Full Text Available The review article reveals the content of the concept of Food Regime, which is little-known in the Russian academic reference. The author monitored and codified the semantic dynamic of the terminological unit from its original interpretations to modern formulations based on the retrospective analysis. The rehabilitation of the academic merits of D. Puchala and R. Hopkins — authors who used the concept Food Regime for a few years before its universally recognized origin and official scientific debut, was accomplished with help of historical and comparative methods. The author implemented the method of ascension from the abstract to the concrete to demonstrating the classification of Food Regimes compiled on the basis of geopolitical interests in the sphere of international production, consumption, and distribution of foodstuffs. The characteristic features of historically formed Food Regime were described in the chronological order, as well as modern tendencies possessing reformist potential were identified. In particular, it has been established that the idea of Food Sovereignty (which is an alternative to the modern Corporate Food Regime is the subject for acute academic disputes. The discussion between P. McMichael P. and H. Bernstein devoted to the “peasant question” — mobilization frame of the Food Sovereignty strategy was analyzed using the secondary data processing method. Due to the critical analysis, the author comes to the conclusion that it is necessary to follow the principles of the Food Sovereignty strategy to prevent the catastrophic prospects associated with ecosystem degradation, accelerated erosion of soils, the complete disappearance of biodiversity and corporate autoc racy successfully. The author is convinced that the idea of Food Sovereignty can ward off energetic liberalization of nature, intensive privatization of life and rapid monetization of unconditioned human reflexes.

This article addresses the potential for food movements to bring about substantive changes to the current global food system. After describing the current corporate food regime, we apply Karl Polanyi's 'double-movement' thesis on capitalism to explain the regime's trends of neoliberalism and reform. Using the global food crisis as a point of departure, we introduce a comparative analytical framework for different political and social trends within the corporate food regime and global food movements, characterizing them as 'Neoliberal', 'Reformist', 'Progressive', and 'Radical', respectively, and describe each trend based on its discourse, model, and key actors, approach to the food crisis, and key documents. After a discussion of class, political permeability, and tensions within the food movements, we suggest that the current food crisis offers opportunities for strategic alliances between Progressive and Radical trends within the food movement. We conclude that while the food crisis has brought a retrenchment of neoliberalization and weak calls for reform, the worldwide growth of food movements directly and indirectly challenge the legitimacy and hegemony of the corporate food regime. Regime change will require sustained pressure from a strong global food movement, built on durable alliances between Progressive and Radical trends.
Protectionism or Legitimate Regulations: What can Trade Partners Expect from the New US Food Safety Regime?

OpenAIRE

Nakuja, T.; Kerr, William A.

2013-01-01

In January 2011, the US passed the Food Safety Modernization Act (FSMA) which represents a major legislative initiative to revise and strengthen the regulatory regime pertaining to foodborne illness and contamination. The tightening of the regulatory regime was justified on the basis of a number of high-profile foodborne disease incidents, which are claimed to have undermined public confidence in the US food safety system. While tightening food safety regulations inevitably increase barriers ...
Node and Regime: Interdisciplinary Analysis of Water-Energy-Food Nexus in the Mekong Region

Directory of Open Access Journals (Sweden)

Tira Foran

2015-02-01

Full Text Available Understanding complex phenomena such as the water-energy-food nexus (resource nexus requires a more holistic, interdisciplinary inquiry. Spurred by a sense of imbalance in approaches to the nexus dominated by integrated assessment/complex systems methodologies, I re-examine the findings and recommendations of a major 'nexus' research-for-development project in the Mekong region. The concept of 'regime of provisioning', a synthesis of social science concepts related to meso-level social order, allows essential political economy and discursive elements of the resource nexus to be analysed. I show that socio-political regimes constrain societal investment in three 'nodes' of the nexus previously identified as critical to manage sustainably: energy efficiency, wild-capture fisheries, and diversified smallholder agriculture. I discuss implications for the 'nexus' as a new policy agenda and offer three propositions for ongoing inquiry and inclusive practice.
The growing disconnect between food prices and wages in Europe: cross-national analysis of food deprivation and welfare regimes in twenty-one EU countries, 2004-2012.

Reeves, Aaron; Loopstra, Rachel; Stuckler, David

2017-06-01

Food insecurity has been rising across Europe following the Great Recession, but to varying degrees across countries and over time. The reasons for this increase are not well understood, nor are what factors might protect people's access to food. Here we test the hypothesis that an emerging gap between food prices and wages can explain increases in reported inability to afford protein-rich foods and whether welfare regimes can mitigate its impact. We collected data in twenty-one countries from 2004 to 2012 using two databases: (i) on food prices and deprivation related to food (denoted by reported inability to afford to eat meat, chicken, fish or a vegetarian equivalent every second day) from EuroStat 2015 edition; and (ii) on wages from the Organisation for Economic Co-operation and Development 2015 edition. After adjusting for macroeconomic factors, we found that each 1 % rise in the price of food over and above wages was associated with greater self-reported food deprivation (β=0·060, 95 % CI 0·030, 0·090), particularly among impoverished groups. However, this association also varied across welfare regimes. In Eastern European welfare regimes, a 1 % rise in the price of food over wages was associated with a 0·076 percentage point rise in food deprivation (95 % CI 0·047, 0·105) while in Social Democratic welfare regimes we found no clear association (P=0·864). Rising prices of food coupled with stagnating wages are a major factor driving food deprivation, especially in deprived groups; however, our evidence indicates that more generous welfare systems can mitigate this impact.
Quality Regimes in Agro-Food Industries

DEFF Research Database (Denmark)

Staricco, Juan Ignacio; Ponte, Stefano

2015-01-01

In this article, we examine the transformative potential of changing quality regimes in agro-food industries through the analysis of whether Fair Trade wine in Argentina provides a meaningful economic alternative that goes beyond the impact it has on direct beneficiaries. The wine sector has a long...... history in valorizing a variety of quality dimensions, and has developed one of the most complex and sophisticated quality infrastructures, making it an ideal terrain of analysis. Furthermore, it is going through a major process of restructuring in which the battle-lines are drawn along the application......, challenge and re-interpretation of different quality content. Through the lenses of a sector-adjusted version of regulation theory, we show that the Fair Trade wine sector does not substantially deviate from the conventional wine economy in Argentina. Instead of empowering the most vulnerable groups, those...
Health claims on foods: challenge for clinical research companies

Directory of Open Access Journals (Sweden)

Essi Sarkkinen

2012-06-01

Full Text Available Background The Nutrition and Health Claim Regulation 1924/2006/EC, together with EFSA guidances on the scientific requirements for different type of health claims, is setting the basis for health claim substantiation in the EU. Aim The aim of this presentation is to bring up the key challenges that the food industry and clinical research organizations are facing when meeting these requirements. Results and discussion Key issues in clinical research planning to meet the requirements set for the health claim substantiation are: (1 Selection of right outcome markers since the selection of outcome marker defines actually the formulation of the health claim to be used on food or food ingredient. (2 Selection of right target population since that determines the target consumer group for the food with a health claim. (3 Selection of dose regime and food matrices used since these largely determine the conditions set for the use of the health claim. One of the major challenges in health claim substantiation is the deviant approach to risk factors or biomarkers. From the regulation point of view, a single risk factor approach is emphasized, but from the clinical and scientific point of view the pattern of different risk markers or biomarkers could, in some cases, be a more relevant choice to reflect the final health outcome. This is especially the case in the nutrition and health area because we are often dealing with weak but multiple health effects of certain food items or ingredients. Also the lack of validated well-established biomarkers potent to be affected by diet is a challenge in health claim substantiation.The selection of right target population is often a compromise between choosing a more potential target group to obtain efficacy (i.e. risk factors elevated vs. patient groups and choosing a rationale to generalize the results to wider population (target consumer group.The selection of optimal dosing regime and matrices for a clinical study is
Intellectual assets management and transfer in food science sector in Indian research and development organizations.

In recent years, the food science sector has gained importance since the society is focusing on high-quality and safety foods. With a specific end goal to meet this societal need, the research and development organizations in India have adopted innovative technical and research processes, which gave more accentuation on intellectual assessment in food processing industry. The global Intellectual Property regime in food science sector had witnessed an increment in the number of patents filed and granted during 2006-2010. Ever since there has been a gradual increase in the number of patents applied mainly in food processing industries by research organizations related to food sciences, for example, those working under the aegis of ICAR and CSIR in India. In this study, a review has been done on the intellectual assets generated by ICAR and other national research organizations in India, in the food science sector. Emphasis has been given on the global relevance of these assets, modes of IP protection and technology transfer mechanisms followed by different public and private organizations.
Regime shift in fertilizer commodities indicates more turbulence ahead for food security.

Directory of Open Access Journals (Sweden)

James J Elser

Full Text Available Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer production on finite non-renewable resources such as mined phosphate- and potassium-bearing rocks. Indeed, recent volatility in food and agricultural commodity prices, especially phosphate fertilizer, has raised concerns about emerging constraints on fertilizer production with consequences for its affordability in the developing world. We examined 30 years of monthly prices of fertilizer commodities (phosphate rock, urea, and potassium for comparison with three food commodities (maize, wheat, and rice and three non-agricultural commodities (gold, nickel, and petroleum. Here we show that all commodity prices, except gold, had significant change points between 2007-2009, but the fertilizer commodities, and especially phosphate rock, showed multiple symptoms of nonlinear critical transitions. In contrast to fertilizers and to rice, maize and wheat prices did not show significant signs of nonlinear dynamics. From these results we infer a recent emergence of a scarcity price in global fertilizer markets, a result signaling a new high price regime for these essential agricultural inputs. Such a regime will challenge on-going efforts to establish global food security but may also prompt fertilizer use practices and nutrient recovery strategies that reduce eutrophication.
Land-use regime shifts: an analytical framework and agenda for future land-use research

Directory of Open Access Journals (Sweden)

Navin Ramankutty

2016-06-01

Full Text Available A key research frontier in global change research lies in understanding processes of land change to inform predictive models of future land states. We believe that significant advances in the field are hampered by limited attention being paid to critical points of change termed land-use regime shifts. We present an analytical framework for understanding land-use regime shifts. We survey historical events of land change and perform in-depth case studies of soy and shrimp development in Latin America to demonstrate the role of preconditions, triggers, and self-reinforcing processes in driving land-use regime shifts. Whereas the land-use literature demonstrates a good understanding of within-regime dynamics, our understanding of the drivers of land-use regime shifts is limited to ex post facto explications. Theoretical and empirical advances are needed to better understand the dynamics and implications of land-use regime shifts. We draw insights from the regime-shifts literature to propose a research agenda for studying land change.

We investigate phase separation and structural evolution in a complex food colloid (casein micelles) and biopolymer (xanthan) mixture using small-angle light scattering. We demonstrate that phase separation is induced by a depletion mechanism, and that the resulting coexistence curve can be described by osmotic equilibrium theory for mixtures of colloids and polymer chains in a background solvent, taking into account interactions between the polymer chains in the excluded volume limit. We show that the light scattering pattern of an unstable mixture exhibits the typical behaviour of spinodal decomposition, and we are able to confirm the validity of dynamic similarity scaling. We find three distinct regimes (initial or linear, intermediate and transition stage) for the decomposition kinetics that differ in the time dependence of the peak position of the structure factor. In particular we find clear evidence for the existence of an initial linear regime, where the peak position remains constant and the amplitude grows. The existence of spinodal-like decomposition and the validity of universal scaling in the intermediate and transition stages have been found in previous studies of phase separation in attractive colloidal suspensions. However, to our knowledge the initial linear regime has never been observed in colloidal suspensions, and we attribute this at least partly to the effect of hydrodynamic interactions which are efficiently screened in our system due to the fact that the measurements were performed at high polymer concentrations, i.e. in the semi-dilute regime.

Obesity under affluence varies by welfare regimes: the effect of fast food, insecurity, and inequality.

Offer, Avner; Pechey, Rachel; Ulijaszek, Stanley

2010-12-01

Among affluent countries, those with market-liberal welfare regimes (which are also English-speaking) tend to have the highest prevalence of obesity. The impact of cheap, accessible high-energy food is often invoked in explanation. An alternative approach is that overeating is a response to stress, and that competition, uncertainty, and inequality make market-liberal societies more stressful. This ecological regression meta-study pools 96 body-weight surveys from 11 countries c. 1994-2004. The fast-food 'shock' impact is found to work most strongly in market-liberal countries. Economic insecurity, measured in several different ways, was almost twice as powerful, while the impact of inequality was weak, and went in the opposite direction. Copyright © 2010 Elsevier B.V.

Kristina Petljak

2011-12-01

Full Text Available This paper presents research findings based on the research conducted on a representative sample of respondents using a highly structured questionnaire. The first part of the paper focuses on the theoretical background and overview of the research results related to the research problem in the world and in Croatia. The results of the research which has been conducted indicate that respondents are not familiar with the definition of organic food. Furthermore, the paper elaborates on the Croatian consumers’ perception of organic food and conventional food. The research on organic food purchase places a special emphasis on regular buyers of organic food who were asked to evaluate the importance of individual characteristics in choosing a place of sale for organic food. Based on the hierarchical regression analysis, the frequency of organic food purchases by regular buyers was found to correlate with the perception of organic food and the importance of characteristics of a place of sale for organic food. The research also identified the main reasons for not buying organic food, and it sets out the guidelines which may be useful to organic producers, marketers and retailers in encouraging further purchases of organic food.
Patterns of serum PCDD/Fs affected by vegetarian regime, consumption of locally produced food, and resident places of residents living near incinerators

Previous reports have been estimated that more than 90% of serum PCDD/Fs can be accounted for by the consumption of various food groups. Nouwen et al. suggested residents living near incinerators with the elevated dioxin exposure while they ate locally produced food compared to the general population from other areas. PCDD/Fs usually abound in fatty meats and marine foods, and consumption of which is the major pathway of human expose to PCDD/Fs. However, no distinct association was shown between vegetarian regime of human and their corresponding serum PCDD/Fs concentration. In addition, the resident region is associated to their corresponding dietary consumption and ambient exposure of PCDD/Fs, especially for subjects consumed the local foods with special dioxin-like contamination. The current study, therefore, was set to examine how dietary habits, including vegetarian regime and consumption of local food original for residents living near the incinerators are associated to serum PCDD/F concentrations. In addition, the further aim is to assess the influence on the serum PCDD/Fs levels resulting from subjects living in the alternative resident regions, even all of them exposed to PCDD/Fs emission from incinerators.
From famine to food crisis: what history can teach us about local and global subsistence crises.

Science.gov (United States)

Vanhaute, Eric

2011-01-01

The number of famine prone regions in the world has been shrinking for centuries. It is currently mainly limited to sub-Saharan Africa. Yet the impact of endemic hunger has not declined and the early twenty-first century seems to be faced with a new threat: global subsistence crises. In this essay I question the concepts of famine and food crisis from different analytical angles: historical and contemporary famine research, food regime theory, and peasant studies. I will argue that only a more integrated historical framework of analysis can surpass dualistic interpretations grounded in Eurocentric modernization paradigms. This article successively debates historical and contemporary famine research, the contemporary food regime and the new global food crisis, the lessons from Europe's 'grand escape' from hunger, and the peasantry and 'depeasantization' as central analytical concepts. Dualistic histories of food and famine have been dominating developmentalist stories for too long. This essay shows how a blending of historical and contemporary famine research, food regime theory and new peasant studies can foster a more integrated perspective.
The FoodCast Research Image Database (FRIDa

2013-03-01

Full Text Available In recent years we have witnessed to an increasing interest in food processing and eating behaviors. This is probably due to several reasons. The biological relevance of food choices, the complexity of the food-rich environment in which we presently live (making food-intake regulation difficult, and the increasing health care cost due to illness associated with food (food hazards, food contamination, and aberrant food-intake. Despite the importance of the issues and the relevance of this research, comprehensive and validated databases of stimuli are rather limited, outdated, or not available for noncommercial purposes to independent researchers who aim at developing their own research program. The FoodCast Research Image Database (FRIDa we present here is comprised of 877 images from eight different categories: natural-food (e.g., strawberry, transformed-food (e.g., French fries, rotten-food (e.g., moldy banana, natural-nonfood items (e.g., pinecone, artificial food-related objects (e.g., teacup, artificial objects (e.g., guitar, animals (e.g., camel, and scenes (e.g., airport.

Going beyond The three worlds of welfare capitalism: regime theory and public health research.

Science.gov (United States)

Bambra, C

2007-12-01

International research on the social determinants of health has increasingly started to integrate a welfare state regimes perspective. Although this is to be welcomed, to date there has been an over-reliance on Esping-Andersen's The three worlds of welfare capitalism typology (1990). This is despite the fact that it has been subjected to extensive criticism and that there are in fact a number of competing welfare state typologies within the comparative social policy literature. The purpose of this paper is to provide public health researchers with an up-to-date overview of the welfare state regime literature so that it can be reflected more accurately in future research. It outlines The three worlds of welfare capitalism typology, and it presents the criticisms it received and an overview of alternative welfare state typologies. It concludes by suggesting new avenues of study in public health that could be explored by drawing upon this broader welfare state regimes literature.

Transforming research for food and health in Europe.

Science.gov (United States)

McCarthy, M

2012-10-01

Eating causes up to a quarter of premature deaths from chronic diseases in Europe through poor diet and excess consumption. FAHRE (Food and Health Research in Europe) was funded to determine needs and gaps in research structures and programmes. Most food research links towards agriculture and the environmental sciences, whereas most health research links towards clinical diseases, biochemical pathways and biology. Research on food and health together includes food safety research addressing biological and chemical contaminants, and biotechnology research supporting clinical nutrition. Research for healthy eating must draw on social and behavioural sciences for studies of policy, regulation and interventions. The food industry, across production, retail and catering, must be part of the research programme, and civil society. Better coordination and improved levels of funding are needed in the coming European research programme 'Horizon 2020', and national programmes linked in the Joint Programming Initiative. Transforming the research agenda can give great benefits to Europe's citizens.
Scenario of research on Food Service in Brazil

Directory of Open Access Journals (Sweden)

Flávia Milagres CAMPOS

Full Text Available ABSTRACT Objective: The present study aims to investigate the scenario of research on Food Service in Brazil based on the Stricto Sensu Graduate Programs in Nutrition, research groups, and scientific production. Methods: A search of the research lines including studies related to this topic and the researchers engaged in those studies was conducted. The research groups were identified on the Directory of Research Groups in Brazil website and the profile of the scientific production was based on articles included in the Scientific Electronic Library Online database. Articles published in international journals that were related to research lines focused on food production were also searched and analyzed. Results: The search identified only two graduate programs with research lines that describe the food production as the object of study although 13 graduate programs carry out research related to Food Service, especially focused on nutritional and sanitary aspects of food. The same trend was observed in the national articles. The internationalization of these two research line results from the academic publication in 22 different journals over the past 5 years. Thirty five professors were identified and most of them hold a PhD in Food Science and Technology. The number of research groups increased from two in 2000 to twenty nine in 2010. Conclusion: The inclusion of Food Service in graduate programs is still limited. The main trend observed is towards a closer relationship with Food Science and Technology in terms of the lines of research, professional qualification, and published studies.

What kind of foods will the consumers choose to buy in 2010? Will they be buying organic foods, functional foods or go for the cheapest products? Nobody can predict the future. However, by using scenario techniques qualified indications on future developments can be put together. Researchers...... at MAPP and the Department of Manufacturing Engineering and Management, The Technical University of Denmark have constructed three scenarios about the Danish food industry in 2010. The aim has been to identify the demands the food industry can expect to meet in the future plus which research areas...... the public research should prioritise in order to support the development of competences within the food industry. The scenarios are isolated developments. In practise, the future is likely to be a combination of the different tendencies within the scenarios. The first scenario 'Naturalness' has focus...
Food security and food insecurity in Europe: An analysis of the academic discourse (1975-2013).

Science.gov (United States)

Borch, Anita; Kjærnes, Unni

2016-08-01

In this paper we address the academic discourse on food insecurity and food security in Europe as expressed in articles published in scientific journals in the period 1975 to 2013. The analysis indicates that little knowledge has been produced on this subject, and that the limited research that has been produced tends to focus on the production of food rather than on people's access to food. The lack of knowledge about European food insecurity is particularly alarming in these times, which are characterised by increasing social inequalities and poverty, as well as shifting policy regimes. More empirical, comparative and longitudinal research is needed to survey the extent of food security problems across European countries over time. There is also a need to identify groups at risk of food insecurity as well as legal, economic, practical, social, and psychological constraints hindering access to appropriate and sufficient food.

Retail food environments research in Canada: A scoping review.

Science.gov (United States)

Minaker, Leia M; Shuh, Alanna; Olstad, Dana L; Engler-Stringer, Rachel; Black, Jennifer L; Mah, Catherine L

2016-06-09

The field of retail food environments research is relatively new in Canada. The objective of this scoping review is to provide an overview of retail food environments research conducted before July 2015 in Canada. Specifically, this review describes research foci and key findings, identifies knowledge gaps and suggests future directions for research. A search of published literature concerning Canadian investigations of retail food environment settings (food stores, restaurants) was conducted in July 2015 using PubMed, Web of Science, Scopus, PsychInfo and ERIC. Studies published in English that reported qualitative or quantitative data on any aspect of the retail food environment were included, as were conceptual papers and commentaries. Eighty-eight studies were included in this review and suggest that the field of retail food environments research is rapidly expanding in Canada. While only 1 paper was published before 2005, 66 papers were published between 2010 and 2015. Canadian food environments research typically assessed either the socio-economic patterning of food environments (n = 28) or associations between retail food environments and diet, anthropometric or health outcomes (n = 33). Other papers profiled methodological research, qualitative studies, intervention research and critical commentaries (n = 27). Key gaps in the current literature include measurement inconsistency among studies and a lack of longitudinal and intervention studies. Retail food environments are a growing topic of research, policy and program development in Canada. Consistent methods (where appropriate), longitudinal and intervention research, and close partnerships between researchers and key stakeholders would greatly advance the field of retail food environments research in Canada.

Full Text Available The paper examines regular flow patterns of high-concentrated limonite pulp with significant content of finest grains. Engineering procedures have been developed to calculate basic parameters of limonite ore hydrotransport in turbulent and structured regimes. Trustworthiness of scientific statements, conclusions and recommendations is justified by theoretical research, establishment of analytical dependences, results of laboratory and industrial experiments. Practical regularities of behavior have been identified for the coefficient of hydraulic resistance, depending on pulp density in the range 35-45 % in case of pulp flow in structured regime, as well as regularity of pressure losses in case of pulp flow in horizontal and inclined pipelines in turbulent regime.

Structuring Tensions and Key Relations of Montreal Seasonal Food Markets in the Sustainability Transition of the Agri-Food Sector

Directory of Open Access Journals (Sweden)

René Audet

2017-02-01

Full Text Available In cities across the world, local food networks aim to make food systems more sustainable and secure for all. As part of that effort, some of these networks also seek to introduce social innovation in the mode of selling food, namely as a way to initiate a broader transition of the sector. Based on two years of action research conducted together with promoters of Montreal’s seasonal markets, this article offers an account of the co-constructed narrative of a transition of the agri-food sector. On the one hand, transition theory anticipates that the transition to sustainability of the agri-food sector would depend on the protection and empowerment of innovative ‘niches’ that are facing the locked-in structure of the agri-food ‘sociotechnical regime’. Yet, on the other hand, the seasonal markets do not fit well in this portrait: they are shown to evolve at the intersection of the sociotechnical regime and innovative niches. For this reason, they are subject to regime rules and become difficult to protect as an entity. As such, seasonal markets face ‘structuring tensions’ that generate both practical dilemmas and innovative solutions in their modes of organization. These solutions, however, rely on webs of resources and supports that constitute ‘key relations’ for unlocking the agri-food regime rules. It is through managing these tensions and relations that the seasonal markets end up reconfiguring social and material relations and providing solutions for food security and a more sustainable food system. Therefore, we argue that the structuring tension and key relation concepts are useful for understanding the dynamics of social innovation in the transition to sustainability in food systems.

Full Text Available Consumer properties of food raw material formed during the heat treatment. New physical, flavoring and aromatic properties of the products of plant origin, formed during drying due to substantial changes in the composition of the raw materia l occurring as a result of biochemical reactions. In the production of dried and roasted products is very important to follow the parameters that contribute to the passage of biochemical processes aimed at creating a product with high nutritional qualities, strong aroma and pleasant taste. We studied the basic kinetics of the drying process of food raw material (in terms of artichoke in a dense interspersed layer, which formed the basis for the rational choice of the drying regime with due consideration of changes in the moisture content of the product are studied. The nature of the effect of the dried product movement hydrodynamic conditions on a layer height and intensity of drying is established. As a result of food raw material drying process kinetics analysis (in terms of artichoke multistep drying regimes were chosen. Analysis of the artichoke particles drying by air, air-steam mixture and superheated steam intensity showed the presence of two parts: the horizontal one and gradually diminishing one. Kinetic laws of the artichoke drying process in a dense interspersed layer were the basis of engineering calculation of dryer with a transporting body in the form of a "traveling wave". Application of the dryer with the transporting body in the form of a "traveling wave" for food raw material drying allow to achieve uniform drying of the product due to the use of soft, gentle regimes of oversleeping while preserving to the utmost particles of the product; to improve the quality of the finished product through the use of interspersed layer that reduces clumping of product to be dried.

Agri-food is very important for human being. Problems in managing agri-food are very complicated. There are many entities involved in managing agri-food with conflict of interest between them makes the problems become more complicated. Using supply chain approaches in agri-food will help solving the problems. The purpose of this paper is to show that the publications in agri-food supply chain research area are still promising and to show the research trend in agri-food supply chain. The study was a bibliometric study by using some queries on the website with the largest database of peer-reviewed literature. The queries were using various categories and refinements. Firstly the study was exploring all publications in this research area in some categories and then divided the duration into 2 intervals. The last query was to know how many publications are review type publications. The results show that the number of the publications with agri-food supply chain topics are still limited, and tend to increase. It means researches in this area are still promising. The results also show the most publications are from which source title, country, and affiliation. The results also show the research trend in this research area. The quantities of review type publications in agri-food supply chain are still few. It shows the need for more review type publications in this area.

Full Text Available In the course of investigations, the structural changes in proteins were established, which were associated with the preliminary treatment of meat ingredients, a pH level of the system and parameters of thermal treatment.The pasteurization regimes allowed retaining a protein nitrogen proportion up to 94% by the end of canned food storage duration. Upon sterilization, the losses in protein nitrogen were two times higher. A negative eﬀect of more acidic sauce on preservation of the protein nitrogen fraction in canned foods was established.An accumulation of the peptide nitrogen fraction in the canned foods in tomato sauce aﬅer pasteurization was two times more intensive. In the sterilized canned foods, the processes of accumulation of the low molecular weight nitrogenous compounds were more intensive, which suggests a depth of destruction of the protein and peptide nitrogen fraction. It was shown that an accumulation of amino-ammonia nitrogen during canned food storage was on average 12.4% irrespective of the pH value in the used sauces and the type of thermal treatment.A shiﬅ in the pH value of the canned foods toward the acid side upon pasteurization was noticed. With that, a degree of the shiﬅ in the canned foods in tomato sauce was 2.5 times higher than the pH value of the canned foods in sour cream sauce. When sterilizing canned foods, another dynamics of the pH values was observed: a pH value declined by 0.39 units in the canned foods in tomato sauce and grew by 0.22 units in the canned foods in sour cream sauce. During storage, the tendency of more intense pH decline was revealed for the canned foods in tomato sauce aﬅer pasteurization compared to the canned foods aﬅer sterilization. Another character of the pH value dynamics was found in the canned foods in sour cream sauce: an insigniﬁcant increase (by 0.7% of the pH value in the pasteurized canned foods and a signiﬁcant decrease (by 8.4% in the sterilized canned foods

Food allergy is a significant health issue in the UK, affecting between 1 and 2% of adults and 5 and 8% of children. The UK Food Standards Agency seeks to ensure the safety of food allergic consumers by providing them with information and guidance on food choices. Since 1995, with the aim of addressing important policy issues and improving the quality of the support and guidance available for food allergic consumers, the Agency (and before that the Ministry of Agriculture, Fisheries and Food), has had a programme of research dedicated to investigating the causes and mechanisms of food allergy and delivering benefits for UK consumers. In this paper, we outline some of the major scientific challenges that the programme has sought to address. We reflect on how the findings have been used as a basis for the development of sound, evidence-based policy and advice for UK consumers, and the current direction of research being supported by the programme.
Using a research framework to identify knowledge gaps in research on food marketing to children in Australia.

Chapman, Kathy; Kelly, Bridget; King, Lesley

2009-06-01

Research in the field of food marketing to children requires a better understanding of the research gaps in order to inform policy development. The purpose of this paper was to propose a framework for classifying food marketing research, using Australian research on food marketing to children to demonstrate how this framework can be used to determine knowledge gaps. A literature review of research databases and 'grey' material was conducted to identify research from the previous 10 years. Studies were classified according to their research focus, and media type, as either: exposure, including content analyses; effects of exposure, including opinions, attitudes and actions resulting from food marketing exposure; regulations, including the type and level of regulation that applies to food marketing; or breaches of regulations, including instances where marketing regulations have been violated. The majority of Australian research on food marketing to children has focused on television advertising and exposure research. Research has consistently shown that the content of food marketing directed at children is predominately for unhealthy foods. There is a lack of research on the effects of food marketing, which would be valuable to inform policy. The development of a logical framework for food marketing research allows for the identification of research gaps and enables research priorities to be identified.

Abstract Background Diet, in addition to tobacco, alcohol and physical exercise, is a major factor contributing to chronic diseases in Europe. There is a pressing need for multidisciplinary research to promote healthier food choices and better diets. Food and Health Research in Europe (FAHRE) is a collaborative project commissioned by the European Union. Among its tasks is the description of national research systems for food and health and, in work reported here, the identification of strengths and gaps in the European research base. Methods A typology of nine research themes was developed, spanning food, society, health and research structures. Experts were selected through the FAHRE partners, with balance for individual characteristics, and reported using a standardised template. Results Countries usually commission research on food, and on health, separately: few countries have combined research strategies or programmes. Food and health are also strongly independent fields within the European Commission\\'s research programmes.

Do Local Food Networks Foster Socio-Ecological Transitions towards Food Sovereignty? Learning from Real Place Experiences

Directory of Open Access Journals (Sweden)

Juliana Lutz

2013-11-01

Full Text Available Drawing on transition theory, we conceptualize local food networks as innovations that initially function and develop in local niches within a given food regime. As niche-innovations local food networks induce socio-ecological changes on the local level and they have the potential to foster wider transformations of the dominant food regime. Many local food networks adopt the concept of food sovereignty as a kind of “leitmotif”. At the core of this concept lies the question of how to create an agro-food system that, (i allows for democratic participation and civic engagement in food production, and (ii sets up new relationships that avoid social inequity and the exploitation of both humans and nature. In this paper we shed light on how the Austrian local food network “SpeiseLokal” addresses the challenge of operationalizing the concept of food sovereignty. The case study captures the strategies which local food networks embark on and depicts the difficulties they encounter. The paper aims to identify critical points of intersection that either strengthen or constrain local food networks from becoming established, operating, and up-scaling in the ways they wish; that is, in accordance with the principles and aims of food sovereignty, while avoiding a later assimilation into the dominant food regime.
Resilience in the Romanian Food Industry. Preliminary Research

Silvius STANCIU

2015-12-01

Full Text Available Critical situations occurring in the food chain represent a cause for concern for companies, consumers and government authorities. Food product supply continuity assurance is supported by economic considerations coming from producers or food product merchants, by the increasing demand that exists on the market or by the political implications regarding food security assurance among the population. The study focuses on assessing the extent to which the food sector economic agents are prepared to face potential critical situations in the unfolding of their business activities. In Romania there haven’t been carried out any studies regarding food chain resilience regarding critical incidents and the economic impact of these incidents on the food sector. The main objective of the research was the Romanian food chain resilience assessment to critical situations, having a highly applicative character. It was based on questionnaires given to a representative sample of companies and it highlighted the food companies’ resilience to critical situations. The responding economic agents were mainly from the agro-food production, food distribution, food production and distribution, and other related domains. The research regarding food chain resilience to critical situations in Romania showed a primary character of the concept; therefore, this sector must be developed both at a strategic and operational level.

2014-01-01

Full Text Available The article presents the results of the research of organic food frequency of consumption (in general, conducted in Serbia in June 2013 (n=300. Respondents were classified into low-frequent organic food consumers' segment and high-frequent organic food consumers' segment. Socio-demographic characteristics of respondents were also investigated, thus allowing comparing two segments regarding consumers' profile. The organic food high-frequent consumers' segment consisted of more women, more educated people, more married respondents and respondents living with children and having larger households, as well as of consumers with higher self-assessed household income in comparison to organic food low-frequent consumers' segment. Having in mind the results of the research and the level of domestic market development when choosing which segment to target, as well as starting from understanding promotion in the context of integrated marketing communication and the means-end approach to consumer behavior, recommendations for organic food promotion were given.

As the living standard rises, people are more concerned with the health benefits of foods. Functional foods are, therefore, receiving increasing attention worldwide. The functional food market in Taiwan reached 1.78 billion US dollars in 2005. Only those which have been certified by the Department of Health can claim their health benefits. Until January 2007, only 88 functional foods have received the certificates. In addition to the product development in the food industry, research institutes and universities are also actively engaged in the technology development and basic research of functional foods. Many raw materials harvested in Taiwan, including edible plants, herbs, medicinal mushrooms, and sea foods, are investigated for their health benefits, bioactive components and suitable processing technologies.

Trade and commerce in improved crops and food: an essay on food security.

Science.gov (United States)

Kershen, Drew L

2010-11-30

Agricultural trade between nations is a significant proportion of total international trade. Agricultural trade in transgenic crops faces extra complications due to the existence of domestic and international regimes that focus specifically on agricultural biotechnology. These specialized regimes create legal and commercial challenges for trade in transgenic crops that have significant implications for the food security of the nations of the world. By food security, one should understand not just the available supply of food, but also the quality of the food and the environmental impact of agricultural production systems. These specialized regimes for transgenic crops can either encourage or hinder the adoption of agricultural biotechnology as a sustainable intensive agriculture. Sustainable intensive agriculture offers hope for agronomic improvements for agricultural production, socio-economic betterment for farmers and environmental benefits for societies. Sustainable intensive agriculture offers particular hope for the poorest farmers of the world because agricultural biotechnology is a technology in the seed. Copyright © 2010 Elsevier B.V.

