Southern Appalachia is unique among agroecological regions of the American South because of the diverse environmental conditions caused by its mountain ecology, the geographic and commercial isolation of the region, and the relative cultural autonomy of the people that live there. Those three criteria, combined with a rich agricultural history and the continuance of the homegardening tradition, make southern Appalachia an area of relatively high crop biodiversity in America. This study investigated the history and survival of traditional heirloom (...) class='Hi'>vegetable crops in western North Carolina and documented 134 heirloom varieties that were still being grown. I conducted interviews with 26 individuals from 12 counties in western North Carolina. I used a snowball sampling method to identify individuals or communities that maintained heirloom vegetable varieties, and used the “memory banking” of farmers’ knowledge as a strategy to complement the gathering of seed specimens. Most of the varieties were grown and saved by homegardeners; beans were the most numerous. Results indicate that usually only one or two individuals in a community maintained significant numbers of heirloom varieties and that many communities have lost their heirloom vegetable heritage altogether. The decline of the farming population combined with a lack of cultural continuance in family seed-saving traditions threatens the ability of communities to maintain crop biodiversity. Some of the cultivars may represent the last (small) populations of endangered varieties. (shrink)

Foodways are important in understanding the bio-cultural dynamics of crop diversity. This paper examines the example of tsukemono and their importance for heirloom vegetables. Social histories of heirlooms and tsukemono were difficult to obtain, so various sources from archives, published reports, to interviews were used to stitch together the stories of the tsukemono-heirloom relationships. The paper finds that tsukemono has provided different opportunities for heirlooms. Tsukemono can enhance the taste and flavors of heirlooms. Pickling can make the best (...) of heirloom’s unique tastes even when they are not suited for other uses. Moreover, certain tsukemono has historically been associated with important social customs like gift-giving and seasonal events. The theoretical contribution of this study is to analyze the foodway-heirloom relationships from the vantage point of the political economy of agrofood systems. It is not enough to say a particular foodway is important for heirlooms. The paper reveals the necessity of analyses that situate the heirloom- foodway relationships in the modern agrofood systems. Changes not only in agriculture but also in consumption, retail, and processing are crucial in understanding the heirloom-foodway relationship. (shrink)

For centuries, heirloom rice varieties have been grown on the terraces of the Cordillera Mountains of Luzon, Philippines, terroirs known for their significant historical, cultural, and aesthetic values. However, heritage heirloom rice farming is gradually being abandoned, mainly because of its lower productivity and the struggle of the sector to create a sustainable niche market for heirloom rice by branding its cultural, social, and nutritional values. We propose several demand-side intervention strategies for the valorization of (...) class='Hi'>heirloom rice. To support the development of a segmented marketing strategy for heritage farming, we provide evidence on urban consumers’ willingness to purchase heirloom rice. We interviewed 500 urban consumers from Metro Manila in July–August 2015, who placed a purchasing bid on a kilogram of heirloom rice. Consumers’ bids averaged PHP 72.61 kg−1, which is less than half its current market price. This explains why heirloom rice struggles to gain market share in urban markets in the Philippines. Given this bid price, we estimate a potential market size of PHP 20.3 billion that could be created for heirloom rice and tapped into by heritage farmers. Findings further indicate that women, business owners, and consumers who buy packaged rice and eat pigmented rice are willing to pay more for heirloom rice. Finally, our evidence suggests that proper information framing will be necessary to create demand and support the valorization of heirloom rice to preserve cultural heritage and in situ biodiversity of rice landraces in the Philippines.

Assess to quality diets is a basic human right. Geographical challenges and cultural traditions have contributed to the widespread malnutrition present among ethnic minorities of mountainous areas in Northwest Vietnam. Home gardens can play a role in increased diet diversity and micronutrient intakes. However, low production yields and plant diversity in ethnic home gardens have limited their contributions to household food security and nutrition. The pilot study tested a home garden intervention in weekly vegetable harvests and increasing household production (...) and consumption of diverse vegetables year-round. Food ethics issues encountered included limited access to quality food by resource-poor groups, conflicts arising from low preference and value given to some nutritious foods, limited access to information and technology for food production and consumption, each of which were addressed in the study design. The intervention includes: (1) nutrition-focused home garden training and (2) locally-adapted home garden packages consisting of garden planning, technical assistance, and high-yielding seed varieties. Twenty households from two ethnic villages in Son La province participated in the study and were randomly assigned into two groups (intervention and non-intervention). The total vegetable supply from weekly harvests of home garden produce was significantly higher in the intervention households (226 kg) compared to the non-intervention households (39 kg). The intervention group yielded 5.8 and 1.7 times more vegetables by weight and weight per area than those without the intervention. The vegetables were mainly consumed at home for both groups, but the intervention households gave more vegetables as gifts to neighbors. The intervention group cultivated a higher diversity of vegetables with a total of 42 different vegetables compared to 24 in the non-intervention group, which is reflected in an overall higher nutritional yield of vitamin A, iron, other micronutrients and phytochemicals. The home garden training significantly improved the amount, diversity and continuity of household food and nutrient supply. The home garden model is effective and could be scaled up to improve household vegetable supply and consumption, particularly in Northwest Vietnam. (shrink)

