| 1 | Synchrotron micro-scale measurement of metal distributions in Phragmites australis and Typha latifolia root tissue from an urban brownfield site显示文摘Liberty State Park in New Jersey,USA,is a 'brownfield' site containing various levels of contaminants.To investigate metal uptake and distributions in plants on the brownfield site,Phragmites australis and Typha latifolia were collected in Liberty State Park during the growing season(May–September)in 2011 at two sites with the high and low metal loads,respectively.The objective of this study was to understand the metal(Fe,Mn,Cu,Pb and Zn)concentration and spatial distributions in P.australis and T.latifolia root systems with micro-meter scale resolution using synchrotron X-ray microfluorescence(μXRF)and synchrotron X-ray computed microtomography(μCMT)techniques.The root structure measurement by synchrotron μCMT showed that high X-ray attenuation substance appeared in the epidermis.Synchrotron μXRF measurement showed that metal concentrations and distributions in the root cross-section between epidermis and vascular tissue were statistically different.Significant correlations were found between metals(Cu,Mn,Pb and Zn)and Fe in the epidermis,implying that metals were scavenged by Fe oxides.The results from this study suggest that the expression of metal transport and accumulation within the root systems may be element specific.The information derived from this study can improve our current knowledge of the wetland plant ecological function in brownfield remediation. | Huan Feng Yu Qian Frank J.Gallagher Weiguo Zhang Lizhong Yu Changjun Liu Keith W.Jones Ryan Tappero | 2016 | Journal of Environmental Sciences2016，28，3： | 3 |

| 3 | Net Pension Liability Impact on School Districts after Incorporation of Governmental Accounting Standards Boards (GASB) Statement Number 68显示文摘This paper analyzes twenty school districts in the state of Pennsylvania and applies ratio analysis to understand the potential effect of GASB number 68 on the financial statements of these entities.The financial statements were picked on a random basis from the Electronic Municipal Market Access[1]database.EMMA is a research and data retrieval system of the Municipal Securities Rulemaking Board(MSRB).The MSRB provides resources to trade municipal bonds and access to the financial statements of entities selling these securities.The paper was developed as a result of the requirement by GASB to“recognize their long-term obligation for pension benefits as a liability for the first time,and to more comprehensively and comparably measure the annual costs of pension benefits”[2].The public schools in Pennsylvania incorporated GASB number 68 for the fiscal year ended June 30,2015 and restated the financial statements for the fiscal year ended June 30,2014.The effects of these restatements created a situation where most of these districts now show a negative fund balance caused by an increase of liabilities of over one hundred percent.Many of the decision makers are uncertain of the long-term changes that this recognition will have on the operations of the school district.Bond ratings have suffered because of the volatility and uncertainty causing negative effects on the balance sheet,increased current recognition of pension expenses,and a possible interest rate increase.All of these effects are illustrated in this paper.This is at a time where many people are questioning the performance of many of the school districts. | Michael J.Gallagher Emily F.Gallagher | 2019 | Journal of Business Administration Research2019，2，1： | 1 |
