The study was conducted to determine the food consumption patterns, dietary quality and health status of expectant women and also to assess their level of awareness of nutritional requirements during pregnancy. Food beliefs, taboos and superstitions held by the women were also investigated. Using the purposive sampling technique, 30 pregnant women attending the Maternal and Child Health Clinic at Dodowa (rural) and University Hospital, Legon (suburban), were selected for the study. A structured questionnaire was used to collect information on the respondents’ nutritional knowledge, beliefs, taboos and superstitions and health status. A food frequency questionnaire and the 24‐h dietary recall method were used to obtain information on food consumption patterns and dietary quality. The study revealed that, although the majority of the respondents (83.3%) had some knowledge of nutrition, not all were applying it in their feeding practices because of financial constraints. With regard to consumption patterns, most of the women (83.3%) were having three meals a day, while the rest either ate twice a day or anytime they were hungry. Seventy‐three per cent of the respondents also increased their food intake during pregnancy. Foods eaten were based mainly on starchy roots and tubers, cereals and vegetables. Legumes, oilseeds and fruits were often lacking in the main meals of respondents. Although animal products were consumed daily, the quantities taken were very small to provide for adequate protein, especially in the rural area. Various types of food were avoided by some of the expectant mothers for reasons such as nausea, loss of appetite, taboos and superstition. With regard to dietary quality, respondents from the rural area had diets of poorer quality in terms of nutrient intake compared with those from the suburban area. In both communities, iron contents of diets were quite low. Forty‐seven per cent of the women interviewed were anaemic, with a higher prevalence of anaemia being observed in the rural community. Common ailments reported by the women were dizziness, headache, waist pains and malaria. Based on the results of the study, it was recommended that nutrition education for pregnant women should be stepped up at antenatal clinics especially in rural areas. 相似文献

Exemplification theory asserts that message components that are iconic and emotionally arousing are easily accessed, and are therefore relied upon when making subsequent behavioral decisions. A reanalysis of data from three studies collected at different times, unrelated experimental stimuli (terrorism, food ingredients, and bed bugs), different media (visual and print), varying geographic locations, different experimental conditions (laboratory and online), and diverse participants suggests that these processes work differently for men and women. Results suggest that the medium through which an exemplar is presented and/or experienced may be fairly inconsequential, but there are underlying processes which may determine the extent to which individuals will modify behavioral intentions related to risks. After witnessing exemplified portrayals, women were more likely than men to express a desire to modify behavior, perceive themselves as more susceptible to the risk, and perceive the risk as being more severe across the studies. The findings are discussed in terms of directions for future research and implications for risk communication practitioners. 相似文献

Although the Common Agricultural Policy of the European Union has broadened its objectives to integrate social issues, several hard-to-reach groups of farmers and workers continue to be ignored by advisory services and associated policies. Connecting with these groups has a strong potential to increase the economic and social cohesion of European agricultures. We interviewed over 1,000 farmers across Europe and identified features of these groups that are often overlooked by advisory services. We critically reflected on the social cohorts omitted from advisory services and how they could be better reached; they include farm labourers, new entrants or ‘career changers’, and later adopters. We clarify the different types of advisors in the advisory landscape, distinguishing between those who are linked to or independent from sales of inputs or technologies. We make concrete recommendations about how to engage advisors with hard-to-reach groups, with approaches suited to different national contexts of Agricultural Knowledge and Innovation Systems (AKIS); thus contributing to the ‘AKIS dimension of National Strategic Plans of the next Common Agricultural Policy, 2023–2027. We argue for the more effective use of advances in the social sciences through a better understanding of advice as social interaction which can bolster the inclusiveness of public policies. 相似文献

Researchers and society devote increasing interest to environmental impact assessments. The study here discusses and questions current assessment models by relating them to inter-organizational network analyses, and demonstrates that single entities as the basis for environmental impact assessments may not be in the best interests of society. Three case studies focusing on logistical solutions illustrate environmental effects on a single-entity and a network level. The paper concludes that considering environmental impacts on a single-entity level disregards indirect effects, which in turn has consequences for the environment. The paper points to the importance of identifying the appropriate level for analysis of environmental impacts since the single entity as the basis for assessments may undermine environmentally friendly intentions. 相似文献

Using data from the high-stakes 2013 Dubai professional tennis tournament, we find that, compared with a tied score, (i) male players have a higher serve speed and thus exhibit more effort when behind in score, and their serve speeds get less sensitive to losses or gains when score difference gets too large, and (ii) female players do not change their serve speed when behind, while serving slower when ahead. Thus, male players comply more with Prospect Theory exhibiting more loss aversion and reflection effect. Our results are robust to controlling for player fixed effects and characteristics with player random effects. 相似文献

Sustainable consumption is one of the major goals of the affluent European societies in their quest for sustainable development. A key player in sustainable consumption is the sustainable or green consumer. The aim of this study was to examine the profile of the Greek green consumer based on the study and empirical analysis of engagement in selected 3R (reduce – reuse – recycle) activities. In addition, the attitudes on certain issues related to sustainable consumption of the consumers were examined and analysed. Empirical analysis is based on the use of a cross‐section data set. An extensive survey of 300 Greek consumers via a questionnaire was carried out in the first trimester of 2008. The sampled households were located in five of the main and most representative regions of Athens, with respect to the socioeconomic characteristics (sex, age, income group, education level) of their residents. Respondents were asked to answer questions examining the 3R concept on daily issues such as solid waste generation and water and energy consumption. Empirical results are based on the estimation of regression models. Econometric models are estimated for each question explaining engagement in 3R activities. Empirical results suggest that sociodemographic characteristics do specify engagement in 3R related activities. In particular, age and income are the most influential factors that determine this engagement. In addition, our study reveals that four out of five Greek consumers identify global climate change as the most important issue of our time. However, only one in five of the respondents are willing to change their lifestyle in order to mitigate the negative environmental impacts of our everyday activities; compared with men, women are more willing to do so. One in two consumers report that eco‐friendly products are more expensive than standard ones. However, when questioned as to whether they would pay a higher price for products with less environmental impact, almost four out of five responded favourably. 相似文献

Toxin handlers are organizational members who help colleagues manage negative emotions in the workplace. Although toxin handling activities help distressed employees remain productive, they put the toxin handler at risk of emotional exhaustion. In this research, more than 400 HR managers described their experience managing emotionally charged employee problems. We found that formalizing toxin handling responsibilities provided a buffering effect: HR managers whose organizations had made handling emotionally charged employee problems a formal part of HR responsibilities experienced lower levels of emotional exhaustion and perceived HR as more effective, even when they engaged in high levels of toxin handling. Formalizing toxin handling responsibilities may protect HR managers from harm and ensure that they maintain the toxin handling function in their organizations. © 2009 Wiley Periodicals, Inc. 相似文献
