Finding the Core-Genes of Chloroplasts

Computer Science , 2014,
Abstract: Due to the recent evolution of sequencing techniques, the number of available genomes is rising steadily, leading to the possibility to make large scale genomic comparison between sets of close species. An interesting question to answer is: what is the common functionality genes of a collection of species, or conversely, to determine what is specific to a given species when compared to other ones belonging in the same genus, family, etc. Investigating such problem means to find both core and pan genomes of a collection of species, \textit{i.e.}, genes in common to all the species vs. the set of all genes in all species under consideration. However, obtaining trustworthy core and pan genomes is not an easy task, leading to a large amount of computation, and requiring a rigorous methodology. Surprisingly, as far as we know, this methodology in finding core and pan genomes has not really been deeply investigated. This research work tries to fill this gap by focusing only on chloroplastic genomes, whose reasonable sizes allow a deep study. To achieve this goal, a collection of 99 chloroplasts are considered in this article. Two methodologies have been investigated, respectively based on sequence similarities and genes names taken from annotation tools. The obtained results will finally be evaluated in terms of biological relevance.
Arts and Scholastic Performance  [PDF]

Abstract: Pleasant environmental music during an academic test helped students to overcome stress. As a result the grades they obtained were higher. It was also demonstrated that students selecting music as optional course performed better, than music-less control students over three consecutive years. Yet, there remained ambiguities as for the causes of the higher test performance of these students. Our study confirmed a Mozart effect, and further showed a latency of two to three years for such a positive influence to take place, suggesting that it is the practice of music itself that helps cognition. We showed also that other art courses, when freely chosen, have similar positiveinfluences on students’ performances, illustrating that the principles of learning are linked to hedonism and to will effort in a more general manner.

Asian Journal of Business Management , 2011,
Abstract: The principal objective of this research is to explore Ethiopian service sector customer satisfaction levels. This research paper reviewed the pertinent literature on services marketing as well customer satisfaction. Then, through structured questionnaire and in-depth personal interviews with 600 Ethiopian telecom, banking and insurance, civil aviation and tourism, and health services customers of both the sexes (300 male and 300 female) in the Addis Ababa region collected the opinions on service interaction, service delivery process, customer complaint handling procedure, overall satisfaction levels and also customers opinion on improvement on service providers ability in the last five years. This study used both quantitative as well qualitative survey research designs. The study measured customer satisfaction levels with recalled service encounters and the method of data collection was convenience type. The data collected was analyzed with the help of Microsoft Excel software packages. Hypotheses were developed based on literature review and applied to empirical data of Ethiopians’. The findings of the analysis showed that 36% customers of Ethiopian service sector were dissatisfied with employees’ interaction skills. Furthermore another 47% of the customers were also disappointed with service delivery system and 52 and 61% customers were not pleased with the service recovery process and complaint handling procedure, respectively. And 49% of the customers expressed overall dissatisfaction on the services provided by Ethiopian service sector. Besides 94% respondents robustly acknowledged Ethiopian service sector is improving immensely in providing all kinds of services in the last five years. Because of significant dissatisfaction percentage levels among customers, sector’s think tank has the opportunity to seriously evaluate its existing activities, procedures, programs related to service interaction, delivery and recovery process, complaint handling and other areas which crafted unhappiness in the market.

V.S. Mangnale,Rajasekhara Mouly Potluri
Asian Journal of Business Management , 2011,
Abstract: The primary objective of this research is to explore the perceptions of both the higher education institutions and students on the various quality deliverables in the Indian higher education system along with careful observation of the role of Internal Quality Assurance Cell (IQAC) in sustaining quality delivery of education service. The research study reviewed the germane literature on higher education and quality management in higher education. Then, the researchers used two separate questionnaires to gather the opinions of 10 higher education institutions and 250 students on quality of education service delivery in the first quarter of this year from the Pune district of Maharashtra state. The collected data was analyzed with the support of Microsoft Excel software packages. The findings of the analysis confirmed that institutions were confidently provided academic activity reflecting their goals and objectives with highly qualified faculty through an eclectic approach with the support of research with ample focus on library and community services. Students also expressed different wavering perceptions on the academic activity, faculty communication skills, motivation and mentoring etc. Only 33 and 80% students uttered positively about the faculty subject knowledge and sports, and infrastructure facilities provided by the institution. In a nut shell, both institutions and students insisted for more constructive role from the Internal Quality Assurance Cell (IQAC) in protecting the quality of higher education.
Dissociation between Performances in Water Maze and Spontaneous Alternation in BALB/C versus A/J Mice  [PDF]

