This figure shows how workers' effort varies with the shutdown probability of firms and the amount of government unemployment benefits. The darker the color, the higher the effort level. First, when the shutdown probability changes from 0 to 1, it indicates that there are fewer vacancies in the labor market and that workers are more likely to face unemployment. Because of this uncertainty, workers are demotivated, leading to a decrease in effort. In addition, when the government grants larger amounts of unemployment benefits, firms will offer higher wages to workers to ensure an adequate labor supply. According to reciprocity theory, workers will reward firms’ generous offerings with higher effort. While my project examines the effect of government unemployment benefit programs on the long-term relationship between workers and firms, this figure analyzes one of the scenarios, namely how this effect changes when firms face an uncertain risk of collapse.

Glasgow - another pinhole effort. Not as tight on the framing as I'd hoped but not bad given the lack of viewfinder....
Ok, so I've submitted this to the PCA group under Leading Lines. I'd hoped to get out to take something specifically for the assignment but with one thing and another (and me getting my dates wrong) I just haven't been able to. I did take one on friday but the film's not back yet.... This shot was taken in the timeframe and when I took it I was definitely trying to make use of the steel structure in the foreground as a leading line, so I guess it qualifies, despite me not knowing about the assignment at the time!

Somewhere around a 4 minute exposure
I've been enjoying messing around with the pinhole over the last couple of weeks but haven't really tried much in colour till now and I've not got my head around the colour shifts from the long exposures. or the reciprocity failure for the colour film yet (conflicting info online, so I'm just guessing).
This is also the first time I've tried a strong foreground interest so close to the camera. Accurate framing with no viewfinder of any sort is, well... trickier than I thought! I've framed this slightly lower than I hoped. The other thing I'm finding with the pinhole is that it's changed the way I compose when I use it: with such a strong vignette and such heavy blur as you move from the centre of the shot, the standard rule of thirds has gone out the window.
The white dot in the sky is the moon, which looked rather more impressive when I was there!
It was raining all day long, but it was the day I got my hands on Makina, so I had to go out and make at least a shot.
After all the fiddling with meter, tripod, camera and umbrella (this one, being of course, by far the worst of them) this is what I came out with.
That is if I don't count The True First Makina Shot - the inner side of 62mm lens cap.
The meter said 8s for f/4.5 metered incident on the bench. I exposed 25s because reciprocity. A tad too much...

The much larger aperture available - compared to the kit zoom lens I normally use - enabled a faster shutter, a lower (less "noisy") ISO, and also a shallower depth of field.
The lighting colour was often a terrible mix of direct sunshine, blue sky and the very orange colour reflected from wooden table tops. The "colour balance" adjustment tool in a photo editor editor - selectively adjusting highlight, mid-tone and shadow colours was useful in reducing the effects of the sometimes very blue shadows. (Traditionally this type of tool is used to "fix" issues relating to colour film, where the colour of light and dark areas could vary. This is for lots of reasons for relating to the processing and chemistry of film; and also to the physics of photons exposing film grains - for example reciprocity failure en.wikipedia.org/wiki/Reciprocity_(photography) where darker areas for each of the colours present in the shadows may not be recorded proportionately. Presenting the same images in Black and White is another way of "dealing with" [avoiding!] the issue.

Friend Who? :-D
The story so far:
First party, hereinafter referred to as "friend", held posession of a good, hereinafter "motorcycle". Second party, hereinafter "buyer", desired said good and entered in an agreement with the first party. First party left for Canada, causing this agreement to go unfulfilled.
Today third party, hereinafter "lucky us", engaged in dealings with the second party pursuant to the fulfillment of this agreement. Documents were transferred and filed and, in just reciprocity, custody of legal tender was transmitted from second party to third party. See Exhibit A above.
Third party are now weighing their options :-)

この研究プロジェクトはバイオミメティクスの観点をベースに、自然の形態システム（モーフォロジー）をアルゴリズムにより再現し、環境性能の高い建築を生成する方法を探求している。自然界の中で高い換気性能をもつシロアリ塚を参照し、そのモーフォロジーが流線形の外形と内部の導管のブランチング・システムの組み合わせとして解釈されている。さらにこのモーフォロジーをデジタルに再現構成するアルゴリズムと、このアルゴリズムをエンジンとするパラメトリック・デザインと流体解析シミュレーションをループさせたデザイン・プロセスが新たに開発された。この統合的デザイン・プロセスは、環境の外的条件とその建築形態による内的な環境性能を有機的に関係させ、建築を自然環境に最適に適応するものとして生成することを可能にしている。
This project investigates a computational design methodology with reconstructions of natural morphologies through computational algorithms based on Biomimetics whereby higher-performative architecture can be generated. Termite mounds as a representative reference of the highest performative system in nature in terms of its natural ventilation are interpreted as the combination between the streamlining external form and internal branching systems of air conduits. Furthermore, a computational algorithm, which can reconstruct termite mounds' morphologies, and a new design process looping between parametric designs driven by the algorithms and C.F.D. simulations are developed. This integral design process can make architectural forms adaptive to nature through the reciprocity between external conditions from environments and internal performances of architecture itself.

