Morality has always been a pressing issue in video game scholarship, but became more contentious after “realistic” violence in games became possible. However, few studies concern themselves with how players experience moral dilemmas in games, choosing instead to focus on the way games affect postplay behavior. In my thesis I discuss the moral choices players encounter in the Metal Gear series of games; then, I analyze and compare the responses of players with and without martial career experiences. My (...) argument is that the moral choices players encounter during gameplay affect them differently, particularly if they have life experiences related to medical trauma, law enforcement, fire fighting, or military career fields, and that the behavior of those players will be observably different from players without the same experiences. In chapter one I present my personal history with Metal Gear, before moving on to the literature review in chapter two, which focuses on scholarship about the Metal Gear series of games and video game research as a whole, particularly studies concerned with how violent content affects players. In chapters three and four, I analyze Metal Gear Solid 3 (2004) and Metal Gear Solid V (2014/2015) in order to gain insight into the moral dilemmas posed by each game. In chapter five I report the results of a survey about player responses towards the game dilemmas given by martial and non-martial groups to identify observable patterns of behavior in how they act and react towards each scenario. -/- This is a preprint version of the official paper until an update is produced.

This paper focuses on the question of filtration through the perspective of “too much information”. It concerns Western society within the context of new media and digital culture. The main aim of this paper is to apply a philosophical reading on the video game concept of Selection for Societal Sanity within the problematics of cultural filtration, control of behaviors and desire, and a problematization of trans-individuation that the selected narrative conveys. The idea of Selection for Societal Sanity, which derives from (...) the first postmodern video game Metal Gear Solid 2: Sons of Liberty (2001), is applied into a philosophical framework based on select concepts from Bernard Stiegler’s writing and incorporating them with current events such as post-truth or fake news in order to explore the role of techne and filtration within social organizations and individual psyches. Alternate forms of behavior, which contest cultural paradigms, are re-problematized as tension between calculability and incalculability, or market value versus social bonding. (shrink)

Die Frage nach der Ethik in Computerspielen fragt im Kern danach, wie Computerspiele moralische Fragen aushandeln können. Ausgangspunkt ist die folgende Beobachtung: Situationen und Tätigkeiten, die in Wirklichkeit¹ moralisch brisant wären, sind seit jeher ein beliebter Gegenstand von Computerspielen. Seien es spielerische Umsetzungen von Kriegssituationen wie in den Reihen Call of Duty oder Metal Gear Solid, seien es heftige körperliche Auseinandersetzungen wie in Tekken oder auch in Super Smash Bros., seien es bleihaltige Abenteuer wie in Uncharted oder Tomb (...)

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)

It has recently been argued that metal’s ‘heaviness’ is conceptually inarticulable. I argue, on the contrary, that ‘heaviness’ is a matter of inaccessibility—the ‘something more’ that makes metal ‘heavy’ is actually something less: less auditory processing fluency. Like profound literature, metal resists, but also invites and rewards, interpretation. I argue that understanding ‘heaviness’ in terms of auditory processing fluency allows us to make sense of a number of otherwise puzzling features of the music, and to articulate a (...) unifying gestalt for the genre.

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)

Here, I explore a modernist aesthetics of death metal. First, I briefly describe a few themes that characterize some modern art, without any claim that they are necessary, sufficient, or exhaustive. The goal is to obtain a set of themes that might be set against similar themes characteristic of death metal. This is the task in the second half of the paper. In particular, I argue that (some) modernist art and death metal share themes centered on transgressively (...) breaking with the past, pursue their conception of the truth, eliminate elements in their art form to purity them, and attack the art/non-art or music/non-music distinction. I contend that centering on death metal vocals reflects these themes. Death metal growls, like some modernist art, transgresses on past vocal traditions, tells us important truths, eliminates traditional concepts/techniques of signing, and undermines the singing/noise distinction.

