Participatory Surveillance

BACKGROUND The increase in cell phone ownership in low- and middle-income countries (LMIC) has created an opportunity for low-cost, rapid data collection by calling participants on their cell phones. Cell phones can be mobilized for a myriad of data collection purposes, including surveillance. In LMIC, cell phone–based surveillance has been used to track Ebola, measles, acute flaccid paralysis, and diarrheal disease, as well as noncommunicable diseases. Phone-based surveillance in LMIC is a particularly pertinent, burgeoning approach in the context of the COVID-19 pandemic. Participatory surveillance via cell phone could allow governments to assess burden of disease and complements existing surveillance systems. OBJECTIVE We describe the protocol for the LeCellPHIA (Lesotho Cell Phone PHIA) project, a cell phone surveillance system that collects weekly population-based data on influenza-like illness (ILI) in Lesotho by calling a representative sample of a recent face-to-face survey. METHODS We established a phone-based surveillance system to collect ILI symptoms from approximately 1700 participants who had participated in a recent face-to-face survey in Lesotho, the Population-based HIV Impact Assessment (PHIA) Survey. Of the 15,267 PHIA participants who were over 18 years old, 11,975 (78.44%) consented to future research and provided a valid phone number. We followed the PHIA sample design and included 342 primary sampling units from 10 districts. We randomly selected 5 households from each primary sampling unit that had an eligible participant and sampled 1 person per household. We oversampled the elderly, as they are more likely to be affected by COVID-19. A 3-day Zoom training was conducted in June 2020 to train LeCellPHIA interviewers. RESULTS The surveillance system launched July 1, 2020, beginning with a 2-week enrollment period followed by weekly calls that will continue until September 30, 2022. Of the 11,975 phone numbers that were in the sample frame, 3020 were sampled, and 1778 were enrolled. CONCLUSIONS The surveillance system will track COVID-19 in a resource-limited setting. The novel approach of a weekly cell phone–based surveillance system can be used to track other health outcomes, and this protocol provides information about how to implement such a system.

Cell phones are one of the most challenging forms of contraband for correctional facilities. The size of this problem is difficult to quantify. Confiscation data are only able to tell a partial story. Through the use of a unique data collection effort, this research details the number of contraband cell phones within a facility and offers the first attempt to estimate the gap that exists between the number of contraband cell phones available and the number that are confiscated. In light of the findings, implications for policy and an agenda for research on contraband cell phone market dynamics are provided.

Data Collection And Analysis

Researchers have increasingly used Autonomous Monitoring Units (AMUs) to record animal sounds, to track phenology with timed photographs, and snap images when triggered by motion.  We piloted the use of smartphones to monitor wildlife in the Riverside East Solar Energy Zone (California, USA) and at Indiana Dunes National Park (Indiana, USA).  Both efforts involved establishing remote autonomous monitoring stations in which an Android smartphone was housed in a weather-proof box mounted to a pole, with stations powered by solar panels.  Each smartphone was connected to a Google account, and received its recording/photo schedule daily via a Google calendar connection when in data transmission mode.  Phones were automated by Tasker, an Android application for automating cell phone tasks.  The simple approach described could be adopted by others who wish to use non-proprietary methods of data collection and analysis.

Mobile phones for teenagers turn out to be used more than just a means of ordinary communication, cell phone use in teenagers' daily lives related to lifestyle. The purpose of this study is to find out cell phone use for teenagers. This method was chosen because the issue that was explored was a matter of meaning. Data collection techniques used included observation and interviews. Mobile phones are used as an image of the lifestyle of teenagers buying a mobile phone that is trending with the main reason to look slang, have confidence in front of their friends, and show who they are to others. Mobile phones are very important items in the lives of teenagers. Innovations that are presented in the features available on mobile phones make teenagers increasingly unable to escape from this one object. Based on the results of the study, it can be concluded that cell phone phones are important in teenager’s life; mobile phones are a side of modern life, cell phones as a lifestyle obtained in cell phones when used.

