Presentation Title: Exploring The Evidence: A Systematic Review Of Smart Recovery Evaluations
Contributors: Alison K. Beck, Amanda L. Baker, Peter J. Kelly, Anthony Shakeshaft, Frank P. Deane, David Hunt
Presenter: Alison Beck
Introduction and Aims: Self-help groups are integral to the process of addiction recovery. Self-Management and Recovery Training (SMART Recovery) was borne from a need for an alternative to 12 step approaches. SMART Recovery adopts key principles (e.g. self-efficacy) and therapeutic approaches (e.g. motivational interviewing and cognitive behavioural therapy) shown to be effective in promoting recovery from addiction. However, further clarity regarding SMART Recovery as a mutual-aid support package is needed. This systematic review will provide an overview of the current state of evidence for SMART Recovery including outcomes, potential mediators and a critical evaluation of the methods used to evaluate SMART Recovery.
Design and Methods: Six electronic peer-reviewed and four grey literature databases were searched for literature on SMART Recovery. Articles classified as ‘evaluation’ were assessed against standardised criteria.
Results: Preliminary searches identified nine evaluations of SMART Recovery, including one randomised controlled trial which found clinically significant improvements in alcohol use following SMART Recovery. Although positive findings were apparent, the remaining evaluations were largely cross-sectional, focused on process relative to outcome measures and/or evaluated SMART Recovery within a specific treatment context (e.g. dual diagnosis).
Discussion and Conclusions: The SMART Recovery model is grounded in science. Evidence from one ‘gold standard’ evaluation supports the role of both face-to-face and web versions in promoting recovery from alcohol addiction. Further high quality evaluations are needed to understand the impact on other addictive behaviours and possible mechanisms of action.
Implications for Practice or Policy: Campaigning for change in healthcare practice and policy relies on a solid evidence base. This systematic review represents an important step in generating the evidence needed to refine, disseminate and raise the profile of SMART Recovery as an effective alternative to traditional 12 step approaches for long-term addiction recovery support.
The Australasian Professional Society on Alcohol and other Drugs (APSAD) held it’s 35th conference in Perth for the 2015 APSAD Scientific Alcohol and Drug Conference.
What is SMART Recovery?
SMART (Self Management and Recovery Training) Recovery is a free group program assisting any problematic behaviours, including addiction to drugs, alcohol, cigarettes, gambling, food, shopping, Internet and others. Guided by trained peers and professionals, participants come to help themselves and help each other using a variety of cognitive behaviour therapy (CBT) and motivational tools and techniques.
The document discusses the history and characteristics of prehistoric art from the Paleolithic, Mesolithic, and Neolithic periods. During the Paleolithic period, which lasted from around 2 million years ago to 13,000 BC, humans lived nomadic lifestyles and created cave paintings and sculptures. Art reached its peak during this period. In the Mesolithic and Neolithic periods, which followed, humans began domesticating plants and animals, forming settled communities, and developing pottery and architecture. Neolithic art depicted more human figures and was used more for ornamentation and in fixed locations like temples.
Umberger Telehospice Literature Review ProposalPaul Umby
This proposal outlines a systematic review of the literature on telehospice. Telehospice uses telemedicine technology to provide home hospice care and has the potential to increase access to hospice services for rural and underserved communities. The review aims to identify how telehospice is currently being used and who is utilizing these services. It will use the PRISMA guidelines to search, review, and analyze relevant literature on telehospice in order to better understand the state of telehospice and inform discussions on increasing access to end-of-life care.
Improve Patient Engagement with Five Public Health-Inspired PrinciplesHealth Catalyst
Patient engagement is critical as we move toward population health—as patients who engage in their own care by following medical recommendations and making healthy nutrition and lifestyle choices will have better outcomes and experiences.
There isn’t, however, a clear path to successful patient engagement. Fortunately, public health can lend several established principles that may help us better involve patients in their own care:
Using systematic, population-level solutions that require less individual effort.
Engaging patients on interpersonal and community levels as well as personal.
Identifying root-cause, assessing and capitalizing on strengths, and engaging stakeholders.
Using strategies from behavioral economics to help individuals make good choices.
Anticipating failure and learning from it.
Systematic Reviews: the process, quantitative, qualitative and mixed methods ...healthlibaust2012
This document discusses systematic reviews and their process. It defines systematic reviews as attempts to identify, appraise, and synthesize all empirical evidence that meets pre-specified eligibility criteria to answer a given research question. It notes there are quantitative, qualitative, and mixed methods reviews. The document outlines the steps in conducting a systematic review, including developing a protocol and research question, locating studies, assessing studies, extracting and analyzing data, and presenting results.
This document discusses patient flow management in an outpatient department. It aims to understand problems patients face such as long wait times, identify bottlenecks causing delays, and recommend solutions. Data was collected through observation of 300 random patients to record wait times at various stages. On average, patients waited longest for doctor consultation at 37.1 minutes and report dispatch at 63.1 minutes. The analysis found the main bottlenecks were improper scheduling of doctors and radiologists, leading to delayed report dispatch. Solutions are suggested to improve patient care delivery and optimize patient flow.