Abstract The rapid growth of Indonesian Heavy Metal music, especially the Death Metal subgenre, since around the turn of the millennium, has been quite remarkable. Indonesia is now numerically the largest scene in the world. Man, the vocalist of Jasad, told the author that the provincial West Javanese city of Bandung had 128 active Death Metal bands as at February 2011. This chapter will discuss the cancellation of an April 2012 music festival held in the Bandung hinterland (...) by police halfway through the festival, and explain how and why it took place. Police became nervous and worried about Heavy Metal shows following the deaths of eleven concertgoers, due to a crowd crush, at a Beside album launch in Bandung in 2008. The chapter analyses the “maternal rage” of a band member’s mother (also a policewoman at the scene) from the perspective of grounded gendered cosmopolitanism. Lastly, a short case study of Sickles, a young band from the religiously-conservative Madura Island, shows the problems that young bands experience plus the type of global underground support which they can attract.

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)

E-waste, also known as waste from electrical and electronic equipment, is a solid waste that accumulates quickly due to high demand driven by the market for replacing newer electrical and electronic products. The global e-waste generation is estimated to be between 53.6 million tons, and it is increasing by 3–5% per year. Metals make-up approximately 30% of e-waste, which contains precious elements Au, Ag, Cu, Pt, and other high-value elements, valued at USD 57 billion, which is driving the e-waste recycling (...) industry. It is noteworthy that the recycling of precious elements from e-waste has emerged as a profitable enterprise in several parts of developing nations. E-waste contains 50–100 times higher levels of precious metals compared to natural ores, making it suitable for mining. E-waste recycling in developing nations, mostly occurs through the informal sector comprising manual collection, crushing, segregation and selling of precious elements, such as Au, Ag, Cu, Pb, Pt, and other rare elements (Nd, In, and Ga). The organized sector, on the other hand, mostly employs mechano-chemical methods, such as pyrometallurgy, hydrometallurgy, and bio-hydrometallurgy, which have serious environmental consequences. Both the informal and formal sectors of e-waste processing lead to the leaching of toxic elements into groundwater and soils. Owing to the lesser efficiency of greener technologies, such as phytoremediation and bioremediation, their use in precious metal extraction is very limited. However, this review explores several hyper-accumulating and tolerant plants viz. Brassica juncea and Berkheya coddii, which holds great potential in phytomining of precious metal from e-waste. Thus, the state of the art in precious metal extraction from e-waste as well as the advantages and disadvantages of different metal extraction technologies has been reviewed. (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.

Wittgenstein’s comment that what can be shown cannot be said has a special resonance with visual representations of power in both Heavy Metal and Fundamentalist Christian communities. Performances at metal shows, and performances of ‘religious theatre’, share an emphasis on violence and destruction. For example, groups like GWAR and Cannibal Corpse feature violent scenes in stage shows and album covers, scenes that depict gory results of unrestrained sexuality that are strikingly like Halloween ‘Hell House’ show presented by neo-Conservative, (...) Fundamentalist Christian churches in the southeastern United States’ ‘Bible Belt’. One group may claim to celebrate violence, the other sees violence as a tool to both encourage ‘moral’ behaviour, and to show that the Christian church is able to ‘speak the language’ of young people who are fans of metal, gore, and horror. Explicit violence, in each case, signifies power relationships that are in transformation. Historically, medieval morality plays and morality cycles had been used as a pedagogical tool. In the modern-day context of fundamentalist religious education, these Hell House performances seek to exclude outsiders and solidify teen membership in the Christian community. Hell House performances are marketed to the young church members, and are seen as a way to reinvigorate conservative Fundamentalist Christianity. Women and girls routinely take part in, and often organize Hell House events. In the context of heavy metal, violent performances do not seek to exclude, but provide an outlet for a variety of socially unacceptable or unpopular feelings. In each context there is an apparent, if not actual, empowering of women who are willing to play particular kinds of roles. The use of violence and gore has a value beyond merely shocking the audience, it is arguably a way that some women find their voice, both for fundamentalist Christians and fundamentalist gore metal fans.

