Three different types of low cost soil amendments, namely, EDTA, elemental S and N-fertilizer, were investigated with Vetiver grass, Vetiveria zizanioides (Linn.) Nash growing under highly mixed Cd–Pb contamination conditions. A significant increase (p < 0.05) in Cd and Pb accumulation were recorded in the shoots of all EDTA and N-fertilizer assisted treatments. The accumulation of Cd in 25 mmol EDTA/kg soil and 300 mmol N/kg soil showed relatively higher translocation factor (1.72 and 2.15) and percentage (...) metal efficacy (63.25 % and 68.22 %), respectively, compared to other treatments. However, it was observed that the increased application of elemental S may inhibit the availability of Pb translocation from soil-to-root and root-to-shoot. The study suggests that viable application of 25 mmol EDTA/kg, 300 mmol N/kg and 20 mmol S/kg soil have the potential to be used for soil amendment with Vetiver grass growing under contaminated mixed Cd–Pb soil conditions.

This study used a flame atomic absorption spectrometer (FAAS) and atomic fluorescence spec-trophotometer (AFS) to detect the concentrations of chromium (Cr), cadmium (Cd), lead (Pb), hy-drargyrum (Hg) and arsenic (As) in soils and three genotypes of vegetables in greenhouse, as well as analyzed the physical and chemical properties of soils, including soil pH, soil organic matter (OM), basic nutrients, electrical conductivity (EC) and cation exchange capacity (CEC) in Guan- zhong areas, Shaanxi province, China. The results showed that comparing (...) to subsoil, the sampled topsoil is enriched in Cr, Cd, Pb, As and Hg. Cd (0.83 - 3.17 mg·kg-1) and Hg (0.40 - 1.44 mg·kg-1) are exceeding the limited value stated in “the 2006 Greenhouse Vegetable Producing Environmental Quality Evaluation Standards” of 0.40 mg·kg-1 and 0.35 mg·kg-1 respectively. However, Nanzhuang greenhouse soil is within the limits. The heavy metal pollution index (HPI) of soil in Sanyuan (8.10) is the highest and in Dongzhang (4.23) is the lowest. The contents of Pb (0.201 - 0.376 mg·kg-1) were exceeding the limited value (0.20 mg·kg-1) in vegetables species, and Cd (0.0363 - 0.0572 mg·kg-1) in some place were also exceeding the limited value (0.05 mg·kg-1). Greenhouse soils were becoming acidified year after year; the ratios of N, P and K in soil were seriously imbalanced. According to the impacting factors, OM, pH, available P, EC and CEC have obviously effected the accumulation of Cr and Hg. However, there was not enough evidence for the effects of available nitrogen and available potassium. (shrink)

Over the years, ethylene-diamine-tetra-acetate (EDTA) has been widely used for many purposes. However, there are inadequate phytoassessment studies conducted using EDTA in Vetiver grass. Hence, this study evaluates the phytoassessment (growth performance, accumulation trends, and proficiency of metal uptake) of Vetiver grass, Vetiveria zizanioides (Linn.) Nash in both single and mixed heavy metal (Cd, Pb, Cu, and Zn)—disodium EDTA-enhanced contaminated soil. The plant growth, metal accumulation, and overall efficiency of metal uptake by different plant parts (lower root, upper root, (...) lower tiller, and upper tiller) were thoroughly examined. The relative growth performance, metal tolerance, and phytoassessment of heavy metal in roots and tillers of Vetiver grass were examined. Metals in plants were measured using the flame atomic absorption spectrometry (F-AAS) after acid digestion. The root-tiller (R/T) ratio, biological concentration factor (BCF), biological accumulation coefficient (BAC), tolerance index (TI), translocation factor (TF), and metal uptake efficacy were used to estimate the potential of metal accumulation and translocation in Vetiver grass. All accumulation of heavy metals were significantly higher (p < 0.05) in both lower and upper roots and tillers of Vetiver grass for Cd + Pb + Cu + Zn + EDTA treatments as compared with the control. The single Zn + EDTA treatment accumulated the highest overall total amount of Zn (8068 ± 407 mg/kg) while the highest accumulation for Cu (1977 ± 293 mg/kg) and Pb (1096 ± 75 mg/kg) were recorded in the mixed Cd + Pb + Cu + Zn + EDTA treatment, respectively. Generally, the overall heavy metal accumulation trends of Vetiver grass were in the order of Zn >>> Cu > Pb >> Cd for all treatments. Furthermore, both upper roots and tillers of Vetiver grass recorded high tendency of accumulation for appreciably greater amounts of all heavy metals, regardless of single and/or mixed metal treatments. Thus, Vetiver grass can be recommended as a potential phytoextractor for all types of heavy metals, whereby its tillers will act as the sink for heavy metal accumulation in the presence of EDTA for all treatments.

Sources of soil contamination can exist in various types of conditions including in the form of semifluids. In this study, 3 different types of tropical plants, Acacia (Acacia mangium Willd), Mucuna (Mucuna bracteata DC. ex Kurz) and Vetiver (Vetiveria zizanioides L. Nash), were tested under different levels of soil-leachate conditions. The relative growth rate, metal tolerance, and phytoassessment of cadmium (Cd) and lead (Pb) accumulation in the roots and shoots were determined using flame atomic absorption spectrometry. Tolerance (...) index, translocation factor, metal accumulation ratio, and percentage metal efficacy were applied to assess the metal translocation ability among all the 3 types of plants. Significantly higher (P < .05) accumulation of Cd and Pb was exhibited in the roots and shoots of all 3 plants growing under the soil-leachate conditions. However, negative growth performance and plant withering were observed in both Acacia and Mucuna with increased application of higher soil-leachate levels. Vetiver accumulated remarkably higher total concentration of Cd (116.16-141.51 mg/kg) and Pb (156.37-365.27 mg/kg) compared with both Acacia and Mucuna. The overall accumulation trend of Cd and Pb in the 3 plants growing under the soil-leachate conditions was in the order of Vetiver > Acacia > Mucuna. The findings of the study suggest that Vetiver has great potential as Cd and Pb phytoremediator in soil-leachate conditions. (shrink)

