🔗 Film 🔗 Film/Filmmaking

Soundies are three-minute American musical films, produced between 1940 and 1947, each displaying a song, dance, and/or band or orchestral number. Produced professionally on 35 mm black-and-white film, like theatrical motion pictures, they were printed on the more portable and economical 16 mm film.

The films were shown in a coin-operated "movie jukebox" named the Panoram, manufactured by the Mills Novelty Company of Chicago. Each Panoram housed a 16 mm RCA film projector, with eight Soundies films threaded in an endless-loop arrangement. A system of mirrors flashed the image from the lower half of the cabinet onto a front-facing screen in the top half. Each film cost 10 cents to play, with no choice of song; the patron saw whatever film was next in the queue. Panorams could be found in public amusement centers, nightclubs, taverns, restaurants, and factory lounges, and the films were changed weekly. The completed Soundies were generally made available within a few weeks of their filming, by the Soundies Distributing Corporation of America.

Several production companies filmed the Soundies shorts in New York City, Hollywood, and Chicago: James Roosevelt's Globe Productions (1940–41), Cinemasters (1940–41), Minoco Productions (owned by Mills Novelty, 1941–43), RCM Productions (1941–46), LOL Productions (1943), Glamourettes (1943), Filmcraft Productions (1943–46), and Alexander Productions (1946) led by William D. Alexander). The performers recorded the music in advance, and mimed to the soundtrack during filming.

The movie-jukebox idea developed several imitations and variations of the technical design; the most successful of these imitators were the Techniprocess company (managed by Rudy Vallee) and the Featurettes company, which used original novelty songs and usually unknown talent (17-year-old Gwen Verdon appears in a couple of the Featurettes as "Gwen Verdun"). As Soundies quickly gained most of the market for jukebox films, the other companies disbanded, and some sold their films to the Soundies concern.

🔗 Cognitive science

Soar is a cognitive architecture, originally created by John Laird, Allen Newell, and Paul Rosenbloom at Carnegie Mellon University. (Rosenbloom continued to serve as co-principal investigator after moving to Stanford University, then to the University of Southern California's Information Sciences Institute.) It is now maintained and developed by John Laird's research group at the University of Michigan.

The goal of the Soar project is to develop the fixed computational building blocks necessary for general intelligent agents – agents that can perform a wide range of tasks and encode, use, and learn all types of knowledge to realize the full range of cognitive capabilities found in humans, such as decision making, problem solving, planning, and natural language understanding. It is both a theory of what cognition is and a computational implementation of that theory. Since its beginnings in 1983 as John Laird’s thesis, it has been widely used by AI researchers to create intelligent agents and cognitive models of different aspects of human behavior. The most current and comprehensive description of Soar is the 2012 book, The Soar Cognitive Architecture.

🔗 United States 🔗 Crime 🔗 Statistics

In September 2013, the incarceration rate of the United States of America was the highest in the world at 716 per 100,000 of the national population. While the United States represents about 4.4 percent of the world's population, it houses around 22 percent of the world's prisoners. Corrections (which includes prisons, jails, probation, and parole) cost around $74 billion in 2007 according to the U.S. Bureau of Justice Statistics.

At the end of 2016, the Prison Policy Initiative estimated that in the United States, about 2,298,300 people were incarcerated out of a population of 324.2 million. This means that 0.7% of the population was behind bars. Of those who were incarcerated, about 1,316,000 people were in state prison, 615,000 in local jails, 225,000 in federal prisons, 48,000 in youth correctional facilities, 34,000 in immigration detention camps, 22,000 in involuntary commitment, 11,000 in territorial prisons, 2,500 in Indian Country jails, and 1,300 in United States military prisons.

🔗 Computer science 🔗 Mathematics

A negative base (or negative radix) may be used to construct a non-standard positional numeral system. Like other place-value systems, each position holds multiples of the appropriate power of the system's base; but that base is negative—that is to say, the base b is equal to −r for some natural number r (r ≥ 2).

