Feeding grain to pigs and chickens, says @JoelSalatin, is ecologically wasteful. On homesteads, pigs foraged and chickens ate kitchen scraps. Herbivore-based cultures relied on nature rather than performing the work of tillage.
[24:30] In the future, we will, of necessity, begin abandoning the petroleum-based, chemically-based, program and will return with our cool infrastructure. We will return to a real-time, carbon-based system.
Now this drove also the whole animal approach. So we talked about herbivores. Grain was way too expensive to feed to an herbivore. I mean, you couldn’t even feed it to an omnivore. So what did you feed to omnivores, pigs and chickens and things?
The reason that all cultures — their dietary base — was either herbivore based — which includes dairy (includes yaks and camels) — herbivore-based or seafood-based — was because those were the only two nutrient-dense dietary basics that could be produced without tillage.
In a day that you had to follow the ox with a stick, tillage was too laborious to be the backbone of anything.
So, in the future, we’re going to revert to that. We’re going to go back to that basis. You want to really eat ecologically? Forget eating chickens or pork. Eat grass-based herbivores. Water buffalo. Llama. Cow. Yak. Whatever. Zebra. Elk. Venison. Groundhog. Gopher. Herbivore!
[26:15] So what about the pigs and chickens? What were they? Their role, historically, was always as a fringe recycler. The pig was always on the outskirts. George Washington, he was so meticulous in his recording keeping in Mount Vernon. He always lamented the pigs, because they could never get them all rounded up at the same time. They could go out once in the fall and round them up. They would always have a few stuck back in the brush that they couldn’t find. They lived in the woods. They lived on chestnuts and acorns. They ate around the edges. In the das before refrigeration, they ate the whey from butter and cheese making. They ate the skim milk. Until 20 years ago, nobody drank skim milk. Skim milk wasn’t even worth drinking. You took the cream off, and you poured the skim milk out for the pigs.
[27:15] And then the chickens were always right up next to the kitchen in the homestead. Why? Because they got all the kitchen scraps. We didn’t have garbage disposals and landfills, and a garbage truck that came and picked up the trash and took it away. So something had to recycle that. All that kitchen scraps. Blemished fruit from the orchard. Blemished vegetables from the garden. Soured milk. Clabber that went bad. It went into the chickens. They were the ultimate recycler. And that’s what fed the poultry and the pork, because grain was too expensive to feed them. We needed all of the grain to bake bread and feed people. And people didn’t eat very much of that, either.
[28:00] Suddenly, now, here we are with this cheap grain thing. We have segregated all of these beautiful, integrated, carbon chains, local chains, these energy flows, all these historically normal energy flows. Now, fifty percent of the human-edible food in the world never gets eaten by humans. It never gets eaten by humans. Ninety-nine percent of it gets landfilled. Then we give greenie awards for somebody the is clever enough to put a pipe in there to get the methane so that we can drive all of the equipment to the landfull. No, no, no. We want want is all of that salvaged, blemished spoiled food, and combine it to the animals that are right there. We want to combine it. We want to integrate it.
[29:10] If we want to be ecological, what we would do is not go to a kitchen waste composting program. We would get a couple of chickens, and bring them into our apartment. They don’t take any more room than the aquarium, or the parakeet cage. One average dog produces more poop than eleven chickens. So we feed them the kitchen scraps. They eat those, and give us eggs. Now we don’t have to have any factory eggs than need to eat grain.
This excerpt was from a lecture given at Colorado College, sponsored by two student groups: EnAct (environmental and social awareness through research, education and action), and the Carnivore Club (promoting social awareness of the benefits and pleasures of meat).
In celebration of Colorado College Earth Week, Joel Salatin, a self-described environmentalist capitalist farmer, will come to lecture. Salatin owns Polyface Farm, where he describes his innovative farming techniques as “in the redemption business: healing the land, healing the food, healing the economy, and healing the culture.” He was profiled in Michael Pollan’s book, “The Omnivore’s Dilemma” and has authored several books including “Folks, This Ain’t Normal,” “Holy Cows and Hog Heaven,” and “The Sheer Ecstasy of Being a Lunatic Farmer.”

