Multilinguals and Wikipedia Editing

This article analyzes one month of edits to Wikipedia in order to examine the role of users editing multiple language editions (referred to as multilingual users). Such multilingual users may serve an important function in diffusing information across different language editions of the encyclopedia, and prior work has suggested this could reduce the level of self-focus bias in each edition. This study finds multilingual users are much more active than their single-edition (monolingual) counterparts. They are found in all language editions, but smaller-sized editions with fewer users have a higher percentage of multilingual users than larger-sized editions. About a quarter of multilingual users always edit the same articles in multiple languages, while just over 40% of multilingual users edit different articles in different languages. When non-English users do edit a second language edition, that edition is most frequently English. Nonetheless, several regional and linguistic cross-editing patterns are also present

Engaging persons with mental illness and/or substance use disorder in care coordination services: an improvement project at a federally qualified community health center

Background: Mental health and substance use disorders seldom occur in isolation. They frequently accompany each other, as well as a substantial number of chronic general medical illnesses. Consequently, mental health conditions, substance-use disorders, and general health conditions are frequently co-occurring, and coordination of all of these types of health care is essential to improved health outcomes (Institute of Medicine, 2006). The U.S. system of healthcare is failing to identify, engage, and effectively treat people who are suffering from behavioral health conditions (Blanco, Coye, Knickman, Krishnan, Krystal, Pincus, Rauch, Simon, Vitiello, 2016). Because of poor coordination and lack of engagement, people often experience disrupted care and an over-reliance on emergency department and hospital care. At Lowell Community Health Center where this project takes place persons with a primary behavioral health diagnosis contribute to the highest utilization of emergency and inpatient hospital services. In July of 2018, Lowell CHC collaborated with Lowell House, Inc. to form a care coordination program to outreach and engage individuals identified as high utilizers of inpatient and emergency hospital services. Aim: The aim of this project is to describe the attributes of the population of patients who successfully engaged into care for the first six months of this new program, with recommendations for improvement to inform future program design. Method: The population of patients who successfully engaged in care in the first 6 months of the program described by independent variables consisting of age, gender, race, and preferred language. Dependent variable consisting of type of outreach. Data was evaluated to determine attributes of patients who successfully engaged in care and if correlations exist between variables and successful engagement. Results: The first six months of the program implementation demonstrated successful engagement and activation of 17.5% of patients. The average patient is described as low-income, 50-64 years of age, non-English speaking female with dual-diagnosis residing in the greater Lowell area. Themes regarding successful outreach type included telephonic and face-to-face being the most successful method of engagement. Although successful engagement was noted, longer-term efforts and analysis should focus on successful outreach and engagement strategies, emergency room utilization, treatment adherence and service adherence. Conclusions: The findings of this project indicate that having a team-based, multidisciplinary and multi-cultural approach to care coordination has led to successful engagement of 186 individuals within the first 6 months of this new program

Solar energy modulator

A module is described with a receiver having a solar energy acceptance opening and supported by a mounting ring along the optic axis of a parabolic mirror in coaxial alignment for receiving solar energy from the mirror, and a solar flux modulator plate for varying the quantity of solar energy flux received by the acceptance opening of the module. The modulator plate is characterized by an annular, plate-like body, the internal diameter of which is equal to or slightly greater than the diameter of the solar energy acceptance opening of the receiver. Slave cylinders are connected to the modulator plate for supporting the plate for axial displacement along the axis of the mirror, therby shading the opening with respect to solar energy flux reflected from the surface of the mirror to the solar energy acceptance opening

Gamma-ray Burst Positions from the ASM on RXTE

The RXTE/ASM has detected and positioned 14 confirmed GRB bursts (at this writing, Jan. 1999) including six whose positions were comunicated to the community 2 to 32 hours after the burst. Two of these latter bursts led to measurements of optical red shifts but one, despite an easily detected x-ray afterglow, produced no detectable optical or radio afterglow.Comment: 2 pages, 1 Figure, A&A format, accepted to appear in the proceedings of the conference "Gamma-Ray Bursts in the Afterglow Era", Rome, 3-6 Nov, 199

The environmental externalities of tobacco manufacturing: A review of tobacco industry reporting.

