management. Our research was carried out on 153 French listed companies during 2008. Using discretionary accruals as a proxy for earnings management, we found a significant positive relationship between CEO characteristics and earnings management. This suggests that since reputed CEOs are well compensated, they are more afraid to lose thier compensation level, and their incentive to manipulate their firm's earnings therefore increases. Findings also indicate that the dual CEO-chair relationship encourages CEOs to manage earnings, particularly when CEO-chairs hold the major proportion of equity in the firm. This finding suggests that CEO-chairs use their managerial power and the freedom from control to extract private yields. Finally, we present new on the relationship between CEO expertise and earnings management, showing that expertise positively affects CEO's behavior leading to their using agressive earnings management},

As the results of the research are based on a comparative analysis of differences and peculiarities in talent practices in Russian and foreign companies, the paper explores and provides a number of ideas and conclusions about talent management elaboration, realization and talent practices improvement in the Russian context. Our data show that talent management practices are influenced by a number of factors that are different, in parts, in Russian and foreign companies. Supplementary analysis also suggests that the positive connection between talent management efforts and a company's performance can be found.},

abstract = {Firms currently face numerous challenges when they operate abroad. To overcome these challenges many researchers define a set of vital factors that influence companies' successful operations in international markets. Among others, an important factor is the competencies of the top management team (TMT), which significantly influence an organisation's results. Currently, there is a lack of studies either observing the role of TMTs' competencies when a company decides to operate internationally or proving that a top manager's competencies are related to a firm's performance. To fill that gap, this paper explores how a TMT's competencies are associated with the realisation of a firm's international operations. The findings indicate that there is a strong correlation between top management competencies and the successful realisation of a firm's operations in international markets. Moreover, the evidence suggests that the most significant competencies for this are superior cognitive and analytical capabilities, ability to create and to use foreign contacts, project aptitude, and ability to create multicultural interaction. The research is based on the evidence of Russian companies operating in foreign markets.},

Our method, based on convex duality, only requires Hamiltonian functions to have C1,1 regularity while classical methods require additional regularity and cannot be applied to all cases found in practice.},

abstract = {Despite the growing public concern in recent years about the place of women in business, gender diversity in corporate governance has made little progress. As a consequence, the issue has captured the worldwide attention of policymakers. Several countries are currently adopting or considering the adoption of laws or regulations to promote gender diversity on corporate boards. The purpose of this paper is to compare the effectiveness of using legislative or regulatory means to increase female representation instead of allowing firms to voluntarily fix their own non?legally binding targets. We find that the relation between gender diversity and performance is positive in countries using the voluntary approach while it is negative in countries using the regulatory approach. We conclude that public policy aimed at increasing the number of women on corporate boards should be introduced gradually and voluntarily rather than quickly and coercively to avoid sub?optimal board composition.},

abstract = {The purpose of this paper is to examine the effect of gender diversity on the boardroom and in top management positions on earnings management by French-listed firms. Based on a sample of 170 firms over 4 years, we find that the proportion of women on the board standing as a director or a chair  reduces  earnings  management.  This  finding  suggests  that  women  are  effective  on  their monitoring role  and are  then considered as a crucial corporate  governance device. We  also find that  the  relationship  between  the  presence  of  at  least  three  women  on  the  board  and  earnings management  is  negative  suggesting  that  by  increasing  thenumber  of  women  on  board  through regulation  and  legislation,  French  firms  are  likely  to  enhance  the  effectiveness  of  the  board  to better detect earnings management. However, women standing in CEO and CFO positions do not affect earnings management practices. These findings suggest that efforts made by political bodies to  promote  equality  between  men  and  women  on  boards  are  beneficial  for  French-listed companies by limiting earnings management practices. However, regulating or imposing a quota of women on boards can create a temporal shortage of qualified women available to take up such positions.},

Building on the detailed analysis of emails exchanges from within Goldman Sachs, I utilize the Lacanian concept of ?ideological fantasy' to discuss how the traders' narratives bear witness to a certain logic of fantasy that appears to fuel corrupt activities. I also examine the cover-up tactics which were adopted to camouflage the corrupt operations and make them appear licit. Corrupt performances and their cover-up are theorized as forms of self-transgressive jouissance, a simultaneously pleasurable and self- destructive practice that is needed to sustain and protect the impossible norms of the corporation.},