He may not always sound like one, but his actions are in line with the GOP’s agenda.
MANDEL NGAN/AFP/GETTY IMAGES
WASHINGTON ― Donald Trump was supposed to be a different type of Republican. He’s frequently switched political parties, won over some traditionally Democratic voters and attacked well-regarded members of the GOP. Many establishment Republicans disavowed him, while others hoped his heterodox views ― antithetical to many pro-business elites ― could reshape politics.
But as president, Trump has mostly governed as a traditional Republican leader. His rhetoric may sound different, but his biggest accomplishments and policy initiatives are, at the end of the day, almost completely in line with an orthodox GOP agenda ― with more of an emphasis on nationalist policies.
Trump didn’t execute some hostile takeover of the party; he was readily welcomed by many in the rank and file as its chief, and his administration has already fulfilled many items on its wishlist.
“President Trump has absolutely governed as a Republican,” said Boris Epshteyn, a former Trump aide who is now chief political analyst at Sinclair Broadcast Group. “The president has had success on a wide range of fronts which are key to the Republican and conservative agenda, including deregulation, tax reform, decimating ISIS, repealing [Obamacare’s] individual mandate, reforming immigration, etc.”
“It is also important to note how involved the president has been in supporting Republican candidates throughout the country and working to keep GOP majorities in the House and the Senate,” he added.
The most significant accomplishments under Trump have as much to do with Congress as they do with the president. Legislatively, Trump’s biggest win was the tax cut law that delivered a massive permanent reduction for corporations. While Trump aides helped craft the legislation, it was something that congressional Republicans like House Speaker Paul Ryan (R-Wis.) have been preparing for years ― long before Trump ran for president.
In many ways Trump is governing as a traditional Reaganite – less government regulation, less taxes and a stronger military.
-Newsmax CEO Chris Ruddy
Trump also nominated Neil Gorsuch to the Supreme Court, ensuring that conservatives continue to hold the majority on the bench. But the reason Trump was able to choose a justice at all was thanks to Senate Majority Leader Mitch McConnell (R-Ky.), who refused to let the chamber vote on President Barack Obama’s nominee when Antonin Scalia’s death created a vacancy in early 2016.
And in filling the high court vacancy and others in lower federal courts, Trump has leaned heavily on recommendations from the Federalist Society, which has a deep network of conservative legal talent.
While Trump came in promising to “drain the swamp,” his lack of political experience has allowed the swamp to thrive. Lobbyists, special interest groups and even foreign nations have been able to find ways into the administration.
Trump initially appointed a number of outsiders to his cabinet and top staff. Recently, however, he has begun turning to Republican insiders and former GOP officials who are more ideologically aligned with the party establishment. Larry Kudlow, his new top economic adviser, is a long-time free trade and tax cut advocate. John Bolton, his new national security adviser, previously served as United Nations ambassador under President George W. Bush and is one of the most hawkish voices in American foreign policy who has fiercely defended the Iraq War.
A policy area where Trump has most radically broken with Republicans is on trade. Trump’s decision to impose tariffs on steel and aluminum, as well as additional steep tariffs on China, has spooked markets and sparked fears of an impending trade war.
While congressional Republicans have warned about the negative effects of Trump’s tariffs, few have indicated they will support legislation to nullify them. China, meanwhile, retaliated against the U.S. on Monday by imposing tariffs on 120 types of commodities, which is expected to primarily affect American farmers.
“In many ways Trump is governing as a traditional Reaganite ― less government regulation, less taxes and a stronger military,” Trump confidante and Newsmax CEO Chris Ruddy said. “Even on trade, Reagan was a hawk and Trump tapped his key trade [representative], Bob Lightizer. Trump often stakes out positions more extreme than Reagan, but observers should see this as a negotiating tactic for him. With Trump, always look at results and the bottom line; they tend to be quite reasonable and good.”
Former House Speaker Newt Gingrich (R-Ga.) agreed with the Reagan comparison, but said Trump put more emphasis on “things that have changed.”
“I think he would approve of Trump’s nationalism about controlling immigration and focusing on merit based immigrants,” Gingrich said. “Reagan had defense, economic growth and the deficit in that order and the recent Trump signature of the spending bill followed the Reagan pattern. Trump’s aggressive trade policy would have been understandable to Reagan because the world has changed. When the director of national intelligence in 2015 said China had stolen $460 billion in intellectual property in one year you clearly have to rethink your trader policies.”
The George W. Bush wing of the party, in contrast, was “more globalist and more anti-deficit.”
MARK WILSON/GETTY IMAGES. Trump recently chose former United Nations Ambassador John Bolton (left), as his new national security adviser. He’ll work closely with Defense Secretary Jim Mattis.
Trump often gives members of his party heartburn when he praises Russia and its president, Vladimir Putin. But he recently listened to his staff and agreed to expel 60 Russian spies and diplomats, the largest such expulsion in U.S. history. The move drew rare praise from lawmakers of both parties.
“This fits the pattern of our policy toward Russia in the Trump administration,” John Herbst, a Russia scholar at the Atlantic Council, told The Washington Post. “If you just look at policy, this administration has taken steps the Obama administration was not willing to, such as supplying antitank missiles to Ukraine. The president’s heart doesn’t seem to be in it, but for whatever reason, he’s willing to go along with his advisers.”
Immigration is perhaps the top issue that animates Trump’s base ― and therefore himself ― but he’s hardly the first GOP politician to use it to appeal to voters. During his 2010 re-election bid, for example, Sen. John McCain (R-Ariz.) starred in a memorable ad in which he walked along the U.S. border with Mexico and urged then-Sheriff Paul Babeu to “complete the danged fence.” In 2012, GOP presidential contender Mitt Romney urged undocumented immigrants to “self-deport.” And just last week, Romney said as a Senate candidate in Utah that undocumented immigrants who came into the country as children shouldn’t be allowed to obtain legal status at all.
Trump recently signed a $1.3 trillion government funding bill into law that will greatly increase the federal deficit by raising spending for domestic and military programs. During the Obama administration, Republicans railed against the federal deficit and called for cutting spending. But the fact that the omnibus sailed through was less a result of Trump being a new type of president then the reality that Republicans no longer need to make the deficit a political issue now that they have a GOP president.
On gun policy, Trump stunned lawmakers earlier this year when he publicly embraced several gun control measures and shot down GOP priorities like concealed carry reciprocity. He even, shockingly, said he would be fine taking away people’s guns without their permission, and told members of Congress that they should be willing to stand up to the National Rifle Association.
Shortly thereafter, however, order in Trump’s Washington was restored: The Republican president had realigned himself with conservative priorities and abandoned talk of pushing lawmakers to pass broader gun control proposals.
And on social policy, Trump has continued to restrict abortion access and block advancements for lesbian, gay, bisexual and transgender people, staying in the space where Republicans have traditionally fallen.
“On most of the issues, the policies of this administration have fallen under traditional Republican policy,” GOP strategist and former Republican National Committee spokesman Doug Heye said. “This is seen not only in the measures advanced by the administration … but also in the personnel that the administration has brought on board.”
“That’s why many who [were] critical of Trump in the campaign are now backing him to the hilt,” Heye added. “It’s also why members of Congress, many of whom are privately critical of the administration, are putting their heads down and focusing on their committee or subcommittee. They know that this may be their best opportunity to fulfill long-held policy goals.”

