[ "A study published in Science, by researchers at Rothamsted Research (an institute of the BBSRC), the Met Office, the Natural Resources Institute, and the Universities of Exeter, Greenwich and York, sheds new light on the flight behaviours that enable insects to undertake long-distance migrations, and highlights the remarkable abilities of these insect migrants.", "\n\nMany insects avoid cold British winters by migrating south in autumn to over-wintering sites around the Mediterranean. ", "Migrant insects then return to the UK in spring. ", "How such small insects undertake journeys of several thousands of kilometres has long fascinated scientists.", "\n\nThe reported study was funded by BBSRC and used two sets of specially-designed radar equipment to observe migrating butterflies and moths flying several hundreds of metres above the ground, and to describe the sophisticated flight behaviours that they have evolved. ", "These insect migrants have a compass sense that enables them to select winds which will take them in their chosen direction, and to travel at speeds of up to 100 km per hour. ", "The fast speeds of winds aloft mean that insects travel more-or-less downwind, but they make subtle adjustments to their headings so that they partially correct for wind-induced drift away from their preferred direction of travel.", "\n\nDr Chapman said \"Migratory butterflies and moths have evolved an amazing capacity to use favourable tailwinds. ", "By flying at the heights where the wind currents are fastest, migratory moths can travel between their summer and winter grounds in just a few nights.\"", "\n\nDr Hill said \"We estimate that over 2 billion insects were involved in the mass migration events that we studied. ", "These insect migrants are clearly very successful.\"", "\n\nThe study used a computer model dubbed \"NAME\" to demonstrate that the flight behaviours observed result in migrants travelling nearly twice as far and closer to their preferred direction as an insect just randomly drifting downwind. ", "Many migratory insects are pests of agricultural crops, so the model will be useful for predicting migration events in the future.", "\n\nMs Burgin said \"We combined the results from the radar measurements of moth flight with the outputs of a model of atmosphere motion to show that by hitchhiking on suitable winds, insects can travel at greater speeds than many migrating birds, which is important given the short lifespan of insects.\"", "\n\nThis study illustrates how insects successfully undertake long-distance migrations in favourable directions. ", "Climate change is likely to significantly alter the frequency of insect migrants, including introducing some agricultural pests that are completely new to the UK. ", "Thus, a better understanding of their migration strategies is increasingly crucial in helping to secure food supplies in the long term." ]

[ "The other day, tri-ace came up as a topic of discussion on a forum I visit, and I was forced to face some unfortunate realities about what once might have been my favorite developer. ", "Creator of the Star Ocean and Valkyrie Profile franchises, tri-ace played a large role in my gaming as a child--Star Ocean 2: The Second Story and Star Ocean 3: Till the End of Time stick out far more in my memories than any non-Final Fantasy, so to a preteen/teenaged version of me, tri-ace was more important than Squaresoft.", "So when The Last Hope offered some of the most annoying J-RPG stereotyped characters I'd ever wasted my time playing, to say that I was frustrated was putting it mildly. ", "For Star Ocean 5, I had my hopes high--I couldn't believe the franchise was coming back at all, but I felt confident they would be able to right all the mistakes of 4 and bring the series back to the minor level of prominence it had during the PS1/PS2 era. ", "I followed the character reveals and videos closely and everythingon track, and yet...something happened. ", "The game came out to barely mediocre reviews; filled with backtracking, a battle system so \"reminiscent\" of SO3's it was basically a clone, and a far too short main story for a game that already reused only a handful of environments, it seemed as if Star Ocean 5 had killed tri-ace's chances at being a console game developer for good.", "But was that athing? ", "As fans we often decry the loss of every single developer that shutters its doors or turns to the far more profitable mobile world but sometimes its a necessary decision. ", "Especially lately, as developers continue to pop up that make an already competitive market even moreso. ", "Let's take a break from talking about tri-ace for a second to look at some other small developers (and one large developer with a \"small\" game)so you can see what I meanis a mid-tier sized developer that's known for their deep, innovative battle systems and quick turnover times while developing titles on shoestring budgets. ", "They're a bit mercenary in how they get their funding, so what usually holds them back is a lack of proper development time even in the face of their ability to rapidly complete titles, as seen in their Legend of Korra and TMNT projects. ", "But most recently, the company released Nier: Automata alongside famed creator Yoko Taro to worldwide critical acclaim and fantastic sales for a project of that size. ", "This was able to happen because they combined a development team known for their superb gameplay with an auteur creator like Taro who was able to provide a world and characters with which players would want to get involved.", "Then you have Nihon Falcom, a tiny but venerated studio that's been around for nearly four decades. ", "Currently known for their Ys and Kiseki series, Falcom doesn't necessarily have great sales worldwide, but they do very well domestically. ", "Their games aren't graphically impressive (their first PS4 Kiseki looks like a late game PS3 title) and their stories aren't genius, but their worlds and lore just might be the most well-developed in gaming, anywhere. ", "Pages upon pages of text devoted to their history and relations between different countries, minor and major NPCs that have their own mini-stories that play out while you're in their cities. ", "They replace the need to dazzle with visuals or do unique innovations with a world that you can lose dozens of hours exploring and learning about.", "Finally, there's Bandai-Namco's Tales series. ", "To be clear, Bandai-Namco is bya small company--they're about as big as a Japanese developer can get, in fact. ", "And the Tales series has basically shifted into being a third pillar of sorts for J-RPGs between Square-Enix's Final Fantasy and Dragon Quest. ", "Still, I don't think many people would say that the budget for Tales titles would rival a Final Fantasy or probably even a DQ. ", "They're mid-tier, polished fantasy J-RPGs with an anime aesthetic that usually have good battle systems and decent production values.....Which brings me back to tri-ace, because at this point the Tales franchise have become \"Star Ocean, but better\". ", "And that's the developer's problem: there's not a single thingdo that's better than what's already on the market, or even especially different in an appreciable way. ", "They'd be almost be better off sticking to the decent amount of success they're experiencing on mobile. ", "But of course you're not here for that, so let's talk about what some backseat developer thinks they can do to save themselves.think Star Ocean is their best bet at standing out as a developer going forward. ", "But it would need to be a full-blown reboot, and preferably as the game people always think of when you say Star Ocean, not what it's always been. ", "Because hearing the name, most people would think: \"oh, a J-RPG about exploring space\" only to discover that it's a J-RPG that merelyabout space but more often than not ends up set on a planet that's more about high fantasy and magic tropes. ", "And just like that, all the intrigue of the game is usually taken out.", "A reboot of Star Ocean could instead take a hard sci-fi turn. ", "Allow players to traverse the galaxy, see multiple planets and meet dozens of alien races. ", "Perhaps the game steals liberally from Suikoden, and sets you in a world where you have to deal with the possibility of an interstellar war between multiple factions, and the only thing standing in its way is the crew you assemble from across the stars. ", "Along those lines, perhaps introduce a spaceship combat system...and have your ships develop more based on how many crew members you've assembled, as well as offering the ability to customize or purchase new ships a la Infinite Space. ", "Embrace the space opera and science fiction that's always been there but scarcely ever been lived up to. ", "This is the type of game that literallyin the Japanese console game space, roleplaying or otherwise, and it's exactly the kind of thing that would help tri-ace reassert itself as a developer worth mention in the HD era.", "Of course, budget is still an issue but after a solid decade of playing great games that aren't the best lookers, I think RPG fans will be okay if a potentially classic Star Ocean game isn't the prettiest boy/girl at the dance. ", "If anything, if that allows the game to be more full-featured and well-rounded of an experience, all the better.", "Ultimately, what's standing in tri-ace's way is the leadership necessary to carve out a niche of their own in the gaming world. ", "The console gaming industry is harsh, almost cutthroat in how demanding it can be of developers. ", "Since most developers can't do one thing at an A+ tier, gamers have come to settle for games that do most or all things at a B+ tier, and that's a tall order if you don't have the size and money behind you to make it happen. ", "And if you fail, there's usually nothing left for you than to close down. ", "Which is why as much as I want tri-ace to be as important a console developer as were did in my youth, I'm alright if they enjoy the \"easy\" money of mobile for awhile until they get there." ]

