Beyond the urban stream syndrome: organic matter budget for diagnostics and restoration of an impaired urban river

In response to water quality standard violations linked to excessive organic matter (OM) and a lack of sampling data informing the Total Maximum Daily Load (TMDL), an organic matter budget was created to quantify and identify sources of OM in the lower Jordan River (Salt Lake City, UT). By sampling dissolved, fine and coarse particulate OM, as well as measuring ecosystem metabolism at seven different sites, the researchers aimed to identify the origin of excess OM, and understand pathways by which different size classes of the OM pool are generated. The dissolved fraction (DOM; 94 %) was found to be the dominant form of OM transported within the river with fine particulate organic matter (FPOM; 6 %) the second most abundant, and coarse particulate organic matter (CPOM; 1 %) transport relatively insignificant in the overall OM budget. Primary production exceeded respiratory losses in the upper river, and this, along with OM inputs from two tributaries (where water reclamation facilities discharge into the river) delivered excess OM to the impaired lower reaches. Increasing stream metabolism index (SMI) with distance downstream (>1 in the lower river) further demonstrated that transport of excessive organic matter into the lower river was from upstream sources and not due to lateral inputs. This simple approach to characterizing the organic matter budget as it relates to water quality in the Jordan River was effective and could serve as a model for future studies attempting to quantify and identify sources of OM in urban ecosystems.     

Capacity and Solidarity: Foundational Elements in the Unionization Strategy for Immigrant Day Labourers

Recent scholarship has been reasonably optimistic about unionization as a mechanism of labour justice for immigrant workers in casual and contingent work. This optimism rests on two assumptions: (1) that unions have the capacity to absorb immigrant workers in nonstandard work and (2) that casual, immigrant labourers enjoy the kind of solidarity that underpins collective action. This paper examines these assumptions critically through a case study of construction unions and Latino immigrant day labourers in Denver, Colorado and Baltimore, Maryland. I use participant observation and in‐depth interviews with nine labour unions, 19 Latino immigrant day labourers, and two (non‐union) day labour organizing projects in the cities to examine questions of capacity and solidarity. I find that the existing foundations for unionizing day labourers may be weak in certain cities and communities. Union capacity is undermined by structural fragmentation and specialization in market segments that are inaccessible to day labourers. Strategically, in an age of de‐unionization, unions also face pressures to “add value” for employers by sorting the workforce into high quality and low quality categories. Locals indicate day labourers would likely fall into the latter category, thus precluding membership. The foundations for solidarity are similarly weakened in the cases studied. Culturally, day labourers in Denver and Baltimore emphasize self‐reliance and material well‐being over collective action and the pursuit of justice. To work toward unionization, organizers should be prepared to confront deficits of capacity and solidarity in other cities as well, especially those where homelessness is prevalent among day labourers, where immigrant populations are newly arrived, or where local union cultures are unreformed. I suggest that union collaboration, a cooperative type of occupational unionism, and commitments to training day labourers may help boost union capacity to absorb day labourers, while the creative use of material incentives should figure prominently in organizing strategies.     

Listening Environment and the Bottom Line: How a Positive Environment Can Improve Financial Outcomes

Amidst the onslaught of communication at work, employees’ voices can be neglected in favor of the bottom line. This research initiates an exploration of the relationship between employee perceptions of the listening environment at work and organizational financial performance indicators. In this exploratory pilot study, we collected data from N = 65 employees of a single firm with multiple geographically and financially independent units. Using simple regression analysis, researchers compared data between units to determine if employee perceptions of positive qualities of the listening climate are related to improvement in sales and net income. Results suggest a potentially positive relationship between employees’ perceptions of a positive listening environment and these organizational performance indicators, suggesting that listening is an important step in building the communication climate of a productive company.     

