Holy war, holy peace_ how religion can bring peace to the Middle - Original PDF
نویسندگان: خلاصه: The complexity of human social relationships seems to require a degree of healthy conict, by its very nature.1 Yet it is clear that what is a normal part of social intercourse often turns into a phenomenon that is destructive to at least one but usually all parties to a conict over time. This is as true in the life of individuals as it is true in the life of peoples, nations, and religious communities
Liberator Band 1 Ausgabe 2 - PDF
نویسندگان: خلاصه: Do you want to recycle your electrical and electronic equipment for free? Learn more Molly Birch has everything a poor City girl could want: an apartment with her own bedroom, two living parents and a boyfriend. But none of it is stable when the anonymous Government dictates all aspects of citizens' lives, from food and medical care access to the number of children couples can have. Molly is sixteen and now old enough to apply for a Courtship with her boyfriend, Gavriel Kingsley. Courtships are the only legal form of romantic relationship for unmarried citizens over sixteen and are the step leading to marriage. Molly and Gavriel have waited years to apply. However, things don't go as planned following their application and medical tests during Clinic Day. The fallout leaves Molly's world shattered, and she makes a desperate and dangerous escape from the only life she's ever known to keep control over something after the Government takes everything from her. On her journey, Molly makes new friends, discovers her dad's secret past, learns her heart's true feelings and finds out how she can make a difference in the City for everyone, not just herself.
Indigenous Resistance in the Digital Age: On Radical Hope in Dark Times - Original PDF
نویسندگان: خلاصه: 1 CHAPTER 1 Introduction: Wild Things Written with my mountain home and First custodians Aki Nabalu and Odu Nabalu This is a chapter about place and Indigenous resistance. I am writing out of the politics of the two homelands I occupy in my mind as an Indigenous woman moving between two worlds. My voice is the bridge between two worlds. Places are never captured precisely in words or pictures. They are always more. Mount Kinabalu, the highest peak on Borneo island, is dotted with rock edges. Before it was damaged by an earthquake in 2015, one rockface took the shape of a donkey’s ear and was named so. It was the image that came to mind for the person who named it long ago but I have to say: What a diminutive title! I have to muse when this person looked up to that enor- mous pinnacle whether he heard a donkey’s ‘hee-haw’ braying down to him. Conservationist David Attenborough climbed Mount Kinabalu in 1975, describing a landscape of magical beauty. Granite pinnacles jutted skyward. The sky seemed to move as you climbed, as did the rockpools at the peak reflecting the stars. We learn the ascent was challenging, that nature came bearing gifts.

Photo credit Moffen Gondoloi Gifts that carried not just life but ominous signs. Pitcher plants shimmered with poison water, tricking insects in a dance of death. And so we learn of nature’s realities. Life and death, doom and gloom, smoldering side-by-side. Words. Pictures. A perspective from high up. Reading his words today, Attenborough’s (1975) nature walk up the mountain rumbles with sound. Frogs bleeeerrk-bleeeerrk at the lower reaches. Birds trill louder and louder farther up the trail. Birds in this part of the world do not fly away on approach; so tame, they scurry at the walker’s feet in a cheeky game of chasey. Come play with us, the birds seem to sing. At the top, where I imagine the walkers resting, perhaps stooping to drink water from mirrored rockpools, the icy wind cuts through bodies razor sharp. But oh how the top is worth the hike! The panorama magnifi- cent—even as you become more conscious of your breath, wind howling in your ears. Imagine this: terrestrial moss, lichen, liverwort, tiny trees clinging to rock icicles for dear life. Imagine the sounds and sights, sacred custodian of my homeland Aki Nabalu tells me. O. GUNTARIK 3 Let us consider this and listen, sings another custodian Oku Nabalu. Both of them are caretakers of this mountain place. My original home. Custodian ancestors help us tell the histories of place and the legacies of our survival. They are our original storytellers. They evidence the ways storytelling pioneer modes of knowing, merging animal and human, the wild and the tame, nature and machine to draw attention to the political dimensions of our existence (see Seton 1898; Cloos 1954; Carson 1962). This politics draws out the musical nature of stories to crystallize purpose and meaning. Listen to the words, for instance, of Australian poet Eileen Chong (2021, 73). ‘There is merit// in quietude, in the precise