Launch of textbook by Fritjof Capra, collecting 40 years of writings with additions by coauthor Pier Luigi Luisi. The lecture shows precise language about the science of systems, with clear references tying together research strands. Mature systems thinkers will be reminded of concepts that they know but may not be immediately salient to their current endeavours. Novice systems thinkers may appreciate the easy pace of the speech, with linkages to other concepts and figures in the systems community.
My forthcoming book is the realization of a dream I have had for many years. It is a multidisciplinary textbook, coauthored with my friend and colleague Pier Luigi Luisi, Professor of Biology at the University of Rome, and to be published by Cambridge University Press in April 2014.
In this book, titled The Systems View of Life: A Unifying Vision, we present a coherent systemic framework that integrates four dimensions of life: the biological, the cognitive, the social, and the ecological dimension; and we discuss the philosophical, social, and political implications of this unifying vision.
To write this book, I went through all my previous books, collected the relevant passages, updated and modified them as appropriate for an undergraduate textbook, and added many new passages in collaboration with my coauthor. So, for me this book is a summary of my work as a writer over the past forty years.
We believe that it will be critical for present and future generations of young students and researchers to understand the new systemic conception of life and its implications for a broad range of professions — from economics, management, and politics, to medicine, psychology, and law. In addition, the book will be useful for undergraduate students in the life sciences and the humanities.
The book offers a broad sweep through the history of ideas and across scientific disciplines. Beginning with the Renaissance and the Scientific Revolution, the historical account includes the evolution of Cartesian mechanism from the seventeenth to the twentieth centuries, the rise of systems thinking, the development of complexity theory, recent discoveries at the forefront of biology, the emergence of the systems view of life at the turn of this century, and its economic, ecological, political, and spiritual implications.
A talk given at Schumacher College (UK), Dartington on May 7th 2014.
The great challenge of our time is to build and nurture sustainable communities, designed in such a manner that their ways of life, physical structures, and technologies do not interfere with nature’s inherent ability to sustain life. To do so, requires a new ecological understanding of life, as well as a new kind of “systemic” thinking.
In this lecture, Fritjof Capra describes that such a new understanding of life in terms of complexity, networks, and patterns of organization, has recently emerged at the forefront of science. He will emphasize, in particular, the new conception of the nature of mind and consciousness, which is one of the most radical philosophical implications of the systemic understanding of life; and the urgency of this new understanding for dealing with our global ecological crisis and protecting the continuation and flourishing of life on Earth.
Fritjof Capra was speaking as part of his short course running at Schumacher College.
I heard Fritjof Capra speak in person, at the ISSS 2006 Sonoma meeting.
Why Architecture is needed even in Agile? (MP3 audio) | Jim Coplien | January 2011 | Business901 May 14, 2014Posted by daviding in Talk Audio Download, Talk Audio Streaming.