Negative-base systems can accommodate all the same numbers as standard place-value systems, but both positive and negative numbers are represented without the use of a minus sign (or, in computer representation, a sign bit); this advantage is countered by an increased complexity of arithmetic operations. The need to store the information normally contained by a negative sign often results in a negative-base number being one digit longer than its positive-base equivalent.

The common names for negative-base positional numeral systems are formed by prefixing nega- to the name of the corresponding positive-base system; for example, negadecimal (base −10) corresponds to decimal (base 10), negabinary (base −2) to binary (base 2), negaternary (base −3) to ternary (base 3), and negaquaternary (base −4) to quaternary (base 4).

🔗 Norway

Norwegian Constitution Day is the national day of Norway and is an official public holiday observed on May 17 each year. Among Norwegians, the day is referred to simply as syttende mai (lit. "seventeenth May"), Nasjonaldagen (The National Day) or Grunnlovsdagen (The Constitution Day), although the latter is less frequent.

🔗 Psychology 🔗 Disability

Working memory training is intended to improve a person's working memory. Working memory is a central intellectual faculty, linked to IQ, ageing, and mental health. It has been claimed that working memory training programs are effective means, both for treating specific medical conditions associated with working memory deficit, and for general increase in cognitive capacity among healthy neurotypical adults.

Individual studies of the topic show different, and sometime contradictory, results, and as one meta study puts it, asking the question “Does cognitive training improve intelligence?” is as inappropriate as asking “Does medicine cure disease?”, since none of them specify which particular intervention (which medicine or working memory training program) is being evaluated, for alleviating which condition is it applied (ADHD, stroke, general cognitive improvement etc.), and under what circumstances is it administered (selection criteria, adherence rate, outcome variables etc.).

In an influential metastudy from 2012, highly critical to cognitive training, analysed 23 studies with 30 group comparisons, and concluded that clinical memory training programs produce reliable short-term improvements in working memory skills in children and adults with ADHD, but also that there is no evidence that such effects can be maintained long-term without additional follow-up training. Three years later, another metastudy reached the opposite conclusion, that working memory training does have consistent and useful effects, not just on the type of working memory tests that are practiced, but also at other non-trained tasks and everyday life. Since then, a range of additional clinical experiments have been completed, with larger sample sizes, clearly defined control groups, and more uniform treatment of outcome variables. While the evidence is still far from unanimous, there are several experimental studies of working memory training that have shown beneficial effects for people with ADHD, those who have suffered stroke or traumatic brain injury, children who have undergone cancer treatment, as well as for normally developing children.

On 17 September 2024, communication pagers simultaneously exploded across Lebanon and Syria in an apparent coordinated attack. Many of the pagers were owned by members of the Hezbollah militant group. Eighteen people were confirmed killed: eleven in Lebanon (including a child and at least two Hezbollah members) and seven in Syria. Around 4,000 people were reportedly injured, including Hezbollah members and civilians.

The blasts affected several Hezbollah strongholds, including Beirut's Dahieh suburb, southern Lebanon, and in the Beqaa Valley. Over 500 of the group's militants lost their eyesight. They called the incident the organization's "biggest security breach yet" and accused Israel of responsibility.

A day after Hamas launched its October 7 attacks on Israel in 2023, the Iranian-backed organization Hezbollah joined the conflict in support of Hamas by firing on Israel. This led to a series of cross-border military exchanges between Hezbollah and Israel. In February 2024, the secretary-general of Hezbollah, Hassan Nasrallah, told the group's members to use pagers instead of cell phones, claiming that Israel had infiltrated their cell phone network. Hezbollah then bought a new brand of pagers that were recently imported to Lebanon.

Earlier on the day of the explosion, Israel's domestic security agency, the Shin Bet, announced it had thwarted a Hezbollah plot to assassinate a former senior defense official using an explosive device.

Around 150 hospitals across Lebanon received victims of the attack, which saw chaotic scenes.