This paper introduces a novel conceptualisation of mental imagery; namely, that is grease for the mind’s gears (MGT). MGT is not just a metaphor. Rather, it describes an important and overlooked higher-order function of mental imagery: that it aids various mental faculties discharge their characteristic functional roles. MGT is motivated by reflection on converging evidence from clinical, experimental and social psychology and solves at least two neglected conceptual puzzles about mental imagery. The first puzzle concerns imagery’s architectural promiscuity; that is, (...) its ability to assist diverse mental faculties and perform many different functions when doing so. The second puzzle concerns how to square imagery’s architectural promiscuity with its psychopathological relevance; that is, its being a maintaining cause, and possibly even a partial constituent, of several psychological disorders, including post-traumatic stress disorder, bipolar disorder and major depressive disorder. Mental imagery helps and harms human psychology to extreme degrees and this is something that calls for elucidation. MGT says that instead of facing perplexing heterogeneities here, we instead face a significant unity. On this score, MGT is argued to be superior to the currently dominant conception of imagery in the philosophical literature; namely, as a perception-like state of mind. (shrink)

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 paper explores how a set of observations on the weight of lead were interpreted and assessed between the 1540s and the 1630s across three different interconnecting disciplines: medicine, mineralogy and chemistry. The epistemic import of these discussions will be demonstrated by showing: 1) the changing role and articulation of experience and quantification in the investigation of metals; and 2) the notions associated with weight in different disciplinary frameworks. In medicine and mineralogy, weight was not considered as a specific subject (...) of inquiry in itself, but as a “sign” indicating other relevant properties of metals. In contrast, the chemistry tradition was increasingly concerned with the specific investigation of weight as a property of matter, as seen in the debates that took place in the “chemical revolution.” In addition, this study will reveal the versatility, polysemy, and parallel purposes of the recourse to experiential knowledge in different contexts, where the same “facts” operate within different disciplines.

The Ganga is one of the most sacred and worshipped river of India, is regarded as the cradle of Indian civilization. Uttar Pradesh the largest state of India is blessed with the most holy and important river in its region but due to increased urbanization and industrialization this river is under intimidation of high water pollution. The major objectives of the present study were to investigate heavy metal's concentration in water and sediments of the River Ganga. Water and sediments (...) collected from different locations were analyzed for Iron (Fe), Chromium (Cr), Lead (Pb),Nickel(Ni) and Zinc(Zn). The concentration of these heavy metals in the study area indicates that the river is highly polluted. The possible sources of these heavy metal pollutants are diverse, originated from natural or anthropogenic sources and point sources. The concentrations determined were more than the maximum admissible and desirable limit when compared with the National and International organizations like WHO, USEPA. Exposure to heavy metals has been linked to chronic and acute toxicity developing retardation, neurotoxicity, kidney damage, various cancers, liver damage, lung damage, and fragile bones and even death in instances of very high exposure.

People have said for generations that money is based on "trust," or "shared fiction." But that doesn't explain why cultures all eventually come to value the same metals or items as money. Others have said that the value of money depends on the way it facilitates trade, but even that doesn't explain where the value emerges before people agree to use money to trade. In actuality, there's a real value to gold, silver, and other forms of money that makes them (...) reliably gain worth to people, and will emerge eventually even if everyone in a society does not like or believe in those precious metals or possessions. This is because possessing scarce objects has real reputational value among people, since having those objects indicates that we can go outside the known territory, and we instinctively collect and want things that have known scarcity. When that scarcity combines with other traits like transferability, durability and so on, we can see that money naturally emerges in society. We can use this idea to also see the real value and desire that people have for new forms of money like cryptocurrencies, and to know what will or won't emerge and last as a form of money in the future.

This paper adopts two modeling tools, namely, multiple linear regression (MLR) and artificial neural networks (ANNs), to predict the concentrations of heavy metals (zinc, boron, and manganese) in surface waters of the Oued Inaouen watershed flowing towards Inaouen, using a set of physical-chemical parameters. XLStat was employed to perform multiple linear and nonlinear regressions, and Statista 10 was chosen to construct neural networks for modeling and prediction. The effectiveness of the ANN- and MLR-based stochastic models was assessed by the determination (...) coefficient (R²), the sum squared error (SSE) and a review of fit graphs. The results demonstrate the value of ANNs for prediction modeling. Drawing on supervised learning and back propagation, the ANN-based prediction models adopt an architecture of [18-15-1] for zinc, [18-11-1] for manganese, and [18-8-1] for boron, and perform effectively with a single cached layer. It was found that the MLR-based prediction models are substantially less accurate than those based on the ANNs. In addition, the physical-chemical parameters being investigated are nonlinearly correlated with the levels of heavy metals in the surface waters of the Oued Inaouen watershed flowing towards Inaouen.