Scrum came out of lean and predates agile, says @jcoplien.
[29:30] Everyone thinks that Scrum came out of Agile. Now wait a minute, let’s stop this for a second, because Scrum has been around since 1993 and the Agile manifesto was 2001. How did Scrum come out of Agile? It’s really the other way around. Or, even better, they both came out of Lean. Lean is a funny word that gets associated with different labels. …. [They're] all very, very much in the same cauldron and the same genre of harking back to the original Toyota principles of Lean, whereas Agile is really kind of off somewhere else.
Scrum, as I said, comes from this paper by Takeuchi and Nonaka in “Harvard Business Review” called the “New New Product Development Game” where Takeuchi and Nonaka looked at practices at Honda, at Canon, at NEC, and a lot of other contemporary Japanese corporations — this was about 1984 — most of whom had learned their techniques by some consultants who’d come over from Toyota and taught them the Lean principles.
That’s where Jeff Sutherland got the ideas for Scrum, and that was one of the main influences on Scrum. Some of my research in Bell Labs was another one of the influences on Scrum. In particular, things like stand-up meetings come out of the stuff we did at Bell Laboratories. Then Jeff added incremental development, iterative development, and time boxing. But most of it comes from Lean, absolutely. So if you look at the planning, doing, reflecting, this Kaizen notion, the cycles that we get out of Lean; this is what Scrum is about, absolutely.
Lean may have predispositions in Japanese culture that are uncommon amongst westerners.
[27:00] Joe Dager: What makes Scrum hard to do?
Jim Coplien: Because it’s a discipline. It’s very simple. I mean, it says you cannot work any overtime. So, you know, management cannot come near the end of the release and say, “Well, you need to put in some extra hours here in order to make our commitments.” The other thing that makes it hard is that it runs against some of the prevailing values of industry. Industry says, “We believe that we can commit an arbitrary amount of work to a fixed team and an arbitrary schedule. Well, OK, we know we can’t, but we’ll make it work by adding more people or by adding overtime or by trimming the fat,” which means let’s cut quality here and there.
Scrum is uncompromising. It says, “Well, what we deliver, we’re going to deliver with the promised quality. If we can’t deliver it, then we won’t deliver. We’re going to make it visible. The fact that we make that visible shows that, well, there’s a problem in our process. We estimated wrong. We overcommitted and we need to learn to do better next time.” People hate this notion of failure.
One of the key aspects of Lean that I think the Western world doesn’t understand. In Lean, we keep saying Kaizen, Kaizen, Kaizen. Get better and better and better. Well, you go to the Japanese and they say, “There is no Kaizen without Hansei.” Probably the closest interpretation of the word “Hansei” in English, would be repentance. It’s this deep sense of shame and apology and deep regret for not having built a process that allowed you to meet your commitment. When you fail to meet your commitment, the first step in Kaizen is Hansei, and you don’t see many American managers going around doing Hansei. You certainly don’t see proud nerd software engineers going around doing Hansei.
Scrum is always focused on this Kaizen mind of being able to get better and better and better, and it takes a lot of humility. I think that’s what makes it hard. It takes humility, and the humility takes a high degree of trust between individuals. People have to be allowed to fail so they can learn. I haven’t been in three companies in the past 10 years that had enough trust to do what the Japanese are doing in Kaizen and Lean.

Ward Cunningham describes the features in federated wiki new to the original 1994 wiki technology at the Mountain West Ruby Conference 2013.
This last year I set out to do for numbers what I had done for words, give them depth and meaning that ordinary people can depend on every day. [....] My quest has been to make knowing and using data an everyday thing. This means the study of data must be an everyday thing too. To this end I’ve pushed visualization, I’ve pushed domain specific markups, I’ve pushed streaming measurements. But through this I’ve retained wiki’s greatest strength: the ability to create with those who we have just met and don’t yet have reason to trust. Finding trust on the modern web may be this year’s biggest accomplishment.
The Mountain West Ruby Conference 2013 was attended by Mike Farmer, who wrote a digest at http://blog.endpoint.com/2013/04/pounding-simplicity-into-wiki.html , including:
[....]. The promise of this new kind of wiki is to give numbers depth and meaning that ordinary people can depend on every day.
This means data visualization intermixed with context. For example, a weather map can show you numbers on a map to tell you temperatures. A meteorologist doesn’t just see a number, he sees the actual weather, the hot and cold, the wind or the rain, etc. Data visualizations like a wind map excel at helping users to visually see the wind in region.
To accomplish this promise, Cunningham implemented a new kind of wiki. The main difference in this new wiki is that the data is federated among several different locations on the web and then assembled in the browser. You can think of it as a traditional mashup. The wiki content is both self generated and programatically generated from data on the web or attached to the web via some device.
- 0 Story: Pages with datasets, images and paragraphs with history (versions).
- 1 Binding: Attaches the data to different versions of the page revisions.
- 2 Attribution: Source is dynamically generated so that it can be tracked back.
- 3 Link Context: Links to other pages on other servers give hints to tell you where the data originates.
- 4 Neighborhood: Click on a page that doesn’t exist (red link) server looks for similar page on other wikis in the federated network.
- 5 Search: Global search looks in all the wikis in the federated network.
The principle behind this project is one of discovery. As the development continues, the possibilities for it increase and new thoughts and ideas are discovered. This was talked about in a talk by Bret Victor called Inventing on Principle. If you were to compare this to agile, it might look like this:

