Practical Methods for Meeting Remediation Goals at Hazardous Waste Sites

Risk-based cleanup goals or preliminary remediation goals (PRGs) are established at hazardous waste sites when contaminant concentrations in air, soil, surface water, or groundwater exceed specified acceptable risk levels. When derived in accordance with the Environmental Protection Agency's risk assessment guidance, the PRG is intended to represent the average contaminant concentration within an exposure unit area that is left on the site following remediation. The PRG, however, frequently has been used inconsistently at Superfund sites with a number of remediation decisions using the PRG as a not-to-exceed concentration (NTEC). Such misapplications could result in overly conservative and unnecessarily costly remedial actions. The PRG should be applied in remedial actions in the same manner in which it was generated. Statistical methods, such as Bower's Confidence Response Goal, and mathematical methods such as "iterative removal of hot spots," are available to assist in the development of NTECs that ensure the average postremediation contaminant concentration is at or below the PRG. These NTECs can provide the risk manager with a more practical cleanup goal. In addition, an acute PRG can be developed to ensure that contaminant concentrations left on-site following remediation are not so high as to pose an acute or short-term health risk if excessive exposure to small areas of the site should occur. A case study demonstrates cost savings of five to ten times associated with the more scientifically sound use of the PRG as a postremediation site average, and development of a separate NTEC and acute PRG based on the methods referenced in this article.     

Measuring Mutual Help Willingness and Criteria among Hong Kong People: Confirmatory Factor Analyses

Mutual help has been often found to be beneficial for people’s well-being in clinical settings. Research in the general population, however, is relatively limited, partly due to the lack of applicable measurement tools. The present study attempted to develop two scales to measure mutual help willingness and criteria and test their psychometric properties among a community sample of Hong Kong people (n = 951). Confirmatory factor analyses suggested that the hypothetical models fitted the data very well. Results also indicated that though the willingness to seek help and to give help was significantly correlated, Hong Kong people were generally more willing to give help than to seek help. Age had a negative effect on help-seeking willingness, which can not be explained by education level. A set of criteria were applied similarly when people decided on help-giving and help-seeking. Agreement with the criteria was negatively correlated with age but the associations became negligible when education level was controlled. Research and practical implications of the findings are discussed.     

Willingness to speak out about gay laws reform: some cause for optimism

We examined the extent to which people's private attitudes to gay law reform are influenced by the attitudes of others. Ninety-six university students were told that they were either in a minority or in a majority relative to their university group on their attitudes to gay law reform. Contrary to a number of assumptions made in the social psychological literature, participants who supported gay law reform were more prepared to act in line with their attitudes than were those who opposed gay law reform. Furthermore, anti-gay law reform participants appeared to reassess their attitudes when they were told they were in a minority; in contrast, pro-gay law reform participants were unaffected by the group norm. This suggests that anti-gay law reform attitudes are softer and more easily influenced than are pro-gay law reform attitudes. The implications of these results for activists are discussed.     

The Role of Coping Strategies in Understanding the Relationship Between Parental Support and Psychological Outcomes in Anxious Youth

The current study examined the moderating role of coping strategies on psychological outcomes at varying levels of parental support in a sample of clinically anxious youth. Youth (N?=?174, mean age 11.89) completed the Children’s Coping Strategies Checklist, Child and Adolescent Social Support Scale, Multidimensional Anxiety Scale for Children and Children’s Depression Inventory. Data was gathered at a large, university-based anxiety disorders treatment clinic. This nonexperimental design analyzed the use of active and avoidant coping strategies as a moderator of anxiety and depression, while controlling for parental support. Results revealed active coping strategies did moderate the relationship between parental support and anxiety, however, not as expected while the significant moderation role of avoidance coping was mixed. Findings showed that anxious youth with more parental support and more active coping were at risk for higher levels of anxiety, yet protected from higher depression. Avoidant coping strategies did moderate in a manner that was predicted for higher anxiety symptoms. Results suggest increased need for parental involvement in the treatment of anxiety disorders in youth.     

An examination of the adult day services industry using the resource dependence model within a values context

The adult day services (ADS) industry continues to grow and develop in providing care to larger numbers of older adults and their caregivers. Despite the growth in the number of programs and the changes in the way services are delivered, a systematic examination of the development of the ADS industry from a policy perspective has not been published since the mid-1990s. This article provides an analysis of the development of the ADS industry using the resource dependence model within a values-based context to determine whether public reimbursement opportunities are congruent with the needs of older adults and caregivers. Potential directions for the future development of the industry are presented through analysis of the collaborations of adult day providers with the providers of other services for older adults and the effort by public and private funders to connect quality outcomes and resources.     

Conflict or consensus: An investigation of stakeholder concerns during the participation process of major infrastructure and construction projects in Hong Kong

Public participation in the planning and design of major public infrastructure and construction (PIC) projects is crucial to their success, as the interests of different stakeholders can be systematically captured and built into the finalised scheme. However, public participation may not always yield a mutually acceptable solution, especially when the interests of stakeholders are diverse and conflicting. Confrontations and disputes can arise unless the concerns or needs of the community are carefully analysed and addressed. The aim of the paper is to propose a systematic method of analysing stakeholder concerns relating to PIC projects by examining the degree of consensus and/or conflict involved. The results of a questionnaire survey and a series of interviews with different entities are provided, which indicate the existence of a significant divergence of views among stakeholder groups and that conflicts arise when there is a mismatch between peoples’ perception concerning money and happiness on the one hand and development and damages on the other. Policy and decision-makers should strive to resolve at least the majority of conflicts that arise throughout the lifecycle of major PIC projects so as to maximise their chance of success.