The paper reviews current research in Egypt in the field of radiation preservation of food to accumulate the necessary data for drafting Egypts' policy towards prospects for application. Research activities in Egypt have been oriented to solving problems of local economic importance, e.g. inhibition of sprouting in potatoes, onions and garlic, extension of shelf-life of vegetables and fruits, disinfestation of stored grains and grain products, preservation of meat, meat products, fish, fats and oils, and elimination of parasites and microorganisms from animal feed. Extensive studies have been performed to determine the lowest radiation level required for short-term storage, changes in organoleptic, physical, chemical and microbiological values of irradiated food and wholesomeness studies to give evidence of the safety of irradiated food for human consumption. The paper summarizes Egypt's national planning for the transfer of such new technology, the establishment of the National Centre for Radiation Research and Technology to build up the national infrastructure for food irradiation research and application, and the formation of a Supreme Committee for Radiation Preservation of Food. Finally, the paper also surveys the locally available irradiators and correlates the design, capacity and capital cost against the actual needs of Egypt and the experience acquired. (author)

Transition from weak wave turbulence regime to solitonic regime

Science.gov (United States)

Hassani, Roumaissa; Mordant, Nicolas

2017-11-01

The Weak Turbulence Theory (WTT) is a statistical theory describing the interaction of a large ensemble of random waves characterized by very different length scales. For both weak non-linearity and weak dispersion a different regime is predicted where solitons propagate while keeping their shape unchanged. The question under investigation here is which regime between weak turbulence or soliton gas does the system choose ? We report an experimental investigation of wave turbulence at the surface of finite depth water in the gravity-capillary range. We tune the wave dispersion and the level of nonlinearity by modifying the depth of water and the forcing respectively. We use space-time resolved profilometry to reconstruct the deformed surface of water. When decreasing the water depth, we observe a drastic transition between weak turbulence at the weakest forcing and a solitonic regime at stronger forcing. We characterize the transition between both states by studying their Fourier Spectra. We also study the efficiency of energy transfer in the weak turbulence regime. We report a loss of efficiency of angular transfer as the dispersion of the wave is reduced until the system bifurcates into the solitonic regime. This project has recieved funding from the European Research Council (ERC, Grant Agreement No. 647018-WATU).
Experimental research on the relation between food price changes and food-purchasing patterns: a targeted review.

Epstein, Leonard H; Jankowiak, Noelle; Nederkoorn, Chantal; Raynor, Hollie A; French, Simone A; Finkelstein, Eric

2012-04-01

One way in which to modify food purchases is to change prices through tax policy, subsidy policy, or both. We reviewed the growing body of experimental research conducted in the laboratory and in the field that investigates the following: the extent to which price changes influence purchases of targeted and nontargeted foods, total energy, or macronutrients purchased; the interaction of price changes with adjunctive interventions; and moderators of sensitivity to price changes. After a brief overview of economic principles and observational research that addresses these issues, we present a targeted review of experimental research. Experimental research suggests that price changes modify purchases of targeted foods, but research on the overall nutritional quality of purchases is mixed because of substitution effects. There is mixed support for combining price changes with adjunctive interventions, and there are no replicated findings on moderators to price sensitivity in experiments. Additional focused research is needed to better inform food policy development with the aim of improving eating behavior and preventing obesity.

Minimising food waste: a call for multidisciplinary research.

Science.gov (United States)

Alamar, Maria Del Carmen; Falagán, Natalia; Aktas, Emel; Terry, Leon A

2018-01-01

Food losses and waste have always been a significant global problem for mankind, and one which has become increasingly recognised as such by policy makers, food producers, processors, retailers, and consumers. It is, however, an emotive subject whereby the extent, accuracy and resolution of available data on postharvest loss and waste are questionable, such that key performance indicators on waste can be misinformed. The nature and extent of food waste differ among developed economies, economies in transition and developing countries. While most emphasis has been put on increasing future crop production, far less resource has been and is still channelled towards enabling both established and innovative food preservation technologies to reduce food waste while maintaining safety and quality. Reducing food loss and waste is a more tractable problem than increasing production in the short to medium term, as its solution is not directly limited, for instance, by available land and water resources. Here we argue the need for a paradigm shift of current funding strategies and research programmes that will encourage the development, implementation and translation of collective biological, engineering and management solutions to better preserve and utilise food. Such multidisciplinary thinking across global supply chains is an essential element in the pursuit of achieving sustainable food and nutritional security. The implementation of allied technological and management solutions is reliant on there being sufficient skilled human capital and resources. There is currently a lack of robust postharvest research networks outside of the developed world, and insufficient global funding mechanisms that can support such interdisciplinary collaborations. There is, thus, a collective need for schemes that encourage inter-supply chain research, knowledge exchange and capacity building to reduce food losses and waste. © 2017 Society of Chemical Industry. © 2017 Society of Chemical

Evaluating North Carolina Food Pantry Food Safety-Related Operating Procedures.

Science.gov (United States)

Chaifetz, Ashley; Chapman, Benjamin

2015-11-01

Almost one in seven American households were food insecure in 2012, experiencing difficulty in providing enough food for all family members due to a lack of resources. Food pantries assist a food-insecure population through emergency food provision, but there is a paucity of information on the food safety-related operating procedures used in the pantries. Food pantries operate in a variable regulatory landscape; in some jurisdictions, they are treated equivalent to restaurants, while in others, they operate outside of inspection regimes. By using a mixed methods approach to catalog the standard operating procedures related to food in 105 food pantries from 12 North Carolina counties, we evaluated their potential impact on food safety. Data collected through interviews with pantry managers were supplemented with observed food safety practices scored against a modified version of the North Carolina Food Establishment Inspection Report. Pantries partnered with organized food bank networks were compared with those that operated independently. In this exploratory research, additional comparisons were examined for pantries in metropolitan areas versus nonmetropolitan areas and pantries with managers who had received food safety training versus managers who had not. The results provide a snapshot of how North Carolina food pantries operate and document risk mitigation strategies for foodborne illness for the vulnerable populations they serve. Data analysis reveals gaps in food safety knowledge and practice, indicating that pantries would benefit from more effective food safety training, especially focusing on formalizing risk management strategies. In addition, new tools, procedures, or policy interventions might improve information actualization by food pantry personnel.
[Food industry funding and epidemiologic research in public health nutrition].

The interests of the food industry to fund nutrition and health research are not limited to promoting scientific advances. Recently, several systematic reviews conducted about the effect of sugar-sweetened beverages and health outcomes have shown some biased conclusions in studies that acknowledge industry sponsorship. In this context, the Nutrition Working Group of the Spanish Epidemiology Society presented a scientific session entitled Food industry and epidemiologic research at its annual meeting. In a round table, four experts in nutrition research presented their points of view about whether the food industry should fund nutrition-related research and the related potential conflicts of interest of the food industry. All the experts agreed not only on defending independence in nutritional epidemiology regarding the design, interpretation and conclusion of their studies but also on the crucial need for guaranteed scientific rigor, scientific quality of the results and measures to protect studies against potential biases related to the conflicts of interest of funding by the food industry. Drs Pérez-Farinós and Romaguera believe that the most effective way to prevent conflicts of interest would be not to allow the food industry to fund nutrition research; Drs Marcos and Martínez-González suggested the need to establish mechanisms and strategies to prevent the potential influences of the food industry in selecting researchers or institutional sponsorship and in the analysis and results of the studies, to ensure maximum independence for researchers, as well as their professional ethics.

The first part of the report presented the results of wholesomeness evaluation of the irradiated potato, onion, rice and wheat by Organization of the National Research Programme on Food Irradiation which conducts food irradiation in Japan. The second part dealt with the wholesomeness evaluation of food irradiation by the joint specialist conference of FAO, IAEA and WHO. It was concluded that irradiation of a maximum mean of 10 KGy or less was unconditionally permissible for every food item, not requiring a toxicity test. However, the relationship between irradiation techniques and economic feasibility, wholesomeness of high dose irradiation, the human effect of use of irradiated food item, food chemistry and nutritional problems remain to be examined.

One way in which to modify food purchases is to change prices through tax policy, subsidy policy, or both. We reviewed the growing body of experimental research conducted in the laboratory and in the field that investigates the following: the extent to which price changes influence purchases of targeted and nontargeted foods, total energy, or macronutrients purchased; the interaction of price changes with adjunctive interventions; and moderators of sensitivity to price changes. After a brief overview of economic principles and observational research that addresses these issues, we present a targeted review of experimental research. Experimental research suggests that price changes modify purchases of targeted foods, but research on the overall nutritional quality of purchases is mixed because of substitution effects. There is mixed support for combining price changes with adjunctive interventions, and there are no replicated findings on moderators to price sensitivity in experiments. Additional focused research is needed to better inform food policy development with the aim of improving eating behavior and preventing obesity. PMID:22378726

The USDA food and nutrient databases provide the basic infrastructure for food and nutrition research, nutrition monitoring, policy, and dietary practice. They have had a long history that goes back to 1892 and are unique, as they are the only databases available in the public domain that perform these functions. There are 4 major food and nutrient databases released by the Beltsville Human Nutrition Research Center (BHNRC), part of the USDA's Agricultural Research Service. These include the USDA National Nutrient Database for Standard Reference, the Dietary Supplement Ingredient Database, the Food and Nutrient Database for Dietary Studies, and the USDA Food Patterns Equivalents Database. The users of the databases are diverse and include federal agencies, the food industry, health professionals, restaurants, software application developers, academia and research organizations, international organizations, and foreign governments, among others. Many of these users have partnered with BHNRC to leverage funds and/or scientific expertise to work toward common goals. The use of the databases has increased tremendously in the past few years, especially the breadth of uses. These new uses of the data are bound to increase with the increased availability of technology and public health emphasis on diet-related measures such as sodium and energy reduction. Hence, continued improvement of the databases is important, so that they can better address these challenges and provide reliable and accurate data.

Mobile food vendors (also known as street food vendors) may be important sources of food, particularly in minority and low-income communities. Unfortunately, there are no good data sources on where, when, or what vendors sell. The lack of a published assessment method may contribute to the relative exclusion of mobile food vendors from existing food-environment research. A goal of this study was to develop, pilot, and refine a method to assess mobile food vendors. Cross-sectional assessment of mobile food vendors through direct observations and brief interviews. Using printed maps, investigators canvassed all streets in Bronx County, NY (excluding highways but including entrance and exit ramps) in 2010, looking for mobile food vendors. For each vendor identified, researchers recorded a unique identifier, the vendor's location, and direct observations. Investigators also recorded vendors answers to where, when, and what they sold. Of 372 identified vendors, 38% did not answer brief-interview questions (19% were 'in transit', 15% refused; others were absent from their carts/trucks/stands or with customers). About 7% of vendors who ultimately answered questions were reluctant to engage with researchers. Some vendors expressed concerns about regulatory authority; only 34% of vendors had visible permits or licenses and many vendors had improvised illegitimate-appearing set-ups. The majority of vendors (75% of those responding) felt most comfortable speaking Spanish; 5% preferred other non-English languages. Nearly a third of vendors changed selling locations (streets, neighbourhoods, boroughs) day-to-day or even within a given day. There was considerable variability in times (hours, days, months) in which vendors reported doing business; for 86% of vendors, weather was a deciding factor. Mobile food vendors have a variable and fluid presence in an urban environment. Variability in hours and locations, having most comfort with languages other than English, and reluctance

In China, there is an old saying:food is the first necessity of humans. The main concern of the Chinese used to be the security of the food supply rather than the safety of the food itself. However,after a long time fighting food shortages,China became self-sufficient in food in 1995. At this time, the country began for the first time to regulate food safety. Yet China has still not established a legal systern efficient in ensuring this safety. Many problems are rooted in the administration regime and China's priority of economic development.

"Research Issues: The Food Environment and Obesity" is an article series commissioned by the American Society for Nutrition and The Obesity Society in an attempt to consider the state of understanding on this topic and identify key knowledge gaps. Roberts and Karl focus on the role of energy density in the regulation of energy intake and body weight and offer recommendations for prioritizing research. Finkelstein et al examine food and beverage purchases as a function of price changes and conclude that targeted food taxes and subsidies alone are unlikely to substantially affect obesity. Pereira points out the difficulty in establishing the strength of the association between intake of sugar-sweetened beverages and weight gain and obesity. Johnson and Wardle review the effects of palatability and variety on eating behavior and weight. Livingstone and Pourshahidi examine the impact of portion size manipulations on energy intake and weight management and find that consumers generally tend to eat proportionally more as portion size increases. Kant focuses on the efficacy and effectiveness of eating frequency manipulation for body weight management and finds that such manipulation has consistently yielded null results. Finally, Gordon-Larsen identifies several limitations of the existing literature regarding neighborhood access to healthy foods. © 2014 American Society for Nutrition.
Ecosystem regime shifts disrupt trophic structure.

Regime shifts between alternative stable ecosystem states are becoming commonplace due to the combined effects of local stressors and global climate change. Alternative states are characterized as substantially different in form and function from pre-disturbance states, disrupting the delivery of ecosystem services and functions. On coral reefs, regime shifts are typically characterized by a change in the benthic composition from coral to macroalgal dominance. Such fundamental shifts in the benthos are anticipated to impact associated fish communities that are reliant on the reef for food and shelter, yet there is limited understanding of how regime shifts propagate through the fish community over time, relative to initial or recovery conditions. This study addresses this knowledge gap using long-term data of coral reef regime shifts and recovery on Seychelles reefs following the 1998 mass bleaching event. It shows how trophic structure of the reef fish community becomes increasingly dissimilar between alternative reef ecosystem states (regime-shifted vs. recovering) with time since disturbance. Regime-shifted reefs developed a concave trophic structure, with increased biomass in base trophic levels as herbivorous species benefitted from increased algal resources. Mid trophic level species, including specialists such as corallivores, declined with loss of coral habitat, while biomass was retained in upper trophic levels by large-bodied, generalist invertivores. Recovering reefs also experienced an initial decline in mid trophic level biomass, but moved toward a bottom-heavy pyramid shape, with a wide range of feeding groups (e.g., planktivores, corallivores, omnivores) represented at mid trophic levels. Given the importance of coral reef fishes in maintaining the ecological function of coral reef ecosystems and their associated fisheries, understanding the effects of regime shifts on these communities is essential to inform decisions that enhance ecological
A two-phase flow regime map for a MAPLE-type nuclear research reactor fuel channel: Effect of hexagonal finned bundle

Harvel, G.D.; Chang, J.S.

1997-01-01

A two-phase flow regime map is developed experimentally and theoretically for a vertical hexagonal flow channel with and without a 36-finned rod hexagonal bundle. This type of flow channel is of interest to MAPLE-type nuclear research reactors. The flow regime maps are determined by visual observations and observation of waveforms shown by a capacitance-type void fraction meter. The experimental results show that the inclusion of the finned hexagonal bundle shifts the flow regime transition boundaries toward higher water flow rates. Existing flow regime maps based on pipe flow require slight modifications when applied to the hexagonal flow channel with and without a MAPLE-type finned hexagonal bundle. The proposed theoretical model agrees well with experimental results

Studies on various aspects of food irradiation have been done in Indonesia since 1968, mainly at the Centre for the Application of Isotopes and Radiation, National Atomic Energy Agency of Indonesia. Three irradiation facilities available at the Centre are gamma cell-220, panoramic batch irradiator, and latex irradiator with the present source capacities of about 1.1, 40, and 163.8 kCi Co-60, respectively. In this paper, the present status of research and development on irradiation is presented, covering (1) spices and medicinal plants, (2) rice, wheat flour and coffee bean, (3) fish and fishery products, (4) animal feed, and (5) ongoing projects including fresh fruits, cacao beans, and cashew nut. The Sub-Committee for the Control of Irradiation of Food and Medical Products, set up in August 1984, has prepared the draft of recommendations regarding the regulation for application of food irradiation in Indonedia and the draft of Regulation for the Control of and Trade in Irradiated Food and Traditional Drug to be issued by the government.

While past research has emphasized the importance of international regimes for international governance, systematic assessments of regime effects are missing. This article derives a standardized measurement concept for the effectiveness of international environmental regimes by developing an operational rational choice calculus to evaluate actual policy simultaneously against a non-regime counterfactual and a collective optimum. Subsequently, the empirical feasibility of the measurement instrument is demonstrated by way of two international treaties regulating transboundary air pollution in Europe. The results demonstrate that the regimes indeed show positive effects - but fall substantially short of the collective optima. (orig.)

Since 1987 and following the accident on Tchernobyl nuclear plant, regulations and monitoring-control programmes have been implemented by MAPP, mainly based on Cs 134 and 137 and Sr 90 researches in raw products such as game, milk and dairy products and honey A new monitoring and control programme has been implemented as from 2009, with the help of IRSN and thanks to the work on management during post-accidental phases initiated in 2005 by ASN. Mainly the activity of Cs is determined but also other parameters are measured such as Ca, K and l 131 activities in the samples analysed by IRSN. In 2009, 812 samples were programmed and all of them have proven to be conform. During the year 2010, 725 samples will be collected, Global exposure to radioactivity in France is estimated at 4000 μSv per year, food and water contributing to 6% (that is about 250 μSv) mainly due to K and Ca (natural radioactive components of the regime).

Full Text Available This paper describes the theoretical and conceptual framework and the research and practice model of Think&EatGreen@School, a community-based action research project aiming to foster food citizenship in the City of Vancouver and to develop a model of sustainable institutional food systems in public schools. The authors argue that educational and policy interventions at the school and school board level can drive the goals of food system sustainability, food security, and food sovereignty. The complex relationship between food systems, climate change and environmental degradation require that international initiatives promoting sustainability be vigorously complemented by local multi-stakeholder efforts to preserve or restore the capacity to produce food in a durable manner. As a step towards making the City of Vancouver green, we are currently involved in attempts to transform the food system of the local schools by mobilizing the energy of a transdisciplinary research team of twelve university researchers, over 300 undergraduate and graduate students, and twenty community-based researchers and organizations working on food, public health, environmental and sustainability education.

The Research of Food Preservation by Irradiation and Its Industrialization in Korea

International Nuclear Information System (INIS)

Cho, Han Ok

1987-01-01

Since the late 1960s, radiation effects on the storage of potatoes, strawberry, grapes and rice have been investigated on an experimental basis in Korea, Based on the research results of batch scale storage for sprouting food (potatoes, onions, chestnuts) and white ginseng powder by the Korea Advanced Energy Research Institute (KAERI) and on the recommendation. Food irradiation is a new process that may provide an alternative to existing food processes. From the extensive research in food irradiation for more than three decades by leading international organizations and advanced countries, the efficacy of a number of applications has been established, including sprout inhibition, disinfestation of insects, sterilization, delay of ripening, and improvement of organoleptic properties in food. Owing to the recommendation on the Wholesomeness of Irradiated Food by the Joint FAO/IAEA/W/o Expert Committee in 1980 and the adaption of the Codex General Standard for Irradiated Food by the Codex Allurements Commission in 1983, as of May 1985, thirty-two countries have officially approved 227 food items in 73 food groups as safe for human consumption. Food irradiation processing is increasingly recognized as a viable technology for reducing the overall quantity of spoiled food, reducing energy used in food storage, and reducing reliance on chemicals currently used
Modelling of void formation in the subcooled boiling regime in the ATHLET code to simulate flow instability for research reactors

International Nuclear Information System (INIS)

Hainoun, A.

1996-01-01

The ATHLET thermohydraulic code was developed at the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS, Society for Plant and Reactor Safety) to analyse leaks and transients for power reactors. In order to extend the code's range of application to the safety analysis of research reactors, a model was implemented permitting a description of the thermodynamic non-equilibrium effects in the subcooled boiling regime. The aim of the extension is, on one hand, to cover the thermohydraulic instability which is particularly characteristic of research reactors owing to their high power densities and low system pressures and, on the other hand, to provide a consideration of the influence of the steam formed in this boiling regime on the neutron balance. The model developed takes into consideration the competing evaporation and condensation effects in the subcooled boiling regime. It describes the bubble production rate at the superheated heating surfaces as well as the subsequent condensation of the bubbles in the subcooled core flow. The installed model is validated by the recalculation of two extensive series of experiments. In the first series the McMaster experiments on axial void distribution in the subcooled boiling regime are recalculated. The recalculation shows that the extended programme is capable of calculating the axial void distribution in the subcooled boiling regime with good agreement with the data. The second series deals with KFA experiments on thermohydraulic instability (flow excursion) in the subcooled boiling regime, comprising a broad parameter range of heat flow density, inlet temperature and channel width. Recalculation of this experimental series shows that the programme extension ensures simulation of thermohydraulic instability. (orig.)
Genetically Modified Food Labeling in China: In Pursuit of a Rational Path.

Zhu, Xiao; Roberts, Michael T; Wu, Kaijie

2016-08-01

Facing a tension between the increasing use of genetically engineered or modified food and consumer concerns over the risks associated with GMOs, China has established a GM food labeling regime through regulations-known as Agro-GMO regulations-to protect consumers' right to know. However, the design and enforcement of this GM food labeling regime is problematic. As a result, the labeling regime is ineffective and inconsistent, leaving consumers' rights unprotected. As the recently amended Food Safety Law in China requires GM food labeling for the first time, this article argues that China should replace the current Agro-GMO food labeling scheme with a special regulatory scheme. A comparative analysis of the GM food labeling systems in the European Union and United States, coupled with a rigorous examination of the problems and barriers of GM food labeling in China, sets a solid foundation by which to propose changes to incorporate into a special regulatory scheme. To this end, this article engages in such an analysis and recommends practical steps to guide the enactment of a special regulatory scheme. The recommendations comport with China's unique legal and political culture, but also could be used by other national regulatory regimes who permit use of GM food while also being committed to improving consumers' right to know.

Since 1987, successive framework programmes have contributed to strengthen European food research through the establishment of networks between research institutions, universities and companies from various European countries. In the FAIR programme (1994-1998), 118 research projects comprising nearly 1,000 participants from the European Union and Associated States have been supported in the food area with a European funding of about [symbol: see text] 108 million. Within the Quality of Life and Management of Living Resources programme (1998-2002), food research is mostly supported within the key action 'food, nutrition and health' with a budget of [symbol: see text] 290 million. After the first four deadlines, 735 eligible research proposals have already been received. Further to their evaluation by a panel of independent experts, 108 proposals have been funded or selected for funding representing a total contribution of about [symbol: see text] 168 million. Among those, several clusters of projects are now running on important topics such as probiotics, coeliac diseases, mycotoxins, GMO, safety and food for the elderly. In addition, technology stimulation measures are largely benefiting SMEs to foster their innovation potential. In January 2000, the European Commission adopted a Communication entitled "Towards the European Research Area (ERA)" with the objective to contribute to developing better framework conditions for research in Europe. On 21 February 2001, the Commission adopted proposals to be submitted to the European Parliament and Council for the next framework programme for research and innovation (2002-2006). The new framework programme that is becoming one of the financial instruments of the ERA aims at catalysing the integration of European research by: strengthening of links between the Community research effort and national and regional research policies; concentrating on a limited number of priority fields or research to which activities at the

As members of the scientific committee for the Food Environments in Canada conference, we reflect on the current state of food environments research in Canada. We are very encouraged that the field is growing and there have been many collaborative efforts to link researchers in Canada, including the 2015 Food Environments in Canada Symposium and Workshop. We believe there are 5 key challenges the field will need to collectively address: theory and causality; replication and extension; consideration of rural, northern and vulnerable populations; policy analysis; and intervention research. In addressing the challenges, we look forward to working together to conduct more sophisticated, complex and community-driven food environments research in the future.

Feeding trials in organic food quality and health research

DEFF Research Database (Denmark)

Velimirov, Alberta; Huber, Machteld; Lauridsen, Charlotte

2010-01-01

Feeding experiments comparing organically and conventionally produced food are performed to assess the overall impact on the animals' health as a model for the effects experienced by the human consumers. These experiments are based on systems research and characterized by their focus on production...... research is not just about simple cause-effect chains, but rather about the pluralism of interactions in biological networks; therefore, the interpretation of the outcome of whole food experiments is difficult. Furthermore, the test diets of organic and conventional origin can be constituted in different...... methods, whole food testing and procedures in accordance with the terms of organic farming. A short review of such experiments shows that the majority of these tests revealed effects of the organically produced feed on health parameters such as reproductive performance and immune responses.

Blackburn, C.M.; Holley, P.A.; Pryke, D.C.

1993-01-01

In their 1986 report on the safety and wholesomeness of irradiated food the UK Advisory Committee on Irradiated and Novel Foods (ACINF) recognised that a generally applicable test to determine if a food had been irradiated was not available. The committee considered that, although not a pre-requisite, the existence of a detection test would be a useful supplement to a control system and do much to reassure consumers; with this in mind ACINF recommended that detection methods should be kept under review. As a consequence, in 1987 the Ministry initiated a comprehensive R and D detection test programme. Over fifty papers have been published to date as a result of this programme. MAFF (Ministry Of Agriculture Fisheries and Food) has also been involved in other research associated with irradiation and food safety, some of which is described in this paper. This paper aims to give an overview of recent work funded under the food irradiation programme. Twelve projects have been supported over the last two years, ten of which involved the development of detection tests for irradiated food. A summary of these projects is presented: - Thermoluminescence; - Electron Spin Resonance; - 2-alkylcyclobutanones; -Determination Of Hydrogen; - Differential Scanning Calorimetry; - Limulus Amoebocyte Lysate; - DNA; - Pesticide Breakdown; - Neutron Irradiation; -Future Plans.

De Facto Regimes in International Law

Directory of Open Access Journals (Sweden)

Jonte van Essen

2012-02-01

Full Text Available The ambiguous position of de facto regimes in international law has long been the subject of scholarly debate and a source of political conflict. An assessment of the current standing of these regimes in international law and the consequences of actions by international actors on this status has, however, been long overdue. The manner in which de facto regimes are regarded internationally has serious consequences for the individuals under the influence of this legal grey area. Therefore, the study into this problem and possible solutions is of great significance. The 2011 developments in Northern Africa underline the need of contemporary research into this area. This essay aims to clarify the position of de facto regimes in international law and the influence on their status by actions of international actors. The author first argues that de facto regimes have rights and obligations under international law, which provide them with (some form of international legal personality. He then pleads for a reconsideration of the contemporary legal treatment of these regimes. The author argues against the current system of government recognition and proposes a system that better addresses the needs of both de facto regimes and the international community.
Impact of Research on Development in Cameroon: convergence between supply and research needs in the food sector

Energy Technology Data Exchange (ETDEWEB)

Minkoua, J.R.; Temple, L.

2016-07-01

The study analyse the convergence of research priorities to development issues especially from the agricultural and food sector in terms of environmental protection and improvement of the business climate, due to weak institutional interconnection devices. Two types of data are used: bibliometric data and a survey of enterprises. Altogether, 1214 and 1708 bibliographic references were generated from WoS and Scopus respectively (from a total of 9146 and 10 557 publications) in Agriculture, Food and Environment for the period 1991- 2015 subject to the condition that the author or at least one of the authors is affiliated to an institution based in Cameroon. A total of 317 agro-food companies were identified from the National Institute enterprise’s census. The overall message is a relative weak convergence between development priorities identified from perceptions over agricultural and food companies and research works expressed in the scientific literature. This reflects the weak link between research institutions (universities, research centers) and professional milieus that shape entrepreneurship (firms, policy makers) for guidance of scientific production.

The JT-60SA device has been designed as a highly shaped large superconducting tokamak with a variety of plasma actuators (heating, current drive, momentum input, stability control coils, resonant magnetic perturbation coils, W-shaped divertor, fuelling, pumping, etc) in order to satisfy the central research needs for ITER and DEMO. In the ITER- and DEMO-relevant plasma parameter regimes and with DEMO-equivalent plasma shapes, JT-60SA quantifies the operation limits, plasma responses and operational margins in terms of MHD stability, plasma transport and confinement, high-energy particle behaviour, pedestal structures, scrape-off layer and divertor characteristics. By integrating advanced studies in these research fields, the project proceeds 'simultaneous and steady-state sustainment of the key performances required for DEMO' with integrated control scenario development applicable to the highly self-regulating burning high-β high bootstrap current fraction plasmas.

The construct of food involvement in behavioral research: scale development and validation.

Science.gov (United States)

Bell, Rick; Marshall, David W

2003-06-01

The construct of involvement has been found to influence brand loyalty, product information search processing, responses to advertising communications, diffusion of innovations, and ultimately, product choice decisions. Traditionally, involvement has been defined as being a characteristic of either a product or of an individual. In the present research, we make an assumption that an individual's 'food involvement' is a somewhat stable characteristic and we hypothesized that involvement with foods would vary between individuals, that individuals who are more highly involved with food would be better able to discriminate between a set of food samples than would less food involved individuals, and that this discrimination would operate both in affective and perceptive relative judgments. Using standard scale construction techniques, we developed a measure of the characteristic of food involvement, based on activities relating to food acquisition, preparation, cooking, eating and disposal. After several iterations, a final 12-item measure was found to have good test-retest reliability and internal consistency within two subscales. A behavioral validation study demonstrated that measures of food involvement were associated with discrimination and hedonic ratings for a range of foods in a laboratory setting. These findings suggest that food involvement, as measured by the Food Involvement Scale, may be an important mediator to consider when undertaking research with food and food habits.
Food-pics: an image database for experimental research on eating and appetite.

Science.gov (United States)

Blechert, Jens; Meule, Adrian; Busch, Niko A; Ohla, Kathrin

2014-01-01

Our current environment is characterized by the omnipresence of food cues. The sight and smell of real foods, but also graphically depictions of appetizing foods, can guide our eating behavior, for example, by eliciting food craving and influencing food choice. The relevance of visual food cues on human information processing has been demonstrated by a growing body of studies employing food images across the disciplines of psychology, medicine, and neuroscience. However, currently used food image sets vary considerably across laboratories and image characteristics (contrast, brightness, etc.) and food composition (calories, macronutrients, etc.) are often unspecified. These factors might have contributed to some of the inconsistencies of this research. To remedy this, we developed food-pics, a picture database comprising 568 food images and 315 non-food images along with detailed meta-data. A total of N = 1988 individuals with large variance in age and weight from German speaking countries and North America provided normative ratings of valence, arousal, palatability, desire to eat, recognizability and visual complexity. Furthermore, data on macronutrients (g), energy density (kcal), and physical image characteristics (color composition, contrast, brightness, size, complexity) are provided. The food-pics image database is freely available under the creative commons license with the hope that the set will facilitate standardization and comparability across studies and advance experimental research on the determinants of eating behavior.

Cloud regimes as phase transitions

Science.gov (United States)

Stechmann, Samuel; Hottovy, Scott

2017-11-01

Clouds are repeatedly identified as a leading source of uncertainty in future climate predictions. Of particular importance are stratocumulus clouds, which can appear as either (i) closed cells that reflect solar radiation back to space or (ii) open cells that allow solar radiation to reach the Earth's surface. Here we show that these clouds regimes - open versus closed cells - fit the paradigm of a phase transition. In addition, this paradigm characterizes pockets of open cells (POCs) as the interface between the open- and closed-cell regimes, and it identifies shallow cumulus clouds as a regime of higher variability. This behavior can be understood using an idealized model for the dynamics of atmospheric water as a stochastic diffusion process. Similar viewpoints of deep convection and self-organized criticality will also be discussed. With these new conceptual viewpoints, ideas from statistical mechanics could potentially be used for understanding uncertainties related to clouds in the climate system and climate predictions.

Caloric restriction in the presence of attractive food cues: external cues, eating, and weight.

Science.gov (United States)

Polivy, Janet; Herman, C Peter; Coelho, Jennifer S

2008-08-06

A growing body of research on caloric restriction (CR) in many species of laboratory animals suggests that underfeeding leads to better health and longevity in the calorically-restricted animal (e.g., see [[34]. J.P. Pinel, S. Assanand and D.R. Lehman, (2000). Hunger, eating and ill health. Am Psychol, 55, 1105-1116.], for a review). Although some objections have been raised by scientists concerned about negative psychological and behavioral sequelae of such restriction, advocates of CR continue to urge people to adopt sharply reduced eating regimes in order to increase their longevity. Yet very few people are even attempting to reap the benefits of such restriction. The present paper explores one factor that may deter many humans from drastically reducing their food consumption--the presence of abundant, attractive food cues in the environment. Research on the influence of food cues on food-related behaviors is reviewed to demonstrate that the presence of food cues makes restriction of intake more difficult.
Identifying research advancements in supply chain risk management for Agri-food Industries: Literature review

Science.gov (United States)

Septiani, W.; Astuti, P.

2017-12-01

Agri-food supply chain has different characteristics related to the raw materials it uses. Food supply chain has a high risk of damage, thus drawing a lot of attention from researchers in supply chain management. This research aimed to investigate the development of supply chain risk management research on agri-food industries. These reviews were arranged in steps systematically, ranging from searching related to the review of SCRM paper, reviewing the general framework of SCRM and the framework of agri-food SCRM. Selection of literature review papers in the period 2005-2017, and obtained 45 papers. The results of the identification research were illustrated in a supply chain risk management framework model. This provided insight toward future research directions and needs.
Tracing Mississippi River influences in estuarine food webs of coastal Louisiana.

Science.gov (United States)

Wissel, Björn; Fry, Brian

2005-08-01

The Breton Sound estuary in southern Louisiana receives large amounts of Mississippi River water via a controlled diversion structure at the upstream end of the estuary. We used stable isotopes to trace spatial and seasonal responses of the downstream food web to winter and spring introductions of river water. Analysis of delta13C, delta15N, and delta34S in the common local consumers such as grass shrimp (Palaemonetes sp.), barnacles (Balanus sp.), and small plankton-feeding fish (bay anchovies, Anchoa mitchilli) showed that the diversion was associated with two of the five major source regimes that were supporting food webs: a river regime near the diversion and a river-influenced productive marsh regime farther away from the diversion. Mixing models identified a third river-influenced source regime at the marine end of the estuary where major natural discharge from the Bird's Foot Delta wraps around into estuarine waters. The remaining two source regimes represented typical estuarine conditions: local freshwater sources especially from precipitation and a brackish source regime representing higher salinity marine influences. Overall, the Mississippi River diversion accounted for 75% of food web support in the upper estuary and 25% in the middle estuary, with influence strongest along known flow pathways and closest to the diversion. Isotopes also traced seasonal changes in river contributions, and indicated increased plant community productivity along the major flow path of diversion water. In the Breton Sound estuary, bottom-up forcing of food webs is strongly linked to river introductions and discharge, occurring in spatial and temporal patterns predictable from known river input regimes and known hydrologic circulation patterns.
Research priorities for coordinating management of food safety and water quality.

