This article presents the system Seek&Hide, a text message processing tool developed for the sud4science LR (http://www.sud4science.org/) project. It performs the anonymisation/de-identification of a corpus. At present, it has been used to anonymise the sud4science LR corpus of French text messages collected during the project. This is done in two phases. In the first phase, it automatically processes over 70% of the corpus. The rest of the corpus is processed in the second phase, aided by an expert annotator via a web interface specifically designed to simplify the task.

The literature suggests that volunteering can be used to address social isolation and support patients with psychosis in the community. However, many expect in person meetings, requiring a greater effort of availability and commitment. There is therefore a need for more flexible, easily accessible support. Volunteering via smart-phone could be a useful intervention for people with psychosis. One patient and one volunteer have been matched for a duration of 12 weeks, and participants have been encouraged to communicate through a variety of communication methods (audio calls, video calls, text messages, WhatsApp messages and e-mails). The Phone Pal study aimed to investigate the feasibility of recruitment, participant retention, data collection procedures, intervention usage of the methods of communication and changes in outcome data. At baseline and follow-up outcome measures collected from patients and volunteers included their quality of life, physical activity, self-esteem and social comparison. Additional outcomes assessed patients' attachment, social contacts and symptoms; for volunteers, their social distance was evaluated. At follow-up both patients and volunteers rank their perception of their relationship with each other. This mixed method feasibility study has been conducted in two phases, the first stage evaluating a smaller sample of patients and volunteers recruited in London, and then a second phase with a larger sample of volunteers recruited from across the United Kingdom.Trial registration: ISRCTN17586238.

В статье представлен вариант решения задачи выбора метода двоичной (двухклассовой) классификации потока текстовых сообщений (на примере новостных источников - сервиса RSS), поступающих на вход распределенной системы обработки информации. Рассматриваются вопросы, как выбора рационального, с точки зрения потоковой обработки, метода двоичной классификации для подсистемы обработки текстовых сообщений на основе технологии машинного обучения, так и формирования обучающей и тестовой выборок массива текстовых сообщений, необходимых на этапе обучения двоичного классификатора. Представлены результаты экспериментальной проверки полученных значений указанных выборок применительно к рассмотренным методам двоичной классификации. Приводится подход к процессу обучения классификатора для подсистемы обработки текстовых сообщений в распределенной системе потоковой обработки информации. The article presents a variant of solving problem of a method for binary (two-class) classification choosing of a text messages stream (using the example of news sources - the RSS service) entering on input of a distributed information processing system. The issues of both the choice of a rational binary classification method for a text message, from the point of view of stream processing for subsystem based on machine learning technology, and the formation of training and test samples of an array of text messages required at the stage of training a binary classifier are considered. The results of experimental verification of the obtained values ??of these samples are presented in relation to the considered methods of binary classification. An approach to the process of classifier training for text message processing subsystem in a distributed system of streaming information processing is presented.

Over a three-month period (spanning 15 September to 15 December 2011), over 90,000 authentic text messages in French were collected by a group of academics in the Languedoc-Roussillon region of France. This paper retraces the organisation of the data collection, the elaboration of the sociolinguistic questionnaire that donors were invited to fill out, text message data processing procedures and preliminary results. A shift from individual “isolated” text messages to “conversational” SMS exchanges is then studied, in preparation for a new SMS conversational data collection which is due to take place in the near future. This whole process is important for understanding in-depth interactional practices within contemporary digital textuality and should provide insight for pluri-disciplinary approaches.

Background: In China, where follow-up with hospitalized attempters is generally lacking, there is a great need for inexpensive and effective means of maintaining contact and decreasing recidivism. Aims: Our objective was to test whether mobile telephone message contacts after discharge would be feasible and acceptable to suicide attempters in China. Methods: Fifteen participants were recruited from suicide attempters seen in the Emergency Department in Wuhan, China, to participate in a pilot study to receive mobile telephone messages after discharge. All participants have access to a mobile telephone, and there is no charge for the user to receive text messages. Results: Most participants (12) considered the text message contacts an acceptable and useful form of help and would like to continue to receive them for a longer period of time. Conclusions: This suggests that, as a low-cost and quick method of intervention in areas where more intensive follow-up is not practical or available, telephone messages contacts are accessible, feasible, and acceptable to suicide attempters. We hope that this will inspire future research on regular and long-term message interventions to prevent recidivism in suicide attempters.

Diseases in leaves can cause the significant reduction in both quality and quantity of agricultural production. If early and accurate detection of disease/diseases in leaves can be automated, then the proper remedy can be taken timely. A simple and computationally efficient approach is presented in this paper for disease/diseases detection on leaves. Only detecting the disease is not beneficial without knowing the stage of disease thus the paper also determine the stage of disease/diseases by quantizing the affected of the leaves by using digital image processing and machine learning. Though there exists a variety of diseases on leaves, but the bacterial and fungal spots (Early Scorch, Late Scorch, and Leaf Spot) are the most prominent diseases found on leaves. Keeping this in mind the paper deals with the detection of Bacterial Blight and Fungal Spot both at an early stage (Early Scorch) and late stage (Late Scorch) on the variety of leaves. The proposed approach is divided into two phases, in the first phase, it identifies one or more disease/diseases existing on leaves. In the second phase, amount of area affected by the disease/diseases is calculated. The experimental results obtained showed 97% accuracy using the proposed approach.