The impact of crude oil on the permeability of the soil in a non oil producing community in Enugu State was investigated using disturbed A 6 CL soil sample collected from Ibagwa Nike area of the state. The sample was divided into five 5 portions and each of the four 4 portions was dosed with Bonny light crude oil at 2 , 4 , 6 and 8 by weight of the samples. The physical properties of the uncontaminated (...) class='Hi'>soil were tested and analyses and used as control. The aim of the laboratory investigation was to determine the effects of crude oil on the permeability of the soil. The permeability of the uncontaminated soil was found to be 1.2609x10 7. Permeability tests were also conducted on the contaminated soil samples at the various percentage contaminations. The results showed that at 2 crude oil contamination the permeability was 9.6403x10 9, a drastic reduction. The other results were 6.9600x10 6, 2.2621x10 8 and 9.1286x10 8 at 4 , 6 , and 8 contamination levels, respectively. The ranking after contamination is seen to drop within the range of 10 8 and 10 9 showing a change in the permeability due to oil content. This observed reduction in permeability alters the natural groundwater recharge which can be remedied by enhanced bioremediation through aeration of the soil. Iloeje A. F. | Aniago V.

Various types of plant species have been extensively used for heavy metals phyto-remediation without taking into consideration its tolerance threshold. In this study, Vetiver grass, Vetiveria zizanioides (Linn.) Nash was evaluated under five different sets of contaminated spiked cadmium (5Cd, 10Cd, 50Cd, 100Cd and 150Cd mg/kg) and lead (50Pb, 100Pb, 200Pb, 400Pb and 800Pb mg/kg) concentration levels in soil. The growth performance, metal tolerance and phyto-assessment of Cd and Pb in the roots and tillers were assessed using flame atomic (...) absorption spectrometry (FAAS). Tolerance index (TI), translocation factor (TF), biological transfer factor (BTF), biological accumulation coefficient (BAC) and metal uptake efficacy were used to determine the Cd and Pb translocation capability in Vetiver grass. Significantly higher (p<0.05) accumulation of Cd and Pb was recorded in the roots of all spiked treatments. Furthermore, strong and significantly positive correlations were exhibited between the increased levels of spiked heavy metal concentrations with both Cd (r=0.975) and Pb (r=0.952) accumulations. The results of this study showed Vetiver grass as an effective phyto-stabilizer for both Cd and Pb. Nevertheless, the growth of Vetiver grass was restricted when the tolerance threshold of 100 mg/kg (dry weight basis) Cd was exceeded in the contaminated soil. (shrink)

The growth response, metal tolerance and phytoaccumulation properties of water spinach (Ipomoea aquatica) and okra (Abelmoschus esculentus) were assessed under different contaminated spiked metals: control, 50 mg Pb/kg soil, 50 mg Zn/kg soil and 50 mg Cu/kg soil. The availability of Pb, Zn and Cu metals in both soil and plants were detected using flame atomic absorption spectrometry. The concentration and accumulation of heavy metals from soil to roots and shoots (edible parts) were evaluated in (...) terms of translocation factor, accumulation factor and tolerance index. Okra recorded the highest accumulation of Pb (80.20 mg/kg) in its root followed by Zn in roots (35.70 mg/kg) and shoots (34.80 mg/kg) of water spinach, respectively. Different accumulation trends were observed with, Pb > Zn > Cu in okra and Zn > Pb > Cu in water spinach. Significant differences (p < 0.01) of Pb, Zn and Cu accumulation were found in both water spinach and okra cultivated among tested treatments. However, only the accumulation of Pb metal in the shoots of water spinach and okra exceeded the maximum permissible levels of the national Malaysian Food Act 1983 and Food Regulations 1985 ([2006]) as well as the international Codex Alimentarius Commission limits. This study has shown that both water spinach and okra have good potential as Pb and Zn phytoremediators. (shrink)

Due to intensive agriculture, rapid industrialization and anthropogenic activities have caused environmental pollution, land degradation and increased pressure on the natural resources and contributing to their adulteration. Bioremediation is the use of biological organisms to destroy, or reduce the hazardous wastes on a contaminated site. Bioremediation is the most potent management tool to control the environmental pollution and recover contaminated soil. Use of biological materials, coupled to other advanced processes is one of the most promising and inexpensive approaches for (...) removing environmental pollutants. Bioremediation technology is a beneficial alternative which leads to degrade of pollutants. This article presents the important biological organisms used in bioremediation technologies. (shrink)

All the biotic and abiotic factors that act on an organism, population, or ecological community and influence its survival and development constitute its environment. Biotic factors include the organisms themselves, their food, and their interactions. Abiotic factors include such items as sunlight, soil, air, water, climate, and pollution. Organisms respond to changes in their environment by evolutionary adaptations in form and behaviour. At present humanity is facing great challenges for its survival as both these factors have come under great (...) stress due to its unbridled demands of national economic growth and individual needs and desires. Grave Crisis: On the abiotic front, a grave ecological crisis is caused by man’s exploitation of Nature, which is leading to a large scale depletion of natural resources, destruction of forests, and overuse of land for agriculture and habitation. Pollution is contaminating air, land, and water. Smoke from industries, homes and vehicles, is in the air. A smoky haze envelopes the major cities of the world. Industrial waste and consumer trash are choking streams and rivers, ponds and lakes, killing the marine life. Much of the waste is a product of modern technology. It is neither biodegradable nor reusable, and its longterm consequences are unknown. The viability of many animal and plant species, and possibly that of the humankind itself, is at stake. At the biotic level, humanity is facing a social justice crisis, which is caused by humanity’s confrontation with itself. The social justice crisis is that poverty, hunger, disease, exploitation and injustice are widespread. There are economic wars over resources and markets. The rights of the poor and the marginal are violated. Women, constituting half the world’s population, have their rights abused. Obviously, the contemporary human society is in the midst of a grave environmental crisis. There is a serious concern that the earth may no longer be a sustainable biosystem. Although human beings are seen as the most intelligent life form on earth, yet they are responsible for almost all the ecological damage done to the planet. The Sikh scripture, Sri Guru Granth Sahib (SGGS), declares that the purpose of human beings is to achieve a blissful state and to be in harmony with the earth and all of God’s creation. It seems, however, that humans have drifted away from that ideal. According to the Sikh scriptures, humans create their surroundings as a reflection of their inner state. Thus, the increasing barrenness of the earth reflects a spiritual emptiness within humans. (shrink)

Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But the notion of easy possibility in play is relatively undertheorized. One structural idea in the literature, the principle of Counterfactual Closure (CC), connects easy possibility with counterfactuals: if it easily could have happened that p, and if p were the case, then q would be the case, it follows that it easily could have happened that q. We first argue that while CC (...) is false, there is a true restriction of it to cases involving counterfactual dependence on a coin flip. The failure of CC falsifies a model where the easy possibilities are counterfactually similar to actuality. Next, we show that extant normality models, where the easy possibilities are the sufficiently normal ones, are incompatible with the restricted CC thesis involving coin flips. Next, we develop a new kind of normality theory that can accommodate the restricted version of CC. This new theory introduces a principle of Counterfactual Contamination, which says roughly that any world is fairly abnormal if at that world very abnormal events counterfactually depend on a coin flip. Finally, we explain why coin flips and other related events have a special status. A central take home lesson is that the correct principle in the vicinity of Safety is importantly normality-theoretic rather than (as it is usually conceived) similarity-theoretic. (shrink)

ABSTRACT The proper relationship between phenomenology and naturalism has reemerged as a pressing issue following interdisciplinary developments in the cognitive sciences. Most solutions opt for a naturalized phenomenology, rather than a phenomenological naturalism. This article takes up the latter approach, confronting the implications of Merleau-Ponty's reformulation of Husserl's paradox of subjectivity. I argue that Merleau-Ponty's formulation—which I term “the paradox of madness”—reveals a deep, ontological contingency in what Husserl took to be necessary transcendental structures of consciousness and world, revealing that (...) these transcendental structures are in fact embedded in and contaminated by the very world they constitute and disclose.

Many of the most important questions about primitive certainty have to do with the distinction between primitive certainty as a practical attitude or disposition and primitive certainty as a psychological attitude and with the distinction between these and primitive, objective certainty.

The way we farm, the kinds of backyards and landscapes we favor, and the way we control patterns of development are creating an invisible crisis through their affects upon soil ecology. The invisibility of soil ecosystems, the seemingly alien properties of the organisms that inhabit them, and the specialized knowledge required to understand them create obstacles to moral concern for these fountains of life. Our treatment of soils has reached the point of crisis. Obstacles to moral thinking about (...) soils might be overcome by supplying the moral imagination with a deeper understanding of our own biological identity as ecosystems analogous in organization and functions to soil ecosystems. Not only have microbes created the conditions necessary for human life, but they have shaped our evolutionary history and helped constitute the human genome. Our biological identity encompasses communities of microbes, such that humans (and all organisms) are most properly understood as ecosystems. For this reason, moral concern for humans implies moral concern for ecosystems. (shrink)

As populations grow and arable land becomes increasingly scarce, large-scale long- term land leases are signed at a growing rate. Countries and investors with large amounts of financial resources and a strong agricultural industry seek long-term land leases for agricultural exploitation or investment purposes. Leaders of financially poorer countries often advertise such deals as a fast way to attract foreign capital. Much has been said about the short-term social costs these types of leases involve, however, less has been said about (...) the normative dimension of their long-term environmental impact. We therefore will focus on the likely impact such deals have for soil conservation, by (1) briefly introducing the basics of long-term leasing arrangements by comparing land leases to the renting of buildings, (2) explaining from a soil sciences perspective the difficulties in assessing the current value of an estate and in calculating the damages of soil erosion and degradation, and (3) show how difficult it is to incentivize the conservation of soil quality when one cannot sufficiently and cost-effectively valorize existing environmental capital and eventual future damages. Attempting to oblige tenants through contracts to invest in sustainable stewardship has limited potential when liability payments do not reflect true costs and are hard to enforce. (shrink)

Many twentieth-century accounts of history have used geological tropes to describe the phenomenon of historical knowledge, and such terms have been of particular importance in the phenomenological tradition. In Heidegger's references in Being and Time to the "soil of history," Husserl's account in his later work of "sedimentation" in the lifeworld, and the reformulation of this notion in the phenomenology of Merleau-Ponty, geological tropes are used to illustrate important insights into the relation between contingency, a priority and historicity. This (...) paper seeks to contribute to an understanding of history understood phenomenologically as historicity through an analysis of these geological tropes. I argue that such geological tropes help the phenomenologist to describe the way in which history is always determined within a complex interplay between only temporarily fixed determining structures - such as riverbanks, insoluble sediment, soil, etc. - and free-flowing praxis, a situation in which historical events are at once determinant of and themselves determined by human activity. Paradoxically, the constant and "grounding" element in such conceptions of history is not the sediment and hard rock of historical fact, but the the constant change and variability-despite the sense giving continuity - of human experience structured by historicity. I begin with a brief overview of the landscape on the philosophy of history in which these views arose, and then continue to an analysis of the tropes themselves. (shrink)

Tropical grasses are fast growing and often used for phytoremediation. Three different types of tropical grasses: Vetiver (V. zizanoides), Imperata (I. cylindrical) and Pennisetum (P. purpureum) tested in different growth media of spiked heavy metal contents under the glasshouse environment of RimbaIlmu for 60-day. The growth performance, metals tolerance and phyto-assessment of cadmium (Cd), lead (Pb), zinc (Zn) and copper (Cu) in shoots and roots were assessed using flame atomic absorption spectrometry (FAAS).Tolerance index (TI), translocation factor (TF), biological accumulation coefficient (...) (BAC), biological concentration factor (BCF), and uptake efficacy was applied to evaluate the metal translocation ability among all three grasses. All three grasses showed significantly higher (p<0.05) accumulation of the total heavy metals in the spiked metal treatment compared with other tested treatments. Vetiver accumulated remarkably higher total concentration of Cd (93.08 ± 3.81 mg/kg) and Zn (1284.00 ± 234.83 mg/kg) than both Imperata and Pennisetum. The overall trend of heavy metals accumulation for all three grasses followed the order of Zn>Pb>Cd>Cu. The results of study suggested that both Imperata and Pennisetum are commendable and potential phytoextractors for Zn as well as phytostabilizers for Cd, Pb and Cu, respectively. (shrink)

A wide family of many-valued logics—for instance, those based on the weak Kleene algebra—includes a non-classical truth-value that is ‘contaminating’ in the sense that whenever the value is assigned to a formula φ⁠, any complex formula in which φ appears is assigned that value as well. In such systems, the contaminating value enjoys a wide range of interpretations, suggesting scenarios in which more than one of these interpretations are called for. This calls for an evaluation of systems with multiple contaminating (...) values. In this paper, we consider the countably infinite family of multiple-conclusion consequence relations in which classical logic is enriched with one or more contaminating values whose behavior is determined by a linear ordering between them. We consider some motivations and applications for such systems and provide general characterizations for all consequence relations in this family. Finally, we provide sequent calculi for a pair of four-valued logics including two linearly ordered contaminating values before defining two-sided sequent calculi corresponding to each of the infinite family of many-valued logics studied in this paper.

