Remote and in situ photogrammetric history of the Kidd Copper tailings site,Sudbury, Ontario

There is much concern regarding the genesis of acidic leachate by mine tailings and its potential impact on local water systems. Genesis of the leachate and its subsequent escape into the surrounding watershed is controlled by the primary distribution of facies within the tailings pond. Leachate generation and percolation is enhanced in high-sulphide coarse-grained sands, while percolation is restricted in fine-grained clays formed from bentonitic slimes. The Kidd Copper deposit, located on the South Range of the Sudbury Basin, was a typical offset dike nickel deposit, where mining took place between 1970 and 1990. Using a sequence of temporally separate aerial photographs dating from 1945 to 2002, it is possible to document the initial development of the mine, its closure and the subsequent degradation of the mine tailings waste that was produced during mining activity. Since the mine's closure, the resulting tailings deposit has progressively oxidized, generating acid-rich leachate. Leachate can escape from the tailings via surface run-off and subsurface flow. The spatial distribution of possible flow pathways was mapped using a combination of sub-centimetre-resolution real-time kinematic (RTK) GPS and individual, high-resolution, oriented photographs of subsurface pits. Lithologic mapping information of the Kidd Copper tailings deposit can provide an insight into the distribution of local aquifers and aquitards. Subsurface lithologic mapping was achieved using a combination of sub-centimetre-resolution RTK GPS and individual, high-resolution, oriented photographs of subsurface pits. The photograph of each pit provides lithologic information of a specific point in the tailings deposit, while the high-resolution GPS locates the individual photographs in three-dimensional (3D) geographic space. Combining these data allows us to identify continuous lithologic surfaces between pits, leading to the construction of a 3D model of the deposition of the tailings pond. Grain size and textural details extracted from the images of each lithology permit discrimination between aquifers and aquitards. The final geometric model could be used as input for estimating the hydrologic and chemical evolution of the tailings.     

Interpersonal subtypes and change of interpersonal problems in the treatment of patients with generalized anxiety disorder: A pilot study.

Interpersonal problems are highly relevant to the treatment of generalized anxiety disorder (GAD) patients. Previous studies using the Inventory of Interpersonal Problems identified several interpersonal subtypes in GAD patients. In this study, we wanted to replicate earlier findings of interpersonal subtypes in GAD. We investigated whether these interpersonal subtypes are characterized by different types of interpersonal problems and different levels of interpersonal distress, and we further examined whether they differed with regard to improvement of interpersonal problems after short-term treatment. This study is based on results from a randomized controlled trial that investigated short-term treatments in GAD outpatients. For secondary analysis, interpersonal subtypes were identified by cluster analysis and Inventory of Interpersonal Problems profiles were calculated for both the total sample (N = 52) and the interpersonal subtypes using the Structural Summary Method for Circumplex Data. This study confirmed previous results demonstrating the existence of interpersonal subtypes in GAD. Four interpersonal subtypes were identified: Overly Nurturant, Intrusive, Socially Avoidant, and Nonassertive. Short-term treatment significantly improved interpersonal problems (d = 0.46) within the total GAD sample. Interestingly, the effect sizes of the four clusters differed considerably (d = 0.19–1.24) and the clusters displayed different changes in the two circumplex axes Dominance and Nurturance. Our study indicates that change of interpersonal problems needs to be specifically analyzed, even within homogenous diagnostic groups.

Integration of Low-Impact Development into the International Stormwater BMP Database

Low impact development (LID) strategies are being encouraged in many communities as an approach to reduce potential adverse impacts of development on receiving streams. Many questions exist regarding how well various LID strategies perform in different settings, just as similar questions have been raised regarding performance of traditional stormwater best management practices (BMPs). Whereas historical focus on BMP performance has been water quality concentrations or loads, characterization of volume reduction benefits for both conventional and LID practices is increasingly an objective of researchers and stormwater managers. More than a decade ago, Urban Water Resources Research Council (UWRRC) members worked to develop a set of standardized monitoring and reporting protocols for traditional BMPs and to establish a master database for the purpose of evaluating BMP performance and the factors affecting performance. This effort culminated in the International Stormwater BMP Database (www.bmpdatabase.org), which contains data for more than 360 BMPs and continues to operate as a clearinghouse for stormwater BMP data and performance analyses. During 2008–2009, the International Stormwater BMP Database project expanded to better integrate LID into the database and develop a set of metrics that can be used to characterize BMP performance with regard to surface runoff volume reduction. This paper provides a condensed overview and progress report on the LID-focused effort, including the following topics: (1)?monitoring guidance for LID at the overall site development level, (2)?an overview of recent changes to the International Stormwater BMP Database to better accommodate LID studies, (3)?a summary of LID studies currently included in the database, and (4)?a proposed approach for evaluating performance of LID studies with regard to reducing surface runoff volumes.     