Cati Survey

Internet-enabled smartphones and wireless communication technologies are opening new ways to conduct web-based self-administered data collection for academic or nonacademic research. Considering the relative advantages of self-administration such as the low cost, overall convenience, and collection of better data about sensitive topics, survey researchers are eager to explore conducting national web surveys of the general population via smartphones, especially if they can use probability-based random-digit-dialing (RDD) sampling methods. But questions about the feasibility of such surveys remain. We conducted an experiment using national samples drawn from an RDD wireless sampling frame to compare two administration methods: a smartphone web survey using SMS (text messages) invitations and a cell phone (smartphone or feature phone) survey through computer-assisted telephone interviewing (CATI). This study was conducted using the National Survey of Smoking and Health in South Korea, a country with a very high rate of smartphone ownership. The geographic and demographic representativeness of respondents in the smartphone web mode (self-administered mode) was similar to that of the cell phone CATI survey (interviewer-administered mode), although the completion rate in the former was nearly half that of the latter. A majority of demographic variables and measures of experiences, attitudes, and perceptions of cigarettes or smoking showed significant mode differences for both unweighted and weighted estimates. The total cost of the web survey was about one fifth that of the telephone survey. The results demonstrate the potential of a smartphone web survey as a stand-alone or primary mode of data collection, if carefully designed and implemented.

The development of the hydration stages for electron microscopes has opened up the application of electron diffraction in the study of biological membranes. Membrane specimen can now be observed without the artifacts introduced during drying, fixation and staining. The advantages of the electron diffraction technique, such as the abilities to observe small areas and thin specimens, to image and to screen impurities, to vary the camera length, and to reduce data collection time are fully utilized. Here we report our pioneering work in this area.

Amorphous Structures

Electron tomography is a technique where many projections of an object are collected from the transmission electron microscope (TEM), and are then used to reconstruct the object in its entirety, allowing internal structure to be viewed. As vital as is the 3-D structural information and with no other 3-D imaging technique to compete in its resolution range, electron tomography of amorphous structures has been exercised only sporadically over the last ten years. Its general lack of popularity can be attributed to the tediousness of the entire process starting from the data collection, image processing for reconstruction, and extending to the 3-D image analysis. We have been investing effort to automate all aspects of electron tomography. Our systems of data collection and tomographic image processing will be briefly described.To date, we have developed a second generation automated data collection system based on an SGI workstation (Fig. 1) (The previous version used a micro VAX). The computer takes full control of the microscope operations with its graphical menu driven environment. This is made possible by the direct digital recording of images using the CCD camera.

Session Analysis

This study investigated whether young children with specific expressive language impairment (SELI) learn to combine words according to general positional rules or specific, grammatic relation rules. The language of 20 children with SELI (4 females, 16 males, mean age of 33 months, mean MLU of 1.34) was sampled weekly for 9 weeks. Sixteen of these children also received treatment for two-word combinations (agent+action or possessor+possession). Two different metrics were used to determine the productivity of combinatorial utterances. One metric assessed productivity based on positional consistency alone; another assessed productivity based on positional and semantic consistency. Data were analyzed session-by-session as well as cumulatively. The results suggest that these children learned to combine words according to grammatic relation rules. Results of the session-by-session analysis were less informative than those of the cumulative analysis. For children with SELI ready to make the transition to multiword utterances, these findings support a cumulative method of data collection and a treatment approach that targets specific grammatic relation rules rather than general word combinations.

Purpose The use of real-time recording technology for clinical instruction allows student clinicians to more easily collect data, self-reflect, and move toward independence as supervisors continue to provide continuation of supportive methods. This article discusses how the use of high-definition real-time recording, Bluetooth technology, and embedded annotation may enhance the supervisory process. It also reports results of graduate students' perception of the benefits and satisfaction with the types of technology used. Method Survey data were collected from graduate students about their use and perceived benefits of advanced technology to support supervision during their 1st clinical experience. Results Survey results indicate that students found the use of their video recordings useful for self-evaluation, data collection, and therapy preparation. The students also perceived an increase in self-confidence through the use of the Bluetooth headsets as their supervisors could provide guidance and encouragement without interrupting the flow of their therapy sessions by entering the room to redirect them. Conclusions The use of video recording technology can provide opportunities for students to review: videos of prospective clients they will be treating, their treatment videos for self-assessment purposes, and for additional data collection. Bluetooth technology provides immediate communication between the clinical educator and the student. Students reported that the result of that communication can improve their self-confidence, perceived performance, and subsequent shift toward independence.