This article interrogates a certain philosophical scene – one which constitutes itself through the position of what Jacques Derrida calls “the ethical instance of violence.” This scene supposes a certain “style” of writing or doing philosophy, and perhaps even a certain philosophical “genre” or “subgenre”: the philosophical discourse on violence. In the course of the essay, I analyze this quasi-juridical scene through readings of Aristotle, Walter Benjamin, Giorgio Agamben, Judith Butler, Slavoj Žižek, Werner Hamacher, Rodolphe Gasché, and Martin Hägglund among (...) others. The scene, built on texts on texts on violence, demands a logic of purity; it is wary of contaminations and equivocations. And yet it thrives on them. In analyzing the implications of text, writing, and trace for the philosophical discourse on violence, I follow Derrida “just to see” what could make the scene tremble. (shrink)

Logics based on weak Kleene algebra (WKA) and related structures have been recently proposed as a tool for reasoning about flaws in computer programs. The key element of this proposal is the presence, in WKA and related structures, of a non-classical truth-value that is “contaminating” in the sense that whenever the value is assigned to a formula ϕ, any complex formula in which ϕ appears is assigned that value as well. Under such interpretations, the contaminating states represent occurrences of a (...) flaw. However, since different programs and machines can interact with (or be nested into) one another, we need to account for different kind of errors, and this calls for an evaluation of systems with multiple contaminating values. In this paper, we make steps toward these evaluation systems by considering two logics, HYB1 and HYB2, whose semantic interpretations account for two contaminating values beside classical values 0 and 1. In particular, we provide two main formal contributions. First, we give a characterization of their relations of (multiple-conclusion) logical consequence—that is, necessary and sufficient conditions for a set Δ of formulas to logically follow from a set Γ of formulas in HYB1 or HYB2 . Second, we provide sound and complete sequent calculi for the two logics. (shrink)

Abstract: Global chemical contamination is an underexplored source of global catastrophic risks that is estimated to have low a priori probability. However, events such as pollinating insects’ population decline and lowering of the human male sperm count hint at some toxic exposure accumulation and thus could be a global catastrophic risk event if not prevented by future medical advances. We identified several potentially dangerous sources of the global chemical contamination, which may happen now or could happen in the (...) future: autocatalytic reactions, exposure to multiple subthreshold sources, and long-term unintended consequences, arising from both natural and bioengineered sources. We list several especially dangerous chemicals—dioxin, organiс compounds, and toxic heavy metals. We also discuss the features of such dangerous chemicals—molecules that can stay in the biosphere for a long time and affect it over time. We explore several social processes and scenarios where global chemical contamination becomes possible: large natural catastrophe like meteorite impact, supervolcano eruption, new ways of predicting properties of the chemicals via machine learning and their manufacturing via synthetic biology, uncontrolled “capitalistic” economic development with a corresponding large waste production, quick adoption of many chemicals with unknown long-term properties and unintended side-effects. These are all low probability, so work on other global catastrophic risks should be prioritized, but chemical risks could exacerbate other types of catastrophe contributing to social collapse.

Phytoremediation is a biological remediation technique known for low-cost technology and environmentally friendly approach, which employs plants to extract, stabilise, and transform various compounds, such as potentially toxic elements (PTEs), in the soil or water. Recent developments in utilising chelating agents soil remediation have led to a renewed interest in chelate-induced phytoremediation. This review article summarises the roles of various chelating agents and the mechanisms of chelate-induced phytoremediation. This paper also discusses the recent findings on the impacts of (...) chelating agents on PTEs uptake and plant growth and development in phytoremediation. It was found that the chelating agents have increased the rate of metal absorption and translocation up to 45% from roots to the aboveground plant parts during PTEs phytoremediation. Besides, it was also explored that the plants may experience some phytotoxicity after adding chelating agents to the soil. However, due to the leaching potential of synthetic chelating agents, the use of organic chelants have been explored to be used in PTEs phytoremediation. Finally, this paper also presents comprehensive insights on the significance of using chelating agents through SWOT analysis to discuss the advantages and limitations of chelate-induced phytoremediation.

Abstract: Northern state, Sudan is extremely affected by desertification and Salinization processes, there for this study aimed to investigate an effective method to improve the salt affected soil. Two field experiments were carried out in two successive seasons ( July 2005 – June 2006 ) at Dongola University farm, in the North State to investigate the effect of irrigation frequency ( 7 and 14 days ) and farm yard manure (M0 , M1 , M2 , andM3 ) on salt (...) leaching undersaline – sodic soil . The experiment was designed in spilt – plot design , where irrigation frequency was assigned in the main plots ( 6x28m) and farm yard manure were the sub – plots ( 6x7m) .The total cultivated area was 1342m2 for each experiment. The quantity of water applied was estimated according to Jensen andHaise (1963 ) . The total water quantity was the same by the end of the season. In general , the result indicated that irrigation frequency of 7 days enhanced salt leaching from the root zone. Generally , the reduction in electrical conductivity ( ECe ) and sodium adsorption ratio ( SAR ) due to irrigation frequency was more effective in 7 day irrigation interval as compared with 14 – day irrigation interval . the data obtained indicated that the addition of FYM 10 ton/feddan, significantly degreased the (ECe) and the (SAR) and leached them below the root zone. So, we can conclude that the efficiency of salt leaching is markedly affected by irrigation frequency and yard manure. (shrink)

In this article, an account of the architecture of the cognitive contamination system is offered, according to which the contamination system can generate contamination represen- tations in circumstances that do not satisfy the norms of contamination, including in cases of mere visual contact with disgusting objects.

