BACKGROUND Similar to other populations with highly stigmatized medical or psychiatric conditions, people who hear voices (i.e., experience auditory verbal hallucinations or AVH) are often hard to identify and reach for research. Technology-assisted remote research strategies reduce barriers to research recruitment; however, few studies have reported on the efficiency and effectiveness of these approaches. OBJECTIVE The present study introduces and evaluates the efficacy of technology-assisted remote research designed for people who experience AVH. METHODS Our group developed an integrated, automated/human complementary online recruitment and enrollment apparatus which incorporated Google Ads, online screening, identification verification, and hybrid automation and interaction with live staff. We examined the efficacy of that apparatus by examining (1) the number of online ad impressions (i.e. number of times the online ad was viewed), (2) clicks on that ad, (3) engagement with online research materials, as well as the extent to which it succeeded at representing a broad sample of individuals with AVH, assessed through the self-reported AVH symptom severity and demographic representativeness (relative to the U.S. population) of the sample recruited. RESULTS Over an 18-month period, our Google Ads were viewed 872,496 times and was clicked on 11,183 times. A total amount of $4,429.25 was spent on Google Ads, resulting in 772 individuals who experience AVH providing consent to participate in an entirely remote research study ($0.40 per click on the ad, and $5.73 per consented participant) after verifying their phone number, passing a competency screening questionnaire, and providing consent. These participants reported high levels of AVH frequency (88.1% daily or more), distress (91.3%) and functional interference (92.4%). They also represented a broad sample of diversity that mirrored U.S. population demographics. Approximately a third (34.9%) of participants had never received treatment for their AVH and, therefore, were unlikely to be identified via traditional clinic-based research recruitment strategies. CONCLUSIONS Online procedures allow for time-saving, cost-efficient, and representative recruitment of individuals with AVH, and can serve as a model for future studies focusing on hard-to-reach populations.

Introduction: There are 46 million individuals living in rural America that require unique consideration for rural health research. Recruitment of research participants from disparity groups can be difficult as these groups can be hard-to-reach. In particular, strategies for reaching rural-dwelling Americans with disabilities are not well-documented. Furthermore, researchers sometimes underestimate the time and effort needed to recruit participants from hard-to-reach populations. The purpose of this article is to report the methods used to recruit 12 rural-dwelling adults with disabilities into a qualitative study. Method: The recruitment strategies discussed in this article were used in a grounded theory study. Results: Fifty percent of the sample in this study was recruited via a community gatekeeper, 33% responded to a classified advertisement, and 17% were recruited via the researchers’ professional networks. Discussion: Lessons learned yield insights as to effective recruitment methods for rural dwellers as well as other hard-to-reach populations.

In this contribution we present for the first time a continuous process for the production of highly active Pt catalysts supported by carbon nanotubes by use of an electrically heated tubular reactor. The synthesized catalysts show a high degree of dispersion and narrow distributions of cluster sizes. In comparison to catalysts synthesized by the conventional oil-bath method a significantly higher electrocatalytic activity was reached, which can be attributed to the higher metal loading and smaller and more uniformly distributed Pt particles on the carbon support. Our approach introduces a simple, time-saving and cost-efficient method for fuel cell catalyst preparation in a flow reactor which could be used at a large scale.

BACKGROUND: The Human-Centered Design methodology advocates VR prototyping, as an effective tool to evaluate concepts in a cost-efficient, time-saving way. It is the question of whether it works in the development of a product intended to increase privacy while flying. OBJECTIVE: The current study aims at the application of virtual reality on the evaluation of a new privacy bubble called PRIVA for the passenger cabin. METHODS: An interactive VR was created and aligned with the HTC VIVE headset. 40 participants took part in the experiment as well as in the post-experiment survey. RESULTS: The concept was in overall, desirable as it was perceived to be more private, comfortable, satisfactory, effective, and appealing to participants compared to the current seat experiences. It was also perceived as more satisfactory with regards to the activities. CONCLUSIONS: The VR was effective, although there are limitations, the product seems promising and should be developed further.

