Celiac disease in the developing countries: A new and challenging public health problem

In the past, celiac disease was believed to be a chronic enteropathy, almost exclusively affecting people of European origin. The availability of new, simple, very sensitive and specific serological tests （anti-gliadin, anti- endomysium and anti-transglutaminase antibody assays） have shown that celiac disease is common not only in Europe and in people of European ancestry but also in the developing countries where the major staple diet is wheat （Southern Asia, the Middle East, North West and East Africa, South America）, both in the general population and in the groups at risk. Gluten intolerance thus appears to be a widespread public health problem and an increased level of awareness and clinical suspicion are needed in the New World where physicians must learn to recognize the variable clinical presentations （classical, atypical and silent forms） of celiac disease. In the developing countries, both serological screening in the general population and serological testing in groups at risk are necessary for an early identification of celiac patients. The gluten-free diet poses a challenging public health problem in the developing countries, especially since commercial gluten-free products are not available.

The Outcomes of the Co-branding Strategy

The objective of this study is to investigate the outcomes of co-branding strategy in the assessment of the brand managers of analysed companies on European market and verification if a co-branding gives the opportunities for internal and external development. The analysis of correlation between the outcomes of co-branding and two major categories of co-branding strategy （ingredient branding and symbolic co-branding） are also important. In the paper the results of empirical studies are presented. Recent primary research （2009-2011） was conducted in 50 companies which are present in minimum three countries of Europe and have realized co-branding strategy for three years. Questionnaire surveys were carried out throughout all 120 identified companies. As a result, data from 50 companies were obtained, which amounted to 41.7% of all companies polled. The analysis of findings indicates the different outcomes in case of two major categories of co-branding strategy. The results show the general evaluation of the co-branded projects as well as the possibilities of the internal and external development. The results also emphasize the significance of symbolic character of the co-branding strategy. The recommendations in this study are set forth, of course, with the caveat as to the limitations of the sample. Nonetheless, it is believed that the results of this study will alert companies to the potential outcomes of co-branding taking into account the category of cooperation. This research has resulted in practical contribution. From the substantive stand point, this research has shed light on the outcomes of co-branding. This information can be useful for managers to understand which effects can be expected. From a theoretical and practical standpoint, this research contributes to brand alliances research and has provided a better understanding of outcomes of co-branding and the correlations between the possibilities of internal and external development and chosen category of co-branding strategy. This text may contribute to further research in this area and as a kind of motivator for further discussion on this topic.

Structural Characteristics and Molecular Mechanism of Hepatitis B Virus Reverse Transcriptase

Hepatitis B virus (HBV), a typical member of the Hepadnaviridae family, is responsible for infections that cause B-type hepatitis which leads to severe public health problems around the world. The small enveloped DNA-containing virus replicates via reverse transcription, and this unique process is accomplished by the virally encoded reverse transcriptase (RT). This multi-functional protein plays a vital role in the viral life cycle. Here, we provide a summary of current knowledge regarding the structural characteristics and molecular mechanisms of HBV RT. Improved understanding of these processes is of both theoretical and practical significance for fundamental studies of HBV and drug discovery.

Reverse Logistics Related to Waste Management with Emphasis on Developing CountriesmA Review Paper

This paper provides an overview of the state of art of reverse logistics and current status of waste management problems with special emphasis on developing countries. Logistics activities have been practiced and played a fundamental role in the global economic development for over 5,000 years. It has then been transformed into different logistics branches and elaborates the emergency of reverse logistics as one of the most important. The paper presents the evolution of logistics into reverse logistics and how it relates to waste management both in the developed and developing world. Reverse logistics is a relatively new phenomenon in the research area which is mainly referring to damaged goods, the take back of products that should be returned to the manufacturers or distributors. Reverse logistics is relatively more practiced in an organized way in the developed world than in the developing countries in that the latter provided less value additions on reversed products.

Commercial Risks Arising from Chartering Vessels

This paper constitutes a review of the most important aspects of commercial risks arising from charterparties, operations and claims issues. That means the risks allocated between the shipowner and the charterer throughout the chartering process （pre-fixture, fixture, execution of charter, post-fixture, claims handling）, from a financial, operational and legal perspective. The interpretation of the above mentioned matters is considered of critical importance in chartering practice. The analysis is seen from a commercial stand point. Therefore, it is mostly addressed to the shipping practitioners, maritime economists, academics, students and researchers who seek to form a comprehensive view on the subject. It may also form a basis for further study on chartering aspects （legal, economic, managerial and practical）.

