Food comes after air and water in terms of importance in the survival of human beings, In addition, it is the support and strength of health and support, if lost or destroyed man would die or get sick and become a heavy burden on himself and his society. Food, like other sources of life, is subject to various risks and corruption comes from countless sources. Among these dangers is the result of spontaneousness, lack of knowledge or compulsion due to the interaction of variables beyond the will of the producer and the consumer, such as pollution of water, air and environment and their reflection on food consumed by people. However, we can’t deny that some reasons of corruption are intentional and resulting from a planning in advance in order to make an illegal profit at the expense of people's health and safety. The importance of provision of food these days has increased as the number of sources of fraud and manipulation of its components has increased, not to mention the variety of cheating and scamming methods that accompany it from the factory until it reaches the consumer. Increasing the population and increasing the need to feed millions of people in different countries of the land led to an increase in quantities of materials transferred, pre-processed and packed, which are prepared through complex manufacturing processes and go through multiple hands starting from the farm to shipping then factory and storage and finally supply in the wholesale and retail markets. There is no question that all those who follow the food chain have interests and goals that come primarily from profit. It is not surprising that many of them seek to maximise their personal benefit and avoid potential losses, even at the expense of consumers. Here comes the role of the important mediator in the transfer of knowledge and warning, which warns of dangers resulting from consumption of adulterated food and there is no doubt that various media are the main role of this mediator in contemporary society. A thorough understanding of consumer behavior will provide marketing managers with a better idea of how marketing activity works and help them develop a more efficient and capable marketing strategies. Predictability of consumers' behavior and purchasing motivations that reflect their desires and needs will help develop appropriate marketing policies. Future consumer behavior can provide information and insight into consumer decisions, allowing to identify the relationship between attitudes of consumers and journalists towards the phenomenon of cheating in food. We hope this research would provide an objective picture of these trends and study the relationship between perception and knowledge of journalists about the phenomenon under study and the impact on attitudes of consumers, also to indicate the success of press in raising awareness and guidance of the audience by analyzing the press coverage of this phenomenon during the research period. This research aims to reach an answer to a number of questions related to the trends of consumers and journalists about the phenomenon of the lack of food. These questions relate in fact to the basic components of trends, specifically the behavioral and cognitive aspects and related views. The Iraqi press in the field of combating the phenomenon of cheating in food stuffs, whether through identification of the mechanism of work or through the technology of this phenomenon in 2001.
The cheif aim of the present investigation is to develop Leslie Gower type three species food chain model with prey refuge. The intra-specific competition among the predators is considered in the proposed model. Besides the logistic growth rate for the prey species, Sokol Howell functional response for predation is chosen for our model formulation. The behaviour of the model system thoroughly analyses near the biologically significant equilibria. The linear stability analysis of the equilibria is carried out in order to examine the response of the system. The present model system experiences Hopf bifurcation depending on the choice of suitable model parameters. Extensive numerical simulation reveals the validity of the proposed model.
A three species food web model involving a stage structure and cannibalism in the top predator species is proposed and studied. It is assumed that the prey species growth logistically in the absence of predator and the predation process occurred according to theLotka-Volterra functional response. The existence, uniqueness and bounded-ness of the solution of the model are investigated. The local and global stability conditions of all possible equilibrium points are established.The persistence conditions of the model are also determined. The local bifurcation near each of the equilibrium points is analyzed. The global dynamics of the model is investigated numerically and compared with the obtained analytical results. It is observed that the p
... Show MoreThe avoidance strategy of prey to predation and the predation strategy for predators are important topics in evolutionary biology. Both prey and predators adjust their behaviors in order to obtain the maximal benefits and to raise their biomass for each. Therefore, this paper is aimed at studying the impact of prey’s fear and group defense against predation on the dynamics of the food-web model. Consequently, in this paper, a mathematical model that describes a tritrophic Leslie-Gower food-web system is formulated. Sokol-Howell type of function response is adapted to describe the predation process due to the prey’s group defensive capability. The effects of fear due to the predation process are considered in the first two levels

The analysis involves a thorough literature assessment and comparison of present strategies to pinpoint key tendencies and propose novel approaches. The methodology involves examining recent technological enhance ments in video coding standards, quality appraisal methods, and compression tech niques. Specific domains investigated comprise firmware component architectures, 4D indexing structures, and iterative filtering frameworks. The study in addition weighs tradeoffs between video quality, encoding intricacy, and bitrate demands. Key determinations consist of

With the environment, the public always turns to the public broadcasting service and its programs to provide knowledge so that it can avoid it. Thus, the respondents' attitude towards this issue was positive.
Feminism is a diverse set of social theories, political movements and ethos driven by women's causes. Feminists and feminists agree that the ultimate goal is to eliminate the forms of gender-related oppression It should be noted that feminism originated at the beginning as an emancipation movement aimed only at lifting the injustice and suffering of European women, but over time evolved and crystallized to form an independent thought in itself swimming against all the universals known to humanity in the relationship between male and female nature This study posits a hypothesis that the feminist movement is characterized by multiple and varied trends, different in its analyzes of the causes of women's oppression, but all agreed on the need t

However, many difficulties that may appear about eating food can be avoided, if the family used the right way in dealing with this problem. The study aims, in this case, at searching for the reasons that lies behind the child's obstinacy in eating his food and the attempt to study some variables that is related to the research topic.
