In the Summer of 2011 The Free Library of Philadelphia (FLP) hired 90 teenagers into its six-week Summer Reading Literacy Coach Program (SRLCP) as Teen Literacy Coaches (TLCs). Data was collected at Time 1, Time 2 and Time 3. The two study hypotheses were: (1) there will be a significant improvement in TLCs personal development skills from Time 1 to Time 3 and (2) demographic data and program specific skills measured at Time 2 will account for significant variance in each Time 3 personal development skill beyond the Time 1 personal development skills. We did not find support for H1 but did find support for H2. Specific to H2 we found that team-related and higher education interest each had a significant positive impact (p

PurposeBy integrating insights from cognitive style literature and person-environment fit theory, our study aims to explore which type of entrepreneurs are more inclined to initiate humor behaviors, the circumstances under which such behaviors are more likely to be employed within entrepreneurial teams and the specific benefits of humor behaviors for initiators.Design/methodology/approachThis paper analyzes humor behaviors in entrepreneurial teams through a three-wave time-lagged field survey of 227 entrepreneurs in China.FindingsWe find that entrepreneurs with higher creating style are more likely to exhibit humor, making them more popular within entrepreneurial teams. Additionally, the positive relationship is amplified in the presence of high levels of conflict.Originality/valuePrevious studies provide substantial evidence of the positive effects of humor behaviors on their recipients in the workplace; however, there has been limited focus on the antecedents of humor behaviors and the benefits for the humor initiators. Our study addresses the gaps by providing empirical evidence that creating style of entrepreneurs may promote humor behaviors, particularly in the context of conflicts within entrepreneurial teams, and such behaviors could elevate entrepreneurs' social acceptance within teams.

The usage of pesticides is deemed essential to ensure crop production for global food security. Conventional chemical pesticides have significant effects on ecosystems. Nanopesticides are increasingly considered an emerging alternative due to their higher efficiency and lower environmental impacts. However, large knowledge gaps exist in the public perceptions and willingness-to-pay (WTP) for nanopesticides. Thus, we conducted a regional survey of pesticide users and food consumers on perceptions and WTP for nanopesticides across China. We found that 97.4% pesticide users were willing to pay for nanopesticides, with a main price from 25% to 40% higher than for conventional pesticides. Experience with applying pesticides, income, familiarity with and attitude toward nanopesticides, and trust in industries were significant determinants of WTP. Although the public were not familiar with nanopesticides, they had positive attitudes toward their future development and supported labeling nanoscale ingredients on products. Pesticide users presented high trust levels in governments and industries, while 34% of food consumers neutrally or distrusted industries in selling and production. This study highlights the socioeconomic and technological aspects of nanopesticides, which could provide guidance for industries to develop market strategies and for governments to design relevant regulation policies effectively, contributing to crop yield improvement and sustainable agriculture.

Since rural reforms in the 1980s, both the state and local governments of China have devoted great efforts to combating desertification through a number of eco-environmental restoration campaigns, resulting in burgeoning contention at all levels of government and sparking public concern. Monitoring and accurately assessing the statuses and trends of grassland desertification are important for developing effective restoration strategies. The Horqin Sandy Land (HSL), a very typical desertified grassland (DG) with better hydrothermal conditions among sandy lands in north China, was recently selected (1985–2013) to assess the spatiotemporal dynamic performances of grassland desertification before and after implementing restoration projects. Landsat images (TM/ETM+/OLI), field investigations and expert review were integrated to form a classification scheme for the HSL. Then, spectral mixture analysis and the decision-tree method were used to extract bare-sand ratios and vegetation cover fraction dynamics. A favourable phenomenon of DG was seen to be reversed in an accelerated pace during 2001–2013, despite challenge from both climatic and anthropogenic factors. However, overexploitation of grassland (especially for farming) and ground water for irrigation has led to remarkable decreases in the ground water level in recent decades, which should be highly concerning regarding the formulation of restoration campaigns in the sandy land.