Crohn, David M; Bianchi, Mary L

2008-01-01

Efforts to exclude disease organisms from farms growing irrigated lettuce and leafy vegetables on California's central coast are conflicting with traditionally accepted strategies to protect surface water quality. To begin resolving this dilemma, over 100 officials, researchers, and industry representatives gathered in April 2007 to set research priorities that could lead to effective co-management of both food safety and water quality. Following the meeting, research priorities were refined and ordered by way of a Delphi process completed by 35 meeting participants. Although water quality and food safety experts conceptualized the issues differently, there were no deep disagreements with respect to research needs. Top priority was given to investigating the fate of pathogens potentially present on farms. Intermediate priorities included characterizing the influence of specific farm management practices on food safety and improving our understanding of vector processes. A scientific subdiscipline focusing on competing risks is needed to characterize and resolve conflicts between human and environmental health.

Pietro Pulina

2012-07-01

Full Text Available This study analyzes the changes osberved in the agri-food system with the advent of logistical management of the flow of goods and information along the food supply chain. Agri-food functions and responsibilities towards society are also analyzed. This field of research has been widely explored in recent years following the development of the Corporate Social Responsibility (CSR certification in agri-business. The analysis starts by examining the coherence of the ethical basis of human choices in a homo oeconomicus framework in which social relationships are merely exploitable activities. CSR development is then studied in the light of the new stakeholder theory for firms. The main fields of economic research into sustainable development and the most important goals achieved are examined and the methodological perspectives of agricultural economics research will also be discussed.

Nano-food packaging: an overview of market, migration research, and safety regulations.

Science.gov (United States)

Bumbudsanpharoke, Nattinee; Ko, Seonghyuk

2015-05-01

Recently, food packages produced with nanoparticles, "nano-food packaging," have become more available in the current market. However, although the use of nanomaterials is increasing in food packaging applications, concern over toxicity affects consumer perceptions and acceptance. Quite a number of commercialized forms of nano-food packaging are coated or composited product with inorganic materials, for example, nanosilver and nanoclay as representative examples. Several studies have shown the possibility of nanomaterial migration from packaging or containers to foodstuff. The debate is still ongoing among researchers about the extent of migration and whether it is negligible and safe. Government agencies and stakeholders must hurry to determine use limitations and release conclusive legislation and regulations as soon as possible since nano-food packaging may have great impacts on human health. This paper aims to review the availability of nano-food packaging in the current market, report case studies on nanomaterial migration, and present the current status of safety regulations and management of nano-food packaging in leading countries across regions. This review should enable governments and researchers to develop further nanomaterial risk assessment studies. © 2015 Institute of Food Technologists®
Future development, innovation and promotion of European unique food: an interdisciplinary research framework perspective.

Science.gov (United States)

Byrne, Derek V; Waehrens, Sandra S; O'Sullivan, Maurice G

2013-11-01

Unique food products constitute a very important element of European food business, culture, identity and heritage. Understanding the uniqueness of food in Europe from a research-based interdisciplinary perspective will be a critical factor in promoting the competitiveness of artisanal food industries going forward both locally and internationally. Success will support the competitiveness of the European food industry, in particular, small and medium enterprises, by enabling substantial product differentiation potential for producers and providing ample variety in food choice for the consumer. In addition, it will contribute to promotion of sustainable agriculture and development of rural areas, protecting them from depopulation. In order to meet the demands of a developing fundamental shift in European Union agricultural focus to greener, sustainable farming practices and wider rural development and to ensure success for local small-scale producers, this paper discusses the future direction of research in the field of unique European foods. The paper presents a perspective which promotes optimisation and innovation in unique food products in Europe through the integration of advanced knowledge and technologies. A framework is presented covering location, identity, perception and well-being as research areas needing synergy to bridge the research knowledge deficit in determination and specification of food identity in the European Union. The ultimate aim being promotion of sustainable agriculture and rural development, particularly in territories across the European Union where unique food is strategically and scientifically under-defined. © 2013 Society of Chemical Industry.

Prima facie reasons to question enclosed intellectual property regimes and favor open-source regimes for germplasm.

Science.gov (United States)

Halpert, Madeleine-Thérèse; Chappell, M Jahi

2017-01-01

In principle, intellectual property protections (IPPs) promote and protect important but costly investment in research and development. However, the empirical reality of IPPs has often gone without critical evaluation, and the potential of alternative approaches to lend equal or greater support for useful innovation is rarely considered. In this paper, we review the mounting evidence that the global intellectual property regime (IPR) for germplasm has been neither necessary nor sufficient to generate socially beneficial improvements in crop plants and maintain agrobiodiversity. Instead, based on our analysis, the dominant global IPR appears to have contributed to consolidation in the seed industry while failing to genuinely engage with the potential of alternatives to support social goods such as food security, adaptability, and resilience. The dominant IPR also constrains collaborative and cumulative plant breeding processes that are built upon the work of countless farmers past and present. Given the likely limits of current IPR, we propose that social goods in agriculture may be better supported by alternative approaches, warranting a rapid move away from the dominant single-dimensional focus on encouraging innovation through ensuring monopoly profits to IPP holders.

Effect of a Publicly Accessible Disclosure System on Food Safety Inspection Scores in Retail and Food Service Establishments.

Science.gov (United States)

Choi, Jihee; Scharff, Robert L

2017-07-01

The increased frequency with which people are dining out coupled with an increase in the publicity of foodborne disease outbreaks has led the public to an increased awareness of food safety issues associated with food service establishments. To accommodate consumer needs, local health departments have increasingly publicized food establishments' health inspection scores. The objective of this study was to estimate the effect of the color-coded inspection score disclosure system in place since 2006 in Columbus, OH, by controlling for several confounding factors. This study incorporated cross-sectional time series data from food safety inspections performed from the Columbus Public Health Department. An ordinary least squares regression was used to assess the effect of the new inspection regime. The introduction of the new color-coded food safety inspection disclosure system increased inspection scores for all types of establishments and for most types of inspections, although significant differences were found in the degree of improvement. Overall, scores increased significantly by 1.14 points (of 100 possible). An exception to the positive results was found for inspections in response to foodborne disease complaints. Scores for these inspections declined significantly by 10.2 points. These results should be useful for both food safety researchers and public health decision makers.

Engster, Daniel; Stensöta, Helena Olofsdotter

2011-01-01

Researchers have studied the impact of different welfare state regimes, and particularly family policy regimes, on gender equality. Very little research has been conducted, however, on the association between different family policy regimes and children's well-being. This article explores how the different family policy regimes of twenty OECD countries relate to children's well-being in the areas of child poverty, child mortality, and educational attainment and achievement. We focus specifically on three family policies: family cash and tax benefits, paid parenting leaves, and public child care support. Using panel data for the years 1995, 2000, and 2005, we test the association between these policies and child well-being while holding constant for a number of structural and policy variables. Our analysis shows that the dual-earner regimes, combining high levels of support for paid parenting leaves and public child care, are strongly associated with low levels of child poverty and child mortality. We find little long-term effect of family policies on educational achievement, but a significant positive correlation between high family policy support and higher educational attainment. We conclude that family policies have a significant impact on improving children's well-being, and that dual-earner regimes represent the best practice for promoting children's health and development.
Retail food environments in Canada: Maximizing the impact of research, policy and practice.

Science.gov (United States)

Minaker, Leia M

2016-06-09

Retail food environments are gaining national and international attention as important determinants of population dietary intake. Communities across Canada are beginning to discuss and implement programs and policies to create supportive retail food environments. Three considerations should drive the selection of food environment assessment methods: relevance (What is the problem, and how is it related to dietary outcomes?); resources (What human, time and financial resources are required to undertake an assessment?); and response (How will policy-makers find meaning out of and act on the information gained through the food environment assessment?). Ultimately, food environment assessments should be conducted in the context of stakeholder buy-in and multi-sectoral partnerships, since food environment solutions require multi-sectoral action. Partnerships between public health actors and the food and beverage industry can be challenging, especially when mandates are not aligned. Clarifying the motivations, expectations and roles of all stakeholders takes time but is important if the impact of food environment research, policy and practice is to be maximized. The articles contained in this special supplementary issue describe ongoing food environments research across Canada and fill some of the important gaps in the current body of Canadian food environments literature.
Policy Ideas, Knowledge Regimes and Comparative Political Economy

Despite much attention to how ideas affect policy making, where these ideas come from is a blind spot in comparative political economy. We show that an important source of policy ideas are knowledge regimes—fields of policy research organizations. We show as well that the organization of knowledge...... to restore it by transforming their knowledge regimes, albeit in ways that are still shaped by the surrounding political and economic institutions.

Nanomaterials have gained importance in various fields of science, technology, medicine, colloid technologies, diagnostics, drug delivery, personal care applications and others due to their small size and unique physico-chemical characteristic. Apart from above mentioned area, it is also extensively being used in food sector specifically in preservation and packaging. The future applications in food can also be extended to improve the shelf life, food quality, safety, fortification and biosensors for contaminated or spoiled food or food packaging. Different types and shapes of nanomaterials are being employed depending upon the need and nature of the food. Characterisation of these nanomaterials is essential to understand the interaction with the food matrix and also with biological compartment. This review is focused on application of nanotechnology in food industries. It also gives insight on commercial products in market with usage of nanomaterials, current research and future aspects in these areas. Currently, they are being incorporated into commercial products at a faster rate than the development of knowledge and regulations to mitigate potential health and environmental impacts associated with their manufacturing, application and disposal. As nanomaterials are finding new application every day, care should be taken about their potential toxic effects.
What Do We Know about Hybrid Regimes after Two Decades of Scholarship?

Directory of Open Access Journals (Sweden)

Mariam Mufti

2018-06-01

Full Text Available In two decades of scholarship on hybrid regimes two significant advancements have been made. First, scholars have emphasized that the hybrid regimes that emerged in the post-Cold War era should not be treated as diminished sub-types of democracy, and second, regime type is a multi-dimensional concept. This review essay further contends that losing the lexicon of hybridity and focusing on a single dimension of regime type—flawed electoral competition—has prevented an examination of extra-electoral factors that are necessary for understanding how regimes are differently hybrid, why there is such immense variation in the outcome of elections and why these regimes are constantly in flux. Therefore, a key recommendation emerging from this review of the scholarship is that to achieve a more thorough, multi-dimensional assessment of hybrid regimes, further research ought to be driven by nested research designs in which qualitative and quantitative approaches can be used to advance mid-range theory building.
Conceptual proposals for measuring the impact of international regimes on energy security

International Nuclear Information System (INIS)

Sander, Michael

2013-01-01

The paper proposes two concepts to assess the effect of international regimes on energy security. Existing indicators focus mainly on state-level factors, excluding international influences. International relation scholars on the other hand see a clear connection between international regimes and stable energy relations. International regimes stabilise energy relations by providing frameworks for negotiations, defining, controlling and sanctioning compliance and allowing the actors to engage in package deals. The researcher needs to include these factors in a complete assessment of political energy security risks. As first step, the paper uses the effectiveness of control mechanisms as basis for such consideration. It refers specifically to international arbitration as the most important control mechanism in international energy relations. The simplest measurement option is the share of a county's energy imports covered by a certain regime. The paper applies the Oslo-Potsdam-Solution to account for outcome effectiveness. It applies a variant of the International Regimes Data Base protocol to account for effective regime structures. In a last section, the paper proposes some possible paths for future research. - Highlights: • International regimes mitigate political risks for energy supply and must be considered. • The paper proposes two concepts to measure energy regime effectiveness. • The OPS-variant measures output, the IRDB-variant measures structure effectiveness. • The paper offers a preliminary feasibility test for the concepts. • Finally, it suggests further roads for research
Back by Popular Demand: A Narrative Review on the History of Food Addiction Research

Meule, Adrian

2015-01-01

In recent years, the concept of food addiction has gained more and more popularity. This approach acknowledges the apparent parallels between substance use disorders and overeating of highly palatable, high-caloric foods. Part of this discussion includes that “hyperpalatable” foods may have an addictive potential because of increased potency due to certain nutrients or additives. Although this idea seems to be relatively new, research on food addiction actually encompasses several decades, a fact that often remains unrecognized. Scientific use of the term addiction in reference to chocolate even dates back to the 19th century. In the 20th century, food addiction research underwent several paradigm shifts, which include changing foci on anorexia nervosa, bulimia nervosa, obesity, or binge eating disorder. Thus, the purpose of this review is to describe the history and state of the art of food addiction research and to demonstrate its development and refinement of definitions and methodologies.

Impression management and food intake. Current directions in research.

Vartanian, Lenny R

2015-03-01

This paper reviews recent research on consumption stereotypes (judgments of others based on what they eat) and impression management (modifying one's eating behavior in order to create a particular impression). A major recent focus in the literature has been on masculinity and meat eating, with research showing that meat is strongly associated with masculinity, and that individuals who follow a meat-based diet are perceived as more masculine than are individuals who follow a vegetarian diet. Although direct evidence for impression management through food intake remains sparse, a number of methodological approaches (including priming techniques and ecological valid assessments) are described that could be used in future research to identify the motives underlying people's eating behavior. Consumption stereotypes and impression management may be important influences on people's eating behavior, but the complexities of how, when, and for whom these factors influence food intake are still not well understood.

Thorsøe, Martin Hermansen; Alrøe, Hugo Fjelsted; Noe, Egon

2014-01-01

Assessing the overall effects of organic food systems is important, but also a challenge because organic food systems cannot be fully assessed from one single research perspective. The aim of our research was to determine the role of values in assessments of organic food systems as a basis...... for discussing the implications of combining multiple perspectives in overall sustainability assessments of the food system. We explored how values were embedded in five research perspectives: (1) food science, (2) discourse analysis, (3) phenomenology, (4) neoclassical welfare economics, and (5) actor......-network theory. Value has various meanings according to different scientific perspectives. A strategy for including and balancing different forms of knowledge in overall assessments of the effects of food systems is needed. Based on the analysis, we recommend four courses of action: (1) elucidate values...
The influence of organic production on food quality - research findings, gaps and future challenges.

Although several meta-analysis studies have been published comparing the quality of food derived from organic and non-organic origin, it is still not clear if food from organic production per se can guarantee product-related added value to consumers. This paper aims to summarize the status quo in order to identify research gaps and suggest future research challenges. Organic food is described according to a quality model already published. The influence of organic production on food quality is structured in primary production and processing. Furthermore, organic food authentication is discussed. Organic food seems to contain fewer pesticide residues and statistically more selected health-related compounds such as polyphenols in plant products and polyunsaturated fatty acids in milk and meat products, but the health relevance for consumers is not clear yet. Comparing food from organic origin with so called 'conventional' food seems not to be appropriate, because 'conventional' is not defined. In organic food quality research a system approach is needed from which systemic markers can be selected. Research on the impact of processing technologies on the quality according to organic principles seems of high relevance, since most of the food is processed. © 2014 Society of Chemical Industry.

Full Text Available Since the post-war period, Colombian agriculture has been reshaped mainly by international measures. The post-war international food order (called food regime over time has exacerbated Colombian rural problems linked to land issues. Emphasizing in five groups of crops (Cereals, Fruits, Pulses, Roots and Tubers, and Vegetables this article found how Colombia has turned from being a self-sufficient producer into a net importer. Consequently, the food regime has reshaped agricultural structures where policies have favored certain groups rather than solving land issues. Bio-fuel crop policies are following the same direction, jeopardizing food sovereignty and deepening rural Colombian problems.

To describe the influence of the food industry in health research, observing how funding influences health outcomes and the quality of the studies. We performed a systematic review in MEDLINE, Cochrane Library Plus and Scopus using the MESH "Food Industry", "Food-Processing Industry", "Biomedical Research", "Research Support as Topic", and the keywords "Industry Sponsorship" and "Funding Source". The quality was assessed using the PRISMA guidelines. We revised 1,506 articles and 10 were included; two reviewed the relationship between funding-outcomes and quality-outcomes; six focused on the funding-outcomes relationship; and the other two focused on methodological quality. Six showed that funding from the food industry resulted in more favourable outcomes for their products. No differences in quality were found in relation to the funding source, but those which did not declare their funding had a worse quality. Studies funded by the food industry showed favourable results for their products. However, this fact did not affect the quality of the studies. Copyright © 2017 SESPAS.

Full Text Available Public-Private Partnerships (PPPs have emerged along with the growing role of corporations in global development. One of the largest forms of PPP today is the UN Global Compact. The UN Global Compact involves of companies, NGOs, IGOs and state governments. All of them are trying to realize globalization with a more humanist face with attention to the protection of human rights, environment, labor standards and anti-corruption. Engaging private actors in global governance, The UN Global Compact raises many issues such as power, authority, and legitimacy. The effort to tackle it all is to increase PPP accountability. This research seeks to describe what efforts can be made to enhance private accountability within the international regime. The research undertaken is a descriptive study, focuses on public-private partnerships in the UN Global Compact regime. The study found that there were two attempts that could be done. First, by involving the stakeholders in the development of procedures, mechanisms, reporting and monitoring associated with trying to improve the company’s reputation. Second, by looking at corporate relations as agent and UN Global Compact as principal in principal-agent relation in the international regime.

Although research shows that "food parenting practices" can impact children's diet and eating habits, current understanding of the impact of specific practices has been limited by inconsistencies in terminology and definitions. This article represents a critical appraisal of food parenting practices, including clear terminology and definitions, by a working group of content experts. The result of this effort was the development of a content map for future research that presents 3 overarching, higher-order food parenting constructs--coercive control, structure, and autonomy support--as well as specific practice subconstructs. Coercive control includes restriction, pressure to eat, threats and bribes, and using food to control negative emotions. Structure includes rules and limits, limited/guided choices, monitoring, meal- and snacktime routines, modeling, food availability and accessibility, food preparation, and unstructured practices. Autonomy support includes nutrition education, child involvement, encouragement, praise, reasoning, and negotiation. Literature on each construct is reviewed, and directions for future research are offered. Clear terminology and definitions should facilitate cross-study comparisons and minimize conflicting findings resulting from previous discrepancies in construct operationalization. © The Author(s) 2016.

This paper provides guidance on how to assess the safety of foods derived from genetically modified crops (GM crops); it summarises conclusions and recommendations of Working Group 1 of the ENTRANSFOOD project. The paper provides an approach for adapting the test strategy to the characteristics of the modified crop and the introduced trait, and assessing potential unintended effects from the genetic modification. The proposed approach to safety assessment starts with the comparison of the new GM crop with a traditional counterpart that is generally accepted as safe based on a history of human food use (the concept of substantial equivalence). This case-focused approach ensures that foods derived from GM crops that have passed this extensive test-regime are as safe and nutritious as currently consumed plant-derived foods. The approach is suitable for current and future GM crops with more complex modifications. First, the paper reviews test methods developed for the risk assessment of chemicals, including food additives and pesticides, discussing which of these methods are suitable for the assessment of recombinant proteins and whole foods. Second, the paper presents a systematic approach to combine test methods for the safety assessment of foods derived from a specific GM crop. Third, the paper provides an overview on developments in this area that may prove of use in the safety assessment of GM crops, and recommendations for research priorities. It is concluded that the combination of existing test methods provides a sound test-regime to assess the safety of GM crops. Advances in our understanding of molecular biology, biochemistry, and nutrition may in future allow further improvement of test methods that will over time render the safety assessment of foods even more effective and informative.

Public-private interactions in global food safety governance.

Science.gov (United States)

Lin, Ching-Fu

2014-01-01

In response to an apparent decline in global food safety, numerous public and private regulatory initiatives have emerged to restore public confidence. This trend has been particularly marked by the growing influence of private regulators such as multinational food companies, supermarket chains and non-governmental organizations (NGOs), who employ private standards, certification protocols, third-party auditing, and transnational contracting practices. This paper explores how the structure and processes of private food safety governance interact with traditional public governance regimes, focusing on Global Good Agricultural Practices (GlobalGAP) as a primary example of the former. Due to the inefficiency and ineffectiveness of public regulation in the face of global problems, private governance in food safety has gradually replaced states' command-and-control regulation with more flexible, market-oriented mechanisms. The paper concludes by emphasizing the importance of constructive regime interaction instead of institutional boundary building to global food safety governance. Public and private ordering must each play a role as integral parts of a larger, dynamic and evolving governance complex.
Shared voices, different worlds: Process and product in the Food Dignity action research project

Full Text Available Diversity of perspective makes for greater depth when painting a portrait of community life. But embracing the idea of representing true diversity in a formal research project is a whole lot easier than putting it into practice. The three dozen members of the Food Dignity action research team, now entering the fourth year of a five-year project, are intimately familiar with this challenge. In this article, four of the collaborators explore the intricacies of navigating what it means to bring together a genuine cross-section of community-based activists and academics in an effort to draw on one another’s professional and personal strengths to collect and disseminate research findings that represent the truth of a community’s experiences, and are ultimately disseminated in a way that brings tangible benefit to the heart and soul of that community. The authors include Food Dignity’s principal investigator (Porter and three community organisers (Marshall, Herrera and Woodsum in organisations that have partnered with Food Dignity. Two of the organisers (Herrera and Woodsum also serve project-wide roles. These collaborators share their personal and professional hopes, struggles, concerns, successes and failures as participants in this cutting-edge effort to equalise community and university partnerships in research.

Effect of dietary regime on metabolic control in phenylketonuria: Is exact calculation of phenylalanine intake really necessary?

Directory of Open Access Journals (Sweden)

Carmen Rohde

2015-12-01

Conclusion: Exact calculation of Phe content of all food is not necessary to achieve good metabolic control in children and adolescents with PKU. Excluding special low protein food, as well as fruit and vegetables from calculation of Phe-intake has no impact on metabolic control. However including protein rich food into the diet and simply estimating all Phe-intake appears insufficient. The simplification of dietary regime may be helpful in enhancing acceptability and feasibility.

The aim of this paper was to give an overview of relevant streams of research that can form a basis for research on user-oriented innovation in the food sector. We define user-oriented innovation as a process towards the development of a new product or service in which an integrated analysis...... and understanding of the users' wants, needs and preference formation play a key role. We distinguish three relevant streams of research that may provide a basis for research on user-oriented innovation in the food sector: research on the formation of user preferences, research on innovation management......, and research on interactive innovation. We show that the relevance of these three streams of research for the food sector depends on which type of innovation we are dealing with, and we propose a distinction of three types of food innovations depending on which actors in the food chain are involved...
The legacy of large regime shifts in shallow lakes.

Ecological shifts in shallow lakes from clear-water macrophyte-dominated to turbid-water phytoplankton-dominated are generally thought of as rapid short-term transitions. Diatom remains in sediment records from shallow lakes in the Prairie Pothole Region of North America provide new evidence that the long-term ecological stability of these lakes is defined by the legacy of large regime shifts. We examine the modern and historical stability of 11 shallow lakes. Currently, four of the lakes are in a clear-water state, three are consistently turbid-water, and four have been observed to change state from year to year (transitional). Lake sediment records spanning the past 150-200 yr suggest that (1) the diatom assemblage is characteristic of either clear or turbid lakes, (2) prior to significant landscape alteration, all of the lakes existed in a regime of a stable clear-water state, (3) lakes that are currently classified as turbid or transitional have experienced one strong regime shift over the past 150-200 yr and have since remained in a regime where turbid-water predominates, and (4) top-down impacts to the lake food-web from fish introductions appear to be the dominant driver of strong regime shifts and not increased nutrient availability. Based on our findings we demonstrate a method that could be used by lake managers to identify lakes that have an ecological history close to the clear-turbid regime threshold; such lakes might more easily be returned to a clear-water state through biomanipulation. The unfortunate reality is that many of these lakes are now part of a managed landscape and will likely require continued intervention. © 2016 by the Ecological Society of America.
Guide for dosimetry in radiation research on food and agricultural products

International Nuclear Information System (INIS)

2002-01-01

This guide covers the minimum requirements for dosimetry and absorbed-dose validation needed to conduct research on the irradiation of food and agricultural products. Such research includes establishment of the quantitative relationship between the absorbed dose and the relevant effects in these products. This guide also describes the overall need for dosimetry in such research, and in reporting of the results. This guide is intended for use by research scientists in the food and agricultural communities, and not just scientists conducting irradiation research. It, therefore, includes more tutorial information than most other ASTM and ISO/ASTM dosimetry standards for radiation processing. This guide is in no way intended to limit the flexibility of the experimenter in the experimental design. However, the radiation source and experimental set up should be chosen such that the results of the experiment will be beneficial and understandable to other scientists, regulatory agencies, and the food and agricultural communities. The effects produced by ionizing radiation in biological systems depend on a large number of factors which may be physical, physiological, or chemical. Although not treated in detail in this guide, quantitative data of environmental factors that may affect the absorbed-dose response of dosimeters, such as temperature and moisture content in the food or agricultural products should be reported. The overall uncertainty in the absorbed-dose measurement and the inherent absorbed-dose range within the specimen should be taken into account in the design of an experiment. The guide covers research conducted using the following types of ionizing radiation: gamma rays, bremsstrahlung X-rays, and electron beams. This guide does not include other aspects of radiation processing research, such as planning of the experimental design. Dosimetry must be considered as an integral part of the experimental design. The guide does not include dosimetry for irradiator

Full Text Available In present paper there is the consideration of mathematical model of food plant (resource - consumer (insect population - pathogen system dynamics which is constructed as a system of ordinary differential equations. The dynamic regimes of model are analyzed and, in particular, with the help of numerical methods it is shown that trigger regimes (regimes with two stable attractors can be realized in model under very simple assumptions about ecological and intra-population processes functioning. Within the framework of model it was assumed that the rate of food flow into the system is constant and functioning of intra-population selfregulative mechanisms can be described by Verhulst model. As it was found, trigger regimes are different with respect to their properties: in particular, in model the trigger regimes with one of stable stationary points on the coordinate plane can be realized (it corresponds to the situation when sick individuals in population are absent and their appearance in small volume leads to their asymptotic elimination; also the regimes with several nonzero stationary states and stable periodic fluctuations were found.

Combination processes for food irradiation. Proceedings of the final research co-ordination meeting

International Nuclear Information System (INIS)

1998-01-01

There is an increasing consumer demand for food that is safe, minimally processed, visually attractive, full flavoured, nutritious, and convenient to prepare and serve, that has fewer preservatives, and that is available throughout the year at an affordable cost. Consumer concern and regulatory restrictions on the use of preservatives and pesticides in food are adversely affecting international trade in many food products. As a result, minimally processed, chilled foods and ready to eat foods are increasingly being marketed to satisfy consumer demand in both developed and developing countries. However, such foods could introduce new microbiological risks to the population, especially to those who are immunocompromised or generally at risk (children, pregnant women, the elderly, etc.). In view of these factors, a 5 year Co-ordinated Research Programme (CRP) on Irradiation in Combination with Other Processes for Improving Food Quality was initiated in 1991 by the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency through their Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. The objectives of this CRP were to evaluate: 1) Combination treatment involving irradiation in order to extend the self-life of meat, seafood, fruits and vegetables at refrigeration temperatures and under ambient conditions; 2) Combination treatment involving irradiation in order to ensure the microbiological safety of foods, both individual and composite, including prepared meals; 3) Shelf-life extension of chilled, prepared meals and the development of shelf stable food and food components through combination treatment involving irradiation; 4) Energy requirements of combination processes involving irradiation in comparison to other food processes. Scientists from 14 countries participated in the CRP by carrying out the work under Research Contracts and Agreements with the Joint FAO/IAEA Division. The first Research Co

Internal boundaries in multiphase flow greatly complicate fluid-dynamic and heat-transfer descriptions. Different flow regimes or topological configurations can have radically dissimilar interfacial and wall mass, momentum, and energy exchanges. To model the flow dynamics properly requires estimates of these rates. In this paper the common flow regimes for gas-liquid systems are defined and the techniques used to estimate the extent of a particular regime are described. Also, the current computer-code procedures are delineated and introduce a potentially better method is introduced
Understanding infants' and children's social learning about foods: previous research and new prospects.

Shutts, Kristin; Kinzler, Katherine D; DeJesus, Jasmine M

2013-03-01

Developmental psychologists have devoted significant attention to investigating how children learn from others' actions, emotions, and testimony. Yet most of this research has examined children's socially guided learning about artifacts. The present article focuses on a domain that has received limited attention from those interested in the development of social cognition: food. We begin by reviewing the available literature on infants' and children's development in the food domain and identify situations in which children evidence both successes and failures in their interactions with foods. We focus specifically on the role that other people play in guiding what children eat and argue that understanding patterns of successes and failures in the food domain requires an appreciation of eating as a social phenomenon. We next propose a series of questions for future research and suggest that examining food selection as a social phenomenon can shed light on mechanisms underlying children's learning from others and provide ideas for promoting healthy social relationships and eating behaviors early in development.

Furuya, Tsuyoshi

1989-01-01

Twenty years have elapsed since the general research on food irradiation was begun in Japan as the new technology for food preservation, and the research on the wholesomeness of irradiated foods has been carried out in wide range together with the research on irradiation effect, irradiation techniques and economical efficiency. The wholesomeness of irradiated foods includes chronic toxicity including carcinogenic property in the continuous intake for long period, the effect to reproduction function over many generations and the possibility of giving hereditary injury to cells, the nutritional adequacy required for the sustenance of life and the increase of health, and microbiological safety. In Japan, the research on food irradiation was designated as an atomic energy specific general research, and as the objects of research, potato and onion for the prevention of germination, rice and wheat for the protection from noxious insects, fish paste products, wienerwurst and mandarin orange for sterilization were selected. For the irradiation, Co-60 gamma ray was used except the case of mandarin orange using electron beam. The research on all 7 items was finished, and the irradiation of potato was permitted. (K.I.)

Cai, Ximing; Wallington, Kevin; Shafiee-Jood, Majid; Marston, Landon

2018-01-01

Studies on the food, energy, and water (FEW) nexus lay a shared foundation for researchers, policy makers, practitioners, and stakeholders to understand and manage linked production, utilization, and security of FEW systems. The FEW nexus paradigm provides the water community specific channels to move forward in interdisciplinary research where integrated water resources management (IWRM) has fallen short. Here, we help water researchers identify, articulate, utilize, and extend our disciplinary strengths within the broader FEW communities, while informing scientists in the food and energy domains about our unique skillset. This paper explores the relevance of existing and ongoing scholarship within the water community, as well as current research needs, for understanding FEW processes and systems and implementing FEW solutions through innovations in technologies, infrastructures, and policies. Following the historical efforts in IWRM, hydrologists, water resources engineers, economists, and policy analysts are provided opportunities for interdisciplinary studies among themselves and in collaboration with energy and food communities, united by a common path to achieve sustainability development goals.

In recent years, a research area has emerged within social determinants of health that examines the role of politics, expressed as political traditions/parties and welfare state characteristics, on population health. To better understand and synthesise this growing body of evidence, the present literature review, informed by a political economy of health and welfare regimes framework, located 73 empirical and comparative studies on politics and health, meeting our inclusion criteria in three databases: PubMed (1948-), Sociological Abstracts (1953-), and ISI Web of Science (1900-). We identified two major research programmes, welfare regimes and democracy, and two emerging programmes, political tradition and globalisation. Primary findings include: (1) left and egalitarian political traditions on population health are the most salutary, consistent, and substantial; (2) the health impacts of advanced and liberal democracies are also positive and large; (3) welfare regime studies, primarily conducted among wealthy countries, find that social democratic regimes tend to fare best with absolute health outcomes yet consistently in terms of relative health inequalities; and (4) globalisation defined as dependency indicators such as trade, foreign investment, and national debt is negatively associated with population health. We end by discussing epistemological, theoretical, and methodological issues for consideration for future research. © 2011 The Authors.

Over the past few decades, the field of food security has witnessed numerous problems and incidents that have garnered public attention. Given this serious situation, the food traceability system (FTS) has become part of the expanding food safety continuum to reduce the risk of food safety problems. This article reviews a great deal of the related literature and results from previous studies of FTS to corroborate this contention. This article describes the development and benefits of FTS in developed countries like the United States of America (USA), Japan, and some European countries. Problems with existing FTS in China are noted, including a lack of a complete database, inadequate laws and regulations, and lagging technological research into FTS. This article puts forward several suggestions for the future, including improvement of information websites, clarification of regulatory responsibilities, and promotion of technological research.

VanHeel, Nancy; Pettit, Janet; Rice, Barbara; Smith, Scott M.

2003-01-01

Food and nutrient databases are populated with data obtained from a variety of sources including USDA Reference Tables, scientific journals, food manufacturers and foreign food tables. The food and nutrient database maintained by the Nutrition Coordinating Center (NCC) at the University of Minnesota is continually updated with current nutrient data and continues to be expanded with additional nutrient fields to meet diverse research endeavors. Data are strictly evaluated for reliability and relevance before incorporation into the database; however, the values are obtained from various sources and food samples rather than from direct chemical analysis of specific foods. Precise nutrient values for specific foods are essential to the nutrition program at the National Aeronautics and Space Administration (NASA). Specific foods to be included in the menus of astronauts are chemically analyzed at the Johnson Space Center for selected nutrients. A request from NASA for a method to enter the chemically analyzed nutrient values for these space flight food items into the Nutrition Data System for Research (NDS-R) software resulted in modification of the database and interview system for use by NASA, with further modification to extend the method for related uses by more typical research studies.

DiRienzo, Douglas

2016-03-01

Nutritional interventions to help prevent stunting, particularly in the first 1000 days from conception to 2 years of a child's life, are a major focus of numerous food aid organizations worldwide. Dairy ingredients can play an important role in enhancing the nutritional value and effectiveness of food products used in food aid. This article addresses gaps in research on malnutrition from both a broad perspective and specific to dairy ingredients. Narrative review. From a broad perspective, there is a need for gaining a consensus by the research community and funders of research on best practices for protocol development, outcomes measured, and reporting of study outcomes. Identification of biomarkers and rapid screening methods and consistent application of their use would expedite future research. A better understanding of nutritional requirements for malnourished populations, including the effects of energy deficits and disease on those requirements, is needed. More specific to dairy ingredients, a key research question is: Does dairy protein or the package of nutrients provided by dairy ingredients have a unique impact on growth, and if so, how? Also, data on the optimal levels of dairy ingredients based on the effective cost of treatment are needed, particularly in the treatment and prevention of moderate acute malnutrition and during pregnancy. © The Author(s) 2016.

