Genetically modified foods: Consumer awareness,opinions and attitudes in selected EU countries

The dynamic development of biotechnology in recent years has raised serious public concerns about the possible risks arising from genetically modified organisms (GMOs). The aim of this study was to investigate consumer opinions regarding genetically modified (GM) foods. The research also aimed at verifying the differences in the attitudes of respondents from two, relatively culturally diverse research sites. To obtain empirical data a face‐to‐face survey was conducted in 2015. It covered a total of 976 randomly selected individuals. The study was performed in the capital of the United Kingdom—London and the Polish capital—Warsaw. The results of the study show that almost half of the respondents were familiar with the GMO concept. According to the respondents, the greatest benefits arising from the genetic modification are: enhanced shelf‐life of food and crops' resistance to extreme climatic conditions. The main disadvantages were: unpredictable consequences of deoxyribonucleic acid (DNA) modification, production of species‐specific toxins and food allergenicity. Over two thirds of people surveyed support the idea of the obligatory labeling of GM foods. The information presented on food packaging should primarily include potential contraindications to the consumption, indication that food was produced using transgenic sources and a warning about potential allergenicity. An almost equal number of respondents showed intention for purchasing GM food products, an intention to act otherwise, or was not decided. As many as 27.7% of survey participants showed negative attitudes toward GM foods, whereas only 19.8% predominantly positive. It is worth noticing that, with only one exception, no statistically significant differences were observed between the opinions of Polish and British respondents.     

基于收费站的集装箱流失量统计

为了准确得到城市集装箱流失数据,首先建立港口城市集装箱流向模型,将城市集装箱分解成本市生成的集装箱量、港口吞吐量、流失量、流入量,然后借助公路收费站采集集装箱流失基础数据,继而利用数学统计方法对数据进行计算与修正,从而得到城市集装箱流失量。     

The Positive Externalities of Chapter 13 “Cramdowns” Could Prevent the Next Foreclosure Crisis

Revision of Bankruptcy Code 11 U.S.C. § 1322(b)(2) would permit “cramdowns” wherein bankruptcy judges would administer the modification of residential mortgages only when mortgage-lending abuses were most rampant (a real estate bubble). Foreclosure spill-over effects systemically worsened the housing crisis and were not evenly diffused throughout the broader housing market. Throughout 2003–2006, an oversupply of underpriced mortgage finance emanating from lax underwriting standards bid up residential prices. Relaxation of underwriting protocols came about from the mortgage market’s institutional swing from regulated agency securitization (predominantly government-sponsored enterprises “GSEs”) to unregulated securitization (shadow banking). This resulted in an untenable residential-price bubble as synthetically inexpensive credit from investors’ mispricing amplified mortgage demand, while greater mortgage quantity nudged up housing prices. The result was a self-referential cycle of waning residential prices supporting and perpetuating nigh incessant foreclosures: the bubble had burst. Cramdowns would incentivize lenders to be less inclined to loosen underwriting standards, or when done, to include this factor in the risk premium of the cost of credit. Enhancing Chapter 13 with the muscle to alter residential mortgages would ameliorate an institutionally structural issue endemic to the past (and upcoming?) foreclosure crisis.
