In September 2018, she became a geographic information system (GIS) analyst at Florida Department of Health (DOH) in Tallahassee and worked on the agency's emergency response team during Hurricane Michael and Hurricane Dorian. Jones was a graduate student in the Department of Geography at Florida State University from 2016 through 2018, where she worked on a doctoral dissertation entitled Using Native American Sitescapes to Extend the North American Paleotempestological Record Through Coupled Remote Sensing and Climatological Analysis. In 2015, her research titled Quantifying Extreme Weather Event Impacts on the Northern Gulf Coast Using Landsat Imagery was published in the Journal of Coastal Research. In 2014, she received a master's degree in geography and a minor in mass communication from Louisiana State University, where she won an award the same year from the Association of American Geographers. Newhouse School of Public Communications and Maxwell School of Citizenship and Public Affairs at Syracuse University with dual degrees in geography and journalism in 2012. In her junior year, Jones was removed from class for refusing to stand for the Pledge of Allegiance and led other students to do the same after learning from civil liberties groups she was acting within her rights. She says her experiences in Katrina made her interested in natural disasters. ![]() Jones graduated from Stone High School in 2007, after missing months of school due to the school's destruction during Hurricane Katrina in 2005. She grew up poor, often housing and food insecure. At the age of nine, her family moved to Wiggins, Mississippi, where she spent most of her childhood.

In December 2022, she signed a deferred prosecution agreement admitting guilt to unauthorized use of the state's emergency alert system on November 10, 2020, which had resulted in her home being searched under warrant by state police in December 2020. In May 2022, Florida's Office of Inspector General exonerated the state health officials, finding her claims against the DOH to be unsubstantiated or unfounded. In May 2021, she was granted whistleblower protections while the state investigated her allegations. She was fired from her position in May 2020 for repeated insubordination. She managed the team that created the Florida Department of Health's COVID-19 dashboard using ArcGIS software. Rebekah Jones (born 1989) is an American geographer, data scientist, and activist. ![]()

Neat and relatively compact, the Vantrue E1 is an attractive dash cam that’s capable of recording 2.5K video at 30fps. There are cheaper dash cams out there with fewer features to play with, but if the security of your car is crucial to your daily life, the Pro is hard to beat in terms of protection and overall value. The external camera fares well even in tricky shooting situations, from heavy rain to bright sunshine. This dash cam doesn’t record in 4K, but we found its 1080p video to be perfectly serviceable. Other useful tools include break-in alerts if someone tries to tamper with your car, as well as GPS data logging.

His beard may have been done to replicate the beard of Satoshi Okubo, the composer for Hotel Dusk and Last Window, who had a beard similar to Kyle's. Players can be easily fooled that he has blonde hair in Hotel Dusk: Room 215 and the sequel because it looks very bright when it turns monochrome. Kyle has brown hair, dark gray eyes and a beard. Kyle stands at 6'0" and has a slim but sturdy build. 10.2 Last Window: The Secret of Cape West.But those with enough patience to deal with the sometimes repetitive conversations will be more than rewarded, as the plot builds to a climatic finish, and there are corridors-full of top-notch detective work and puzzles to enjoy. Action freaks may find the subtle, slow-paced, text-heavy nature of the game makes them check out early. Most players will find themselves having a very pleasant stay at Hotel Dusk. Then there's the promise of a date in the hotel bar at 10pm with the foxy lady from room 216. You'll get the chance to snoop around the office at 8pm when you know Dunning will leave it unmanned to watch some hockey. You can also keep track of clues and hints by writing reminders with the stylus in your notebook.Īs for the action, it takes place over just one night, with each of the ten chapters covering different time slots. You'll be blowing dust with the microphone, tapping boxes with the stylus and even closing and then opening the console to tip things up. Some aren't immediately logical, but the hotel is compact enough that you're not left aimlessly wandering for hours looking for the solution. The puzzles are brilliant, too – although we wish there were more of them. When you reach an item or area that can be examined, a magnifying glass icon appears and you're given a 3D interactive view. To move around the hotel, you drag the cursor that represents Kyle with your stylus (or move it with the D-pad) around a 2D map shown on the right-hand screen, while the left gives you a first-person view. In general though, Hotel Dusk is expertly paced, and this gets you through the tedious bits.Īside from reading, the rest of the game involves exploration and solving puzzles. Then you have to go back and have the conversation over again and try different responses. And, in the name of realism, sometimes you don't find out you've messed up until you venture into the lobby and find cop-shy hotel owner Dunning livid because a guest has grassed you up for snooping. This is most frustrating when you have to repeat large sections of the game because you chose the wrong response to a question. Sometimes it can drag on a bit, especially when you just want to move onto the next puzzle, and it does get repetitive. During conversations, Kyle's face is shown on the left screen while the character he's chatting to is on the right.