Young, Ian; Thaivalappil, Abhinand; Reimer, Danielle; Greig, Judy

2017-12-01

Farmers' markets are increasingly popular venues in North America for the sale of fresh produce and other foods. However, the nature of their operation can present possible food safety issues, challenges, and risks to consumers. A knowledge synthesis was conducted to identify, characterize, and summarize published research on the microbial food safety issues and implications associated with farmers' markets. A scoping review was conducted using the following steps: comprehensive search strategy, relevance screening of abstracts, and characterization of relevant articles. Two subsets of data were prioritized for more detailed systematic review (data extraction and risk-of-bias assessment) and meta-analysis: (i) studies comparing the microbial safety of foods from farmers' markets versus other sources and (ii) studies evaluating the use of food safety practices at farmers' markets. Overall, 83 relevant studies were identified. The majority of studies were published as journal articles (64%), used a cross-sectional design (81%), and were conducted in the United States (78%). Most studies (39%; n = 32) investigated stakeholder, mostly consumer (n = 22), attitudes toward food safety at farmers' markets. Limited but heterogeneous evidence indicated a higher prevalence of Campylobacter and Salmonella in chicken meat from farmers' markets versus other retail sources, but there was no difference in the microbial contamination of fresh produce. Studies evaluating the use of food safety practices at farmers' markets identified some gaps; for example, the average prevalence of vendor hand washing was 4% (95% confidence interval: 0 to 11%; I 2 = 27%; n = 5 studies). Twelve foodborne outbreaks and case reports were identified, resulting in a total of 411 illnesses, 38 hospitalizations, and two deaths from 1994 to 2016. Only five intervention studies were identified. Key knowledge gaps and areas warranting future research, training, and education are highlighted and discussed.

Jensen, Chad D; Duraccio, Kara M; Barnett, Kimberly A; Stevens, Kimberly S

2016-12-01

Research examining effects of visual food cues on appetite-related brain processes and eating behavior has proliferated. Recently investigators have developed food image databases for use across experimental studies examining appetite and eating behavior. The food-pics image database represents a standardized, freely available image library originally validated in a large sample primarily comprised of adults. The suitability of the images for use with adolescents has not been investigated. The aim of the present study was to evaluate the appropriateness of the food-pics image library for appetite and eating research with adolescents. Three hundred and seven adolescents (ages 12-17) provided ratings of recognizability, palatability, and desire to eat, for images from the food-pics database. Moreover, participants rated the caloric content (high vs. low) and healthiness (healthy vs. unhealthy) of each image. Adolescents rated approximately 75% of the food images as recognizable. Approximately 65% of recognizable images were correctly categorized as high vs. low calorie and 63% were correctly classified as healthy vs. unhealthy in 80% or more of image ratings. These results suggest that a smaller subset of the food-pics image database is appropriate for use with adolescents. With some modifications to included images, the food-pics image database appears to be appropriate for use in experimental appetite and eating-related research conducted with adolescents.

Full Text Available This study aims to highlight the status of agricultural R&D in South Asia and contends that creating an effective agricultural research and innovation systems is a vital element to ensure food security in this region. South Asia is home to around one-fourth of mankind and houses the largest proportion of undernourished people in the world. Despite a period of marked economic growth averaging 6% a year over the past two decades, it remains the world's second poorest region contributing a mere 2.2% in global annual GDP. Agriculture is the mainstay of South Asian economy employing around 60% of the total workforce and generating around 20% of total GDP. South Asia has the recognition of being the second most food-insecure region next only to sub-Saharan Africa. Though there is growing evidence that technological innovation has a key role to play in increasing agricultural production and strengthening food security, agricultural research and development (R&D sector has failed to garner sufficient attention till now. This study also depicts the current situation of food security in South Asia and illustrates how agricultural education and innovation hold the master key to solve the food security issues for the world's most densely populated region.

Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological potential (i.e. potential vegetation), and often fail to account for ongoing changes due to stressors such as land use change and climate change and their effects on plant and animal communities. We use Fisher information, an information theory-based method, on both terrestrial and aquatic animal data (U.S. Breeding Bird Survey and marine zooplankton) to identify ecological boundaries, and compare our results to traditional early warning indicators, conventional ecoregion maps and multivariate analyses such as nMDS and cluster analysis. We successfully detected spatial regimes and transitions in both terrestrial and aquatic systems using Fisher information. Furthermore, Fisher information provided explicit spatial information about community change that is absent from other multivariate approaches. Our results suggest that defining spatial regimes based on animal communities may better reflect ecological reality than do traditional ecoregion maps, especially in our current era of rapid and unpredictable ecological change.

The quality concern of food and agricultural products has become more and more significant. The related technologies for nondestructive measurement or quality control of food products have been the focus of many researches. Terahertz (THz) radiation, or THz wave, the least explored region of the spectrum, is the electromagnetic wave that lies between mid-infrared and microwave radiation, which has very important research and application values. THz spectroscopy and THz imaging technique are the two main applications of THz wave. During the past decade, THz waves have been used to characterize the electronic, vibrational and compositional properties of solid, liquid and gas phase materials. Recently, THz technology has gained a lot of attention of researchers in various fields from biological spectral analysis to bio-medical imaging due to its unique features compared with microwave and optical waves. In the present paper, the properties of THz wave and its uniqueness in sensing and imaging applications were discussed. The most recent researches on THz technology used in food quality control and agricultural products inspection were summarized. The prospect of this novel technology in agriculture and food industry was also discussed.

Construction of estuarine tidal-energy barrages has a potentially major effect on the tidal regime of the estuary, particularly upstream of a barrage. Because tidal regime largely controls the distribution and species composition of intertidal plant and animal communities, it is important to understand how barrages may affect such communities. The main objectives of the research described in this report were to relate recent changes in tidal regime within an embanked area of salt marsh and mudflat to changes in the distribution of plant species. This was to test predictions about tidal control of species' range and to assess the site's suitability as an analogue of post-barrage conditions. (author)

Barnoya, Joaquin; Nestle, Marion

2016-12-01

Conflicts of interest arise when corporations marketing harmful products establish financial relationships with research institutions, researchers, or public health organizations. As obesity becomes a worldwide epidemic, such relationships threaten to jeopardize the integrity of scientific research. Latin America, a region undergoing rapid development, is particularly vulnerable to such conflicts. Here, we provide examples of how food and beverage companies are funding nutrition-focused research and institutions in Latin America, putting their credibility at risk. Public health organizations and institutions should take measures to identify, manage, and limit (or eliminate) conflicts of interest caused by partnerships with food companies making and marketing unhealthful products.

Crossing regimes of temperature dependence in animal movement.

Gibert, Jean P; Chelini, Marie-Claire; Rosenthal, Malcolm F; DeLong, John P

2016-05-01

A pressing challenge in ecology is to understand the effects of changing global temperatures on food web structure and dynamics. The stability of these complex ecological networks largely depends on how predator-prey interactions may respond to temperature changes. Because predators and prey rely on their velocities to catch food or avoid being eaten, understanding how temperatures may affect animal movement is central to this quest. Despite our efforts, we still lack a mechanistic understanding of how the effect of temperature on metabolic processes scales up to animal movement and beyond. Here, we merge a biomechanical approach, the Metabolic Theory of Ecology and empirical data to show that animal movement displays multiple regimes of temperature dependence. We also show that crossing these regimes has important consequences for population dynamics and stability, which depend on the parameters controlling predator-prey interactions. We argue that this dependence upon interaction parameters may help explain why experimental work on the temperature dependence of interaction strengths has so far yielded conflicting results. More importantly, these changes in the temperature dependence of animal movement can have consequences that go well beyond ecological interactions and affect, for example, animal communication, mating, sensory detection, and any behavioral modality dependent on the movement of limbs. Finally, by not taking into account the changes in temperature dependence reported here we might not be able to properly forecast the impact of global warming on ecological processes and propose appropriate mitigation action when needed. © 2016 John Wiley & Sons Ltd.

Proper nutrition offers one of the most effective and least costly ways to decrease the burden of many diseases and their associated risk factors, including obesity. Nutrition research holds the key to increasing our understanding of the causes of obesity and its related comorbidities and thus holds promise to markedly influence global health and economies. After outreach to 75 thought leaders, the American Society for Nutrition (ASN) convened a Working Group to identify the nutrition research needs whose advancement will have the greatest projected impact on the future health and well-being of global populations. ASN’s Nutrition Research Needs focus on the following high priority areas: 1) variability in individual responses to diet and foods; 2) healthy growth, development, and reproduction; 3) health maintenance; 4) medical management; 5) nutrition-related behaviors; and 6) food supply/environment. ASN hopes the Nutrition Research Needs will prompt collaboration among scientists across all disciplines to advance this challenging research agenda given the high potential for translation and impact on public health. Furthermore, ASN hopes the findings from the Nutrition Research Needs will stimulate the development and adoption of new and innovative strategies that can be applied toward the prevention and treatment of nutrition-related diseases. The multidisciplinary nature of nutrition research requires stakeholders with differing areas of expertise to collaborate on multifaceted approaches to establish the evidence-based nutrition guidance and policies that will lead to better health for the global population. In addition to the identified research needs, ASN also identified 5 tools that are critical to the advancement of the Nutrition Research Needs: 1) omics, 2) bioinformatics, 3) databases, 4) biomarkers, and 5) cost-effectiveness analysis.

Such techniques offer the potential to enhance global trade by providing an independent means of verifying "paper" traceability systems and can also help to prove authenticity, to combat fraudulent practices, and to control adulteration, which are important issues for economic, religious or cultural reasons. To address some of the challenges that developing countries face in attempting to implement effective food traceability systems, the IAEA, through its Joint FAO/IAEA Division on Nuclear Techniques in Food and Agriculture, has initiated a 5-year coordinated research project involving institutes in 15 developing and developed countries (Austria, Botswana, Chile, China, France, India, Lebanon, Morocco, Portugal, Singapore, Sweden, Thailand, Uganda, UK, USA). The objective is to help in member state laboratories to establish robust analytical techniques and databases, validated to international standards, to determine the provenance of food. Nuclear techniques such as stable isotope and multi-element analysis, along with complementary methods, will be applied for the verification of food traceability systems and claims related to food origin, production, and authenticity. This integrated and multidisciplinary approach to strengthening capacity in food traceability will contribute to the effective implementation of holistic systems for food safety and control. The project focuses mainly on the development of techniques to confirm product authenticity, with several research partners also considering food safety issues. Research topics encompass determination of the geographical origin of a variety of commodities, including seed oils, rice, wine, olive oil, wheat, orange juice, fish, groundnuts, tea, pork, honey and
Summary Authoritarialism as Political Regime: Analysis of Historical and Empirical Studies

Full Text Available This article is devoted to the problems of existence of authoritarian regimes. The ambiguity of the resulting data determines the importance of the considered research. Authoritarianism is quite complicated socio-political phenomenon. For this reason, there are a lot of typologies and special features of authoritarianism as a political regime. Authoritarianism is not only a political regime, but it is also a set of social and political characteristics. Some countries, where the authoritarian tendencies dominate, are economically developed, and they have a competitive economy, but other countries, which are steeped in a reactionary authoritarian, do not develop properly. From the materials of this article it should be concluded that the political regime in Russia is principally authoritarian, or to be specific it is liberal authoritarian regime. This political regime has been established for the whole history of our country, and it is supported by paternalistic political culture and special mindset our nation.
Regime change?

Pilat, Joseph F.; Budlong-Sylvester, K.W.

Following the 1998 nuclear tests in South Asia and later reinforced by revelations about North Korean and Iraqi nuclear activities, there has been growing concern about increasing proliferation dangers. At the same time, the prospects of radiological/nuclear terrorism are seen to be rising - since 9/11, concern over a proliferation/terrorism nexus has never been higher. In the face of this growing danger, there are urgent calls for stronger measures to strengthen the current international nuclear nonproliferation regime, including recommendations to place civilian processing of weapon-useable material under multinational control. As well, there are calls for entirely new tools, including military options. As proliferation and terrorism concerns grow, the regime is under pressure and there is a temptation to consider fundamental changes to the regime. In this context, this paper will address the following: Do we need to change the regime centered on the Treaty on the Nonproliferation of Nuclear Weapons (NPT) and the International Atomic Energy Agency (IAEA)? What improvements could ensure it will be the foundation for the proliferation resistance and physical protection needed if nuclear power grows? What will make it a viable centerpiece of future nonproliferation and counterterrorism approaches?

Developing an agenda for research about policies to improve access to healthy foods in rural communities: a concept mapping study

Science.gov (United States)

2014-01-01

Background Policies that improve access to healthy, affordable foods may improve population health and reduce health disparities. In the United States most food access policy research focuses on urban communities even though residents of rural communities face disproportionately higher risk for nutrition-related chronic diseases compared to residents of urban communities. The purpose of this study was to (1) identify the factors associated with access to healthy, affordable food in rural communities in the United States; and (2) prioritize a meaningful and feasible rural food policy research agenda. Methods This study was conducted by the Rural Food Access Workgroup (RFAWG), a workgroup facilitated by the Nutrition and Obesity Policy Research and Evaluation Network. A national sample of academic and non-academic researchers, public health and cooperative extension practitioners, and other experts who focus on rural food access and economic development was invited to complete a concept mapping process that included brainstorming the factors that are associated with rural food access, sorting and organizing the factors into similar domains, and rating the importance of policies and research to address these factors. As a last step, RFAWG members convened to interpret the data and establish research recommendations. Results Seventy-five participants in the brainstorming exercise represented the following sectors: non-extension research (n = 27), non-extension program administration (n = 18), “other” (n = 14), policy advocacy (n = 10), and cooperative extension service (n = 6). The brainstorming exercise generated 90 distinct statements about factors associated with rural food access in the United States; these were sorted into 5 clusters. Go Zones were established for the factors that were rated highly as both a priority policy target and a priority for research. The highest ranked policy and research priorities include strategies designed to

Between 1948 and 1996, mean annual environmental parameters in the Arctic experienced a well-pronounced decadal variability with two basic circulation patterns: cyclonic and anticyclonic alternating at 5 to 7 year intervals. During cyclonic regimes, low sea-level atmospheric pressure (SLP) dominated over the Arctic Ocean driving sea ice and the upper ocean counterclockwise; the Arctic atmosphere was relatively warm and humid, and freshwater flux from the Arctic Ocean towards the subarctic seas was intensified. By contrast, during anticylonic circulation regimes, high SLP dominated driving sea ice and the upper ocean clockwise. Meanwhile, the atmosphere was cold and dry and the freshwater flux from the Arctic to the subarctic seas was reduced. Since 1997, however, the Arctic system has been under the influence of an anticyclonic circulation regime (17 years) with a set of environmental parameters that are atypical for this regime. We discuss a hypothesis explaining the causes and mechanisms regulating the intensity and duration of Arctic circulation regimes, and speculate how changes in freshwater fluxes from the Arctic Ocean and Greenland impact environmental conditions and interrupt their decadal variability. © 2015 The Authors.

Integrating Food-Water-Energy Research through a Socio-Ecosystem Approach

Directory of Open Access Journals (Sweden)

Manuel Maass

2017-08-01

Full Text Available The nexus approach helps in recognizing the link between water, energy, and food production systems, emphasizing the need to manage them in a more integrated way. The socio-ecosystem (SES approach, however, goes beyond that, by incorporating the regulation and supporting services in the management equation. Changes in ecosystem integrity affect the delivery of ecosystem services to society, which affects local people's well-being, creating a feedback mechanism regarding management strategies. The SES approach makes explicit the “human-bio-physical” nature of our interaction with ecosystems, highlighting the need for a more integrated and interconnected social-ecological research perspective. In addition, the SES approach makes more explicit the multi-scale character of the ecological processes that structure and maintain social-ecological systems. Water dynamics have an important role in shaping ecosystem's structure and functioning, as well as determining the systems capacity for delivering provisioning services. The tropical dry-deciduous forest (TDF, is particularly useful in studying water-food-energy trade-off interactions. Recently, a category 5 hurricane landed in the study area (Mexico's Pacific coast, triggering various social and ecological problems. This event is challenging the current forest management strategies in the region. The extreme hydrometeorological event created an excellent opportunity to test and promote the SES approach for more integrated food-water-energy research. By using the SES approach within our long-term socio-ecological research project, it was easier to identify opportunities for tackling trade-offs between maintaining the transformation of the system and a more sustainable alternative: promoting the maintenance of the ecosystem's integrity and its capacity to deliver provisioning and regulating services.
The impact of food preservation on food waste.

Martindale, Wayne; Schiebel, Walter

2017-01-01

The purpose of this paper is to demonstrate the relationship between food preservation and reducing consumer waste is of value in developing sustainable meal options. The research reports insights into Austrian marketplace for frozen and fresh foods that have been obtained from a consumer survey. The consumer survey methodologies indicate how preservation can change meal planning and lower food waste across frozen and fresh and ambient food purchases using freezing preservation methods. The results show food waste can be reduced by six-fold when frozen foods are compared with fresh foods. This study highlights the requirement for a greater understanding of the probability that specific foods will be wasted with respect to the frequency of purchase. This is a limitation of the current study that has been investigated by other researchers. This research has enabled the identification of different food waste amounts for different food product categories. The data presented could be used to guide food product development so that less consumer waste is produced. The research suggests a decision matrix approach can be used to can guide new product development and a model of this matrix is presented so that it may provide fit-for-purpose food preservation options for consumers. This paper will continue to highlight the overlooked value of food preservation during processing and manufacturing of foods and their preparation in households.
Forthcoming Challenges in Mycotoxins Toxicology Research for Safer Food-A Need for Multi-Omics Approach.

2017-01-04

The presence of mycotoxins in food represents a severe threat for public health and welfare, and poses relevant research challenges in the food toxicology field. Nowadays, food toxicologists have to provide answers to food-related toxicological issues, but at the same time they should provide the appropriate knowledge in background to effectively support the evidence-based decision-making in food safety. Therefore, keeping in mind that regulatory actions should be based on sound scientific findings, the present opinion addresses the main challenges in providing reliable data for supporting the risk assessment of foodborne mycotoxins.

Growth and abundance of Pacific Sand Lance, Ammodytes hexapterus, under differing oceanographic regimes

Robards, Martin D.; Gray, Floyd; Piatt, John F.

2002-01-01

Dramatic changes in seabird and marine mammal stocks in the Gulf of Alaska have been linked to shifts in abundance and composition of forage fish stocks over the past 20 years. The relative value (e.g., size and condition of individual fish, abundance) of specific forage fish stocks to predators under temporally changing oceanographic regimes is also expected to vary. We inferred potential temporal responses in abundance, growth, and age structure of a key forage fish, sand lance, by studying across spatially different oceanographic regimes. Marked meso-scale differences in abundance, growth, and mortality existed in conjunction with these differing regimes. Growth rate within stocks (between years) was positively correlated with temperature. However, this relationship did not exist among stocks (locations) and differing growth rates were better correlated to marine productivity. Sand lance were least abundant and grew slowest at the warmest site (Chisik Island), an area of limited habitat and low food abundance. Abundance and growth of juvenile sand lance was highest at the coolest site (Barren Islands), an area of highly productive upwelled waters. Sand lance at two sites located oceanographically between the Barren Islands and Chisik Island (inner- and outer-Kachemak Bay) displayed correspondingly intermediate abundance and growth. Resident predators at these sites are presented with markedly different numbers and quality of this key prey species. Our results suggest that at the decadal scale, Gulf of Alaska forage fish such as sand lance are probably more profoundly affected by changes in abundance and quality of their planktonic food, than by temperature alone.

Qualitative research in teen experiences living with food-induced anaphylaxis: A meta-aggregation.

To describe the central experiences of teens living with food-induced anaphylaxis as a first step in responding to healthcare needs in this population. As prevalence of allergy increases and commonly outgrown allergies persist longer, chronic management for teens becomes increasingly important. Synthesizing existing research helps to recognize management needs specific to teens with food allergy. Meta-aggregation for qualitative systematic review, to create synthesis for clinical improvement; guided by Joanna Briggs Institute methods and their Qualitative Assessment and Review Instrument. Seven relevant databases were searched for original qualitative research July 2015; 10 studies (published 2007-2015) met inclusion criteria. Both authors undertook critical appraisal, with consensus by discussion. Findings from line-by-line extraction were grouped into categories and syntheses. In studies with mixed populations, we included only teens (age 12-19) with food-induced anaphylaxis. We developed three syntheses from nine categories and 64 subcategories to reflect central experiences of teens with food-induced anaphylaxis, including: (1) defining the allergic self; (2) finding a balance and (3) controlling the uncontrollable. The syntheses encompass importance of allergic identity/understanding, difficulties in coping with burdens of food allergy and reflect the complex risk interactions teens must negotiate in social contexts. There is a need to respect teens as active participants in managing food-induced anaphylaxis, while recognizing that social expectations and a lack of public awareness/safety can dangerously affect one's needs and decisions. This helps broaden how we conceptualize the needs of teens living with food-induced anaphylaxis, informing ongoing care and management. © 2017 John Wiley & Sons Ltd.

In the context of increasing prevalence of overweight and obesity in societies worldwide, enhancing the satiating capacity of foods may help people control their energy intake and weight. This requires an integrated approach between various food-related disciplines. By structuring this approach around the new product development process, this paper aims to present the contours of such an integrative approach by going through the current state of the art around satiety enhancing foods. It portrays actual food choice as the end result of a complex interaction between internal satiety signals, other food benefits, and environmental cues. Three interrelated routes to satiating enhancement are to change the food composition to develop stronger physiological satiation and satiety signals, anticipate and build on smart external stimuli at the moment of purchase and consumption, and improve palatability and acceptance of satiety enhanced foods. Key research challenges in achieving these routes in the field of nutrition, food technology, consumer, marketing, and communication are outlined.

From Risks to Shared Value? Corporate Strategies in Building a Global Water Accounting and Disclosure Regime

Directory of Open Access Journals (Sweden)

Marco A. Daniel

2012-10-01

Full Text Available The current debate on water accounting and accountability among transnational actors such as corporations and NGOs is likely to contribute to the emergence of a global water governance regime. Corporations within the food and beverage sector (F-B are especially vulnerable to water risks; therefore, in this article we analyse motivations and strategies of the major F-B corporations participating in the debate and developing different water accounting, disclosure and risk-assessment tools. Neo-institutionalism and neo-Gramscian regime theory provide the basis for our framework to analyse the discursive, material and organisational corporate water strategies. Findings based on an analysis of the chosen F-B corporations’ sustainability reports and interviews with key informants suggest that the corporations share similar goals and values with regard to the emerging regime. They seek a standardisation that is practical and supportive in improving their water efficiency and communication with stakeholders. This indicates that some harmonisation has taken place over time and new actors have been pursuing the path of the pioneering companies, but the lead corporations are also differentiating their strategies, thus engaging in hegemonic positioning. However, so far the plethora of NGO-driven accountability initiatives and tools has fragmented the field more than 'war of position' amongst the corporations. Furthermore, several companies claim to have proceeded from internal water-risk management to reducing risks throughout their value chains and watersheds. As a result they are 'creating shared value' with stakeholders, and potentially manifesting an emergent paradigm that goes beyond a private regime framework. Nevertheless, in the absence of verification schemes, questions of sustainability and legitimacy of such actions on the ground prevail and remain a topic for further research.

Food irradiation in India has been undertaken for preservation of food for safe consumption, security of food for round the year and export of the food commodities to earn foreign exchange. Therefore, an irradiation plant known as Food Package Irradiator (FPI) was set-up in the year 1967 in BARC. This plant utilizes gamma radiation from "6"0Co source that has a maximum allowable activity of 100 kCi. It is a multipurpose facility where a wide range of products like onion for sprout inhibition to spices for microbial decontamination can be carried out. In short, the design of irradiator has been considered based on obtaining variable throughputs and variable dose rates

Shallow lakes can switch suddenly from a turbid situation with high concentrations of phytoplankton and other suspended solids to a vegetated state with clear water, and vice versa. These alternative stable states may have a substantial impact on the fate of hydrophobic organic compounds (HOCs). Models that are fit to simulate impacts from these complex interactions are scarce. We developed a contaminant fate model which is linked to an ecosystem model (PCLake) for shallow lakes. This integrated model was successful in simulating long-term dynamics (1953-2012) of representative polycyclic aromatic hydrocarbons (PAHs) in the main biotic and abiotic components in a large shallow lake (Chaohu in China), which has undergone regime shifts in this period. Historical records from sediment cores were used to evaluate the model. The model revealed that regime shifts in shallow lakes had a strong impact on the fate of less hydrophobic compounds due to the large storage capacity of macrophytes, which accumulated up to 55.6% of phenanthrene in the clear state. The abrupt disappearance of macrophytes after the regime shift resulted in a sudden change in phenanthrene distribution, as the sediment became the major sink. For more hydrophobic compounds such as benzo(a)pyrene, the modeled impact of the regime shift was negligible for the whole environment, yet large for biotic compartments. This study is the first to provide a full mechanistic analysis of the impact of regime shifts on the fate of PAHs in a real lake ecosystem. Copyright © 2017 Elsevier Ltd. All rights reserved.
Asset allocation and regime switching on Croatian financial market

Full Text Available It has been known for quite some time now that financial markets exhibit changes in regimes over time. A majority of the literature tends to support that financial markets undergo regimes of bull and bear markets. This characteristic should be modeled in a proper way as investors are always interested in beating the market: either by achieving better returns than others, or by minimizing their portfolio risks. There exist many mathematical and statistical models that are used as tools to achieve the mentioned goals. Introducing the regime switching methodology in existing models has proven to be facilitate achieving such goals. Therefore, the objective of this study is to utilize the regime switching methodology on the Croatian financial market to ascertain its usefulness for Croatian investors. Multivariate regime switching and non-switching models were estimated using daily data from the period 2 January 2007 to 31 December 2015. The assumption is that the investor is interested in stock and bond markets. The results from the MGARCH and regime switching MGARCH models are then compared in order to give answers as to whether the respective methodology applied to the Croatian market is useful and how it may benefit investors. Most of the results support the presumption of incorporating this particular methodology in financial modeling for the Croatia markets. This is the first research that applies the regime switching MGARCH methodology in Croatia (including the Balkan region, hence we expect that this will be a significant contribution to existing methodologies in literature.
Alternative pricing regimes in Ontario : exploring the impacts

Legislative goals were recently established in Ontario to promote reliability and quality of electricity service and to ensure that distribution rates for customers remain reasonable. This presentation explored the effect of changing electricity pricing structures on residential customers in Ontario. This study investigated a period between May to December 2005, in the town of Milton, Ontario. Monthly demand was measured for each month, and monthly weighted averages were presented. Residents with electric heating were removed from the sample. Four pricing structure scenarios were examined: (1) flat rates; (2) time-of-use pricing regimes; (3) real time pricing regimes; and (4) critical peak pricing. Average monthly consumption rates for July and August for all 4 scenarios were presented. Results for time-of-use were compared to flat rates, which showed a slight increase in monthly costs. Real time average monthly electricity costs were significantly higher. Time-of-use costs increased by 57 per cent during the periods examined. Real time pricing regimes resulted in a 196 per cent rise in costs. It was concluded that more research must be done to explore the policy implications of pricing regimes and their effect on consumer behaviour. refs., tabs., figs

Economic interventions in the food environment are expected to effectively promote healthier food choices. However, before introducing them on a large scale, it is important to gain insight into the effectiveness of economic interventions and peoples' genuine reactions to price changes. Nonetheless, because of complex implementation issues, studies on price interventions are virtually non-existent. This is especially true for experiments undertaken in a retail setting. We have developed a research tool to study the effects of retail price interventions in a virtual-reality setting: the Virtual Supermarket. This paper aims to inform researchers about the features and utilization of this new software application. The Virtual Supermarket is a Dutch-developed three-dimensional software application in which study participants can shop in a manner comparable to a real supermarket. The tool can be used to study several food pricing and labelling strategies. The application base can be used to build future extensions and could be translated into, for example, an English-language version. The Virtual Supermarket contains a front-end which is seen by the participants, and a back-end that enables researchers to easily manipulate research conditions. The application keeps track of time spent shopping, number of products purchased, shopping budget, total expenditures and answers on configurable questionnaires. All data is digitally stored and automatically sent to a web server. A pilot study among Dutch consumers (n = 66) revealed that the application accurately collected and stored all data. Results from participant feedback revealed that 83% of the respondents considered the Virtual Supermarket easy to understand and 79% found that their virtual grocery purchases resembled their regular groceries. The Virtual Supermarket is an innovative research tool with a great potential to assist in gaining insight into food purchasing behaviour. The application can be obtained via an URL

Background Economic interventions in the food environment are expected to effectively promote healthier food choices. However, before introducing them on a large scale, it is important to gain insight into the effectiveness of economic interventions and peoples' genuine reactions to price changes. Nonetheless, because of complex implementation issues, studies on price interventions are virtually non-existent. This is especially true for experiments undertaken in a retail setting. We have developed a research tool to study the effects of retail price interventions in a virtual-reality setting: the Virtual Supermarket. This paper aims to inform researchers about the features and utilization of this new software application. Results The Virtual Supermarket is a Dutch-developed three-dimensional software application in which study participants can shop in a manner comparable to a real supermarket. The tool can be used to study several food pricing and labelling strategies. The application base can be used to build future extensions and could be translated into, for example, an English-language version. The Virtual Supermarket contains a front-end which is seen by the participants, and a back-end that enables researchers to easily manipulate research conditions.

To describe the research methods for the development of a new open source, cross-platform tool which processes data from the European Prospective Investigation into Cancer and Nutrition Norfolk Food Frequency Questionnaire (EPIC-Norfolk FFQ). A further aim was to compare nutrient and food group values derived from the current tool (FETA, FFQ EPIC Tool for Analysis) with the previously validated but less accessible tool, CAFÉ (Compositional Analyses from Frequency Estimates). The effect of text matching on intake data was also investigated. Cross-sectional analysis of a prospective cohort study-EPIC-Norfolk. East England population (city of Norwich and its surrounding small towns and rural areas). Complete FFQ data from 11 250 men and 13 602 women (mean age 59 years; range 40-79 years). Nutrient and food group intakes derived from FETA and CAFÉ analyses of EPIC-Norfolk FFQ data. Nutrient outputs from FETA and CAFÉ were similar; mean (SD) energy intake from FETA was 9222 kJ (2633) in men, 8113 kJ (2296) in women, compared with CAFÉ intakes of 9175 kJ (2630) in men, 8091 kJ (2298) in women. The majority of differences resulted in one or less quintile change (98.7%). Only mean daily fruit and vegetable food group intakes were higher in women than in men (278 vs 212 and 284 vs 255 g, respectively). Quintile changes were evident for all nutrients, with the exception of alcohol, when text matching was not executed; however, only the cereals food group was affected. FETA produces similar nutrient and food group values to the previously validated CAFÉ but has the advantages of being open source, cross-platform and complete with a data-entry form directly compatible with the software. The tool will facilitate research using the EPIC-Norfolk FFQ, and can be customised for different study populations.

Ivan Ribnikar

2005-06-01

Full Text Available There is a close relationship between a country’s exchange rate regime and monetary arrangement and if we are to examine monetary arrangements then exchange rate regimes must first be analysed. Within the conventional and most widely used classification of exchange rate regimes into rigid and flexible or into polar regimes (hard peg and float on one side, and intermediate regimes on the other there, is a much greater variety among intermediate regimes. A more precise and, as will be seen, more useful classification of exchange rate regimes is the first topic of the paper. The second topic is how exchange rate regimes influence or determine monetary arrangements and monetary policy or monetary policy regimes: monetary autonomy versus monetary nonautonomy and discretion in monetary policy versus commitment in monetary policy. Both topics are important for countries on their path to the EU and the euro area

Full Text Available Food security is chronically guaranteed in Egypt because of the food subsidy policy of the country. However, the increasing Egyptian population is straining the food supply. To study changes in Egyptian food security and future food supply capacity, we analysed the historical grain production, yield per unit, grain-cultivated area, and per capita grain possession of Egypt. The GM (1,1 model of the grey system was used to predict the future population. Thereafter, the result was combined with scenario analysis to forecast the grain possession and population carrying capacity of Egypt under different scenarios. Results show that the increasing population and limitations in cultivated land will strain Egyptian food security. Only in high cultivated areas and high grain yield scenarios before 2020, or in high cultivated areas and mid grain yield scenarios before 2015, can food supply be basically satisfied (assurance rate ≥ 80% under a standard of 400 kg per capita. Population carrying capacity in 2030 is between 51.45 and 89.35 million. Thus, we propose the use of advanced technologies in agriculture and the adjustment of plant structure and cropping systems to improve land utilization efficiency. Furthermore, urbanization and other uses of cultivated land should be strictly controlled to ensure the planting of grains.

Full Text Available The reasons for the sharp increase in food prices means a large number of factors, which include including the development of the biofuels market, the deterioration of soil quality and crop failures, devaluation of the U.S. dollar, increased energy prices, as well as restrictions on exports and imports in several countries. Therefore, the results of the projections show that the trend of volatility of food prices will only increase. Important factor of speculation in the food market, which are considered the reason for the increase in food prices of 2007–2008 when in the opinion of some researchers, there were no major changes in demand and supply, however, the change in food prices has occurred. Thus, the economic behavior of the largest players in the food market became the reason of sudden increase of hungry people in 33 countries around the world, «food riots» and was the cause of the change of political system in some less developed countries. Volatility in food prices as 2008 and 2010 showed that simultaneous sharp increase in prices of basic food is the cause of the political instability in the countries with different type of Federal system. The key factor in the preservation of the existing regime of governance was the presence of food independence, a developed agrarian sector of the economy even in the conditions of insufficient economic development. Thus, history shows that maintaining stable prices in the domestic market for energy and food is a key task of the state.

Brown, Lee E; Palmer, Sheila M; Johnston, Kerrylyn; Holden, Joseph

2015-05-01

Vegetation removal with fire can alter the thermal regime of the land surface, leading to significant changes in biogeochemistry (e.g. carbon cycling) and soil hydrology. In the UK, large expanses of carbon-rich upland environments are managed to encourage increased abundance of red grouse (Lagopus lagopus scotica) by rotational burning of shrub vegetation. To date, though, there has not been any consideration of whether prescribed vegetation burning on peatlands modifies the thermal regime of the soil mass in the years after fire. In this study thermal regime was monitored across 12 burned peatland soil plots over an 18-month period, with the aim of (i) quantifying thermal dynamics between burned plots of different ages (from post burning), and (ii) developing statistical models to determine the magnitude of thermal change caused by vegetation management. Compared to plots burned 15 + years previously, plots recently burned (management effects. Temperatures measured in soil plots burned vegetation regrows. Our findings that prescribed peatland vegetation burning alters soil thermal regime should provide an impetus for further research to understand the consequences of thermal regime change for carbon processing and release, and hydrological processes, in these peatlands.