Interactive Hazards Education Program for Youth in a Low SES Community: A Quasi‐Experimental Pilot Study

A pilot study of an interactive hazards education program was carried out in Canberra (Australia), with direct input from youth participants. Effects were evaluated in relation to youths’ interest in disasters, motivation to prepare, risk awareness, knowledge indicators, perceived preparedness levels, planning and practice for emergencies, and fear and anxiety indicators. Parents also provided ratings, including of actual home‐based preparedness activities. Using a single group pretest‐posttest with benchmarking design, a sample of 20 youths and their parents from a low SES community participated. Findings indicated beneficial changes on a number of indicators. Preparedness indicators increased significantly from pre‐ to posttest on both youth (p < 0.01) and parent ratings (p < 0.01). Parent ratings reflected an increase of just under six home‐based preparedness activities. Youth knowledge about disaster mitigation also was seen to increase significantly (p < 0.001), increasing 39% from pretest levels. While personalized risk perceptions significantly increased (p < 0.01), anxiety and worry levels were seen either not to change (generalized anxiety, p > 0.05) or to reduce between pre‐ and posttest (hazards‐specific fears, worry, and distress, ps ranged from p < 0.05 to < 0.001). In terms of predictors of preparedness, a number of variables were found to predict posttest preparedness levels, including information searching done by participants between education sessions. These pilot findings are the first to reflect quasi‐experimental outcomes for a youth hazards education program carried out in a setting other than a school that focused on a sample of youth from a low SES community.

Attention and Executive Functions as Mediators of Attachment and Behavior Problems

The purpose of this study was to provide a more comprehensive understanding of the relation between early parent‐child interactions and subsequent behavior problems and how certain cognitive processes mediate this relation. Specifically, this study investigated whether attention, inhibition, and planning skills mediate the relation between attachment security and behavior problems. Data were collected as part of the National Institute of Child Health and Development‐Study of Early Child Care and Youth Development when children (N = 1004) were between 36 months and the third grade. Results from structural equation models indicated that sustained attention mediated the relation between disorganized attachment and social problems. Planning mediated the relation between disorganized attachment and subsequent thought problems, attention problems, and delinquent behavior. Avoidant, ambivalent, and disorganized attachment directly predicted several behavior problems. Implications for theory and future research are discussed.     

Impact of Parenting Behaviors on Recent Alcohol Use Among African American Students

Parenting is a critical factor in substance abuse prevention. Positive parenting behaviors are identified as a protective factor for substance abuse among youth. Limited research exists that investigates the role of parenting practices on minority youth substance use. The present study seeks to examine correlates between parenting and recent alcohol use among African American youth. Specifically, to what extent do African American students report experiencing specific parenting behaviors that are measured by the National Household Survey on Drug Use and Health?, do specific parenting behaviors increase the risk of recent alcohol use among African American youth?, does the impact of parenting behaviors on recent alcohol use among African American youth differ based on sex (males and females) and age category (12–13, 14–15, and 16–17 years old) were examined in this study? Logistic regression analysis of the National Household Survey on Drug Use and Health was conducted to examine the research questions. Findings indicated that parenting behaviors was associated with recent alcohol among youth. Significant differences were found for males, females, 12–13, 14–15, and 16–17 years olds. Study findings demonstrate the importance of positive parenting behaviors in youth alcohol prevention. Program specialists may target parenting as a means of preventing and reducing youth alcohol use among African American youth.     

Discursive psychology as a method of analysis for the study of couple and family therapy

The field of couple and family therapy has benefitted from evidence generated from qualitative approaches. Evidence developed from approaches relying on language and social interaction using naturally occurring recordings of real‐world practice has the benefit of facilitating practice‐based recommendations and informing practice. The aim of this article is to provide an overview of one approach to discourse analysis, Discursive Psychology (DP), demonstrating how a social constructionist framework and focus on discourse can provide an important contribution to the field of therapy. To illustrate the methodological decision‐making process for researchers and/or practitioners who utilize DP, we draw upon a video‐recorded therapeutic session involving Tom Andersen. To conclude, we make recommendations for practitioners using DP to explore and examine therapeutic practice.
