Managing Stakeholders of a Tourism Company

The paper describes the possibilities of using the method of stakeholder analysis based on the example of tourism companies. On the basis of the characterisation of particular stakeholder groups the hierarchy of importance was created which is a significant contribution to service company management. The analysis concerned all aspects of the functioning of a tourism company: microenvironment, macroenvironment and competitive environment. The picture obtained as a result of analysis forms the basis for further research into stakeholders and defining a complex strategies of managing relationships among them.
X-ray observations of cluster outskirts: current status and future prospects

Past and current X-ray mission allow us to observe only a fraction of the volume occupied by the ICM. After reviewing the state of the art of cluster outskirts observations we discuss some important constraints that should be met when designing an experiment to measure X-ray emission out to the virial radius. From what we can surmise, WFXT is already designed to meet most of the requirements and should have no major difficulty in accommodating the remaining few.
Different Communication Protocols for Wireless Sensor Networks: A Review

Recent development in the area of micro-sensor devices have accelerated the advances in the sensor networks field leading to many new protocols specifically designed for wireless sensors networks(WSNs). wireless sensors networks with hundreds to thousands of sensor nodes can gather information from an unattended location and transmit the gathered data to a particular users, depending on the applications. These sensor nodes have some constraints due to their limited energy, storage capacity and computing power. Data are routing from one node to other using different routing protocols. There . this paper gives brief idea about different protocols in wireless sensor networks (like LEACH, SEP, HRC etc.) also included comparison of these protocols.
Orthogonal Discriminant Diversity and Similarity Preserving Projection for Face Recognition

Feature extraction is a crucial step for face recognition. In this paper, based on supervised local structure and diversity projection (SLSDP), a new feature extraction method called orthogonal discriminant diversity and similarity preserving projection (ODDSPP) is proposed for face recognition. ODDSPP defines two parameterless weighted matrices by taking into account the class label information and local structure. Thus ODDSPP could utilize both the diversity and similarity information of the data simultaneously for dimensionality reduction. Moreover, the proposed algorithm is able to extract the orthogonal discriminant vectors in the feature space and does not suffer from the small sample size problem, which is desirable for many pattern analysis applications. Experimental results on the ORL and AR databases show the effectiveness of the proposed method.
A Psychological Perspective to the Rule of Law in Nigeria and Implications for Foreign Direct Investment

Democracy involves submission to the will of majority. It is a pact that keeps ‘countrymen’ in the single body politic and is between free men, not between rulers and the ruled. It is in this context that the rule of law becomes the norm. However, Nigerian laws are deliberately punctuated with loopholes so as to serve the interest of successive ruling elites. The social cognitive theory explains the path-ways through which leaders in government perpetrate their guided dictatorship in the name of democracy, as well as why the leadership elite may never surrender to popular democracy as anticipated by the social contract theory; hence corruption among these elites has made most citizens very poor. This scenario engenders distrust, alienation, a sense of deprivation and frustration among the citizens, and culminates in lack of group cohesion, unrest and insecurity as many citizens flout the laws to survive. Thus the investment atmosphere becomes adversely affected. Keywords: Psychology; Law; Democracy; FDI.
Robust Fuzzy H ∞ Output Feedback Control for a Class of Nonlinear Uncertain Systems with Mixed Time Delays

This paper studies the problem of delay-dependent robustH ∞ output feedback control for a class of uncertain fuzzy neutral systems with both discrete and distributed delays. The system is described by a state-space Takagi-Sugeno fuzzy model with distributed delays and norm-bounded parameter uncertainties. The purpose is to design a fuzzy dynamic output feedback controller which ensures the robust asymptotic stability of the closed-loop fuzzy neutral system and satisfies an H ∞ norm bound constraint for all admissible uncertainties. In terms of linearmatrix inequalities, sufficient conditions for the solvability of this problem are presented. Finally, a numerical example is included to demonstrate the effectiveness of the proposed method.
Customer Involvement into Open Innovation Processes: a Conceptual Model

The studies on open innovation as a phenomenon have been increasing dramatically in the few past decades. There are two basic approaches towards open innovation analysis from the firm perspective: 1) open innovation as a result of networking and collaboration of various types of business and non-business organizations, 2) open innovation as a result of firm’s partnership and collaboration with its customers. The paper contributes to the body of scientific innovation related literature which is concentrated to analyse open innovation processes and customer participation in it. Customer involvement and participation in an open innovation process can be analysed while using networking, value creation, or innovation inputs (knowledge for innovation perspective). The paper is based on the later approach, which allows us analysing the customer’s role. The paper proposes the structure for the classification of customer’s roles in the open innovation process, as analysed from the perspective of changing levels of involvement and variety of innovation inputs along the innovation development stages. Drawing on the analysis of customer roles and involvement levels at the certain stages of innovation process, the authors suggest a conceptual model for customer involvement in an open innovation.
QUANTITATIVE STUDY OF MONETARY POVERTY IN THE CZECH REPUBLIC AND SLOVAKIA Jitka Bartošová –

