The nutrition transition in diets and health is closely tied to other aspects of economic development, including agricultural transformation and urbanization as well as demographic change and epidemiological transition from infectious to noncommunicable disease. Over time, dietary patterns typically shift from widespread inadequacy of many foods and nutrients, especially for children and mothers, into surplus energy intake and rising obesity with continued inadequacy of healthier foods. Diet‐related diseases remain the largest single cause of premature death and disability in all regions. This article combines food availability and dietary intake data from more than 100 countries over 30 years with a wide range of other evidence to characterize the nutrition transition and its association with changes in agricultural production and the food environment, asking how future dietary patterns might be steered toward healthier outcomes as national incomes grow.  相似文献

Changes in housing price affect both individuals and government since they have substantial influence on the socio‐economic conditions. Valuations of housing are necessary in order to assess the benefits and liabilities in housing sector. This study presents a flexible meta‐modelling approach for improvement of housing price estimation in ambiguous and complex environments. It is composed of artificial neural network (ANN) and fuzzy linear regression (FLR). Seven FLR models are considered to cover latest approaches and viewpoints. Also, ANN is applied to data sets. The preferred FLR model is selected via mean absolute percentage of error (MAPE) for further considerations, and then the preferred FLR model and the best structure of ANN are applied to the data set. Finally, the preferred model is selected based on MAPE. The intelligent approach of this study is applied for estimation and forecasting housing price in Iran. The housing price in Iran mainly is based on eight economic indices including currency, oil income, general index, house service pricing index, rate of informal market, gross domestic production in basic price, added value of oil group and construction materials price. FLR is identified as the preferred model with lowest MAPE for housing price forecasting in Iran. This shows that the housing market of Iran is associated with severe environmental fuzziness and ambiguity. This is the first study that introduces a flexible neuro‐fuzzy approach for improved estimation and forecasting of housing price in noisy, complex and uncertain environments.  相似文献

In many countries, babies born to women in prison stay in prison with their mother and very young children may accompany their mothers in prison. Among these countries, Iran is one of those we do not have enough information about its prisoners especially mothers who have child(ren). This study aims to investigate imprisoned mother–child interaction by a qualitative method, Grounded Theory, in Iran. Two main questions of this research are: how is the interaction of mother–child in prison? What are the consequences of this interaction? Participants of this study comprised of 14 imprisoned mothers who were on leave, Iran. Being a mother and living with a child was the criterion of selecting the participants. All of the participants were in a separated unit. Data analysis yielded six categories and a core category. The categories are: “child as an emotional support of the mother; child as centre, prison as periphery; hope and will to favored future; mother unit as a family; rehabilitation; the other side of the coin: perceived risk for children.” Core category of the study is “imprisoned mother–child interactions: learning to live by hope and fear.”  相似文献

The number of incarcerated mothers is increasing significantly. There are many risks and harmful consequences for the children of the incarcerated mothers. In Iran, there is not a systematic research and information on these children. Therefore, this study aims at utilizing a qualitative methodology, to investigate the living conditions of this group, based on their mothers’ narratives. The grounded theory approach of Strauss and Corbin 1998 was used to analyze the consequences of the incarceration of mothers on the living conditions of children. The participants of the study include 16 incarcerated mothers who were on leave. The data were gathered via in-depth and open-ended interviews. During the coding process six categories were extracted which describe the living condition of the children: behavioral, mental, and physical challenges; escape; experience of poverty and destructive economy of family; dilemma of caring; mother-child visitation; difficulties suicide and mother’s emotional challenges. Children of incarcerated mothers encountered challenges such as mental, behavioral and economic. Many of them escape from home and school. Mothers prefer informal caring of their children than formal. The mother-child visits include some difficulties such as long distance, transportation costs, and undesirable visiting atmosphere. Mothers pointed to their deep psychological problems and sometimes committing suicide due to the separation of their children.  相似文献

This study aims to examine the sociological aspects of the phenomenon of women self-immolation in Lorestan, Iran. The methodology of ‘Grounded Theory’ was used to analyze data gathered from 11 women who had attempted self-immolation. Data analysis yielded ten categories including patriarchy, divorce as a stigma, family maladjustment, economic frustration, access to fire, prevalence of self-immolation, self-immolation for emancipation, self-immolation as a threat, reorganization of social relations, and remorsefulness. Generally, in societies where patriarchy is dominant, divorce is considered a stigma, and life style pattern is pastoral or rural, when family maladjustment and economic frustration emerge as well, the occurrence of the phenomenon of women self-immolation becomes more likely.  相似文献

This study was carried out to investigate reasoning and interpretation of motorcyclists for not using helmet utilizing qualitative methodology of ‘grounded theory’. The field of the study was Kerman, a cultural-historical city at the south-east of Iran. Participants were 21 young male motorcyclists. Two sampling strategies were used: maximum variation and snowball sampling. To collect data, in-depth, open-ended interviews were conducted. Data analysis yielded seven categories: fatalism; a barrier to social relationships; peer group pressure and negative labelling; messing up the appearance; disturbance in hearing and vision; barrier to normal breathing; and heaviness and superfluity of helmet. Based on the findings of the current study, it could be concluded that socio-cultural contexts, motorcyclists’ worldview and partly helmet-related problems are of the main factors which affect motorcycling. Therefore, the studies, policy-makings, and intervening programmes to control injury and to promote safety among motorcyclists should be focused on socio-cultural barriers to helmet use in general and changing the motorcyclists’ standpoints toward fatalism in particular. Helmet-related problems should be considered, too.  相似文献

The purpose of this qualitative study was to examine leisure as a context for identity formation among the high school students in Shiraz, Iran. Twenty male students (3rd grade of secondary school) from different high schools participated in this study. Data analysis using qualitative grounded theory methodology yielded eight categories and a core category. The categories led to the conclusion that post-traditional context and resource of leisure time culminated in reflexivity in the participants’ identity.  相似文献
