Restrictions against beginning a sentence with and or but are based on shaky grammatical foundations some of the most influential writers in the language have been happily ignoring such restrictions for centuries.* Over-used, beginning a sentence with a conjunction can be distracting, but the device can add a refreshing dash to a sentence and speed the narrative flow of your text. But often the initial conjunction calls attention to the sentence in an effective way, and that's just what you want. Isn't the conjunction at the beginning of the sentence a sign that the sentence should have been connected to the prior sentence? Well, sometimes, yes. However, the question whether one can begin a sentence with a small conjunction often arises. The use of the little conjunctions especially and and but comes naturally for most writers. Transitional tags run the gamut from the most simple the little conjunctions: and, but, nor, for, yet, or, (and sometimes) so to more complex signals that ideas are somehow connected the conjunctive adverbs and transitional expressions such as however, moreover, nevertheless, on the other hand.įor additional information on conjunctions, click HERE. There are four basic mechanical considerations in providing transitions between ideas: using transitional expressions, repeating key words and phrases, using pronoun reference, and using parallel form. You might be able to leap from one side of the stream to the other believe that your readers need some stepping stones and be sure to place them in readily accessible and visible spots. In fact, it's a good idea to assume not only that your readers need all the information that you have and need to know how you arrived at the point you're at, but also that they are not quite as quick as you are. You must never assume that your readers know what you know. Providing transitions between ideas is largely a matter of attitude. Unless readers can move easily from one thought to another, they will surely find something else to read or turn on the television. The most convincing ideas in the world, expressed in the most beautiful sentences, will move no one unless those ideas are properly connected.

The top two US manufacturers, for example, can produce 280 million vials per year, capable of holding up to 2.8 billion doses. Early indications suggest that there is sufficient global manufacturing capacity for syringes and fill-finish materials. Scaling access to material inputs and boosting production levels can cause logistical, contractual, and even diplomatic challenges, requiring new forms of collaboration. Raw-materials constraints in production scaling In a later section, we outline possible approaches to mitigating each of these risks, with practical steps for organizations that have a role in vaccine deployment. From this model, we have highlighted six possible areas of risk to the rapid delivery of COVID-19 vaccines in the United States and elsewhere. The common operating model provides the details of end-to-end vaccine deployment. Much needs to be done for the promise of COVID-19 vaccines to become a reality. A realistic risk assessment of vaccine deployment is needed, because future success cannot be taken for granted. An array of complex challenges are still before us, as production is ramped up and rollouts are planned and executed. Their often-heroic efforts give cause for hope. Scientists, doctors, other healthcare workers, clinical-trial participants, and regulators have been working intensely to develop, distribute, and administer the vaccines that will help end this pandemic. Cumulatively, between 2.4 and 3.4 times as many doses (mainly because of the double-dose requirement) will be needed as are used for the annual flu vaccinations (exhibit). In the United States and other countries with sufficient vaccine quantities and adoption, herd immunity by October 2021 is conceivable, but for that to happen, more than twice as many doses of COVID-19 vaccines will have to be administered each month as were administered during the 2009 H1N1 flu vaccine drive. A further issue is vaccine skepticism, affecting a certain segment of all populations, including the United States. Historical wariness of interacting with authorities can also be a barrier. To arrive at the postpandemic era, vast numbers of dedicated individuals will need to continue working intensely in the months and years ahead.Īt the receiving end, vulnerable populations-especially in developing countries-could face added hurdles, including difficulty in reaching administrative sites, getting time off from work to receive doses, and arranging childcare for the same. Tens of thousands of transporters, vaccine handlers, medical and pharmacy staff, and frontline workers have required training on the specific characteristics of each manufacturer’s distinct vaccines. Massive volumes handled, distributed, and stored through cold chains must adhere to safety regulations. Suppliers, manufacturers, and regulators are collaborating to ramp up production of vaccines. In the United States alone, hundreds of organizations play a role in vaccine deployment, adapting their operations to meet demands for volume, speed, and better technology. A breakdown at any point in the deployment process can set off a cascade, shutting down the entire system. Essentially, the interactive is a qualitative risk map, showing the many stages of vaccine deployment and highlighting areas of potential failure as one party interacts with another. In this article, we consider elements of this enormous undertaking, the risks that are inherent, and potential means of further accelerating vaccination.Ī common operating model of COVID-19-vaccine delivery, shown in the interactive, demonstrates the complexity of the task at hand. To arrive at the postpandemic era, in which populations experience herd immunity, vast numbers of dedicated individuals will need to continue working intensely in the months and years ahead. The epidemiological end to the COVID-19 pandemic seemed like an optimistic dream a few short months ago, but, with the development, approval, and rollout of several vaccines, it is now practically realizable in much of the world. Nonetheless, experts have expressed confidence that safe and highly efficacious vaccines are reaching the market, and we are beginning to see “the light at the end of the tunnel” of this devastating pandemic. In certain places, the COVID-19-vaccine effort has hit a few speed bumps stockpiles have accumulated, and deployment to vulnerable countries and at-risk groups has been slower than expected. This article was a collaborative effort by the global Risk Practice and authors from across the firm, including Gaurav Agrawal, Tara Azimi, Jennifer Heller, Pooja Kumar, Mihir Mysore, Parag Patel, Adam Sabow, Shubham Singhal, and Joseph Truesdale. If you’re a diehard Disney fan in the mood for a short, breezy platformer, this may hit the spot.