[ "Frictional unemployment\n\nFrictional unemployment is a type of unemployment. ", "It is sometimes called search unemployment and can be based on the circumstances of the individual. ", "It is time spent between jobs when a worker is searching for a job or transferring from one job to another. ", "Frictional unemployment is one of the three broad categories of unemployment, the others being structural unemployment and cyclical unemployment. ", "A person may be looking for a job change for better opportunities, services, salary and wages, or because of dissatisfaction with the previous job. ", "Strikes by trade unions also give rise to frictional unemployment.", "\n\nAnalysis\nFrictional unemployment exists because both jobs and workers are heterogeneous, and a mismatch can result between the characteristics of supply and demand. ", "Such a mismatch can be related to skills, payment, worktime, location, attitude, taste, and a multitude of other factors. ", "New entrants (such as graduating students) and re-entrants (such as former homemakers) can also suffer a spell of frictional unemployment. ", "Workers as well as employers accept a certain level of imperfection, risk or compromise, but usually not right away; they will invest some time and effort to find a match. ", "This is in fact beneficial to the economy since it results in a better allocation of resources. ", "However, if the search takes too long and mismatches are too frequent, the economy suffers, since some work will not get done. ", "Therefore, governments will seek ways to reduce unnecessary frictional unemployment.", "\n\nFrictional unemployment is related to and compatible with the concept of full employment. ", "At full employment the unemployment rate will be positive because of the inevitable presence of frictional unemployment.", "\n\nThe frictions in the labor market are sometimes illustrated graphically with a Beveridge curve, a downward-sloping, convex curve that shows a fixed relationship between the unemployment rate on one axis and the vacancy rate on the other. ", "Changes in the supply of or demand for labor cause movements along this curve. ", "An increase in labor market frictions will shift the curve outwards.", "\n\nExamples\nOne kind of frictional unemployment is called wait unemployment: it refers to the effects of the existence of some sectors where employed workers are paid more than the market-clearing equilibrium wage. ", "Not only does this restrict the amount of employment in the high-wage sector, but it attracts workers from other sectors who wait to try to get jobs there. ", "The main problem with this theory is that such workers will likely \"wait\" while having jobs, so that they are not counted as unemployed. ", "In Hollywood, for example, those who are waiting for acting jobs also wait on tables in restaurants for pay (while acting in \"Equity Waiver\" plays at night for no pay).

", "There has been a strong current of contemporary illustrators taking on the challenge of illustrating tarot cards in the last few years and the results are, for the most part, stunning, the variety of interpretations brings a wonderful, modern vibrancy to the tarot, always a reminder that it is a useful tool even outside the realm of diviniation. ", "While not all of these decks are easy or useful to read with the sheer imagination that many of the artists bring to a single illustration is worth checking them out. ", "Often the ability to draw a single card instead of an entire deck can produce beautiful results.", "\n\nThis is probably the first contemporary illustrated tarot I ever saw. ", "While I was already working on the Chibi Tarot the existence and expansion of a modern illustrated tarot really heartened me. ", "The cards themselves are from a mind-bending variety of styles. ", "The sheer ecclectism of the deck makes it a wonderful artifact, but I can’t imagine reading with it. ", "The Super Punch tarot was produced for an art show at the Bear and Bird gallery in Florida, but was never produced as an actual deck since the variety of sizes and styles made that nearly impossible. ", "I