Memory Monitoring

Many monitoring tools that help developers in analyzing the run-time behavior of their applications share a common shortcoming: they require their users to have a fair amount of experience in monitoring applications to understand the used terminology and the available analysis features. Consequently, novice users who lack this knowledge often struggle to use these tools efficiently. In this paper, we introduce the guided exploration (GE) method that aims to make interactive monitoring tools easier to use and learn. In general, tools that implement GE should provide four support operations on each analysis step: they should automatically (1) detect and (2) highlight the most important information on the screen, (3) explain why it is important, and (4) suggest which next steps are appropriate. This way, tools guide users through their analysis processes, helping them to explore the root cause of a problem. At the same time, users learn the capabilities of the tool and how to use them efficiently. We show how GE can be implemented in new monitoring tools as well as how it can be integrated into existing ones. To demonstrate GE's feasibility and usefulness, we present how we extended the memory monitoring tool AntTracks to provided guided exploration support during memory leak analysis and memory churn analysis. We use these guidances in two user scenarios to inspect and improve the memory behavior of the monitored applications. We hope that our contribution will help usability researchers and developers in making monitoring tools more novice-friendly by improving their usability and learnability.

Supply Interruptions

Drought is a natural disaster that influences many aspects of society. Since the demand for water is increasing along with the population in many parts of the world, water supply interruptions caused by drought can be expected to produce greater impacts. This is because the impacts of drought are determined not only by the frequency and intensity of meteorological drought but also by the number of people at risk and their degree of risk (Wilhite, 2000). For example, the increase in population in Africa and Asia increases drought vulnerability significantly. Thus, policies that promote the development and implementation of appropriate drought mitigation measures today will help to reduce the economic, social, and environmental impacts associated with future droughts and the need for government intervention. To monitor drought, different types of indicators (e.g., drought indices) have been used in many parts of the world. Because there is no single definition for drought, determining which indicators to use poses more difficulties for planners. Decision makers use different policies and strategies based on the historical records of their countries. For example, in Australia, when meteorological drought (annual rainfalls in the lowest 10% of recorded values) occurred over at least 10% of the continent, it coincided with damaging agricultural droughts resulting significant losses of crops and livestock (Heathcote, 2000). Because of the varied and potentially catastrophic losses resulting from drought in many parts of the world, both governmental and non-governmental decision makers need better predictive and monitoring tools to assist them in dealing more effectively with drought. Better early warning and prediction is the foundation of a new drought management paradigm based on risk management. In South Africa, the Weather Bureau issues extended outlooks for short and long periods using numerical modeling and statistical methods (Vogel, Lang, & Monnik, 2000). In United States, recent advances in science and technology are enhancing drought monitoring capabilities and the availability of such information, which allows decision makers to make more knowledge-based decisions to lessen the impacts of drought. In this article, we highlight the role of government in drought planning and mitigation, the potential of data mining techniques and their outputs (e.g., maps and tables) for improving informed decision making, and also present a newly developed drought monitoring tool, the Vegetation Drought Response Index (VegDRI) as an example over the central United States.

Disease Activity Assessment

Abstract Background Management of inflammatory bowel disease (IBD) is directed toward both clinical symptoms as well as objective disease activity as a part of a ‘treat to target’ strategy. Despite the increasing burden of disease activity assessment in IBD, patient preferences for monitoring tools have scarcely been considered. This study aimed to describe the available evidence for patient preference, satisfaction, tolerance and/or acceptability of the available monitoring tools in adults with IBD. Methods A systematic search of Embase, Medline, Pubmed, Cochrane Central and Clinical Trials.gov from January 1980 to April 2019 was conducted using PRISMA best practice guidelines. Included were all study types reporting on the perspectives of adults with confirmed IBD on monitoring tools, where two or more such tools were compared. Outcome measures with summary and descriptive data were presented. Results 10 studies evaluating 1846 participants were included. Study size ranged from 18 to 916 participants. Monitoring tools included venepuncture, stool collection and faecal calprotectin (FC), gastrointestinal ultrasound (GIUS), computed tomography (CT), magnetic resonance imaging (MRI), wireless capsule endoscopy (WCE), barium follow-through, and endoscopy. The measurement tools used were visual analogue scales (VAS), Likert scales or binary preference questions. Outcome domains were patient satisfaction, acceptability of monitoring tool, and patient preference. Meta-analysis was not possible due to heterogeneity of data. Overall, patient preference was for non-invasive tools of disease monitoring and these were associated with a higher level of acceptability. Across all included studies, GIUS was identified by patients as the preferred tool for disease activity assessment. Both FC and other forms of imaging (MRE and CTE) were generally considered preferable to endoscopy, however less so than GIUS. Patient preference for blood testing varied, but in one study was lower than endoscopy. Two studies compared VAS acceptability of multiple IBD monitoring tools. Among 1037 patients, GIUS was considered the most acceptable IBD monitoring tool (mean VAS 9.29), as compared with venepuncture (9.28), WCE (8.5), MRE (8.08), stool collection (7.87), colonoscopy (7.07) and sigmoidoscopy (5.27). Conclusion This is the first systematic review to evaluate patient perceptions of monitoring tools used in IBD. Patients showed a preference for GIUS and more generally for faecal sampling and non-invasive imaging over endoscopy. Further research should address whether clinician selection of more acceptable monitoring tools in IBD engenders greater patient satisfaction, adherence, and a consequent improvement in disease-related outcomes.