layering of sound, /image, and object. In the simple acts of walking, /waiting/and witnessing’. A precision to sound, image, object. An intention. Image and object and language come into play for me too. Words offer ways to see, to hear, to read the landscape. The world tilts like an optical illusion or like the multicoloured gems in a child’s kaleidoscope into new configurations of speech. Poets sculpt history into story. So I must pose new questions of life, nature and humankind. I am that tree clinging to bare life on the mountain. Maybe it takes more balls to survive and to talk this way. We need a new way to think about theory, to bring ideas into practice and the world. Praxis we might say. Activism working with reflection, as Paulo Freire (1968) claims. So I am reflecting with Attenborough and the First Custodians on a “sound walk” up a mountain ridge that today rises above a surrounding plateau of a disappearing jungle with a disconcerting backdrop. Dwindling rice plantations. An invasive eyesore of African palm. This is also the home- land of my ancestors: Dusun people, an Indigenous hilltribe of Borneo who were once subsistence farmers. Who share land with the governing Malay, and multiple generations of Indian and Chinese migrants, along with more than sixty Indigenous groups. It is an incisive and empowering moment in my readings of walks through the wilderness, reseeing a don- key’s ear and ‘other peaks...labelled rather unimaginatively...I could not help reflecting that local Dusun names would have been far more appro- priate and musical.’ Attenborough’s words (1975, 103).
Hope for a Heated Planet: How Americans Are Fighting Global Warming and Building a Better Future - Original PDF
نویسندگان: خلاصه: am finishing this book in the final days of the George W. Bush adminis- tration. For those of us who love the environment and long for peace, it has been a dark time. Through it, I have often thought of the words of the poet Theodore Roethke that I first heard from scholar and activist Robert Jay Lifton: “In a dark time, the eye begins to see.” The first light of dawn is now visible as the Democratic candidate, Senator Barack Obama, pushed by a growing grassroots movement, embraces action on climate change. To a lesser degree, though far more than President Bush, so does the Republican contender, Senator John McCain. That was far from the case when I began this project at the height of the president’s wartime popularity. This has turned out to be a book as much about hope and democracy as it is about global warming. Its central theme is that you and I can change history. What we believe, what actions we take, actually matter. It is an idea central to democracy. And it should give us hope. I disagree, strongly, with those who believe the American public has turned into a hopeless gaggle of consumers and couch potatoes who are content to let others rule their lives—or destroy the planet. At the height of President Bush’s popularity and influence it may have appeared that way. But national security and environmental degradation (especially global climate change) are complex, difficult, and abstract sub- jects. It has taken some time for us Americans to grasp the gravity of our situation, from melting ice caps to Iraq. This is especially true when our media mostly cover the White House and the Pentagon—regardless of the occupants—and report each utterance as gospel. Meanwhile, most of us are busy with jobs, families, and problems near home that we can actually see and do something about. The result has been that global warming—caused by the vast outpour- x P REFACE ings of carbon dioxide (CO2) and other pollutants from our cars, buildings, and factories—has increased and is picking up speed. But at the same time, so has a growing and revived environmental movement. It is joined now with new allies from the religious community, business, labor, medical and public health professionals, educators, and more. This new climate move- ment has deep roots in the big environmental groups, too often ignored or derided, that have been working to warn us and prevent global climate change since the elder George Bush’s administration in the 1980s. Their work is now bearing fruit. The public is becoming aroused and engaged. And, as a result, we will have a new, much more climate-friendly president and Congress in 2009. This book tells that story and also ex- plains the basics of climate change and its effects on human health and well-being—not just on polar bears and penguins. But Hope for a Heated Planet is finally about solutions to our dilemma. I’ve tried to give you the best steps you can take, both personal and political, to make a difference and to get involved. Like most authors, I like to imagine, of course, that our new president will take to heart every word I have poured out here. But