Roman copy of a Greek work of the 2nd century B.C.
These young girls, linked in a dance-like pose, represent The Three Graces: Aglaia (Beauty), Euphrosyne (Mirth), and Thalia (Abundance). They bestow what is most pleasurable and beneficent in nature and society: fertility and growth, beauty in the arts, harmonious reciprocity between men. They enjoyed venerable cults in Greece and Asia Minor. In mythology, they play an attendant role, gracing festivals and organizing dances. Their closest connection is with Aphrodite, whom they serve as handmaidens.
This carefully calculated, frieze-like composition is typical of classicizing art of the second and first centuries B.C. Instantly recognizable, it soon became the canonic formula for representing the Graces, who appeared in every medium and on every kind of object, from mirrors to sarcophagi.
This is from a series of still lifes that I shot on Monday. I'm doing some testing of my new Nikkor 300mm W lens and trying to get my view camera technique nailed down. These negatives got a little dark, but they're still printable. Next time I set up a still life like this, I won't do N+1 processing, I just develop normally. I had a 4 stop range when I metered, and wanted a 5 stop range, so I added 30% to my development times, but subtracted 20% for reciprocity compensation due to this being a long exposure. It's something new I learned: If you have to add exposure to correct for a film's reciprocity characteristics, you conversely have to decrease development so that you don't blow out the highlights. The end result was dark negatives.