It is difficult to describe the actual state of economics. However, economics of a country is clearly reflected by the financial situation of households. Therefore, one way to analyse the actual state of economics can be done by quantitative illustration of the financial potential of households. The current economical crisis has the greatest negative impact on the poorest households below the poverty line. Our paper focuses on quantification and modelling of the financial situation of households in correlation with the poverty line. For modelling we use GLM-mixtures. Our research is based on data sets EU-SILC.
Curvelet imaging and processing : adaptive multiple elimination

Predictive multiple suppression methods consist of two main steps: a prediction step, in which multiples are predicted from the seismic data, and a subtraction step, in which the predicted multiples are matched with the true multiples in the data. The last step appears crucial in practice: an incorrect adaptive subtraction method will cause multiples to be sub-optimally subtracted or primaries being distorted, or both. Therefore, we propose a new domain for separation of primaries and multiples via the Curvelet transform. This transform maps the data into almost orthogonal localized events with a directional and spatial-temporal component. The multiples are suppressed by thresholding the input data at those Curvelet components where the predicted multiples have large amplitudes. In this way the more traditional filtering of predicted multiples to fit the input data is avoided. An initial field data example shows a considerable improvement in multiple suppression.
Understanding the "Sorting Hat": the Role of Family and Caste Network in School Choice Decision

Sorting of students over school type by their social standing creates the problem of social segregation and educational inequality. This paper, both theoretically and empirically, identifies factors which are responsible for sorting of students by socio-economic groups across different types of schools. We elaborate on the sorting mechanism by analyzing schools choice decisions where parents decide on the following: whether to send their children to private/public school and conditional on that whether to send them to good or bad school. We find that household characteristics such as the number of siblings, caste identity affect these two choices differently. For example we find that general caste students are more likely to attend private school but within the private category they are more likely to end up in bad schools. We develop our theory using a two period household level optimization framework and validate the prediction using a school survey data (Young Lives Survey). ∗This is a preliminary draft †University of Calcutta.

Enantioselective biotransformation of propranolol to the active metabolite 4-hydroxypropranolol by endophytic fungi

The enantioselective biotransformation of propranolol (Prop) by the endophytic fungi Phomopsis sp. , Glomerella cingulata, Penicillium crustosum, Chaetomium globosum and Aspergillus fumigatus was investigated by studying the kinetics of the aromatic hydroxylation reaction with the formation of 4-hydroxypropranolol (4-OH-Prop). Both Prop enantiomers were consumed by the fungi in the biotransformation process, but the 4-hydroxylation reaction yielded preferentially (-)-(S)-4-OH-Prop. The quantity of metabolites biosynthesized varied slightly among the evaluated endophytic fungi. These results show that all investigated endophytic fungi could be used as biosynthetic tools in biotransformation processes to obtain the enantiomers of 4-OH-Prop.
Cytotoxicity, Antioxidant Activity and Phenolic Content of Eight Fern Species from North of Iran

Background: Although ferns possess great potential because of some interesting medicinal properties, the phytochemical potential of ferns is relatively unexplored. Due to the lack of scientific evidence to support the traditional use of fern species in Iran, the present work focuses on evaluating the phenolic content, cytotoxicity and antioxidant properties of these plants. Methods: Toxicity of extracts was assessed by the brine shrimp test. Screening of antioxidant capacity of the rhizome and aerial parts of eight fern species was carried out using DPPH and ABTS radical scavenging assays. The total phenol content (TPC) of the methanol extracts were determined using the Folin-Ciocalteu method. Results: Compared to podophyllotoxin (with LC50 of 30 µg/ml), Athyrium filix-femina and Pteris cretica demonstrated a significant cytotoxic activity (with LC50 of 6.1 and 15.5 µg/ml, respectively). The methanol extract of Polystichum aculeatum was found to have significant antioxidant properties with IC50 value of 0.45 ± 0.02 µg/ml. Athyrium filix-femina exhibited the strongest ABTS radical scavenging activity (29.85 ± 1.39 µmol Trolox/g plant). Conclusion: Rhizome parts generally had higher DPPH scavenging capacity and showed better ABTS scavenging activity than aerial parts. Results showed that these ferns could be used for discovery of new and biologically active natural compounds.
The Effect of Corn Substitution with Palm Kernel Meal Treated by Enzyme on Production Performance and Carcass Quality of Broiler

