The Importance of Behavioral Factors: How Do Overconfidence Affect Entrepreneurial Opportunity Evaluation?

Even though the entrepreneurship literature places much emphasis on opportunity recognition, little is known about how entrepreneurs actually evaluate opportunities. This study uses a cognitive approach to examine opportunity evaluation, as the perception of opportunity is essentially a cognitive phenomenon. We present a model that consists of four independent variables (overconfidence, risk perception, creativity, Relational networks and environmental factors, experience, education and opportunity identification), two control variables (demographics and age), and the dependent variable (opportunity evaluation). We find that overconfidence and risk perception are related to how entrepreneurs evaluate opportunities. Our results also indicate that entrepreneurial individual factors affect opportunity evaluation.

Retaining efficiency in an embedded system while introducing Lua as a means to improve maintainability: an actor model approach

Embedded touch display systems with limited resources still require responsive user interfaces, which puts high demands on the efficiency of the software. Embedded systems are expensive to maintain due to the low-level programming languages used for efficiency. By integrating the Lua scripting language as a complement to C, and using the message passing semantics of the actor model, maintainability and modularity can be increased while retaining efficiency. With this approach it is possible to develop efficient embedded systems with high maintainability responsive enough to be used in touch screen systems.
Numerical Model of Sediment Pulses and Sediment-Supply Disturbances in Mountain Rivers

Sediment pulses in rivers can result from many mechanisms including landslides entering from side slopes and debris flows entering from tributaries. Artificial sediment pulses can be caused by the removal of a dam. This paper presents a numerical model for the simulation of gravel bedload transport and sediment pulse evolution in mountain rivers. A combination of the backwater and quasi-normal flow formulations is used to calculate flow parameters. Gravel bedload transport is calculated with the surface-based bedload equation of Parker in 1990. The Exner equation of sediment continuity is used to express the mass balance at different grain size groups and lithologies, as well as the abrasion of gravel. The river is assumed to have no geological controls such as bedrock outcrops and immobile boulder pavements. The results of nine numerical experiments designed to study various key parameters relevant to the evolution of sediment pulses are reported here. Results of the numerical runs indicate that the evol.
Heterogeneous Fixed Export Costs and the Division of Labor

We theoretically investigates that how firms decide to exports and the extent of the division of labor under heterogeneous fixed export costs. In the equilibrium, exporters and non-exporters coexists and all exporters behave as borderline firms. Exporters promote the division of labor more strongly than non-exporters. A decrease in trade costs raises the cut off export fixed costs. It expands firm size and promotes the division of labor of exporters, while it shrinks firm size and make non-exporters refrain from the division of labor. These links between the cut off fixed export costs and the division of labor of exporters and non-exporters bring a new insight for the research line of trade and heterogeneous fixed export costs
ideally Ca ( Al 0 . 5 Ta 0 . 5 ) ( SiO 4 ) O , a new mineral of the titanite group from the Pi ł awa Górna pegmatite , the Góry Sowie Block , southwestern Poland

Żabin ́skiite, ideally Ca(Al0.5Ta0.5)(SiO4)O, was found in a Variscan granitic pegmatite at Piława Górna, Lower Silesia, SW Poland. The mineral occurs along with (Al,Ta,Nb)and (Al,F)-bearing titanites, a pyrochlore-supergroup mineral and a K-mica in compositionally inhomogeneous aggregates, ∼120 μm × 70 μm in size, in a fractured crystal of zircon intergrown with polycrase-(Y) and euxenite-(Y). Żabin ́skiite is transparent, brittle, brownish, with a white streak, vitreous lustre and aMohs hardness of∼5. The calculated density for the refined crystal is equal to 3.897 g cm, but depends strongly on composition. The mineral is non-pleochroic, biaxial (–), with mean refractive indices≥1.89. The (Al,Ta,Nb)-richest żabin ́skiite crystal, (Ca0.980Na0.015)Σ=0.995(Al0.340Fe 3þ 0:029Ti0.298V0.001Zr0.001Sn0.005Ta0.251Nb0.081)Σ=1.005[(Si0.988Al0.012)O4.946 F0.047(OH)0.007)Σ=5.000]; 60.7 mol. % Ca[Al0.5(Ta,Nb)0.5](SiO4)O; is close in composition to previously described synthetic material. Żabin ́skiite is triclinic (space group symmetry A 1) and has unit-cell parameters a = 7.031(2) Å, b = 8.692(2) Å, c = 6.561(2) Å, α = 89.712(11)°, β = 113.830(13)°, γ = 90.352(12)° and V = 366.77 (11) Å. It is isostructural with triclinic titanite and bond-topologically identical with titanite and other minerals of the titanite group. Żabin ́skiite crystallized along with (Al,Ta,Nb)-bearing titanites at increasing Ti and Nb, and decreasing Ta activities, almost coevally with polycrase-(Y) and euxenite-(Y) from Ca-contaminated fluxed melts or early hydrothermal fluids.
CEO Characteristics and Corporate Financing in Thailand