The defense economy as an economy that has an important role, of course, in its journey faces challenges, especially the low national Research and Development budget of <1% of GDP/Per Capita. Director-General of Research and Development (R&D) Kemenristekdikti Muhammad Dimyati previously said that Indonesia's research growth in the last four years had grown rapidly. Based on 2017 data from the Ministry of Research, Technology and Higher Education, Indonesia's research budget is only 0.25 percent of total GDP, if converted into IDR 30.78 trillion. The second challenge is the entry of the digital era which must be responded wisely and anticipated as the 4.0 industrial revolution in the development of science. The purpose of this study is to describe more about how research & development and the industrial revolution 4.0 are in building a defense economy. In this study, the authors used data analysis techniques with a qualitative descriptive analysis strategy model. The results of the research show that the results of research and development funds are used to innovate to support increased productivity. As a result, the country's production performance has improved and boosted economic growth. The Industrial Revolution 4.0 makes work done by individuals or companies more effective and efficient. With this efficiency and effectiveness, the economy will increase and automatically the defense will also increase. So research & development and industrial revolution 4.0 in practice can build and strengthen the existing defense economy in a country.

Product Costs

Problem/Issue: Product costs are a portion of the annually increasing costs of medical care. With diligent analysis of product costs, including the cost of time to use the product, the surgeon can reduce these spiraling costs. The purpose of this study was to provide the surgeon with the necessary information to make informed decisions about time- and cost-efficient products. Materials and Methods: This study involved phoning, faxing, or e-mailing hospitals and anesthesia groups across the United States to obtain time-dependent costs in the hospital operating room. Operating room fees charged by the hospital and anesthesiologist professional fees are included. Various products were then relatively compared with the time needed to prepare, use, or apply the product. Time and cost factors were then compared in order to ascertain the most time- and cost-effective products. Findings: The findings revealed an average of $62 per minute (rounded to the closest dollar) for the hospital operating room fee (range $21.80–$133.12) and $4 per minute for the anesthesiologist professional fee (range $2.20–$6.10), with a total of $66 per minute. This figure represents a marked increase from the 1991 rate of $20 per minute. Generalizations from this study indicate that time-cost efficiency is seen more so in kits (trays) than in nonkits and more so in disposables than in durables. Products that require fewer people are more time-cost efficient than those that require more people, and products that require fewer steps are more time-cost efficient than those that require more steps. Specific findings included time and cost dominance for the following products: staples over sutures, direct-current cautery over alternating-current cautery, syringes over Dermajet or Madajet, MagneSplint over suturing the nasal septum, aluminum-Velcro or aluminumfoam Denver Splint and Xomed Bridgemaster over any of the polypropylene heat-sensitive splints, Rhino Rocket and Merocel over Vaseline gauze, Brennan RhinoCath over manual blood removal, 1-piece Biplane liposuction cannulas over any 2-piece type, Doyle ear-dressing kit over component parts, Dale nasal dressing over component parts, preformed implants over manual forming, and Denver Splint kits over component parts. Conclusions: Each hospital or private suite will have different charges, and the range of product choices for each surgeon will be different. However, the principle is the same: If you save time, you will save money. In addition to the monetary benefit, the patient will be safer and receive less anesthesia, and the surgeon will have more time for his or her own social or professional life. Each surgeon should analyze the product choices and choose those products that will deliver quality care in less time. To save more than $100 000, the surgeon has to save only approximately 7 minutes per case on 250 cases.

Background: Multi-infarct dementia (MID), a prominent subtype of vascular dementia (VaD), has only achieved recognition in the last 4 decades. Since its original description, the characterization, etiological understanding, and therapeutic direction of MID and other VaD subtypes has progressed at an astounding rate. Summary: This paper divides the landmark discoveries and emergence of new research strategies for MID into decade-defining patterns so that a condensed picture of the total history of MID and its eventual inclusion as a VaD subtype emerges. This paper follows the first descriptive decade, a shift to a preventative focus, a renewed interest coinciding with timely advances in research technology, and a hopeful return to treatment possibilities for VaD. Key Message: Concisely tracing the historical lineage of the modern understanding of MID, both as a singular entity and as part of the VaD con­stellation of disorders, provides a novel perspective on the foundation upon which future advances in combating vascular contributions to dementia will be based.

Natural Symmetry

Techniques for three-dimensional reconstruction of macromolecular complexes from electron micrographs have been successfully used for many years. These include methods which take advantage of the natural symmetry properties of the structure (for example helical or icosahedral) as well as those that use single axis or other tilting geometries to reconstruct from a set of projection images. These techniques have traditionally relied on a very experienced operator to manually perform the often numerous and time consuming steps required to obtain the final reconstruction. While the guidance and oversight of an experienced and critical operator will always be an essential component of these techniques, recent advances in computer technology, microprocessor controlled microscopes and the availability of high quality CCD cameras have provided the means to automate many of the individual steps.During the acquisition of data automation provides benefits not only in terms of convenience and time saving but also in circumstances where manual procedures limit the quality of the final reconstruction.
