Software testing is the process of checking software, to verify that it satisfies its requirements and to detect errors. Software testing is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test[1] , with respect to the context in which it is intended to operate. This includes, but is not limited to, the process of executing a program or application with the intent of finding software bugs. Testing can never completely establish the correctness of computer software. Instead, it furnishes a criticism or comparison that compares the state and behaviour of the product against a specification. Software testing should be distinguished from the separate discipline of Software Quality Assurance (S.Q.A.), which encompasses all business process areas, not just testing.

Embedded systems is gaining importance with increasing adoption of 16 and 32-bit processors across a wide variety of electronic products. As consumer expectation from these systems grow, manufacturers are challenged with the following factors before testing this to perfect for market release:

  • Real time responses
  • Separate host (target) systems from development environments
  • Lack of standardization in deployment architectures
  • Lack of established interfaces to systems under testing
  • Stringent Fail-Safe requirements
  • Extremely high cost of isolating and fixing defects

Killexams : Why And How Physicians Can Improve Their Practice Management Strategy Through Outsourcing

Marketing Director at Arthur Lawrence, overseeing the strategic marketing initiatives within the technology and healthcare management space.

On a breezy evening in spring, John and Kevin, two handsome young men, graduated from the same medical college. Twenty-five years later, these two doctors visited their alma mater for a reunion.

A distinction between them became apparent. John was not living up to his potential. He managed everything himself, like supervising staff, front- and back-end services, and calling insurance companies to settle claims. His involvement in administrative tasks delayed patient care. As a result, John often rushed through appointments and spent less time with his patients. Although John was a good practitioner, he couldn’t increase either the patient volume or revenue. His poor work-life balance took a toll on him.

Kevin, on the other hand, had a different approach to managing his practice.

Instead of micromanaging, he partnered with numerous domain experts. He subcontracted administrative tasks so he and the nurses could spend less time on paperwork and more time with the patients. Kevin hired a digital marketing agency to manage his online presence. Kevin secured a healthy work-life balance by delegating clerical responsibilities to seasoned companies.

Unfortunately, John is not alone in feeling work-related stress within the healthcare domain. In my four years of working closely with healthcare practitioners, I have observed that most physicians micromanage instead of taking a patient-centered, outside-in approach. They are often hesitant to delegate administrative tasks or partner up with specialists to ease up their workload.

There are essentially three ways doctors can Improve their overall practice management strategy to ensure better care, Improve the patient experience, optimize their online presence and, most importantly, increase revenue through outsourcing. (Full disclosure: My company offers many of these services.)

1. Partner With An Ancillary Service Provider

If your goal is to provide your patients with convenient in-house diagnostic services and you are thinking from a financial perspective, you may consider partnering with an ancillary services provider. They are excellent outpatient and hospital alternatives, as they tend to offer cost-effective yet equally competent services.

When choosing an ancillary service provider to partner with, you should weigh the below factors:

• The training and skill set of the provider’s technicians, technologists and administrators.

• The quality of the equipment they use.

• How much investment working with them will require in terms of time and money.

• Their expertise and length of experience in any diagnostic services you may require, including screening services like autonomic testing, respiratory and renal scans, eye scans, heart screening, thyroid tests and screening, and so on.

2. Outsource Administration And Practice Management

You may also choose to delegate a portion of administrative services or subcontract the entirety of your practice management to a third party. This can provide doctors and nurses more time for care delivery. Once your administrative systems and processes are in safe hands, your providers may also be able to enjoy a better work-life balance.

Below are some cost-effective approaches in this domain:

Practice Management

Healthcare practice management and consulting companies take care of all the business aspects of your practice, including financial performance, information technology, practice efficiency and efficacy, and human resources, among others.

An ideal practice management consultant will offer you transparency and complete autonomy in using your systems and processes in addition to managing them. This ensures that you are in control of your practice’s operations. Another crucial factor to consider is how well versed they are in the ever-evolving local and federal healthcare laws, policies and legislation.

Revenue Cycle Management (RCM)

A third-party RCM consultant specializes in functions associated with claims processing, payment and revenue generation right from the beginning when a patient makes an appointment.

Before you decide to partner with an RCM expert, consider their length of experience and expertise in:

Front-office management: This includes appointment scheduling and management, benefits verification, authorization and referral management, and leveraging front-office administrative and revenue analytics solutions.

Back-office management: This includes expertise in appropriate billing and claim entries, claim submissions and audits, accounts receivable management, denial management and monthly business analyses and reporting.

• Experience and expertise in insurance credentialing.

• Claim management percentage: look for lower claim denial rates and higher clean claim rates.

Finance And Accounting Service

Hiring a full-time accounting staff is a costlier option, especially to meet a healthcare practice’s finance and accounting needs. A smarter, more cost-effective alternative is to subcontract an external accounting service provider.

It is important to choose a service provider that has relevant medical bookkeeping and accounts management experience. This is because they should be aware of the data privacy and security standards established by HIPAA to be able to remain compliant across functions. Another important aspect is the technology and financial tools the consultants rely on for data management and analytics. QuickBooks, Stripe, Square, Gusto and Oracle NetSuite are some of the tools that service providers tend to leverage to automate your practice’s finance and accounting processes.

3. Hire A Digital Marketing Agency

Most doctors are cautious about utilizing the power of digital marketing to their advantage. A weak online presence can hamper a doctor’s ability to gather ratings and reviews. In contrast, strong and consistent online visibility can not only help you sustain stronger relationships with existing patients but can also help you reach potential patients.