The main aim of this paper is to clarify the relation between epistemic feel- ings, mental action, and self-ascription. Acting mentally and/or thinking about one’s mental states are two possible outcomes of epistemic or metacognitive feelings. Our men- tal actions are often guided by our E-feelings, such as when we check what we just saw based on a feeling of visual uncertainty; but thought about our own perceptual states and capacities can also be triggered by the same E-feelings. The first (...) section of the pa- per presents Dokic’s argument for the insufficiency of the “ascent routine” to account for non-transparent cases of self-ascription, as well as his account of E-feelings. The second section then presents a two-level model of metacognition that builds on Dokic’s account and my own view of the issue. The two-level model links E-feelings to a min- dreading capacity in order to account for non-transparent self-ascriptions. Finally, the third section develops a deeper characterization of the relation among E-feelings, mental action, and self-ascription of mental states based on epistemic rules. In the context of self-knowledge, these remarks suggest the existence of means of forming self-ascriptions other than the ascent routine. (shrink)

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)

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)

This article was motivated by the avalanche of finance spent annually on addressing the harm caused by corrosion on household wares and buildings, industrial machines and facilities, hospital equipment and many other establishment of man in the universe. Corrosion is a universal phenomenon referred to as the deterioration of metallic material. Metal alloys like stainless steel and aluminium are extensively used in household utensils for their durability, affordability and corrosion resistance. However, these materials can leach heavy metals such as (...) chromium, nickel, iron, and aluminium into food, posing serious health challenges. Stainless steel, despite its corrosion resistance, releases harmful metals when exposed to acidic foods, while aluminium utensils corrode and release harmful elements under certain conditions too. Hence, this article was aimed at examining the historical background of corrosion, the causes of corrosion in household wares and utensils, its impact especially on human health and economy, and the potential remedies. The findings indicated that acidic foods and prolonged storage increase metal leaching. Health concerns included increased risks of anemia, dementia, and osteomalacia due to excessive metal accumulation in the body. Mitigation strategies included using anodized aluminium, minimizing storage time of acidic foods in metal containers, and increasing public awareness about the potential health risks. Proper maintenance and selection of utensils could significantly reduce the hazards associated with metal leaching. (shrink)

We ask whether it is reasonable to delay or refuse to take COVID-19 vaccines that have been shown in clinical trials to be safe and effective against infectious diseases. We consider two kinds of vaccine hesitancy. The first is geared to scientifically informed open questions about vaccines. We argue that in cases where the data is not representative of relevant groups, such as pregnant women and ethnic minorities, hesitancy can be reasonable on epistemic grounds. However, we argue that hesitancy is (...) not reasonable if a vaccine has passed well-conducted clinical trials. The second kind of hesitancy is to do with beliefs about the institutions offering a successfully trialled vaccine and the justifiability of cooperating with those institutions. For example, in the UK, distrust of the UK Government or the National Health Service is identified as a factor in the vaccine hesitancy of minority ethnic populations. We ask whether this sort of hesitation is reasonable given normative requirements of fair co-operation, both with those institutions and the wider population. We suggest that the answer is not straightforward. Sometimes the hesitation is unreasonable but understandable. -/- . (shrink)

Martin and Deutscher’s remarkable 1966 paper ‘Remembering’ still offers great riches to memory researchers across distinctive traditions, both in its methodological ambition (successfully marrying phenomenological and causal discourses) and in its content. In this short discussion, after briefly setting the paper in its context, we hone in on two live and under-explored issues which have gained attention recently under new labels – the extended mind hypothesis, and the constructive nature of memory. We suggest that Martin and Deutscher’s causal analysis of (...) memory is compatible with the idea that activities of remembering may be distributed across heterogeneous social and external resources, focussing in on their neglected example of creatures who ‘remember as we do’ as long as they carry round metal boxes which are given to them at birth. We then argue that the causal analysis is in some tension with the extent to which remembering is a constructive activity, because there may be no clear way to determine the appropriate ‘limits of accuracy’ within which a past event or experience must be represented.

