Assessment of the environmental sustainability of restaurants in the U.S.: The effects of restaurant characteristics on environmental sustainability performance

ABSTRACT

This paper investigated the current levels of environmental sustainability in restaurants across the U.S. to determine whether a restaurant’s proclivity for environmental sustainability depended on its characteristics such as chain affiliation or restaurant type.

A web-based survey was administered to 2,500 top-level restaurant managers, from which a total of 218 responses were judged as usable. The data were analyzed using independent

sample t-tests and ANOVA. This study presents an in-depth account of the environmental sustainability in restaurants across the U.S. based on an evaluation of top-level managers. This study also highlights the differences in restaurant environmental sustainability across different restaurant segments.     

Separate waste collection in mountain municipalities. A case study in Campania

This paper aims to analyse the impact of land characteristics (i.e. altimetry and housing dispersion) on separate waste collection, with a focus on mountain municipalities. The high spatial heterogeneity of the driving factors of separate waste collection allows traditional techniques, such as OLS, to offer only a partial depiction of the situation, missing important information. In this view, we perform the Geographically Weighted Regression (GWR), which allows to control for the local determinants of waste management. Our data cover 550 municipalities of Campania, in Southern Italy. We control for a set of morphological and socio-economic variables, drawn from official records for 2012. Our results show that the relationships between land characteristics and separate waste collection are not constant over space. Moreover, they suggest that in the presence of non-modifiable factors (such as land characteristics) local governments should act on citizen motivations, promoting awareness on environmental issues, and should implement time-saving collection methods.     

Environmental taxes,reforms and economic growth: an empirical analysis of panel data

This paper explores the relationship between environmentally related taxes and the economic growth rate. The analysis also investigates whether this relationship differs between countries that have implemented environmental tax reforms (ETRs) and those that have not. Using panel data from 31 OECD countries over the period 1994–2013, the paper finds that when we allow environmentally related tax revenues to interact with an initial level of real GDP per capita, the overall revenues of these taxes are negatively associated with the economic growth rate in the short and long term. Furthermore, we show that the higher the initial level of GDP per capita, the more environmentally related tax revenues can promote the economic growth rate. The analysis also reveals that the relationship between environmentally related tax revenues and economic growth varies between countries that have a mechanism to redistribute environmentally related tax revenues and those that do not.     

创新网络领域知识主题研究述评

在知识经济时代，创新网络在企业创新中扮演着重要角色，而研究网络中知识要素的产生、传播、吸收等问题对了解企业网络化创新具有重要意义。基于国内外核心文献数据库，收集创新网络领域知识要素相关文献，并结合文献计量分析方法，对该领域近30年有关知识主题研究的演化规律、整体趋势等进行梳理。结果表明，国内外研究年度发文量均呈现3个阶段变化趋势，且分别拥有各自重要载文期刊，国内研究已形成核心团队，而国外并未形成；国内外研究既有相同之处，也存在差异性，且均形成较为清晰的研究框架；在演化规律上，国内横向拓展和纵向深化研究特征显著，而国外更加注重纵向深入探索分析，研究内容也更加分散；在未来前沿热点分析上，中外学者关注内容既有相同点，也有不同点，知识协同、知识惯例、企业数字化转型对知识影响的研究是未来关注重点。     

Country-level Accounting Enforcement and IPO Underpricing

Using a sample of up to 2,503 initial public offerings (IPOs) in 32 countries from 2011–2017, we predict and find that higher levels of country-level accounting enforcement are associated with lower levels of IPO underpricing. IPOs in countries with a relatively low accounting enforcement score (second quintile) exhibit a mean underpricing of 19%, whereas the mean underpricing amounts to just 9% in countries with a relatively high score (fourth quintile). The results remain qualitatively the same when we employ a multi-level model or a difference-in-difference design. In countries that substantially strengthened their accounting enforcement in the 2003–2009 period, the level of IPO underpricing decreased significantly. We show that accounting enforcement matters for the cost of going public.

2020年河北省蔬菜监督抽检数据分析

目的:分析2020年河北省市场监督管理局发布的蔬菜监督抽检数据.方法:下载2020年河北省市场监督管理局发布的食品抽检相关通告,从蔬菜品种、蔬菜细类、不合格蔬菜检出详情及不合格项目等方面进行分析.结果:1199批次蔬菜10个蔬菜品种中,检出62批次不合格,平均不合格率为5.17％.鳞茎类蔬菜、芽菜类蔬菜等不合格率较高,不合格突出的蔬菜细类为韭菜、豆芽、芹菜等,不合格项目主要为农药残留,且禁用农药残留占总不合格项次的50％.结论:河北省蔬菜质量安全水平相对较好,但低于全国平均水平,超剂量使用农药、违规使用禁用农药仍是蔬菜质量安全的主要问题,仍需加强韭菜、豆芽、芹菜等高风险蔬菜的监管力度.     

长三角地区经济增长与环境污染再研究——基于分位数回归方法

运用刻画不同区段边际变化影响的分位数回归方法,对长三角地区经济增长与废水排放关系进行实证检验,得出以下结论:1)长三角地区废水染排放与经济发展呈现同步递增关系,环境库兹涅茨倒U关系在长三角地区并不成立;2)分位数回归分析表明,高收入水平对应相对低的边际排放,随着收入增加长三角地区废水排放增速放缓;3)产业结构、城市化、技术水平等对废水排放的影响随分位点增加呈现递减趋向。