Ask any digital marketing specialists you’re considering working with how they plan to augment your healthcare facility’s reputation and boost footfall within your specific zip code. They should also be able to explain how they help healthcare professionals find areas that aren’t working for future campaigns. Ask them about their plan for creating measurable, accountable and scalable digital and integrated marketing key performance indicators with multiple milestones along the journey. An ideal digital marketing partner will enable you and your practice to leverage all the above areas to build and maintain your practice’s digital presence and positioning.

Not all healthcare practitioners in the U.S. recognize the value of a collaborative advantage for improving their care delivery model and strengthening patient experiences. However, by choosing the right providers, practitioners may be able to enable easier access to quality care, Improve operational and financial efficiencies, and minimize the cost of care.

Killexams : Employee Expectations

The health and safety of the RIT community is a priority. All measures put into place are designed to protect our students, faculty, staff, and the greater community.

Weekly Testing

Weekly testing of employees who are not yet fully vaccinated (2 weeks after final dose) will continue through the week of December 6, 2021.

Weekly tests should be scheduled so that the result is returned within the same calendar week as the test (Sunday through Saturday). Appointments can be scheduled through Remote Medical International’s Covid-19 Testing Services. Please note that there is an option for time zone selection, so be sure to note the time zone that auto fills and correct, if necessary. There will be a link to the Brio website in the confirmation email to sign up for the results portal, which is required before attending the testing.

Generally the test should take no more than 15-30 minutes. Results will be provided during this timeframe, although you do not need to wait for the results. Notification of the results are provided through RMI’s portal, email, or text.

All COVID test results must be submitted each week in Oracle Employee Self-Service. Information on how to upload the results can be found COVID-19 Test Results User Guide. Please note that the test result documentation must be uploaded with the submission.

Returning to Campus

RIT is open for on-campus instruction, research, campus programs, and services. All faculty and staff not currently working on campus are encouraged to return to campus. RIT is no longer operating under reduced capacity guidelines from New York state. All employees working remotely must consult with their supervisors about commencing work back on campus.

Learn more about repopulating campus

Preparing for Spring Semester

Employees working on campus in spring 2021 are required to obtain both a negative COVID-19 test and a 2020/2021 seasonal flu vaccine. The COVID-19 test and flu vaccination are not required of employees who will be on campus for a brief visit no more than once a month (e.g. to pick up mail)​ or if they visit campus and remain outdoors.​ Employees with approved accommodations may also be excused from these requirements.

A new remote work attestation must be entered in Oracle for spring for any adjunct working 100% remotely or any regular faculty or staff employee working 100% remotely outside of New York state.

COVID-19 on Campus

If a student tells an RIT employee that they have tested positive for COVID-19, the employee should tell the student to contact the Student Health Center. The contact tracing teams at RIT and at the Monroe County Health Department carefully review individual’s actions and risks to others following notification of a positive COVID-19 test. They will reach out to those who are genuine close contacts.

Daily Health Screen

The RIT Daily Health Screen has been discontinued as of July 9. All members of the RIT community are expected to self-monitor for any symptoms related to COVID-19 before coming to campus every day.

Returning to Campus

Before returning to campus for the Fall Semester, RIT is requiring all employees to:

  • Get a COVID-19 test and provide proof of a negative result using the RIT Employee Self Serve portal prior to coming to campus.
  • Take an online training session on protecting yourself from COVID-19. Human Resources is sending instructions for taking this course to all employees.
  • Respond to a daily RIT Health Screen, seven days a week, even if you are not coming to campus.

Oracle Employee Self-Serve and attach appropriate documentation. Any new employees/adjuncts will share their vaccination information with their hiring manager, who will fill out the Proof of Vaccination form and send it to hr@rit.edu.

The booster requirement continues to be suspended indefinitely. We are monitoring the development of new boosters. We will evaluate future requirements based on how the virus progresses.

COVID-19 vaccines help protect against severe illness, hospitalization and death. The vaccines also help protect against infection. People who are vaccinated may still get COVID-19, but they are much less likely to experience severe symptoms than people who are unvaccinated.

Individuals that are (will be) physically on the RIT Campus for more than 6 consecutive days or more than 10 days in a rolling 4-week period are required to be fully vaccinated. Ensuring compliance with this requirement is the responsibility of the Contractor/Supplier and the sponsoring department.

Students who are unable to attend class in person due to illness or an order of isolation or quarantine should contact their faculty member for guidance on making up any missed work.   

Students and employees who have symptoms, test positive for COVID-19, or have been in close contact with someone who tests positive should follow the guidance from the New York State Department of Health (DOH).

Employees should contact their primary care physician for guidance and follow the COVID-19 Symptom/Exposure/Absence Process Information for Employees on the HR website for details on reporting requirements related to COVID-19.

Students should notify the Student Health Center of their positive test result by completing the Positive COVID-19 Test Reporting form located in the My Forms section of the RIT Wellness Portal. If a member of an RIT student’s household (roommate, suitemate, housemate, etc.) shows symptoms of COVID-19, that person should be tested. While awaiting test results, that student, if unvaccinated should not go to work or class and instead, should quarantine until the evaluation is complete.

For-cause testing is available in the Student Health Center. Telephone, secure messaging or Patient Chat are contact options. Students who live in RIT housing are required to report any positive test result to the Student Health Center.

COVID-19 has altered many facets of life for members of the RIT community. These changes can take a toll on our emotional well-being and may result in stress, fear, and/or anxiety. Please be aware that the following resources and services are available to support you.