A great many important decisions we make in life depend on scientific information that we are not in a position to assess. So it seems we must defer to experts. By now there are a variety of criteria on offer by which non-experts can judge the trustworthiness of a scientist responsible for producing or promulgating this information. But science is, for the most part, a collective not an individual enterprise. This paper explores which of the criteria for judging the trustworthiness (...) of individual scientists can be amended for use in assessing the trustworthiness of scientific collectives. It also offers some new proposals specifically geared to assessing collective trustworthiness in science, notably, an analysis of where to apply the criteria (for example at the group or individual level) and additional criteria to assess group infrastructure and design. The paper ends with some practical suggestions for how to assist the non-expert in this task. (shrink)

1. Animal Cruelty Industrial farming is appallingly abusive to animals. Pigs. In America, nine-tenths of pregnant sows live in “gestation crates. ” These pens are so small that the animals can barely move. When the sows are first crated, they may flail around, in an attempt to get out. But soon they give up. Crated pigs often show signs of depression: they engage meaningless, repetitive behavior, like chewing the air or biting the bars of the stall. The sows live like (...) this for four months. Gestation crates will be phased out in Europe by the end of 2012, but they will still be used in America.1 In nature, pigs nurse their young for about thirteen weeks. But in industrial farms, piglets are taken from their mothers after about ten days. Because the piglets are weaned prematurely, they develop a lifelong craving to suck and chew. But the farmers don’t want them sucking and chewing on other pigs’ tails. So the growers routinely snip off the tails of all their pigs. They do this with a pair of pliers and no anesthetic. However, the whole tail is not removed; a tender stump remains. The point is to render the area sensitive, so the pigs being chewed on will fight back. Which they do.2 Over 113 million pigs are slaughtered each year in America.3 Typically, these pigs are castrated, their needle teeth are clipped, and one of their ears is notched for identification —all without pain relief.4 In nature, pigs spend up to three quarters of their waking hours foraging and exploring their environment.5 But in the factory farms, “tens of thousands of hogs spend their entire lives ignorant of earth or straw or sunshine, crowded together beneath a metal roof standing on metal slats suspended over a septic tank. ”6 Bored, and in constant pain, the pigs must perpetually inhale the fumes of their own waste. These pigs often get sick, and their ill health is exacerbated by the overcrowding. In 2000, the U.S. Department of Agriculture compared hog farms containing over 10,000 pigs—which is the norm—with farms containing under 2,000 pigs. (shrink)

La exterioridad de una cosa o de un estado de cosas configurados por el ser humano no implica para Hegel que esa cosa o ese estado de cosas deban ya por ello ser considerados como formas del espíritu objetivo, mientras que en contrapartida las formas del espíritu absoluto estarían entonces conformadas por contenidos ideales del pensamiento. La diferencia entre espíritu objetivo y espíritu absoluto no radica en la diferencia entre lo que el espíritu humano “hace” y lo que “conoce”. En (...) efecto, las obras de arte, es decir, configuraciones exteriores hechas por el ser humano utilizando, por ejemplo, piedras, metales, colores o sonidos, son para Hegel instancias del espíritu absoluto, mientras que, por su parte, realidades que en cuanto tales no son intuibles, como, por ejemplo, los contratos o la organización estatal, son instancias del espíritu objetivo. Que Hegel considere al arte como una forma del espíritu absoluto pone de manifiesto que, a sus ojos, las cosas que intuimos en el universo son, en rigor, productos del propio sujeto que las conoce. Espontáneamente el sujeto cognoscente piensa que lo que intuye es algo que recibe desde un mundo externo; sostener que el arte es una forma de conocimiento es justamente el modo como Hegel está expresando que lo intuido es en todos los casos un contenido producido por el propio espíritu, que es, por así decirlo, una obra de arte humano. En el arte mismo, sin embargo, la producción de la cosa intuible es insuficiente, dado que el material que el espíritu utiliza para sus configuraciones conserva en mayor o menor medida, según el caso, una determinidad propia que resiste a la determinidad que el espíritu busca conferirle. Por esta razón, las obras de arte se presentan inicialmente como productos arbitrarios. Recién cuando integra sus intuiciones en la actividad de comprensión -actividad cognitiva con la que opera la filosofía- y media con ello completamente la determinidad de los contenidos intuidos, el espíritu configura finalmente un universo que le es propio y específico. El objetivo de mi ponencia es reconstruir desde el marco teórico recién expuesto el sentido y función que Hegel le atribuye al arte en su teoría del conocimiento. (shrink)