It presents the results of a systematic literature review of 44 studies on machine learning technique usage from 2010 to 2014. The review aimed to identify the most common machine learning techniques, their applications, appropriate data types, and strengths and weaknesses. The techniques most frequently used were found to be support vector machines, artificial neural networks, naive Bayes, decision trees, and k-nearest neighbors. The studies covered fields such as medicine, pharmacology, agriculture, archaeology, games, and business.
Urban Car Parks as Fashion Event Venue: A Reflection Study of London Fashion ...Peachy Essay
The research methodology in a study majorly defines key methods to carry out an investigation in the desired field (Pérez, 2009). In other words, it informs readers that how the research is proceeded using the wealth of human knowledge (developed by researchers critically) as well as different tools to look at life objectively). Commendably, research methodology is considered a way to systematically resolve different research problems with the help of logically adopted steps (Creswell, 2013). Thereof, this chapter has been devised for the current study that relies on specific research problem regarding the performance of different venues on fashion event management by analysing the case of London Fashion Week 2016 in London Brewer Street Car Park. In this chapter, some specific aspects have been discussed including the area of study, research design, research philosophy, approach, methods or instrument for data collection and analysis, and ethical concerns. To organise this chapter, Honeycomb Model (2012) and Onion Research Model (2014) of methodology have been followed that help in providing a structure to the methods along with various available options/alternatives and selection criteria supported by justification.

Collaborative model driven software engineering: a Systematic Mapping StudyDavide Ruscio
Collaborative software engineering (CoSE) deals with methods, processes and tools for enhancing collaboration, communication, and co-ordination (3C) among team members. CoSE can be employed to conceive different kinds of artifacts during the development and evolution of software systems. For instance, when focusing on software design, multiple stakeholders with different expertise and responsibility collaborate on the system design.
Model-Driven Software Engineering (MDSE) provides suitable techniques and tools for specifying, manipulating, and analyzing modeling artifacts including metamodels, models, and transformations. A collaborative MDSE approach can be defined as a method or technique allowing multiple stakeholders to work on a set of shared modeling artifacts, and to be aware of each others’ work. Even though Collaborative MDSE is gaining a growing interest in both academia and practice, a holistic view on what Collaborative MDSE is, its components, the related opportunities and challenges is still missing.
In this talk, I outlined the main insights of the systematic mapping study we have done to identify and classify approaches, methods, and techniques that support collaborative. We present three complementary dimensions that we have identified during the study as the peculiar aspects building up a collaborative MDSE: a model management infrastructure for managing the life cycle of the models, a set of collaboration means for allowing involved stakeholders to work on the modelling artifacts collaboratively, and a set of communication means for allowing involved stakeholders to be aware of the activities of the other stakeholders. The identification of limitations and challenges of currently available collaborative MDE approaches is also given by discussing the implications for future investigation.

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...Paul Brebner
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

Main findings
2
We found a low number of papers involving UML
This may be because UML notations have specific
forums for publication
40. 40 April 6, 2016
Main findings
3
There is a dominance of more generic usability
attributes (e.g., understandability and usability)
The main results are typically about the key
advantages of the approach and open research
challenges
41. 41 April 6, 2016
Main findings
Only a minority of the studies use a control group
to compare the approach with some baseline
There is a positive tendency to make available the
raw data of the analysis
