Risk preferences in China : results from experimental economics.

The propensity to take risks is a fundamental trait that determines the nature of decision making. For example, risk taking is regarded as an important driver of entrepreneurial and innovative behavior in an economy. In this paper, we survey the empirical evidence on individual risk-taking behavior in China. We focus on those studies that elicit preferences for risk taking involving real monetary stakes under controlled conditions, using the methods of Experimental Economics. The studies that we summarize compare Chinese subjects to those in other countries. While nonincentivized surveys find that Chinese subjects are more willing to take risks than Germans and Americans are, the existing experimental studies suggest that this relationship is less clear cut.
Exploring Multimedia Web Conferencing

Internet changed the perspective on meetings and also on decision making processes. Virtualization of meetings has become a common way for collaboration among employees, customers, partners, trainees and trainers, etc. Web conferencing allows the collaboration between teams' members to achieve common goals. Without the need of travelling and meeting organization, the web conferencing applications permit the participation of people from different location. Web conferencing applications are multimedia systems that allow various remote collaborations with multiple types of resources. The paper presents an exploratory study on multimedia web conferencing systems, its advantages and disadvantages and also a use case, meant to highlight several of this technology benefits and problems.
Experimental Tests for Cross Wedge Rolling of Forgings Made from Non-Ferrous Metal Alloys / Próby Doświadczalne Walcowania Poprzeczno-Klinowego Odkuwek Ze Stopów Metali Nieżelaznych

Reported in this paper are the experimental test results for hot cross wedge rolling of elementary shaft forgings made from light metal alloys which are widely used in aviation industry, such as aluminum alloys 6101A and 2618A, titanium alloy Ti6Al4V as well as magnesium alloys AZ31 (Mg 3Al-1Zn-Mn), AZ61 (Mg 6Al-1Zn-Mn) and Mg4AlZnMn. The research works were conducted by means of a flat-wedge rolling mill LUW-2, with typical wedge tools used. The experiment tests involved the analysis of force parameters, geometrical parameters, and process stability. The conducted experimental tests prove the feasibility of forming axially symmetric parts made from light metal alloys in CWR (cross wedge rolling) processes. Limitations upon the application of CWR technologies to forming such alloys are also described.
Isolation and characterization of a strain of African from a local cassava in the Re

Gemini particles were purified from infected local cassava by a method which was developed and the virus was characterized. Virus particles measured ca. 36 x 23 nm. Purified virions or their nucleic acid transmitted to Nicotiana benthamiana, N. debneyi, N. clevelandii, and Datura stramonium plants showed difference in symptom expression compared to another strain of the virus received from the German Collection of Microorganisms in Braunschweig. Viral capsid protein was resolved by SDS-PAGE. Its estimated molecular-weight was 30 kD. A single nucleic acid of estimated molecular-weight of 0.7 x 106 D was isolated from virus particles and resolved by agarose gel electrophoresis. Thin-section electron microscopy of infected and healthy leaf of cassava and of N. benthamiana plants revealed no cytopathic effects common to whitefly-transmitted geminiviruses. Ultrastructural features like hypertrophy and segregation of nuclear components were observed in ACMV-infected leaves of cassava and of N. benthamiana plants, but they could also be detected rarely in healthy materials. With antisera prepared to ACMV, the virus content in different parts of casava plants were determined by ELISA. The virus isolated from the local cassava and the strain received from Braunschweig were identified with the monoclonal antibody SCR 23 as strains of the geminivirus group A (strains of West-Africa and West-Kenya).
Ethical Issues at Work: A Comparative Study between UK and Indian Managers

The objective of the paper is to study ethical stances taken by Indian managers on issues related to redundancy and to compare them with those of UK. The responses of Indian and UK managers to ethical issues are assessed using a research instrument called ‘Redundancy’ against eight ethical stances. The findings suggest that Indian managers in comparison to UK managers take ethical puzzle stance less frequently when responding to ethical issues at work. The UK managers tend to look at the issue with a systematic approach collecting enough data for identifying the most suitable answer whereas the Indian managers experience a tension between their ethical beliefs and those they are required to apply at work. Nevertheless, Indian managers show important ethical considerations from family and other social connections.
Empirical Analysis of Money Demand Stability in Nigeria

