![]() When using a shared notebook at the same time as other authors, you can achieve a better collaboration experience by having users make notebook additions on separate pages or in their own sections. Learn more about resolving misplaced sections in OneNote. To resolve this, open OneNote on the original computer or device where the “missing” notes were first added or revised, and use the preceding steps to force a sync.įor example, if you created a new section on your laptop but can’t yet see the changes on your desktop computer, go back to your laptop, open OneNote, and then use the preceding steps to force sync the notebook. If your notebook appears to be missing pages or an entire section, this can occur when such content was never fully synced before the notebook was closed where the changes were originally created. Tap and hold on the notebook name in the Notebooks list, and then tap Sync Notebook. A progress marker will appear at the top of the list.

Here’s how to manually force notebook synchronization in the different versions of OneNote: Many unexpected sync problems can usually be resolved by forcing a sync as soon the network is available again. OneNote will automatically store pending changes to your notebooks whenever you are offline and then sync those changes as soon as a network is available again. If you're using OneNote at work, you can request more storage from your OneDrive for Business or SharePoint administrator. You can then consider splitting up a large notebook section into multiple ones or purchasing more storage. ![]() If you do reach your file size limit, OneNote will notify you. You can still reference such content by inserting a link to it instead of directly embedding the content in your notes. Although it can be hard to tell exactly how much content has been added, especially if you've shared your notebook with other people, you and your collaborators can keep some obvious file sizes in mind - for example, by not inserting multiple video files that are several gigabytes in size into the same section, or generally not overloading sections with unnecessary media content. These limits determine how large your notebook sections can get, so you’ll want to make sure that you don’t reach or exceed this limit. On SharePoint and OneDrive for Business, the storage limit is configurable by the administrator, but it will typically have a limit of 15 GB or less. For example, on a personal OneDrive account, the free storage limit is 5 GB. Both OneDrive and SharePoint have file size limits that can impact the maximum size of your OneNote sections. OneNote stores your notebook sections as individual files. However, even when OneNote handles all of the syncing of notes between your computer and your devices, there are a few best practices you can follow to make sure you have the best experience. This means you should never need to manually move files around, like you might be used to with traditional computer files in File Explorer on a Windows PC, or in a Finder window on a Mac. If you are a Windows user, you can rely on this app to backup OneNote to Google Drive easily.No matter what version of OneNote you use, your notebooks are designed to be saved and synced automatically by the OneNote apps themselves.

She also alerts the responsible authorities to notice, accept, and have some action and responsibility the welfare of refugees. There is someone who thinks about them and who can bring effort to raise awareness about their problems in popular culture because of the ongoing crises in the Middle East. The social function of this poem is that she send a strong message to refugees making them know that they are not alone, by giving them a voice which needs to be heard. Do not give up, but believe circumstances will get better. The speaker insinuates that you can run when things get wrong but this will be a part of your memory forever. In addition she reveals that there is no replacement for home and this is natural it can’t be made or taken away. She therefore feel a lot of empathy for those asylum seekers. I believe that Warsan Shire as women understands deeply the implication of driven out of one’s home. It elaborates the racism attitude of some of the receiving countries which uses bad words like black refugees, dirty immigrants, asylum seekers and suckers to expose the attitude of hosting countries.one of the metaphor uses in the poem when referring to refuges for example, “A limb torn off” (Shire, 63) creates empathy for the refugees. Stanza six of the poem shows the use of vulgar language. They face problems and experience lack of food which is not their choice, and at one point speaker also says she was raped during journey. This reveals that travelling is not a pleasurable activity or vocation for them, however it is a UN desirable event occurring as a result of un conducive living environment. “No one spend days and nights in the stomach of a truck” (Shire, 29). When the evoked people transit to new borders to seek for safe place or asylum the hosting countries do not show their positive behaviour for the refugees.Īnother image created through metaphor is the personification of the truck as a death place.