Food safety is a critical and persistent issue that challenges the sustainability of agri-food systems in Vietnam. The government has launched multiple food safety initiatives, but there is limited understanding of their contribution to changing the practices of small-scale producers and distributors. This study explores these changing practices by applying Social Practice Theory (SPT) to analyze the transitions in everyday routines of small-scale vegetable producers while being embedded in socio-institutional contexts of agri-food system transitions. We conducted semi-structured interviews and (...) survey with small-scale food producers and distributors in Hanoi, Vietnam to examine the transitions in production and post-production practices over the last 20 years and the intersection between smallholding practices and cross-level dynamics. The study revealed, contrary to some common perceptions, that smallholder producers are transitioning towards food safety, with the use of more bio-pesticides and eco-friendly pest control methods. The smallholders also reproduce a variety of (sustainable) intensification practices, including crop rotation, organic fertilization, and soil cultivation, to sustain soil fertility and save labor. However, there are no clear patterns of change for post-production practices, although they have been diversifying under the impacts of urbanization. The findings highlight the interplay of food safety, labor, and soil environment in shaping the transitions of smallholder practices. We suggest that success in improving safety in production practices is feasible, but that this requires more thorough interventions in distribution and consumption practices to transform the food systems at large.

Ford, Norman In 1972 Brian Jennett and Fred Plum recommended the term 'persistent vegetative state' to describe a state of continuing 'wakefulness without awareness', which can follow a variety of severe insults to the brain. Their description of the syndrome has stood the test of time, but PVS continues to be a source of medical, legal, and ethical debate.

Recent neuroscientific evidence brings into question the conclusion that all aspects of consciousness are gone in patients who have descended into a persistent vegetative state (PVS). Here we summarize the evidence from human brain imaging as well as neurological damage in animals and humans suggesting that some form of consciousness can survive brain damage that commonly causes PVS. We also raise the issue that neuroscientific evidence indicates that raw emotional feelings (primary-process affects) can exist without any cognitive awareness of those (...) feelings. Likewise, the basic brain mechanisms for thirst and hunger exist in brain regions typically not damaged by PVS. If affective feelings can exist without cognitive awareness of those feelings, then it is possible that the instinctual emotional actions and pain "reflexes" often exhibited by PVS patients may indicate some level of mentality remaining in PVS patients. Indeed, it is possible such raw affective feelings are intensified when PVS patients are removed from life-supports. They may still experience a variety of primary-process affective states that could constitute forms of suffering. If so, withdrawal of life-support may violate the principle of nonmaleficence and be tantamount to inflicting inadvertent "cruel and unusual punishment" on patients whose potential distress, during the process of dying, needs to be considered in ethical decision-making about how such individuals should be treated, especially when their lives are ended by termination of life-supports. Medical wisdom may dictate the use of more rapid pharmacological forms of euthanasia that minimize distress than the de facto euthanasia of life-support termination that may lead to excruciating feelings of pure thirst and other negative affective feelings in the absence of any reflective awareness.

The study's purpose was to estimate the variety of foods consumed within standard and ethnic food categories by three groups of women between 18 and 35 years of age. Foreign-born Chinese women [N = 21], Chinese-American women [N = 20] and white American women [N = 23] kept 4-day food records, after instruction. Analysis of variance showed that the mean number of different foods consumed by the foreign-born Chinese was significantly [p < 0.05] lower than those eaten by the other (...) two groups for breads/cereals, dairy products, ethnic foods, fats, meats, sweets/sugars, and vegetable categories. White American women consumed significantly more dairy products and legumes/nuts than either of the groups of Chinese women. Diets of the Chinese-American women were more nutrient dense than those of the women in the other groups, containing significantly more energy, riboflavin, iron, folacin, and calcium than those of the foreign-born Chinese women. The percentage of kilocalories derived from fat [33–34%] did not differ among groups. 95% of foreign-born and 85% of Chinese-American women affirmed their ethnic identification by consuming foods belonging to Chinese cuisine; whereas, the percentage [30%] of white American women selecting Chinese food was significantly lower. Mexican and Italian foods were selected by significantly more white and Chinese-American women than by foreign-born Chinese women. Approximately 20% of both groups of Chinese women, but 49% of white American subjects, ate Japanese food. Chinese-American women retained a preference for Chinese food, similar to that of the foreign-born Chinese women. However, the Chinese-American women consumed cheeses, legumes, raw vegetables in salads, and foods from Italian and Mexican cuisines, indicating their acceptance of foods commonly consumed by white American women. Dietary acculturation among the Chinese-American women improved their diets over those of the foreign-born Chinese women and these results support the theory that consumption of a greater variety of foods increases nutrient density of diets.

Reciprocity and redistribution economies are often used by low-income households to increase access to food, adequate diets, and food security. A United States study of two high poverty rural counties and two low-income urban neighborhoods reveal poor urban households are more likely to access food through the redistribution economy than poor rural households. Reciprocal nonmarket food exchanges occur more frequently in low-income rural households studied compared to low-income urban ones. The rural low-income purposeful sample was significantly more likely to give (...) food to family, friends, and neighbors and obtain food such as fish, meat, and garden produce from friends and family compared to the urban low-income group. Further, 58% of the low-income rural group had access to garden produce while only 23% of the low-income urban group reported access. In a rural random sample of the whole population in the two high poverty counties access to garden produce increased chances of attaining recommended vegetable and fruit servings controlling for income, education, and age. Access to a garden also significantly increased the variety of fruits and vegetables in diets. (shrink)