The foundation of a building connects the main body superstructure to the ground. Every form of foundation and footing have a unique application in a given location for a certain weather condition. Understanding the foundation work is crucial for carrying out building activities. Due to the variety of structures they support, foundations are frequently built in different subsoil conditions and are exposed to static loads. The proper evaluation of soil-bearing capacity is fundamental to the construction of various buildings. One (...) of the quick, easy, and affordable ways to determine soil carrying capacity is the plate load test. The effect of subsoil conditions on the test results is assessed and analyzed in thorough parametric investigations. An overview of axial static and dynamic plate load testing will be given in this study. This article presents detailed processes and schematics. In an effort to highlight the differences and shared characteristics of the results, computational test results of the static load plate test and the dynamic load plate test are contrasted. A load cell, a steel plate, a hydraulic actuator mounted on a big truck to apply a load, a load cell to measure the load, and one or more linear variable displacement transformers to measure the vertical displacements make up the test setup. The maximum thrust load that should be applied to a fixed or stationary actuator when it is not moving is known as a "static load depending on the actuator's static load capacity, we can determine what a safe load is. The maximum thrust load that should be applied to the actuator while it is moving is known as a dynamic load. Dynamic load capacity refers to how much force an actuator can exert when driven and extending or retracting. With each method's benefits and drawbacks considered, it can be determined that using them in various situations and agreeing to the confrontation of these tests for the purpose of comparing results is the best course of action in order to have a base that satisfies the construction standards.

Starting from the importance of the figure of the parrhesiastes — the political and therapeutic truth- teller— for Foucault’s understanding of the care of the self, this paper traces the political figuration of the analogy between philosophers and physicians on the one hand, and rhetors and disease on the other in Plato’s Gorgias. I show how rhetoric, in the form of ventriloquism, infects the text itself, and then ask how we account for the effect of the “ contaminated ” philosophical (...) dialogue on our readerly health. Is the text placebo, vaccine, or virus? All of these options, I argue, complicate Foucault’s prescription for parrhesia, requiring us to think anew the continuing political ramifications of the metaphor of care. (shrink)

We use Bayesian tools to assess Law’s skeptical argument against the historicity of Jesus. We clarify and endorse his sub-argument for the conclusion that there is good reason to be skeptical about the miracle claims of the New Testament. However, we dispute Law’s contamination principle that he claims entails that we should be skeptical about the existence of Jesus. There are problems with Law’s defense of his principle, and we show, more importantly, that it is not supported by Bayesian (...) considerations. Finally, we show that Law’s principle is false in the specific case of Jesus and thereby show, contrary to the main conclusion of Law’s argument, that biblical historians are entitled to remain confident that Jesus existed.

The accumulation of potentially toxic elements (PTEs) has raised public awareness due to harmful contamination to both human and marine creatures. This study was designed to determine the concentration of copper (Cu), zinc (Zn), cadmium (Cd), and nickel (Ni) in the intestine, kidney, muscle, gill, and liver tissues of local commercial edible fish, fourfinger threadfin (Eleutheronema tetradactylum), and black pomfret (Parastromateus niger) collected from Morib (M) and Kuala Selangor (KS). Among the studied PTEs, Cu and Zn were essential elements (...) to regulate body metabolism with certain dosages required while Cd and Ni were considered as non-essential elements that posed chronic and carcinogenic risk. The concentration of PTEs in fish tissue samples was analyzed using flame atomic absorption spectrometry (F-AAS). By comparing the concentration of PTEs in fish tissues as a bioindicator, the environmental risk of Morib was more serious than Kuala Selangor because both fish species collected from Morib resulted in a higher PTEs concentration. For an average 62 kg adult with a fish ingestion rate (FIR) of 0.16 kg/person/day in Malaysia, the estimated weekly intake (EWI) of Cd from the consumption of E. tetradactylum (M: 0.0135 mg/kg; KS: 0.0134 mg/kg) and P. niger (M: 0.0140 mg/kg; KS: 0.0132 mg/kg) had exceeded the provisional tolerable weekly intake (Cd: 0.007 mg/kg) established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and oral reference dose (ORD) values of Cd (0.001 mg/kg/day) as provided by the United States Environmental Protection Agency (USEPA) regional screening level, thus it posed chronic risks for daily basis consumption. Besides, the value of the carcinogenic risk of Cd (0.7−3 to 0.8−3) and Ni (0.5−3 to 0.6−3) were in between the acceptable range (10−6 to 10−4) of the health index that indicates a relatively low possibility cancer occurrence to the consumers in both Morib and Kuala Selangor. This study recommended FIR to be 0.80 kg/person/day to reduce the possibility of posing chronic and carcinogenic risks while at the same time obtaining the essential nutrients from the fish.

This chapter articulates two concerns that Karl Jaspers raised (with Hannah Arendt) about the common practice of viewing moral evil as unintelligible. The first is that this involves exoticizing the act and/or perpetrator in such a way that moral condemnation becomes difficult. The second is that it can lead us to treat the perpetrator, place, or victim as tainted or stained by a force whose motives we cannot grasp; this in turn can lead to magical thinking about evil as somehow (...) contagious or contaminating. After distinguishing some of the main categories of evil discussed in the western tradition, I examine ways in which moral evil, in particular, has been characterized as unintelligible, and try to discern which of them raises these Jaspersian concerns. I argue that there are at least two conceptions of “radical evil”—not the Kantian one, but the ones articulated by Hannah Arendt—that do so. (shrink)