actually own one of the pieces that was in the show, Jerrod Maruyama’s 6 of Cups, for what I hope are obvious reasons.", "\n\nThe Light Grey Tarot was “[c]urated by Light Grey Art Lab as a part of the Tarot, Mystics and Occult Exhibition.” ", "This deck brings together a group of 78 artists to reinterperet the tarot in a much more cohesive fashion than the Super Punch tarot did. ", "While the styles still vary wildly, there seems to be more focus on the conjuration of the occult. ", "Where the Super Punch illustrators seemed to bring tarot ideas into the realm of pop culture (the King of Cups, for example), the illustrators in the Light Grey Tarot seemed much more focused on bringing a powerful syncretic and mystical energy into the deck. ", "So while the the illustrations feel fresh and lively, the connection to the tarot’s rich history of symbolism and illustration shines through here.", "\n\nIt was produced as an actual deck with a booklet and is one that I own and have read with. ", "It is not the most resonant deck for me, as not all the illustrations seem to be focused on the symbolism of the cards (the six of swords is particularly mute for me), but so many of the illustrations are so evocative that reading with it can be a real pleasure, and the deck is still for sale.", "\n\nAn oversized majors only deck funded on Kickstarter, the Wooden Tarot is the work of Andy Swartz, who’s style “is typified by dream-like, faintly creepy and macabre fantasy wildlife.” ", "The deck is a work of art on every level, beautifully designed, illustrated and executed. ", "The wooden part of the tarot stems from her canvasses: 6×8″ wooden panels painted on with a mixed media of acrylic paints and colored pencils.", "The illustrations are simultaneously delicate and lush, capturing the rich color of animals, plants and minerals she depicts with lovely accuracy while simultaneously conveying the mystical allure of the shadows flickering just beyond the edge of the firelight.", "\n\nThe Wooden Tarot major arcana is completely sold out, but Andy completed another Kickstarter in March of this year and is currently producing a full 78 card deck, which you can preorder here. ", "The Minor Arcana carries over both the beauty and the sparse style of her artwork, while adding and interesting new organic layer to the deck by renaming the suits Bones, Plumes, Stones and Blooms.", "\n\nThere’s no question that traditional tarot decks carry with them a boatload of white male privilege. ", "For starters, there’s the court that reinforces medieval gender roles and power disparities. ", "Then there’s the decks themselves: despite being illustrated by powerfully talented women, Pamela “Pixie” Smith and Lady Frieda Harris, the two most influential tarot decks of the last 100 years are both more familiar to the public by the names of their male “creators”: The Rider Waite deck and Crowley’s Thoth Tarot. ", "The Collective Tarot addresses much of this cis-gendered white male privilege through their radical revisioning of the tarot. ", "Describing itself as “a collaboratively created, radically-politicked, queerly-revisioned Tarot deck” the Collective Tarot is an extreme departure from the traditional western occult symbols embodied in the tarot to the point that it becomes nearly unrecognizable, which may well be the point.", "\n\nThe pieces themselves are intense and raw. ", "There is an unfinished quality to the art, an intentional crudeness reminiscent of punk show flyers and ‘zine covers. ", "The aesthetic reinvigorates the art in a modern, urban way queering the traditional occult symbolism in ways that I often find offensive, which I think is the point: taking the sacred and profaning it, not simply for the sake of profaning it but to stretch it in ways that it certainly never envisioned for itself in order to include those it never attempted to envision. ", "In doing so the Collective Tarot has created something less like a tarot deck and more like its own unique oracle. ", "While it adheres to the traditional structure of five suits with 78 cards with many cards that overlap with traditional tarot trumps I find it more fruitful to approach this deck from a completely fresh perspective rather than attempting to find similarities between what I’ve known and what they’ve created.", "\n\nWithout question the Pictarot is the least occult of the decks listed here. ", "Created and published by PictoPlasma, a German/New York based organization focused on the development and promotion of character design, that’s exactly what this deck promotes: characters. ", "While there is carry over and dialogue between the characters and the ideas that they represent the focus here is clearly on the development of the