Arthur G. Tansley never accepted Frederic E. Clements’ view that succession is a developmental process whose final stage, the climax formation, is determined primarily by regional climate and that all other types of vegetation are some kind of successional stage or arrested successional stage. Tansley was convinced that in a given region a variety of environmental factors could produce different kinds of climax formations. At the heart of their dispute was Clements’ organicist view of succession, i.e., the formation was a (...) complex organism with an ontogeny and phylogeny. As early as 1905, Tansley offered an alternative to Clements’ complex organism, the quasi-organism, but Clements in private and public rejected this compromise. Tansley and other plant ecologists continued to criticize Clements’ theories for the next 20 years, but with no impact on Clements. John Phillips, a South African plant ecologist who was a follower of Clements, published a series of papers in 1934 and 1935 defending Clementsian ecology. These papers were triggered by the publication of a letter by another ecologist working in Africa who claimed that there was a strong correlation between soils and various kinds of climax vegetation, which was contrary to what was predicted by Phillips and Clements. In 1935, Tansley published an attack on Phillips and Clements and their developmental theory of succession. In it, he proposed the concept of the ecosystem as a way to get around Clements’ monoclimax theory by making the physical environment (e.g., soil chemistry, soil texture, soil moisture) as important a factor as climate, plants and other organisms in determining the composition and characteristics of ecological entities, i.e., ecosystems. Tansley’s ecosystem concept quickly replaced Clements’ monoclimax theory as a dominant paradigm in ecology. (shrink)

Agrifood scholars have long investigated the relationship between farm size and a wide variety of social and ecological outcomes. Yet neither this scholarship nor the extensive research on farmworkers has addressed the relationship between farm size and job quality for hired workers. Moreover, although this question has not been systematically investigated, many advocates, popular food writers, and documentaries appear to have the answer—portraying precarious work as common on large farms and nonexistent on small farms. In this paper, we take on (...) this question by describing and explaining the relationship between farm size and job quality for hired farm workers. To do so, we draw on data from two independently conducted, mixed-methods case studies—organic fruit and vegetable production in California, and dairy farming in Wisconsin—each of which offers a different set of insights into the farm size-job quality relationship. In both cases, larger farms fared better than or no worse than their smaller-scale counterparts for most job quality metrics investigated, though many of the advantages of working on large farms accrue disproportionately to white, U.S.-born workers. We explain that these patterns stem from economies of scale, industrialization, firm size itself, the dominant class identities and aspirations of farmers and their peers, as well as farmers’ and immigrant workers’ fears of immigration enforcement.

Following the implementation of the North American Free Trade Agreement (NAFTA), Mexican farmers altered their livelihood strategies to respond to changing market incentives. While many commercial farmers responded to falling maize prices brought on by NAFTA by shifting into the production of vegetables for export, the coping strategies of low-income farmers have been varied, from diversifying income sources through off-farm employment, to migration, to searching for niche markets for new or added-value products. In the Totonocan region of the state of (...) Veracruz, Mexico, many farmers who can no longer earn sufficient income from the sale of maize grain are turning to a byproduct of maize to generate income. The commercialization of totomoxtle, or maize husks, for domestic and international markets has not only enabled farmers to continue to profit from maize production, but it has also encouraged farmers to utilize and conserve criollo maize varieties that serve as important reservoirs of genetic diversity. Moreover, the growing importance of totomoxtle in livelihood strategies has caused some farmers to alter their maize management, selecting for better quality husks rather than for grain production. The purpose of this paper is to understand both the broad impact of NAFTA on the local agricultural economy and its more specific effects on the management of maize in the Zona Totonaca. Participation in international trade can lead to unexpected outcomes, in some cases creating new values for goods with a long history of local consumption. Commercialization of maize husks is likely to be only a temporary solution for the relief of rural poverty. Given the volatility of international markets, the long-term welfare of farmers may depend on the development of more diversified production strategies. (shrink)

In this article, I follow the evolving visual form of the plant illustrations produced by the 17th-century physician and microscopist Nehemiah Grew. I trace the changing appearance of a variety of magnified plants throughout the course of their manifestation in illustration: beginning with their unsteady earliest appearance in 1672 in the publication The Anatomy of Vegetables Begun, into their reworking in the popular French translation, which was reissued and reprinted multiple times, and finally to Grew's magnum opus a decade later, (...) The Anatomy of Plants (1682). In addition to addressing the epistemic significance of these shifts in style, I also consider the importance of the translation process for the refining of Grew's ideas. (shrink)

A key philosophical feature of Peter Jackson’s film interpretation of J.R.R. Tolkien’s The Lord of the Rings is its use of fantasy to inspire a “recovery” of the actual or, in other words, a reawakening to the beauty of nature and the many possible ways of living in healthier ecological relation to the world. Though none of these ways is perfectly achieved, this pluralistic view is demonstrated in the various lifeways of Hobbits, Elves, Men, and Ents. All of the positive (...) relationships embodied in the films—to trees, mountains, horses, and vegetable gardens—involve loving care and attention, receiving nourishment and livelihood without instrumentalization, or reducing nature to mere resource. The films also vividly display a variety of ugly and destructive ways of using the land to accrue power and wealth. These noxious ways, specifically because they actively destroy the lands that they use, always need more. They will thus eventually annihilate the beautiful ways of being if they are not actively resisted. Some of those who would rather be tending their own trees, gardens, or horses or even wandering in the wild forests must therefore turn their attention to struggle and resistance instead. This is a struggle full of grief, and at times even verging on despair, but it is marked by the refusal to give up hope. Indeed, what Jackson and Tolkien have to say about hope is as important in responding to the ecological crisis as anything they have to say about nature, inasmuch as they help to remind us that even in our own times, “there is still hope.”.