Kant scholars have paid relatively little attention to his raciology. They assume that his racism, as personal prejudice, can be disentangled from his core philosophy. They also assume that racism contradicts his moral theory. In this book, philosopher Huaping Lu-Adler challenges both assumptions. She shows how Kant's raciology--divided into racialism and racism--is integral to his philosophical system. She also rejects the individualistic approach to Kant and racism. Instead, she uses the notion of racism as ideological formation to demonstrate how Kant, (...) from his social location both as a prominent scholar and as a lifelong educator, participated in the formation of modern racist ideology. As a scholar, Kant developed a ground-breaking scientific theory of race from the standpoint of a philosophical investigator of nature or Naturforscher. As an educator, he transmitted denigrating depictions of the racialized others and imbued those descriptions with normative relevance. In both roles, he left behind, as one of his legacies, a worldview that excluded non-whites from such goods as recognitional respect and candidacy for cultural and moral achievements. Scholars who research and teach Kant's philosophy therefore have an unshakable burden to take part in the ongoing antiracist struggles, through their teaching practices as well as their scholarship. And they must do so with a pragmatic attention to nonideal social realities and a deliberate orientation toward substantial racial justice, equality, and inclusion. Lu-Adler pushes the discourse about Kant and racism well beyond the old debates about whether he was racist or whether his racism contaminates his philosophy. By foregrounding the lasting legacies of Kant's raciology, her work calls for a profound reorientation of Kant scholarship. (shrink)

Moral error theory of the kind defended by J. L. Mackie and Richard Joyce is premised on two claims: (1) that moral judgements essentially presuppose that moral value has absolute authority, and (2) that this presupposition is false, because nothing has absolute authority. This paper accepts (2) but rejects (1). It is argued first that (1) is not the best explanation of the evidence from moral practice, and second that even if it were, the error theory would still be mistaken, (...) because the assumption does not contaminate the meaning or truth-conditions of moral claims. These are determined by the essential application conditions for moral concepts, which are relational rather than absolute. An analogy is drawn between moral judgements and motion judgements.

The diversity in agronomic practices being used by sugarcane producers in Brazil determines differences in economic performance and cost structure. The purpose of this study is to evaluate the cost of six systems of agronomic practices using fixed or variable rates for soil amendment, fertilizer, and defensive applications and assess the profitability of these systems at three scales of sugarcane production. We then describe the data sample related to the 2019–2020 harvest season and collected from fifty-five sugarcane producers in (...) the central-south region of Brazil. Thereafter, using a quantitative approach, a cost analysis was performed, and the cumulative frequency of the net revenue for the three scales of production (small, medium, and large), was calculated using a Monte Carlo simulation. The cost analysis indicated that fertilizer had the highest cost considering the agronomic practices adopted at the three scales of production analyzed. The cumulative frequency analysis results from the Monte Carlo simulation showed the highest net revenue per hectare for medium sugarcane producers. In addition, the presence of economies of scale was not confirmed because the lowest cost was found in small-scale sugarcane producers and the highest net revenue was obtained by medium-scale sugarcane producers.

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and (...) ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).

Environmental health research produces scientific knowledge about environmental hazards crucial for public health and environmental justice movements that seek to prevent or reduce exposure to these hazards. The environment in environmental health research is conceptualized as the range of possible social, biological, chemical, and/or physical hazards or risks to human health, some of which merit study due to factors such as their probability and severity, the feasibility of their remediation, and injustice in their distribution. This paper explores the ethics of (...) identifying the relevant environment for environmental health research, as judgments involved in defining an environmental hazard or risk, judgments of that hazard or risk's probability, severity, and/ or injustice, as well as the feasibility of its remediation, all ought to appeal to non-epistemic as well as epistemic values. I illustrate by discussing the case of environmental lead, a housing-related hazard that remains unjustly distributed by race and class and is particularly dangerous to children. Examining a controversy in environmental health research ethics where researchers tested multiple levels of lead abatement in lead-contaminated households, I argue that the broader perspective on the ethics of environmental health research provided in the first part of this paper may have helped prevent this controversy.

Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

The teikei movement is a Japanese version of the alternative food movement, which emerged around the late 1960s and early 1970s. Similar to now well-known Community Supported Agriculture, it is a farmer-consumer partnership that involves direct exchanges of organic foods. It also aims to build a community that coexists with the natural environment through mutually supportive relationships between farmers and consumers. This article examined the history of the teikei movement. The movement began as a reaction to negative impacts of mechanized (...) and chemically intensive agriculture promoted by the Japanese government. The movement experienced a rapid expansion in the early 1980s, and then gradually declined thereafter. The organic market expansion and certification system intersected with both cultural and gender role changes, impacting the teikei movement negatively. Consequently, the membership of teikei consumer groups has shrunk. Furthermore, the March 2011 Fukushima Daiichi nuclear power plant accident caused unprece dented damage to organic farmers in the affected regions. Despite the scientific uncertain about the safety level of radiation exposure, the organic farmers and the teikei consumer groups managed the situation and found a way to inspect radiation contamination. They did so with the support by networking with other teikei-related actors. This response to the nuclear power plant accident suggests that although the level of embeddedness presumably varies among teikei actors, ethics guided by the teikei principles are effective in forging a resilient partnership between farmers and consumers and in keeping the teikei system alive as an agent for social change.

This paper develops a “Cliffordian” argument for a common epistemic norm governing belief, action, and assertion. The idea is that beliefs are the sorts of things that lead to actions and assertions. What each of us believes influences what we act on and assert, and in turn influences what those around us believe, act on, and assert. Belief, action, and assertion should be held to a common epistemic norm because, otherwise, this system will become contaminated. The paper finishes by drawing (...) out the relativistic implications of the Cliffordian argument. (shrink)

I offer a new argument for the elimination of ‘beliefs’ from cognitive science based on Wimsatt’s concept of robustness and a related concept of fragility. Theoretical entities are robust if multiple independent means of measurement produce invariant results in detecting them. Theoretical entities are fragile when multiple independent means of detecting them produce highly variant results. I argue that sufficiently fragile theoretical entities do not exist. Recent studies in psychology show radical variance between what self-report and non-verbal behaviour indicate about (...) participants’ beliefs. This is evidence that ‘belief’ is fragile, and is thus a strong candidate for elimination. 1 Introduction2 Robustness and Fragility2.1 A historical example of robustness2.2 Fragility and elimination3 The Received View4 Evidence for the Fragility of Belief4.1 Contamination and fragility4.2 Implicit association tests and fragility5 Attempts to Preserve the Belief Category for Cognitive Science5.1 Beliefs and aliefs5.2 Contradictory beliefs5.3 In-between beliefs and the unity assumption5.4 Belief sub-classes5.5 Self-deception6 Alternative Mental States7 Conclusion.