įor the most part, the scripted dialogue is absorbing – typically revealing something the other person might not have wanted to divulge, or hinting at what you should do next. (It's also why we've split the screenshots into single screens in our viewer). At least half of the game demands that you read long conversations with other characters, so it's fitting you have to hold the DS vertically like a book. This also helps you understand the motivation of the characters as you can more easily see the subtle changes of expression during your conversations.Īnother interesting feature is the way Hotel Dusk changes the way you use the DS. The visuals are particularly grown-up, with characters having a pencil-sketched look that makes them seem like they're in a moving graphic novel. There's nothing shabby about its presentation, for example – this is one stylish DS game. Not everything about Hotel Dusk is rundown. But as he investigates, why do so many of the clues point back to a 30 year-old murder mystery, and what's it got to do with the disappearance of his friend, Bradley – the very reason he left the police force? Of course, it doesn't take long before Kyle's rusty detective skills tell him not everything is as it seems. Maybe he'll get the chance to flog some shoddy portable sewing machines while he's there? A disgraced New York cop turned cynical door-to-door salesman, he's been sent to Hotel Dusk to collect a package for a mysterious client. Its owner, Dunning Smith, might not be a cross-dresser but he's definitely hiding some secrets in those low-rent rooms. Out in middle of the Californian desert, Hotel Dusk is one such place. When it comes to holiday accommodation, the Marriots, Hiltons and Holiday Inns of the world might be boring, but we prefer them to the sort of downmarket motels where the owner keeps a loaded shotgun under the counter, and at night, dresses up in his dead mom's frocks. ![]() ![]() ![]() Lung Human body X-ray Chest radiograph Organ, others, lung, anatomy, abdomen png 1040x471px 381.65KB.Idiopathic pulmonary fibrosis Chronic Obstructive Pulmonary Disease Lung, lung, lung, medicine, disease png 1000x1000px 394.71KB.Lung Square Kilometre Array Respiratory disease Legionellosis Health, health, lung, electric Blue, medicine png 735x735px 641.01KB.Lung Respiratory system Respiratory disease Therapy Chronic Obstructive Pulmonary Disease, cough, medicine, disease, pulmonology png 1224x1024px 2.26MB.X-ray Lung Chest radiograph Medical diagnosis Disease, x-ray, service, medical, xray png 1200x800px 1023.79KB.Incentive spirometer Respiratory system Physical therapy Respiratory therapist, incentive, breathing, hospital, spirometer png 1600x1200px 271.23KB.Lung Pulmonology Breathing Medicine Clinic, others, blue, text, logo png 626圆26px 46.15KB.body massage illustration, Physical therapy Manual therapy Alternative Health Services Massage, physiotherapy, furniture, couch, pain png 1080x1080px 426.55KB.human bones illustration, Physical therapy Physical medicine and rehabilitation Clinic Injury, physiotherapy, blue, outdoor Shoe, shoe png 955x389px 464.96KB.Bronchus Lower respiratory tract Lung Pharynx Respiratory system, creative lungs, antler, hand, branch png 578圆16px 106.62KB.Lung Pulmonary circulation Bronchus Disease Heart, creative lungs, fictional Character, medicine, human Body png 558圆80px 240.86KB.Lung Human body Organ Respiratory system Heart, heart, human, medical, cell png 500圆67px 68.76KB. ![]() Acapella Flutter valve Breathing Respiratory system Lung, others, blue, lung, medicine png 748x400px 331.18KB.A dedicated trial using this device is now warranted. Our study has, however, shown early supportive evidence of safety in the attachment of an Atrium Pneumostat to an existing chest drain to ambulate patients with secondary spontaneous pneumothorax. “We do not advise use of pleural vent in patients with secondary spontaneous pneumothorax, and the encouraging results with pleural vent in primary spontaneous pneumothorax are not translatable to this population. This may be related to high rates of treatment failure with the pleural vent and a shorter length of stay in the standard arm than previously cited,” the researchers wrote. “In conclusion, there was no difference on length of stay between patients managed with ambulatory care compared to chest drain attached to underwater seal. Results also showed early and sustained improvements in breathlessness, chest pain and quality of life in both groups. Patients managed with the Atrium Pneumostat valve had no early treatment failures (median length of stay, 1.5 days). The rate of early treatment failure was higher among patients with a pleural vent compared with patients who received standard care (46% vs. Researchers observed no difference in length of stay during the first 30 days: median length of stay was 6 days in the ambulatory care group and 6 days in the standard care group ( P =. The primary outcome was hospital length of stay. In the ambulatory care group, 13 patients were managed with the Pleural Vent (Rocket Medical PLC) and eight were managed with the Atrium Pneumostat valve (Atrium Medical). Type of flutter valve used was based on whether a patient already had a chest tube in place at the time of randomization. Patients were randomly assigned to ambulatory care with flutter valve (n = 21 mean age, 63.4 years 67% men) or standard care with a chest tube attached to an underwater seal (n = 20 mean age, 68.1 years 85% men). The open-label, randomized controlled trial included 41 patients with secondary spontaneous pneumothorax from March 2017 to March 2020. “Pooled results from retrospective studies suggest that flutter valves may reduce hospital length of stay in this patient cohort.”ĭata were derived from Walker SP, et al. Walker, MD, clinical research fellow in the Academic Respiratory Unit at the University of Bristol School of Clinical Sciences at Southmead Hospital, Westbury-on-Trym, U.K., and colleagues wrote. “There are no published prospective studies describing use of flutter valves in patients with secondary spontaneous pneumothorax,” Steven P.

