Diagnostic Utility Statistics Calculation:

Example of the information available

Result of:

1) Calculate sensitivity, specificity and total accuracy

2) Calculate negative and positive predictive power

3) Calculate and print positive and negative likelihood ratios

4) Calculate and print kappa statistic

* Sensitivity: the proportion of true positive (TP) results out of all of the true positive (TP) results

* Specificity: the proportion of true negative (TN) results out of all of the true negative (TN) results

* Total accuracy: the proportion of results that are correct in all (TP and TN) results

* Negative predictive value (NPV): the proportion of results that are negative, among those with negative test result, that turn out to be true negative (TN) results

* Positive predictive value (PPV): the proportion of results that are positive, among those with positive test result, that turn out to be true positive (TP) results

* Odds ratio: odds of occurrence of the disease in those with positive test result divided by odds of occurrence of the disease in those with negative test result

* Kappa: kappa statistic

* Reporting Agreement or Concordance: reporting agreement between the two methodsQ:

Authentication does not work when calling REST web service

I have created an API Gateway for our client application. This Gateway application is deployed on Cloudfoundry.
The gateway is working fine. The problem is when I try to access the Gateway application from our client application (mobile). When I try to connect to the REST service, the authentication fails and gives me the following error:
{“error”:”bad_request”,”error_description”:”Missing userId”}

I am using a pre-existing postgres db for user authentication. The postgres schema name and db name are the same as the one used in the gateway.
Gateway is configured like this:
User-Agent: curl/7.19.7 (i686-pc-linux-gnu) libcurl/7.19.7 NSS/3.12.8 zlib/1.2.3 libidn/1.18 libssh2/1.2.6

In a letter to the community, Mayor Scott Silverthorn said he’s asking people to refrain from making these shared photos and videos public in order to protect police officers from harassment and to be mindful of residents who have already been “needlessly” impacted by the violence.

“With the recent incident in Charlottesville, social media postings have done more to jeopardize the safety of our police officers and the community at large than to aid in the healing process,” the letter says.

The mayor noted that his office has been inundated with calls and emails from residents who say they’ve received threats and demands from people asking them to take down posts about the violence, which broke out last weekend in Charlottesville when white supremacists, neo-Nazis and other far-right activists protested the planned removal of a statue of Confederate Gen. Robert E. Lee.

“At the same time, it is important to note that the vast majority of the residents of our city and surrounding areas have voiced their support for the police and all those who serve,” the letter says.

The mayor warned of consequences if people ignore his request.

“We must respect the law and not encourage or contribute to the harassment of our police officers,” the letter says.

But the city of Charlottesville took a different approach. In a statement, the city asked people to share the violence on social media and lamented the lack of ability to hold those who are making threatening comments accountable.

“While law enforcement officers are working to maintain order in our city, it is important to support their efforts and share with them what you see so that officers can track and identify those who may be engaged in criminal acts,” the statement said.

The message was echoed by Charlottesville Police Chief Al Thomas in a separate statement.

“We need to remain calm. We need to pray,” Thomas said. “We need to be able to pray and show love to one another.”в-audio-tracks-for-movies/