Communicating Geologically-Underpinned Issues： Drivers and Mechanisms

Geologists can offer key insights in regard to several high profile environmental issues that are faced today. At the same time, like scientists in most other disciplines, many geologists are not naturally adept at communicating in an effective manner with non-geologists. This paper firstly identifies the more subtle facets of topical major issues （the drivers） where geologists can contribute important perspectives. Next, the detractions to effective communication are identified, along with the recommended means to overcome them （the mechanisms）. Many topical issues are in fact geologically-underpinned （e.g. obviously, geohazards）, so geologists ought to have something meaningful to say. By the same token, if geologists have difficulty communicating with other scientists, how can they possibly hope to communicate with journalists and with the public at large？ Proper scientific contextualization is an ideal starting point, but this fundamental framing step does not always suit protagonists who have non-scientific agendas. Thus, geologists not only have to convey their science （geology） in an understandable way, but to do so in a truly effective manner must recognize and take into account possible predispositions that their audience may have.

An Alternative Means of Assessing Climate Models

The authors compared two different sets of assessment of the abilities of contemporary climate models. One group is made of experts, and their results are provided in two expert reports, while the other is the subjective assessment made by ＂physical climate scientists＂ in general, sampled in a series of three survey questionnaires. The expert group is considerably more optimistic than the general group; the former suggesting progress, while the perception of the latter group is more or less stationary.

Effect of Socio-Economic Variables on Fish Production of Small Farmers in Tocantins State, Brazil

Fish farming is a strategic activity for both the economy and food security of the Tocantins state. Nowadays, there are about eighty small fish farmers in the region of Divin6polis in Tocantins state. The technological level of fish farmers is low and it was found that only 30% of farmers could ever get to the point of selling fish. Therefore, the objective of this paper is to investigate which socioeconomic factors have influence on the fact of fish farmers in the region of Divin6polis and in Tocantins state reach a level of efficiency in production enough that the fish can be good for sale in the local market. To estimate this relation the logit model was chosen, with methodology based on the empirical model used in Musaba and Namukwambi. Following the production of fish farms in the Western of Tocantins state, the collect of the data, during 2012, were conduct with interviews of 30 fish farms, visiting them in their homes and applying a questionnaire. Through the use of econometric models of probability for limited dependent variables, it was found that factors such as participation in federal programs to transfer income, total area of water and production in ponds are key factors in determining the likelihood of producer to sell fish.

The Tragic Flavors in The Merchant of Venice

The Merchant of Venice （1914）, as one of the greatest works by Shakespeare, is a comedy. It addresses various themes. It is much more than a study of the struggles between Christians and Jews; it also deals with love and self-sacrifice, hatred and revenge, and friendship and marriage. It is a victory of Christians against Jews. But, at a more profound level, the play is ultimately a tragedy which functions as a cautionary exposure on the social problems of prejudice, hypocrisy and the family relationships. The paper begins by addressing the prejudice that is a dominant theme throughout the play. It also contends that the hypocrisy is prevalent in Venetian society. Then, Shylock, as the tragic hero in the play is analyzed. The final part deals with the problem of family relationships. By exposing grave deficiencies in Venetian Society, the play obliges us to make a critical moral judgment on humanity and establish correct philosophy of life and values

Analysis of the EU's Security-Development Nexus Aid Policy in Africa and Agenda 2063

With the security situation in Africa looking pessimistic since the beginning of the 21st century, the EU has adjusted its ODA policy in Africa by linking it to security issues. The EU has been carrying out a number of security-development aid projects and these have seen some positive results. However, shortcomings have been identified. Even so, it is of historic significance that African nations are working more closely with the EU in the areas of security and aid under the framework of Agenda 2063.

The False Promise of Kant＇s Humanity Formula

Kant＇s Humanity Formula of the Categorical Imperative is arguably its most widely preferred formulation, having been defended as a moral principle and employed in the evaluation of particular moral problems by a number of leading contemporary ethicists. For them and many other readers of Kant, the idea that we are not to treat persons as mere means to our own ends but are rather to respect their rational agency as intrinsically valuable holds great promise for qualifying as, in Kant＇s words, ＂the supreme principle of morality.＂ In the present paper I argue that the Humanity Formula cannot deliver on this promise. After setting forth three conditions of adequacy for any genuine supreme principle of morality, I argue that the Humanity Formula, on three textually grounded interpretations each of which has been advocated by a prominent Kantian ethicist, does not satisfy these conditions. Whichever of these textually grounded interpretations is taken, the Humanity Formula is open to compelling counterexamples.