"Biophilia" is the term coined by Edward O. Wilson to describe what he believes is humanity's innate affinity for the natural world. In his landmark book Biophilia, he examined how our tendency to focus on life and lifelike processes might be a biologically based need, integral to our development as individuals and as a species. That idea has caught the imagination of diverse thinkers. The Biophilia Hypothesis brings together the views of some of the most creative scientists of our time, (...) each attempting to amplify and refine the concept of biophilia. The variety of perspectives -- psychological, biological, cultural, symbolic, and aesthetic -- frame the theoretical issues by presenting empirical evidence that supports or refutes the hypothesis. Numerous examples illustrate the idea that biophilia and its converse, biophobia, have a genetic component: fear, and even full-blown phobias of snakes and spiders are quick to develop with very little negative reinforcement, while more threatening modern artifacts -- knives, guns, automobiles -- rarely elicit such a response people find trees that are climbable and have a broad, umbrella-like canopy more attractive than trees without these characteristics people would rather look at water, green vegetation, or flowers than built structures of glass and concrete The biophilia hypothesis, if substantiated, provides a powerful argument for the conservation of biological diversity. More important, it implies serious consequences for our well-being as society becomes further estranged from the natural world. Relentless environmental destruction could have a significant impact on our quality of life, not just materially but psychologically and even spiritually. (shrink)

Chaplains who serve in a clinical context often minister to patients representing a wide variety of faiths. In order to offer the best pastoral care possible, the chaplain should first possess a set of personal theological convictions as a foundation for ministry. Second, he or she needs to be sensitive to the beliefs and practices of the patients. Third, it is vital to develop a relationship of acceptance and trust not only with patients under their care, but also with family (...) members and caregivers as well. At times, situations will arise that are purely religious or theological. In a clinical setting, however, the questions and problems that arise more often are both theological and ethical. It is beneficial for the chaplain to be involved in an ethics committee, where the specifics of each case can be discussed, and staff can offer counsel to patients and their families. This study examines issues that chaplains face at the bedside, such as terminal care, life-prolonging treatments, dementia, persistent vegetative state, and euthanasia/assisted suicide. We will discover that those who are involved in clinical pastoral ministry will be called upon to be a comforter, mediator, educator, ethicist, and counselor. (shrink)

This article examines crop varietal standardization in the United States. Numerous committees formed in the early twentieth century to address the problem of nomenclatural rules in the horticultural and agricultural industries. Making shared reference to a varietal name proved a difficult proposition for seed-borne crops because plant conformity tended to change in the hands of different breeders. Moreover, scientific and commercial opinions diverged on the value of deviations within crop varieties. I review the function of descriptive difference in the (...) seed trade and in the framework of evolutionary theory before examining the institutional history of varietal standardization. Pimento peppers are used to represent how vegetables were treated differently than cereals. Lack of stability within a popular pimento variety caused problems for food packers in middle Georgia, which public breeders addressed by releasing new peppers. To conclude, the article questions the role of taxonomy in intellectual property, as breeding history and yield became defining attributes for making varietal distinctions. (shrink)

A survey of high school student expectations on biotechnology was made, including the information, where it came from, how information resources influence their scientific thoughts.

Agricultural intensification, now commonly referred to as sustainable intensification, is presented in development discourse as a key means to simultaneously improve food security and reduce rural poverty without harming the environment. Taking a village in Laos as a case study, we show how government agencies and farmers could perceive the idea of agricultural intensification differently. The study illustrates how farmers with the opportunities for groundwater use typically choose to grow vegetables and high valued cash crops rather than intensify rice production. (...) This contrasts with government and donor supported efforts to promote rice intensification as a means to increase food security and reduce rural poverty. The article’s main message is that farmers’ differing strategies are related to a variety of household characteristics and that farmers’ strategies should be central to the current discussion on sustainable intensification.

The present study aims to investigate the level of health self-reliance among Lao women in the Lao People's Democratic Republic (PDR) and to enhance their potential for health self-reliance by means of research and development. A variety of qualitative techniques were employed, such as brainstorming, focus groups, in-depth interviews, and observation. The target groups include experts from the Ministry of Public Health, leaders of Lao women, representatives of Lao women in Vientiane Capital, academics with relevant experience in Lao Women's Federation (...) agencies, and representatives of the agency in charge of the project on promoting Laos mothers. It was found that: 1) Lao women in the Lao PDR have normal health and self-reliance; they avoid smoking, eat fermented foods and seasonal fruits and vegetables, and occasionally engage in aerobic and running exercise. Regarding reliance on one's health in the event of illness, research is being done to better understand different ailments. 2) The outcomes of transforming health behaviors and planning seven activities to enhance the health self-reliance potential of Lao women in the Lao PDR.