even more impor- tant is that you do. My mother, Margaret Kirkland Musil, died after ninety- one wonderful years as I was writing. She taught me to love life, to love nature, to learn, to have faith, and to act on my beliefs. My first grandchild, Catherine Kirkland Unruh, was born shortly after. She will need the same lessons. So will all our children and grandchildren. Global climate change, we now know, can be prevented by building a vi- brant, healthy economy that does away with the belching furnaces, smoke- stacks, and combustion engines from the outmoded technologies of the nineteenth and twentieth centuries. But in a democracy, that will depend not on our new president, or the one after that. It is up to us. And the signs now are that many, many citizens and their organizations in this great na- tion are indeed aroused. But to prevail, we will need even more. That is really why I have written. I want you and your family and friends to join with me and millions of other Americans in making history. Nobody else can, or should, do it for you
Medical Ethics A Very Short Introduction Tony Hope - Original PDF
نویسندگان: خلاصه: The fox represents those who pursue many ends, often unrelated and even contradictory, connected, if at all, only in some de facto way, . . . [who] lead lives, perform acts, and entertain ideas that are cen- trifugal rather than centripetal . . . seizing upon the essence of a vast variety of experiences . . . without . . . seeking to fit them into . . . any one unchanging, all-embracing, . . . unitary inner vision. Berlin gives as examples of hedgehogs: Dante, Plato, Dostoevsky, Hegel, Proust, amongst others. He gives as examples of foxes: Shakespeare, Herodotus, Aristotle, Montaigne, and Joyce. Berlin goes on to argue that Tolstoy was a fox by nature but believed in being a hedgehog. 4 Medical Ethics 2. Are you a hedgehog or a fox? I am a fox, or at least would like to be. I admire the intellectual rigour of those who try to produce a unitary vision, but I prefer the rich, contradictory, and sometimes chaotic visions of Berlin’s foxes. I do not, in this book, attempt to approach the various problems I discuss from one single moral theory. Each chapter considers an issue on which I argue for a particular position, using whatever methods of argument seem to me to be the most relevant. I have covered different areas in different chapters: genetics, modern reproductive technologies, resource allocation, mental health, medical research, and so on; and have looked at one issue in each of these areas. At the end of the book I guide the reader to other issues and further reading. The one perspective that is common to all the chapters is the central importance of reasoning and reasonableness. I believe that medical ethics is essentially a rational subject: that is, it is all about giving reasons for the view that you take, and being prepared to change your views on the basis of reasons. That is why one chapter, in the middle of the book, is a reflection on various tools of rational argument. But although I believe in the central importance of reasons and evidence, even here the fox in me sounds a note of caution. Clear thinking, and high standards of rationality, are not enough. We need to develop our hearts as well as our minds. Consistency and moral enthusiasm can lead to bad acts and wrong decisions if pursued without the right sensitivities. The novelist, Zadie Smith, has written: There is no bigger crime, in the English comic novel, than thinking you are right. The lesson of the comic novel is that our moral enthusiasms make us inflexible, one-dimensional, flat. This is a lesson we need to take into any area of practical ethics, including medical ethics. What better place to start this tour of medical ethics than at the end, with the thorny issue of euthanasia? 6 Medical Ethics Chapter 2 Euthanasia: good medical practice, or murder? Good deeds do not require long statements; but when evil is done the whole art of oratory is employed as a screen for it. (Thucydides) The practice of euthanasia contradicts one of the oldest and most venerated of moral injunctions: ‘Thou shalt not kill’. The practice of euthanasia, under some circumstances, is morally required by the two most widely regarded principles that guide medical practice: respect for patient autonomy and promoting patient’s best interests. In the Netherlands and Belgium active euthanasia may be carried out within the law. Outline of the requirements in order for active euthanasia to be legal in the Netherlands 1. The patient must face a future of unbearable, interminable suffering. 2. The request to die must be voluntary and well-considered. 3. The doctor and patient must be convinced there is no other solution. 4. A second medical opinion must be obtained and life must be ended in a medically appropriate way.