The main focus of this study is to identify the variables influencing the demand for money in Nigeria; and to ascertain the stability of money demand in Nigeria. Related theories and empirical researches in this area were reviewed in order to ensure the relevance of variables under study and possible expectation of their relationship with money - demand in Nigeria. Four explanatory variables were specified for this study based on theoretical underpinning. Stationarity test were conducted and all variables were stationary at first difference, with two cointegrating equations after using the Johansen Cointegration test. The error correction model (ECM) was rightly signed and revealed a recovery rate of 18 percent. It was also recommended among others that the monetary policy strategy of the CBN should be structured to deal with the growing challenges posed by financial innovations. The stability test revealed that M2 money demand in Nigeria is stable using both CUSUM and CUSUMSQ at 5 percent critical lines. Keywords: Money-Demand, Non-Bank Financial Institutions, Speculative demand for money, Liquidity, cointegration.
Human Resource Strategies as a Mediator between Leadership and Organizational Performance

Leadership style is a kind of method that aims to realize organizational targets and affect all organizational activities. This quantitative study focused on various business domains in Saudi Arabia to examine how leadership styles are related to human resource strategies and organizational performance. The study adopted the self-administered survey methodology technique using a pre-validated pre-piloted questionnaire. Data were analyzed using Structural Equation Modelling. A total of 270 questionnaires were distributed with a response rate 92.9% based on a convenience method. Our survey found a direct positive relationship between leadership style and organizational performance and an indirect relationship between leadership style and human resource strategy as a mediator, while human resource strategies contribute positively and significantly to organizational performance. The findings are relevant for operating human resource management strategies and for developing a style of leadership. An enterprise can use this information to promote recognition and devotion among its employees based on a range of strategies, and then creates overall performance of the organization. Also, it is possible to use different leadership styles for different strategies. Consequently, this study has both theoretical and practical reference value.
DERIVATION VIABILITY OF RESISTANT STARCH FROM SOME COMMON FRUIT SEEDS IN VIET NAM FOR INDUSTRIAL PRODUCTION

The study aimed to compare the ability of extracting resistant starch (RS) from three common fruit seeds in Vietnam, namely avocado, jackfruit and mango seed. Avocado (Persea Americana) seeds, jackfruit (Artocarpus heterophyllus) seeds and mango (Mangifera indica L.) seeds were collected from local markets in Ho Chi Minh City, processed and extracted of starch. Three starch granules were then analyzed for RS content according to AOAC Standard 2002.02. Simultaneously, the effects of temperature (100, 120 o C), time (10, 15, 20 minutes) and heating methods (drying, steaming) on RS content in three starch granules were also investigated to evaluate heat-stability of these RS. The content of RS (% dry matter) in avocado seeds, jackfruit seeds and mango seeds was 23.59 %, 27.06 % and 32.12 %, respectively. Heat-stability of avocado seed RS was the least, mean while heat-stability of mango seed RS and jackfruit seed RS were higher and similar. The RS content slightly decreases after 10 and 15 minutes of heating, but significantly decreases after 20 minutes of heating. Drying reduces the RS content of the materials more than steaming. The results suggest that jackfruit seed seems to be better than avocado and mango seeds in the content and heat-stability of RS. Further studies should be conducted to choose a potential seed type for building an RS extracting processing in industrial production.
Climatic effects of land cover change at different carbon dioxide levels

Land cover change (LCC) simulations were performed at 3 different carbon dioxide lev- els (280, 355 and 430 ppmv) using the standard version of the NCAR CCM3 at T42 resolution coupled with the Biosphere-Atmosphere Transfer Scheme (BATS) and a mixed-layer ocean model. We follow the evolution of the initial temperature perturbation within the horizontal and vertical structure of the atmosphere and then examine the 15 yr average of near-surface air temperature and meridional stream function differences between current and natural land cover at the 3 different CO2 levels. Results show that LCC caused temperature perturbations which initially affected only those regions where the land cover was modified. After a short period, however, the effects of LCC propagated to remote regions. While the remote effects of LCC were generally different at each CO2 level, 4 com- mon remote regions of sensitivity were identified in these simulations (North Pacific, North America, northeast Asia and the Indian Ocean). The main factor in explaining the differing remote responses was the change in the zonally averaged background circulation resulting from circulation changes caused by LCC, CO2 level, and the interaction between these 2 forcings. The 15 yr average seasonal results indicate that LCC may have impacts on surface air temperature which vary in sign between seasons, depending on the character of the initial land cover perturbation as well as local meteoro- logical conditions. We find no evidence that the impacts of LCC decrease with increasing CO2, rather we show that LCC does appear to affect regional climate at a statistically significant level.
A Hybrid Approach to Detect Suspicious URLs