Social Observation

This study capitalizes on a successful researcher–practitioner partnership to conduct a systematic social observation (SSO) of police body-worn camera (BWC) footage in Newark, NJ. To demonstrate the utility of BWCs as performance monitoring tools, we measure officer adherence to procedural justice standards throughout use of force events as mandated in the Newark Police Division’s updated policies pursuant to an ongoing federal consent decree. Overall, a slim majority of use of force events are procedurally just. However, results indicate several instances of policy noncompliance. Results are discussed, and policy recommendations related to procedural justice policy violations and BWCs for performance monitoring are provided.

Abstract Objectives Adherence to diet self-monitoring tools typically declines over time. Diet self-monitoring tools often ask people to itemize their foods and record their serving sizes. This method of tracking does not conform to food guides that resemble a plate. The objective of this study is to explore the perceptions of healthy older adults on the usability of a traditional food journal (Journal) compared to a simplified plate-based (Plate) tool based on the 2019 Canada's Food Guide. Methods A crossover study design was used to evaluate the two tools. Participants (n = 48) were randomized to track their food on three days using either the Journal or the Plate for one week then the other tool for the following week. Once complete, 45 participants completed semi-structured interviews to assess their perceptions of the tools and their preferences. Results were analyzed using thematic analysis to identify emerging themes. Results The main themes identified for the Plate were “easy”, “visual”, and “quick” whereas for the Journal were “detail”, “quantification”, and “familiarity”, with 46.7% and 46.7% preferring the Plate and Journal respectively (6.7% preferred neither tool). When asked about using the tools for future dietary changes, 62.2% and 31.1% preferred the Plate and Journal respectively (6.7% preferred neither tool). Conclusions A simplified tool such as a plate is an acceptable self-monitoring tool for older adults. Future studies will be test adherence to self-monitoring using this simplified plate based self-monitoring tool. Funding Sources R. Howard Webster Foundation

New Infrastructure

For the last 10 years, the ATLAS Distributed Computing project has based its monitoring infrastructure on a set of custom designed dashboards provided by CERN. This system functioned very well for LHC Runs 1 and 2, but its maintenance has progressively become more difficult and the conditions for Run 3, starting in 2021, will be even more demanding; hence a more standard code base and more automatic operations are needed. A new infrastructure has been provided by CERN, based on InfluxDB as the data store and Grafana as the display environment. ATLAS has adapted and further developed its monitoring tools to use this infrastructure for data and workflow management monitoring and accounting dashboards, expanding the range of previous possibilities with the aim to achieve a single, simpler, environment for all monitoring applications. This document describes these tools and the data flows for monitoring and accounting.

Insight Into

From 2008 to 2018, South Africa permitted the export of captive-bred African lion (Panthera leo) skeletons to Southeast Asia under CITES Appendix II. Legal exports rose from approximately 50 individuals in 2008 to a maximum of 1,771 skeletons in 2016, and has led to ongoing concerns over possible laundering of non-lion, multiple-source and wild-sourced bones. South Africa is required under its obligations to CITES to employ mechanisms for monitoring and reporting trade, and to limit the potential for illegal trade and laundering of lion and other large felid bones. Monitoring tools for legal trade are critical to compliance with CITES. Here we evaluate the CITES-compliance procedure implemented by South Africa for export of lion bones and identify six essential general points for consideration in the implementation of animal export quota compliance protocols. We provide specific insight into the South African lion bone export monitoring system through: i) outlining the protocols followed; ii) assessing the utility of cranial morphology to identify species; iii) evaluating skeleton consignment weight as a monitoring tool; and iv) presenting molecular (DNA) species assignment and pairwise-comparative sample matching of individuals. We describe irregularities and illicit behaviour detected in the 2017 and 2018 lion bone quotas. Notably, we report that the compliance procedure successfully identified and prevented the attempted laundering of a tiger (P. tigris) skeleton in 2018. We emphasise the utility of mixed-method protocols for the monitoring of compliance in CITES Appendix II export quota systems.