Adaptive Optics for Vision Science Principles Practices Design and Applications - Original PDF
نویسندگان: خلاصه: The high transverse resolution of retinal imaging systems equipped with adaptive optics provides a unique opportunity to record these eye move- ments with very high accuracy. Putnam et al. showed that it is possible to record the retinal location of a fixation target on discrete trials with an error at least 5 times smaller than the diameter of the smallest foveal cones [63]. We used this capability to measure the standard deviation of fixation positions FIGURE 1.7 Images of the cone mosaics of 10 subjects with normal color vision, obtained with the combined methods of adaptive optics imaging and retinal densi- tometry. The images are false colored so that blue, green, and red are used to repre- sent the S, M, and L cones, respectively. (The true colors of these cones are yellow, purple, and bluish-purple). The mosaics illustrate the enormous variability in L/M cone ratio. The L/M cone ratios are (A) 0.37, (B) 1.11, (C) 1.14, (D) 1.24, (E) 1.77, (F) 1.88, (G) 2.32, (H) 2.36, (I) 2.46, (J) 3.67, (K) 3.90, and (L) 16.54. The proportion of S cones is relatively constant across eyes, ranging from 3.9 to 6.6% of the total population. Images were taken either 1° or 1.25° from the foveal center. For two of the 10 subjects, two different retinal locations are shown. Panels (D) and (E) show images from nasal and temporal retinas, respectively, for one subject; (J) and (K) show images from nasal and temporal retinas for another subject. Images (C), (J), and (K) are from Roorda and Williams [52]. All other images were made by Heidi Hofer. (See insert for a color representation of this figure.) (From Williams and Hofer [57]. Reprinted with permission from The MIT Press.) across discrete fixation trials, obtaining values that ranged from 2.1 to 6.3 arcmin, with an average of 3.4 arcmin, in agreement with previous studies [63, 64]. Interestingly, the mean fixation location on the retina was displaced from the location of highest foveal cone density by an average of about 10 arcmin (as shown in Fig. 1.8), indicating that cone density alone does not drive the location on the retina selected for fixation. This method may have interesting future applications in studies that require the submicron registra- tion of stimuli with respect to the retina or delivering light to retinal features as small as single cells. Whereas the method developed by our group can only record eye position on discrete trials, Scott Stevenson and Austin Roorda have shown that it is possible to extract continuous eye movement records from video-rate images obtained with an adaptive optics scanning laser ophthalmoscope (AOSLO) [66]. Eye movements cause local warping of the image within single video frames as well as translation between frames. The warping and translation information in the images can be used to recover a record of the eye move- ments that is probably as accurate as any method yet devised. This is illus- trated in Figure 1.9, which compares the eye movement record from the AOSLO with that from a Dual Purkinje Eye Tracker. The noise in the AOSLO trace is on the order of a few arc seconds compared to about a minute of arc for the Dual Purkinje Eye Tracker. Note also the greatly reduced overshoot following a saccade in the AOSLO trace. These overshoots are thought to be partly artifacts caused by lens wobble following the saccade and do not reflect the true position of the retinal image. The AOSLO is not susceptible to this artifact because it tracks the retinal position directly rather than relying on reflections from the anterior optics.
A devil's chaplain: reflections on hope, lies, science, and love - Original PDF
نویسندگان: خلاصه: The first essay in this volume, A Devil's Chaplain (1.1), has not previously been published. The title, borrowed by the book, is explained in the essay itself. The second essay, What is True? (1.2), was my contribution to a symposium of that name, in Forbes ASAP magazine. Scientists tend to take a robust view of truth and are impatient of philosophical equivocation over its reality or importance. It's hard enough coaxing nature to give up her truths, without spectators and hangers-on strewing gratuitous obstacles in our way. My essay argues that we should at least be consistent. Truths about everyday life are just as much - or as little - open to philosophical doubt as scientific truths. Let us shun double standards. At times I fear turning into a double standards bore. It started in child- hood when my first hero, Doctor Dolittle (he returned irresistibly to mind when I read the Naturalist's Voyage of my adult hero, Charles Darwin), raised my consciousness, to borrow a useful piece of feminist jargon, about our treatment of animals. Non-human animals I should say, for, of course, we are animals. The moral philosopher most justly credited with raising today's consciousness in this direction is Peter Singer, lately moved from Australia to Princeton. His The Great Ape Project aims towards granting the other great apes, as near as is practically possible, civil rights equivalent to those enjoyed by the human great ape. When you stop and ask yourself why this seems so immediately ridiculous, the harder you think, the less ridiculous it seems. Cheap cracks like 'I suppose you'll need reinforced ballot-boxes for gorillas, then?' are soon dispatched: we give rights, but not the vote, to children, lunatics and Members of the House of Lords. The biggest objection to the GAP is 'Where will it all end? Rights for oysters?' (Bertrand Russell's quip, in a similar context). Where do you draw the line? Gaps in the Mind (1.3), my own contribution to the GAP book, uses an evolutionary argument to show that we should not be in the business of drawing lines in the first place. There's no law of nature that says boundaries have to be clear-cut.