An independent collaborative approach was developed for stimulating research on high-priority food safety issues. The Fresh Express Produce Safety Research Initiative was launched in 2007 with $2 million in unrestricted funds from industry and independent direction and oversight from a scientific advisory panel consisting of nationally recognized food safety experts from academia and government agencies. The program had two main objectives: (i) to fund rigorous, innovative, and multidisciplinary research addressing the safety of lettuce, spinach, and other leafy greens and (ii) to share research findings as widely and quickly as possible to support the development of advanced safeguards within the fresh-cut produce industry. Sixty-five proposals were submitted in response to a publicly announced request for proposals and were competitively evaluated. Nine research projects were funded to examine underlying factors involved in Escherichia coli O157:H7 contamination of lettuce, spinach, and other leafy greens and potential strategies for preventing the spread of foodborne pathogens. Results of the studies, published in the Journal of Food Protection, help to identify promising directions for future research into potential sources and entry points of contamination and specific factors associated with harvesting, processing, transporting, and storing produce that allow contaminants to persist and proliferate. The program provides a model for leveraging the strengths of industry, academia, and government to address high-priority issues quickly and directly through applied research. This model can be productively extended to other pathogens and other leafy and nonleafy produce.

Because food and poultry industries are demanding an improvement in written communication skills among graduates, research paper writing should be an integral part of a senior undergraduate class. However, scientific writing assignments are often treated as secondary to developing the technical skills of the students. Scientific research paper writing has been emphasized in an undergraduate course on advanced food microbiology taught in the Poultry Science Department at Texas A& M University (College Station, TX). Students' opinions suggest that research paper writing as part of a senior course in Poultry Science provides students with scientific communication skills and useful training for their career, but more emphasis on reading and understanding scientific literature may be required.

Anaerobic digestion has been practically applied in agricultural and industrial waste treatment and recognized as an economical-effective way for food waste disposal. This paper presented an overview on the researches about anaerobic digestion of food waste. Technologies (e.g., pretreatment, co-digestion, inhibition and mitigation, anaerobic digestion systems, etc.) were introduced and evaluated on the basis of bibliometric analysis. Results indicated that ethanol and aerobic prefermentation were novel approaches to enhance substrates hydrolysis and methane yield. With the promotion of resource recovery, more attention should be paid to biorefinery technologies which can produce more useful products toward zero emissions. Furthermore, a technological route for food waste conversion based on anaerobic digestion was proposed. Copyright © 2017 Elsevier Ltd. All rights reserved.
A lumped parameter core dynamics model for MTR type research reactors under natural convection regime

Highlights: ► A model is presented to simulate the reactivity insertion transient in MTR reactors. ► Transient dynamics of IAEA 10 MW MTR type research reactor are evaluated. ► Maximum unprotected reactivity insertion for safe condition is calculated. ► The model predictions are validated with corresponding results in the literature. - Abstract: On the basis of lumped parameter modeling of both the kinetic and thermal–hydraulic effects, a reasonably accurate simplified model has been developed to predict the dynamic response of MTR reactors following to an unprotected reactivity insertion under natural convection regime. By this model the reactor transient behavior at a given initial steady-state can be solved by a set of ordinary differential equations. The model predictions have an acceptable consent with corresponding results of reactivity insertion transients analyzed in the literature. The inherent safety characteristics of MTR research reactors utilizing natural convection is clearly demonstrated by the expanded model. The safety margin of reactor operating is selected ONB condition and thereby the proposed model determines that any slight increase in the value of $0.73 for inserted reactivity will cause the maximum cladding surface temperature to exceed the ONB condition

In vivo bone strain in the mandibular corpus of Sapajus during a range of oral food processing behaviors.

It has been hypothesized that mandibular corpus morphology of primates is related to the material properties of the foods that they chew. However, chewing foods with different material properties is accompanied by low levels of variation in mandibular strain patterns in macaques. We hypothesized that if variation in primate mandible form reflects adaptations to feeding on foods with different material and geometric properties, then this variation will be driven primarily by differences in oral food processing behavior rather than differences in chewing per se. To test this hypothesis, we recorded in vivo bone strain data from the lateral and medial surfaces of the mandibular corpus during complete feeding sequences in three adult male Sapajus as they fed on foods with a range of sizes and material properties. We assessed whether variation in mandibular corpus strain regimes is associated with variation in feeding behaviors and/or chewing on different foods, and we quantified the relative variation in mandibular corpus strain regimes associated with chewing on foods of different material properties versus a range of oral food processing behaviors (incisor, premolar, and molar biting; pulling on incisors; mastication). Feeding behavior had a significant effect on mandibular corpus strain regimes, as did chewing side and the cycle number in a feeding sequence. However, food type had weaker effects and usually only through interaction effects with chewing side and/or cycle type. Strain regimes varied most across different chew sides, then across different behaviors, and lastly between mastication cycles on different foods. Strain magnitudes associated with premolar, molar, and incisor biting were larger than those recorded during mastication. These data suggest that intra- and inter-specific variation in mandible morphology is a trade-off between performance requirements of different oral food processing behaviors and of variation in chewing side, with direct effects

Threats of nuclear terrorism are increasing after 9/11 terrorist attack. Treats include nuclear explosive device (NED) made by terrorist groups, radiological damage caused by a sabotage aiming nuclear facilities, and radiological dispersion device (RDD), which is also called 'dirty bomb'. In 9/11, Al Qaeda planed to cause radiological consequences by the crash of a nuclear power plant and the captured airplane. The evidence of a dirty bomb experiment was found in Afganistan by the UK intelligence agency. Thus, the international communities including the IAEA work substantial efforts. The leaders of 47 nations attended the 2010 nuclear security summit hosted by President Obama, while the next global nuclear summit will be held in Seoul, 2012. Most states established and are maintaining state's nuclear security regime because of the increasing threat and the international obligations. However, each state's nuclear security regime is different and depends on the state's environment. The methodology for the assessment of state's nuclear security regime is necessary to design and implement an efficient nuclear security regime, and to figure out weak points. The IAEA's INPRO project suggests a checklist method for State's nuclear security regime. The IAEA is now researching more quantitative methods cooperatively with several countries including Korea. In this abstract, methodologies to evaluate state's nuclear security regime by risk assessment are addressed
Research of Household Expenditure for Food and Non-Alcoholic Beverages in the Republic of Croatia

Krsto Kero

2011-12-01

Full Text Available The aim of this paper is to investigate household spending by income deciles. Only the most important one among the expenditure categories was considered, food and non-alcoholic beverages. Research and analysis were based on the results of the Questionnaire on Household Expenditure in the Republic of Croatia. Adequate mathematical and statistical models of expenditure for food and non-alcoholic beverages by income deciles were established. The defined models were used in further research to calculate the coefficient of elasticity. The research showed that expenditure for food and non-alcoholic beverages is non-elastic, thus confirming the first Engel’s law. The obtained results can be used in planning household expenditure also in future periods, considering the fact that the model of expenditure by income deciles referring to the period 200 – 2009 was developed. A model for measuring elasticity was constructed as well. It refers to a 10-year period and can be used to forecast future coefficients of elasticity.

Full Text Available The changes in the social structure, the economic crisis, the ageing of the population had an important role in the development of Romania. As a result, Romania must identify other segments and industries in order to rejuvenate the economy of the country. This study focuses on a market niche represented by Halal food products, which are underdeveloped in Romania at this moment. It may represent a potential catalyst for the development of other latent sectors and may consolidate the bilateral relations with the Muslim countries, in conformity with the globalization and the internalization of the global market. The research method used in this study is the thorough analysis of numerous scientific articles and a literature review. It focuses both on the past and the current state of Halal food products and how the development of this market niche can lead to the expansion of other sectors, such as tourism and education.
Developing a framework of gastronomic systems research to unravel drivers of food choice.

Cuevas, Rosa Paula; de Guia, Annalyn; Demont, Matty

2017-10-01

Nutritional and dietary interventions and the introduction of novel food products and ingredients require a thorough understanding of the drivers of food choice, which are embedded in local context and culture. We developed a framework of "gastronomic systems research" (GSR) to understand culture-specific consumer food choice, and contextualise it to a target population of urban, middle- to high-income Filipino consumers to assess the domestic niche market potential of traditional rice varieties in the Philippines. The GSR framework was contextualised through expert elicitation involving chefs and nutritionists, and validated through a consumer survey conducted during a food exposition. Using the GSR framework, we determined indicative rice consumption patterns of the target population and the specific rice quality attributes they require for specific rice-based dishes and rice consumption occasions. The GSR framework also reveals possible entry points for nutritional and dietary interventions and the introduction of novel food products and ingredients. The GSR framework, therefore, has the potential to aid policymakers and food value chain stakeholders in designing culture-sensitive and context-appropriate interventions not only to help consumers improve their diets, but also to help farmers access niche markets for novel food products and ingredients and thereby improve their livelihoods and preserve cultural heritage.
De Facto Exchange Rate Regime Classifications Are Better Than You Think

OpenAIRE

Michael Bleaney; Mo Tian; Lin Yin

2015-01-01

Several de facto exchange rate regime classifications have been widely used in empirical research, but they are known to disagree with one another to a disturbing extent. We dissect the algorithms employed and argue that they can be significantly improved. We implement the improvements, and show that there is a far higher agreement rate between the modified classifications. We conclude that the current pessimism about de facto exchange rate regime classification schemes is unwarranted.

Tooth decay is the most common childhood disease and it disproportionately affects low-income children. The dietary risk factors associated with socioeconomic status (SES), such as food insecurity and fast-food consumption, are poorly understood. To better understand how upstream social factors are related to dietary behaviors by testing the hypothesis that food insecurity mediates the SES-fast-food consumption relationship. A 36-item survey was administered to caregivers of children younger than age 18 years (n=212). The predictor variable was SES, measured by whether the child was insured by Medicaid (no/yes). Food insecurity, the potential dietary mediator, was measured using the six-item US Department of Agriculture Household Food Security Survey (food secure/food insecure without hunger/food insecure with hunger). The outcome variable was whether the household reported eating at a fast-food restaurant ≥2 times a week (no/yes). We used logistic structural equation and mediation models to test our hypothesis. About 63% of children were classified as low SES. Thirty percent of caregivers reported food insecurity (with or without hunger) and 18.6% of households consumed fast food ≥2 times per week. Lower SES was significantly associated with food insecurity (odds ratio [OR] 3.03, 95% CI 1.51 to 6.04; P=0.002), but SES was not related to fast-food consumption (OR 1.94, 95% CI 0.86 to 4.36; P=0.11). Food insecurity was not associated with fast-food consumption (OR 1.76, 95% CI 0.86 to 3.62; P=0.12). The mediation analyses suggest food insecurity does not mediate the relationship between SES and fast-food consumption. However, there are important potential differences in fast-food consumption by SES and food insecurity status. Future dietary research focusing on tooth decay prevention in vulnerable children may need to account for the differential effects of SES on food insecurity and dietary behaviors like fast-food consumption. Studies are needed to further
Adaptation in Collaborative Governance Regimes

Adaptation and the adaptive capacity of human and environmental systems have been of central concern to natural and social science scholars, many of whom characterize and promote the need for collaborative cross-boundary systems that are seen as flexible and adaptive by definition. Researchers who study collaborative governance systems in the public administration, planning and policy literature have paid less attention to adaptive capacity specifically and institutional adaptation in general. This paper bridges the two literatures and finds four common dimensions of capacity, including structural arrangements, leadership, knowledge and learning, and resources. In this paper, we focus on institutional adaptation in the context of collaborative governance regimes and try to clarify and distinguish collaborative capacity from adaptive capacity and their contributions to adaptive action. We posit further that collaborative capacities generate associated adaptive capacities thereby enabling institutional adaptation within collaborative governance regimes. We develop these distinctions and linkages between collaborative and adaptive capacities with the help of an illustrative case study in watershed management within the National Estuary Program.
Strengthening the nuclear non-proliferation regime

Carlson, J.

2003-01-01

Although the nuclear non-proliferation regime has enjoyed considerable success, today the regime has never been under greater threat. Three states have challenged the objectives of the NPT, and there is a technology challenge - the spread of centrifuge enrichment technology and know-how. A major issue confronting the international community is, how to deal with a determined proliferator? Despite this gloomy scenario, however, the non-proliferation regime has considerable strengths - many of which can be developed further. The regime comprises complex interacting and mutually reinforcing elements. At its centre is the NPT - with IAEA safeguards as the Treaty's verification mechanism. Important complementary elements include: restraint in the supply and the acquisition of sensitive technologies; multilateral regimes such as the CTBT and proposed FMCT; various regional and bilateral regimes; the range of security and arms control arrangements outside the nuclear area (including other WMD regimes); and the development of proliferation-resistant technologies. Especially important are political incentives and sanctions in support of non-proliferation objectives. This paper outlines some of the key issues facing the non-proliferation regime
Autonomia e relevância dos regimes The autonomy and relevance of regimes

Full Text Available Teorias institucionalistas na disciplina de relações internacionais usualmente definem regimes como um conjunto de normas e regras formais ou informais que permitem a convergência de expectativas ou a padronização do comportamento de seus participantes em uma determinada área de interesses com o objetivo de resolver problemas de coordenação que tenderiam a resultados não pareto-eficientes. Como estas definições baseadas meramente na "eficiência" dos regimes não parecem suficientes para explicar sua efetividade, o presente artigo propõe uma definição diferente para regimes: a de arranjos políticos que permitem a redistribuição dos ganhos da cooperação pelos participantes em uma determinada área de interesses em um contexto de interdependência. Regimes possuiriam efetividade pela sua autonomia e relevância, ou seja, por possuírem existência objetiva autônoma da de seus participantes e por influenciarem seu comportamento e expectativas de maneiras que não podem ser reduzidas à ação individual de nenhum deles. O artigo inicia-se com uma breve discussão sobre as dificuldades terminológicas associadas ao estudo de regimes e a definição dos conceitos de autonomia e relevância. Em seguida, classifica os diversos autores participantes do debate em duas perspectivas distintas, uma que nega (não-autonomistas e outra que atribui (autonomistas aos regimes autonomia e relevância, e faz uma breve análise dos autores e tradições mais significativos para o debate, aprofundando-se nos autonomistas e nos argumentos que reforçam a hipótese aqui apresentada. Ao final, o artigo propõe uma decomposição analítica dos regimes nos quatro elementos principais que lhes propiciam autonomia e relevância: normatividade, atores, especificidade da área de interesses e interdependência complexa com o contexto.Regimes are defined by institutionalist theories in the discipline of International Relations as formal or informal sets

Radiation processing for safe, shelf-stable and ready-to-eat food. Proceedings of a final research co-ordination meeting

International Nuclear Information System (INIS)

2003-01-01

The increasingly busy lifestyles of populations in many countries have driven the demand for safe, convenient and ready-to-eat food. Traditional food processes such as drying, canning or refrigeration offer a partial solution to this demand as the sensory quality of such food may be significantly affected or the products may be contaminated by pathogenic bacteria during preparation. For developing countries, safe shelf-stable food without the need for refrigeration would offer advantages. In addition, the increasing number of immuno-compromised populations in many countries requires a new approach to food safety to meet their needs. Irradiation offers a potential to enhance microbiological safety and quality of food through shelf-life extension. The benefits of irradiation as a sanitary treatment of many types of food are well known, some of which are applied commercially in several countries. Little data were available, however, on the effect of irradiation on minimally processed food and composite food including prepared meals. A Co-ordinated Research Project (CRP) on the Development of Safe, Shelf-Stable and Ready-to-Eat Food through Radiation Processing therefore was implemented by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture in 1996 to evaluate the role of irradiation for such food. The results were encouraging as irradiation offers promise as a sanitary treatment to ensure microbiological safety and shelf-life extension of several types of food products including pre-cut vegetables and some sous-vide meals, chilled ready-prepared meals, chilled ready-to-eat meat products, food for immuno-compromised patients/populations, sterile meals, ready-to-eat-food of intermediate moisture content.

The potential of food preservation to reduce food waste.

Science.gov (United States)

Martindale, Wayne

2017-02-01

While we state it seems unthinkable to throw away nearly a third of the food we produce, we still continue to overlook that we are all very much part of this problem because we all consume meals. The amount of food wasted clearly has an impact on our view of what we think a sustainable meal is and our research suggests food waste is a universal function that can help us determine the sustainability of diets. Achieving sustainability in food systems depends on the utilisation of both culinary skills and knowledge of how foods make meals. These are overlooked by the current food waste debate that is concerned with communicating the problem with food waste rather than solutions to it. We aim to change this oversight with the research presented here that demonstrates the need to consider the role of food preservation to reduce food waste and the requirement for new marketing terms associated with sustainability actions that can be used to stimulate changes in consumption behaviours. We have chosen frozen food to demonstrate this because our research has shown that the use of frozen foods results in 47 % less household food waste than fresh food categories. This has created a step-change in how we view food consumption and has stimulated consumer movements that act across different products and supply chains to enable the consumption of the sustainable meal.

A systematic review of sub-national food insecurity research in South Africa: Missed opportunities for policy insights

2017-01-01

Food insecurity is an intractable problem in South Africa. The country has a tradition of evidence-based decision making, grounded in the findings of national surveys. However, the rich insights from sub-national surveys remain a largely untapped resource for understandings of the contextual experience of food insecurity. A web-based search identified 169 sub-national food insecurity studies conducted in the post-apartheid period between 1994 and 2014. The systematic review found that the studies used 27 different measures of food insecurity, confounding the comparative analysis of food insecurity at this level. While social grants have brought a measure of poverty relief at household level, unaffordable diets were the root cause of food insecurity. The increasing consumption of cheaper, more available and preferred ‘globalised’ foods with high energy content and low nutritional value lead to overweight and obesity alongside child stunting. Unless a comparable set of indicators is used in such surveys, they are not able to provide comparable information on the scope and scale of the problem. Policy makers should be engaging with researchers to learn from these studies, while researchers need to share this wealth of sub-national study findings with government to strengthen food security planning, monitoring, and evaluation at all levels.

Static converters power supply: transient regimes; Alimentation par convertisseurs statiques: regimes transitoires

Energy Technology Data Exchange (ETDEWEB)

Pasqualini, G. [Ecole Superieure d`Electricite (France)

1997-08-01

Direct current motors, asynchronous and variable speed synchronous motors are generally supplied with static converters. Speed variation is obtained by voltage variation in DC motors and by frequency variation in AC motors. In these conditions, these motors are running continuously in transient regimes: the DC motors current is not direct and the AC motors current is not sinusoidal. This situation leads to pulsing couples in the shaft line and to an increase of Joule effect losses. The aim of this paper is to present the methods of study of the electric motors functioning using the shape of the power voltages given by converters and mathematical models of these machines. The synchronous machines are rapidly described while the asynchronous machines are studied using Ku`s transformation instead of Park`s transformation for simplification. For each type of machine, calculation methods allow to determine their current, additional losses and couple characteristics. The transient regimes considered are those remaining when the motor is running at a constant speed and defined regime (supply voltages are periodical functions of time). These transient regimes are identically reproducing with a frequency which is a multiple of the converters supply frequency. Transient regimes due to functioning changes of the motor, such as resisting couple or power supply frequency variations, are not considered in this study. (J.S.) 9 refs.

Background: The research into bioactive natural products of medicinal plants has a long tradition, but ethnopharmacology as a well-defined field of research has a relatively short history, only dating back 50 years. Aims: With the fast development of this field and its global importance especially in the fast developing economies of Asia it is timely to assess the most influential articles (as measured by citations) and to identify important drivers and research trends in this field. Methods: Scopus was searched to identify relevant articles which were assessed by all three authors. The 100 most cited articles were identified and analyzed. Bibliometric software (VOSviewer) was utilized to supplement the analysis and to generate a term map that visualized the citation patterns of the 100 articles containing different terms. Results: Forty-four of the 100 articles are reviews. On average, each of the 100 articles had 632 citations and since publication was cited 43 times annually. The four core journals were Journal of Ethnopharmacology ( n = 17), Food Chemistry ( n = 7), Life Sciences ( n = 5), and Journal of Agricultural and Food Chemistry ( n = 4). Anti-oxidant effects appeared to be a recurring and highly cited topic, whereas the links into drug discovery and neuropharmacology seemed to be less strong. Numerous medicinal plants and functional foods were the foci of research, and the foci shifted when comparing pre-2000 and post-2000 publications (with the later involving a broader spectrum of plants and foods and a wider range of biological effects). Contributions largely came from Asia, and also from the Americas, Africa, and Oceania, besides Europe. Conclusion: We have identified and analyzed the 100 most-cited articles in ethnopharmacology. Within 50 years the field has gained a profile and while conventionally often linked to "traditional knowledge," drug discovery and some areas of pharmacology, this analysis highlights its emerging importance in the context

Fire regimes of quaking aspen in the Mountain West

Science.gov (United States)

Shinneman, Douglas J.; Baker, William L.; Rogers, Paul C.; Kulakowski, Dominik

2013-01-01

Quaking aspen (Populus tremuloides Michx.) is the most widespread tree species in North America, and it is found throughout much of the Mountain West (MW) across a broad range of bioclimatic regions. Aspen typically regenerates asexually and prolifically after fire, and due to its seral status in many western conifer forests, aspen is often considered dependent upon disturbance for persistence. In many landscapes, historical evidence for post-fire aspen establishment is clear, and following extended fire-free periods senescing or declining aspen overstories sometimes lack adequate regeneration and are succeeding to conifers. However, aspen also forms relatively stable stands that contain little or no evidence of historical fire. In fact, aspen woodlands range from highly fire-dependent, seral communities to relatively stable, self-replacing, non-seral communities that do not require fire for persistence. Given the broad geographic distribution of aspen, fire regimes in these forests likely co-vary spatially with changing community composition, landscape setting, and climate, and temporally with land use and climate – but relatively few studies have explicitly focused on these important spatiotemporal variations. Here we reviewed the literature to summarize aspen fire regimes in the western US and highlight knowledge gaps. We found that only about one-fourth of the 46 research papers assessed for this review could be considered fire history studies (in which mean fire intervals were calculated), and all but one of these were based primarily on data from fire-scarred conifers. Nearly half of the studies reported at least some evidence of persistent aspen in the absence of fire. We also found that large portions of the MW have had little or no aspen fire history research. As a result of this review, we put forth a classification framework for aspen that is defined by key fire regime parameters (fire severity and probability), and that reflects underlying biophysical

Agroecology in Europe: Research, Education, Collective Action Networks, and Alternative Food Systems

Directory of Open Access Journals (Sweden)

Alexander Wezel

2018-04-01

Full Text Available Agroecology is considered with different focus and weight in different parts of the world as a social and political movement, as science, and as practice. Despite its multitude of definitions, agroecology has begun in Europe to develop in different regional, national and continental networks of researchers, practitioners, advocates and movements. However, there is a lack of a comprehensive overview about these different developments and networks. Therefore, this paper attempts to document and provide a mapping of the development of European agroecology in its diverse forms. Through a literature review, interviews, active conference participation, and an extensive internet search we have collected information about the current state and development of agroecology in Europe. Agroecological research and higher education exist more in western and northern Europe, but farm schools and farmer-to-farmer training are also present in other regions. Today a large variety of topics are studied at research institutions. There is an increasing number of bottom-up agroecological initiatives and national or continental networks and movements. Important movements are around food sovereignty, access to land and seeds. Except for France, there are very few concrete policies for agroecology in Europe. Agroecology is increasingly linked to different fields of agri-food systems. This includes Community Supported Agriculture systems, but also agroecological territories, and some examples of labelling products. To amplify agroecology in Europe in the coming years, policy development will be crucial and proponents of agroecology must join forces and work hand-in-hand with the many stakeholders engaged in initiatives to develop more sustainable agriculture and food systems.
Food Peptidomics

Full Text Available The aim of this review is to discuss the definition of food peptidomics and highlight the role of this approach in food and nutrition sciences. Similar to living organisms, food peptidome may be defined as the whole peptide pool present in a food product or raw material. This definition also covers peptides obtained during technological processes and/or storage. The area of interest of food peptidomics covers research concerning the origin of peptidome, its dynamic changes during processing and/or storage, the influence of its presence, the composition and changes in the pool of peptides on the properties of food products or raw materials as well as the methods applied in research into this group of compounds. The area of interests of food peptidomics would include biological activity, functional properties, allergenicity, sensory properties and information on the product or resource authenticity and origin as well as its history and relationships. Research methods applied in food peptidomics, with special emphasis on computational methods, are also summarized.

Research on bimodal particle extinction coefficient during Brownian coagulation and condensation for the entire particle size regime

International Nuclear Information System (INIS)

Tang Hong; Lin Jianzhong

2011-01-01

The extinction coefficient of atmospheric aerosol particles influences the earth’s radiation balance directly or indirectly, and it can be determined by the scattering and absorption characteristics of aerosol particles. The problem of estimating the change of extinction coefficient due to time evolution of bimodal particle size distribution is studied, and two improved methods for calculating the Brownian coagulation coefficient and the condensation growth rate are proposed, respectively. Through the improved method based on Otto kernel, the Brownian coagulation coefficient can be expressed simply in powers of particle volume for the entire particle size regime based on the fitted polynomials of the mean enhancement function. Meanwhile, the improved method based on Fuchs–Sutugin kernel is developed to obtain the condensation growth rate for the entire particle size regime. And then, the change of the overall extinction coefficient of bimodal distributions undergoing Brownian coagulation and condensation can be estimated comprehensively for the entire particle size regime. Simulation experiments indicate that the extinction coefficients obtained with the improved methods coincide fairly well with the true values, which provide a simple, reliable, and general method to estimate the change of extinction coefficient for the entire particle size regime during the bimodal particle dynamic processes.

The Food Marketing Defense Model: Integrating Psychological Research to Protect Youth and Inform Public Policy.

Science.gov (United States)

Harris, Jennifer L; Brownell, Kelly D; Bargh, John A

2009-12-01

Marketing practices that promote calorie-dense, nutrient-poor foods directly to children and adolescents present significant public health risk. Worldwide, calls for government action and industry change to protect young people from the negative effects of food marketing have increased. Current proposals focus on restricting television advertising to children under 12 years old, but current psychological models suggest that much more is required. All forms of marketing pose considerable risk; adolescents are also highly vulnerable; and food marketing may produce far-reaching negative health outcomes. We propose a food marketing defense model that posits four necessary conditions to effectively counter harmful food marketing practices: awareness, understanding, ability and motivation to resist. A new generation of psychological research is needed to examine each of these processes, including the psychological mechanisms through which food marketing affects young people, to identify public policy that will effectively protect them from harmful influence.

Henon, Y.

1985-10-01

The interest in food irradiation in France can best be shown by the number of facilities under construction or in the planning stage. It was made possible through an evolution of the regulations which encouraged food companies to submit petitions. The first commercial applications will deal with dried, dehydrated or frozen products for which clearances were obtained or are in progress. In cooperation with the food industry, studies were carried out on rice flour, herbal teas, caseinates and ingredients such as colors. In the low doses range, interest seems mostly to be sprouting inhibition of garlic and insect control in dried fruits. Several private companies undertook research on directly consumed commodities such as strawberries, cured meats, saurkraut and ground beef

[Pseudoallergic reactions. Intolerance to natural and synthetic food constituents masquerading as food allergy].

Science.gov (United States)

Kurek, M

1996-09-01

Adverse hypersensitivity reactions to natural foods and certain drugs and food additives are mediated by immunological (allergy) or non-immunological mechanisms. Some clinical and physiological similarities have been noted between these allergic and non-allergic reactions. This observation has led to the concept of "pseudoallergic reactions-PAR". PAR can be triggered in various ways such as: interactions with the central or peripherical nervous system, non-specific release of mediators, enzyme inhibition due to hereditary or pharmacologically induced enzyme deficiencies and pharmacological properties of some natural food constituents such as biogenic amines. The prevalence of adverse reactions to food additives has been calculated to be about 0.1%. PAR to food additives occurs frequently in patients suffering from urticaria, asthma and may be accompanied by history of aspirin or NSAI pseudoallergic reactions. The same additives (azo dyes, sulphites, benzoates) are used in various drug formulations and may be responsible for eliciting PAR. In Poland, labelling of food additives, following the "E number system", has been mandatory since 1993. Unfortunately, this satisfactory trend has not yet been applied to drug additives. The diagnosis of PAR to food additives is based on the anamnesis with analysis of the patient's drug and dietary intake. Skin tests and "in vitro" tests are only sporadically informative. In each individual patient, a specific challenge with additives is desirable. Food additives may be tested according to the schedule based on DBPCFC principle. Individually performed exclusion regimes are the principal methods of prevention.

The system as it currently exists is designed for retrieval of documents, either in hard copy or on microfiche, from the technical files of the MSC Food and Nutrition Section by accession number, author, and/or subject. The system could readily be extended to include retrieval by affiliation, report and contract number, and sponsoring agency should the need arise. It can also be easily converted to computerized retrieval. At present the information retrieval system contains nearly 3000 documents which consist of technical papers, contractors' reports, and reprints obtained from the food and nutrition files at MSC, Technical Library, the library at the Texas Medical Center in Houston, the BMI Technical Libraries, Dr. E. B. Truitt at MBI, and the OSU Medical Libraries. Additional work was done to compile 18 selected bibliographies on subjects of immediate interest on the MSC Food and Nutrition Section.
Addressing the Knowledge Gaps in Agroecology and Identifying Guiding Principles for Transforming Conventional Agri-Food Systems

Full Text Available Today’s society faces many challenges when it comes to food production: producing food sustainably, producing enough of it, distributing food, consuming enough calories, consuming too many calories, consuming culturally-appropriate foods, and reducing the amount of food wasted. The distribution of power within the current mainstream agri-food system is dominated by multinational agri-businesses that control the flow of goods and wealth through the system. This hegemony has implemented a regime whose structures reinforce its control. A growing response to the current agri-food regime is the rise of agroecology, in both developed and developing country contexts. This is not a new phenomenon, but it has evolved over time from its Latin American origins. However, agroecology is not a monolithic block and represents many different perceptions of what it means to advance agroecology and ways in which it can help today’s society tackle the crisis of the agri-food system. This paper addresses these sometimes discordant view points, as well as the gaps in our knowledge regarding agroecology in an effort to lay out some guiding principles for how we can move forward in transforming the current agri-food system to achieve sustainability and a more equitable distribution of power and resources.
Critical review of norovirus surrogates in food safety research: rationale for considering volunteer studies.

Science.gov (United States)

Richards, Gary P

2012-03-01

The inability to propagate human norovirus (NoV) or to clearly differentiate infectious from noninfectious virus particles has led to the use of surrogate viruses, like feline calicivirus (FCV) and murine norovirus-1 (MNV), which are propagatable in cell culture. The use of surrogates is predicated on the assumption that they generally mimic the viruses they represent; however, studies are proving this concept invalid. In direct comparisons between FCV and MNV, their susceptibility to temperatures, environmental and food processing conditions, and disinfectants are dramatically different. Differences have also been noted between the inactivation of NoV and its surrogates, thus questioning the validity of surrogates. Considerable research funding is provided globally each year to conduct surrogate studies on NoVs; however, there is little demonstrated benefit derived from these studies in regard to the development of virus inactivation techniques or food processing strategies. Human challenge studies are needed to determine which processing techniques are effective in reducing NoVs in foods. A major obstacle to clinical trials on NoVs is the perception that such trials are too costly and risky, but in reality, there is far more cost and risk in allowing millions of unsuspecting consumers to contract NoV illness each year, when practical interventions are only a few volunteer studies away. A number of clinical trials have been conducted, providing important insights into NoV inactivation. A shift in research priorities from surrogate research to volunteer studies is essential if we are to identify realistic, practical, and scientifically valid processing approaches to improve food safety.

Romani, Simona; Grappi, Silvia; Bagozzi, Richard P; Barone, Ada Maria

2018-02-01

Recent research has started to show the key role of daily food provision practices in affecting household food waste. Building on and extending these previous contributions, the objective of this paper is to investigate how individuals' everyday practices regarding food (e.g., shopping, cooking, eating, etc.) lead to food waste, and how policy makers and the food industry can implement effective strategies to influence such practices and ultimately help consumers reduce food waste. The research performs three Studies; a critical incident qualitative study (Study 1; N = 514) and a quantitative, survey-based study (Study 2; N = 456) to identify and examine relevant food management behaviors associated with domestic waste. Lastly, findings from a field experiment (Study 3; N = 210) suggest that a specific educational intervention, directed at increasing consumers' perceived skills related to food preparation planning behaviors, reduces domestic food waste. Implications of the research for policy makers and the food industry are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.
Detecting spatial regimes in ecosystems | Science Inventory ...