Mathematically, the problem is new and related to both option pricing (Asian and Bermudan options) and optimal execution. We provide a model, along with associated numerical methods, to determine the optimal stopping time and the optimal buying strategy of the bank.},

abstract = {Statement of problem. Computer-aided design/computer-aided manufacturing (CAD/CAM) machining influences the surface roughness of dental restorations and tool wear. Roughness must be suitable to meet clinical requirements, and the tool must last as long as possible. Purpose. The purpose of this pilot study was to investigate the influence of the CAD/CAM toolmaterial couple on tool wear and surface roughness after milling. Material and methods. Three tools (Lyra conical tool Ø1 mm; GACD SASU, Lyra conical tool Ø1.05 mm; GACD SASU, and Cerec cylinder pointed tool 12S; Sirona Dental Systems GmbH) and 3 CAD/CAM materials (Lava Ultimate; 3M ESPE, Mark II; VITA Zahnfabrik H. Rauter GmbH, and Enamic; VITA Zahnfabrik H. Rauter GmbH) were tested. The tool wear of 6 tool-material couples at a feed rate of 2 m/min was analyzed before and after 8 minutes of flank and climb milling with optical and scanning electron microscopy (SEM) observations and tool weighing. The surface roughness after milling was observed for 9 tool-material couples for flank and climb milling. Feed rates of 1, 2, 3, and 4.8 m/min were used for each couple. Ra, Rt, Rz, Sa, Sq, and Sz roughness criteria were measured. A paired comparison of tool-material couples was conducted with the Kruskal-Wallis test. Results. The Mark II material led to more severe tool wear. Milling of Lava Ultimate resulted in chip deposits on the tool grit. The Cerec cylinder pointed tool 12S was less worn for each material tested. The Cerec cylinder pointed tool 12S and the Lyra conical tool Ø1.05 mm provided similar roughness measurements for the 3 materials tested. The Lyra conical tool Ø1.05 mm tool provided better roughness than the Lyra conical tool Ø1 mm tool for the Enamic material. Conclusion. Tool lifetime calculated by volume of milled material removed should be the measure

provided by CAD/CAM manufacturers instead of a number of blocks. This tool lifetime should be

provided for the milling conditions associated with the material milled. Material hardness and tool grit are key factors for achieving a given roughness.},

We propose a stochastic volatility model that recovers not only the typically observed implied volatility smiles and skews for short dated vanilla foreign exchange options but allows one also to price payoffs in foreign currencies, lower than possible under classical risk neutral pricing, in particular, for long dated derivatives. The main reason for this important feature is the strict supermartingale property of benchmarked savings accounts under the real world probability measure, which the calibrated parameters identify under the proposed model. Using a real dataset on vanilla option quotes, we calibrate our model on a triangle of currencies and find that the risk neutral approach fails for the calibrated model, while the benchmark approach still works.},

However, there is no clear corre- lation between this grade and patient functional outcome scores (Sanghi et al. 2011; Zifchock et al. 2011, Alkan et al. 2013). This leads to the need of a quantitative and precise measure to represent the knee function. In the recent years, to evaluate healthy and OA knee function, the trend was to track skin markers displacements, known to be affected by soft tissue artefacts (Leardini et al., 2005). On the other hand, with imagery-based methods, 3D model acquired either from CT scan or Magnetic resonance imaging are matched on 2D fluoroscopic images (kinematics) or several radiographs (pseudo-kinematics) (Moro-Oka et al., 2006). With objects of known geometry in the radiographic scene (bone-embedded tantalum beads or prostheses), this matching allows attaining kinematic measurement accuracy <1 and <1mm. Without tantalum beads or prostheses, the process lacks reliability and accuracy. Thus, our goal is to present an intrinsic computation method - without any object added in the scene - and to validate its reliability on patients' images as well as its accuracy on simulated radiographs in a pseudo- kinematic context.},

The fitness of moderately interdependent enterprises is greater than enterprises which are completely dependent. In order to gain an optimal level of innovation fitness, an enterprise can make appropriate adjustments, depending on the interdependence of its service capabilities. The innovation evolutionary path of synergetic services in e-commerce is proportionately in line with an S-curve. The system can forecast the macro-level evolution of a synergic service under real scenarios, and support competition-oriented enterprises' decision-making.