In lieu of an abstract, here is a brief excerpt of the content:Breathing with Denise LevertovNoëlle Batt (bio)The BreathingAn absolutepatience.Trees standup to their knees infog. The fogslowly flowsuphill.Whitecobwebs, the grassleaning where deerhave looked for apples.The woodsfrom brook to wherethe top of the hill looksover the fog, send upnot one bird.So absolute, it isno other thanhappiness itself, a breathingtoo quiet to hear.–Denise LevertovI propose to share this poem, "The Breathing," by Denise Levertov, with the readers of SubStance as a moment of (...) calm, an antidote to violence and pain, and a gesture of hope in the future relations between humans and the many creatures of the vegetal and animal world.What is remarkable in this imaginary landscape sketched by Levertov is the peacefulness of the scene which is mostly due to the absence of movement, the absence of action performed in praesentia between the first and the last word of the poem. And since we know that poets are marvelous craftsmen and craftswomen of language, we shall look for the cause to this effect in the poetic language and shall find it in the subtly modulated use (or non-use) of verbs in the poem, a different kind of use in each sentence, yet, converging to the same effect. And since verbs are also the main markers of time in language, the poem appears in the literal sense, as a verbal, a literary "still life." [End Page 160]The first sentence strikes a strong blow since the verb is quite simply omitted in it. The sentence is a nominal clause: "An absolute/ patience."In the second sentence, "Trees stand/ up to their knees in/ fog," we find a static verb "to stand" and the personification of the trees clearly establishes that they might have moved, but they have not; they stand wrapped in the fog up to "their knees," i.e., between a quarter and a fifth of their trunks.In the third sentence, something moves: "The fog/ slowly flows/ uphill." But there is something contradictory in the fact of flowing up. Usually, rivers or brooks flow down. Flowing up, then, implies a difficulty to flow and consequently a slowing down of the rhythm of the flow which is here expressed by the adverb "slowly"; the adverb seems here all the more congenial to the flowing in that the two words are linked by a strong paronomastic effect: slowly flows, set in the two /s/, one at the beginning of slowly, the other at the end of flows: slowly flows.The fourth sentence is characterized by still another pattern: "White/ cobwebs. The grass/leaning where deer/have looked for apples." We now face the result of two past actions, actions that were performed before the scene that the poem invites us to contemplate was composed. In effect, the "white cobwebs" have been woven by the spiders at a previous moment, and they even had time to be colored in white by the drops of the humid fog. And "the grass leaning where deer have looked for apples" tells us that deer were here earlier, looking for food, but they no longer are, and what signals their former presence is a tenuous detail: the inclination of the grass, bent by their walking on it and searching through it, remaining bent for a little while after their passage. And to achieve her verbal strategy, Levertov even suppresses the auxiliary which might have been here. We read "the grass leaning" with a lonely present participle, and not "the grass is leaning."Another interesting grammatical event happens in the fifth sentence: "The woods/ from brook to where/ the top of the hill looks/ over the fog, send up/ not one bird." The first verb is a verb of perception ("to look") and not a verb of action. But the second verb is a verb of action ("to send up"), which is used in a quite unusual variety of the verbal negative form since instead of having the negative adverb attached to the verb (don't send up), we have an affirmative use of the verb ("send...

Recently published work showed that members of the PAQR protein family are activated by cell membrane rigidity and contribute to our ability to eat a wide variety of diets. Cell membranes are primarily composed of phospholipids containing dietarily obtained fatty acids, which poses a challenge to membrane properties because diets can vary greatly in their fatty acid composition and could impart opposite properties to the cellular membranes. In particular, saturated fatty acids (SFAs) can pack tightly and form rigid membranes (like (...) butter at room temperature) while unsaturated fatty acids (UFAs) form more fluid membranes (like vegetable oils). Proteins of the PAQR protein family, characterized by the presence of seven transmembrane domains and a cytosolic N‐terminus, contribute to membrane homeostasis in bacteria, yeasts, and animals. These proteins respond to membrane rigidity by stimulating fatty acid desaturation and incorporation of UFAs into phospholipids and explain the ability of animals to thrive on diets with widely varied fat composition.

This Dissertation argues for a care-centrically grounded account of relational personhood and widely realized diachronic personal identity. The moral distinction between persons and non-persons is arguably one of the most salient ethical lines we can draw since many of our most fundamental rights are delineated via the bounds of personhood. The problem with drawing such morally salient lines is that the orthodox, rationalistic definition of personhood, which is widespread within philosophical, medical, and colloquial spheres, excludes, and thereby de-personifies, a large (...) number and a great variety of human beings such as neonates, young children, the elderly who suffer from dementia, individuals with severe cognitive disabilities, and patients in vegetative states. The reconceptualization of personhood necessary for a more inclusive definition ought to originate with an appropriate moral grounding. To this end, this Dissertation grounds the notion of personhood in the care ethical sphere, thereby emphasizing the role of care relations in the maintenance of the moral consideration of vulnerable individuals. This Dissertation argues that grounding the concept of a person in care relations entails a relational account of personhood, which, along with the insights of the Extended Mind and Social Manifestation Theses, leads to an extended and externalized understanding of diachronic identity, which allows fragile people to be held in their personal identities even if they themselves lack the capacities usually associated with moral personhood. As we trace a person’s identity through time, we track the various relational properties, which constitute personal narratives and thus act as a glue that binds such dynamic and often unique properties into stable, trackable narratives. Since care relations are morally relevant on a care-centric account of personhood, what is lost in cases where such care relating ceases is not merely of sentimental value, but of great moral importance as well. Morally meaningful care relations are not replaceable, and, by extension, neither are the narratives that are constituted by such unique and irreplaceable instances of relating. This Dissertation argues that the constitutive care relational nature of personal narratives makes such narratives irreplaceable and is precisely what makes persons so morally precious. (shrink)

Climate change is a threat to food system stability, with small islands particularly vulnerable to extreme weather events. In Puerto Rico, a diminished agricultural sector and resulting food import dependence have been implicated in reduced diet quality, rural impoverishment, and periodic food insecurity during natural disasters. In contrast, smallholder farmers in Puerto Rico serve as cultural emblems of self-sufficient food production, providing fresh foods to local communities in an informal economy and leveraging traditional knowledge systems to manage varying ecological and (...) climatic constraints. The current mixed methods study sought to document this expertise and employed a questionnaire and narrative interviewing in a purposeful sample of 30 smallholder farmers after Hurricane María to identify experiences in post-disaster food access and agricultural recovery and reveal underlying socioecological knowledge that may contribute to a more climate resilient food system in Puerto Rico. Although the hurricane resulted in significant damages, farmers contributed to post-disaster food access by sharing a variety of surviving fruits, vegetables, and root crops among community members. Practices such as crop diversification, seed banking, and soil conservation were identified as climate resilient farm management strategies, and smallholder farmer networks were discussed as a promising solution to amass resources and bolster agricultural productivity. These recommendations were shared in a narrative highlighting socioecological identity, self-sufficiency, community and cultural heritage, and collaborative agency as integral to agricultural resilience. Efforts to promote climate resilience in Puerto Rico must leverage smallholder farmers’ socioecological expertise to reclaim a more equitable, sustainable, and community-owned food system. (shrink)