Killexams : Sports News

The Boston Red Sox released outfielder Jackie Bradley Jr. on Thursday. Bradley, 32, rejoined the Red Sox after the team acquired the outfielder and two minor leaguers in a December 2021 trade with the Milwaukee Brewers, giving up slugger Hunter Renfroe. He was hitting .210 with three home runs and 29 RBIs in 92 games for the Red Sox while making $9.5 million this season. "We were hoping, offensively, it was going to be a lot better than last year," manager Alex Cora said. "He had some stretches at home that were good. Obviously, he struggled toward the end. We weren't able to get him to be consistent hitting the ball the other way. This year, there weren't too many strikeouts. But toward the end, there were a lot of ground balls to the pull side. Offensively, it just didn't work out." Bradley, who has a career .228 batting average, was a mainstay for Boston during his first stint with the Red Sox from 2013 to 2020, earning an All-Star nod in 2016...

The Big Idea

The Supreme Court’s decision to overturn the constitutional right to an abortion forebodes courtroom quagmires for America’s tech giants.

Google and Facebook can expect battles over everything from abortion service advertising to location data warrants.

Model legislation proposed by the National Right to Life Committee, which has already attracted the interest of anti-abortion lawmakers in Indiana and South Carolina, would penalize advertising abortion services to people who live in states where the practice is illegal. Texas and Oklahoma allow civilians to sue anyone who helps a resident get an abortion, creating ambiguity around the legality of advertising there.

Activists seeking to help people end their pregnancies in states with restrictions are finding that Facebook and Google have special approval processes for running ads about abortion as well as medications. To block scammers — anyone who might be misrepresenting themselves as an abortion clinic or medication provider— from using their sites, only online pharmacies, telehealth providers and pharmaceutical manufacturers can apply to place ads.

Facebook has removed posts that offer to mail abortion pills without a prescription, citing its policy on regulated goods.

Even though abortion-rights advocates say they have the First Amendment on their side, the regulatory thicket is bound to grow denser, your host reports.

Google already bans abortion advertising in 72 countries where it’s illegal.

Meanwhile, the tech giants have long dealt with law enforcement requests for evidence in criminal cases. Prosecutors looking to prove abortion cases might turn to Google and Facebook for location data.

POLITICO’s Alfred Ng reported that 10 states where abortion is illegal issued a collective 5,764 “geofence” warrants to Google between 2018 and 2020. Such location data shows where and when a mobile device was present and helps police investigate persons of interest at a crime scene.

The high number of requests suggests that law enforcement in states where abortion is restricted are well versed in seeking out location data. To avoid turning over this information, Google has committed to automatically delete geolocation data around abortion and fertility clinics.

Anti-abortion activists are savvy about Google and Facebook’s granular geo-targeting abilities. A Massachusetts ad firm once ran into trouble with the state for targeting people in proximity to abortion clinics with ads encouraging them to take their pregnancies to term. After state Attorney General Maura Healey charged Copley Advertising with violating a Massachusetts consumer-protection law, the firm agreed not to target Bay State health care facilities.

Washington Watch

HEARING TODAY ON PROBLEMS WITH VAS EHR SYSTEM — The Senate Veterans’ Affairs Committee will meet at 3 p.m. today to discuss where the agency’s efforts to modernize its electronic health record system stand. The $16 billion project has been beset with issues since its launch in 2020.

Delays, miscommunication and a dysfunctional rollout have haunted the new system, designed by EHR developer Cerner (now owned by Oracle). The hearing will hopefully elucidate what’s next.

Around the Nation

STATES JOCKEY FOR ARPA-H HEADQUARTERS Congress gave the green light to President Joe Biden’s idea to create a new agency to bolster “high-risk, high-reward” biomedical research when it passed legislation funding the Health and Human Services Department in March.

The law provided $1 billion in seed money but didn’t say where the Advanced Research Projects Agency for Health should be located.

Now, lawmakers and industry groups are lobbying HHS Secretary Xavier Becerra for the headquarters.

So far, 10 states, from California to Massachusetts, are making the case that they have the best mix of companies, universities and government agencies to complement the new agency.

Lawmakers and the Biden administration want the ARPA-H to take more risks and respond more quickly to opportunities than existing agencies that fund health research, like the National Institutes of Health. They hope that will lead to cures, or at least improvements in treatments, for diseases like cancer, diabetes and Alzheimer’s disease.

Background: Becerra has annoyed lawmakers by announcing he wants to put ARPA-H under the NIH budget to take advantage of existing support infrastructure, like human resources. But that doesn’t mean Becerra wants it beholden to NIH or even located near NIH headquarters in Maryland.

House Energy and Commerce Health Subcommittee Chair Anna Eshoo, a California Democrat, wants a clean break with NIH, and the House passed her bill to make ARPA-H an independent agency last month.

It’s unclear whether the Senate will take up the measure or when Becerra will settle on the agency’s home.

UNIFORM TELEHEALTH ACT HEADS TO STATES — An influential commission agreed to propose a bill to states to coordinate state telehealth legislation and expand access to virtual care.

The Uniform Law Commission approved the model legislation after years of deliberation among groups, including the Federation of State Medical Boards, the American Medical Association, the Federal Trade Commission and telehealth groups.

If states enact the legislation, it would align telehealth regulation and add a new registration system to facilitate care across state borders.

Abortion was a point of contention during the proceedings. Some commissioners proposed protecting providers from liability if they offered abortion pills via telehealth appointments, while some hoped the model bill would help law enforcement go after doctors providing abortions.

The commission avoided the issue, a decision that may not hold up as states move to ban or restrict the procedure following last month’s Supreme Court decision.