Her poetry has been translated into Italian, Spanish and Portuguese. In 2012 she represented Somalia at the Poetry Parnassus, the festival of the world poets at the Southbank, London. She is the current poetry editor at SPOOK magazine. Her poems have been published in Wasafiri, Magma and Poetry Review and in the anthology ‘The Salt Book of Younger Poets’ (Salt, 2011). Born in 1988, Warsan has read her work extensively all over Britain and internationally – including recent readings in South Africa, Italy, Germany, Canada, North America and Kenya- and her début book, ‘TEACHING MY MOTHER HOW TO GIVE BIRTH’(flipped eye), was published in 2011. Warsan Shire is a Kenyan-born Somali poet, writer and educator based in London. ![]() The first, in the 1970s, involves wealthy Cuban-born rum executive Jorge ( Adan Canto) and flight attendant Leslie ( Radha Mitchell). Adapted loosely from Eric Gregory's nonfiction book All My Tomorrows, it follows the evolution of two romances with themes related to illness, death, grief, and hope. Sure, it’s got its clunky bits, but those only make it better suited for a night on the couch with sweatpants and some rosé.Parents need to know that 2 Hearts is a romantic mystery based on real events that finds a positive outcome from tragedy. As it stands, it’s an unapologetically high-femme distraction that’s better than your average Lifetime thriller. If “Torn Hearts” had pushed itself a little harder, it could have ascended into camp heaven, and maybe become a cult classic. But then why have eyeballs floating in jars full of fluid that's the color of cotton candy, and Sagal proclaiming that she’s got “the right accessory for any outfit” right before she grabs a hot-pink shotgun from her wallpapered closet? And given the potential for mockery inherent in the “hagsploitation” formula, it makes sense that Grant didn’t want to turn her actors into caricatures (if, indeed, that’s the reason for the disconnect). Compared to the setting, the performances are restrained, and Sagal in particular stays naturalistic even when the script goes over the top. Honestly, the most disappointing thing about “Torn Hearts” is that it doesn’t fully embrace its campy potential. But while the big hair and pasted-on Tennessee accents are delicious, they serve mostly as a backdrop for the more grounded drama between Jordan and Leigh as they struggle to overcome their differences and survive Harper’s violent, delusional scheme. The production design, meanwhile, makes up for its budgetary limitations with a heavy dose of tongue-in-cheek redneck glamor: Harper’s dusty mansion-which doubles as a tomb for her sister/bandmate Hope, the Dolly to Harper’s Emmylou-is dotted with farcical details, like Hope’s fuschia urn and the ‘90s-style portraits of Hope and Harper that dominate nearly every room. “Torn Hearts” comes from Blumhouse’s more modestly budgeted TV division, a disadvantage that shows mostly in the underwhelming SFX makeups. Both will be revealed, in a vicious, booze-fueled creative and personal reckoning draped in sequins and tooled leather. Leigh and Jordan have an ulterior motive for their visit, and Harper has an ulterior motive for letting them in. With hopeful hearts and a charming sense of naivete, they ring the buzzer and ask: Would Harper be willing to give them some advice on making it as a woman in a man’s world? The gate swings open, locking with a loud click behind them. Using intel obtained from the aforementioned cads, Leigh and Jordan find Harper tucked away at the end of an old dirt road behind a pink mailbox and a wrought-iron gate overgrown with weeds. Instead, she suggests that they track down their idol, reclusive country legend Harper Dutch (Sagal), and somehow persuade her to record a song with them. Fed up with the boys’ club, Jordan talks Leigh into ditching a recording session set up by Leigh’s also-caddish boyfriend/manager Ritchie ( Joshua Leonard). As the film opens, the pair is angling for a spot opening for a caddish pop-country singer who waits until after he and Jordan hook up to tell her that the label has opted for an “all-guys tour,” and Torn Hearts is not invited. That being said, “Torn Hearts” is less explicitly feminist than last year’s “Lucky,” co-written by Grant and director Natasha Kermani.Īlexxis Lemire and Abby Quinn star as Leigh and Jordan, the lead singer and songwriter, respectively, of rising Nashville duo Torn Hearts. The film’s male characters are peripheral and largely irrelevant, important only in terms of fueling the conflict between the female leads. Written by newcomer Rachel Koller Croft and helmed by actor-turned-director Brea Grant, “Torn Hearts” easily passes the Bechdel test. “Torn Hearts” takes place within Nashville’s country music scene, a novel setting for a horror movie that also provides ample opportunities for social commentary.

The series was popular throughout the 1930s. From that point on, she was crowned "The Queen of the Animated Screen". īetty Boop was the star of the Talkartoons by 1932 and was given her own series that same year, beginning with Stopping the Show. At least 12 Screen Songs cartoons featured Betty Boop or a similar character. Īlthough Betty's first name was assumed to have been established in the 1931 Screen Songs cartoon Betty Co-ed, this "Betty" is a different character, which the official Betty Boop website describes as a "prototype" of Betty Boop. Today, Betty is voiced by Sandy Fox and Cindy Robinson. Later, several different voice actresses performed the role, including Kate Wright, Bonnie Poe, Ann Rothschild (also known as Little Ann Little), and especially Mae Questel, who began voicing Betty Boop in Bimbo's Silly Scandals (1931), and continued with the role until 1939, returning nearly 50 years later in Disney's Who Framed Roger Rabbit (1988). Her floppy poodle ears became hoop earrings, and her black poodle nose became a girl's button-like nose.Ī colorful Betty Boop in Poor Cinderella, 1934īetty was first voiced by Margie Hines. By the release of Any Rags, Betty Boop was forever established as a human character. While much credit has been given to Grim Natwick for helping to transform Max Fleischer's creation, her transition into the cute cartoon girl was also in part due to the work of Berny Wolf, Otto Feuer, Seymour Kneitel, "Doc" Crandall, Willard Bowsky, and James "Shamus" Culhane. Within a year, Betty made the transition from an incidental human-canine breed to a completely human female character. In individual cartoons, she was called "Nancy Lee" or "Nan McGrew"-derived from the Helen Kane film Dangerous Nan McGrew (1930)-usually serving as a girlfriend to studio star Bimbo. Betty Boop appeared as a supporting character in ten cartoons as a flapper girl with more heart than brains. Clara Bow is often given credit as being the inspiration for Boop, though Fleischer told his artists that he wanted a caricature of singer Helen Kane, who performed in a style shared by many performers of the day–Kane was also the one who sued Fleischer over the signature "Boop Oop a Doop" line. Inspired by a popular performing style, but not by any one specific person, the character was originally created as an anthropomorphic French poodle. Although she was toned down in the mid-1930s as a result of the Hays Code to appear more demure, she became one of the world's best-known and most popular cartoon characters.īetty Boop made her first appearance in the cartoon Dizzy Dishes, released on August 9, 1930, the seventh installment in Fleischer's Talkartoon series. ![]() She has also been featured in comic strips and mass merchandising.Ī caricature of a Jazz Age flapper, Betty Boop was described in a 1934 court case as "combin in appearance the childish with the sophisticated-a large round baby face with big eyes and a nose like a button, framed in a somewhat careful coiffure, with a very small body of which perhaps the leading characteristic is the most self-confident little bust imaginable".

Rubbing, lip seals can’t fully protect the bearing from moisture or particle ingress, which ultimately results in bearing failure.