“For Your Eyes Only” music and main title production (1981) December 25, 2013Posted by daviding in Music.
Tags: 007, bill conti, for your eyes only, james bond, sheena easton
add a comment
On “For Your Eyes Only”, music production reshaped Sheena Easton‘s Scottish Accent. After I caught a bit of the James Bond movie on holiday television, I was intrigued to look into the song. I found a version of Sheena Easton performing in 1982 in Live at the Palace (Hollywood) (starting around 54m32s), where her pronunciation is more Scottish.
The music style in James Bond films shifted in 1981, says Donald A. Guarisco in allmusic.com.
This film was also noticeable for replacing regular series soundtrack composer John Barry with Bill Conti, a composer best known for his work on the Rocky films. Conti keeps For Your Eyes Only‘s score full of symphonic grandeur and spy film theatrics, but also adds several new elements to update the sound to fit the early 1980s. For instance, Conti adds elements of dance and funk music to the action cues: “A Drive in the Country” and “Melina’s Revenge” both work funky bass lines, roaring electric guitar leads, and whooping synthesizer lines in with the standard orchestral elements. The modernized tone also extends to the film’s Sheena Easton theme song: it replaces the lush strings and brassy orchestrations that typically dominated Bond theme songs with a minimalist style built on synthesizers. However, Conti proves elsewhere that he could comfortably write music in the traditional vein without utilizing any electronic or pop elements:
Production of the song is credited to British record producer Christopher Neil, who had previous worked on Sheena Easton’s debut album Take My Time. The songwriters were Bill Conti (music) and Mick Leeson (lyrics). Production of the soundtrack is credited to Bill Conti. In a 2012 Emmy Tv Legends interview (around 55h30m), Bill Conti said that John Barry was unavailable at development of For Your Eyes Only and recommended him to write the score. Cubby Broccoli asked Bill Conti to come to England, for 3 months with his family, to write.
Bill Conti: I wanted Barbra Streisand to write the lyrics to the song, and I wanted Donna Summer to sing it. I thought I was clever. I actually talked to Barbra , who was doing Yentl, who couldn’t — she was very busy. And the studio suggested Sheena Easton to sing the song. I heard a thing called “Morning Train”, that was a big hit of hers. I said, well, maybe, she’s got a voice, maybe she doesn’t have a voice, I can’t tell. I still wanted a big star. Sheena was in London when I was in London, so I listened to her. She was really good. She’s a really good singer. That material she sang, hit or not, was not a Dusty Springfield “Bond singer”. I thought “Bond singer”, to this era, was a woman who could belt it out there.
Anyway, I wrote a song called “For Your Eyes Only”, because you’re obligated, when you do a Bond movie, to include the title in the song. So my lyricist, who was Sheena’s pick, because — who do you like to work with? Fine. Mick Leeson, he’s a very good lyricist — he ended the song “For Your Eyes Only” I would do this for you, I’d do that for you, I’d do it for your eyes only. It’s a wonderful song.
I made an appointment with Cubby Broccoli. I did a little demo. I had a little cassette. After three minutes, it ends “For Your Eyes Only”. But I have a lunch with the guy who does the great main titles. Maurice Binder. Little guy. Little guy who loved Sheena, who is a little girl. So he put her in the main title. But he says, at lunch, Bill, I know you guys have a problem with the main title, you have to put the thing in it. But I really like it when the main title comes on, and the main title of the song. It’s really “Goldfinger”, those great ones, all at the same time. And I’m thinking, well, after 3 minutes, my song ends “For Your Eyes Only”. I wish I could do that one.
Interviewer: And he wanted it to start “For Your Eyes Only”.
Bill Conti: So I called Cubby Broccoli, and said, look, cancel! I went to the lyricist and said, look, you, this song begins “For Your Eyes Only”, and I don’t care what you do after that. And that’s how it was.
The finalization of the lyrics and scoring would have happened in late 1980 or early 1981. The rough cut version has different lyrics, unfinished music and graphics shown in this Rare Demo version posted by thedarksideBJ.
To compare the final version with the rough cut, see the “Record and Record Combined Stereo” mashup by DcsabaS.
In 1982, the phrasing of the song by Sheena Easton was still close to the film version, but the reemergence of a Scottish accent appears in The Tonight Show (with Johnny Carson) performance.
By 1984, her Scottish accent shows up strongly in the Fest de Viña performance.
To triangulate dates in the early 1980s when Sheena Easton was performing, validate with the length of her hair!
The main title music could have been different. Alternatives are cited in “For Your Ears Only” | Jude Rogers | Oct. 31, 2008 | The Guardian at http://www.theguardian.com/music/2008/oct/31/james-bond-songs . Blondie offered a version of “For Your Eyes Only” that was released on the 1982 album “The Hunter“. The phrase “For Your Eyes Only” shows up at 1:15 into the song, so a potential disagreement with Maurice Binder was pre-empted!
The larger context of the movie For Your Eyes Only has been captured in “James Bond Retrospective: For Your Eyes Only (1981)” | Chris Wright | May 1, 2012 | whatculture.com at http://whatculture.com/film/james-bond-retrospective-for-your-eyes-only-1981.php
This movie is reputed to have bailed out United Artists as a company.
The film saved United Artists from financial ruin. At the time of the film’s release, the studio was still reeling from Michael Cimino’s Heaven’s Gate (1980), a notorious $40,000,000 bomb that was about to force UA to file bankruptcy. When this film took in a worldwide gross of $194,900,000, the studio was saved and afterwards turned its focus toward blockbusters and less on personal films.
It would be the last independent 007 movie by United Artists.
Last EON Productions James Bond movie soley released by United Artists. They would merge with MGM before the release of the next Bond film, Octopussy (1983).

