No full textVietnamese coffee in the path of International Integration : The United States export market analysis
No full textThe purpose of this thesis was to provide information about Vietnamese coffee industry, explore the potential export of this commodity to the key market, the United States and its contribution to the worldwide market.
The data in the theory part were gathered from the literature. The theory part is written according to literature. This section included market analysis tools which support to study more about the business environment.
The empirical part was created by collecting available data and official sources from Vietnam and the USA. This part deals with experiences the two countries. The section is experiences, the explanation for the theory.
Firstly, the thesis will analyze the Vietnamese coffee industry compared to other countries in the same field about coffee production, export volume and value. Secondly, it figures out the United States’ import trend and preference, these finding will indicate Vietnam’s position in the USA. Thirdly, some market analysis tools will support the reader to understand potentials, opportunities and current obstacles that control the development in coffee production
Does the Addition of Piracetam Safely and Effectively Improve Behavioral and or Cognitive Functions in Schizophrenia?
No full textOBJECTIVE: The objective of this selective evidence based medicine (EBM) review is to determine whether or not the addition of piracetam safely and effectively improve behavioral and or cognitive functions in schizophrenia.
STUDY DESIGN: The selected review from all English language, primary literature sources that were published between 1979 and 1999.
DATA SOURCES: Three double blind randomized controlled trials (RCT) and one case controlled clinical study that compared piracetam to a visually matched placebo was selected and found using Medline, PubMed, Ebscohost, and Cochrane databases.
OUTCOMES MEASURED: Each of the trials assessed the effect of Piracetam on behavioral and or clinical functions of Schizophrenia patients by utilizing the following assessment tools: Brief Psychiatric Rating Scale (BPRS), The Behavior Rating Scale, The Wing Symptom Rating, and Positive and Negative Syndrome Scale (PANSS).
RESULTS: The trials demonstrated that the mean change before treatment with the use of piracetam as opposed to the visually matched placebo, as compared to after the treatment was large, with all statistically significant P values ≤ 0.05. This demonstrated that there was improvement in behavioral and cognitive functions achieved with the treatment of piracetam versus placebo.
CONCLUSION: Based on the studies, all reported that with the use of piracetam in schizophrenia, there showed improvement of some type of behavioral and or cognitive functions above baseline. Although the pattern of outcome was similar in all the studies, there requires a continued and more updated investigation to be aimed at determining a specific dose of piracetam therapy, a specific patient population for which piracetam is most effective and to further elaborate its safety profile outside a controlled research setting
La maison tube des nouveaux quartiers d'Hanoï : Effets de paramètres architecturaux sur l'ambiance thermique
No full textDans les pays tropicaux, comme le Vietnam, les gens vivent en permanence avec la chaleur et l'humidité, deux causes principales de conditions inconfortables. L'architecture traditionnelle vietnamienne a réduit les impacts négatifs du climat sur l'ambiance thermique à l'aide d'espaces ouverts tels des jardins, des cours intérieures et des puits de lumière. Toutefois, dans les maisons en milieu urbain, l'adaptation au climat a été minimisée à cause de leurs traits typologiques. Ces maisons, qui sont des habitations typiques de Hanoi depuis plusieurs décennies, sont étroites et profondes. De ces faits, pour les maisons de ville, en arriver à un design permettant d'obtenir à la fois le confort thermique et l'économie énergétique est toujours un défi pour l'architecte. Une bonne stratégie architecturale est donc particulièrement importante. Cette stratégie doit à la fois procurer une ambiance thermique intérieure confortable et minimiser l'utilisation d'appareils de climatisation, considérée comme une perte du point de vue énergétique. L'objectif principal de cette recherche est d'étudier l'influence de différentes stratégies architecturales sur la qualité de l'ambiance thermique dans la maison tube des nouveaux quartiers d'Hanoi. Cette étude a été réalisée à l'aide de simulations thermiques dynamiques avec le logiciel Derob-LTH. L'ensemble des résultats obtenus a permis de confirmer la plupart des hypothèses de recherche. Selon ces résultats, on peut conclure que les stratégies architecturales ont influencé l'ambiance thermique intérieure des maisons urbaines. De plus, on peut voir que certaines stratégies à faible coût et très simples à appliquer peuvent améliorer significativement l'ambiance thermique intérieure. Finalement, ce mémoire suggère une combinaison de stratégies architecturales pouvant augmenter significativement l'ambiance thermique intérieure des maisons urbaines
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