Journal of Behavioral and Brain Science (JBBS) , 2012, DOI: 10.4236/jbbs.2012.22018
Abstract: Learning processes are extensively studied in behavioral neuroscience. As experimental models, Morris Water Maze (MWM) and Spontaneous Alternation (SA) represent two of the most frequently used laboratory tests to respectively address spatial vs non-spatial tasks. Several factors have been shown to impact on those learning, including strain, gender, apparatus, conditioning, vision, lighting conditions and stress level. In order to focus on the later, we compared the acquisition of two learning tasks (MWM and SA) in BALB/c and A/J mice, which are known as fearful and stress-sensitive strains. Here, we report that BALB/c mice exhibited higher performances than A/J mice in the MWM (i.e. spatial reference memory task), whereas A/J mice performed better in the SA (i.e. spatial working memory task). These results indicate dissociated processes in the acquisition of spatial vs non-spatial tasks, and emphasize a varying influence of emotional reactivity on different forms of cognition.
A Study on Ethnocentric Tendencies of Ethopian Consumers
V.S. Mangnale,Rajasekhara Mouly Potluri,Habtamu Degufu
Asian Journal of Business Management , 2011,
Abstract: The purpose of this research is to deduce and analyze the ethnocentric inclinations of the Ethiopian consumers for products and services by determining the applicability of Consumer Ethnocentric Tendencies Scale (CETSCALE). This study thoroughly reviews the existing literature on ethnocentrisms. The CETSCALE (Consumer Ethnocentric Tendencies Scale) developed by Shimp and Sharma was adopted to measure the magnitude of ethnocentrism in both the product and service markets. 500 questionnaires were distributed and only 446 questionnaires were found to be useable for the analysis. Before using the CETSCALE as a measure of ethnocentricity, the reliability of the scale was assessed. The information obtained from the sample was analyzed by using SPSS 16.0 statistical package. The result shows that CETSCALE is a reliable instrument to measure the ethnocentric tendencies of Ethiopian consumers. The magnitude of ethnocentrism for the sample population indicated that Ethiopians exhibit moderate ethnocentrism. The analyses of the demographic variables show that women are more ethnocentric than men. However, no significant relationship was found between ethnocentrism, age, income, and educational levels. Further, consumers did not exhibit different levels of ethnocentrism for the product and service markets in Ethiopia. This research study serves as a basis for Ethiopian marketers to understand the ethnocentric levels of their consumers while purchasing both products and services which are constructive to them to develop, design and modify their marketing offers. The study is the first to investigate the ethnocentric levels of consumers for products and services in Ethiopia and also in East Africa. Thus, it makes a significant contribution to the literature.
The RUB Cage: Respiration–Ultrasonic Vocalizations–Behavior Acquisition Setup for Assessing Emotional Memory in Rats

Abstract: In animals, emotional memory is classically assessed through pavlovian fear conditioning in which a neutral novel stimulus (conditioned stimulus) is paired with an aversive unconditioned stimulus. After conditioning, the conditioned stimulus elicits a fear response characterized by a wide range of behavioral and physiological responses. Despite the existence of this large repertoire of responses, freezing behavior is often the sole parameter used for quantifying fear response, thus limiting emotional memory appraisal to this unique index. Interestingly, respiratory changes and ultrasonic vocalizations (USV) can occur during fear response, yet very few studies investigated the link between these different parameters and freezing. The aim of the present study was to design an experimental setup allowing the simultaneous recording of respiration, USV, and behavior (RUB cage), and the offline synchronization of the collected data for fine-grain second by second analysis. The setup consisted of a customized plethysmograph for respiration monitoring, equipped with a microphone capturing USV, and with four video cameras for behavior recording. In addition, the bottom of the plethysmograph was equipped with a shock-floor allowing foot-shock delivery, and the top received tubing for odor presentations. Using this experimental setup we first described the characteristics of respiration and USV in different behaviors and emotional states. Then we monitored these parameters during contextual fear conditioning and showed that they bring complementary information about the animal’s anxiety state and the strength of aversive memory. The present setup may be valuable in providing a clearer appraisal of the physiological and behavioral changes that occur during acquisition as well as retrieval of emotional memory.

Abstract: knowledge production is a key element of the dynamics of contemporary societies that until now have been based on uneven levels of scientific and professional knowledge. the aim of this work is to understand, from a sociological point of view, the various aspects of the relationship between creativity, communication and knowledge production, starting from the following questions: what is the role of communication in the elaboration of discoveries or intellectual advances? what is the role of individuals and networks in these advances? and finally, what are the characteristics, especially the communicational ones, of the more creative institutions? the text is based on the works of philippe breton (communication and the status of knowledge), randal collins (network creativity), rogers hollingsworth (cognitive complexity, institutional diversity, quality of the research environment in terms of scientific exchange and discussion). these questions are not restricted to a strictly academic debate. they are also directly related to the practices of research environments, professors-researchers and students of master’s and doctor’s degree.
Um candomblé na Bélgica: tra?os etnográficos de tentativa de instala??o e suas dificuldades
Halloy, Arnaud;
Revista de Antropologia , 2004, DOI: 10.1590/S0034-77012004000200004
Abstract: in this article, i propose to go through some difficulties encountered in a setting up attempt of a candomblé (afro-brasilian cult) in belgium. my analysis will propose three main categories of problems: situations undermining the legitimation of the cult's chief and the respect of some ritual constraints; various "adaptation" attempts to human and material resources available; difficulties of learning some categories of knowledge that are not based on a linguistic formulation. to focus in this study on problematic situations does not aim to drow a chaotic picture of a "disrooted" cult but to account ethnographicaly for the dynamic and the multi-facial and builded characteristics of religious experience.
Les réseaux négociants de trois maisons huguenotes de Cadix, à la fin du xviiie siècle : des réseaux languedociens, protestants ou fran ais ?

Abstract: Dans le dernier tiers du xviiie siècle, pour faire leur commerce, les négociants fran ais de Cadix – le port qui servait de tête de pont au commerce colonial espagnol – s’appuyaient sur deux types de réseaux marchands : d’une part, des correspondants résidant en Europe, qui leur fournissaient les biens manufacturés recherchés sur les marchés américains et qui recevaient, en échange, les piastres et autres denrées coloniales que les cargadores leur rapportaient en retour ; d’autre part, de...