Risk taking in casual sessions with peers now lacks intimacy, says @PatMetheny, since observers can make every event a world premiere by recording anywhere at any time. Private sessions are the exception rather than the rule. In the JazzFM91 interview, around 21:25:
Bob Barker: On the technology front, you live in New York City, arguably kind of the heartbeat of the jazz world. You’ve also been known, over your career, to be the guy that shows up somewhere and jams, pulls out a guitar, unannounced, and walks in and starts playing with musicians. Has new technology, and where you are now in your career, changed any feelings you have about that kind of casual nature you used to have with showing up and playing with people?
Pat Metheny: I am really sad to say this, but it’s impossible now. You can’t do that anymore, or at least you can’t do it on a casual basis. There is a way to do it, which is to accept that now we do live in a different era. But, there is no intimacy anymore. Everything you do is a world premiere, because the minute you do it, somebody somewhere could be — they may be or they may not be, but we have to assume that they probably might be — recording or filming it. You can’t just do a little thing in Rimouski anymore, and try something out. Everything you do — it doesn’t matter if you’re at the North Pole — the minute you do it, it’s everywhere. That’s going to change things.
To a certain degree, there’s an aspect to this that I also acknowledge and accept, which is that it’s an age thing. I’m old school, to the degree that I want to feel a direct connection to the people I’m performing to, and what’s happening at that momemt.
Bob Barker: Is that an age thing, Pat? Is that passé?
Pat Metheny: I’ve got a feeling it’s passé. We’ve moved into new territory,now. I also anticipate that there will be a generation of musicians who will thrive in this environment. I probably won’t be one of them, because I do represent myself in a way, much like we’re having a conversation right now. You and I are speaking, but I am aware that there is an audience of people listening. There are certain things I’m not going to say right now, and you would probably get fined, if I did. Certain words, or this or that.
Bob Barker: There are boundaries to it.
Pat Metheny: There are boundaries to it. There used to be an environment for musicians where you were boundary-free, where there were no consequences to trying this or trying that. Those days are over. We are in a world now where everything is kind of public. That fights a little bit against the idea of risk-taking, unless that’s baked in. Unless, that’s baked in. I anticipate it will be, with the next generation of people.
The interview begins with an introduction by Bob Barker:
Pat Metheny has been redefining the sound of jazz for close to 40 years.
He’s taken the music to places its never gone before as well as always celebrating the history of jazz and the musicians that have come before him.
From 1976’s Bright Size Life to the recently released collaboration with John Zorn, Pat Metheny has released countless albums as leader of the Pat Methney Group,solo recordings, duets…soundtracks….all in all Pat has multiple Gold records and 20 Grammy Awards to his name.
Constantly searching, pushing, inspiring and educating Pat Metheny joined us at our JAZZFM91 Studios to talk about his amazing career, the Orchestrion project and more!