Today, a major challenge for climate science is to overcome what is called the “usability gap” between the projections derived from climate models and the needs of the end-users. Regional Climate Models (RCMs) are expected to provide usable information concerning a variety of impacts and for a wide range of end-users. It is often assumed that the development of more accurate, more complex RCMs with higher spatial resolution should bring process understanding and better local projections, thus overcoming the usability gap. (...) In this paper, I rather assume that the credibility of climate information should be pursued together with two other criteria of usability, which are salience and legitimacy. Based on the Swiss climate change scenarios, I study the attempts at meeting the needs of end-users and outline the trade-off modellers and users have to face with respect to the cascade of uncertainty. A conclusion of this paper is that the trade-off between salience and credibility sets the conditions under which RCMs can be deemed adequate for the purposes of addressing the needs of end-users and gearing the communication of the projections toward direct use and action.

Iris Murdoch claims that “clear vision is a result of moral imagination and moral effort.” Our experience of the world can be blurred by egoism, inattentiveness, and other failings. I ask how we distinguish clear vision from distorted vision. Murdoch’s texts appeal to four factors: (A) attention; (B) unselfing; (C) a form of conceptual articulacy; and (D) love. I ask three questions about these standards: - Are these standards directed at the same goal? (For example, are they all geared toward (...) securing purely epistemic goals?) - Are these standards criterial for improvements in vision? (That is, does the presence of some combination of (A)-(D) constitute or guarantee better vision?) - Does Murdoch think that there’s a single best form of vision? (Such as the one attained by the person who manifests (A)-(D)?) In the secondary literature, the typical answers to these questions are: yes, yes, yes. But I give different answers: no, no, no.

Popper's well-known demarcation criterion has often been understood to distinguish statements of empirical science according to their logical form. Implicit in this interpretation of Popper's philosophy is the belief that when the universe of discourse of the empirical scientist is infinite, empirical universal sentences are falsifiable but not verifiable, whereas the converse holds for existential sentences. A remarkable elaboration of this belief is to be found in Watkins's early work on the statements he calls “all-and-some,” such as: “For every (...) class='Hi'>metal there is a melting point.” All-and-some statements are both universally and existentially quantified in that order. Watkins argued that AS should be regarded as both nonfalsifiable and nonverifiable, for they partake in the logical fate of both universal and existential statements. This claim is subject to the proviso that the bound variables are “uncircumscribed” ; i.e., that the universe of discourse is infinite. (shrink)

According to the standard and largely traditional interpretation, Aristotle’s conception of nous, at least as it occurs in the Posterior Analytics, is geared against a certain set of skeptical worries about the possibility of scientific knowledge, and ultimately of the knowledge of Aristotelian first principles. On this view, Aristotle introduces nous as an intuitive faculty that grasps the first principles once and for all as true in such a way that it does not leave any room for the skeptic to (...) press his skeptical point any further. Thus the tradi- tional interpretation views Aristotelian nous as having an internalist justificatory role in Aristotelian epistemology. In contrast, a minority (empiricist) view that has emerged recently holds the same internalist justificatory view of nous but rejects its internally certifiable infallibility by stressing the connection between nous and Aristotelian induction. I argue that both approaches are flawed in that Aristotle’s project in the Posterior Analytics is not to answer the skeptic on internalist justificatory grounds, but rather lay out a largely externalist explication of scientific knowledge, i.e. what scientific knowledge consists in, without worrying as to whether we can ever show the skeptic to his satisfaction that we do ever possess knowledge so defined.

We introduce the working concept of “affective arrangement.” This concept is the centerpiece of a perspective on situated affectivity that emphasizes relationality, dynamics, and performativity. Our proposal relates to work in cultural studies and continental philosophy in the Spinoza–Deleuze lineage, yet it is equally geared to the terms of recent work in the philosophy of emotion. Our aim is to devise a framework that can help flesh out how affectivity unfolds dynamically in a relational setting by which it is at (...) the same time modulated in recurring ways. With this orientation, this article contributes to the interdisciplinary study of situated affectivity and to the theoretical and conceptual unification of distinct strands of research from several disciplines.