Meat production in South Africa is on an increasing trend. In South Africa rising wealth, urbanisation and a growing middle class means South Africans are eating more processed and high-protein foods, especially meat and dairy products. These foods are more land- and water-intensive than fruit, vegetable and grain crops, and further stress existing resources. Traditional agricultural farms cannot keep up with the increasing demand for animal products and these farms are being replaced with concentrated animal feeding operations. There are (...) a wide variety of problems caused by intensive livestock production. The concerns regarding factory farming in South Africa are social issues affecting food security, health concerns, environmental concerns and ethical concerns. In order to ensure food security in future we need to consider these concerns and support more sustainable systems to produce our food. Animal agriculture, like many other industries, works on the principles of supply and demand. By decreasing the demand for these products, we can decrease their production. Individuals can do this by becoming vegetarian or vegan, but also by simply cutting down one’s consumption of meat, eggs, and milk produced in intensive livestock farms. Less meat would be produced, and there would be less harm to local communities, lower risk of zoonotic disease outbreaks, fewer greenhouse gas emissions, less land degradation and decrease of biodiversity, less damage to our water supplies and fewer animals living lives of suffering in factory farms.

The purpose of this article is to compare several street typologies (distributed from center to suburb) in Tirana, Albania while taking into consideration pedestrian behavior on these pathways. The streets "Myslym Shyri," "Bllok," "Kombinat" (an extension of Kavaja's Street), and "Ana Komnena" (formerly "Fusha e Aviacionit") will be the primary focus of this study. The following variables will be taken into account such as pedestrian behaviors, street identity, dissatisfaction, walking distance when shifting to another zone, effects of greenery on pedestrians, (...) time spent, points of interest, frequency, pavement quality, preferred walking periods, gathering places, utilization of benches, ambulant sellers, impact of vegetation and greenery, water basins, preference for public transportation, and road signs. Direct observations and a questionnaire will be used to determine the accurate information. The study should provide recommendations as guidance for municipalities and stakeholders to better understand the behavior of pedestrians in Tirana’s context. The streets that pedestrians frequent the most include the "Bllok" area and "Myslym Shyri" Street. The pedestrian resident population on "Myslym Shyri" street, which is dominated by people of all ages, including children, youth, and the elderly, has a slight advantage over the "Bllok" neighborhood.

Meanwhile, the pedestrians on Kombinati’s street suffer a little bit more because of the traffic congestion and vehicle pollution. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Time and History in Alois Riegl's Theory of PerceptionMichael GubserIn an early essay, the Austrian art historian Alois Riegl (1858–1905), a pioneer of the modern discipline of art history, linked the creation of the zodiac images in calendar art to the designation of constellations in the heavens.1 Ancient calendar artists observed the motion of stars across the night sky and attempted to map them into recognizable patterns representing specific (...) temporal periods. Their efforts inscribed the cyclical temporality of the heavens into the images of the ancient calendar. This inherent temporality came to characterize all art forms in Riegl's work; his choice of calendar art as his earliest research topic heralded a career-long interest in the connection between temporality and artistic form. Art objects, he believed, were temporal as well as spatial. Just as the light from constellations reflected a deep history, artworks illuminated the passage of time by visually re-presenting the perceptual world of past eras.Riegl's work has garnered attention in recent decades among art historians and non–art historians alike. This interest is due in part to the renewed concern for disciplinary origins that art history, like other fields, has experienced in the wake of poststructuralist critiques. Scholars outside of art history have taken note of his work because of its broad scope and relevance for the study of historiography and perception; Riegl's work provides models for linking the analysis of specific artworks with a history of perception, exploring the relationship between monuments and memory, and analyzing the nature of visual modernity. Interest in Riegl also stems from his acknowledged impact on such preeminent philosophers and historical theorists as Erwin Panofsky, Paul Feyerabend, Gilles Deleuze, Fèlix Guattari, and above all Walter [End Page 451] Benjamin.2 Figures as varied as Georg Lukács, Karl Mannheim, Walter Gropius, and Mikhail Bakhtin have cited his work favorably.3 Riegl is perhaps best known for his attempts to dismantle the hierarchy of high and low art, his attack on the preeminence of classical aesthetic ideals, and his effort to construct a universal history of style. The combination of these commitments led him to consider European and non-European craft genres that fell outside conventional definitions of art. In books such as Problems of Style, Late Roman Art Industry, and The Group Portraiture of Holland, Riegl examined the high arts, decorative arts, and manufactured artifacts alike, gleaning insights into the structure of an era's perception from close descriptive analyses of its artwork.4 In Problems of Style, Riegl traced the development of ancient vegetal decorative motifs toward their fulfillment in the naturalized tendrils and acanthus leaves of Greek ornament. A single, universal development encompassed seemingly distinct motivic forms, and creative innovation was driven by an inner formal logic. Similarly, Late Roman Art Industry, the [End Page 452] epoch-making work that Walter Benjamin described as a revolution in art historical method,5 traced the gradual development of space as an object of artistic concern in the late Roman Empire. In this volume, Riegl explored his controversial notion of the Kunstwollen, or artistic will, which asserted art's autonomy on the basis of a formal creative volition internal to artworks.6 Finally, The Group Portraiture of Holland documented the emergence and decline of a "typically Hollandish painting" emphasizing space and attention.7Riegl scholars have frequently attempted to situate his art history within a variety of philosophical traditions, an effort complicated by Riegl's limited citation of sources. Several scholars have linked Riegl's historical vision with the embattled tradition of Hegelian philosophy. Riegl's teleology; his stress on the unified, internal, and purposive development of art; his notion of art as mind overcoming material; and even his emphasis on the role of the viewer in art all have a distinctly Hegelian resonance. Wolfgang Kemp fits Riegl squarely within a late-nineteenth-century Hegelian revival,8 Michael Podro incorporates him within a Hegelian critical tradition of art history that spanned the nineteenth and early twentieth centuries,9 and Michael Ann Holly posits a clear trajectory, linking Kant and Hegel with Riegl and Panofsky.10Others, however, just as firmly reject this...