After agile estimate and agile planning, prioritizing the product backlog has a few more techniques worth watching. Mike Cohn has a variety of techniques described in prior years, but this set of slides hasn’t been as popular as the ones on planning and estimating. The content tends to run:
Approaches to prioritizing include:
- Kano analysis
- Expert opinion
- Theme screening
- Theme scoring
- Relative weighting
- Financial analysis
Kano analysis maps the presence of features against satisfaction, as:
- Mandatory / Baseline: must be present for users to be satisfied
- Linear: the more of it, the better
- Exciters / Delighters: Features a user doesn’t know she wants, until she sees it
The other approaches are more typical scorecarding approaches.
Here’s a slide deck dated June 8, 2010.

Chinese Dining Etiquette by @ntdOTGW explains practices commonly adopted by children regularly attending parents’ dinners, which may be unknown by others. Entertaining 5-minute video describes how Chinese parents should have taught their children:
1. Where to sit?
- Seat of guest of honour faces the door.
- Next most important to right of guest of honour, and to the left of guest of honour.
- Person paying the bill faces the guest.
2. How to order?
- One person orders for table, sometimes with host ordering a few dishes and then asking others for additional dishes
- Even number of dishes
3 and 4. How to Pour Tea and Show Gratitude
- Tea handle with right hand, top with left hand
- Teapot top partially off signals for more water, teapot top entirely off is bad luck.
- Verbal thank you, or tap the table with two fingers.
5. Chopsticks handling
- Chopstick is extension to fingers, so don’t point
- Don’t stand chopsticks upright in rice, which looks like incense in dishes left to honour the dead
6. How to Eat Your Food
- On the lazy susan, the most senior person selects first
- Take a small portion to ensure everyone gets some
7. How to Eat Fish
- When whole fish is served, once one side is eaten, never flip the fish over; lift out the backbone of the fish
8. How to Pay the Bill
- Guests should never split the bill, as that would be ingracious, saying that the host could not afford the bill, or that the hospitality is not appreciated.
- Guest should offer to pay the bill a few times

On our family visit back to our ancestral village at Lougang (or Lowkong), the members of the collective group mostly spoke no more than two of four dialects, from the heritage Toisanese, to local standard Cantonese, the modern Mandarin, and the new world English. This meant conversations with multiple translations from the 92-year-old grandfather down to the pre-school great grand-daughter.

The shift from traditional Chinese characters to simplified is compared to Orwell’s 1984 newspeak. Our sons who studied in Mandarin language classes at university in Beijing may have missed the deeper cultural understanding of the original ideograms.

Release and iteration planning described in a 57-minute video, is better as a third in series, following the video on Agile Estimating. Mike Cohn presents:
- after the user stories have been created, and duration (as story points) have been estimated …
- velocity is the amount of the work completed per iteration;
- planning in five scenarios:
- 1. a team with historical data;
- where confidence intervals can be calculated from historical data
- 2. fixed-date plans;
- with partitions of “will have”, “might have” and “won’t have”;
- 3. fixed-scope plans;
- where a date range can be provided;
- 4. a team with no velocity data;
- where a first iteration breaks features (backlog items) into tasks, and hours are estimated for each task; and then
- the second iteration may be estimated as a range, and/or compared with other teams; and
- 5. a team changing size
- where the average velocity change can be tracked.
- 1. a team with historical data;
Velocity is perhaps the most useful metric available to agile teams. In this session we will look at advanced uses of velocity for planning under special but common circumstances. We will see how to forecast velocity in the complete absence of any historical data. We will look at how a new team can forecast velocity by looking at other teams. We will see how to predict the velocity of a team that will grow or shrink in size. Most importantly we will look at the use of confidence intervals to create plans we can be 90% confident in, even on fixed-price or fixed-date contracts.