Badiou claims Deleuze’s thinking is pre-critical metaphysics that cannot be understood in relation to Kant. I argue that Deleuze is indeed a metaphysical thinker, but precisely because he is a kind of Kantian. Badiou is right that Deleuze rejects the overwhelmingly epistemic problematics of critical thought in its classical sense, but he is wrong to claim that Deleuze completely rejects Kant. Instead, Deleuze is interested in developing a metaphysics that prolongs Kant’s conception of a productive synthesis irreducible to empirical causation. (...) Where Badiou’s criticism might tell however is in the risk that Deleuze’s strategy runs of contaminating his new metaphysics with a new kind of transcendental idealism. This reading has recently been developed by Ray Brassier and I explore and evaluate it, concluding that in Difference and Repetition this accusation may be correct, but that by the time of Anti-Œdipus, Deleuze (now with Guattari) has the intellectual resources to resist it.

The article offers an attempt to understand the present state of Kant’s legacy in Russia on the threshold of the Tercentenary. An explanans is found in the metaphors of “ tabula rasa ” and “unplowed virgin soil,” first used by Leibniz in relation to Russia in his letters and memoranda addressed to tsar Peter I and other members of the Russian elite, which became the country’s “absolute metaphors to live by” up to present time. Several known and unknown episodes (...) from the history of the reception of Kantian ideas, his followers in Russia, and the transformation of the urban environment of Kant’s life in Königsberg, as it was becoming Kaliningrad, are presented through the prism of this metaphor. Without hoping to make specific recommendations of any use from such metaphorical grounds, this study aims to emphasize the depth, interconnectedness, and basic, metaphysical tension of the relationship between Europe and Russia, which cannot be terminated at will by either side, or by a third party. In a situation where the sides are doomed to dialog, Kant, appropriated by Russia as its “subject,” occupies the unique position of mediator of philosophical understanding and peaceful action.

In lieu of an abstract, here is a brief excerpt of the content:This Universalism Which Is Not OneLinda M. G. Zerilli (bio)Ernesto Laclau. Emancipation(s). London: Verso, 1996.Judging from the recent spate of publications devoted to the question of the universal, it appears that, in the view of some critics, we are witnessing a reevaluation of its dismantling in twentieth-century thought. One of the many oddities about this “return of the universal” 1 is the idea that contemporary engagements with it are (...) more or less of a piece, and that they reflect a growing consensus that poststructuralist political theories are incapable of generating a viable alternative to the collective fragmentation that characterizes late modernity. 2 The putative return to the universal marks, on this view, both a homecoming to Enlightenment ideals—purified of their more poisonous elements, of course—and a reconciliation of sorts between those who refuted these ideals and those who sought to realize them. Now that “we” all know and agree that poststructuralism is critically valuable but politically bankrupt; now that we all know and agree that the “old universal” was indeed a “pseudo-universal,” so the homecoming narrative goes; we can get on with the project of constructing a “new universal.” 3 This authentic universal would really be inclusive of all people, regardless of race, class, gender, sexuality, ethnicity, nationality, and whatever else attaches to the “embarrassing etcetera” that, as Judith [End Page 3] Butler reminds us, inevitably accompanies such gestures of acknowledging human diversity.Before signing on to this felicitous agreement about “the necessity of universalism,” we may wish to know whether we have anything like a minimal agreement in language, that is, whether we who speak of this universal are even speaking about the same thing. Apart from the not insignificant problem of translating from a philosophical to a political idiom, the whole question of this agreement is virtually occluded by the rush to rescue politics from the virulent particularisms that admit no common ground or sense of collective belonging. Presented in terms of the familiar binary couple, the choice between universalism and particularism seems settled by merely pointing to global and domestic political realities. Universalism is the only alternative to social fragmentation, wild child of the collapse of communism, the rise of deadly nationalisms, and the multiculturalist romance with particularism. To invoke the name of the universal in any affirmative sense is already to sign on to the political diagnosis and its solution.One of the many virtues of Ernesto Laclau’s Emancipation(s) is that it offers both an alternative to the binarisms spawned by the “return” to the universal (for example, false universalism/true universalism) and a trenchant critique of the original binary couple itself (universalism/ particularism). Demonstrating the imbrication of the universal and the particular, Laclau shows why it is a matter not of choosing one over the other but of articulating, in a scrupulously political sense, the relation between the two. He thus explicitly rejects the notion that this relation is one of mutual exclusion, and shows that the tendency to see it as just that has led to the impasse of the contemporary debate, an impasse that is glossed over in some highly visible academic cases by proclaiming the necessary return to the universal. Although the language of universalism as spoken by Laclau searches for some common ground between particularists and universalists, it is more by way of articulating their mutual contamination, that is, how each is rendered impure by the irreducible presence of the other.The Problem of UniversalsLaclau situates his collection of essays in the context of the increasingly polarized debate over multiculturalism, a debate in which the classical universalism of the philosophical tradition has come under serious question. Reading his essays, one comes to see the deep dependence of the entire contemporary discussion on this tradition, even when its metaphysical assumptions are explicitly rejected (as, say, in the work of Seyla Benhabib) or insufficiently comprehended (as in most of the popularized political discourse). Laclau’s book can help us to see that the political question of universalism cannot be posed properly as long as it remains tethered to the classical philosophical “problem of universals.” At stake in sorting out the affinities and...

Air pollutants pose a threat to biodiversity throughout the world. This study was conducted to evaluate atmospheric element accumulation in Isparta city, including Gölcük Nature Park, located in the Western Mediterranean Region of Turkey. It is aimed to determine the air quality and potential pollutant sources in the region through lichen biomonitoring. Specimens of the epiphytic foliose lichen Physcia aipolia (Erh. ex Humb.) Fürnr. were sampled from 14 sites in the study area and analyzed by ICP-MS with reference material in (...) order to detect 11 trace elements; Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn. The spatial distribution of these airborne elements in the study area was mapped. The results showed that the elemental sequence in terms of average concentrations measured was as follows: Ni >Cr >V >Fe >As >Al >Zn >Cu> >Cd >Mn >Pb. The results of cluster analyses of the elemental data indicated that the 3 major contaminants in the urban area were Cr, Ni, and V, probably due to the extensive use of coal in heating facilities and gasoline in vehicles. P. aipolia specimens accumulated maximal concentrations of As, Cr, Fe, Ni, and V in the northern and the southeastern localities surrounding the city, while Cd, Pb were most abundant in the eastern edge of Gölcük Nature Park. The pollution in Isparta city with heavy metal is worse than expected, mostly due to the extensive use of coal as fossil fuel. In addition, it seems to be associated with the city's topographic and climatic characteristics, e.g. inversion effects. (shrink)

