Abstract:
Ornithological data of Banco National Park have not been updated since 2002. From March to January 2013, point count method was used. One hundred and ninety three species of 46 family and 14 orders were identified. Among these species, 36 are newly observed, increasing birds diversity to 203 species. The Pycnonotidae family, with 21 species, is the most diversify. The species observed are from different biogeography origin (170 residents, 23 migratories). Eighty seven species are restricted to the Guinea-Congo Forest Biome. Three species (Bleda eximius, Criniger olivaceus and Psittacus erithacus) are vulnerable according to the IUCN red data book.
This paper presents an educational data mining model to classify as early in the academic term as possible students into three groups: the 'low-risk' students who have a high probability of succeeding; the 'medium-risk' students who may succeed thanks to the measures taken by the university; and the 'high-risk' students who have a high probability of failing using decision tree method where several classification rules were generated. The predictive model have been developed using SAS Enterprise Miner. The model was tested using El- Shorouk Academy student data, the institute of computer science and information technology, academic year 2013-2014, and these data collected for all subjects among the first and second year students, using sample of 2295 students. The Proposed model includes various input attributes such as student mid-term score, student attendance in lectures, student attendance in sections, student high school grades, student status(Residual-newcomer), student interest in his department, type of high school. Accuracy was evaluated using the "misclassification rate (MISC)" and "average squared error (ASE)" methods for the validation data set in SAS Enterprise Miner. This model helps to identify students who need special advising or counseling by the instructor so that they can be warned to be at risk before the final exams.

Abstract:
Predicting students' academic performance is critical for educational institutions because strategic programs can be planned in improving or maintaining students' performance during their period of studies in the institutions. Data mining technologies can be used to monitor students and simultaneously analyzing their academic behavior, thus providing a basis for implementing necessary intervention procedures if required.
This paper presents an educational data mining model to classify as early in the academic term as possible students into three groups: the 'low-risk' students who have a high probability of succeeding; the 'medium-risk' students who may succeed thanks to the measures taken by the university; and the 'high-risk' students who have a high probability of failing using decision tree method where several classification rules were generated.

International Investment Arbitration: Refuge Versus Deadlock
414-426
Ghada Awada
Abstract:
This study investigated the impact of arbitration and other alternative dispute resolution methods on the extant of foreign investments in a country. The international trade community resorts to arbitration as a security refuge; accordingly, the international arbitration agreements are drafted and ratified . The study proved that the interrelation between investment definitions and investments shape to a certain extent the amount of investments in a country. The findings of the study indicated that it is recommended to find a legal mechanism similar to those created by the Lebanese Council of Ministers, and the legislator shall be aware of the international conventions and the form of investment before it is signed. There is also a compelling need to clarify Article 21 of the Amended Unified Convention for the Investment of the Arab Capitals in the Arab states as drafted on 6/12/2012. It is imperative that Lebanon not ratify item 8 of Article 3 of the Annex pertaining to the Amended Unified Convention for the Investment of the Arab Capitals in the Arab states as drafted on 6/12/2012. It is crucial that a summary of the arbitral decisions issued by international institutions relating to arbitration be obligatory.

Coal Quality Monitoring With Improved Control Charts
427-434
Liaquat Ahmad, Muhammad Aslam and Chi-Hyuck Jun
Abstract:
The repetitive group sampling control charts on the variable data has been introduced by Ahmad et al. [1]. In this paper, we will give the application of control chart proposed by Ahmad et al. [1] in coal quality monitoring. The choice of the design parameters of the proposed chart are based on the average run length (ARL). The optimal design parameters of the proposed chart are obtained by imposing the constraint on the ARL, which gives tighter limits as compared to traditional control limits given by Elevli [2]. The proposed chart is efficient in detecting the out-of-control process as compared to the traditional control chart proposed by Elevli [2].
Keywords: Control chart; Average run length; Calorific content; Repetitive sampling control chart.