This 59-minute video on Agile Estimating is better sequenced for viewing secondly, following the video on User Stories. Mike Cohn presents:
- estimating size (before) deriving duration (with a range);
- story points as relative effort for a user story in a product backlog;
- ideal time (to complete) as compared to elapsed time (with interruptions);
- “Planning Poker” as an iterative approach to estimating (collaboratively).
The first step in creating a useful plan is the ability to estimate reliably. In this session we will discuss how to do this. We will look at various approaches to estimating including unit-less points and ideal time. The class will present four specific techniques for deriving reliable estimates, including how to use the popular Planning Poker® technique and other techniques that dramatically improve a project’s chances of on-time completion.

This 52-minute video is a comprehensive introduction to User Stories, as practiced in Agile Development. Mike Cohn presents:
- resource allocation under imperfect schedules as a shared problem between developers and business people;
- user stories as 3 C’s: the Card supporting Conversations with Confirmation (of conditions of satisfaction);
- story details as (i) conditions of satisfaction, or (ii) sub-stories;
- epics as large stories, and user stories clustered into themes;
- story-writing workshops as supporting participative design.
While this talk was the last for the day, it’s better as the first for viewing as an easy introduction to the agile way.
Mike Cohn – User Stories for Agile Requirements from NDCOslo on Vimeo.
The technique of expressing requirements as user stories is one of the most broadly applicable techniques introduced by the agile processes. User stories are an effective approach on all time constrained projects and are a great way to begin introducing a bit of agility to your projects.In this session, we will look at how to identify and write good user stories. The class will describe the six attributes that good stories should exhibit and present thirteen guidelines for writing better stories. We will explore how user role modeling can help when gathering a project’s initial stories.
Because requirements touch all job functions on a development project, this tutorial will be equally suited for analysts, customers, testers, programmers, managers, or anyone involved in a software development project. By the end of this tutorial, you will leave knowing the six attributes of a good story, learn a good format for writing most user stories, learn practical techniques for gathering user stories, know how much work to do up-front and how much to do just-in-time.

Sustainable Development Goals must sustain people and planet, experts say | March 20, 2013 | sciencedaily.com March 24, 2013Posted by daviding in Talk Video Streaming.

Six Sustainable Development goals from U.N. to supersede Millennium Development Goals that expire 2015, based on new appreciation of anthropocene.
In the wake of last week’s meetings at the UN on the definition of the Sustainable Development Goals (SDGs), a group of international scientists have published a call in the journal Nature today, arguing for a set of six SDGs that link poverty eradication to protection of Earth’s life support. The researchers argue that in the face of increasing pressure on the planet’s ability to support life, adherence to out-dated definitions of sustainable development threaten to reverse progress made in developing countries over past decades. [....]
The team asserts that the classic model of sustainable development, of three integrated pillars — economic, social and environmental — that has served nations and the UN for over a decade, is flawed because it does not reflect reality. “As the global population increases towards nine billion people sustainable development should be seen as an economy serving society within Earth’s life support system, not as three pillars,” says co-author Dr. Priya Shyamsundar from the South Asian Network for Development and Environmental Economics, Nepal.
The researchers say that the Millennium Development Goals (MDGs), set to expire in 2015, have helped focus international efforts on eight poverty-related goals. However, despite successes in some areas — the number of people living on less than one dollar a day has been more than halved — many MDGs have not been met, and some remain in conflict with one another. Economic gains, for example, have come at the expense of environmental protection. Politicians are struggling to link global environmental concerns with addressing poverty.
The new set of goals — thriving lives and livelihoods, food security, water security, clean energy, healthy and productive ecosystems, and governance for sustainable societies — aim to resolve this conflict. The targets beneath each goal include updates and expanded targets under the MDGs, including ending poverty and hunger, combating HIV/aids, and improving maternal and child health. But they also define a set of planetary “must haves”: climate stability, the reduction biodiversity loss, protection of ecosystem services, a healthy water cycle and oceans, sustainable nitrogen and phosphorus use, clean air and sustainable material use.