In general, our concepts take shape by way of contrast. Geoffrey Lloyd commented almost 60 years ago on “the remarkable prevalence of theories based on opposition in so many societies at different stages of technological development,” and he illustrated in detail the tendency of the ancient Greeks to think in binary pairs. One fundamental distinction, found in a wide variety of cultures, is that between human beings and other animals, or, more simply, between humans and animals, which serves to identify, (...) define, and privilege our own nature as a species. Classical Greek classifications do not invariably take the form of simple polarities, to be sure; thus, one might locate humanity within the ternary taxonomy of plants, animals, and human beings, or in the alternative triad of animals, human beings, and gods, where humanity occupies the middle tier. But whatever the larger paradigm, the essential differential between human beings and other animals was the presence or absence of reason. Plants, in Aristotle’s schema, possess a vegetative soul, which is to say, the capacity to grow and develop; animals have, in addition, the faculty of perception; but human beings are unique in possessing, in addition to these two parts of the psyche, reason or, in Greek, logos, a trait that we share with the gods (they differ from us in being immortal).

MEDIEVAL PHILOSOPHERS HAD NO SINGLE RESPONSE to the difficult question of how souls are related to the bodies they animate. In this respect, the theory of psychological inherence advanced by the noted Parisian philosopher John Buridan is a case in point. Buridan offers different accounts of the soul-body relation, depending upon which of two main varieties of natural, animate substance he is explaining. In the case of human beings, he defends a version of immanent dualism: the thesis that the (...) soul is an immaterial, everlasting, and created entity, actually inhering in each and every body it animates, and thus numerically many. But when his explanandum is the relation between nonhuman animal or plant souls and their bodies, Buridan is a materialist; that is, he regards the sensitive and vegetative souls of such creatures as no more than collections of material, extended powers exhaustively defined by their biological functions, and hence as corruptible as the particular arrangements of matter they happen to animate.

Establishing healthy dietary habits in childhood is crucial in preventing long-term repercussions, as a lack of dietary variety in childhood leads to enduring impacts on both physical and cognitive health. Poor conceptual knowledge about food has recently been shown to be a driving factor of food rejection. The majority of studies that have investigated the development of food knowledge along with food rejection have mainly focused on one subtype of conceptual knowledge about food, namely taxonomic categories (e.g., vegetables or meat). (...) However, taxonomic categorization is not the only way to understand the food domain. We also heavily rely on other conceptual structures, namely thematic associations, in which objects are grouped because they share spatial-temporal properties or exhibit a complementary relationship (e.g., soft-boiled egg and soldiers). We rely on such thematic associations between food items, which may not fall into the same taxon, to determine the acceptability of food combinations. However, the development of children's ability to master these relations has not been systematically investigated, nor alongside the phenomenon of food rejection. The present research aims to fill this gap by investigating (i) the development of conceptual food knowledge (both taxonomic and thematic) and (ii) the putative relationship between children's food rejection (as measured by the Child Food Rejection Scale) and both thematic and taxonomic food knowledge. A proportional (A:B::C:?) analogy task, with a choice between taxonomic (i.e., bread and pasta) and thematic (i.e., bread and butter) food associates, was conducted on children between 3 and 7-years-old (n= 85). The children were systematically presented with either a thematic or taxonomic food base pair (A:B) and then asked to extend the example type of relation to select the respective thematic or taxonomic match to the target (C:?). Our results revealed, for the first time, that increased levels of food rejection were significantly predictive of poorer food identification and decreased thematic understanding. These findings entitle us to hypothesize that knowledge-based food education programs to foster dietary variety in young children, should not only aim to improve taxonomic understanding of food, but also thematic relations.

Over the last half-century, quality control standards have had the perverse effect of restricting the circulation of non-commercially bred vegetable cultivars in Britain. Recent European and British legislation attempts to compensate for this loss of agrodiversity by relaxing genetic purity standards and the cost of seed marketing for designated “Amateur” and “Conservation” varieties. Drawing on fieldwork conducted at a British allotment site, this article cautions against bringing genetically heterogeneous cultivars into the commercial sphere. Such a move may intensify (...) the horticultural “deskilling” of British allotment gardeners, who have come to rely on commercial seed catalogs as sources of germplasm and knowledge. Horticultural deskilling also entails the delegation of seed selection activities to professional breeders and the potential loss of agrodiversity. The activities of dedicated seed savers who save and circulate the seed of genetically heterogeneous “heritage” varieties, in a manner similar to the management of landraces in the global South, may provide a better model for attempts to safeguard vegetable diversity in the global North.