Data Dive

PATIENT ACCESS TO RECORDS AND BURNOUT Regulations from HHS’ Office of the National Coordinator for Health Information Technology requiring health care organizations to provide patients digital access to their records that went into effect last spring haven’t caused more clinician burnout, researchers at the University of California, San Francisco, and the University of Pennsylvania found.

Health professionals often cite paperwork as a source of stress. But using data from electronic health record giant Epic, the authors of the paper, published in the Journal of the American Medical Informatics Association, found that time spent keeping records didn’t significantly change after the rule change.

Around the World

FUNDING IS DRYING UP FOR DIGITAL HEALTH Funding for digital health is down 32 percent from last quarter and nearly 50 percent from the same time last year, according to a report from CB Insights. This quarter, digital health companies have raised a collective $7.1 billion.

In the U.S., only one company in the category went public this year, Heart Test Laboratories, and overall deal sizes are also smaller than they were last year.

“The volume of companies raising right now is down, as companies with a choice are waiting. Rounds are still getting done, but prices have adjusted,” said Ellie Wheeler, a digital health investor at Greycroft. She expects funding to pick up at the end of the year.

Bucking the trend, funding for digital health in Europe saw a 6 percent increase.

The biggest investment area is in health IT companies, which have attracted $2.8 billion this quarter.

The Next Cures

A VIDEO GAME FOR LUPUS People with a chronic immune disorder who participated in a study published in Lupus were better able to adapt their behavior to changing conditions, showing improved cognitive flexibility after playing a video game from Akili Interactive Labs. Over four weeks, 60 patients with systemic lupus erythematosus demonstrated improved executive functioning and motor speed. SLE is a chronic inflammatory disease that manifests in fatigue and joint pain and can damage the nervous system.

This is just the latest foray into gaming-as-medicine by Akili Interactive. The company was the first to get FDA approval for a video game in 2020. That game, EndeavorRx, helps with attention and focus in kids ages 8 to 12 with ADHD.

The company is looking into using its technology to treat multiple sclerosis, major depressive disorder and autism spectrum disorder as well as acute cognitive dysfunction related to chemotherapy, surgery and Covid-19.

Killexams : Toward A Smarter, Trustworthy And Data-Rich Open Metaverse

Dr. Xinxin Fan is the Head of Cryptography at IoTeX, a startup empowering the future machine economy with blockchain and IoT.

The metaverse has attracted significant attention from business leaders working across various fields, with organizations of all sizes entering the metaverse in different ways. Citi recently said this concept of extended reality could represent an opportunity worth up to $13 trillion by 2030. By combining the physical and virtual worlds persistently and immersively, the metaverse is becoming the next iteration of the internet, known as Web3.

Such an open version of the metaverse would likely be owned by internet communities, instrumented by crypto tokens and governed by community-led entities known as decentralized autonomous organizations (DAOs). The open metaverse enables people to expand their social interactions significantly, including entertainment, commerce, advertising, education, social media, manufacturing, virtual communities and enterprise in general.

An open metaverse application is orchestrated by blockchains and built upon an evolving suite of highly composable technologies covering key services such as identity, computation, communication, storage and asset exchange. In particular, data generated in the physical and virtual world could be utilized for building data-rich metaverse applications, creating more authentic and natural user experiences.

In practice, the realization of a seamless convergence of our physical and digital lives in the metaverse has posed notable challenges for tech leaders. What are the two key technical aspects of connecting the physical world and the metaverse?

Transferring Trusted Data

A data-rich metaverse application is built upon on-chain data directly accessible from blockchains and off-chain data obtained from the physical world. While the decentralized blockchain network secures the on-chain data, the off-chain data is usually provided by third-party services or collected by IoT devices in the physical world. As a result, the trustworthiness of off-chain data becomes critical for building data-rich metaverse applications.

Blockchain oracles provide a practical solution for feeding off-chain data to the metaverse. By querying the APIs exposed by third-party services and IoT platform providers, a decentralized oracle network can retrieve a wide range of real-world data, including digital asset prices, lending rates, climate reports, traffic status and more. Since third-party services and IoT platform providers serve as data aggregators, the data trustworthiness relies on those centralized services.

With respect to IoT data, blockchain oracles can also directly resort to a group of community-driven, globally dispersed smart devices in lieu of querying a centralized IoT platform. While increasing the architectural complexity of blockchain oracles, such an approach eliminates the need for trusted data intermediaries and places trust in IoT devices.

Provided that IoT devices are equipped with state-of-the-art secure hardware and built by following IoT security best practices in the industry, a trusted data collection process can be well ensured. A decentralized oracle network can then feed the trusted IoT data to the specific metaverse application.

The Metaverse And Real-Life Utility

If you think that bringing trusted data from the physical world to the metaverse facilitates developers to create data-rich applications, programming the material world from the metaverse will unleash everyone’s imagination. The robust blockchain and cryptocurrency techniques such as DeFi, NFTs and DAOs enable developers to build metaverse applications that can incentivize real-world entities to complete specific tasks in a transparent and trustworthy manner.

Cryptocurrencies coupled with well-designed token economies provide strong financial incentives for physical world entities participating in metaverse applications. They enable faster growth of an application’s user base and sustainable ecosystem development. Moreover, the token rewards users receive by participating in the metaverse applications can be further invested in a wide range of DeFi products to earn passive income.

In addition, real-world assets and data have recently become some of the most promising tokenized NFTs. Those NFTs represent a novel way of managing assets and data in the physical world. Finally, DAOs have the great potential to revolutionize governance for the metaverse applications by distributing the decision-making power to all participants and minimizing the administration overhead.