character at the expense of the idea. ", "None of the cards have any background or environment to support or complicate them, the figures are the complete focus of attention. ", "Still, the characters are inventive, creative and entertaining and character design is a big part of why I love the tarot, so I am personally enchanted by this deck, which you can still buy online.", "\n\nAs an added bonus, if you’re not ready to commit to the deck without seeing all the cards (and you have an iOS device) you can check out the entire deck through the Pictarot app. ", "Heavy on the theatre, and without much flexibility about how you use the cards (they have a one, two, four and seven card spreads) the app is just $.99 at the app store and can be an amusing way to pass 30 minutes without actually breaking out your cards.", "\n\nThe Ostara Tarot is the most recent member of this group. ", "I recently stumbled across is on the reddit pagan forum. ", "The product of four artists working together, the results thus far vary stylistically, but are united by a desire to explore the spirituality and the mysticism of the cards themselves and the deck as a whole. ", "The deck is strongly nature based, but speaks to the human intersections with nature, especially the power of making and artifacts, drawing out the intricacy and beauty of the crafted object and the way that it can interact with the natural world, as well as the way the natural world is transformed into artifacts as a raw material for human expression.", "\n\nThe level of mysticism ranges a spectrum across the artists’ styles, from the psychedelic dreamscapes of Julia Iredale whose smoky-colored branch-pierced snakes echo strains of a voodoo saint Sebastian, to Molly Applejohn whose adorably anthropomorphic animals are deeply reminiscent of Brian Jacques’ Redwall and David Peterson’s MouseGuard.", "\n\nAs of this writing there are 20 cards available. ", "I’ll be following up this post with an interview with artist Molly Applejohn who will hopefully provide more detail about the plans for the deck and whether they’d on publishing or not.", "\n\nWhat are some of your favorite contemporary decks?

", "To suggest that he’s the icon for a sinister hate movement is obviously more than ludicrous; it’s yet another example of the liberal media imposing meaning onto symbols which are many things to many people.", "\n\nThe idea that ‘Pepe is a neo-nazi symbol’ is the same as saying ‘the confederate flag is a symbol of oppression’ or ‘all six-pointed stars are anti-semitic’.

", "The use of Pepe by the Trump camp is indeed a signal though, and a very obvious one at that: the omnipresence of this cartoon frog among their most vocal supporters is not lost on them, and by incorporating him into their imagery they are effectively saying “we get it, we understand internet meme culture”, something which can not be said for the Democratic frontrunner.", "\n\nA recent poll by CNN, showing Hillary leading by 9 points, conveniently omitted voters aged between 18-34 from their sample, a revealing insight that perhaps Clinton’s ‘millennial outreach’ has been less than stellar.

", "Similar to the 1950s tirades against rock and roll as being ‘the devil’s music’, Hillary has shown the extent to which she is out of touch with pop culture as a whole, and in this new frontier of political discourse the perception of ‘Old Lady Clinton’ as being out of the loop cannot be un-memed.", "\n\nThe fact that Hillary’s PR team, by all accounts a seasoned band of provocateurs, would post the message shown above – on Hillary’s official website no less – shows the extent to which they’ve completely lost control of the narrative. ", "Hillary’s evident health issues, previously derided as ‘baseless conspiracies’, have since been covered at length by the mainstream media.

", "For one, it’s clear evidence that Hillary’s campaign is in full defensive mode with regards to its online presence; Hillary’s official Twitter posts are flooded with more frogs than the old testament, and her ‘online team’ of Correct the Record shysters have yet to make even the slightest dent in the collective consciousness. ", "Predictably, Hillary’s public statement against Pepe has been met with widespread hilarity from all corners of the internet, and I’m sure that if there was an algorithm that tracked the amount of frogposting over time (F/t), one would see a marked increase on social media since her statement was first issued.", "\n\nSimilar to the everyman’s adoption of the ‘deplorable’ moniker after her previous outburst colloquially known as BasketGate, the mainstreaming of Pepe is now complete, and everyone is now in on the joke – everyone except the woman running for President, unfortunately.