Previous financial crises have cast some doubt about the risk-taking behaviors of top executives. This study investigates the impact of CEO characteristics on corporate financing behaviors after the 1997 Asian financial crisis. Sample firms are non-financial listed firms on the Stock Exchange of Thailand between 2001 and 2005. We use the Ordinary Least Square (OLS) method on pooled cross-section and time-series data controlling for year and industry effects. CEO characteristics are classified into three groups—biography, network and incentives—based on the upper echelons, resource dependence and agency theories, respectively. According to the upper echelons theory, the education of CEOs has an impact on strategic choices. The result shows that CEOs with postgraduate education choose a higher level of financial leverage. Based on the resource dependence theory, networks ease difficulties to access to external resources. We find that politically connected CEOs can finance higher debt, compared to non-connected CEOs. Our findings also support the agency theory. We find that family CEOs use more debt possibly to maintain their voting power. Overall, our research shows that CEO characteristics affect financing decisions. From lenders’ point of views, some attributes of CEOs may reflect better repayment abilities of firms, thus encouraging lenders to provide higher loans. Our study also suggests that to thoroughly investigate the significance of CEOs in shaping corporate strategies, wide aspects of CEO attributes should be considered.
A Computational Interactive Approach to Multi-agent Motion Planning

It is well known that mathematical solutions for multi-agent planning problems are very difficult to obtain due to the complexity of mutual interactions among multi-agents. Most of the past research results are thus based on the probabilistic completeness. However, the practicality and effectiveness of the solution from the probabilistic completeness is significantly reduced by heavy computational burden. In this paper, we propose a practically applicable solution technique for multi-agent planning problems, which assures a reasonable computation time and a real world application for more than 3 multi-agents, for the case of general shaped paths in agent movement. First, to reduce the computation time, an extended collision map is developed and utilized for detecting potential collisions and obtaining collision-free solutions for multi-agents. Second, a priority for multi-agents is considered for successive and interactive modifications of the agent movements with lower priority. Various solutions using speed reduction and time delay of the relevant agents are investigated and compared in terms of the computation time. A practical implementation is finally provided for three different types of agents to emphasize the effectiveness of the proposed interactive approach to multi-agent planning problems.
Contrasting biogeochemical cycles of cobalt in the surface western Atlantic Ocean

Dissolved cobalt (DCo; <0.2 µm; 14 to 93 pM) and the apparent particulate cobalt (PCo; >0.2 µm; <1 to 15 pM) were determined in the upper water column (<1000 m) of the western Atlantic Ocean along the GEOTRACES‐A02 section (64°N to 50°S). The lowest DCo concentrations, typical of a nutrient‐type distribution were observed in surface waters of the subtropical domains. Strong linear relationships between DCo and phosphate (P) as well as meridional gradients of decreasing DCo from high latitudes were characterized and both linked to the Co biological requirement. External sources such as the Amazon and the atmospheric deposition were found to contribute significantly (>10%) to the DCo stock of the mixed layer in the equatorial and north subtropical domains. Biotic and abiotic processes as well as the physical terms involved in the biogeochemical cycle of Co were defined and estimated. This allowed establishing the first global budget of DCo for the upper 100 m in the western Atlantic. The biological DCo uptake flux was the dominant sink along the section, as reflected by the overall nutrient‐type behavior of DCo. The regeneration varied widely within the different biogeochemical domains, accounting for 10% of the DCo‐uptake rate in the subarctic gyre and for up to 85% in southern subtropical domain. These findings demonstrated that the regeneration is likely the prevailing source of DCo in the surface waters of the western Atlantic, except in the subpolar domains where physically driven sources can sustain the DCo biological requirement.
Patterns of physical activity and dietary habit in relation to weight status in adolescent girls