It captures the original's unique style while expanding on it in a meaningful way, without burdening the experience with unnecessary additions or other concessions to the Disney license. Length and occasional control issues aside, Castle of Illusion is a very successful remake. If the jumping was tightened up a bit, and the difficulty spikes not so big then this could have been one of the best platformers of recent memory. It will cost £9.99/ €14.99/ $ 14.99 and can be completed in about four hours, though there is some replay value if you want to get the collectibles.

In a word, lots In many ways, this feels like the product we should have built from the beginning. Moving from euphoria to audacity, Byrne leads a version of Janelle Monáe’s “Hell You Talmbout,” with the band chanting the names of African-Americans killed by police, that Lee visualizes with oracular power. The film is studded with numbers that take your breath away: the impassioned suburban camp nostalgia of “Don’t Worry About the Government,” an “I Zimbra” that’s never sounded this recklessly good, the Warholian swoon of “I Should Watch TV,” the let’s-party-on-with-social-anxiety-disorder of “Everybody’s Coming to My House,” and an exultant “Once in a Lifetime” (a song so sublime it’s like therapy) in which the image of Byrne leaning back, the life force rushing over him, as he goes into the “Time isn’t holding us” refrain has to be one of the most ecstatic gestures I’ve ever seen in a pop-music film. Annie-B Parson’s choreography is so ingeniously alive that you almost feel like Byrne and the others are making up their casually synced funk-soul movements on the spot. Yet taken together, the music in “American Utopia” achieves a cumulative rush of Heady effervescence. It must be said: The numbers from Byrne’s solo albums can’t quite match the kicky panache of the songs from the Talking Heads era. The new movie builds and crests and surges, the flow of music interrupted only by the cheeky sincerity of Byrne’s stand-up-comedy stage patter (“Meeting people is hard! I know, I know: We have to do it”). The musicians come on a few at a time, and in many ways “American Utopia” feels like “Stop Making Sense 2020.” It’s a concert film gone digital, without the wires. Now, in his floppy white hair and life-size suit, still handsome and sleek but looking, at times, like a hipster Gore Vidal, he’s the aging rock star as sage, old and wise enough to let his inner spirit burst through. In “Stop Making Sense,” Byrne, with his dark hair and popping eyes, presented himself as a stylized vision of a man in a Big Suit floating between how-did-I-get-here? confusion and burning-down-the-house liberation. “American Utopia” is a show designed to heal those disconnections. But he’s really talking about something that links up with time-honored Byrne-ian obsessions - the loss of soul (and maybe mind) bred by the fake reality of middle-class consumerism, and the detachment he feels from his fellow humans. Growing up, Byrne tells us, is about losing neurons as we get whittled down to the identities we are. That brain, by the way, is Byrne’s prop partner for “Here,” a song about the brain (“Here is an area that needs attention,/Here is a connection with the opposite side…”), which he uses to introduce the observation that babies’ brains have more neurons than those of adults. “It’s just us, and you,” says Byrne, speaking to the audience, and the movie nudges that “you” into a place beyond the fourth wall. But in “American Utopia,” Lee turns the stage into a diorama he keeps breaking apart and pushing back together. He shoots the show from a dizzying array of angles: head-on, looking down from the ceiling (the film opens with an overhead shot of Byrne seated at a table, staring at a plastic brain), and gazing up at the performers, so that we feel as if we’re inhabiting the space around them.Īny screen version of a Broadway show will take you closer to the action than most theater seats do. Lee extends that sensation with his giddy camera placement and close-up views of the musicians reveling in the cool joy of what they’re doing. Most of them carry wirelessly amplified instruments (a snare drum, a guitar, a digital piano), so they can stroll around the stage in a technologically liberated state of frictionless freedom. In “American Utopia,” the singer-musicians aren’t tethered to amplifiers or drum sets or big chunky keyboards. A handful of the numbers came from Byrne’s 2018 album “American Utopia,” but close to half of them were Talking Heads songs, most of which were featured 30 years ago in “Stop Making Sense,” Jonathan Demme’s epochal Heads concert movie. 