Environmental values and willingness to pay for a protected area: a segmentation of Italian university students

The study investigated students’ attitudes and willingness to pay (WTP) for the protection of some environmental values. The empirical study refers to a site located in Southern Italy and inserted into the Natura 2000 European Network. Students were segmented according to their appreciation of environmental values and the WTP for them. We considered two scenarios of the study site – of use and non-use – and four values – recreational, educational, bequest and existence. Five clusters, from the ‘unconcerned’ to the ‘committed’ one, reveal a diversity of profiles across the sample. Segmentation results point out the multifunctionality of the environmental heritage and highlight the heterogeneity of students’ environmental profiles.     

A／O-MBR工艺处理校园生活污水中水回用工程的设计与运行

针对Et处理量为1500m3的高校中水处理设施，论述了缺氧／好氧-MBR（A／O—MBR）处理工艺运行特性，完成了长效监测及经济性评价。系统MBR池污泥浓度（MLSS）控制在8～12g／L，缺氧池和好氧池水力停留时间（HRT）分别为3h和7h，污泥回流比为200％～300％。当进水COD、总氮、氨氮平均浓度分别为481．3、75．1和65．8mg／L时，出水COD、总氮、氨氮平均浓度分别为16．5、13．4和0．7mg／L，平均去除率分别为96．4％、81．9％和99．0％。在进行化学除磷的情况下，出水总磷的平均浓度为0．8mg／L，平均去除率86．5％。出水水质优于《城市污水再生利用城市杂用水水质》（GB／T18920—2002）中的相应水质指标要求。经济性分析结果显示，该中水站的电耗为0．58kWh／m3。     

The theory of planned behavior (TPB) and texting while driving behavior in college students

Objective: To examine the role of intent and other theory of planned behavior (TPB) constructs in predicting college students' willingness to text while driving (TWD).

Methods: This was a cross-sectional study. 243 male and female college students enrolled in the 2013–2014 academic year in the College of Health, Human Services & Nursing completed a survey on TWD. Inclusion criteria: All races and ethnicities, ≥18 years of age, cell phone owner, and licensed driver.

Results: Over 70% of the sample (n = 243) reported talking on a cell phone and sending and receiving text messages “at least a few times” while driving within the past week. However, only 27% reported being stopped by police. Of these, 22% reported being fined. Within the past 30 days, 26% reported reading or sending TWD and having to slam on the brakes to avoid hitting another car or pedestrian(s) as a result. In all, 47% of the variance in intention to send TWD was accounted for by the full TPB model. Intention, in turn, predicted willingness to TWD. Intention also mediated the relationship between perceived behavioral control and willingness to TWD.

Conclusion: Attitude was found to be the strongest predictor of intention. In addition, intention was found to mediate the relationship of willingness to TWD on perceived behavioral control. These findings highlight potential factors that could be targeted in behavioral change interventions seeking to prevent TWD.