Healthy eating and physical activity habits formed during childhood can persist into adulthood and prevent or delay premature onset of a number of chronic diseases. The aim of this study was patterns of physical activity and dietary habit in relation to weight status in adolescent girls. In a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 Semnan secondary schools. Weigh and height were measured and Body Mass Index (BMI) was calculated. In adolescents, anthropometric indices were defined based on the CDC 2000 cut-off points for age and gender-specific BMI. Data of energy and nutrient intake was collected with the 24-hour dietary recall and food record questionnaires. The food frequency questionnaire was used to evaluate daily food consumption. Physical activity was determined using Baecke questionnaire. Data analyzed indicated that daily fat intake (p=0.003, r=+0.18), energy percent of fat (p=0.04, r=+0.01) and fast food frequency (p=0.026, r=+0.139) had significant relationship with BMI percentile. There was a significant relationship between snack frequency and weight status in high school adolescent girls (p=0.023). Data analyzed indicated that physical activity had significant relationship with weight status in adolescent girls (p= 0.0001). The findings suggest that make physical activity enjoyable and improvement food habit among adolescent girls are necessary to induct.
An Efficient Privacy Preserving Technique Using Decoy Passwords

As per the rapid growth and essentiality in the field of information security, the data authentication and data access control are the major concerns. Now-a-days many users prefer to share their data through websites are bound to have many security related issues such as leakage of password file. To provide security against cyber threats in the above dimensions We proposed a decoy based passwords system. Honeywords are the Decoy (fake) passwords. If an attacker steals the password file, it will include original password and honeywords and password cracking becomes tougher. Further we improved the flatness of honeyword generation system using masked password generation algorithm based on randomized technique. So, for an adversary it will become harder to distinguish between original password and a honeyword. The administrator gets notification if any illegal login done apart from the genuine user. In this system the main advantage is that sensitive data can’t be viewed by the unauthorized user. For this Identity Based Encryption (IBE) has been implemented. By this, only the user with genuine credentials allowed to view the original data.
IMPRESSION MANAGEMENT IN CHAIRMEN’S LETTERS: AN EMPIRICAL STUDY OF BANKS’ ANNUAL REPORTS IN MENA REGION

The study aims to investigate the extent of existence of strategies of impression management (IM) in the narrative section of 200 annual reports of a sample of 50 banks in five different countries of Middle East and North Africa (MENA) region (Egypt, Jordan, Lebanon, Saudi Arabia, and United Arab of Emirates) for 2011-2014. Seven variables were employed to identify the existence of IM strategies in the chairmen’s letters of the bank’s annual reports. By employing descriptive statistics, frequency distribution and proportion test, it was found that four out of the seven strategies have existed in the chairmen’s letters. These strategies are reading ease manipulation, visual and structural manipulation, performance comparisons, and performance attribution. It is interesting to note that the annual reports narrative of major banks in MENA region were very difficult to read. This result may perhaps encourage more consideration to the obstacles of effective communication that is the basic mean of facilitating rational resource decision making. Moreover, the results demonstrated that management of banks in MENA region choose benchmarks that portray current bank performance in the best possible light; further they highlight good news rather than bad news and placing these good news in the most emphasized sections of the chairmen’s letters; also they prefer to blame the environment for bad news, but take the credit themselves for good news. Therefore, the study recommends auditing regulators to issue a new standard in which auditors are required to confirm reliability of the information in the accounting narratives of banks annual reports.
A LOCATION-INVENTORY MODEL INCLUDING DELIVERY DELAY COST AND CAPACITY CONSTRAINTS IN A STOCHASTIC DISTRIBUTION NETWORK

In this paper, we present a distribution network design problem in a supply chain system that minimises the total cost of location, inventory, and delivery delay. Customers’ demands are random, and multiple capacity levels are available for the distribution centers. The problem is first formulated as a mixed integer convex programming model to optimally solve medium-sized instances, and then a heuristic is developed for solving large-sized instances. OPSOMMING In hierdie artikel word ‘n distribusienetwerkprobleem in ‘n voorsieningsketting voorgehou waar die totale koste van die ligging, voorraad en afleweringsvertragings geminimiseer word.

Die problem word eers geformuleer as ‘n gemengde-heeltal-konvekse model sodat mediumgrootte gevalle geoptimiseer kan word, waarna ‘n heuristieke benadering ontwikkel word vir die oplos van grootskaalse aktiwiteite.
Identification of the dissipated energy by friction in dynamic multibody systems

This paper is devoted to the modeling of finite deformations of elastic bodies under contact/impact conditions. In this kind of applications, it is well known that the total energy will be reduced versus time because of frictional effects. However, how to identify the dissipated energy in a quantitative way remains an open question. The aim of this work is to propose a numerical solution to this question. The proposed Bi-First algorithm combines the bi-potential method for contact modeling in dynamic cases and the first order algorithm for integration of the equation of motion. Numerical examples involve the impact of an elastic plate onto a rigid surface and the impact between two hyperelastic blocks and a rigid wall. The dissipated energy versus time will be plotted and the influence of friction coefficient on the dissipated energy will be discussed.
Immune Response to Hepatitis B Vaccine among Dental Students