Social network services are increasing trend now days. Communicating between people forms a social network. Personal information is usually collected through Social network services in targeted attacks and craft attacks based on a specific user profile. Online payment systems can be used to create a fake payment portal by using a similar gateway URL (Online fraud). Because users are curious and unknown, they generally click on suspicious URLs without verification. A feature set is presented that merged the features of traditional heuristics and lexical features of URLs. A suspicious URL identification system for use in all over web environments is proposed based on K-means clustering algorithm and Bayesian classification.
8th International IFAC Symposium on Dynamics and Control of Process Systems MEASURES OF TOPOLOGICAL RELEVANCE FOR SOFT SENSING PRODUCT PROPERTIES

We address the problem of real-time monitoring of products’ properties from spectroscopic measurements. Spectra are used as inputs for soft-sensors that estimate outputs difficult to measure on-line. To overcome the issues associated to calibrating such models from high-dimensional inputs, we propose to select the relevant inputs emerging from the topological structure of the data. The approach is independent on the estimation model to be embedded in the sensor. Being based on the original spectral features, the models retain the interpretability of the underlying system. The application of the method is illustrated on two cases from refining and pharmaceutical industry. Copyright c © 2007 IFAC
A Multilevel Evolutionary Algorithm Applied to the Maximum Satisfiability Problems

The maximum satisfiability problem that is known to be nondeterministic polynomial (NP) complete plays a central role problem in many applications in the fields of very large-scale integration (VLSI) computer-aided design, computing theory, artificial intelligence, and defense. Given a set of m clauses and n Boolean variables, the maximum satisfiability problem refers to the task of finding an assignment of values to the variables that maximizes the number of satisfied clauses (or minimizes the number of unsatisfied clauses) In this chapter, a multilevel evolutionary algorithm is proposed for the maximum satisfiability problem. The multilevel process works by grouping the variables defining the problem to form clusters, uses the clusters to define a new problem, and is repeated until the problem size falls below some threshold. The coarsest problem is then given an initial assignment of values to variables and the assignment is successively refined on all the problems starting with the coarsest and ending with the original.
Model Reduction and Control of a Compressible Channel Flow with Combustion

Abstract A model reduction for a compressible flow with combustion is performed using the POD-Galerkin procedure. The model parameters are determined by an optimization. The obtained reduced-order model is incorporated in a model predictive controller and results are shown from a closed-loop CFD-simulation. The controller influences the fuel mass-flow boundary condition to control the temperature at a certain point within the computational domain.
Whose "Fault" Is This? Untangling Domain Concepts in Ontology Design Patterns

Certain ontology domain concepts are difficult to model due to the complexity of their definition, the number of roles that they fulfill in the ontology or the different types of relationships they participate in. To assist ontologists in overcoming some of these challenges, a comparative analysis of two Ontology Design Patterns (ODPs) has been carried out. As a result, terminology is introduced to describe the role and certain reusability characteristics of domain concepts in these ODPs. These findings provide a series of implications that make explicit certain modeling decisions that previously were implicit in the ontology modeling field. Our contribution is illustrated with a concrete example of a real world use case scenario that will benefit from the outcome of this study.
Real-time motorized electrical hospital bed control with eye-gaze tracking

Patients with motor neuron disease and most terminal patients cannot use their hands or arms, and so they need another person for their all needs. However, the mental functions and memories of such patients are generally sound, and they can control their eyes. Using an eye-gaze tracking technique, we have realized a real-time system for such patients. The system controls a motorized electrical hospital bed (EHB) by eye gaze with 4 degrees of freedom, using a low-cost webcam. Contactless systems that require calibration cannot be used for EHB control. The system developed in this work does not require any calibration process and it is contactless. These properties are the most innovative part of the proposed approach. To begin, the system detects the eye region and computes the iris centers. It then tracks the centers and moves a mouse pointer on a screen with the eye gaze. The specific movements of the mouse pointer are evaluated as position changing requests and the completed movements of the mouse pointer change the EHB position electrically. The communication between the computer and the EHB is provided by a relay control card driven by Arduino Mega. The system works under day/artificial lighting conditions successfully with or without eyeglasses. The system was tested with 30 volunteers on the EHB safely and was completed with 90% success (the exceptions being people with slanted eyes).
Resistance Training and Youth.