Music can infect us. In the dominant approach, music contaminates listeners through emotional mimicry and independently of value appraisal, just like when we catch other people’s feelings. Musical contagion is thus considered fatal to the mainstream view of emotions as cognitive evaluations. This paper criticizes this line of argument and proposes a new cognitivist account: the value metaphor view. Non-cognitivism relies on a contentious model of emotion transmission. In the competing model (social appraisal), we catch people’s emotions by appraising value (...) through their emotional expressions. Social appraisal debunks the main motivation for non-cognitivism and offers fruitful insights into musical contagion. Combining it with metaphor theory, I claim that musical contagion involves experiencing the music as a metaphor for emotions and values. Just like people infect us as we appraise value through their emotional expressions, music contaminates listeners because they hear it metaphorically-as some emotional expression and hereby appraise it metaphorically-as some value. As infectious music “sounds like” emotions and values, cognitivism is safe. (shrink)

The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

Michael Marder in Dump Philosophy claims that that there has been so much dumping with modern civilization that we now live in a dump, with those parts of our environment not contaminated by dumping, now rare. The growth of the dump is portrayed as the triumph of nihilism, predicted by Nietzsche as the outcome of life denying Neoplatonist metaphysics. Marder’s proposed solution, characterized as “undumping”, is to accept the dump and to promote reinterpretations and informal communities within the dump. It (...) is argued here that Marder provides great insight into our current situation and its causes; however, his proposed solution is too weak. To respond to the situation described, it is argued, it is necessary to distinguish between healthy and unhealthy dumping, or more broadly, healthy and unhealthy participation in nature. To make this distinction, it is necessary see humans as ecosystems and components of ecosystems, including the global ecosystem, as these have been characterized by anti-reductionist ecologists. Ecosystems can be healthy or unhealthy. Dumping and dumps should be identified as problematic outputs when they damage the health of ecosystems. The products of human activity not destined to be consumed or used for further productive activity, can then be identified and judged according to whether they augment or damage ecosystems’ health. Dumping should be severely restricted. This should be associated with making a commitment to life and its value, and living to augment life, developing the social and economic forms and institutions that facilitate living in this way.

In his The Meaning of Disgust, Colin McGinn employs elements of the phenomenological theory of disgust advanced by Aurel Kolnai in 1929. Kolnai’s treatment of what he calls “material” disgust and of its primary elicitors—putrefying organic matter, bodily wastes and secretions, sticky contaminants, vermin—anticipates more recent scientific treatments of this emotion as a mode of protective recoil. While Nina Strohminger charges McGinn with neglecting such scientific studies, we here attempt to show how Kolnai goes beyond experimental findings in his careful (...) description of the phenomenological differences between disgust and other emotions of forceful disapproval.

Given that one-million species are currently threatened with extinction and that humans are undermining the entire natural infrastructure on which our modern world depends (IPBES, 2019), this dissertation will show that there is a need to provide an alternative approach to wildlife conservation, one that avoids anthropocentrism and wildlife valuation on an instrumental basis to provide meaningful and tangible success for both wildlife conservation and human well-being in an inclusive way. In this sense, The Value of Being Wild will showcase (...) the concept of eco-phenomenology as an important non-anthropocentric alternative to the current approach to wildlife conservation, namely sustainable development. The problem with this dominant paradigm, as Chapter Two will reveal, is that sustainable development has not only failed to provide humans and future generations of humans with their own needs but, as per the latest IPBES report, failed in arresting the freefall decline of wild species. The situation currently requires a radical overhaul of the current system. As emerged from the later work of French phenomenologist, Maurice Merleau-Ponty (1908-1961), eco-phenomenology is particularly well-suited as a practical alternative to sustainable development. The core reason is that eco-phenomenology moves away from a human-centred framework toward a far more inclusive approach that embraces the conservation of wild animals as well the wild environment they dwell in, beyond any human needs (although humans are embraced within the approach too). Merleau-Ponty helps us to move away from anthropocentrism to a more inclusive approach in conserving wildlife, since his phenomenology does not consider the human animal’s relationship in the world as exclusive (to use and exploit wild animals solely for their benefit), but inclusive (as an interconnected biological component in a broad ecological system). The strength of Merleau-Ponty’s concept of phenomenology is that it facilitates an understanding of all living and even non-living entities, such as air, water and soil, as interconnected and interrelated within a broad biosphere. While Merleau-Ponty did not address the concept of wild animals or the biosphere directly, his later work points to the fact that human animals cannot exist outside a world that provides life-giving force to all living beings. Phenomenology, as developed by Merleau-Ponty, is a concept that recognises the axiological qualities of the natural world are inherent and ineliminable from the discipline of traditional phenomenology, hence the term ‘eco-phenomenology’, developed in one reception of his thinking. Eco-phenomenology offers a return to a world that humans have tried hard to alienate themselves from, in that it approaches the natural environment and wild animals, not as a complex set of objects and objective processes, but rather as they are experienced and lived from within by the attentive animal who is entirely a part of the world that he or she experiences. Merleau-Pontian eco-phenomenology thus emphasises a holistic dialogue within a more-than-human world (Abram, 1996: 65). Eco-phenomenology is a concept that points toward an applied strategy but so far this has not been attempted in earnest. This is specifically true when it comes to wildlife conservation. The Value of Being Wild, therefore, sets out to employ the concept of eco-phenomenology in order to provide a new practical wildlife conservation approach that challenges, and potentially replaces, the current prevailing policies as employed by global governmental and inter-governmental agencies. In particular, this alternative frame is posed as a replacement for the failing anthropocentric conservation practices currently in place in South Africa. This dissertation will therefore conclude by exploring strategies where conservation of wildlife is not taken as instrumentally-valued, or even intrinsically-valued, but rather as wild-valued in that the existence of wild animals as wild is conserved within a broader, more inclusive overall ecology that supports the survival and flourishing of all living beings that include plants, wild animals and human beings.
