"All-fiber" tunable laser in the 2 mu m region, designed for CO2 detection

A stable and tunable thulium-doped “all-fiber” laser offering a narrow linewidth has been created specifically to act as a compact and simple laser source for gaseous CO2 detection. This has been done through a careful design to match the laser output wavelengths to the CO2 absorption lines at 1.875 and 1.997 μm, respectively. A sustainable output power of 11 mW over a tuning range of 7 nm has been obtained by using a combination of a high-reflective fiber Bragg grating with a low-reflective broadband mirror, fabricated at the end of the fiber through silver film deposition. The tuning was achieved using the relaxation-compression mechanism of the fiber Bragg grating, which formed an integral part of the laser resonant cavity. A fiber Bragg grating at 1.548 μm was utilized as a wavelength reference to monitor the tuning of the laser output over the 2 μm wavelength range with a simple and inexpensive interrogator, to avoid the use of an expensive optical spectrum analyzer and to facilitate “in-the-field” operation. This “all-fiber” laser resonator has been shown to be superior in terms of laser tuning range, output power, and linewidth compared to that created with a fiber Bragg grating pair, which was limited by the nonuniform strain transfer to both fiber Bragg gratings

Spendthrift Trust: An Alternative to the NBA Age Rule

(Excerpt) This Note argues that the NBA Age Rule has created a problem for which a legal solution exists: the adoption of a spendthrift trust system. The NBA Age Rule fails to achieve the NBA\u27s goal of protecting amateur players. Instead, it merely limits potential and growth for both the NBA and aspiring players. Part I details the history and rationale behind the NBA Age Rule. Part II analyzes the inefficiency of the NBA Age Rule and demonstrates how the NBA Age Rule unfairly denies amateur players the opportunity to play in the NBA. Part III outlines a spendthrift trust system that would permit high school players to enter the NBA Draft directly out of high school and would alleviate the NBA\u27s policy concerns

What can clinicians do to improve outcomes across psychiatric treatments: a conceptual review of non-specific components.

AIMS: Psychiatric treatments have specific and non-specific components. The latter has been addressed in an extensive literature on the placebo-effect in pharmacology and on common factors in psychotherapy. In the practice of mental health care, pharmacological, psychotherapeutic and social treatments are combined in complex interventions. This paper aims to review non-specific components across diverse psychiatric treatments and consider implications for practice and research. METHODS: We conducted a non-systematic review of non-specific components across psychiatric treatments, their impact on treatment processes and outcomes, and interventions to improve them. RESULTS: The identified research is heterogeneous, both in design and quality. All non-specific components capture aspects of how clinicians communicate with patients. They are grouped into general verbal communication - focusing on initial contacts, empathy, clarity of communication, and detecting cues about unspoken concerns - non-verbal communication, the framing of treatments and decision-making. The evidence is stronger for the impact of these components on process measures - i.e. therapeutic relationship, treatment satisfaction and adherence than on clinical outcomes - i.e. symptoms and relapse. A small number of trials suggest that brief training courses and simple methods for structuring parts of clinical consultations can improve communication and subsequently clinical outcomes. CONCLUSIONS: Methodologically, rigorous research advancing current understandings of non-specific components may increase effectiveness across different treatments, potentially benefitting large numbers of patients. Brief training for clinicians and structuring clinical communication should be used more widely in practice

Revitalising the JRC Strategy 2030

The JRC Strategy 2030, adopted in 2016, reinforced the JRC’s position as the science for policy Directorate-General of the European Commission. This document is a complement to, and an evolution of, that strategy, seeking to reset, re-imagine and re-energise the JRC, signalling an increased openness to engaging with partners to put science at the service of the European project.JRC.01 - Communicatio

Continuous quality improvement in measure development: Lessons from building a novel clinical feedback system

Purpose While the use of clinical feedback systems has become commonplace in psychological treatment, many of the most common instruments used for this purpose have not changed in decades. This paper describes the first four cycles of a measure development method designed to embrace continuous quality improvement. Methods Using techniques and philosophies developed in business management and academia—lean continuous quality improvement, action research, and practice research networks—we iterated through multiple cycles of development with the goal of creating an optimal clinical feedback system. These cycles emphasize building capacity to receive and implement feedback from a variety of stakeholders, especially patients and providers of behavioral health services, while also being responsive to quantitative findings from measure development. Results Iterating measure development with stakeholder feedback over the course of 5 years has resulted in a novel measurement system with 19 subscales administered via branching logic, and a supporting practice research network to sustain development. Conclusion In developing a new clinical feedback system, the less-frequently-discussed practical aspects of measure development require close attention. Specifically, being willing to embrace change, planning for iteration, and systematically seeking stakeholder feedback are identified as central methods for improving clinical feedback systems.publishedVersio

Initial quantitative development of the Norse Feedback system: a novel clinical feedback system for routine mental healthcare

Purpose As routine outcome monitoring has become prevalent in psychological practice, there is need for measurement tools covering diverse symptoms, treatment processes, patient strengths, and risks. Here we describe the development and initial tests of the psychometric properties of a multi-scale system for use in mental healthcare, Norse Feedback. Methods In Study 1, we present the item-generation process and structure of the Norse Feedback, a 17-scale digital-first measurement tool for psychopathology and treatment-relevant variables. In Study 2, we present analyses of this initial measure in a nonclinical sample of 794 healthy controls and a sample of 222 mental health patients. In Study 3, we present the analysis of a revised 20-scale system in two separate samples of patients. In each analysis, we investigate item and test information in particular, including analysis of differential item functioning on gender, age, site, and sample differences where applicable. Results Scales performed variably. Changes to items and scales are described. Several scales appeared to reliably discriminate individuals entering mental health treatment on severity, and others are less reliable. Marked improvements in scale internal consistency and measurement precision were observed between the first and second implemented versions. Conclusion This system includes some scales with reasonable structural validity, though several areas for future development are identified. The system was developed to be iteratively re-evaluated, to strengthen the validity of its scales over time. There are currently a number of limitations on inferences from these scores, which future developments should address.publishedVersio