Science.gov (United States)

Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological potential (i.e. potential vegetation), and often fail to account for ongoing changes due to stressors such as land use change and climate change and their effects on plant and animal communities. We use Fisher information, an information theory based method, on both terrestrial and aquatic animal data (US Breeding Bird Survey and marine zooplankton) to identify ecological boundaries, and compare our results to traditional early warning indicators, conventional ecoregion maps, and multivariate analysis such as nMDS (non-metric Multidimensional Scaling) and cluster analysis. We successfully detect spatial regimes and transitions in both terrestrial and aquatic systems using Fisher information. Furthermore, Fisher information provided explicit spatial information about community change that is absent from other multivariate approaches. Our results suggest that defining spatial regimes based on animal communities may better reflect ecological reality than do traditional ecoregion maps, especially in our current era of rapid and unpredictable ecological change. Use an information theory based method to identify ecological boundaries and compare our results to traditional early warning

Full Text Available The influenced flow regimes. The presence and activities ofhumanity influences the uniform environmental system, and in this context, therivers water resources. In concordance with this, the natural runoff regime suffersbigger and deeper changes. The nature of these changes depending on the type anddegree of water uses. The multitude of the use cause different types of influence,whit different quantitative aspects. In the same time, the influences havequalitative connotations, too, regarding to the modifications of the yearly watervolume runoff. So the natural runoff regime is modified. After analyzing thedistribution laws of the monthly runoff, there have been differenced four types ofinfluenced runoff regimes. In the excess type the influenced runoff is bigger thanthe natural, continuously in the whole year. The deficient type is characterized byinverse rapports like the first type, in the whole year. In the sinusoidal type, theinfluenced runoff is smaller than the natural in the period when the water isretained in the lake reservoirs, and in the depletion period the situation inverts. Atthe irregular type the ratio between influenced and natural runoff is changeable ina random meaner monthly. The recognition of the influenced regime and the gradeof influence are necessary in the evaluation and analysis of the usable hydrologicalriver resources, in the flood defence activities, in the complex scheme of thehydrographic basins, in the environment design and so on.
The Impact of the Applied Exchange Rate Regimes on the Internal Balance of Transition Countries

Vujanić Vlado

2017-12-01

Full Text Available One of the key goals of the economic policy makers of every country is to achieve internal and external balance. An unavoidable segment of the analysis concerning the achievement of internal and external balance is certainly the influence of the exchange rate regime applied in a country. European transition countries, despite their similar initial problems and final objectives, applied different exchange rate regimes adapted to the economic circumstances and needs of the country. The paper aims to examine and demonstrate the impact of the applied exchange rate regime on the internal balance of the transition countries. The research encompasses 10 representative transition countries, in the period from 2000-2014. The results of the research, from the aspect of internal balance, confirmed the justification of the application of the floating exchange rate regime in more developed, but not in less-developed, European transition countries. The application of floating exchange rate regimes in less-developed transition countries is associated with a considerably higher average inflation rate, which may be explained by the higher import dependence of lessdeveloped countries and by the consequent transfer of depreciation to price growth.

Abrupt climate-independent fire regime changes

Science.gov (United States)

Pausas, Juli G.; Keeley, Jon E.

2014-01-01

Wildfires have played a determining role in distribution, composition and structure of many ecosystems worldwide and climatic changes are widely considered to be a major driver of future fire regime changes. However, forecasting future climatic change induced impacts on fire regimes will require a clearer understanding of other drivers of abrupt fire regime changes. Here, we focus on evidence from different environmental and temporal settings of fire regimes changes that are not directly attributed to climatic changes. We review key cases of these abrupt fire regime changes at different spatial and temporal scales, including those directly driven (i) by fauna, (ii) by invasive plant species, and (iii) by socio-economic and policy changes. All these drivers might generate non-linear effects of landscape changes in fuel structure; that is, they generate fuel changes that can cross thresholds of landscape continuity, and thus drastically change fire activity. Although climatic changes might contribute to some of these changes, there are also many instances that are not primarily linked to climatic shifts. Understanding the mechanism driving fire regime changes should contribute to our ability to better assess future fire regimes.

A safety analysis code to design a pressurized water reactor and to obtain the licences including entire proprietary rights is under development in domestic research and development project. The purpose and scope of this report is to develop the flow regimes related models for inter-phase friction, wall frictions, wall heat transfer, and inter-phase heat and mass transfer in two-phase three-field equations. In order to choose choose the flow regime criteria, we have investigated various exiting best-estimate T/H codes in this chapter 2. They are the RELAP5-3D, TRAC-M, CATHARE, MARS codes. Around 500 references used in these codes have been collected and reviewed. Also we have investigated eleven papers in detail. In chapter 3, based on the selected flow regimes, the flow regime maps for a gas-liquid flow in horizontal and vertical tubes have decided including the mechanisms of flow regime transition regions. Conclusively, the process will be presented for choosing the best flow regime maps which occur in gas-liquid two-phase flow in horizontal and vertical pipes. We will look forward to decide the constitutive relations based upon the flow regime maps that are determined in this works. The constitutive relations will be used for the code under development
Economic analysis of the CLC/FC regime as an oil pollution prevention instrument

2006-09-01

The aim of this research is to discuss the effectiveness of CLC/IOPC (Civil Liability Convention) liability regime in the field of oil pollution prevention. This study is mainly carried out from a law and economics perspective, although reference is also made to the economic analysis of international environmental agreements. The first two chapters explore the deterrent potential of the international regime in terms of oil spill prevention, from a theoretical and empirical perspective. The analysis of the effectiveness of the regime as such consists in, on the one hand, considering the ability of the international regime to compensate the entire social costs of oil spills (chapter 3) and, on the other hand, to examine the incentives given to operators in maritime oil transport to prevent accidental pollution (chapters 4 and 5). Sixth chapter considers the impacts of the voluntary nature of the international regime on its deterrent potential. The results obtained from this analysis enable to identify several mechanisms by which the deterrent effect of the existing regime could be increased. However, the overall effectiveness of the international regime appears to be limited by several factors that can not be corrected by means of a modification of the CLC and IOPC conventions. (author)

The trophic dynamics of wetland organisms is the basis of assessing wetland structure and function. Stable isotopes of carbon and nitrogen have been widely applied to identify trophic relationships in food source, food composition and food web transport in wetland ecosystem studies. This paper provided an overall review about the current methodology of isotope mixing model and trophic level in wetland ecosystems, and discussed the standards of trophic fractionation and baseline. Moreover, we characterized the typical food sources and isotopic compositions of wetland ecosystems, summarized the food sources in different trophic levels of herbivores, omnivores and carnivores based on stable isotopic analyses. We also discussed the limitations of stable isotopes in tra-cing food sources and in constructing food webs. Based on the current results, development trends and upcoming requirements, future studies should focus on sample treatment, conservation and trophic enrichment measurement in the wetland food web, as well as on combing a variety of methodologies including traditional stomach stuffing, molecular markers, and multiple isotopes.

Staats, Stefanie; Lüersen, Kai; Wagner, Anika E; Rimbach, Gerald

2018-04-18

Drosophila melanogaster has been widely used in the biological sciences as a model organism. Drosophila has a relatively short life span of 60-80 days, which makes it attractive for life span studies. Moreover, approximately 60% of the fruit fly genes are orthologs to mammals. Thus, metabolic and signal transduction pathways are highly conserved. Maintenance and reproduction of Drosophila do not require sophisticated equipment and are rather cheap. Furthermore, there are fewer ethical issues involved in experimental Drosophila research compared with studies in laboratory rodents, such as rats and mice. Drosophila is increasingly recognized as a model organism in food and nutrition research. Drosophila is often fed complex solid diets based on yeast, corn, and agar. There are also so-called holidic diets available that are defined in terms of their amino acid, fatty acid, carbohydrate, vitamin, mineral, and trace element compositions. Feed intake, body composition, locomotor activity, intestinal barrier function, microbiota, cognition, fertility, aging, and life span can be systematically determined in Drosophila in response to dietary factors. Furthermore, diet-induced pathophysiological mechanisms including inflammation and stress responses may be evaluated in the fly under defined experimental conditions. Here, we critically evaluate Drosophila melanogaster as a versatile model organism in experimental food and nutrition research, review the corresponding data in the literature, and make suggestions for future directions of research.
ANALYSING PERFORMANCE ASSESSMENT IN PUBLIC SERVICES: HOW USEFUL IS THE CONCEPT OF A PERFORMANCE REGIME?

Science.gov (United States)

Martin, Steve; Nutley, Sandra; Downe, James; Grace, Clive

2016-03-01

Approaches to performance assessment have been described as 'performance regimes', but there has been little analysis of what is meant by this concept and whether it has any real value. We draw on four perspectives on regimes - 'institutions and instruments', 'risk regulation regimes', 'internal logics and effects' and 'analytics of government' - to explore how the concept of a multi-dimensional regime can be applied to performance assessment in public services. We conclude that the concept is valuable. It helps to frame comparative and longitudinal analyses of approaches to performance assessment and draws attention to the ways in which public service performance regimes operate at different levels, how they change over time and what drives their development. Areas for future research include analysis of the impacts of performance regimes and interactions between their visible features (such as inspections, performance indicators and star ratings) and the veiled rationalities which underpin them.

For a particular community, what energy-related innovations constitute no-regrets strategies? We present a methodology to understand how alternative energy consuming activities and policy regimes impact on current and future liveability of socio-culturally diverse communities facing climate change. Our methodology augments the energy policy literature by harnessing three concepts (collaborative governance, innovation and political economic regime of provisioning) to support dialogue around changing energy-related activities. We convened workshops in Alice Springs, Australia to build capability to identify no-regrets energy-related housing or transport activities and strategies. In preparation, we interviewed policy actors and constructed three new housing-related future scenarios. After discussing the scenarios, policy and research actors prioritised five socio-technical activities or strategies. Evaluations indicate participants enjoyed opportunities given by the methodology to have focussed discussions about activities and innovation, while requesting more socially nuanced scenario storylines. We discuss implications for theory and technique development. - Highlights: •Energy-related activities and regimes frustrate pro-sustainability action. •Participatory workshops increased understanding of activities and regimes. •Workshops used a novel combination of governance and social theories. •Results justify inclusive dialogue around building energy standards and transport options.
Finite Time Blowup in a Realistic Food-Chain Model

KAUST Repository

Parshad, Rana; Ait Abderrahmane, Hamid; Upadhyay, Ranjit Kumar; Kumari, Nitu

2013-01-01

We investigate a realistic three-species food-chain model, with generalist top predator. The model based on a modified version of the Leslie-Gower scheme incorporates mutual interference in all the three populations and generalizes several other known models in the ecological literature. We show that the model exhibits finite time blowup in certain parameter range and for large enough initial data. This result implies that finite time blowup is possible in a large class of such three-species food-chain models. We propose a modification to the model and prove that the modified model has globally existing classical solutions, as well as a global attractor. We reconstruct the attractor using nonlinear time series analysis and show that it pssesses rich dynamics, including chaos in certain parameter regime, whilst avoiding blowup in any parameter regime. We also provide estimates on its fractal dimension as well as provide numerical simulations to visualise the spatiotemporal chaos.

Currently, food allergy is considered to be one of the diseases of civilization, which occurs as a result of the changing conditions of life and environmental changes (e.g. increased popularity of cesarean delivery, excessive hygienic regime during the neonatal-infantile period). Based on medical statistics, it can be concluded that this problem will be intensified. Consumption of food is one of the main activities in human life. What and how one eats affects our health. Meals eaten regularly provide the components necessary for the energy metabolism. Multicultural society, travel, and new trends affect the diversity of food consumed. The mechanism of food allergy reaction covers all 4 types of the immune response of the classical division of Gell and Coombs. The percentage of the immune response was assessed by Chandra as follows: type I - 48%, type II - 6%, type III - 10%, and type IV - 18%. The article presents the risk factors for food allergy, most common symptoms, preventive measures and characteristics of food products that are potential allergens.

Harris, Jennifer L; Graff, Samantha K

2012-02-01

In the United States, one third of children and adolescents are overweight or obese, yet food and beverage companies continue to target them with advertising for products that contribute to this obesity crisis. When government restrictions on such advertising are proposed, the constitutional commercial speech doctrine is often invoked as a barrier to action. We explore incongruities between the legal justifications for the commercial speech doctrine and the psychological research on how food advertising affects young people. A proper interpretation of the First Amendment should leave room for regulations to protect young people from advertising featuring calorie-dense, nutrient-poor foods and beverages.
The trade regime and the climate regime. Institutional evolution and adaptation

International Nuclear Information System (INIS)

Brewer, Thomas L.

2003-01-01

This article addresses concerns that the multilateral trade regime centered in the WTO and the emerging climate regime may conflict in ways that could be damaging to either or both. The article discusses the institutional and diplomatic context of these concerns, and it identifies the kinds of issues that are in question. The analysis suggests that there are opportunities for win-win outcomes in the interactions of the two regimes, for instance in the possibility of reducing fossil fuel subsidies. However, there are also problematic areas where they intersect. A core issue-and as yet an unresolved one-is whether and how emission credit trading and other activities envisioned by the Kyoto Protocol would be subject to WTO rules. The resolution of this issue will affect many other issues as well. Additional specific issues about the interactions of particular provisions in WTO agreements and the Kyoto Protocol are analyzed in a subsequent companion article in Climate Policy
Risky rays for an improved food supply? National and transnational food irradiation research as a cold war recipe

International Nuclear Information System (INIS)

Zachmann, Karin

2013-01-01

This paper has dealt with an innovation that first emerged as a radiation-employing experimental system roughly by the 1930s. Within the context of World War II and especially in the first decade of the Cold War, protagonists of the nuclear establishment (the military, governmental officials such as representatives of US Atomic Energy Commissions and other national agencies, science managers, researchers, and others) became interested in these experimental systems and their elements - e.g., radioisotopes or ionizing rays that were used to explore processes of life - not primarily in their capacity to produce new ways of knowing, but because of their potential to yield new ways of doing. Therefore, these protagonists pushed the experimental systems into the world outside the laboratory at an early stage of their development. What at first emerged out of scientific curiosity to learn how ionizing rays would influence living matter was quickly employed to serve political purposes under the circumstances of the Cold War. This happened when, e.g., ionizing rays of such radiation employing experimental systems were applied to agriculture and food in order to prove that the atom could be put to peaceful use. Such applications of methods and techniques from experimental systems developed into powerful hybrids of science, technology and politics that decisively determined the global distribution of knowledge and control in and beyond the Cold War era. These hybrids still exist, even though the Cold War ended two decades ago. They exist as projects to introduce high-dose irradiation to ready-made food in order to serve the need of food industries and food retailers to increase turnover and profits. So far, only attentive representatives of consumers have challenged these projects via the mobilization of counter-expertise to the food-safety promises of the Joint FAO/IAEA Division and the Codex Alimentarius Commission. The fight over the safety of irradiated food, ironically

This paper has dealt with an innovation that first emerged as a radiation-employing experimental system roughly by the 1930s. Within the context of World War II and especially in the first decade of the Cold War, protagonists of the nuclear establishment (the military, governmental officials such as representatives of US Atomic Energy Commissions and other national agencies, science managers, researchers, and others) became interested in these experimental systems and their elements - e.g., radioisotopes or ionizing rays that were used to explore processes of life - not primarily in their capacity to produce new ways of knowing, but because of their potential to yield new ways of doing. Therefore, these protagonists pushed the experimental systems into the world outside the laboratory at an early stage of their development. What at first emerged out of scientific curiosity to learn how ionizing rays would influence living matter was quickly employed to serve political purposes under the circumstances of the Cold War. This happened when, e.g., ionizing rays of such radiation employing experimental systems were applied to agriculture and food in order to prove that the atom could be put to peaceful use. Such applications of methods and techniques from experimental systems developed into powerful hybrids of science, technology and politics that decisively determined the global distribution of knowledge and control in and beyond the Cold War era. These hybrids still exist, even though the Cold War ended two decades ago. They exist as projects to introduce high-dose irradiation to ready-made food in order to serve the need of food industries and food retailers to increase turnover and profits. So far, only attentive representatives of consumers have challenged these projects via the mobilization of counter-expertise to the food-safety promises of the Joint FAO/IAEA Division and the Codex Alimentarius Commission.

Due to the rise of consumer's awareness of fresh foods to health, in the past few years, the consumption of fresh and fresh-cut produces has increased sturdily. Modified atmosphere packaging (MAP) possesses a potential to become one of the most appropriate technologies for packaging fresh and fresh-cut produces. The MAP has advantages of extending the shelf-life, preserving or stabilizing the desired properties of fresh produces, and convenience in handing and distribution. The success of MAP-fresh foods depends on many factors including types of fresh foods, storage temperature and humidity, gas composition, and the characteristics of package materials. This paper reviews the recent developments highlighting the most critical factors of film and gas on the quality of MAP fresh foods. Although the innovations and development of food packaging technology will continue to promote the development of novel MAP, concentrated research and endeavors from scientists and engineers are still important to the development of MAP that focuses on consumers' requirements, enhancing product quality, environmental friendly design, and cost-effective application.

The effect of domestic preparation regimes on the level of the heat-formed toxicant furan was studied to provide useful information for exposure assessment and advice for manufacturers and consumers. Foods were cooked in a saucepan on a gas hob or microwaved and furan was determined by headspace sampling with gas chromatography-mass spectrometry. In general, furan levels did not decrease as much when foods were cooked in a microwave oven when compared with the same foods cooked in a saucepan. Furan levels decreased in most canned and jarred foods after heating in a saucepan. Low levels of furan in soups in cartons were not changed by any procedure. Furan decreased slightly in foods on standing before consumption, but did so more rapidly on stirring. The levels also decreased slightly when foods were left to stand on plates; this observation is attributed to the volatility of furan.
Synergies between nonproliferation regimes: A pragmatic approach

Full text: With the recent progress in establishing international nonproliferation regimes, the question of synergies between different verification and monitoring regimes is becoming more acute. Three multilateral and universal nonproliferation organisations covering safeguards on civil nuclear materials, nuclear testing, and chemical weapons are up and running. A regime on biological weapons is under negotiation. Several regional organisations concerned with monitoring nonproliferation commitments in the nuclear field are in place; others are being established. Past discussions on synergies between these regimes have suffered from being too far-reaching. These discussions often have not reflected adequately the political difficulties of cooperation between regimes with different membership, scope and institutional set-up. This paper takes a pragmatic look at exploiting synergies and identifies some potential and real overlaps in the work between different verification regimes. It argues for a bottom-up approach and identifies building blocks for collaboration between verification regimes. By realising such, more limited potential for cooperation, the ground could be prepared for exploiting other synergies between these regimes. (author)

The aim of this paper is to present a paradigm shift from meat demand to health driven understanding of the effects of livestock production and meat consumption in human. Included are comments on animal nutrition research with the purpose of getting more relevant health information. The growth and metabolism research covers the principles from feed intake regulation, nutrient digestion, absorption and growth. Meat preservation provides enough food for the urban population, and its major ingredient includes the combination of salt, sugar and fats, suspected to cause food addiction in man. The reported effect of processed red meat causing systemic inflammation is a major consideration in food preparation, diet selection and reasonable control for meat consumption. In livestock “Pharming” the danger of heavy metal contamination of commercial feed poses threat to human health aside from drug residues. It is proposed that the 50% of global greenhouse gas is due to the lifestyle of the rich and epidemic of obesity-related diseases are the effect of livestock “Pharming” and addiction to fast food and or processed meat.

Full Text Available Definition of preparatory parameters for sterilization regime of canned "Natural Atlantic Mackerel with Oil" is the aim of current study. PRSC software developed at the department of automation and computer engineering is used for preparatory selection. To determine the parameters of process model, in laboratory autoclave AVK-30M the pre-trial process of sterilization and cooling in water with backpressure of canned "Natural Atlantic Mackerel with Oil" in can N 3 has been performed. Gathering information about the temperature in the autoclave sterilization chamber and the can with product has been carried out using Ellab TrackSense PRO loggers. Due to the obtained information three transfer functions for the product model have been identified: in the least heated area of autoclave, the average heated and the most heated. In PRSC programme temporary temperature dependences in the sterilization chamber have been built using this information. The model of sterilization process of canned "Natural Atlantic Mackerel with Oil" has been received after the pre-trial process. Then in the automatic mode the sterilization regime of canned "Natural Atlantic Mackerel with Oil" has been selected using the value of actual effect close to normative sterilizing effect (5.9 conditional minutes. Furthermore, in this study step-mode sterilization of canned "Natural Atlantic Mackerel with Oil" has been selected. Utilization of step-mode sterilization with the maximum temperature equal to 125 °C in the sterilization chamber allows reduce process duration by 10 %. However, the application of this regime in practice requires additional research. Using the described approach based on the developed mathematical models of the process allows receive optimal step and variable canned food sterilization regimes with high energy efficiency and product quality.

Background Tooth decay is the most common childhood disease and disproportionately affects low-income children. The dietary risk factors associated with socioeconomic status (SES), such as food insecurity and fast food consumption, are poorly understood. Objective To better understand how upstream social factors are related to dietary behaviors by testing the hypothesis that food insecurity mediates the SES-fast food consumption relationship. Design A 36-item survey was administered to caregivers of children Food insecurity, the potential dietary mediator, was measured using the six-item U.S. Department of Agriculture Household Food Security Survey (food secure/food insecure without hunger/food insecure with hunger). The outcome variable was whether the household reported eating at a fast food restaurant ≥2 times a week (no/yes). We used logistic structural equation and mediation models to test our hypothesis. Results About 63% of children were low SES. Thirty-percent of caregivers reported food insecurity (with or without hunger) and 18.6% of households consumed fast food ≥2 times per week. Lower SES was significantly associated with food insecurity (OR=3.03; 95% CI=1.51, 6.04; P=0.002), but SES was not related to fast food consumption (OR=1.94; 95% CI=0.86, 4.36; P=0.11). Food insecurity was not associated with fast food consumption (OR=1.76; 95% CI=0.86, 3.62; P=0.12). The mediation analyses suggest food insecurity does not mediate the relationship between SES and fast food consumption. However, there are important potential differences in fast food consumption by SES and food insecurity status. Conclusions Future dietary research focusing on tooth decay prevention in vulnerable children may need to account for the differential effects of SES on food insecurity and dietary behaviors like fast food consumption. Studies are needed to further elucidate the mechanisms linking SES, dietary behaviors, and tooth decay in children. PMID:25840937

Rice barns have been developed in some areas in Central Java, but several problems seem to appear, leading to nonoptimal functions of nonactive food barns. The present article aims to examine revitalization of food barns through systematic, integrated, and sustainable empowerment. The research design is exploratory research to generate data that are in-depth qualitative and quantitative. Survey was applied in four regencies including Wonogiri, Purworejo, Temanggung, and Batang. Key informants comprise caretakers of food barns, village apparatus, public figures, and Food Security Office apparatus. The research results revealed that the food barns have not been managed in professional manners. Active roles of all members and caretakers, village government, and Food Security Agency are, therefore, required in revitalizing the food barns. In order to perform social functions well, the food barns should be profit-oriented to achieve sustainability.
Charity Starts … at Work? Conceptual Foundations for Research with Businesses that Donate to Food Redistribution Organisations

Elisha Vlaholias

2015-06-01

Full Text Available As global concern about sustainability, food waste, and poverty increases, there is an urgent need to understand what motivates businesses to adopt pro-social and pro-environmental behaviours. This paper suggests that food redistribution organisations hold both pro-social and pro-environmental aims, due to their concern with reducing food surplus and food insecurity. To achieve this, they must motivate food businesses to donate their surplus food. However, little is known about the values, attitudes, and motives of food industry donors. The purpose of this paper is to provide a theoretical and conceptual overview to set out principles from which empirical data on food redistribution will be analysed or critiqued. Specifically, it explores pro-social and pro-environmental literature, as these fields have examined the motivations behind donations and reducing environmental impact. This review highlights that charitable giving of food is different to other inorganic material, such as money. Thus, future research is needed to capture the unique temporal, emotional, social, and environmental factors that motivate food donations. This information may contribute to the development of strategies that target and motivate people from the food industry to become food donors. Alternatively, it may reveal concerns about food donations, and highlight the need for other approaches to food waste and food insecurity.

The potential application of European market research data in dietary exposure modelling of food additives.

Tennant, David Robin; Bruyninckx, Chris

2018-03-01

Consumer exposure assessments for food additives are incomplete without information about the proportions of foods in each authorised category that contain the additive. Such information has been difficult to obtain but the Mintel Global New Products Database (GNPD) provides information about product launches across Europe over the past 20 years. These data can be searched to identify products with specific additives listed on product labels and the numbers compared with total product launches for food and drink categories in the same database to determine the frequency of occurrence. There are uncertainties associated with the data but these can be managed by adopting a cautious and conservative approach. GNPD data can be mapped with authorised food categories and with food descriptions used in the EFSA Comprehensive European Food Consumption Surveys Database for exposure modelling. The data, when presented as percent occurrence, could be incorporated into the EFSA ANS Panel's 'brand-loyal/non-brand loyal exposure model in a quantitative way. Case studies of preservative, antioxidant, colour and sweetener additives showed that the impact of including occurrence data is greatest in the non-brand loyal scenario. Recommendations for future research include identifying occurrence data for alcoholic beverages, linking regulatory food codes, FoodEx and GNPD product descriptions, developing the use of occurrence data for carry-over foods and improving understanding of brand loyalty in consumer exposure models.

Full Text Available Foodborne illness has a substantial health and economic burden on society, and most cases are believed to be due to unsafe food handling practices at home. Several qualitative research studies have been conducted to investigate consumers' perspectives, opinions, and experiences with safe food handling at home, and these studies provide insights into the underlying barriers and facilitators affecting their safe food handling behaviours. We conducted a systematic review of previously published qualitative studies in this area to synthesize the main across-study themes and to develop recommendations for future consumer interventions and research. The review was conducted using the following steps: comprehensive search strategy; relevance screening of abstracts; relevance confirmation of articles; study quality assessment; thematic synthesis of the results; and quality-of-evidence assessment. A total of 39 relevant articles reporting on 37 unique qualitative studies were identified. Twenty-one barriers and 10 facilitators to safe food handling were identified, grouped across six descriptive themes: confidence and perceived risk; knowledge-behaviour gap; habits and heuristics; practical and lifestyle constraints; food preferences; and societal and social influences. Our overall confidence that each barrier and facilitator represents the phenomenon of interest was rated as high (n = 11, moderate (11, and low (9. Overarching analytical themes included: 1 safe food handling behaviours occur as part of a complex interaction of everyday consumer practices and habituation; 2 most consumers are not concerned about food safety and are generally not motivated to change their behaviours based on new knowledge about food safety risks; and 3 consumers are amenable to changing their safe food handling habits through relevant social pressures. Key implications and recommendations for research, policy and practice are discussed.

Two-phase flow shows various flow patterns according to the amount of the void and its relative velocity to the liquid flow. This variation directly affect the interfacial transfer which is the key factor for the design or analysis of the phase change systems. Especially the safety analysis of the nuclear power plant has been performed based on the numerical code furnished with the proper constitutive relations depending highly upon the flow regimes. Heavy efforts have been focused to identify the flow regime and at this moment we stand on relative very stable engineering background compare to the other research field. However, the issues related to objectiveness and transient flow regime are still open to study. Lee et al. and Ishii developed the method for the objective and instantaneous flow regime identification based on the neural network and new index of probability distribution of the flow regime which allows just one second observation for the flow regime identification. In the present paper, we developed the self-organized neural network for more objective approach to this problem. Kohonen's Self-Organizing Map (SOM) has been used for clustering, visualization, and abstraction. The SOM is trained through unsupervised competitive learning using a 'winner takes it all' policy. Therefore, its unsupervised training character delete the possible interference of the regime developer to the neural network training. After developing the computer code, we evaluate the performance of the code with the vertically upward two-phase flow in the pipes of 25.4 and 50.4 cmm I.D. Also, the sensitivity of the number of the clusters to the flow regime identification was made

Understanding the Relationship Between Food Variety, Food Intake, and Energy Balance.

Science.gov (United States)

Raynor, Hollie A; Vadiveloo, Maya

2018-03-01

In accordance with US dietary guidance, incorporating variety into the diet can align with energy balance, though greater food variety in some categories may make energy balance more challenging. Thus, experimental and epidemiologic evidence is summarized on the relationship between food variety, food and energy intake, and energy balance. Lab-based, experimental research consistently demonstrates that greater variety within foods or sensory characteristics of food increases food and energy intake within an eating occasion. Epidemiologic evidence is less consistent, potentially driven by differing methodologies, particularly in defining and measuring food variety. Moreover, the effect of variety on energy balance appears to be moderated by food energy density. Integrating insights from experimental and epidemiologic research are essential for strengthening food variety guidance including developing evidence-based definitions of food variety, understanding moderators of the relationship, and developing practical guidance interpretable to consumers.

In the United States, one third of children and adolescents are overweight or obese, yet food and beverage companies continue to target them with advertising for products that contribute to this obesity crisis. When government restrictions on such advertising are proposed, the constitutional commercial speech doctrine is often invoked as a barrier to action. We explore incongruities between the legal justifications for the commercial speech doctrine and the psychological research on how food advertising affects young people. A proper interpretation of the First Amendment should leave room for regulations to protect young people from advertising featuring calorie-dense, nutrient-poor foods and beverages. PMID:22390435

Full Text Available The climate regime addresses one of the most important challenges facing humankind today. However, while the environmental and economic sides of the problem are well represented, it lacks the inclusion of social and human aspects. The human rights regime, in contrast, is a regime which has been established precisely to implement human values. This article ex-plains the problems of climate change in terms of human values and argues that some proce-dures from the human rights regime offer possibilities for improvement. It is submitted that through the inclusion of human rights instruments, such as individual communication, pro-gressive realisation and authoritative interpretation, the inclusion of human values into the climate regime will be facilitated. This article presents these instruments and discusses their potential for inclusion in the climate regime.
Novel concepts on functional foods and nutrigenomics in healthy aging and chronic diseases: a review of fermented papaya preparation research progress

2012-05-01

Full Text Available AbstractFunctional foods are an emerging research field corresponding with genomical, epidemiological and clinical studies integrated with the food industry in accordance with the consumer demands. Consequently, the features of the functional foods are being discussed by various researchers and related institutions, and a common view has been pointed out about the availability and the nature of the components of functional foods. Recently, the outcomes of functional foods are being assessed by the help of all the available scientific tools. Genomic medicine is one of the most promising areas of research to reveal the benefits of functional foods and the bioactive ingredients. Nutrigenomics aims at studying the genetic and epigenetic interactions with a nutrient or the functional component in order to lead to a phenotype change and therefore to the cell metabolism, differentiation or even apoptosis. Papaya and its fermentation product arespecific products derived from the technologically advanced and controlled environmentalfriendly bio-fermentation process. Functional Foods in Health and Disease 2012, 2(5:120-136 It has been well known for a long time that the natural anti-oxidant properties of papaya, mainly depending on vitamins A and C in addition to certain amino acids, were consistent both in the fruit and derived from the papain enzyme which is no longer present in the fermented product. In this article, functional foods in genomic medicine are discussed in review of the fermented papaya preparation research progress. Clinical evidences about fermented papaya as a functional food are reported as supported by various research protocols and experimental models. The benefits of fermented papaya preparation are also discussed in nutrigenomic basis and it is reported to have an important antioxidant and transcriptomic potential which deserves further investigation. As a conclusion, fermented papaya preparation represents a Functional Food

This publication covers the activities and accomplishments of eight countries that participated in a Co-ordinated Research Project (CRP) on Public Acceptance and Market Development of Irradiated Food in Asia and the Pacific, as presented at a final Research Coordination Meeting held in Bangkok, 20-25 September 1998. The CRP was implemented through research agreements with Bangladesh, China (one each for Shanghai and Beijing), the Republic of Korea, Malaysia, Pakistan, the Philippines, Sri Lanka, Thailand and Viet Nam, from 1994 to 1998. The technical work undertaken to bring food irradiation technology to the marketplace to address food security, public health and trade needs, is described. This covered the establishment of quality assurance procedures, the determination of irradiation doses for nontraditional as well as traditional foods, the conduct of techno-economic feasibility, and the identification of industry and consumer needs. In the majority of cases, R and D activities were undertaken in partnership with industry. Developments in the establishment and harmonization of regulations on food irradiation were also monitored. The participants made commendable progress in the marketing of irradiated food and in the understanding and promotion of consumer acceptance of the technology. This was demonstrated in the marketing of close to 179,000 tons of different food and related products through normal trading channels. While the volume of food irradiated varied with the capacity of irradiation plants in participating countries, the work showed that consumers would accept irradiated foods and that trade benefits would ensue from the application of the technology. Information dissemination was found to be a critical factor in public acceptance.

'CANDLE' burnup regime after LWR regime

International Nuclear Information System (INIS)

Sekimoto, Hiroshi; Nagata, Akito

2008-01-01

CANDLE (Constant Axial shape of Neutron flux, nuclide densities and power shape During Life of Energy producing reactor) burnup strategy can derive many merits. From safety point of view, the change of excess reactivity along burnup is theoretically zero, and the core characteristics, such as power feedback coefficients and power peaking factor, are not changed along burnup. Application of this burnup strategy to neutron rich fast reactors makes excellent performances. Only natural or depleted uranium is required for the replacing fuels. About 40% of natural or depleted uranium undergoes fission without the conventional reprocessing and enrichment. If the LWR produced energy of X Joules, the CANDLE reactor can produce about 50X Joules from the depleted uranium left at the enrichment facility for the LWR fuel. If we can say LWRs have produced energy sufficient for full 20 years, we can produce the energy for 1000 years by using the CANDLE reactors with depleted uranium. We need not mine any uranium ore, and do not need reprocessing facility. The burnup of spent fuel becomes 10 times. Therefore, the spent fuel amount per produced energy is also reduced to one-tenth. The details of the scenario of CANDLE burnup regime after LWR regime will be presented at the symposium. (author)
Research of consumers’ attitudes on the organic food consumption in the Serbian enclaves in Kosovo

Full Text Available The organic production in Serbian enclaves in Kosovo has a great potential based on the extensive production mostly in hilly-mountainous areas with rich and convenient environment for the organic production of medicinal plants, fruits, vegetables, wine, honey etc., but it still keeps developing. The enclave can realise a high income, and thereby also an economic basis for the sustainable development of multifunctional agricultural holdings in Serbian enclaves, by the production and sale of organic products on local markets. In this paper, the authors study the consumers’ attitudes on purchase and consumption of organic food in Serbian enclaves in Kosovo. Empirical research was carried out on a spatial sample of 300 respondents, by a personal communication technique using the questionnaire as an instrument of research method. Areas of research are towns: Northern Kosovska Mitrovica, Leposavic, Zubin Potok and Gracanica. Goal of the research is to discover the preferences, motives, attitudes and interests of consumers for buying the organic products, based on a defined survey to recognise the basic features of supply and the demand of organic agricultural and food products. After analysing the conducted survey, we have discovered that the organic food market in Serbian enclaves in Kosovo has not been sufficiently developed; it is necessary to expand the range of organic agriculture products and a constant supply is required, better marketing, and better information and education of consumers in order to raise supply to a higher level.