Abstract:
This study aimed to identify the demographic profile, describe experienced flood conditions, and assess flood preparedness knowledge, attitude and behaviors among the elderly. A cross sectional study was conducted in Saraburi province. 342 elderly people aged 60 years and above were face to face interviewed. Pearson’s correlation coefficient was used to explore the associations between knowledge and attitude, knowledge and behaviors, and attitude and behaviors on flood preparedness among the elderly. Majority of respondents’ knowledge, attitude and behaviors scores were in moderate level Findings showed the elders did not prepare necessary items before flood including medicines (40.4%), clothes (38.6%), food supply (32.2%), documents (27.5%), and flash light and battery (50%). During the flood the elders did not properly practice preparedness behaviors including not cutting down home electricity (27.5%), not hands washing before meal (32.2%), not careful for accidents (22.2%), and not wearing boots (43%). After the flood, the elders did not meet doctor or local health professional when they were sick (19.6%), Pearson’s correlation coefficient showed significant positive low correlations between knowledge and attitude, knowledge and practice, and attitude and behaviors (0.348, 0.422, and 0.261 respectively). In order to cope with flood appropriately, knowledge, attitude and behaviors regarding flood preparedness is essential. The finding of this study could be utilized to create an appropriate flood disaster preparedness actions and response, as well as to develop flood education for the elderly living in rural community.

Product Variety and Price Markups: Isomorphism between the Hotelling and the Chamberlinian Model
445-452
Asterios Sormas
Abstract:
The conventional wisdom in the literature of Industrial Organization is that the two fundamental models of monopolistic competition, Hotteling’s spatial allocation model and the Chamberlinian model, are not compatible to each other. In the present paper, and against this tradition, I show that an appropriate modification of the Chamberlinian model of monopolistic competition can make it isomorphic to Hotelling’s model of spatial location, at least with respect to a certain family of problems. I demonstrate the isomorphism between the two models, by using as a benchmark example the relation between market entry, product variety, and price markups.

Interest-Based Extraction of Isocontour Components
453-464
Liangfu Chen and Bong-Soo Sohn
Abstract:
We describe a new method for interactively extracting the boundary surface of an object that is interesting to a user from 3D volumetric imaging data. In practical study of medical imaging, surface of a specific 3D object is often represented by a connected component of an isocontour, called a contour. We define and utilize geometric and topological properties of contours to recognize the saliency of contours and help users to select salient contours that represent object surfaces interesting to the users through our newly designed contour tree interface. A contour surface is often so large that it would be a time-consuming task to propagate and triangulate the contour. For contour surface extraction, our algorithm takes advantages of both multi-core CPU and many-core GPU to achieve enough interactivity.

HO SOONMIN
Abstract:
Ni3Pb2S2 films were successfully deposited by a simple chemical bath deposition method on glass slide. The effect of deposition parameters on the film growth has been studied using atomic force microscopy and X-ray diffraction. The X-ray diffraction analysis confirmed the structure of Ni3Pb2S2 films. Atomic force microscopy images revealed that the film thickness depended on the bath temperature, pH and deposition time.
Keywords: Chemical bath deposition, thin films, X-ray diffraction, atomic force microscopy.

La Gestion Participative, une Stratégie Efficace de Préservation des Réserves de Biosphère: Cas de la Réserve de la Comoé en Côte d'Ivoire
481-497
GAUZE TOUAO Kah Martine, ALOKO N’GUESSAN Jérôme and TOURE TIVEGBO Augustin
Abstract:
One of the Comoé biosphere reserve (RBC) management strategic lines is managing and coordinating actions so as to protect and improve natural environments for a long term rational use. This vision includes “promoting rural populations active participation in the sustainable management of their region’s natural resources (including coppice and forest plantations)”. So, after years of interventionist management, not taking local populations’ participation into account, now we acknowledge that they can play a decisive role in the perpetuation of the Comoé biosphere reserve. But how is their participation a fundamental step to success in the preservation policy of the Comoé biosphere reserve?
The aim of this article is precisely to show that through participatory management, that is a management which includes local populations, the spatial behavior of those populations is channeled so as to promote the preservation the biosphere reserve. This reinforces the hypothesis that the survival of protected areas under strong anthropogenic pressure largely depends on the collaboration with local populations and mostly on their involvement in the management of the protected areas.