Last visit to Chicago presented me with extremely warm days, so I opted to do some indoor photography instead of carrying the 8x10 in nearly 100 degree heat. Reciprocity failure of this film seems to be consistent with panchromatic films that I tend to use, which made calculating exposure a little easier.

Technical data: large format black and white film shot, f/22. natural light reading resulted in a 60 second exposure time after allowing for bellows extension and reciprocity failure. Ilford Delta 100 film, exposed at EI 50.
Window light was from camera left. Sunpak 333 flash unit positioned directly behind (and hidden by) the apples, fired toward the camera on 1/4 power. The flash was set to wide-angle zoom.
This was my first strobe usage with a large format camera, and I realized that my remote trigger transmitter was hot-shoe only, no PC connector. but since i had a 60 second exposure for the ambient light anyway, i just popped the flash by hand. My hand was in the shot for such a short time, it doesn't register.
But in the end, they're just apples.

© Avi Das | Reality So Subtle 4x5z pinhole camera in ultra-wide 35mm configuration, f/175 exposed for 4'20" (reciprocity adjusted).
My aunt and uncle own a small town newspaper that still uses a 24x24" process camera to shoot the layouts. I'm attempting to shoot portraits with this camera.
The above photo was taken with 12 sheets of 4x5" laid out in a grid on the camera's back. A wall bisects the camera and the back of the camera is its own darkroom, allowing me to work in total darkness. The back has a vacuum plate so I don't need film holders. Still, it was a challenge to line up the sheets of film in a grid.
The camera is made by WA Brown and was purchased in 1962. The back measures 24x24" and the copy stand rests on a 15 foot rail [it's big!]. The lens is a 19" Goertz "Red Dot" Apochromatic Artar. I shot this at f90 to get as much depth of field as possible and you can still see that the nose of the teddy bear is out of focus. The illumination is two 500w halogen worklights. The exposure was rated for 4 seconds but I needed 20 because of the terrible reciprocity characteristics of the film used. The picture is shot at 100% reproduction ratio.
The film is Arista.EDU Ultra 100. I used this because it's cheap. I processed the film myself [first time ever processing black & white] and you can see the results of my lack of darkroom skill with the uneven development. I used a Yankee Daylight Development tank which is cheap and which I would not recommend.
This positive image was made by holding my digital SLR over a light table with the negatives arrayed as such [it was kind of like putting together a puzzle]. I wasn't able to get the camera totally overhead hence the slight perspective problem.
Anyway, it was a cool experiment.

Dogs have lived and worked with humans in so many roles that they have earned the unique nickname, "man's best friend", a phrase which is used in other languages as well. They have been bred for herding livestock, hunting (e.g. pointers and hounds), rodent control, guarding, helping fishermen with nets, and pulling loads, in addition to their roles as companions
Dogs Because they give their undying love, affection, and loyalty to you even if you treat them badly.
They will do anything for you, stick by you till death, and risk their lives to protect you. They never judge or criticize and fully accept you for exactly who you are.
You are their sovereign lord and their whole world revolves around you.
# Trust in one another (able to express feelings - including in relation to the other's actions - without the fear of being judged); able to go to each other for emotional support Positive reciprocity - a relationship is based on equal give and take between the two parties.

I took this around midday today.
the film "forma 100" has amazing/appalling reciprocity characteristics.
straight metered time was a fraction of a second.
allowing for a welding glass filter gave me 50 seconds.
Reciprocity failure brought the exposure to a little over 8 (yes 8) minutes!
As my first experiment, I am quite pleased to have got a usable exposure!
Eglise de Souillac (France departement of Lot)
Linhof color with Fujinon-W 150mm f/6.3 (tessar... a bit too contrasted lens)
Fomapan 200 in 4x5 at EI=100 16min due to very non linear reciprocity.
Developped in Pyrocat-HD 1:1:100 9min.
There is a special mask operation (done with Picture Window Pro) to recover the light and the details in the stained-glass windows. The reciprocity failure has induced very overexposed windows but many details remain on the negative. Thanks to a wet-scan that allowed me to recover all the informations (Epson VT750)