Building Your Open Metaverse Strategy

The open metaverse unlocks a whole new realm of possibilities to engage with internet communities and is expected to stimulate business model innovation and create new services in the upcoming years.

The open metaverse is still in early development, and it is difficult to create a comprehensive business strategy in such a dynamic space. For now, business leaders could start exploring this new fast-moving digital landscape by considering the following key business questions.

• Business model: Organizations need to carefully evaluate the impact of building a community-driven, open metaverse application on their existing business models. The application should align well with their business goals.

• Technology readiness: Organizations should understand the technology for building metaverse applications and determine if existing software, hardware and other decentralized components can meet their technical requirements with respect to security, privacy and usability.

• Ecosystem partnership: Organizations should clearly identify the potential partners and collaborators based on the analysis of required technologies and gradually establish business relationships with other ecosystem participants.

• User engagement: The organizations should determine the best approach (e.g., DeFi, NFTs, DAOs or their combination) for incentivizing community members to join their open metaverse applications and achieving long-term and sustainable business growth through new digital services and experiences.

• Market feedback: The organizations should build minimal viable products (MVPs) for their open metaverse applications with a reasonable initial investment and quickly test whether such applications are able to achieve their business goals.

The above approach should help business leaders build their open metaverse strategy effectively without incurring significant costs and risks.

Looking Into The Future

The infrastructure and applications of the open metaverse continue to evolve at a staggering pace and interactively and cyclically towards the ultimate goal of a full-fledged, universal economic system that provides a fair economy for all participants in the value chain.

The open metaverse is a rather complex system. Many technical challenges have yet to be resolved to build a smarter, trustworthy and data-rich open metaverse. Let’s work together to make the vision of it a reality.

Killexams : July 7 coronavirus news

Coronavirus can lead to neurological complications, including delirium, brain inflammation, stroke and nerve damage, a new University College London (UCL) study published Tuesday in the journal Brain finds.

While respiratory symptoms are commonly associated with coronavirus, for some patients in the study, neurological complications were the first and most significant indication that they had contracted the virus.

Of 43 confirmed or suspected Covid-19 patients at the University College London Hospital, researchers identified 10 with delirium, 12 with brain inflammation, eight with cases of stroke and eight with nerve damage.

They include a woman who seemed to recover and was sent home. “She was disoriented and displayed ritualistic behavior such as putting her coat on and off repeatedly. She reported visual hallucinations, seeing lions and monkeys in her house,” the researchers wrote. One patient died of brain-destroying encephalitis.

The researchers called for close surveillance of the rare and sometimes fatal inflammatory disorder called acute disseminated encephalomyelitis (ADEM). They identified nine cases of ADEM, which is prevalent in children, over a five-week period.

“In Greater London… we would expect to see this incidence of cases in five months, which indicates that COVID-19 is associated with an increased incidence of ADEM,” the study states.

The study’s findings suggest that neurological complications were likely a result of immune response to the virus, rather than a result of the virus directly attacking the brain. Researchers say these neurological complications are similar to those related to other coronavirus outbreaks: SARS in 2003 and MERS in 2012.

“Given that the disease has only been around for a matter of months, we might not yet know what long-term damage Covid-19 can cause,” said UCL researcher Ross Paterson. “Doctors need to be aware of possible neurological effects, as early diagnosis can Improve patient outcomes.”

He added that people recovering from the virus should seek professional health advice if they experience neurological symptoms.

The researchers said their study was biased toward severe disease. They called for additional research to assess the neurological and neuropsychological consequences of Covid-19.

Outside experts agree that more research is needed on the topic.

“We’ve already seen that some people with COVID-19 may need a long rehabilitation period – both physical rehabilitation such as exercise, and brain rehabilitation,” said David Strain, a senior clinical lecturer at the University of Exeter Medical School. “We need to understand more about the impact of this infection on the brain.”

Killexams : Why the Vaccine Websites Suck Listen to this episode

S1: Late last week, I was on the Internet losing my mind, I was trying to get my mom covid vaccine appointment in New York State, but the website kept crashing, showing error messages. I’d see an open appointment. And as I clicked on it, it would disappear. After about five hours of frustration and a little yelling, I saw this one woman on Twitter who said she was having success booking appointments. Later, I asked her what her secret was. I noticed in your email to me, you said you were doing a lot of this in incognito mode because you’d learned this trick before. How did you learn that?

S2: This is super dorky, but we it’s totally from booking Disney vacations for my family.

S1: That’s Jessica Allen. She was looking for appointments farther north in New York State than I was, but she had cracked the system using her Disney booking knowledge.

S2: It used to be that you had to book your dining reservation six months before your trip and you had to be on at a specific time in the morning in the dining, reservations would open up and like things are very competitive, just being in incognito mode for whatever reason, like it helps provide you access to really what’s available.

S1: Here’s what it’s like to try to get a vaccine appointment in New York State right now. First, you hit a screen to confirm the person is old enough for a frontline worker, that sort of thing. Then you end up on a page with links to various locations that might have the vaccine, either state run sites or private pharmacies. You pick one and only then can you try to make the genuine appointment. And that’s assuming your browser hasn’t crashed or that the location hasn’t run out of the vaccine. In the meantime, I failed many, many times, but Jessica got really good at it and she figured, why stop with her parents? She kept the websites open, then called up other family members to book them their slots conferenced in seniors who weren’t great at using the Internet and walk them through the screening questions. I had a lot of like 80 year old ladies giggling when I asked them if they were pregnant, you know, she reached out to her neighbors at one point early and Friday, I remembered my neighbor across the road, a school bus driver.