Effects of multisystemic therapy through midlife: A 21.9-year follow-up to a randomized clinical trial with serious and violent juvenile offenders.

Objective: Although current evidence suggests that the positive effects of multisystemic therapy (MST) on serious crime reach as far as young adulthood, the longer term impact of MST on criminal and noncriminal outcomes in midlife has not been evaluated. In the present study, the authors examined a broad range of criminal and civil court outcomes for serious and violent juvenile offenders who participated on average 21.9 (range = 18.3–23.8) years earlier in a clinical trial of MST (C. M. Borduin et al., 1995). Method: Participants were 176 individuals who were originally randomized to MST or individual therapy (IT) during adolescence and averaged 3.9 arrests for felonies prior to treatment. Arrest, incarceration, and civil suit data were obtained in middle adulthood when participants were on average 37.3 years old. Results: Intent-to-treat analyses showed that felony recidivism rates were significantly lower for MST participants than for IT participants (34.8% vs. 54.8%, respectively) and that the frequency of misdemeanor offending was 5.0 times lower for MST participants. In addition, the odds of involvement in family-related civil suits during adulthood were twice as high for IT participants as for MST participants. Conclusions: The present study represents the longest follow-up to date of an MST clinical trial and demonstrates that the positive impact of an evidence-based youth treatment such as MST can last well into adulthood. Implications of the authors' findings for policymakers and service providers are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Reflections on the virtues of modularity: a case study in linux security modules

Developing a modular system that properly supports a range of security models is challenging. The work presented here details our experiences with the modular Linux security framework called Linux Security Modules, or LSMs. Throughout our experiences we discovered that the developers of the LSM framework made certain tradeoffs for speed and simplicity during implementation, and consequently leaving the framework incomplete. Our experiences show at which points the theory of the LSM differs from reality, and details how these differences play out when developing and using a custom LSM.

Evaluating model fit for growth curve models: Integration of fit indices from SEM and MLM frameworks.

Evaluating overall model fit for growth curve models involves 3 challenging issues. (a) Three types of longitudinal data with different implications for model fit may be distinguished: balanced on time with complete data, balanced on time with data missing at random, and unbalanced on time. (b) Traditional work on fit from the structural equation modeling (SEM) perspective has focused only on the covariance structure, but growth curve models have four potential sources of misspecification: within-individual covariance matrix, between-individuals covariance matrix, marginal mean structure, and conditional mean structure. (c) Growth curve models can be estimated in both the SEM and multilevel modeling (MLM) frameworks; these have different emphases for the evaluation of model fit. In this article, the authors discuss the challenges presented by these 3 issues in the calculation and interpretation of SEM- and MLM-based fit indices for growth curve models and conclude by identifying some lines for future research.

Elastomeric Electronic Skin for Prosthetic Tactile Sensation

This report demonstrates a wearable elastomer‐based electronic skin including resistive sensors for monitoring finger articulation and capacitive tactile pressure sensors that register distributed pressure along the entire length of the finger. Pressure sensitivity in the order of 0.001 to 0.01 kPa^?1 for pressures from 5 to 405 kPa, which includes much of the range of human physiological sensing, is achieved by implementing soft, compressible silicone foam as the dielectric and stretchable thin‐metal films. Integrating these sensors in a textile glove allows the decoupling of the strain and pressure cross‐sensitivity of the tactile sensors, enabling precise grasp analysis. The sensorized glove is implemented in a human‐in‐the‐loop system for controlling the grasp of objects, a critical step toward hand prosthesis with integrated sensing capabilities.     

Transformations for early reply and forward message passing mechanisms

Message passing notations (language, package, etc.) typically include some form of asynchronous or synchronous invocation. In a synchronous invocation, the invoker waits for the invocation's servicer to pass back results. Some message passing notations also include early reply or deferred reply (including forwarding), which alters how and when the servicer passes back its results; this additional flexibility is useful in realistic applications. It is well known how to transform a synchronous invocation into only asynchronous invocations. This paper extends such transformations to early reply and forward. This paper also describes the use of these transformations within the implementations of programming notations. Using the transformation simplifies the implementation without significantly affecting run‐time costs. Copyright © 2015 John Wiley & Sons, Ltd.