This is a long critical discussion of Frank Wilderson's Afropessimism, focusing primarily on Wilderson's claim that Blackness is equivalent to Slaveness. The article draws out some strengths of the book, but argues that the book's central arguments often rest on shaky methodological, metaphysical, epistemic, and political grounds. Along the way, we consider some complications endemic to the project of evaluating a text so clearly geared towards Black audiences from the perspective of a non-Black reader.

Resolving religious disagreements is difficult, for beliefs about religion tend to come with strong biases against other views and the people who hold them. Evidence can help, but there is no agreed-upon policy for weighting it, and moreover bias affects the content of our evidence itself. Another complicating factor is that some biases are reliable and others unreliable. What we need is an evidence-weighting policy geared toward negotiating the effects of bias. I consider three evidence-weighting policies in the philosophy of (...) religion and advocate one of them as the best for promoting the resolution of religious disagreements. (shrink)

The market capitalization of an enterprise is one of the key indicators characterizing the degree of influence of financial and non-financial instruments on its volumes and dynamics. Establishing the relationship between such instruments and metrics of equity and cash flows best delineates the plane of their direct impact on stimulating market capitalization. This is aimed at ensuring the implementation of effective management measures in the context of optimizing the use of equity and cash flows. The aim of the study was (...) to establish how the influence of indicators of financial and non-financial instruments on equity and cash flows forms a relevant basis for making management decisions to increase enterprise market capitalization. During the research, the following methods were used: summarization and grouping, multiple linear regression, direct ranking method, establishment of cause-and-effect relationships, logical generalization, and analytical method. As a result of the study, the toolkit for increasing the market capitalization of the enterprise from the standpoint of its grouping in terms of financial and non-financial plane was clarified. It was found that among the 36 analyzed indicators of the impact on equity and cash flows of the studied machine-building enterprises in Ukraine during the period 2010-2021, the most significant are bank lending, investment and technical metals, research and development costs, foreign scientific and technical services received, production investments, work-in-progress, and accounts payable for products, goods, and services. The results were transformed into a model of ranked instruments for stimulating the market capitalization of machine-building enterprises, which demonstrates the degree and directions of the influence of indicators of financial and non-financial instruments on the dynamics of equity and cash flows, which ensures the formation of an information database for making decisions on the further use of such instruments. The structuring of the toolkit serves as the basis for forming a system of management decisions containing practical recommendations within each group of instruments aimed at optimizing market capitalization through increased equity and cash flows of the enterprise. The obtained results will be beneficial to financial analysts of enterprises in preparing databases for making financial and non-financial decisions. (shrink)

People sometimes use speech to interfere with other people’s speech, as in the case of a heckler sabotaging a lecture with constant interjections. Some people claim that such interference infringes upon free speech. Against this view, we argue that where competing speakers in a public forum both have an interest in speaking, free speech principles should not automatically give priority to the ‘official’ speaker. Given the ideals underlying free speech, heckling speech sometimes deserves priority. But what can we say, then, (...) about situations in which heckling clearly seems to infringe upon people’s civil liberties, in a way that intuitively justifies intervention? In such cases, we argue, heckling infringes upon people’s associative freedom. We present and defend an ethical framework for the institutional management of ‘Speech Fights’, geared around this insight. (shrink)

This chapter attends to somaesthetic expressions occurring irrespective of knowledge of the movement, using Mandalay’s Water Festival and Cairo’s Arab Spring as case studies. These celebrations and protests feature bodies creatively gravitating around urban structures and according to emotional, cultural concerns, all of this together defining city spaces for a time. Bodies also become venues for artistic refashioning, for example, through creative conversion of injuries into celebratory badges of dissent. Geared almost therapeutically towards life-improvement—albeit sometimes implicitly—these celebrations and protests also (...) have meliorative aspects that mark the somaesthetic movement. Moreover, they have a shared, public character stressed by Shusterman, but arguably lost on many because of his interest in self-focused meditation and the popular appeal of such exercises among those interested in body practices.