Despite the usefulness of quantitative research, qualitative research methodologies are equally needed to allow researchers to better understand the important social and environmental factors affecting food choice and eating habits. The present paper contributes insights from narrative inquiry, a well-established qualitative methodology, to a food-related doctoral research study. The connections between food shoppers and the producer, family, friends and others in the food system, between eaters and the earth, and how these connections affect people's meaning-making of food and pathways to food citizenship, were explored in the research. The research used narrative inquiry methodology and focus groups for data collection. Five different food-ways in the Canberra region of Australia were selected for the present research; that is, community gardens, community-supported agriculture, farmers' markets, fresh food markets and supermarkets. Fifty-two people voluntarily attended eight focus groups with four to nine participants in each. From a practical perspective, the present paper offers a guide to the way in which narrative inquiry has been applied to one research project. The paper describes the application of narrative inquiry methodology, revealing the important place of narratives in generating new knowledge. The paper further outlines how phased narrative analysis can lead to a defensible and rigorous interpretive framework grounded in the data generated from people's stories and meaning-making. We argue that individual, social and system change will not be possible without further rigorous qualitative studies to inform and complement the empirical basis of public health nutrition practice.

China and America both have 7.5 MeV high energy X-ray accelerator. The radiological safety of food irradiated with 7.5 MeV X-rays (bremsstrahlung) has been investigated. Samples of meat and meat ash were located in a large volume of fresh meat at the position of the highest photoneutron fluence and irradiated to an X-ray dose of 15 kGy, twice the maximum dose allowed by the US FDA for meat irradiation. An evaluation of the corresponding radiation exposure from ingestion of the irradiated product has been compared to natural background radiation. The paper concludes that the risk to individuals from intake of food irradiated with X-rays from 7.5 MeV electrons, even with a broad energy spectrum, would be trivial. The common target materials are Au, Ta and W. The U.S, requires only Au and Ta can be used as food irradiation target materials and China has not yet relevant provisions. The first 7.5 MeV accelerator for food irradiation in China is under built, and will do the explore research for the choice of target material. (authors)

Persons accessing food from nonprofit distribution sites face numerous challenges and typically have significant unmet health needs. However, given limited and intermittent healthcare system engagement, this vulnerable population is underrepresented in clinical research. We sought to better understand the health needs of a nonclinical population to inform future research and interventions. Focus groups were conducted in English (n = 4) and Spanish (n = 4) with clients of Crossroads Community Services (CCS), the largest distributor of North Texas Food Bank. Discussions probed participants' health status, healthcare utilization, understanding and utilization of mammography, and attitudes toward participation in research. Participants included 42 CCS clients, primarily Hispanic or African American women. Participants reported multiple comorbid conditions among household members, yet utilization of health services was often limited by cost. The majority expressed interest in participating in research to communicate their health concerns and obtain emotional support. CCS clients represent a high-need, under-reached population willing to engage in health-related research that affords them opportunity to connect with peers in group settings and obtain information to improve management of daily life challenges. The Community Assistance Research (CARe) Initiative, a community-academic collaboration, establishes a much-needed opportunity for ongoing clinical research and intervention among this underserved population. © 2015 Wiley Periodicals, Inc.
Food preferences of winter bird communities in different forest types.

Directory of Open Access Journals (Sweden)

Swen C Renner

Full Text Available Food availability for forest birds is a function of habitat type, forest management regime, and season. In winter, it is also impacted by variations in the weather. In the current study we assessed the food preferences of wild bird populations in two types of forest (spruce and beech during the months of November 2010 to April 2011 in the Schwäbische Alb Biodiversity Exploratory, south-western Germany. Our aim was to investigate whether local bird communities preferred fat-rich, carbohydrate-rich or wild fruits and to determine how forest structure, seasonality and local weather conditions affected food preferences. We found higher bird activity in beech forests for the eleven resident species. We observed a clear preference for fat-rich food for all birds in both forest types. Snow cover affected activity at food stations but did not affect food preferences. Periods of extreme low temperatures increased activity.
Supply regimes in fisheries

Nielsen, Max

2006-01-01

Supply in fisheries is traditionally known for its backward bending nature, owing to externalities in production. Such a supply regime, however, exist only for pure open access fisheries. Since most fisheries worldwide are neither pure open access, nor optimally managed, rather between the extremes......, the traditional understanding of supply regimes in fisheries needs modification. This paper identifies through a case study of the East Baltic cod fishery supply regimes in fisheries, taking alternative fisheries management schemes and mesh size limitations into account. An age-structured Beverton-Holt based bio......-economic supply model with mesh sizes is developed. It is found that in the presence of realistic management schemes, the supply curves are close to vertical in the relevant range. Also, the supply curve under open access with mesh size limitations is almost vertical in the relevant range, owing to constant...

2011-12-01

Full Text Available The aim of this research was to evaluate the in vitro antimicrobial activity of seven essential oils against four different bacterial and five fungal strains that are involved in food poisoning and/or food decay: Staphylococcus aureus, Bacillus cereus, Escherichia coli, Salmonella enteritidis, Fusarium graminearum, Fusarium culmorum, Aspergillus flavus, Aspergillus oryzae and Aspergillus brasiliensis, using two methods: agar disc diffusion method and disc volatilization method. The majority of the selected essential oils presented inhibitory activity against all the microorganisms tested but essential oils of oregano, thyme and clove proved to develop the best antibacterial and antifungal activity both in direct contact and volatilization method and could be used for further investigation in active packaging of food.
About the high flow regime of the rivers of Kosovo and Metohia

Directory of Open Access Journals (Sweden)

Živković Nenad

2009-01-01

Full Text Available The examples from Kosovo and Metohia attempted to point to some problems in the domain of hydrogeographic regionalization. The river water regime, especially the phase of high flows which marks this regime, has been the topic of almost all researches which treat water resources of drainage basins. However, the thing that has not been achieved till now is the unique solution by which the classification of rivers would be made according to this feature. On this example it has been shown that even some older methods, based on genetic analysis of hydrograms and of global type, as well as some recent ones, with lot of quantitative entry and regional approaches, cannot with certainty answer all the challenges which river regimes bring with themselves. This work shows that apart from climate, orographic and physiognomic features of drainage basins, the periods of data processing and the analysis of individual intra-annual series of discharges are very important as well. Discretization on time periods shorter than one month, as well as elimination of the extreme values of discharges in the longtime series is recommended for the future research.
Exploration of extremely low q_e_d_g_e regime in KSTAR

The q_e_d_g_e < 2 regime had long been regarded as an experimentally forbidden regime due to magneto-hydrodynamic instabilities. However, RFX-MOD experiment demonstrated that the control of error field could enable the entrance and sustainment of the discharge even in the forbidden regime. We explored q_e_d_g_e < 2 regime in Korea superconducting tokamak advanced research (KSTAR) without any feedback or feedforward control of error field since the intrinsic level of error field in KSTAR is inherently comparable to the controlled level of other device. The discharge sustained at q_9_5 ∼ 1.9 for 800 ms that is at least one order of magnitude longer than the resistive wall time of the device. Furthermore, simulated error field applied by field error correction coils prevented the passage of q_e_d_g_e = 3 integer rational surface before reaching q_e_d_g_e = 2. The detailed analysis is on-going for revealing the role of error field in the excitation of limiting instability. (author)
Research document no. 20. The constitutionalizing of the international legal regime of the petroleum investments and the world market reconstruction

International Nuclear Information System (INIS)

Noel, P.

2000-09-01

We analyse the new international legal regime for upstream petroleum investments and ''state contracts'' in general. In striking contrast to the ''New international economic order'' and ''Permanent sovereignty over natural resources'' ideologies of the 1960 and 1970, the emerging regime promotes the sanctification of contractual economic rights; the strict definition of State sovereign prerogatives, and the severe limitation of their conditions of exercise; the internationalization of the settlement of disputes through direct firm-State arbitration; the integration of national territories in a competitive, transparent, non-discriminative global market for investment. We demonstrate that it is rooted in the principles of liberal constitutionalism, hence promoting the internationalization of the Rule of Law. Such a legal regime is conducive to the expansion of the market for petroleum rights, as it restores the institutional conditions for credible commitment by the State. It will also accelerate the trend toward the ''commoditization'' of hydrocarbon resources. Bilateral investments treaties (especially the United States BIT program) as well as multilateral/regional instruments both general (draft MAI, MIGA, MERCOSUR, ALENA) and energy-specific (Energy Charter Treaty) are analysed as the main pillars and diffusion mechanisms of the new regime. A final paragraph indicates the way forward: the evaluation of the impact of this new legal regime on the world oil supply curve, especially as it eventually reaches - or not - some of the lowest-cost, biggest-resources countries.

Harmful effects of chemical contaminants in food are of major health concern in Europe today. Lack of integration between basic research, risk assessment, and education severely hampers the efforts to reach European excellence in this area. The research activities that are carried out are small in scale and are not well integrated into a coherent structure. To tackle the fragmentation problems and to achieve synergistic effects and full European research potential, the European Commission has initiated a Network of Excellence called CASCADE or ''Chemicals as contaminants in the food chain: a network of excellence for research, risk assessment, and education'' The contract is running for five years and is worth over 14 million with partners from eighteen research centres. The network has the potential and goal to be a world force in knowledge on health issues related to chemical contaminants in food. Focus is on chemical residues that act via and/or interfere with cell regulation at the level of nuclear receptors. The risk assessment integration parts of the network aim to increase the awareness among scientists and others of the need to bring multiple aspects of scientific information into use in risk assessment.
World-Ecology and Ireland: The Neoliberal Ecological Regime

2016-03-01

Full Text Available Since the collapse of the Celtic Tiger, the socio-economic particularity of neoliberal capitalism in its Irish manifestation has increasingly been critiqued, but little attention has been paid to neoliberalism as ecology within Ireland. This article conducts an exploratory survey of the characteristics of the Irish neoliberal ecological regime during and after the Celtic Tiger, identifying the opening of new commodity frontiers (such as fracking, water, agro-biotechnology, and biopharma constituted in the neoliberal drive to appropriate and financialize nature. I argue for the usefulness of applying not only the tools of world-systems analysis, but also Jason W. Moore’s world-ecological paradigm, to analysis of Ireland as a semi-periphery. What is crucial to a macro-ecological understanding of Ireland’s role in the neoliberal regime of the world-ecology is the inextricability of its financial role as a tax haven and secrecy jurisdiction zone from its environmental function as a semi-peripheral pollution and water haven. We can adapt Jason W. Moore’s slogan that “Wall Street…becomes a way of organizing all of nature, characterized by the financialization of any income-generating activity” (Moore 2011b: 39 to say that to say that the “IFSC is a way of organizing nature,” with pernicious consequences for water, energy, and food systems in Ireland. Financial service centers and pharmaceutical factories, plantations and cattle ranches, tax havens and pollution havens, empires and common markets are all forms of environment-making that constellate human relations and extra-human processes into new ecological regimes. More expansive, dialectical understandings of “ecology” as comprising the whole of socio-ecological relations within the capitalist world-ecology—from farming to pharma to financialization—are crucial to forming configurations of knowledge able not only to take account of Ireland’s role in the environmental

Threats of nuclear terrorism are increasing after 9/11 terrorist attack. Treats include nuclear explosive device (NED) made by terrorist groups, radiological damage caused by a sabotage aiming nuclear facilities, and radiological dispersion device (RDD), which is also called 'dirty bomb'. In 9/11, Al Qaeda planed to cause radiological consequences by the crash of a nuclear power plant and the captured airplane. The evidence of a dirty bomb experiment was found in Afganistan by the UK intelligence agency. Thus, the international communities including the IAEA work substantial efforts. The leaders of 47 nations attended the 2010 nuclear security summit hosted by President Obama, while the next global nuclear summit will be held in Seoul, 2012. Most states established and are maintaining state's nuclear security regime because of the increasing threat and the international obligations. However, each state's nuclear security regime is different and depends on the state's environment. The methodology for the assessment of state's nuclear security regime is necessary to design and implement an efficient nuclear security regime, and to figure out weak points. The IAEA's INPRO project suggests a checklist method for State's nuclear security regime. The IAEA is now researching more quantitative methods cooperatively with several countries including Korea. In this abstract, methodologies to evaluate state's nuclear security regime by risk assessment are addressed

Despite the poverty in the world, part of all food produced in the world is wasted. The contrast of high food production in the world with hunger, food insecurity and food waste points to the need for combined action and the use of technologies as a solution to combat and eradicate hunger and food waste. Food banks have sprung up worldwide receiving food surpluses and passing on to the needy. These have been encouraged by the ONU - United Nations Organization, however, the lack of quality assurance of these foods already in the food bank has restricted the desired shipment. In this sense, ionizing radiation applied in food brought many positive results, such as increased validity and control insect infestation. So, the aim of this study was to initiate a partnership between irradiation and the food bank through the development of a questionnaire to evaluate the knowledge and acceptance of individuals in the food bank in Brazil. In addition, this study aimed to standardize a basis questionnaire for future research assessment of irradiated foods and disseminate irradiated food. For the construction of the questionnaire as a measuring instrument, a comprehensive and rigorous literature review was made. The questionnaire as a measurement instrument was submitted to the research ethics committee and approved. As a result, the questionnaire has three parts, personal issues, assertive issues and questions of multiple choices and finally an informative question with video. The questionnaire was applied in Ceagesp food bank in the biggest center of food in Brazil. (author)

Dams and water management for hydropower production, agriculture and other human activities alter the natural flow regime of rivers. The new river hydrograph components depend on the type of impoundment and the policy of regulation but such a different flow regime will likely affect the riparian environment. The main challenge in order to define sustainable flow releases is to quantify hydrological effects in terms of geomorphology and ecosystem response. A considerable lack of knowledge still affects the link hydrology-ecology and inadequate flow rules (e.g., minimal or residual flows) are consequently still widespread: further research in this direction is urgently required. We present an experiment, which aims to investigate the effects of different water stage regimes on riparian vegetation (salix Viminalis cuttings) development in a temperate region (Switzerland). This work describes the installation setup, together with the first results concerning the first of the two scheduled seasons of campaign. Sixty Salix cuttings were planted in non-cohesive sandy-gravel sediment within 1 meter tall plastic pots installed outside in the EPFL campus. After grouping them in three batteries, the water level within them has been varying following three river regimes simulated by adjusting the water level within the pots by means of an automatic hydraulic system. The three water level regimes reproduce a natural flow regime, a minimum residual flow policy, which only conserves peaks during flooding conditions, and an artificial regime conserving only low frequencies (e.g., seasonality) of the natural dynamic. The natural flow regime of the first battery has been applied for two months to the entire system; the three regimes above said started in June 2012. This triggered a plant response transitory regime, which we monitored by measuring plant growth, soil and atmospheric variables. Particularly, measures concern with branches development leaves photosynthesis and

We studied the variations of power and reactivity of a reactor when we raise in a continuous way the starting plates. During the subcritical regime (negative reactivity), the power is determined by reactivity and by the intensity of the sources of photo neutrons, produced during the previous work of the reactor. When, during the rise of the plates, the reactor, pass by the critical regime (zero reactivity), one notes that the reached power is independent of the initial reactivity. During the sur-critical regime (positive reactivity), the elevation of temperature of the uranium bars slows down the growth of reactivity due to the movements of the plates. The power stretches then toward a value that depends only on the regime of cooling of the reactor and the excess of the available reactivity. This survey permits to choose such a rise speed, that reactivity remains constantly lower to a value beyond which the piloting of the reactor becomes difficult. This result is not more valid, if the intensity of the sources is insufficient, what takes place during the first divergences and after a stop of long length.

A worldwide standard on food irradiation was adopted in 1983 by codex Alimentarius Commission of the Joint Food Standard Programme of the Food and Agriculture Organization (FAO) of the United Nations and The World Health Organization (WHO). As a result, 41 countries have approved the use of irradiation for treating one or more food items and the number is increasing. Generally, irradiation is used to: food loses, food spoilage, disinfestation, safety and hygiene. The number of countries which use irradiation for processing food for commercial purposes has been increasing steadily from 19 in 1987 to 33 today. In the frames of the national programme on the application of irradiation for food preservation and hygienization an experimental plant for electron beam processing has been established in Inst. of Nuclear Chemistry and Technology. The plant is equipped with a small research accelerator Pilot (19 MeV, 1 kW) and industrial unit Electronika (10 MeV, 10 kW). On the basis of the research there were performed at different scientific institutions in Poland, health authorities have issued permissions for irradiation for; spices, garlic, onions, mushrooms, potatoes, dry mushrooms and vegetables.

Slow food, fast food and the control of food intake.

de Graaf, Cees; Kok, Frans J

2010-05-01

This Perspective focuses on two elements of our food supply and eating environment that facilitate high energy intake: a high eating rate and distraction of attention from eating. These two elements are believed to undermine our body's capacity to regulate its energy intake at healthy levels because they impair the congruent association between sensory signals and metabolic consequences. The findings of a number of studies show that foods that can be eaten quickly lead to high food intake and low satiating effects-the reason being that these foods only provide brief periods of sensory exposure, which give the human body insufficient cues for satiation. Future research should focus on the underlying physiological, neurological and molecular mechanisms through which our current eating environment affects our control of food intake.

Aim of this research is the structural analysis by comparison of the biodegradable properties of two polymeric products made by non-biodegradable polymeric material (polypropylene TIPPLEN H949 A) and biodegradable polymeric material (ECOVIO IS 1335), under microorganism activity in order to give the best solution for the manufacture of food packaging biodegradable products. It presents the results of experimental determinations on comparative analysis of tensile strength for the two types of polymers. The sample weight variations after fungal biodegradation activity revealed that, after 3 months, there are no significant changes in polymeric substratum for non-biodegradable polymeric. The microscopically analysis showed that the fungal filaments did not strongly adhered on the non-biodegradable polymeric material, instead, both filamentous fungi strains adhered and covered the surface of the biodegradable sample with germinated filamentous conidia. The spectral analysis of polymer composition revealed that non-biodegradable polymer polypropylene spectra are identical for control and for samples that were exposed to fungal activity, suggesting that this type of sample was not degraded by the fungi strains. Instead, for biodegradable polymer sample, it was observed significant structural changes across multiple absorption bands, suggesting enzyme activity manifested mainly by Aspergillus niger strain. Structural analysis of interdisciplinary research results, lead, to achieving optimal injection molded technology emphasizing technological parameters, in order to obtain food packaging biodegradable products.

A principal aim of ecologists is to identify critical levels of environmental change beyond which ecosystems undergo radical shifts in their functioning. Both food-web theory and alternative stable states theory provide fundamental clues to mechanisms conferring stability to natural systems. Yet, it is unclear how the concept of food-web stability is associated with the resilience of ecosystems susceptible to regime change. Here, we use a combination of food web and ecosystem modelling to show that impending catastrophic shifts in shallow lakes are preceded by a destabilizing reorganization of interaction strengths in the aquatic food web. Analysis of the intricate web of trophic interactions reveals that only few key interactions, involving zooplankton, diatoms and detritus, dictate the deterioration of food-web stability. Our study exposes a tight link between food-web dynamics and the dynamics of the whole ecosystem, implying that trophic organization may serve as an empirical indicator of ecosystem resilience.

Research potential of food and nutrition in the Family Health Strategy: A structured review

Directory of Open Access Journals (Sweden)

Ivana Aragão Lira Vasconcelos

2014-01-01

Full Text Available OBJECTIVE: Determine the profile of research groups and publications with food and nutrition-related actions promoted by the Family Health Strategy in Brazil since 1994. METHODS: Two procedures were used: structured review and research group search. The former searched the databases Web of Science, Medline, Lilacs, SciELO and Embase, and followed the principles that guide systematic reviews in the Cochrane Collaboration. The references of the selected articles were also consulted. The research groups were searched in the Research Group Directory of the National Council for Scientific and Technological Development. RESULTS: A total of 54 articles published between 2002 and 2012 in 20 different journals were identified. Ten of these were retrieved from the references section of other articles. Focusing mostly on children from the Southeast region, these studies were coordinated by dieticians, nurses, and physicians. Diabetes Mellitus, high blood pressure, and breastfeeding were the most common topics (n=23. The quantitative methodology was employed by 42 articles, most about diagnoses. Only five research groups studied the Family Health Strategy, despite the growing number of studies in the area over the years. CONCLUSION: Despite the growing scientific production, the findings of this structured review indicate that few studies focused on food and nutrition in the Family Health Strategy, probably because of the existence of few research groups in the country. More comprehensive and consistent studies on the topic are needed.
Fire Regime Characteristics along Environmental Gradients in Spain

Directory of Open Access Journals (Sweden)

María Vanesa Moreno

2016-11-01

Full Text Available Concern regarding global change has increased the need to understand the relationship between fire regime characteristics and the environment. Pyrogeographical theory suggests that fire regimes are constrained by climate, vegetation and fire ignition processes, but it is not obvious how fire regime characteristics are related to those factors. We used a three-matrix approach with a multivariate statistical methodology that combined an ordination method and fourth-corner analysis for hypothesis testing to investigate the relationship between fire regime characteristics and environmental gradients across Spain. Our results suggest that fire regime characteristics (i.e., density and seasonality of fire activity are constrained primarily by direct gradients based on climate, population, and resource gradients based on forest potential productivity. Our results can be used to establish a predictive model for how fire regimes emerge in order to support fire management, particularly as global environmental changes impact fire regime characteristics.

[Review of food policy approaches: from food security to food sovereignty (2000-2013)].

Science.gov (United States)

López-Giraldo, Luis Alirio; Franco-Giraldo, Álvaro

2015-07-01

Food policies have attracted special interest due to the global food crisis in 2008 and promotion of the Millennium Development Goals, leading to approaches by different fields. This thematic review aims to describe the main theoretical and methodological approaches to food security and food sovereignty policies. A search was performed in databases of scientific journals from 2000 to 2013. 320 complete articles were selected from a total of 2,699. After reading the articles to apply the inclusion criteria, 55 items were maintained for analysis. In conclusion, with the predominance of food security as a guiding policy, food sovereignty has emerged as a critical response to be included in designing and researching food policies. Food policies are essential for achieving public health goals. Public health should thus take a leading role in linking and orienting such policies.
Sustaining a verification regime in a nuclear weapon-free world. VERTIC research report no. 4

International Nuclear Information System (INIS)

Moyland, S. van

1999-01-01

Sustaining high levels of commitment to and enthusiasm for the verification regime in a nuclear weapon-free world (NWFW) would be a considerable challenge, but the price of failure would be high. No verification system for a complete ban on a whole of weapon of mass destruction (WMD) has been in existence long enough to provide a precedent or the requisite experience. Nevertheless, lessons from the International Atomic Energy Agency's (IAEA) nuclear safeguards system are instructive. A potential problem over the long haul is the gradual erosion of the deterrent effect of verification that may result from the continual overlooking of minor instances of non-compliance. Flaws in the verification system must be identified and dealt with early lest they also corrode the system. To achieve this the verification organisation's inspectors and analytical staff will need sustained support, encouragement, resources and training. In drawing attention to weaknesses, they must be supported by management and at the political level. The leaking of sensitive information, either industrial or military, by staff of the verification regime is a potential problem. 'Managed access' techniques should be constantly examined and improved. The verification organisation and states parties will need to sustain close co-operation with the nuclear and related industries. Frequent review mechanisms must be established. States must invest time and effort to make them effective. Another potential problem is the withering of resources for sustained verification. Verification organisations tend to be pressured by states to cut or last least cap costs, even if the verification workload increases. The verification system must be effective as knowledge and experience allows. The organisation will need continuously to update its scientific methods and technology. This requires in-house resources plus external research and development (R and D). Universities, laboratories and industry need incentives to
Iterative functionalism and climate management regimes: From intergovernmental panel on climate change to intergovernmental negotiating committee

International Nuclear Information System (INIS)

Feldman, D.L.; Tennessee Univ., Knoxville, TN

1992-01-01

This paper contends that an iterative ''functionalist'' regime -- comprised of international organizations that monitor the global climate and perform scientific and policy research on prevention, mitigation, and adaptation strategies for response to possible global warming -- has developed over the past decade. A common global effort by scientists, diplomats, and others to negotiate a framework convention that would reduce emissions of carbon dioxide and other ''greenhouse gases'' has been brought about by this regime. Individuals that participate in this regime are engaged in several cooperative activities including: (1) international research on the causes and consequences of global change; (2) global environmental monitoring and standard-setting for analyses of climate data; and (3) negotiating a framework convention that places limits on greenhouse gas emissions by countries. The implications of this iterative approach for successful implementation of a treaty to forestall global climate change are discussed

This dissertation examines the transformations of “Taiwanese cuisine” under three different political regimes. In the Japanese colonial era, “Taiwanese cuisine” emerged as food for the elite and as the “food of the colony.” However, the arrival of the Nationalist government and migrants from mainland China transplanted a condensed Chinese culinary map to Taiwan, while Taiwanese cuisine became a regional cuisine which was placed at a much lower level in the culinary hierarchy. After the establ...
Combining food type(s) and food quantity choice in a new food choice paradigm based on vice-virtue bundles.

Science.gov (United States)

Haws, Kelly L; Liu, Peggy J

2016-08-01

Given the prevalence and rising rates of obesity in many countries, including the United States, much food decision-making research ultimately aims at understanding how consumers can make healthier choices. The two predominant choice paradigms used in food decision-making research ask consumers to choose (a) between a "vice" (or unhealthy food) and a "virtue" (or healthy food) or (b) among varying portion sizes of "vice." We propose a new food choice paradigm that encourages consumers to jointly consider both food type(s) choice and food portion size at each decision point. The purpose of this paradigm is two-fold. First, it aims to allow examination of more comprehensive eating behavior (e.g., to examine the overall composition of a plate of food rather than choice of a single food). Second, it aims to shift consumers towards including large proportions of virtues and smaller proportions of vice in their overall consumption portfolios. For this paradigm, we draw upon a recently introduced food product innovation called "vice-virtue bundles" (Liu et al., 2015) that illustrates the basis of this new food choice paradigm, in which food type(s) and portion decisions are made simultaneously. Accordingly, we first discuss relevant findings on vice-virtue bundles as well as the differences between simultaneous and sequential choice of multiple products. Second, we examine the benefits for managing and controlling one's consumption that are provided by vice-virtue bundles and this joint food choice paradigm more generally. Third and finally, we point out opportunities for future research by discussing (a) multiple factors that influence food choices, (b) decision processes affected by food choice paradigms, and (c) issues of generalizability related to the presence of vice-virtue bundles.

Health foods and foods with health claims in Japan

International Nuclear Information System (INIS)

Ohama, Hirobumi; Ikeda, Hideko; Moriyama, Hiroyoshi

2006-01-01

The terms 'nutraceuticals' and 'dietary or food supplements' are not very popular in Japan as compared to most of other countries. However, the concept of 'functional foods', which benefits the structure and function of the human body, is known as a result of research studies initiated on the health benefits of foods in 1984. The Ministry of Education organized a national research and development project to evaluate the functionalities of various foods. Researchers from diverse scientific fields succeeded to define new functions of food, successfully incorporating the previously recognized functions of nutrition, sensory/satisfaction and physiological effects of ingredients in foods. Some of the food manufacturers and distributors unfortunately capitalized on such food functionalities to promote 'health foods' by claiming drug-like effects and violating laws. In 1991, the Ministry of Health and Welfare (MHW) now as the Ministry of Health, Labor and Welfare (MHLW) introduced a 'foods for specified health uses' (FOSHU) system, for the control of such exaggerated and misleading claims. The other reason for such enforcement is due to an increase in the population of elderly people and lifestyle-related diseases that include obesity, diabetes mellitus, high blood pressure, cerebro- and cardiovascular diseases and cancer. In 2001, a new regulatory system, 'foods with health claims' (FHC) with a 'foods with nutrient function claims' (FNFC) system and newly established FOSHU was introduced. In addition, MHLW has changed the existing FOSHU, FNFC and other systems in 2005. Such changes include the new subsystems of FOSHU such as (1) standardized FOSHU (2) qualified FOSHU and (3) disease risk reduction claims for FOSHU. In the present chapter, two guidelines that require good manufacturing practice (GMP) and self-investigative systems for ensuring the safety of raw materials used for products in the dosage forms such as capsules, tablets, etc. have been discussed.

Spatial adjustments of mountain channels to changes in the sediment supply regime

Science.gov (United States)

Elgueta, M. A.; Hassan, M. A.; von Flotow, C. M.

2012-12-01

Sediment supply is a key controlling factor in bed morphology and sediment mobility. Under a low supply regime, bed structuring develops and reduces sediment mobility. Under high supply, structuring is suppressed and the bed exhibits patchiness. This study examines the spatial response of a mountain stream channel to changes in the sediment supply regime. To achieve this goal, a flume experiment was conducted in the Mountain Channel Hydraulic Experimental Laboratory at the University of British Columbia. An 18 meter long, one meter wide flume, with a slope of three percent was used. Seven continuous runs were conducted. Each of them lasted 40 hours, under constant flow and different sediment supply regimes, which included no feed, constant feed and episodic supply. In each run, bed elevation, bed grain size distribution, flow resistance, sediment mobility and degree of armoring were determined. Flume results were compared to field data from a 600 meter channel reach that exhibits rapid, riffle-pool and step-pool morphology in UBC Malcolm Knapp Research Forest. The study gave the possibility to analyze in detail the spatial adjustment of a mountain channel to changes in the sediment supply regime, including episodic inputs.
Regime dependence of photo-darkening-induced modal degradation in high power fiber amplifier (Conference Presentation)

Science.gov (United States)

Boullet, Johan; Vincont, Cyril; Jolly, Alain; Pierre, Christophe

2017-03-01

Thermally induced transverse modal instabilities (TMI) have attracted these five years an intense research efforts of the entire fiber laser development community, as it represents the current most limiting effect of further power scaling of high power fiber laser. Anyway, since 2014, a few publications point out a new limiting thermal effect: fiber modal degradation (FMD). It is characterized by a power rollover and simultaneous increase of the cladding light at an average power far from the TMI threshold together with a degraded beam which does not exhibit temporal fluctuations, which is one of the main characteristic of TMI. We report here on the first systemic experimental study of FMD in a high power photonic crystal fiber. We put a particular emphasis on the dependence of its average power threshold on the regime of operation. We experimentally demonstrate that this dependence is intrinsically linked to regime-dependent PD-saturated losses, which are nearly three times higher in CW regime than in short pulse picosecond regime. We make the hypothesis that the existence of these different PD equilibrium states between CW regime and picosecond QCW pulsed regime is due to a partial photo-bleaching of color centers in picosecond regime thanks to a higher probability of multi-photon process induced photobleaching (PB) at high peak power. This hypothesis is corroborated by the demonstration of the reversibility of the FMD induced in CW regime by simply switching the seed CW 1064 nm light by a short pulse, picosecond oscillator.
Study of neoclassical transport in the 1/ν regime for a research fusion reactor

International Nuclear Information System (INIS)

Kalyuzhnyj, V.N.; Kasilov, S.V.; Nemov, V.V.

2005-01-01

In frame of the concept of a steady-state operated research fusion reactor (RFR) in papers [1-4] the RFR with an increased plasma-wall detachment was proposed with the purpose to enable not only the production but also a long-term confinement of a self-sustained plasma at the existing technology level. In connection with complication of the corresponding magnetic configuration an investigation of the neoclassical transport is desirable for such systems. In the present work neoclassical transport for a magnetic configuration of l=2 torsatron type variant of RFR system with an additional opposite toroidal magnetic field is investigated numerically. A so-called 1/ν transport regime, in which the transport coefficients are increased with reduction of particle collision frequency ν is considered. For calculating of transport coefficients a technique, based on integration along magnetic field lines in a given stellarator magnetic field is used. The magnetic field of helical windings is calculated by Biot-Savart law. The obtained transport coefficients are presented in a standard form containing a factor depending on the magnetic field geometry. From analysis of the received results follows that in respect of the neoclassical transport the proposed magnetic configuration turns out to be closer to configuration of the classical stellarator (with helical winding), than to configuration of the classical torsatron/geliotron.

The ability to recognize the transition from the L-mode to the H-mode or from the H-mode to the improved H-mode reliably from a conveniently small number of measurements in real time is of increasing importance for machine control. Discriminant analysis has been applied to regime identification of plasma discharges in the ASDEX Upgrade tokamak. An observation consists of a set of plasma parameters averaged over a time slice in a discharge. The data set consists of all observations over different discharges and time slices. Discriminant analysis yields coefficients allowing the classification of a new observation. The results of a frequentist and a formal Bayesian approach to discriminant analysis are compared. With five plasma variables, a failure rate of 1.3% for predicting the L-mode and the H-mode confinement regime was achieved. With five plasma variables, a failure rate of 5.3% for predicting the H-mode and the improved H-mode confinement regime was achieved. The coefficients derived by discriminant analysis have been applied subsequently to discharges to illustrate the operation of regime identification in a real time control system

Addressing childhood obesity in Latin America requires a package of multisectoral, evidence-based policies that enable environments conducive to healthy lifestyles. Identify and examine key elements to translating research into effective obesity policies in Latin America. We examined obesity prevention policies through case studies developed with an expert in the specific policy. Policies were selected based on their level of implementation, visibility and potential impact to reduce childhood obesity. They include: (i) excise taxes on sugar sweetened beverages and energy-dense foods; (ii) front-of-package food label legislation; (iii) trans fatty acids removal from processed foods; and (iv) Ciclovías recreativas or 'open streets'. Case studies were coded to identify components that explained successful implementation and sustainability using the Complex Adaptive Health Systems framework. The analysis identified key elements for effective and sustainable policy, including evidence justifying policy; evidence-based advocacy by civil society; political will; and legislation and skillful negotiations across government, academia, the private sector and civil society. Scientific evidence and evaluation played an important role in achieving tipping points for policies' launch and sustain effective implementation. Well-coordinated, intersectoral partnerships are needed to successfully implement evidence-based anti-obesity policies. Prospective policy research may be useful for advancing knowledge translation. © 2017 The Authors. Obesity Reviews published by John Wiley & Sons Ltd on behalf of World Obesity.

Abdul Manaf, Nor Aziah; Mas'ud, Abdulsalam; Ishak, Zuaini; Saad, Natrah; Russell, Alex

2016-01-01

This paper identifies a gap in the current literature relating to the attractiveness of petroleum fiscal regimes and suggests that establishing a measurement scale based on relevant factors drawn from the extant literature and on the perceptions of experts would complement the economic models currently in use and could become an industry standard. It will undoubtedly influence the petroleum fiscal policies and practices of petroleum producing countries. The methodology used involved a review of literature to identify factors that enhance the attractiveness of petroleum fiscal regimes; deploying experts to validate the appropriateness of the identified factors; conducting exploratory factor analysis and evaluating the internal consistency reliability of the construct's dimensions; performing confirmatory analysis for convergence and discriminant validity of the dimensions; and computing model fit indices to evaluate the goodness of fit of the four-factor correlated attractiveness petroleum fiscal regime scale. The results obtained suggest that a credible and manageable scale for assessing the attractiveness of petroleum fiscal regimes can be readily constructed. This research has taken the first important pioneering step in the construction of a globally applicable scale, the mechanics of which will require extension of our research, and consequently makes a significant contribution to policymaking and literature. - Highlights: • Existing literature lacks a broad scale for assessing the attractiveness of petroleum fiscal regimes. • A scale incorporating 14 items was constructed and evaluated by experts in Malaysia. • It was then validated through exploratory and confirmatory analyses as well as model-fit indices. • A credible and comprehensive scale is now established for use by policymakers and researchers.