S2: And so he qualified. And so I called him. I said, hey, I feel bad that I didn’t think about this sooner, but are you trying to get an appointment? If if you are, can I help you if you need help? And so I was able to book him right then on the phone and then he called two other people that he knew qualified and told me later that they were both able to get appointments.

S1: All told, how many people do you think you have helped get appointments for? 50. It’s been 50.

S3: Yeah, because of Jessica, 50 people are going to get vaccinated. Seniors, people who aren’t Internet savvy, people who live in rural areas without good broadband. And that’s great. But the fact that it took this effort and the fact that people who don’t have a Jessica in their lives are at a real disadvantage, that is very much not great. Today on the show, why it’s so hard for so many people to sign up for vaccines, why the online systems are failing and how we could make them better at this crucial moment. I’m Lizzie O’Leary, and you’re listening to What Next, TBD, a show about technology, power and how the future will be determined. Stick with us.

S1: Over the course of the past year, a state struggled to get covered data out to the public to update their websites or to schedule testing. There was one group that seemed to be everywhere.

S4: If you put yourself in the shoes of a non-technical decision maker in like a local government, you’ve been handed this urgent priority and you need to make the tech work.

S1: That’s Rafael Lee who directs the health program at UC Digital Response, a collection of volunteers, engineers, user experience designers and technologists who’ve been offering help for free to overwhelmed state governments.

S4: So some state local governments already have technical teams that have the ability to design new services from scratch or adapt open source review vendors. They’re not usually very big teams. Most state governments don’t have these teams and so they often go to the private sector for solutions. And software engineering is this crazy, topsy turvy world where the things that seem really hard are sometimes pretty easy and the things that seem really easy can be pretty hard. So unless you have senior technologists on staff who can help you review your vendors before you sign the contract and pay them money, you’re just going to buy based on the brochure that they provide you and how our state and local governments reacting to the problems with vaccine rollout so far.

S1: I mean, are they frustrated? Is that something that you’re hearing?

S4: I think mostly people are confused. Hmm. It’s a really hard problem to solve. It’s the largest vaccination rollout in modern history. And the reason it’s so complex is primarily because states are following a phased approach that prioritizes different groups of people. But they don’t always know exactly how many doses they’re getting or when they’ll arrive. And when these things aren’t certain, it’s hard to plan ahead. More recently, we’re seeing that the eligibility standards and the enforcement of those standards are changing as states adapt to the situation. And that makes all the technology projects a moving target for the health agencies.

S1: So I guess, yeah, as the standards change, you know, every week, every couple of days, it’s pretty hard to be nimble and respond to that. Exactly. You know, I think from the perspective of people trying to schedule vaccine appointments for themselves or their parents, there’s a lot of frustration. And it’s a sort of overwhelming, singular question. How could they not get this right? There have been months to prepare a lot of systems in place to test this stuff out. What is happening behind the scenes that is is explaining some of these issues.

S4: So every state and county has different needs, but they all face pretty similar challenges and they’re using technology to address other problems. So there’s the part that the public sees and then there’s the part that we don’t really see. So let’s start with the part that we do see. First, there are the informational websites that tell people when they’re eligible for vaccines and where they should go. The CDC has shared guidelines and recommendations about the order in which vulnerable groups of people should be prioritized. But ultimately, each state has the discretion to make its own plan.

S1: And these plans are usually complex enough that they’re hard to communicate succinctly in plain words, which which sort of makes me wonder why do this online at all or why do this, particularly if you’re thinking about seniors and marginalized populations, why not meet them where they are as opposed to sending them to a kind of janky website?

S4: Ideally, you have an overall effort that is able to connect to all your populations. There should be an offline and an online component. The offline components don’t scale very well at all. So, for example, if you had scheduling that was only based on the phone, you’d have everybody calling in all the time to the phone lines and you’d have to scale up the people to handle those phone calls. And that is a very expensive and laborious and tedious operation. So if you have this kind of split response where the people who can get online can go to a website and do it there, then that frees up the phone lines and reduces demand on city hall or the vaccine providers to handle the people who can only get in by telephone, by phone.

S1: And there are other ways technology should be able to help the process of getting vaccines into people’s arms.

S4: There’s also things like reminders. So the Fizer and malaria vaccines are multi dose vaccines and people are going to forget to come back for their second dose unless they get a reminder. I read a study in the UK about the hepatitis A vaccine. In the study, only 11 percent of patients completed their two dose regimen. Wow. So if we send out some reminders, that will definitely help.

S1: But reminders and websites and apps and all the public facing technology are still only part of the effort. There are complex logistics and lots of health data that need to be managed on the back end.

S4: There’s tons of things that we don’t see. So there’s things like vaccine inventory management. The states and local health jurisdictions have to track and manage inventory, by which I mean they need to know where the doses are and which sites are running low. They have to keep track of who has gotten which vaccine. They’re not interchangeable. So if you start with Pfizer, you have to finish with Pfizer and you can’t. Substitute men enough for the second dose. They have to collect patient information ahead of time to assess eligibility. They need to find places to even have vaccination sites. So in some parts of the country, governments are planning temporary pop up, even drivethrough vaccination clinics in addition to the hospitals and pharmacies. And most importantly, they need staff. So you can have all the doses in the world that your vaccination site. But unless you have trained licensed medical staff to put shots and arms, people are not going to get their doses.

S1: All of these things make so much sense what you’re saying. And yet I think, wait, why are we having this conversation in mid-January? These don’t seem like things that are impossible to anticipate.