The cultural practice of flirtation has been multifariously scrutinized in various disciplines including sociology, psychology, psychoanalysis and literary studies. This paper frames the field of flirtation in Bourdieuian terms, while focusing narrowly on the semiotic economy that is defining of this cultural field. Moreover, seduction, as a uniquely varied form of discourse that is responsible for producing the cultural field of flirtation, is posited as the missing link for understanding why flirtation may be a peculiar case of non-habitus, contrary to (...) the received notion of cultural field as set of goaloriented practices and actionable habituses. This argument is pursued by highlighting the endemic traits of ambivalence and constant reversibility of signs or multimodal semiotic constellations in the discourse of seduction, while seeking to demonstrate that seduction, and by implication the cultural field of flirtation, does not necessarily partake of a teleological framework that is geared towards the consummation of sexual desire. This thesis is illustrated by recourse to a scene from the blockbuster ‘Hitch’. (shrink)

Building upon Nancy Cartwright's discussion of models in How the Laws of Physics Lie, this paper addresses solid state research in transition metal oxides. Historical analysis reveals that in this domain models function both as the culmination of phenomenology and the commencement of theoretical explanation. Those solid state chemists who concentrate on the description of phenomena pertinent to specific elements or compounds assess models according to different standards than those who seek explanation grounded in approximate applications of the Schroedinger (...) equation. Accurate accounts of scientific debate in this field must include both perspectives. (shrink)

The literature contains two concepts of corruption which are often confused with one another: corruption as twisted character (pollution), and corruption as disloyalty. It also contains two sites for corruption: the corruption of individuals, and the corruption of entire institutions such as a state or a legislature.This paper first draws a clear distinction between the pollution and disloyalty concepts of corruption in the individual context, and then defends a conception of disloyalty corruption according to which the distinguishing feature is an (...) agent who uses powers delegated to her from her principal as her own. Then, the paper shifts gears to the institutional context, arguing that the best account of institutional corruption in the extant literature is of the pollution kind. It then fills the remaining logical space by laying out a conception of institutional corruption as disloyalty and explaining its moral significance for the political legitimacy of a democracy.

The co-evolutionary concept of three-modal stable evolutionary strategy of Homo sapiens is developed. The concept based on the principle of evolutionary complementarity of anthropogenesis: value of evolutionary risk and evolutionary path of human evolution are defined by descriptive (evolutionary efficiency) and creative-teleological (evolutionary correctness) parameters simultaneously, that cannot be instrumental reduced to other ones. Resulting volume of both parameters define the vectors of biological, social, cultural and techno-rationalistic human evolution by two gear mechanism — genetic and cultural co-evolution and (...) techno-humanitarian balance. Explanatory model and methodology of evaluation of creatively teleological evolutionary risk component of NBIC technological complex is proposed. Integral part of the model is evolutionary semantics (time-varying semantic code, the compliance of the biological, socio-cultural and techno-rationalist adaptive modules of human stable evolutionary strategy).

Operational activity such crime prevention is extremely significant in promoting peace and order of the community. This study assessed the Pasay City Police Station in the Southern District regarding particular organization and crime operations management capabilities. This paper used quantitative research anchored by descriptive method. The study’s respondents were 130 police officers/members and 150 permanent employees of the Pasay City Police Station who are residents of Pasay City and whose offices are near the police station. It was revealed that the (...) organization variables describing the Pasay City Police Station is “not significant” leading to accept the null hypothesis. The problems encountered by the Pasay City Police Station are grounded from the standpoint of personnel needs, facilities, supplies and equipment, the suggestions offered by the respondent to help solve the problems encountered are specifically geared towards solving the particular problems encountered. The Pasay City Police Officers/Personnel will be more effective in solving crime problem if more intelligence officer is dispatch where criminality is rampant. It is recommended to improve police efficiency and effectiveness in crime prevention, reduction, solution, and crime management capability. There is also a need to increase the number of police officers for the Pasay City Police Station who are educationally qualified and highly trained on police matters. (shrink)

Although scientific realism is the default position in the life sciences, philosophical accounts of realism are geared towards physics and run into trouble when applied to fields such as biology or neuroscience. In this paper, I formulate a new robustness-based version of entity realism, and show that it provides a plausible account of realism for the life sciences that is also continuous with scientific practice. It is based on the idea that if there are several independent ways of measuring, detecting (...) or deriving something, then we are justified in believing that it is real. I also consider several possible objections to robustness-based entity realism, discuss its relationship to ontic structural realism, and show how it has the potential to provide a novel response to the pessimistic induction argument.