Research Progress on the Problem of Fluid,Heat and Energy Distribution near the Earthquake Source Area

As the basic problems in seismology, fluid, heat and energy distribution near earthquake sources during earthquake generation have been the leading subjects of concern to seismologists. Currently, more and more research shows fluid around earthquake source areas, which plays an important role in the process of earthquake preparation and generation. However, there is considerable controversy over the source of fluid in the deep crust. As for the problem of heat around earthquake source areas, different models have been proposed to explain the stress heat flow paradox. Among them, the dynamic weakening model has been thought to be the key to solving the heat flow paradox issue. After large earthquakes, energy distribution is directly related to friction heat. It is of timely and important practical significance to immediately implement deep drilling in-site surveying to gain understanding of fluid, friction heat and energy distribution during earthquake generation. The latest international progress in fluid, heat and energy distribution research has been reviewed in this paper which will bring important inspiration for the understanding of earthquake preparation and occurrence.

Self-configuring Two Types of Neural Networks by MPCA

ANN （artificial neural network） is a technique successfully employed in many applications on several research fields. An appropriate configuration for neural networks is a tedious task, and it often requires the knowledge of an expert on the application. In this paper, a technique for automatic configuration for two types of neural networks is presented. The multilayer perceptron and recurrent Elman are the neural networks used here. The determination of optimal parameters for the neural network is formulated as an optimization problem, solved with the use of meta-heuristic MPCA （multiple particle collision algorithm）. The self-configuring networks are applied to perform data assimilation.

Characteristics and Development Modes of Standardization forChina's National High-Tech Zones:A Review

Indigenous innovation focused on the development of technical standards has become the core of China's innovation policy,since China released the "Outline of the National Program for Longand Medium-Term Scientific and Technological Development (2006-2020)" in 2006.Meanwhile,standardization issues are greatly emphasized by high-tech zones which serve as the major carriers of national economic growth as well as innovation clusters in the context of fast-growing international standardization.By means of the effective guide of the government,the standardization of high-tech zones in China now presents a wide range of operating modes.Specifically,they can be divided predominantly into the government promotion mode,the alliance collaboration mode,the research-standard-industry linkage mode,and the talent training mode,in terms of the main body of work and influence factors.

An Ecocritical Reading ofljala Chant： An Example of Ogundare Foyanmu＇s Selected Ijala Chant

African artists demonstrate social commitment and sensibility in various ways as they create works that both sensitise and conscientise people in their milieu. Although ecocriticism itself is a relatively new theory, African artists have been preoccupied with issues bothering around environment in order to protect and preserve it. ljala genre has been studied by different scholars such as Babalola S. A. （1966）, Olukoju E. O. （1978） and Alagbe ＇Sayo （2007） from diverse perspectives; however, its ecocritical relevance has not been investigated. It is in view of the foregoing that this paper carries out an ecocritical reading of ljala chant： an example of Ogundare Foyanmu＇s selected ljala chant. The paper aims at establishing environmental consciousness in the work of this oral artist. It is observed that though ecocritical theory itself is new in African literature, African artists have shown commitment towards environmental protection in their works from time immemorial. Foyanmu conscientises the people to desist from sneeringly underrating the effect of water hazard. The paper, therefore, has no doubt, established that the subject ofljala genre is not in any way limited to hunting or hunters＇ life. It is also used to address other relevant socio-political and economic issues

Consumption and Leisure Patterns of Youth in Turke

Consumption-oriented daily life resulted in new forms of consumption spaces in many cities. Among these spaces, shopping malls are significant with their improved physical and social environments for consumption and leisure for all the family. One of the important marginalized groups, to whom the mall appeals, are young people. Within this framework, the main purpose of this study is to investigate the consumption and leisure practices and experiences of young people in Turkey from their point of view. Migros, a shopping mall in Ankara, was chosen as the site for this research, where both consumption and leisure practices are overlapping within the same space. The research was carried out through observation and in-depth interviews with 104 teenagers. The results indicated that shopping malls were the main leisure and consumption site for teenagers. Teenagers＇ choice of malls as their favorite leisure and consumption space were found to be the result of some factors such as restrictions which were provoked by their parents, security concerns, location of the mall, and accessibility and limited financial resources. These factors seemed to lead to restrictions in the choice of places to spend their leisure time and limit the use of leisure spaces other than malls. As a consumer group in the mall space, teenagers had some complaints about the prices of facilities which seemed to be influential on their choices of consumption and leisure practices in the mall environment.

The Relationship Between EPI and GDP Growth： An Examination on Developed and Emerging Countries

Environmental issues are one of the most important aspects of the long-term development of a country and have an important role in a nation＇s wealth. Different environmental performance indicators present different methodologies and aim to measure countries＇ environmental performances with different approaches. One of the environmental indices, Environmental Performance Index （EPI）, ranks countries＇ performance on high-priority environmental issues in two areas： protection of human health and protection of ecosystems. The purpose of this paper is to discuss the environmental aspect of sustainability with the EPI and analyze the relationships and differences of the chosen 14 （seven are developed and seven are emerging） countries＇ EPI scores and Gross Domestic Products （GDPs）.