The research was aimed to evaluate the effects of substitution level of corn with palm kernel meal (PKM) untreated and palm kernel meal (PKM) treated by enzyme on production performance and carcass quality of broilers. The method used in this research was experiment using nested of completely randomized design with 2 factors, the main factor was type of palm kernel meal factors consisting of PKM without enzyme (B1) and PKM by mannanase enzyme (B2), and substitution corn level L0 (without substitution), L1 (12.5%), L2 (25%), L3 (37.5%) and L4 (50%). The different among the treatments were tested by Duncan’s multiple range test. The results showed that corn substitution with PKM untreated and PKM treated by enzymes was significantly effect (P<0.01) on feed conversion ratio (FCR), tenderness, meat cholesterol of broilers and income over feed cost (IOFC) and significant effect (P<0.05) on feed intake, but there is no significant difference on body weight, percentages of abdominal fat and water holding capacity (WHC). Furthermore, effect of level corn substitition with PKM nested to PKM untreated and PKM treated by enzyme was significantly effect (P<0.01) on feed intake, body weight, FCR, and tenderness and significant effect (P<0.05) on IOFC, but there is no effect on percentages of abdominal fat, WHC and meat cholesterol. It can be concluded that the corn substitution with PKM treated by enzymes was better than the PKM untreated on production performance and carcass quality of broilers. The optimal level of PKM untreated as corn substitution was 12.5%. While replacement with PKM treated by enzyme can be used up to 25%.
USING HIGH-RESOLUTION SATELLITE IMAGERY IN A WELL-MAPPED COUNTRY

The use of imagery from high-resolution sensors on satellites such as IKONOS and QuickBird has proved that data from space-borne sensors can provide a viable alternative to aerial photography in many applications. This is especially the case in remote areas which have been poorly-mapped in the past. The benefits of satellite imagery include the rapid acquisition of data covering large areas; the frequent re-visit times of the satellites over almost any part of the globe, regardless of its remoteness; and the ability to collect data unhindered by local air traffic constraints. In areas of the world which have traditionally been well mapped, such as Western Europe, the benefits of satellite sensors may not be as clear. In this study, we look at the possibility of using high resolution satellite imagery in such a country; and assess the usefulness of such data in various applications within a national mapping agency.
Time variation in igneous volume flux of the Hawaii‐Emperor hot spot seamount chain

[1] Satellite gravity, ship track bathymetry, sediment thickness, and crustal magnetic age data were combined to calculate the residual bathymetry and residual mantle Bouguer gravity anomaly (RMBA) for the northwest Pacific Ocean. The Hawaii-Emperor hot spot track appears on the RMBA map as a chain of negative anomalies, implying thickened crust or less dense mantle. The hot spot swell is clearly visible in a broad band of half-width ∼500 km for about 2000 km downstream from the current hot spot location, corresponding to hot spot ages of 0–25 Ma. A much narrower expression of the hot spot is visible for the rest of the chain at hot spot ages of 25–80 Ma. Comparison of the observed RMBA with various compensation models reveals that the relatively narrow features of the Hawaii-Emperor seamounts are best explained as being supported by plate flexure, while the Shatsky Rise, Hess Rise, and Mid-Pacific Mountains oceanic plateaus are best fit by Airy isostasy with a thickened crustal root. Amplitude comparisons between the RMBA predictions of various compensation models and the observed RMBA for the Hawaiian swell are ambiguous. However, on the basis of the shape of the predicted anomalies, we favor a model of flexure in response to a buried load at 120 km depth. We further calculate igneous (i.e., crustal) volume flux along the axis of the Hawaii-Emperor hot spot by integrating cross-sectional areas of gravity-derived excess crustal thickness and seafloor elevation, respectively, with respect to the normal oceanic crust. The highest values of the calculated igneous volume flux along the Hawaiian and Emperor ridges (∼8 m3/s) occur at present and at about 20 Ma. The flux was reduced to only 50% of this maximum (∼4 m3/s) at 10 Ma. The calculated igneous volume flux is systematically smaller (maximum values of ∼4 m3/s) along the Emperor ridge. Overall, the Hawaiian and Emperor ridges appear to have experienced quasi-periodic variations in fluxes on timescales of 6–30 Ma. Furthermore, during the low-flux periods at 25–48, 57, and 75 Ma the height and size of individual hot spot seamounts appear to be noticeably less than those of the high-flux periods. We hypothesize that the variations in the fluxes of the Hawaiian ridge might be controlled by the thickness of the overlying lithosphere at the time of hot spot emplacement, while the variations along the Emperor ridge may be influenced by the dynamics of the slow absolute motion of the hot spot at the time.
Networked Gatekeeping and Networked Framing on #Egypt