Arthur G. Tansley never accepted Frederic E. Clements’ view that succession is a developmental process whose final stage, the climax formation, is determined primarily by regional climate and that all other types of vegetation are some kind of successional stage or arrested successional stage. Tansley was convinced that in a given region a variety of environmental factors could produce different kinds of climax formations. At the heart of their dispute was Clements’ organicist view of succession, i.e., the formation was a (...) complex organism with an ontogeny and phylogeny. As early as 1905, Tansley offered an alternative to Clements’ complex organism, the quasi-organism, but Clements in private and public rejected this compromise. Tansley and other plant ecologists continued to criticize Clements’ theories for the next 20 years, but with no impact on Clements. John Phillips, a South African plant ecologist who was a follower of Clements, published a series of papers in 1934 and 1935 defending Clementsian ecology. These papers were triggered by the publication of a letter by another ecologist working in Africa who claimed that there was a strong correlation between soils and various kinds of climax vegetation, which was contrary to what was predicted by Phillips and Clements. In 1935, Tansley published an attack on Phillips and Clements and their developmental theory of succession. In it, he proposed the concept of the ecosystem as a way to get around Clements’ monoclimax theory by making the physical environment (e.g., soil chemistry, soil texture, soil moisture) as important a factor as climate, plants and other organisms in determining the composition and characteristics of ecological entities, i.e., ecosystems. Tansley’s ecosystem concept quickly replaced Clements’ monoclimax theory as a dominant paradigm in ecology. (shrink)

The demand for organs prompted the first use of elective ventilation in the UK in the 1990s. Recently the shortfall in supply of organs has once again prompted calls for elective ventilation to be instituted even in patients who are not brain dead. This paper proposes that the term ‘elective’ ventilation is a misnomer and the term non-therapeutic ventilation (NTV) should be used instead. It is further argued that the practice of NTV in cases of severe stroke is unethical and (...) has the potential of causing a variety of harms to the patient, their relatives, the healthcare professionals working in transplant teams and this may result in a backlash of reductions in the number of organ donations.

In our paper we investigate a difficulty arising when one tries to reconsiliateessentialis t’s thinking with classification practice in the biological sciences. The article outlinessome varieties of essentialism with particular attention to the version defended by Brian Ellis. Weunderline the basic difference: Ellis thinks that essentialism is not a viable position in biology dueto its incompatibility with biological typology and other essentialists think that these two elementscan be reconciled. However, both parties have in common metaphysical starting point and theylack (...) explicit track of methodological procedures. Methodological inquiry involves less demandingassumptions than metaphysical, and therefore it is justified to analyse abovementioned discrepancy between Ellis and other essentialist in this context. We do it by bottom-up investigation whichfocuses on the practice of taxonomists in the particular field of biology. A case study helps us todiscover four characteristics of biological typology practice: impossibility of algorithmization,relativity, subjectivity and conventionality. These features prove non-realistic and therefore anti-essentialistic character of biological classification. We conclude by saying that any essentialismrelated to the notion of biological kind cannot be regarded as justified by scientific enterprise of creating typologies. (shrink)

How the various things that are said to have meaning—purpose, natural signs, linguistic signs, perceptions, and thoughts—are related to one another.

Several authors have recently suggested that moral factors and norms `encroach' on the epistemic, and because of salient parallels to pragmatic encroachment views in epistemology, these suggestions have been dubbed `moral encroachment views'. This paper distinguishes between variants of the moral encroachment thesis, pointing out how they address different problems, are motivated by different considerations, and are not all subject to the same objections. It also explores how the family of moral encroachment views compare to classical pragmatic encroachment accounts.

Recent work on consciousness has featured a number of debates on the existence and character of controversial types of phenomenal experience. Perhaps the best-known is the debate over the existence of a sui generis, irreducible cognitive phenomenology – a phenomenology proper to thought. Another concerns the existence of a sui generis phenomenology of agency. Such debates bring up a more general question: how many types of sui generis, irreducible, basic, primitive phenomenology do we have to posit to just be able (...) to describe the stream of consciousness? This book offers a first general attempt to answer this question in contemporary philosophy. It develops a unified framework for systematically addressing this question and applies it to six controversial types of phenomenal experience, namely, those associated with thought and judgment, will and agency, pure apprehension, emotion, moral thought and experience, and the experience of freedom.

I know, for the most part, what I think, want, and intend, and what my sensations are. In addition, I know a great deal about the world around me. I also sometimes know what goes on in other people's minds. Each of these three kinds of empirical knowledge has its distinctive characteristics. What I know about the contents of my own mind I generally know without investigation or appeal to evidence. There are exceptions, but the primacy of unmediated self-knowledge is (...) attested by the fact that we distrust the exceptions until they can be reconciled with the unmediated. My knowledge of the world outside of myself, on the other hand, depends on the functioning of my sense organs, and this causal dependence on the senses makes my beliefs about the world of nature open to a sort of uncertainty that arises only rarely in the case of beliefs about my own states of mind. Many of my simple perceptions of what is going on in the world are not based on further evidence; my perceptual beliefs are simply caused directly by the events and objects around me. But my knowledge of the propositional contents of other minds is never immediate in this sense; I would have no access to what others think and value if I could not note their behaviour. (shrink)

Logical pluralism is the view that different logics are equally appropriate, or equally correct. Logical relativism is a pluralism according to which validity and logical consequence are relative to something. Stewart Shapiro explores various such views. He argues that the question of meaning shift is itself context-sensitive and interest-relative.

Gareth Evans, one of the most brilliant philosophers of his generation, died in 1980 at the age of thirty-four. He had been working for many years on a book about reference, but did not complete it before his death. The work was edited for publication by John McDowell, who contributes a Preface.