Hepatitis B infection is a major public health problem worldwide. Dental students who are frequently in contact with body fluids like blood and saliva are still at high risk for HBV exposure. The aim of this study was to evaluate the effectiveness of HBV vaccine and personal factors associated with serologic evidence of the immune response. Methods: A descriptive-cross sectional study was carried out using data from Hamadan dental school students that received just three doses of HBV vaccine. The serum sample of 86 dental clinical students were examined in order to determine hepatitis B surface antigen and the level of anti-HBs using IEMA method. Logistic regression models were used to assess the relationship of vaccine response to the variables Sex, age weight, smoking status and the time lasting from the third dose of vaccine injection. Results: Ninety-three percent had positive anti-HBs response and 7% were non-responders. No one showed HBsAg. Vaccine response was most strongly associated with age, smoking status, sex and weight. The time lasting from the third dose was unrelated to vaccine response. Conclusion: Clinical dental students had desirable immune response to the HBV vaccine nevertheless recommended num- ber of doses, standard protocol and early vaccination are critical to adequate protection against hepatitis infection among all health care workers, in particular dental students and dentists who are often exposed to blood and other body fluids.
A Comparison of Conferencing Strategies Used in Two Different Supervisory Dyads and the Effects on Teachers' Classroom Management Behaviour.

This paper presents, in five sections, a comparison of conferencing strategies used in two different supervisory dyads and the effects of the strategies on teachers' classroom management behavior. The first section is an overview of a larger study that sought to determine if the improvement of management practices cf supervisees is associated with conferencing (principal-led intervention) or with research-verified knowledge about classroom management taught by supervisors trained in conferencing techniques (a "common language" approach). The second and third sections present case studies of each dyad. The first dyad is composed of a high conceptual level (CL) principal interacting with a low CL teacher; the second, of a low CL principal interacting with a low CL teacher. The fourth section compares the two different dyads in terms of the conferencing strategies used by the high and low CL principals, and in terms of the associated effects that were evident in the teacher's classroom management practices. The final section offers some concluding observations about the nature of the dyadic interactions. Findings revealed that a teacher's conceptual level and the role that the teacher's responses play in the dynamic of conference interaction, the principal's knowledge of pertinent content (in the case of this study. classroom management), the principal's ability (cr lack thereof) to observe classroom events accurately, the principal's ability to transform a facilitating approach into an enabling one, and certain aspects of organizational life that act as constraints on both principal and teacher enhance or inhibit the teacher's classroom management processes.

Treatment of domestic greywater by geotextile filter and intermittent sand filtration bioreactor

Intermittent sand filtration (ISF) is an efficient system for treatment of greywater; however, the high quality of effluent and the simple set-up contrast with the high failure rate due to clogging of surface layers. The efficacy of several polypropylene non-woven geotextiles (apparent opening size from 0.10 to 0.18 mm) used as primary treatment filters to remove suspended particles from domestic greywater and the effects of this pretreatment in the performance of fine and small media size (0.3 and 0.6 mm) ISFs was examined. Results showed geotextile achieved suspended solids (SS) removal rates from 25 to 85% and chemical oxygen demand (COD) from 3 to 30%; although the portion larger than 75 μm was removed at higher rates (55–90%), particles smaller than the nominal pore size of the filter were also captured. Geotextile used as pretreatment resulted in improvement of lifetime of the ISFs over an experimental run of 60 days. The vertical profile of volatile organic matter in the ISFs was evaluated at the end of the experiment and it showed a clear reduction in the accumulation of organic material on the top layer of the ISFs, effectively avoiding its early failure by accumulation of solids.
Hybrid Learning: An Effective Resource in University Education?

The organisation of university education in Europe is undergoing profound changes as a consequence of the establishment of the European Higher Education Area (EHEA). This transformation entails methodological changes that are focused on student work. The student is now considered to be an autonomous individual who is able to choose a path of study and capable of self-regulation. These objectives are believed to be achievable with hybrid learning models. The economic cost of including these methods makes it necessary to demonstrate whether the investment can be profitable in terms of improved academic results and increased acceptability among students. We analyse whether the use of two tools by students (assessments and forums) influences their grades and whether there are correlations between performance and the evaluation of the tool by students and between the evaluation and the degree of use. The sample consists of 176 students. We follow an ex post facto methodological design, with descriptive and correlational techniques. We found significant differences in the grades received according to the degree of use of the tools studied. Additionally, we found a correlation between grades and student evaluation.