Then, the function executes the query and returns the result. A PostgresHook takes the information from the postgres_conn_id and hooks us up with the CrateDB service. The PostgresHook establishes the connection with CrateDB. The SQL statement gets loaded from a file. The first step is to create the function get_policies that takes as a parameter the logical date. Sql = Path("include/data_retention_retrieve_delete_policies.sql") Pg_hook = PostgresHook(postgres_conn_id="cratedb_connection") """Retrieve all partitions effected by a policy""" The implementation of the corresponding tasks looks as follows: get_policies(ds=None): However, it would be natural to expect that we want to execute a query on CrateDB as an SQLExecuteQueryOperator, but since this operator always returns None as a result, we would not be able to access the query result outside the operator. In our case that would be the list of affected partitions. The most important reason behind choosing this type of operator is the need to pass the query result to the next operator. To implement the query above we use a regular Python method, annotated with to make it executable by Airflow. This is especially useful in case of failing workflow: the next time Airflow will pick up the date on which the job failed. In the query, we use the %(day)s placeholder which will be substituted with the logical execution date. To separate SQL logic from orchestration logic, we save the query as a file to include/data_retention_retrieve_delete_policies.sql. JOIN doc.retention_policies r ON p.table_schema = r.table_schemaĪND p.values < %(day)s::TIMESTAMP - (r.retention_period || ' days')::INTERVAL ![]() TRY_CAST(p.values AS BIGINT)įROM information_schema.table_partitions p The resulting query is constructed as: SELECT QUOTE_IDENT(p.table_schema) || '.' || QUOTE_IDENT(p.table_name), ![]() In CrateDB, information_schema.table_partitions contains information about all partitioned tables including the name of the table, schema, partition column, and the values of the partition. We do this by joining retention_policies and information_schema.table_partitions tables and selecting values with expired retention periods. The first step consists of a task that queries partitions affected by retention policies. Our workflow implementation does the following: once a day, fetch policies from the database, and delete all data for which the retention period expired. To automate the process of deleting expired data we use Apache Airflow. Finally, we store the retention policy of 1 day for demo data in the retention_policies table: INSERT INTO retention_policies (table_schema, table_name, partition_column, retention_period, strategy) VALUES ('doc', 'raw_metrics', 'ts_day', 1, 'delete') The important part is that data should be partitioned: in our case, we partition the table on the ts_day column. PRIMARY KEY ("variable", "timestamp", "ts_day") "ts_day" TIMESTAMP GENERATED ALWAYS AS date_trunc('day', "timestamp"), Next, define the table for storing demo data: CREATE TABLE IF NOT EXISTS "doc"."raw_metrics" ( For now, we will always set it to the value delete. The strategy column is reserved for future implementations of additional data retention policies. Therefore, for each retention policy, we store table schema, table name, the partition column, and the retention period defining how many days data should be retained. The retention policy requires the use of a partitioned table, as in CrateDB, data can be deleted in an efficient way by dropping partitions. PRIMARY KEY ("table_schema", "table_name") To define retention policies we create a new table in CrateDB with the following schema: CREATE TABLE IF NOT EXISTS "doc"."retention_policies" ( In this tutorial, we focus on a more complex use case: the implementation of an effective retention policy for time-series data. In the previous tutorial, we illustrated how to use CrateDB and Apache Airflow to automate periodic data export to a remote filesystem with the infrastructure provided by Astronomer. Specification of a Data Retention Policy in CrateDB Implementing data retention policies in the right way ensures compliance with existing guidelines and regulations, such as data privacy law, optimizes storage space by discarding outdated data and reduces storage costs. Once a data set completes its retention period, it should be deleted or archived, depending on requirements. Written by Niklas Schmidtmer and Marija Selakovic What is a Data Retention Policy?Ī data retention policy describes the practice of storing and managing data for a designated period of time. ![]() |