Using prior seminal work that places emphasis on news framing and its relevance to sociocultural context, this study describes, maps, and explains evolving patterns of communication on Twitter through the events of the 2011 Egyptian uprisings, which led to the resignation of President Mubarak. Using a multimethodological approach, we conducted a network, content, and discourse analysis of randomly sampled tweets from approximately one million tweets over a month-long time period to study broadcasting and listening practices on Twitter. The findings suggested networked framing and gatekeeping practices that became activated as prominent actors and frames were crowdsourced to prominence. Quantitative findings underscored the significant role of ordinary users who both rose to prominence and elevated others to elite status through networked gatekeeping actions. In depth, discourse analysis of prominent actors and frames highlighted the fluid, iterative processes inherent in networked framing as frames were persistently revised, rearticulated, and redispersed by both crowd and elite. The ambience and affect afforded by the platform further supported conversational practices that enabled combined processes of networked framing and gatekeeping. The findings point to new directions for hybrid and fluid journalisms that rely on subjective pluralism, cocreation, and collaborative curation.
Research of Global Localization for Humanoid Robot Based on Vision

Vision perception plays a key role in the research on humanoid robot. A new version of particle filters called coevolution based adaptive particle filters (CEAPF) is proposed for robot localization. Using vision and odometer, a robust perception model extracting from environmental features, which are unscented by Kalman filter, is established by effective fixed scale feature-transformation method. Dimensional feature points matching algorithms are used to match the feature points based on KD-Tree to merge a species of cooperative coevolution competition mechanisms into particle filters. Coevolution adaptive particle filters are proposed to track the different assumptions and the samples in inter-species evolution can be moved towards the larger desired regions by using the crossover and mutation operators in evolutionary computation. Finally, results of success and precision localization are shown by experiment.
New approach for severe marine weather study using satellite passive microwave sensing

A methodology, based on model simulations and neural networks inversion, is proposed to jointly retrieve sea surface wind speed, sea surface temperature, atmospheric water vapor content, cloud liquid water content, and total atmospheric absorption at 10.65 GHz using Advanced Microwave Scanning Radiometer 2 measurements. In particular, estimation of the total atmospheric absorption at 10.65 GHz, which can be done with high accuracy due to the not so strong influence of liquid water and especially water vapor, helps to refine a new filter to considerably reduce masking ocean areas for severe weather systems, characterized by high wind speeds and moderate atmospheric absorption, appropriate for studying winter extratropical cyclone and polar low systems. A polar low case study has demonstrated significant improvement in the coverage of the ocean area available for geophysical retrievals: Only less than 1% of high wind speed pixels were masked comparatively to the 40–70% masking given by other methods.
Culture shock: negotiating feelings in the field

Culture shock is the depression and anxiety experienced by many people when they travel or move to a new social and cultural setting. Although many anthropologist experience culture shock whilst in the field, this is a subject that is rarely discussed in the academic setting. This article explores the issue of culture shock and offers some thoughts on how to relieve it, drawing on the author's own experiences.
Recent Issues in Emerging-Economies Macroeconomics Prepared

In this paper, we summarize the recent advancement of emerging-economies macroeconomics. We begin with stylized facts and models of real business-cycles for emerging-market countries and then move onto the discussion of various issues associated with overborrowings and sovereign debts. The common feature of these models is that their analysis is mainly focused on the framework of RBC models for small open economies combined with financial frictions. We also discuss nominal features of emerging economies that are associated with the behavior of nominal exchange rate and foreign reserves observed during the recent global financial crisis, as well as the practice and impact of conventional and unconventional monetary policy measures. We also present some extensions of existing emerging-economies models that allow for the significant role of conventional monetary and fiscal policies. Our results can be summarized as follows. First, the canonical specification of recent models with pecuniary externalities is modified to allow for channels through which conventional monetary and fiscal policies can affect the degree of pecuniary externalities. Second, we attempt to explain the behavior of nominal exchange rate “going up elevators and coming down stairs” shown in emerging economies during periods of zero lower bounds on the short-term nominal interest rate. Third, we modify a prototypical model of sovereign debt to show the negative correlation between the maturity of foreign debt and the accumulation of foreign reserves when the level of foreign debt is substantially high.