20, 2019, consisted of the former Talking Head and 11 fellow musicians, all barefoot and dressed in silver-blue suits (a look that seemed inspired, on some karmic rock haberdashery level, by the image of Paul McCartney on the cover of “Abbey Road”), dancing and marching and prancing and bopping around a bare stage as they performed 21 songs. But Spike Lee’s playful and entrancing big-screen version of David Byrne’s “ American Utopia” is better than the next best thing - it feels more like a whole new thing.īyrne’s spiky and exuberant 21st-century rock-concert-on-Broadway jamboree, which opened at New York’s Hudson Theatre on Oct. When you watch the filmed version of a show like “Hamilton” or “Springsteen on Broadway,” it can feel like the next best thing to being there. Notch activity strongly impacts the morphology of both developing and postmitotic neurons. Dendrite morphology is regarded as a phenotypic property that can be drastically altered by extrinsic factors such as activation of the Notch receptor and neurotrophins ( Whitford et al., 2002 Salama-Cohen et al., 2005 Salazar et al., 2020). These morphological changes constitute the cellular and molecular bases of the so-called neuronal plasticity. For this, modification of the cell morphology is required (regarding the number of dendrites, length, branching, and synaptic input) in order to establish new connections. Proneural signaling is activated during development under physiological conditions and reactivated in the adult organism to repair damage in case of injury. Neurons are polarized cells both structurally and functionally. Our results show that the Estradiol/BDNF/TrkB/Kif21B/Ngn3 is a new and essential pathway mediating hippocampal neuron development. In addition, Kif21B silencing also decreases Ngn3 expression, and downregulation of Ngn3 blocks the effect of BDNF on neuron morphology.ĭiscussion: These results suggest that Kif21B is required for the effects of estradiol and BDNF on neuronal morphology, but phosphorylation-mediated activation of TrkB is essential only for axonal growth. Notably, the downregulation of Kif21B abolishes the actions of estradiol and BDNF in both the axon and dendrites. Combined with estradiol or BDNF, it blocks their effects on axons but not dendrites. Treatment with K252a, a TrkB inhibitor, decreases dendrite branching without affecting axonal length, whereas. Results: We show that estradiol treatment increases BDNF expression, and estradiol and BDNF modify neuron morphology through TrkB signaling. Methods: In the present study, we assessed the involvement of kinesin Kif21B in the estradiol-dependent signaling mechanisms to regulate neuritogenesis through cultured mouse hippocampal neurons. On the other hand, Kif21B regulates microtubule dynamics and carries out retrograde transport of the TrkB/brain-derived neurotrophic factor (BDNF) complex, essential for neuronal development. For instance, the developmental actions of estradiol on hippocampal neurons are well characterized, and we have demonstrated in previous studies that Ngn3 mediates these actions. Extracellular factors strongly influence neuronal shape and connectivity. Introduction: Neurons are polarized cells, and their ability to change their morphology has a functional implication in the development and plasticity of the nervous system in order to establish new connections. 4Department of Anatomy, Histology and Neuroscience, Autonoma University of Madrid, Madrid, Spain.3Servicio de Proteómica, Instituto Biosanitario de Granada-IBS, Fundación Para la Investigación Biosanitaria de Andalucía Oriental-Alejandro Otero (FIBAO), Antiguo Hospital Universitario San Cecilio, Unidad de Apoyo a la Investigación (UNAI), Granada, Spain.2Centro de Investigación Biomédica en Red de Fragilidad y Envejecimiento Saludable (CIBERFES), Instituto de Salud Carlos III, Madrid, Spain.1Instituto Cajal (IC), CSIC, Madrid, Spain.Danny Ganchala 1 Daniel Pinto-Benito 1,2 Elisa Baides 1 Isabel Ruiz-Palmero 2,3 Daniela Grassi 1,4 Maria Angeles Arevalo 1,2 * |