The use of resistance training for children has increased in popularity and interest. It appears that children are capable of voluntary strength gains. Exercise prescription in younger populations is critical and requires certain program variables to be altered from adult perspectives. Individualization is vital, as the rate of physiological maturation has an impact on the adaptations that occur. The major difference in programs for children is the use of lighter loads (i.e., > 6 RM loads). It appears that longer duration programs (i.e., 10-20 wks) are better for observing training adaptations. This may be due to the fact that it takes more exercise to stimulate adaptational mechanisms related to strength performance beyond that of normal growth rates. The risk of injury appears low during participation in a resistance training program, and this risk is minimized with proper supervision and instruction. Furthermore, with the incidence of injury in youth sports, participation in a resistance training program may provide a protective advantage in one's preparation for sports participation.
Hazard Implications of the 2016 Mw 5.0 Cushing, OK Earthquake from a Joint Analysis of Damage and InSAR Data

The Cushing Hub in Oklahoma, one of the largest oil storage facilities in the world, is federally designated as critical national infrastructure. In 2014, the formerly aseismic city of Cushing experienced a Mw 4.0 and 4.3 induced earthquake sequence due to wastewater injection. Since then, an M4+ earthquake sequence has occurred annually (October 2014, September 2015, November 2016). Thus far, damage to critical infrastructure has been minimal; however, a larger earthquake could pose significant risk to the Cushing Hub. In addition to inducing earthquakes, wastewater injection also threatens the Cushing Hub through gradual surface uplift. To characterize the impact of wastewater injection on critical infrastructure, we use Differential Interferometric Synthetic Aperture Radar (DInSAR), a satellite radar technique, to observe ground surface displacement in Cushing before and during the induced Mw 5.0 event. Here, we process interferograms of Single Look Complex (SLC) radar data from the European Space Agency (ESA) Sentinel-1A satellite. The preearthquake interferograms are used to create a time series of cumulative surface displacement, while the coseismic interferograms are used to invert for earthquake source characteristics. The time series of surface displacement reveals 4–5.5 cm of uplift across Cushing over 17 months. The coseismic interferogram inversion suggests that the 2016 Mw 5.0 earthquake is shallower than estimated from seismic inversions alone. This shallower source depth should be taken into account in future hazard assessments for regional infrastructure. In addition, monitoring of surface deformation near wastewater injection wells can be used to characterize the subsurface dynamics and implement measures to mitigate damage to critical installations.
Profitability in Asset Pricing Models for Chinese Equities 1996-2016

I follow Novy Marx (2011, 2013) to investigate and compare firms’ gross profit, operating leverage as predictors of returns for a cross-section of traded Chinese equities spanning from1996-2016. I use portfolio tests and Fama-MacBeth regressions, find that gross-profit-to-market-capitalization ratios significantly predict returns on sampled stocks. I also find that sorting portfolios by gross profitability and size outperforms in the Chinese market. Hence, I create a Market-Profitability-Size model that captures profitability and size premium among returns of sampled stocks. Based on Gibbons-Ross-Shanken test and economic value, I demonstrate that my enhanced model outperforms Fama-French multiple-factor model in isolating influences on equity returns.
Cutoff Values of the Body Fat Mass and Visceral Adiposity for the Prediction of Metabolic Syndrome in a sample of Colombian University Students

Background: Visceral obesity and high body fat percentages are related to metabolic syndrome (MetS) in all ethnic groups. Based on the International Diabetes Federation (IDF) definition of MetS, the aim of the study was to explore thresholds of body fat (BF%) and the visceral fat area (VFA) for the prediction of MetS among Colombian university students. Methods: A cross-sectional study was conducted on 886 volunteers (51.9% women, mean age= 21.4 years). Weight, height, serum lipids indices, blood pressure, fasting plasma glucose, and waist circumference were measured. BF% and VFA were calculated by bioelectrical impedance analysis (BIA). MetS was defined as including ≥ 3 of the metabolic abnormalities according to the IDF definition. Results: The overall prevalence of MetS was found to be 5.9%, higher in men compared to women. BF% and VFA was positively correlated to MetS components (all p < 0.001). The optimal cutoff values for BF% in predicting MetS were 31.9% (sensitivity and specificity of 78.6 and 76.7%) in women and 20.3% in men (sensitivity and specificity of 79.5 and 82.5%). ROC curve for participants showed that VFA ≥ 4.9 mm in women and 4.3 mm in men are an indicator to best predict MetS for prediction in university students from Colombia. Conclusion: Based on the IDF criteria, both indexes were able to predict MetS in our population.
An economic model of international wood supply, forest stock and forest area change

Abstract Wood supply, the link between roundwood removals and forest resources, is an important component of forest sector models. This paper develops a model of international wood supply within the structure of the spatial equilibrium Global Forest Products Model. The wood supply model determines, for each country, the annual forest harvest, the annual change of forest stock and the annual change of forest area. The results suggest that global forest area would decline by 477 million ha between 1999 and 2030, with the largest decline in Asia and Africa. However, global forest stock would increase by 25 billion m3, with the largest increase in Europe, and North and Central America. Higher global harvests and lower prices were predicted than those predicted in the past with exogenous timber supply assumptions.