S4: You’re right. They’re not impossible to anticipate. I think one issue that has plagued the state and local governments that we work with is that it’s been difficult to get a clear picture of who’s making this decision. And in the absence of a unified plan from the federal governments, sometimes it isn’t exactly clear who is responsible for what.

S1: I wonder if you can tell me if states and localities are are hopeful that in a new administration, they might have more clear direction from the federal government?

S4: I think there is a spirit of cautious optimism. So when President Biden unveiled the American rescue plan, civic technologists discovered that it includes more than 10 billion dollars of funding for cybersecurity and information technology. A lot of people are interpreting this as a very positive sign that the new administration is thinking about delivery as well as policy, and they’re willing to put their money where their mouth is and hire more technology experts in the government. So people are hopeful. We’ll see what it looks like in practice.

S1: I think about this moment that we are in. It is. For so many people, hopeful, but I also have heard the incoming director of the CDC warn that another 100000 people could die and we are in this terrifying winter. I guess, I wonder, do you feel hopeful that the scale of users accessing that vaccine information so that they can get vaccines is improving?

S4: I am hopeful. And the reason I’m hopeful is because I saw the same thing happening when governments were setting up testing sites. Hmm. In the beginning, it was pretty confused. There weren’t that many good solutions out there. And governments were trying really hard to figure out who do we partner with, how do we get enough of the materials to even do the tests? How do we partner up with labs? How do we handle the same issues, including scheduling and reminders that we’re facing now? And it’s not perfect now, but we’ve come a really long way.

S1: State governments have made big strides with the help of groups like Rafael’s, and many have had the benefit of time to work out kinks in their testing systems. But still, why is the government relying on volunteer groups to deliver essential services? Yes, this is a huge and unprecedented crisis, but the roots of these tech problems run much deeper than that. After the break, why the government is so bad at tech anyway. Stick with us. At the same time that I was trying to get my mother a vaccine appointment in the New York state system, Hannah Chank was trying to do the same thing for her mom in a different one, the system for New York City.

S5: My mother told me that she had found somebody next door on the app who was going to help her get registered. And I was like, you don’t have to do that. I am a I work in technology. I will do it for you. And I’m thinking this is going to take life even with all of the stuff happening. I thought, well, how hard could it be? Like I could build a page like this shortly. I can figure it out.

S1: Hannah is a public interest technologist at New America. She was part of the U.S. Digital Service and the Department of Homeland Security in the Obama administration. And she’s worked on user experience design for more than a decade. And even she couldn’t figure out how to sign her mom up on the city website.

S6: At the same time, we’re getting all of these things like tweets, like, oh, not enough people are signing up and vaccines are going to spoil and things are being defrosted in.

S5: And I was like, but we’re here in Brooklyn trying to get the appointment with this very nice seventy seven year old lady and we can’t do it.

S6: Ever since they announced that there was going to be a vaccine rolling out, I started saying, what’s going to happen? How is the scheduling going to work, the logistics going to work, how this is going to work from a tech perspective. And then just to find myself like in the middle of that with my mom. Yeah, pretty much my head exploded.

S1: I’ve been through this, too, with both of my parents. And I guess I wonder for you, for someone who has built a career around public interest technology, you’ve worked inside of government tech teams. This must land very differently for you than it does for someone else.

S5: I think that for me, in a weird way, it feels personal in part because, like I know like I I literally know the very people who work for the mayor’s office who could very easily fix the whole situation. There are a bunch of tech teams in New York and they have not been asked to work on this.

S6: We have been preaching the public interest technology gospel for about four years now at New America and saying, like, it’s really bad to not have technologists in government for a whole bunch of reasons. You don’t really want to see all of those things come true. You know, like, yes, we’re saying this is going to be a problem when it actually materializes. It’s almost it just feels terrible.

S1: I asked Hunter to back up to tell me the story of the government’s relationship with digital technology.

S5: I think the story really starts in the 90s where all of a sudden the private sector started to realize, like, oh, we actually need a functional website where people can communicate with us and maybe even like order things and check their order. And maybe that’s like our primary mode of communication, even as people like chat with us.

S7: None of that happened in the government in part because of budget cuts. And they didn’t have the staff, but also government did not see its role as being customer centric. A lot of the mindset in this country is that government will help you if you really need it, but you better really need it and you’ve got to prove how you really need it.

S1: Does that differ in other countries? I mean, how do we compare to some place else that that is also, you know, maybe trying to get people vaccinated or just provide services online?

S7: It is really different from other countries. We had some conversations right around when the Kahrizak was rolling out and we compared notes with the deputy German finance minister because in Germany they had gotten the checks out incredibly fast. And so we want to know how they did that. All of the language is, don’t worry, government is going to be there for you. We’re going to help you. We’re going to get you the money that you need. Just tell us what you need and we will provide it.

S1: Over the last year, there have been a lot of stories about outdated government tech infrastructure that one of the most famous being New Jersey’s unemployment system, written in COBOL programming language from the 60s. When you look at this, how much of the problem do you place at the feet of outdated technology and how much is on a lack of focus about what users need and want?

S7: The outdated technology is really more a symptom than the main issue. It’s it’s the result of not paying attention to keeping tech updated because you don’t think it’s important, because you don’t see it as being integral to your mission. If we’re talking about New Jersey, nobody is sitting there saying, you know, this is going to fall apart because it’s written in a language from the 60s or, you know, maybe we might want to think about investing in making this more customer centric. That’s that’s not part of the language. I don’t want to say anathema, but it is just contrary to how the policy level people think about their role.

S1: Well, how do you make that connection then? When I think about sort of who is tasked with delivering on what the policy people come up with and how it gets from a, you know, digital standpoint to the customer who makes that happen.