Emphasizing features of the manifestation of currency exchange rate in Ukrainian practice is a precondition for choosing the optimal exchange rate regime for Ukraine, which, in its turn, will provide an opportunity to reduce inflation and implement effective tools of monetary and fiscal policies to promote further economic growth and competitiveness of the country. The uses of free-floating exchange rate and «currency board» regimes have either positive effects for Ukraine or certain threats. Methodology. This research is based on a synthesis of data on the uses of exchange rate regimes in Ukraine as an independent. It is considered angular regimes, which are by far the most suitable for Ukraine in terms of the European vector of its development. Peculiarities of using these regimes are revealed and their major threats to the domestic economy are pointed out. This article analyzes the dynamics of the trade balance of payments of Ukraine, the dynamics of the commodity structure of Ukraine`s exports and imports and the external debt of Ukraine. Results. Taking into account the experience of countries, which were in crisis situations, they show the necessity of the uses of freefloating exchange rate regime and possibilities of «currency board» regime, despite threats that they may have. World experience testifies the implementation of structural reforms, effective monetary policy, fiscal policy and discipline of the government. Thorough preparation of Ukraine’s transition to the «currency board» regime can justify itself in conditions of crisis and provide impetus to Ukrainian economy benefits. The paper defines conditions under which the success of a new model of exchange rate policy will be achieved. Practical implications. The study accents attention on the specifics of the uses of the

Energy transition or incremental change? Green policy agendas and the adaptability of the urban energy regime in Los Angeles

International Nuclear Information System (INIS)

Monstadt, Jochen; Wolff, Annika

2015-01-01

Drawing on recent research in urban policy studies and social studies of technology, this paper examines the capability of urban energy regimes in adapting to environmental policy pressures. Focusing on the case of the City of Los Angeles, we critically analyze the transformative capacity of the city's recent energy and climate policies and the innovation patterns of its urban infrastructure regime. This case study suggests that despite considerable success in switching from coal to renewable energies, the patterns of sociotechnical change in Los Angeles still tend to supplement and sustain the existing regime. Sociotechnical change in Los Angeles tends to unfold incrementally through adjustments within the established patterns of the existing regime. - Highlights: • Theory-guided case study on the transition of the urban energy regime in Los Angeles. • Evaluation of the transformative capacity of environmental policies. • Assessment of the adaptability and innovation patterns of urban infrastructure regimes. • The policy changes have sustained the existing regime and unfold incrementally

The basic research on food irradiation in Japan was begun around 1955 by universities and national laboratories. In 1967, food irradiation was designated to the specific general research on atomic energy, and the national project on large scale was continued until 1983. As the result, the treatment of germination prevention for potatoes was approved by the Ministry of Health and Welfare in 1972. The Co-60 gamma ray irradiation facility of Shihoro Agricultural Cooperative is famous as the facility that succeeded in the practical use of food irradiation for the first time in the world. But the practical use of food irradiation stagnates and the research activities were reduced in Japan due to the circumstances thereafter. The effect of radiation to foods and living things is explained. The features of the radiation treatment of foods are small temperature rise, large transmissivity, no residue, the small loss of nutrition and large quantity, continuous treatment. The safety of irradiated foods is explained. The subjects for hereafter are discussed. (K.I.)

Food insecurity is a public health concern. Food security includes the pillars of food access, availability and utilisation. For some indigenous peoples, this may also include traditional foods. To conduct a scoping review on traditional foods and food security in Alaska. Google Scholar and the High North Research Documents were used to search for relevant primary research using the following terms: "traditional foods", "food security", "access", "availability", "utilisation", "Alaska", "Alaska Native" and "indigenous". Twenty four articles from Google Scholar and four articles from the High North Research Documents were selected. The articles revealed three types of research approaches, those that quantified traditional food intake (n=18), those that quantified food security (n=2), and qualitative articles that addressed at least one pillar of food security (n=8). Limited primary research is available on food security in Alaskan. Few studies directly measure food security while most provide a review of food security factors. Research investigating dietary intake of traditional foods is more prevalent, though many differences exist among participant age groups and geographical areas. Future research should include direct measurements of traditional food intake and food security to provide a more complete picture of traditional food security in Alaska.

The quality of food for the astronaut accomplishing the mission in the space is one of the most important matters, and it is time to study and develop Korean space food for the Korean astronaut in the space. Therefore, in the beginning of the space exploration era, it is necessary to establish a national long-term plan and study and develop Korean space food in order to provide food with better quality for the astronaut accomplishing the space mission. Using current food processing, preservation, and packaging technology, it is necessary to develop the Korean space food, provide Korean astronaut studying at the international space station, and study the future space food systems used for the long-term space voyage and planet habitat base in the era of space exploration. Space food is analyzed through nutritional analysis, sensory evaluation, storage studies, packaging evaluations, and many other methods before its final shipment on the space shuttle. Each technology developed for the advanced food system must provide the required attribute to the food system, including safety, nutrition, and acceptability. It is anticipated that the duration of the exploration class missions can be at least 2, 3 years, and one of the biggest challenges for these missions will be to provide acceptable food with a shelf-life of 3-5 years. The development of space food process/preservation technology and its ripple effect will make a contribution to the improvement of nation's international phase, and the developed space food will potentially be used for combat ration and emergency/special food like the U. S. A. In the 21th century of space exploration era, the development of the advanced food system and life support system in the Mars space base as well as the space shuttle will strengthen the capability to precede the future space exploration era

This paper deals with the influence of flow regime (laminar, transition or turbulent) on the internal flow behavior, and how it affects the spray development in diesel nozzles. In particular, the research described here aims at studying and quantifying the internal flow regime effects on the spray behavior. With this purpose, internal flow results, based on mass flow rate and momentum flux measurements performed on three different tapered nozzles and which helped to determine the flow regime, has been taken into account as a point of departure for the spray behavior analysis. Thus, in this work, spray macroscopic visualization tests have been performed and analyzed which clearly revealed a change in the behavior of the angle and penetration of the spray related to the change of the flow nature. Moreover, with all the experimental data available, it has been possible to relate macroscopic parameters of the spray with those describing the internal flow (momentum and effective velocity) or the geometry of the nozzle (length or diameter) through correlations.

Full Text Available The solution of the problem of food security in the region plays an important role in providing the population with the necessary food. The article describes ways to achieve food security. Different opinions are presented on the causes of the problem of food security, in particular the spread of genetically modified organisms, as well as low incomes of the population, the volatility of food prices and insignificant reproduction opportunities. The analysis of production and consumption of various food products in the Russian Federation (RF in recent years has been carried out. Dynamics of consumption of the main types of food in the Voronezh region is also presented. An analysis has been made of the production and consumption of various food products in the Russian Federation (RF in recent years. Dynamics of consumption of the main types of food in the Voronezh region is also presented. A solution to the problem of food security with flour culinary products using non-traditional plant raw materials, also used as functional food products, was proposed. Examples are given of improving the quality of food products and increasing the content of dietary fiber and other useful nutrients, thanks to the use of secondary raw materials, bugs and processed products of plant origin. The food security of the region has only conditional territorial localization, since the economic relations that arise between the subjects of the food sector cover all subjects of the regional economy without exception. A special role in these relations in the conditions that have developed up to now is played by organizations related to the sphere of food production, as well as organizations that supply them with the most scarce and significant resources, i.e. organization of education, research and development. That is why, we believe that the main emphasis in the study of food security should be made on the specifics of the functioning of industrial organizations occupying a

Water temperatures fluctuate in time and space, creating diverse thermal regimes on river networks. Temporal variability in these thermal landscapes has important biological and ecological consequences because of nonlinearities in physiological reactions; spatial diversity in thermal landscapes provides aquatic organisms with options to maximize growth and survival. However, human activities and climate change threaten to alter the dynamics of riverine thermal regimes. New data and tools can identify particular facets of the thermal landscape that describe ecological and management concerns and that are linked to human actions. The emerging complexity of thermal landscapes demands innovations in communication, opens the door to exciting research opportunities on the human impacts to and biological consequences of thermal variability, suggests improvements in monitoring programs to better capture empirical patterns, provides a framework for suites of actions to restore and protect the natural processes that drive thermal complexity, and indicates opportunities for better managing thermal landscapes.

A total of 19 pesticide preparations were used according to agricultural practice in six trials in apple orchards. Using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), premature Golden Delicious apples collected 64, 50, 36 days before harvest and mature fruit were examined for residues of active ingredients. No residues of triflumuron, triazamate, chlorpyrifos, etofenprox, fenoxycarb, kresoxim-methyl, cyprodinyl, difenoconazole or thiram were detected in the first sampling. Also, the levels of chlorpyrifos-methyl, penconazole, tebuconazole and tolylfluanid dropped during the pre-harvest interval. Detectable residues of pyridaben, thiacloprid, trifloxystrobin and tetraconazole in harvested fruits were below 0.01 mg kg(-1), which is the maximum concentration of residues acceptable by baby-food producers in any raw material. The only residues exceeding this concentration were captan and teflubenzuron. Based on the data, farmers can choose pesticides for optimal treatment of plants, while enabling growth of a safe crop suitable for baby-food production.
Flow Regime Classification and Hydrological Characterization: A Case Study of Ethiopian Rivers

Full Text Available The spatiotemporal variability of a stream flow due to the complex interaction of catchment attributes and rainfall induce complexity in hydrology. Researchers have been trying to address this complexity with a number of approaches; river flow regime is one of them. The flow regime can be quantified by means of hydrological indices characterizing five components: magnitude, frequency, duration, timing, and rate of change of flow. Similarly, this study aimed to understand the flow variability of Ethiopian Rivers using the observed daily flow data from 208 gauging stations in the country. With this process, the Hierarchical Ward Clustering method was implemented to group the streams into three flow regimes (1 ephemeral, (2 intermittent, and (3 perennial. Principal component analysis (PCA is also applied as the second multivariate analysis tool to identify dominant hydrological indices that cause the variability in the streams. The mean flow per unit catchment area (QmAR and Base flow index (BFI show an incremental trend with ephemeral, intermittent and perennial streams. Whereas the number of mean zero flow days ratio (ZFI and coefficient of variation (CV show a decreasing trend with ephemeral to perennial flow regimes. Finally, the streams in the three flow regimes were characterized with the mean and standard deviation of the hydrological variables and the shape, slope, and scale of the flow duration curve. Results of this study are the basis for further understanding of the ecohydrological processes of the river basins in Ethiopia.

States and school districts around the country are developing policies that set nutrition standards for competitive foods and beverages sold outside of the US Department of Agriculture's reimbursable school lunch program. However, few tools exist for monitoring the implementation of these new policies. The objective of this research was to develop a computerized assessment tool, the Food and Beverage Environment Analysis and Monitoring System (FoodBEAMS), to collect data on the competitive school food environment and to test the inter-rater reliability of the tool among research and nonresearch professionals. FoodBEAMS was used to collect data in spring 2007 on the competitive foods and beverages sold in 21 California high schools. Adherence of the foods and beverages to California's competitive food and beverage nutrition policies for schools (Senate Bills 12 and 965) was determined using the data collected by both research and nonresearch professionals. The inter-rater reliability between the data collectors was assessed using the intraclass correlation coefficient. Researcher vs researcher and researcher vs nonresearcher inter-rater reliability was high for both foods and beverages, with intraclass correlation coefficients ranging from .972 to .987. Results of this study provide evidence that FoodBEAMS is a promising tool for assessing and monitoring adherence to nutrition standards for competitive foods sold on school campuses and can be used reliably by both research and nonresearch professionals.

The aim of this study was to improve cage systems for maintaining adult honey bee (Apis mellifera L.) workers under in vitro laboratory conditions. To achieve this goal, we experimentally evaluated the impact of different cages, developed by scientists of the international research network COLOSS (Prevention of honey bee COlony LOSSes), on the physiology and survival of honey bees. We identified three cages that promoted good survival of honey bees. The bees from cages that exhibited greater survival had relatively lower titers of deformed wing virus, suggesting that deformed wing virus is a significant marker reflecting stress level and health status of the host. We also determined that a leak- and drip-proof feeder was an integral part of a cage system and a feeder modified from a 20-ml plastic syringe displayed the best result in providing steady food supply to bees. Finally, we also demonstrated that the addition of protein to the bees' diet could significantly increase the level ofvitellogenin gene expression and improve bees' survival. This international collaborative study represents a critical step toward improvement of cage designs and feeding regimes for honey bee laboratory experiments.

Food irradiation is to contribute to the stable security of foodstuffs which is the fundamental condition of human survival by improving the preservation of foodstuffs and food sanitation utilizing the biological effect due to irradiation. The research and development have been carried out internationally since 1950s, but after the safety declaration of irradiated foods in 1980 by the international organ concerned, the permission and practical use for foods in various foreign countries, the technology transfer to developing countries and so on have been advanced. At present, food irradiation is permitted in 38 countries, and the practical irradiation is carried out in 24 countries. In Japan, the irradiation of potatoes to prevent germination was permitted in 1972, and the practical irradiation on potatoes of yearly 15,000 t is carried out. In the near future, irradiated foods will appear in international foodstuff market, and Japan which imports foodstuffs must cope with them. Foodstuffs and the safety, food irradiation, the soundness of irradiated foods, food irradiation in various foreign countries and Japan, the trend of international organs and the criticism of food irradiation are reported.

FEL in transverse optical klystron regime

International Nuclear Information System (INIS)

Scarlat, F.; Baltateanu, N.

1994-01-01

Among all operational regimes of free electron laser (FEL), the transverse optical regime (TOK) requires the least stringent electron beam parameters. The device associated to this regime, also defined as FEL with two or more components, consists of two or more identical interaction sections separated by one or more drift distances among themselves. Starting from the motion equations which describe the interaction between an electron and the radiation inside the undulator, one can obtain some practical expressions for the calculation of the efficiency of the energy transfer from the electron to the radiation, and the gain of the external coherent radiation for a FEL in TOK with three cavities.

The role of the media in establishing international security regimes

Directory of Open Access Journals (Sweden)

Chanan Naveh

2005-04-01

Full Text Available This article focuses primarily on the media's impact on international security regimes. It explores the ways in which the media affect the lifecycles of international regimes, from the time they are first conceived of, through their establishment, consolidation and stabilization, up until their ultimate demise. Although this paper highlights the media's role in the evolution of security regimes, it is clear that, regardless of the regime in question, media play a role throughout the lifecycle of all international regimes, whatever their character. In order to analyze the relationships of the media with security regimes in general, and specifically their contribution to each stage in their development, the article utilizes methodologies from the field of communication studies. It examines the media's agenda, "news values" and various functions, and their ability to mobilize public support for the particular issue of the regime. To date, most studies have explored the interaction between media communication patterns and global developments at the state level, or in relation to the formulation of foreign policy, while largely ignoring the international dimension of the relationship. This article attempts to remedy this situation, and the relevant processes are analysed in a case study of the anti-Iraq international security regime. It should be noted that although the paper focuses on the specific anti-Iraqi regime, it is part of a more general Anti-Rogue actors regime which includes the war against global terrorism. The study of the development of the anti-Iraq press-security regime teaches us that during international crises the media mobilize and unanimously support the regime fighting the "bad guys." But, when the regime develops and enters disputed turfs and begins to lose its legitimacy, media support diminishes, and the media may even develop into an opposing force and may join the actors fighting against this regime. Moreover, the study of

Regimes of mini black hole abandoned to accretion

Science.gov (United States)

Paik, Biplab

2018-01-01

Being inspired by the Eddington’s idea, along with other auxiliary arguments, it is unveiled that there exist regimes of a black hole that would prohibit accretion of ordinary energy. In explicit words, there exists a lower bound to black hole mass below which matter accretion process does not run for black holes. Not merely the baryonic matter, but, in regimes, also the massless photons could get prohibited from rushing into a black hole. However, unlike the baryon accretion abandoned black hole regime, the mass-regime of a black hole prohibiting accretion of radiation could vary along with its ambient temperature. For example, we discuss that earlier to 10‑8 s after the big-bang, as the cosmological temperature of the Universe grew above ˜ 1014 K, the mass range of black hole designating the radiation accretion abandoned regime, had to be in varying state being connected with the instantaneous age of the evolving Universe by an “one half” power law. It happens to be a fact that a black hole holding regimes prohibiting accretion of energy is gigantic by its size in comparison to the Planck length-scale. Hence the emergence of these regimes demands mini black holes for not being viable as profound suckers of energy. Consideration of accretion abandoned regimes could be crucial for constraining or judging the evolution of primordial black holes over the age of the Universe.

The functional food industry is expanding, yet research into consumer perceptions of functional foods is limited. Older adults could benefit from functional foods due to age-related food and health issues. This research gathered information about functional foods from community-dwelling older adults (n = 200) who completed a researcher-administered questionnaire about consumption, food matrices, bioactive ingredients, and health areas addressed through functional foods. Overall prevalence of functional food consumption was found to be 93.0%. Commonly consumed foods included yogurt with probiotics (56.0%), eggs with omega-3 fatty acids (37.0%), and bread with fiber (35.5%). Functional food matrices primarily consumed were yogurt (51.5%), bread (44.0%), and cereal (40.0%). The primary functional food bioactive consumed was dietary fiber (79.5%). Most participants (86.2%) indicated that they consume functional foods to improve health, and the major areas specified were osteoporosis/bone health (67.5%), heart disease (61.0%), and arthritis (55.0%). These results inform health professionals regarding the potential of functional foods to support health among older adults.

The contribution of this research is to propose a new problem of linear-mixed programming model (LMPM) for the allocation-packing of multiple pantries personalized for Food Banks (FB) considering the opinion of the Decision Maker (DM) in the selection of the best solution. Design/methodology/approach: A food allocation-packing system is modeled as a mixed integer problem (MIP) and a fuzzy mixed integer linear problem (FMILP). 250 families and 100 products were considered. The solutions were found using Lingo 13® (for both deterministic and fuzzy model). To select a good solution in the fuzzy model, this research adapted an interactive method proposed in the literature. The relevance of this modification is that the opinion of a decision maker (DM) is included and considered. Findings: The results for the deterministic and fuzzy model are compared in terms of their accomplishment of the restrictions (mainly nutritional and logistic) and the time needed to achieve a solution. Research limitations/implications: This paper was done considering quantity, weight and volume restrictions so that the pantry will contain a variety of products; it is not considered how the products will be stored into the pantry. Practical implications: This research proposes an alternative food management system at a food bank. The proposed system organizes the content of customized food pantries by the bias of a food allocation model. Social implications: Our paper analyzes a Food Bank (FB) in México. With this proposal, food will be distributed to families in poverty considering their particular nutritional needs. Originality/value: The main contribution of this article lies in the proposal of a new model of mixed integer linear problem (MILP) for the allocation-packing of food, solved with fuzzy possibilistic programming that simultaneously considers nutritional and logistic restrictions applied to a type of organization that has been little studied in the literature and where the

Food irradiation and the consumer

International Nuclear Information System (INIS)

Thomas, P.A.

1990-01-01

The poster presents a review of research work undertaken on the perception and understanding that consumers have of food irradiation. Food irradiation is not a revolutionary new food processing technique, in fact it is probably one of the most investigated methods presently available. Many countries such as Belgium, France, Denmark, Italy, Spain, the Netherlands and the United States of America permit food irradiation. In Britain it is presently banned although this is currently under review. Awareness of food irradiation by the general public in Britain, although not extensively researched would appear to be increasing, especially in the light of recent media coverage. New quantitative and qualitative work indicates that the general public are concerned about the safety and effectiveness of food irradiation. Research has shown that a large proportion of consumers in Britain, if given the opportunity to purchase irradiated food, would not do so. Further exploration into this response revealed the fact that consumers are confused over what food irradiation is. In addition, there is concern over the detection of irradiated food. The views presented in this paper, of the consumer reaction to irradiated food are of great importance to those involved in the food industry and industries allied to it, which are ultimately dependent on the consumer for their commercial survival.

Study of the impact of food irradiation on preventing losses: Experience in Africa. Proceedings of a final research co-ordination meeting

International Nuclear Information System (INIS)

2002-05-01

There have been positive developments on food irradiation in different regions of the world, especially in the United States of America and several Asian and Latin American countries. In some countries in Africa, this technology has been studied in the past few decades with encouraging results. To assist these countries in conducting pilot scale research and development on irradiation of specific commodities of interest to them including market testing and feasibility to establish commercial irradiators for multi-purpose application, a Coordinated Research Project (CRP) on Impact of Irradiation to Prevent Food Losses in Africa was carried out between 1995 and 1999. This CRP demonstrated that food irradiation has a potential to reduce losses of basic staple food crops including yams, dried and smoked fish, potatoes and onions through pilot scale experiments carried out in some African countries. Small scale market testing of such irradiated food such as spices, potatoes and onions showed encouraging results. In some countries (Cote d'Ivoire, Egypt, Ghana, Senegal and South Africa), it is feasible to establish commercial irradiation facilities for treating food. In Morocco, irradiation shows a potential to meet quarantine requirements in international food trade. It should be noted that commercial scale application of irradiation of some food products has been carried out in South Africa since the 1980s

Full Text Available Asia's inancial crisis in July 1997 affects currency, capital market, and real market throughout Asian countries. Countries in southeast region (ASEAN, including Indonesia, Malaysia, Philippines, Singapore, and Thailand, are some of the countries where the crisis hit the most. In these countries, where inancial sectors are far more developed than real sectors and the money market sectors, most of the economic activities are conducted in capital market. Movement in the capital market could be a proxy to describe the overall economic situation and therefore the prediction of it could be an early warning system of economic crises. This paper tries to investigate movement in ASEAN (Indonesia, Malaysia, Philippines, Singapore, and Thailand capital market to build an early warning system from inancial sectors perspective. This paper will be very beneicial for the government to anticipate the forthcoming crisis. The insight of this paper is from Hamilton (1990 model of regime switching process in which he divide the movement of currency into two regimes, describe the switching transition based on Markov process and creates different model for each regimes. Differ from Hamilton, our research focuses on index return instead of currency to model the regime switching. This research aimed to ind the probability of crisis in the future by combining the probability of switching and the probability distribution function of each regime. Probability of switching is estimated by categorizing the movement in index return into two regimes (negative return in regime 1 and positive return in regime 2 then measuring the proportion of switching to regime 1 in t given regime �

2005-01-01

The purpose of this project is to make a Thermal Hydraulic Analysis of Main Condensate System for getting real-time answer of installation during regimes occurring during normal and abnormal operation. To obtain the analyses the MMS code was used. The boundaries of the systems analysis are extended to Main Feedwater System in order to get a realistic response of Deaerator equipment which are situated between those two systems and have entrances from both systems. In this way we made a complex analysis with main condenser and steam generators as boundaries. We obtained a model for the entire chain of condensate and feedwater preheater with interface just turbine bleed steam. From that we could reduce the number of assumptions necessary to make the analysis. The analyses consist in hydraulics and thermal hydraulics analyses, respectively. For the first case analysed are: - the nominal operation regime with main condensate pumps; - start-up regime with total circulate of condensate to condenser; - 25% MCR (Maximum Continuous Rate) regime (this regime was used in designing the condensate regulating valves at low flow; - 40% MCR regime (with circulate of some condensate flow to condenser); - operating regime of 60% MCR with one main condensate pump operating; - operating regime with auxiliary condensate pump; - operating regime with discharging a condensate flow to condensate storage tank. The thermal hydraulic analyses deal with normal and abnormal operating regimes, respectively. In the first case analysed are the following regimes: - nominal operating regime with main condensate pump operating 100% MCR; - transient regime, 100-80% MCR; - transient regime, 100-80-60% MCR with two pumps in operation and 60 % MCR with one main condensate pump in operation; - transient regime, 100-80-60-60-40 % MCR; - shut-down regime; - start-up regime from Hot zero power to rated power regime. Finally, for the abnormal operating regimes the analyses concerned: - transient regime 100

Asymptotic preserving and all-regime Lagrange-Projection like numerical schemes: application to two-phase flows in low mach regime

International Nuclear Information System (INIS)

Girardin, Mathieu

2014-01-01

Two-phase flows in Pressurized Water Reactors belong to a wide range of Mach number flows. Computing accurate approximate solutions of those flows may be challenging from a numerical point of view as classical finite volume methods are too diffusive in the low Mach regime. In this thesis, we are interested in designing and studying some robust numerical schemes that are stable for large time steps and accurate even on coarse meshes for a wide range of flow regimes. An important feature is the strategy to construct those schemes. We use a mixed implicit-explicit strategy based on an operator splitting to solve fast and slow phenomena separately. Then, we introduce a modification of a Suliciu type relaxation scheme to improve the accuracy of the numerical scheme in some regime of interest. Two approaches have been used to assess the ability of our numerical schemes to deal with a wide range of flow regimes. The first approach, based on the asymptotic preserving property, has been used for the gas dynamics equations with stiff source terms. The second approach, based on the all-regime property, has been used for the gas dynamics equations and the homogeneous two-phase flows models HRM and HEM in the low Mach regime. We obtained some robustness and stability properties for our numerical schemes. In particular, some discrete entropy inequalities are shown. Numerical evidences, in 1D and in 2D on unstructured meshes, assess the gain in term of accuracy and CPU time of those asymptotic preserving and all-regime numerical schemes in comparison with classical finite volume methods.

Sodhi Vijay

2012-01-01

Full Text Available The most of past studies in foaming trickle bed reactors aimed at the improvement of efficiency and operational parameters leads to high economic advantages. Conventionally most of the industries rely on frequently used gas continuous flow (GCF where operational output is satisfactory but not yields efficiently as in pulsing flow (PF and foaming pulsing flow (FPF. Hydrodynamic characteristics like regime transitions are significantly influenced by foaming nature of liquid as well as gas and liquid flow rates. This study’s aim was to demonstrate experimentally the effects of liquid flow rate, gas flow rates and liquid surface tension on regime transition. These parameters were analyzed for the air-aqueous Sodium Lauryl Sulphate and air-water systems. More than 240 experiments were done to obtain the transition boundary for trickle flow (GCF to foaming pulsing flow (PF/FPF by use excessive foaming 15-60 ppm surfactant compositions. The trickle to pulse flow transition appeared at lower gas and liquid flow rates with decrease in liquid surface tension. All experimental data had been collected and drawn in the form of four different transitional plots which are compared and drawn by using flow coordinates proposed by different researchers. A prominent decrease in dynamic liquid saturation was observed especially during regime transitional change. The reactor two phase pressure evident a sharp rise to verify the regime transition shift from GCF to PF/FPF. Present study reveals, the regime transition boundary significantly influenced by any change in hydrodynamic as well as physiochemical properties including surface tension.

Using the 2002 World Health Survey, we examine the association between welfare state regimes, gender and mental health among 26 countries classified into seven distinct regimes: Conservative, Southeast Asian, Eastern European, Latin American, Liberal, Southern/Ex-dictatorship, and Social Democratic. A two-level hierarchical model found that the odds of experiencing a brief depressive episode in the last 12 months was significantly higher for Southern/Ex- dictatorship countries than for Southeast Asian (odds ratio (OR) = 0.12, 95% confidence interval (CI) 0.05-0.27) and Eastern European (OR = 0.36, 95% CI 0.22-0.58) regimes after controlling for gender, age, education, marital status, and economic development. In adjusted interaction models, compared to Southern/Ex-dictatorship males (reference category), the odds ratios of depression were significantly lower among Southeast Asian males (OR = 0.16, 95% CI 0.08-0.34) and females (OR = 0.23, 95% CI 0.10-0.53) and Eastern European males (OR = 0.41, 95% CI 0.26-0.63) and significantly higher among females in Liberal (OR = 2.00, 95% CI 1.14-3.49) and Southern (OR = 2.42, 95% CI 1.86-3.15) regimes. Our results highlight the importance of incorporating middle-income countries into comparative welfare regime research and testing for interactions between welfare regimes and gender on mental health.

Food pictures are suitable visual tools for quantize food and nutrient consumption avoiding bias due to self-assessments. To determine the perception of food portion size and to establish the efficacy of food pictures for dietaries assessments. A food frequency questionnaire (FFQ) including 118 food items of daily consumption was applied to 30 adults representative of Córdoba, Argentina, population. Among several food models (paper maché, plastics) and pictures, those which more accurately filled the purpose were selected. 3 small, median and large standard portion size were determined. Data were evaluated with descriptive statistics tools and Chi square adherence test. The assessment of 51 percent of the food was assayed in concordance with the reference size. In general, the remainder was overestimated. The 90 percent of volunteers concluded that the pictures were the best visual resource. The photographic atlas of food is an useful material for quantize the dietary consumption, suitable for many types of dietaries assessments. In conclusion, comparison among pictures of three portions previously standardized for each food is highly recommendable.

Kelly, Bridget; Bochynska, Katarzyna; Kornman, Kelly; Chapman, Kathy

2008-11-01

The aim of the present study was to describe the nature and extent of food marketing on popular children's websites and food product websites in Australia. Food product websites (n 119) and popular children's websites (n 196) were selected based on website traffic data and previous research on frequently marketed food brands. Coding instruments were developed to capture food marketing techniques. All references to food on popular children's websites were also classified as either branded or non-branded and according to food categories. Websites contained a range of marketing features. On food product websites these marketing features included branded education (79.0% of websites), competitions (33.6%), promotional characters (35.3%), downloadable items (35.3%), branded games (28.6%) and designated children's sections (21.8%). Food references on popular children's websites were strongly skewed towards unhealthy foods (60.8% v. 39.2% healthy food references; Pfood references for unhealthy foods. Branded food references displayed similar marketing features to those identified on food product websites. Internet food marketing uses a range of techniques to ensure that children are immersed in brand-related information and activities for extended periods, thereby increasing brand familiarity and exposure. The relatively unregulated marketing environment and increasing use of the Internet by children point to the potential increase in food marketing via this medium. Further research is required to investigate the impact of Internet food marketing on children's food preferences and consumption, and regulatory options to protect children.

Full Text Available Exchange rate regimes and the monetary policy are the key instruments governments use to achieve their economic and financial objectives. Moreover, due to global financial crisis the latter instruments get more importance. Empirical evidences show that exchange rate regimes in Kosovo and its monetary policy throughout their development were mainly influenced by different political and historical developments. In regard of Euroisation of monetary system in Kosovo it was found that this action generated macro - financial stability in terms of inflation and price fluctuation. However, in terms of microeconomic aspects, the unilateral adaptation of Euro as the official currency of Kosovo failed to provide microeconomic advantages such as to export stimulation, and so forth. The main exchange rate regime systems were discussed focusing in their advantages and disadvantages, and it was concluded that there is no commonly accepted theory regarding the optimality of exchange rate regimes. In addition, the global financial crisis impact in the financial system of Kosovo is also discussed and it was found that negative impacts of global financial crisis were moderate and indirect.

The commercialization of food irradiation in Japan was started in 1973 for the sprout inhibition of potatoes as the first successful food irradiation facility in the world. Since approval of potato irradiation, no items has been commercialized in Japan. However, international agreement for phase out of methyl bromide after 2005 and increasing incidences of foodborn diseases such as by Escherichia coli O157:H7 are forcing to have interesting to food irradiation. Takasaki Radiation Chemistry Research Establishment has long experiences on research of irradiation effect and engineering of food irradiation in Japan. From these back ground, working group of food irradiation was organized at August 1997 by some members of Department of Radiation Research for Environment and Resources and Advanced Technology Center for supporting technically on commercialization of food irradiation. This report presents the result of discussion in working group on generalization up to date researches of food irradiation, application fields and items, technical problems and future prospects of this technology in Japan.

Background/Aims Persistent incidents of food fraud in China have resulted in low levels of consumer trust in the authenticity and safety of food that is domestically produced. We examined the relationship between the concerns of Chinese consumers regarding food fraud, and the role that demonstrating authenticity may play in relieving those concerns. Methods A two-stage mixed method design research design was adopted. First, qualitative research (focus groups n = 7) was conducted in three Chinese cities, Beijing, Guangzhou and Chengdu to explore concerns held by Chinese consumers in relation to food fraud. A subsequent quantitative survey (n = 850) tested hypotheses derived from the qualitative research and theoretical literature regarding the relationship between attitudinal measures (including risk perceptions, social trust, and perceptions of benefit associated with demonstrating authenticity), and behavioral intention to purchase “authentic” European products using structural equation modelling. Results Chinese consumers perceive food fraud to be a hazard that represents a food safety risk. Food hazard concern was identified to be geographically influenced. Consumers in Chengdu (tier 2 city) possessed higher levels of hazard concern compared to consumers in Beijing and Guangzhou (tier 1). Structural trust (i.e. trust in actors and the governance of the food supply chain) was not a significant predictor of attitude and intention to purchase authenticated food products. Consumers were shown to have developed ‘risk-relieving’ strategies to compensate for the lack of trust in Chinese food and the dissonance experienced as a consequence of food fraud. Indexical and iconic authenticity cues provided by food manufacturers and regulators were important elements of product evaluations, although geographical differences in their perceived importance were observed. Conclusions Targeted communication of authenticity assurance measures, including; regulations

Based on the hierarchical equations of motion approach, we study the time-dependent transport properties of a strongly correlated quantum dot system in the Kondo regime (KR), mixed valence regime (MVR), and empty orbital regime (EOR). We find that the transient current in KR shows the strongest nonlinear response and the most distinct oscillation behaviors. Both behaviors become weaker in MVR and diminish in EOR. To understand the physical insight, we examine also the corresponding dot occupancies and the spectral functions, with their dependence on the Coulomb interaction, temperature, and applied step bias voltage. The above nonlinear and oscillation behaviors could be understood as the interplay between dynamical Kondo resonance and single electron resonant-tunneling.
Introduction of a novel food processing technology- food irradiation

The treatment of food with ionizing radiation for its preservation is a resurging technology which was lying dormant since its introduction after the discovery on the use of x-ray as an effective way to kill bacteria in food. Large research programmes were initiated on the use of gamma rays for food preservation in many countries and some of the conclusions derived are discussed. 1 fig., 2 tabs