Mental health treatment providers seek high-impact and low-cost means of engaging clients in care. As such, text messaging is becoming more frequently utilized as a means of communication between provider and client. Research demonstrates that text message interventions increase treatment session attendance, decrease symptomology, and improve overall functioning. However, research is lacking related to the linguistic make up of provider communications. Text messages were collected from previously published articles related to the treatment of mental health disorders. A corpus of 39 mental health treatment text message interventions was composed totaling 286 words. Using Linguistic Inquiry and Word Count (LIWC) software, messages were analyzed for prevalence of terminology thought to enhance client engagement. Clout, demonstrating the writer’s confidence and expertise, and positive Emotional Tone were found to be at a high level within the corpus. Results demonstrated statistical significance for five linguistic variables. When compared with national blog norms derived from Twitter, Clout, Emotional Tone, and use of Biological terminology were found to be at higher rates than expected. Authenticity and Informal terminology were found at significantly lesser rates.

BACKGROUND Culturally-relevant interventions are needed to help American Indian and Alaska Native (AI/AN) teens and young adults navigate common risky situations involving family and friends, including drug and alcohol misuse, dating violence, and suicidality. We R Native – a multimedia health resource for Native teens and young adults – designed an intervention for Native youth, delivered via text message, that includes role model videos, mental wellness strategies, and links to culturally-relevant resources (hotlines, chat-lines, websites, etc.) and social support. OBJECTIVE This study aims to test the efficacy of BRAVE to improve participant’s physical, mental, and spiritual health, their use of mental wellness strategies, their help-seeking skills, and associated factors, including cultural resilience, identity, and cultural pride. METHODS The randomized controlled trial was carried out by the Northwest Portland Area Indian Health Board and the mHealth Impact Lab. The team recruited 2,334 AI/AN teens and young adults nationwide (15-24 years old) via social media channels and text message and enrolled 1,044 to participate. AI/AN teens and young adults enrolled in the study received either: 8 weeks of BRAVE text messages designed to improve mental health, help-seeking skills, and cultural resilience; or 8 weeks of STEM text messages, designed to elevate and re-affirm Native voices in science, technology, engineering, math and medicine (STEM); and then received the other set of messages. Primary and secondary outcomes were tested using linear mixed-effect models and linear regressions. RESULTS A total of 833 AI/AN teens and young adults were included in the analysis. Individuals in the BRAVE and STEM arms showed significant positive trends over the course of the study for all primary outcomes except cultural identity and help seeking behavior. Mean scores were significantly different for health (P<.001), resilience (P<.001), negative coping (P=.027), positive coping (P<.001), self-efficacy (P=.021), and self-esteem (P<.001). Changes in help-seeking self-efficacy were significant for those exhibiting risky behavior at baseline to exit (P=.01). Those who reported positive coping scores at baseline also reported better health on average, but no difference in risky drug and alcohol use (P<.001). The number of participants that used text messages to help themselves increased from 69% at 3-months (427/618) to 75% at 8-months (381/501) (P<.001). Similarly, the number of participants that used text messages to help a friend or family member increased from 22% at 3-months (138/616) to 55% at 8-months (272/498). CONCLUSIONS This is the first nationwide randomized controlled trial for AI/AN teens and young adults to test the efficacy of an mHealth intervention on mental wellness. The findings suggest that culturally-relevant multimedia, mHealth interventions can improve help-seeking behavior. Lessons learned from this study may help other AI/AN-serving organizations, prevention programs, policymakers, researchers, and educators as they support the next generation of AI/AN change-makers.

Abstract Purpose To facilitate the measurement of quality of life in sarcopenia, we set out to reduce the number of items in the previously validated Sarcopenia Quality of Life (SarQoL®) questionnaire, and to evaluate the clinimetric properties of this new short form. Methods The item reduction process was carried out in two phases. First, information was gathered through item-impact scores from older people (n = 1950), a Delphi method with sarcopenia experts, and previously published clinimetric data. In the second phase, this information was presented to an expert panel that decided which of the items to include in the short form. The newly created SFSarQoL was then administered to older, community-dwelling participants who previously participated in the SarcoPhAge study. We examined discriminative power, internal consistency, construct validity, test–retest reliability, structural validity and examined item parameters with a graded response model (IRT). Results The questionnaire was reduced from 55 to 14 items, a 75% reduction. A total of 214 older, community-dwelling people were recruited for the validation study. The clinimetric evaluation showed that the SF-SarQoL® can discriminate on sarcopenia status [EWGSOP2 criteria; 34.52 (18.59–43.45) vs. 42.86 (26.56–63.69); p = 0.043], is internally consistent (α = 0.915, ω = 0.917) and reliable [ICC = 0.912 (0.847–0.942)]. A unidimensional model was fitted (CFI = 0.978; TLI = 0.975; RMSEA = 0.108, 90% CI 0.094–0.123; SRMR = 0.055) with no misfitting items and good response category separation. Conclusions A new, 14-item, short form version of the Sarcopenia Quality of Life questionnaire has been developed and shows good clinimetric properties.

Abstract In this paper, we design the simultaneous wireless information and power transfer (SWIPT) protocol for massive multi-input multi-output (mMIMO) system with non-linear energy-harvesting (EH) terminals. In this system, the base station (BS) serves a set of uplink fixed half-duplex (HD) terminals with non-linear energy harvester. Considering the non-linearity of practical energy-harvesting circuits, we adopt the realistic non-linear EH model rather than the idealistic linear EH model. The proposed SWIPT protocol can be divided into two phases. The first phase is designed for terminals EH and downlink training. A beam domain energy beamforming method is employed for the wireless power transmission. In the second phase, the BS forms the two-layer receive beamformers for the reception of signals transmitted by terminals. In order to improve the spectral efficiency (SE) of the system, the BS transmit power- and time-switching ratios are optimized. Simulation results show the superiority of the proposed beam-domain SWIPT protocol on SE performance compared with the conventional mMIMO SWIPT protocols.