S7: So this is, I think, why we are finally getting these conversations about user experience and people are finally paying attention to it because there has not really been a connection in the past. The policy people make the decisions and then the doers implement it. Today, the people on the doing side are like, how? Well, how how do we do that? Because they’re not they’re not equipped.

S1: Some people are going to listen to this interview. And in fact, I’ve seen this reaction on the Internet a couple of times and say just bring in the private sector. Is that a good answer?

S6: That is a terrible answer, really. The private sector is already in. If you think about the fact that all of this work is done by contractors, it’s the same ten people over and over and over again. It’s Deloitte, it’s IBM, it’s Oracle. It’s all of these big tech consultancies they’re already in. They are not looking out for people’s best interest. They are typically looking for how can we make money? How can we write ourselves into an ongoing contract? For example, we’ll license you a piece of technology. We won’t build it for you.

S7: And then you have to pay us licensing fees to maintain this very quickly outdated piece of technology. It’s, of course, a very natural response to say, well, just get Eventbrite or like surely there is scheduling software that someone could use.

S1: Right? This feels like looking for concert tickets.

S5: Right.

S7: Or like any of the other things that we do a million times, like booking on Airbnb or like any other interface where there is a map and you pick a location, then you schedule a thing like we’ve all done that a thousand times, so why can’t it happen in the in government? And part of the issue is that what is happening behind the scenes is actually really complicated.

S8: So there’s a whole question of respecting people’s privacy, but also. Being able to collect the right data so that we know where the vaccine has been distributed, it’s more complicated than just throw the private sector at it. Hannah says that what a lot of users, more well-off users who are trying to make appointments are discovering is the experience of being poor, of needing government services that often just don’t work.

S1: In a story you wrote about this, you wrote that a lot of Americans really only have to interact with government occasionally doing their taxes, go to the DMV, maybe traffic court. But when we are talking about Americans who rely more heavily on government services, the failure of technology is a huge added burden in terms of time and effort required to navigate all of this.

S9: One hundred percent. I think it’s partially just that the world has kept evolving and government has not. But yes, I think an enormous piece of this is that the people who are frequent users of government services are people who are already marginalized or lower income. These are the people who need help. And so, yes, they’re used to it being really awful to interact with government.

S1: So in many ways, the fact that you and I are having this conversation is perhaps because more well-off Americans are noticing this right now because of the pandemic. Absolutely.

S9: Absolutely. The entire population all of a sudden is having this wake up call that everybody else who has been interacting with government for a long time, this can’t possibly come as a surprise to them.

S1: One of the things that I’m really struck by, and this is the failure or what seems like a failure to think about those most vulnerable populations and to think about they the way they might be trying to access these sign-up systems. For example, if your only Internet connection is on mobile and the mobile dropdown menus don’t work, you have no recourse.

S9: Guess that that is that is true. There are a significant number of government services that are designed purely for a laptop or don’t function well on mobile, even though we know from research that a large percentage of the population is actually going to access this via mobile and maybe even over a cellular network, because people don’t have laptops or people don’t have Wi-Fi.

S1: While states like New York and California are struggling to get people signed up and vaccinated, there are places that seem to have hit their stride. When I ask people on Twitter to send me their vaccine sign up stories, I got emails from people in Michigan who had easy experiences. And Hannah says things are looking pretty good actually in Alaska.

S6: In Anchorage, they built a tool that will go and look for appointments at all the different places and then deliver it in one interface. I don’t know if it’s because they have that and they they have a tech team and they are using it. But Alaska is doing really well. And interestingly, they told me that they also gave the tool to North Dakota. North Dakota is also doing really well. So that was wonderful to see that. However, they were able to make that happen. They’re using their tech talent, they’re using their innovation team, and they’re doing it in a way that is open source so that other states can benefit from.

S1: The Bush administration’s goal is 100 million vaccine doses by April. And I wonder when you think about that number and the distribution failures we have seen so far, how would you design a program to reach and enroll the largest number of people possible so that that 100 million doses could maybe happen?

S7: Part of what hasn’t happened is some real data analysis right now, we’ve been handling it as though all 50 states are equitable and all 50 states have the same needs. I don’t know that that’s true. At a bare minimum, just doing some analysis around where it makes sense to vaccinate would be a huge step forward.

S1: And then she had one other thought. Less tech related, more human.

S9: Why can’t we all sign up? This keeps this has been driving me crazy. Like I would like to know when I’m scheduled, even if it’s August, that would just provide me peace of mind. And I as long as you know that an event is going to happen, you can start to plan your life after that. So many people are suffering from depression and all other all the other things that are coming with the pandemic. So if people could, at the very bare minimum, have a date when they’re like, well, at this date, I’m going to be vaccinated, I’ll be fully inoculated and I can restart life, I think that would change people’s attitude a lot.

S10: Honasan, thank you very much. Thank you so much. This was fun. Hannah Shank is the director of Strategy for Public Interest Technology at New America Rafaeli. She is the director of USDA’s Health Program. And Jessica Allen, who heard at the top of the show, lives in northern New York State. And hopefully, by the time you hear this, my mom will have gotten her first shot thanks to a state site Jessica flagged for me on Twitter. TBD is produced by Ethan Brooks and edited by Allison Benedikt and Tori Bosch. Alicia Montgomery is our executive producer. TBD is part of the larger What Next family. TBD is also part of Future Tense Partnership of Slate, Arizona State University and New America. Have a good weekend. Mary Harris will be back on Monday. I’m Lizzie O’Leary. Thanks for listening.
