Context, content, and epistemic transparency
We motivate the idea that presupposition is a transparent attitude. We then explain why epistemic opacity is not a serious problem for Robert Stalnaker's theory of content and conversation. We conclude with critical remarks about John Hawthorne and Ofra Magidor's alternative theory
Practical modes of presentation
The Intellectualist thesis that know-how is a kind of propositional knowledge faces a simple problem: For any proposition p, it seems that one could know p without knowing how to do the activity in question. For example, it seems that one could know that w is a way to swim even if one didn't know how to swim oneself. In this paper I argue that this "sufficiency problem" cannot be adequately addressed by appealing to practical modes of presentation.PostprintPeer reviewe
Sojourners and Settlers: Chinese Migrants in Hawaii
Among the many groups of Chinese who migrated from their ancestral homeland in the nineteenth century, none found a more favorable situation that those who came to Hawaii. Coming from South China, largely as laborers for sugar plantations and Chinese rice plantations but also as independent merchants and craftsmen, they arrived at a time when the tiny Polynesian kingdom was being drawn into an international economic, political, and cultural world.
Sojourners and Settlers traces the waves of Chinese immigration, the plantation experience, and movement into urban occupations. Important for the migrants were their close ties with indigenous Hawaiians, hundreds establishing families with Hawaiian wives. Other migrants brought Chinese wives to the islands. Though many early Chinese families lived in the section of Honolulu called "Chinatown," this was never an exclusively Chinese place of residence, and under Hawaii's relatively open pattern of ethnic relations Chinese families rapidly became dispersed throughout Honolulu.
Chinatown was, however, a nucleus for Chinese business, cultural, and organizational activities. More than two hundred organizations were formed by the migrants to provide mutual aid, to respond to discrimination under the monarchy and later under American laws, and to establish their status among other Chinese and Hawaii's multiethnic community. Professor Glick skillfully describes the organizational network in all its subtlety. He also examines the social apparatus of migrant existence: families, celebrations, newspapers, schools--in short, the way of life. Using a sociological framework, the author provides a fascinating account of the migrant settlers' transformation from villagers bound by ancestral clan and tradition into participants in a mobile, largely Westernized social order
Mothers with Children and Mothers Alone: A Comparison of Homeless Families
Researchers usually define a homeless family as those parents accompanied by minor children. This study compares a sample of homeless mothers accompanied by their children to homeless mothers who report that their children are elsewhere. While there are some differences between these two groups such as age and number of children, there are also a number of similarities. Both groups of mothers report that they rely on family members and friends as sources of instrumental support. These networks are especially useful for housing children. The findings from this investigation suggest a need for a more inclusive definition of homeless families so that services can be geared towards all families affected by a loss of stable housing
Letter from Margaret E. Glick to John Muir, 1910 Jun 29.
[1]Los Angeles, Cal.June 29, 1910.Mr. John Muir,Martinez, Cal.Dear Mr. Muir,-I thank you most sincerely for your kindness in replying to the letters from my pupils, and for writing so fully. Your letter will be kept as one of the treasures of the Sixth Grade at Hoover, with the book which they so dearly love to have read to them. The book was presented to the class by one of the pupils - the year it was published, and I gladly a[illegible]de to the request of each new class for Stickeen — it contains so many excellent lessons, - and while they follow you and the dog most anxiously - I rejoice that they are at the same time being led - step by step - out into the storm, and over the glacier!04822 [2]Our school closed June 24 - we looked most anxiously for your letter, but I told them you were a busy man and it might not come, I am so glad they are to have this surprise in the fall when we come together again, for the letter followed me to my home, and they are not to be disappointed but will know John Muir as their friend.Again thanking you, and hoping for many more stories from your pen. I am,Sincerely yours,Margaret E. Glick.0482
Recent Advances in Bacterial Amelioration of Plant Drought and Salt Stress
The recent literature indicates that plant growth-promoting bacteria (PGPB) employ a range of mechanisms to augment a plant’s ability to ameliorate salt and drought stress. These mechanisms include synthesis of auxins, especially indoleacetic acid, which directly promotes plant growth; synthesis of antioxidant enzymes such as catalase, superoxide dismutase and peroxidase, which prevents the deleterious effects of reactive oxygen species; synthesis of small molecule osmolytes, e.g., trehalose and proline, which structures the water content within plant and bacterial cells and reduces plant turgor pressure; nitrogen fixation, which directly improves plant growth; synthesis of exopolysaccharides, which protects plant cells from water loss and stabilizes soil aggregates; synthesis of antibiotics, which protects stress-debilitated plants from soil pathogens; and synthesis of the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, which lowers the level of ACC and ethylene in plants, thereby decreasing stress-induced plant senescence. Many of the reports of overcoming these plant stresses indicate that the most successful PGPB possess several of these mechanisms; however, the involvement of any particular mechanism in plant protection is nearly always inferred and not proven
The use of plant growth-promoting bacteria to prevent nematode damage to plants
Plant-parasitic nematodes have been estimated to annually cause around US $173 billion in damage to plant crops worldwide. Moreover, with global climate change, it has been suggested that the damage to crops from nematodes is likely to increase in the future. Currently, a variety of potentially dangerous and toxic chemical agents are used to limit the damage to crops by plant-parasitic nematodes. As an alternative to chemicals and a more environmentally friendly means of decreasing nematode damage to plants, researchers have begun to examine the possible use of various soil bacteria, including plant growth-promoting bacteria (PGPB). Here, the current literature on some of the major mechanisms employed by these soil bacteria is examined. It is expected that within the next 5\u201310 years, as scientists continue to elaborate the mechanisms used by these bacteria, biocontrol soil bacteria will gradually replace the use of chemicals as nematicides
