Evaluation of Sensitive Skin in the Asian Population
Full text linkNguyen, Hanh T., Evaluation of Sensitive Skin in the Asian Population. Masters of Science (Clinical Research Management), December, 2008, pp. 80, 7 tables, 1 illustration, bibliography, 26 titles. Over 50% of the world’s population has self-perceived sensitive skin. Many of these individuals believe that their skin sensitivity was caused by topical products which caused them to avoid certain skincare products. However, previous research has shown that geographical environments such as weather changes, temperature, pollution, diet, and lifestyle can cause or enhance skin sensitivity. The results from this study failed to confirm the results from earlier studies. Instead, data indicated that geographical environment effects on skin sensitivity were minimal. Moreover, analysis of transepidermal effects on skin sensitivity were minimal. Moreover, analysis of transepidermal water loss for subjects with and without sensitive skin revealed that the skin barrier function for both skin types was not significantly different. Future studies are needed to investigate the sensitivity of the transepidermal water loss for evaluating skin barrier function. In addition, sample size for these studies should be increased to better represent the testing population. Moreover, if the Asian population is used in future clinical research studies, success will be governed by the effectiveness of the educational materials in minimizing the gap between Asian culture and clinical research in this population

The Hadley circulation in a changing climate
Full text linkThe Hadley circulation (HC) is a global-scale atmospheric
feature with air descending in the subtropics and ascending in the tropics, which plays a fundamental role in Earth’s
climate because it transports energy polewards and moisture equatorwards. Theoretically, as a consequence of anthropogenic climate change, the HC is expected to expand
polewards, while indications on the HC strength are equivocal, as weakening and strengthening are expected in response to different mechanisms. In fact, there is a general
agreement among reanalyses and climate simulations that
the HC has significantly widened in the last four decades
and it will continue widening in the future, but no consensus on past and future changes of the HC strength. Substantial uncertainties are produced by the effects of natural variability, structural deficiencies in climate models and reanalyses, and the influence of other forcing factors, such as anthropogenic aerosols, black carbon, and stratospheric and
tropospheric ozone. The global HC can be decomposedin three regional HCs, associated with ascending motion
above Equatorial Africa, the Maritime Continent, and Equatorial America, which have evolved differently during the
last decades. Climate projections suggest a generalized expansion in the Southern Hemisphere, but a complex regional
expansion/contraction pattern in the Northern Hemisphere
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
The current situation and future development of hospitality and tourism higher education in Vietnam
No full textThe objectives of the study are to analyze the current situation of hospitality and tourism higher education in Vietnam, to investigate problems and obstacles in producing graduates in the hospitality and tourism field of study, and to identify the future development of hospitality and tourism higher education in Vietnam. This study adopted a questionnaire survey of all institutions offering hospitality and tourism programs in Vietnam. The findings showed that 101 institutions offered the programs in 2007 and 13 other institutions will offer the programs by 2010. The recommendations from the study are: teaching staff needs to be improved in terms of qualifications, academic works, and teaching methodsthe curriculum needs to be evaluated, revised, and adjusted to the changing needs of the industry for manpowerand the institutions should add internships to the curriculum and let the industry become involved in hospitality and tourism education
Variations on the Author
Full text link“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
Full text linkWe 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
Rethink Cần Thơ
No full textGlobal climate change is an inescapable discussion today. Our history shows us the constant need to move along with this changing stream of life, as more and more extreme climate-related events happen every day. I witnessed the sad consequences of flooding problems due the Tsunami in Sendai, during my exchange period in Japan in 2012. Facing the problems of this disaster has been the start of this exploration in urban- and architectural water management. This thesis is an evolving process in finding answers to the key question “Which design solutions at a building level will help Cần Thơ adapt to the worldwide climate related flooding problems?”. The final result is identified in three separate objectives: 1) To create a toolbox with climate adaptive and particularly water robust solutions on a building level for the design process of houses in delta areas; 2) To propose a sustainable climate adaptive solution on a neighborhood level with particular attention to the existing tube houses in Ninh Kieu (District Centre of Cần Thơ, Mekong Delta, Vietnam) for the year 2100; 3) To propose a climate adaptive and water robust architectural re-design for the tube houses in Ninh Kieu for the year 2100.Architecture, Urbanism and Building Science