Atomic Habits - PDF
نویسندگان: خلاصه: Atomic Habits is a book by James Clear that outlines a process for creating and maintaining good habits and breaking bad ones. The book explains how small changes can make a big difference in life, in the form of tiny atomic habits. It also outlines the idea of building “habit stacks” that can be used to create a structure for both personal and professional development. Clear also argues that our environment and social cues have a powerful influence on our behavior and provides tips on how to use this knowledge to our advantage.
168hours : you have more time than y ou think - PDF
نویسندگان: خلاصه: Keep track of your time, hour by hour, for a week or two so you can see how you’re actually spending your time. One woman called it “one mortifying experience” when she realized how much time she was actually spending checking Facebook while at work and how often it derailed her from getting actual things done. Figure out what your core competencies are and spend your time doing those. What are you best at? Writing? Cooking? Nurturing relationships with our significant others and children (hopefully no one is better at that than you are . . . ). Maximize your time doing those things and minimize how much time you spend doing other things. Stop doing pretend work. Lots of us spend a lot of time being busy but doing things that aren’t actually that valuable. Are you spending a lot of time doing meaningless housework, or setting up elaborate organizational systems or having long conference calls that could be finished in ten minutes if you got right on task? Whether this is in your home life or your work life, you could probably get the “have to” things done a lot faster and more efficiently than you do. I basically always spend the entire two hours of nap and quiet time at my desk, but I often end up wasting so much time trying to multi-task between screens, doing fairly unimportant busy work (spending the last $15 on a gift card or trying to clear my inbox) that I end up having to work in the evenings too and then I feel like I spend all my time “working.” Since I finished this book, I’ve made a list each day of what I needed to get done and then I just put my head down and work, not getting distracted by the other maybe-should be things that don’t matter nearly so much or could get done later at a less focused time. Decide what you can off-load. She’s an enormous fan of outsourcing as much as possible, whether it’s laundry, grocery shopping, house cleaning, lawn care, etc. She argues that Pick 2-4 hobbies or activities you want in your life. You may be saying you want to sew more or read more books or volunteer with an organization you care about or run a marathon, but then you end up squandering your free time doing really low-investment things like watching TV (which is draining and not nearly as fun as you think it is). Figure out what you want to do and then when you can fit them in and make the happen. You’ll be rejuvenated by doing the things you’ve always meant to do and the lure of the Internet and TV will be reduced. She also says one of your hobbies really should/must be exercise. When you consider doing 30 minutes, 5 days a week, that’s only 3 hours out of your entire 168 a week. You can probably (almost certainly) fit it in. I love that she doesn’t argue that it’s easy to make it happen. It takes a lot of planning and discipline to make your life look like you want it to, instead of just piddling your life away running errands, checking email, and watching TV. And she has such an engaging writing style – I think she’s somewhat similar to Gretchen Rubin, with a lot of anecdotes, discussions about what she does well herself and also where she falls short, and an ability to make all sorts of data and statistics really engaging. There are certainly things I don’t agree with her on. I’m not willing to let my housekeeping slip to barely passable to get back a small chunk of time; I’m not the world’s best housekeeper by any means and the time I spend cleaning is fairly minimal, but I don’t keep things tidy because I care what other people think – I keep the clutter to a minimum because it makes ME crazy when there are piles of things on every surface. And she doesn’t seem to enjoy cooking like I do – yes, I could probably reduce the time I spend cooking by making easier meals or doing grocery delivery, but I’m not looking to outsource those things and I like to cook. And having been in schools, I totally disagree with her hypothesis that school lunches are way improved from days of old and that it’s well-worth having your kids just buy a lunch for a few bucks (also, having just read Slim by Design, I know that people who pack their lunches tend to eat more healthily than those who buy because you pack your lunch when you’re usually not terribly hungry (after dinner or breakfast) and so you make fairly good choices, whereas if you buy lunch when you’re starving, guess what you buy? Not salad).آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
