有这样一个故事:一位老妇失眠,吞下一粒安眠药才能入睡。有一天晚上,老妇跑来敲邻居吉姆的门说:“吉姆,很抱歉打扰你,我睡不着,而且安眠药刚吃光了,不知你身边是否还有安眠药?”吉姆很快回答:“太太,我有安眠药,放在楼下。我这就下楼去... 有这样一个故事:一位老妇失眠,吞下一粒安眠药才能入睡。有一天晚上,老妇跑来敲邻居吉姆的门说:“吉姆,很抱歉打扰你,我睡不着,而且安眠药刚吃光了,不知你身边是否还有安眠药?”吉姆很快回答:“太太,我有安眠药,放在楼下。我这就下楼去找一粒给您。”然后,吉姆很快地冲到楼下,跑到食品室去取了一粒大青豆。他知道这位太太视力不佳,无法辨别青豆与安眠药。他回到楼上,说:“这是一颗特大号的安眠药,很管用。服下很快就会入睡了。”这位老妇人当真服下了这颗“药丸”,而且睡了她这一生中最好的一觉。 这就说明一种思想进入心中,它会盘踞成长。作为灵魂的工程师,我们应该像吉姆那样,让积极的种子进入学生的心中,使他们早日树立信心,获得进步,这是我们义不容辞的责任。 展开更多

The polysemous character makes it sensitive and complex phenomena. For instance, value that is acceptable in the western part of Nigeria may be unacceptable in the north or east. This clearly implies that value, although may be of the people, is relative and subjective. This study made use of survey research design with a single research question set to guide it. Data were collected from 362 respondents who were purposively selected in the study area (Lagos State, Nigeria) as sample size. Data gathering were done on the field with the aid of questionnaire and analyzed with descriptive statistics. Specifically, a Table of frequency and percentage distribution was employed and scoring of variables was done vis-h-vis the responses of the consumers of staple commodities to look at the extent to which societal values have influenced product advertisements in the State. The Mean and standard deviation was calculated. The result of the study presented in Table 1 shows that all the societal values scoped for this study (culture, moral, religion, taste, language and color) influence consumers in one way or the other but the portrayal of religious design concept to influence consumers to patronize staple commodities ranked best of all. The study observed that of all the societal values traceable to advertising campaign in Lagos State, religion-inclined advertising designs are gaining a rising number of influences. It therefore concludes that religious and cultural designs, when appropriately applied help outdoor advertising to thrive well in Lagos State. 展开更多

Rapid economic growth, increasing populations and emergent prosperity are driving up demand tor energy, water anu food, especially in developing countries. In this scenario, the analysis of these three elements has gained the increasing attention globally in research, business and policy spheres. This paper aims to provide an analysis of the perspectives of this nexus for Brazil and the United States, using current and predicted scenario for 2050. Considering the importance of renewable sources of energy to overcome these challenges and diversify the energy matrix in both countries, the paper will also present the biogas potential for both countries, which provides multiple economic, environmental and social benefits, such as electrical, thermal and vehicular energy, high-quality biofertilizer, reduction of odor and pathogenic vectors in the farms, decrease of ground and surface water pollution, promotion of new income for the farmers, reduction of the greenhouse gases emissions, among others. 展开更多

The resultant climate change on sustainable food supply has greatly affected agricultural production by the level of great volumes of gasses emitted into the atmosphere by human activities. The human factors that emit large amount of green house gases include industrialization, burning of fossil fuel and gas flaring. Increase in air temperature and consequent increase in the rates of evaporation also affect the level of food supply. Data for this study were collected from primary and secondary sources. Primary source were collected through field investigation and structured questionnaire. A total of 450 questionnaires were administered. Results revealed that varieties of crops ranging from tree crops to cereals were cultivated within the study area. The effect of climate change on food supply has resulted into change in crop yields, change in rainfall pattern, soil loss and has greatly affected planting period and harvesting. The study therefore recommended awareness campaigns on the causes and consequences of global climate change on food production, environmental education and afforestation campaign programmes on sustainable food supply and environmental safety must be intensified. 展开更多