“Ending poverty and safeguarding Earth’s life support system must be the twin priorities for the Sustainable Development Goals, says Johan Rockström, centre director and a co-author of the Nature article.
Together with the international team he identified six goals that, if met, would contribute to global sustainability while helping to alleviate poverty. [....]

Not infrequently, competent individuals come together to form an incompetent team, says Lorelei Lingard.
Joe got competent care in hospital. He recovered from his pneumonia. He got competent care from his family doctor, his diabetes specialist, his homecare nurses and the pharmacist. Each of those individuals, within their scope of practice, and acting on the information at hand, did the right thing for Joe. But the sum total of those care events is not overall competent care for Joe. [around 4:50]
Now this is a very complex problem, and it’s being tackled from a number of different angles. Systems engineers are trying to understand it better, to improve the situation. Organizational scientists are trying to work on it. Sociologists are working on it. Tonight, I’m going to shed some light on this problem from my perspective of a communications researcher trying to improve medical education. [around 5:20]
There are significant barriers that make it difficult for individual competence to translate into collective competence. I’m going to focus on three. [around 5:45]
The first is scientific reductionism. This refers to the way that we tackle complex scientific phenomena, by breaking them down into their component parts. [....] [around 6:00]
The second barrier between individual and collective competence is specialization. [....] [around 6:20]
The third barrier between individual and collective competence is the very concept of individual competence itself. The goal of producing an individually competent healthcare provider, with their own specific tightly-bounded expertise drives everything: in health profession education generally, and medical education specifically. [around 7:00]
Together, and kind of paradoxically, these three factors combine, to produce one of healthcare’s greatest weaknesses. That is, that providers work in isolation from one other, each person focused on the particular issue about which they are an expert. When that happens, patients can fall into the cracks between the individually competent healthcare providers. [around 8:00]
What do we need to adapt from? I would argue that we need to adapt from our exclusive focus on the goal of individual competence. Individual competence is a set of pervasive, and rarely challenged assumptions. It’s not unique to medical education, it’s true of education everywhere.
I would like to touch on three ways in which we are, right now, moving towards collective competence. [around 12:20]
Joe travels through the healthcare system more quickly than his healthcare information does. We have the technology to address this problem, to move information more efficiently. One example … is the global medication electronic record. [around 13:40]
The shift to delivery primary care through family health teams. [....]
The third way in which we’re moving toward collective competence is a more strategic way. [....] Take a look at the healthcare system, find those points in the system where a failure of collective competence can have dire consequences, and build initiatives to support collective competence in those moments.
Lorelei Lingard is founding director and senior scienist at the Centre for Education Research and Innovation, at the Schulich School of Medicine and Dentistry, at the Western University. Here’s her bio:
Dr. Lorelei Lingard is a leading researcher in the study of communication and collaboration on healthcare teams. She is a Professor in the Department of Medicine at the University of Western Ontario (UWO) and the inaugural Director of the Centre for Education Research & Innovation at the Schulich School of Medicine & Dentistry. Dr. Lingard obtained her Ph.D. in Rhetoric from the English Department at Simon Fraser University, specializing in rhetorical theory, genre theory, medical discourse, and qualitative methodology. As a rhetorician, she investigates ‘language as social action’: that is, how social groups use language to get things done, and how that language acts on them, their identities, their purposes, their situations, and their relationships. Her research program has investigated the nature of communication on inter-professional healthcare teams in a variety of clinical settings, including the operating room, the intensive care unit, the internal medicine ward, the adult rehabilitation unit, and the family health centre.