Growing research and public awareness of the environmental impacts of tobacco present an opportunity for environmental science and public health to work together. Various United Nations agencies share interests in mitigating the environmental costs of tobacco. Since 2000, transnational tobacco industry consolidation has accelerated, spotlighting the specific companies responsible for the environmental and human harms along the tobacco production chain. Simultaneously, corporate social responsibility norms have led the industry to disclose statistics on the environmental harms their business causes. Yet, independent and consistent reporting remain hurdles to accurately assessing tobacco's environmental impact. This article is the first to analyze publicly available industry data on tobacco manufacturing pollution. Tobacco's significant environmental impact suggests this industry should be included in environmental analyses as a driver of environmental degradation influencing climate change. Countries aiming to meet UN Sustainable Development Goals must act to reduce environmental harms caused by the tobacco industry

Modeling the Rise in Internet-based Petitions

Contemporary collective action, much of which involves social media and other Internet-based platforms, leaves a digital imprint which may be harvested to better understand the dynamics of mobilization. Petition signing is an example of collective action which has gained in popularity with rising use of social media and provides such data for the whole population of petition signatories for a given platform. This paper tracks the growth curves of all 20,000 petitions to the UK government over 18 months, analyzing the rate of growth and outreach mechanism. Previous research has suggested the importance of the first day to the ultimate success of a petition, but has not examined early growth within that day, made possible here through hourly resolution in the data. The analysis shows that the vast majority of petitions do not achieve any measure of success; over 99 percent fail to get the 10,000 signatures required for an official response and only 0.1 percent attain the 100,000 required for a parliamentary debate. We analyze the data through a multiplicative process model framework to explain the heterogeneous growth of signatures at the population level. We define and measure an average outreach factor for petitions and show that it decays very fast (reducing to 0.1% after 10 hours). After 24 hours, a petition's fate is virtually set. The findings seem to challenge conventional analyses of collective action from economics and political science, where the production function has been assumed to follow an S-shaped curve.Comment: Submitted to EPJ Data Scienc

A Rayleigh-Ritz approach to the synthesis of large structures with rotating flexible components

The equations of motion for large structures with rotating flexible components are derived by regarding the structure as an assemblage of substructures. Based on a stationarity principle for rotating structures, it is shown that each continuous or discrete substructure can be simulated by a suitable set of admissible functions or admissible vectors. This substructure synthesis approach provides a rational basis for truncating the number of degrees of freedom both of each substructure and of the assembled structure

Dynamic analysis of the long-term zonal earth energy budget experiment (LZEEBE) spacecraft

The motions of the flexible LZEEBE spacecraft after injection into a circular orbit were analyzed. The spacecraft consists of three spherical balloons connected to a central hub by three long flexible booms which lie in a plane such that the angle between any pair of booms is 120 degrees. The major torques acting on the spacecraft are gravity-gradient torques and torques due to solar radiation pressure acting on the balloons which have different reflective properties. A development of the equations of motion is presented. Computer simulations indicate that the spacecraft will have random motion, provided the injection into orbit does not create conditions favorable to gravity-gradient capture

Structural Dynamics, Stability, and Control of Helicopters

The dynamic synthesis of gyroscopic structures consisting of point-connected substructures is investigated. The objective is to develop a mathematical model capable of an adequate simulation of the modal characteristics of a helicopter using a minimum number of degrees of freedom. The basic approach is to regard the helicopter structure as an assemblage of flexible substructures. The variational equations for the perturbed motion about certain equilibrium solutions are derived. The discretized variational equations can be conveniently exhibited in matrix form, and a great deal of information about the system modal characteristics can be extracted from the coefficient matrices. The derivation of the variational equations requires a monumental amount of algebraic operations. To automate this task a symbolic manipulation program on a digital computer is developed
