The class Matr(C) of all matrices for a prepositional logic (, C) is investigated. The paper contains general results with no special reference to particular logics. The main theorem (Th. (5.1)) which gives the algebraic characterization of the class Matr(C) states the following. Assume C to be the consequence operation on a prepositional language induced by a class K of matrices. Let m be a regular cardinal not less than the cardinality of C. Then Matr (C) is the least class (...) of matrices containing K and closed under m-reduced products, submatrices, matrix homomorphisms, and matrix homomorphic counter-images. (shrink)

Answering a question of Cifú Lopes, we give a syntactic characterization of those continuous sentences that are preserved under reduced products of metric structures. In fact, we settle this question in the wider context of general structures as introduced by the second author.

Assume $\langle \aleph_0, \aleph_1 \rangle \rightarrow \langle \lambda, \lambda^+ \rangle$ . Assume M is a model of a first order theory T of cardinality at most λ+ in a language L(T) of cardinality $\leq \lambda$ . Let N be a model with the same language. Let Δ be a set of first order formulas in L(T) and let D be a regular filter on λ. Then M is $\Delta-embeddable$ into the reduced power $N^\lambda/D$ , provided that every $\Delta-existential$ formula (...) true in M is true also in N. We obtain the following corollary: for M as above and D a regular ultrafilter over $\lambda, M^\lambda/D$ is $\lambda^{++}-universal$ . Our second result is as follows: For $i < \mu$ let Mi and Ni be elementarily equivalent models of a language which has cardinality $\leq \lambda$ . Suppose D is a regular filter on λ and $\langle \aleph_0, \aleph_1 \rangle \rightarrow \langle \lambda, \lambda^+ \rangle$ holds. We show that then the second player has a winning strategy in the $Ehrenfeucht-Fra\ddot{i}ss\acute{e}$ game of length λ+ on $\prod_i M_i/D$ and $\prod_i N_i/D$ . This yields the following corollary: Assume GCH and λ regular (or just $\langle \aleph_0, \aleph_1 \rangle \rightarrow \langle \lambda, \lambda^+ \rangle$ and 2λ = λ+). For L, Mi and Ni be as above, if D is a regular filter on λ, then $\prod_i M_i/D \cong \prod_i N_i/D$. (shrink)

The authors show. by means of a finitary version $\square_{\lambda D}^{fin}$ of the combinatorial principle $\square_\lambda^{h*}$ of [7]. the consistency of the failure, relative to the consistency of supercompact cardinals, of the following: for all regular filters D on a cardinal A. if Mi and Ni are elementarily equivalent models of a language of size $\leq \lambda$ , then the second player has a winning strategy in the Ehrenfeucht- $Fra\uml{i}ss\acute{e}$ game of length $\lambda^{+}$ on $\pi_{i} M_{i}/D$ and $\pi_{i} N_{i}/D$ . (...) If in addition $2^{\lambda} = \labda^{+}$ and i < $\lambda$ implies | $M_{i}$ | +| $N_{i}$ | $\leq$ \lambda^{+} this means that the ultrapowers are isomorphic. This settles negatively conjecture 18 in [2]. (shrink)

This article discusses the ethics of knowledge production from a cultural point of view, in contrast with the more usual emphasis on the ethical issues facing individuals involved in KP. Here, the emphasis is on the cultural environment within which individuals, groups and institutions perform KP. A principal purpose is to suggest ways in which reliable scientific knowledge could be produced more efficiently. The distinction between ethical hazard and ethical behaviour is noted. Ethical hazards cannot be eliminated but they can (...) be reduced if the cultural ambience is suitable. The main suggestions for reducing ethical hazards in KP relate to the review process. It is argued that some defects of the current, largely anonymous, review process could be ameliorated by a process of comprehensive, open and ongoing review. This includes partial professionalisation of the work of reviewing. Review at several stages is a vital part of the long filtering that incorporates some claims into the canon of reliable knowledge. The review process would be an acknowledged and explicit part of KP—a respected, public and rewarded activity. COOR would be expensive but cost-effective. The costs should be built explicitly into research culture. Finally, the considerations about a more ‘KP friendly’ culture lead to advocacy of a ‘long-term, short-term’ synthesis; that is, of the synthesis of long-term vision, such as a more cooperative and less competitive culture, with incremental changes which may be implemented in the short term.

Does product market competition (PMC) promote or reduce firms’ corporate social responsibility (CSR) behavior? While some studies suggest that CSR is a differentiation strategy that leads to a positive relationship between PMC and CSR, others consider CSR a discretionary cost that firms in competitive markets should avoid. Drawing on instrumental stakeholder theory and research on organizational attention, we aim to clarify the extent to which CSR provides a competitive advantage for firms by exploring how different types of stakeholder attention—both (...) between different stakeholder groups and within a specific stakeholder group—affect the PMC–CSR relationship. We test our framework using data on Chinese private (i.e., non-state-owned) companies on major Chinese stock exchanges from 2008 to 2017. Overall, our analyses highlight that stakeholder attention affects how firms assess the tension between the benefits and costs of CSR and that the contingent effect of different stakeholder attention varies within and between stakeholder groups.

By analyzing how one obtains the Stone space of the reduced product of an indexed collection of Boolean algebras from the Stone spaces of those algebras, we derive a topological construction, the "reduced coproduct", which makes sense for indexed collections of arbitrary Tichonov spaces. When the filter in question is an ultrafilter, we show how the "ultracoproduct" can be obtained from the usual topological ultraproduct via a compactification process in the style of Wallman and Frink. We prove (...) theorems dealing with the topological structure of reduced coproducts (especially ultracoproducts) and show in addition how one may use this construction to gain information about the category of compact Hausdorff spaces.

The increasing prevalence of ecologically sustainable products in consumer markets, such as organic produce, are generally assumed to curtail anthropogenic impacts on the environment. Here I intend to present an alternative perspective on sustainable production by interpreting the relationship between recent rises in organic agriculture and greenhouse gas emissions from agricultural production. I construct two time series fixed-effects panel regressions to estimate how increases in organic farmland impact greenhouse gas emissions derived from agricultural production. My analysis finds that the rise (...) of certified organic production in the United States is not correlated with declines in greenhouse gas emissions derived specifically from agricultural production, and on the contrary is associated positively overall agricultural greenhouse gas emissions. To make sense of this finding, I embed my research within the conventionalization thesis. As a result I argue that the recent USDA certification of organic farming has generated a bifurcated organic market, where one form of organic farming works as a sustainable counterforce to conventional agriculture and the other works to increase the economic accessibility of organic farming through weakening practice standards most conducive to reducing agricultural greenhouse gas output. Additionally, I construct my own theoretical framework known as the displacement paradox to further interpret my findings. (shrink)

Increasing the willingness to reduce animal product consumption has the potential to contribute to ameliorating the impact of animal agriculture on the environment, as well as foster healthier diets and improve the lives of farmed and wild animals. Reduction of animal product consumption is a prosocial behaviour (PSB), and factors that are considered to influence it are empathy and selfishness. In this research, animal-oriented empathy examined empathy specifically for animals. Animal oriented empathy and three types of selfishness: adaptive, (...) egoistic, and pathological were measured to determine if they could predict willingness to reduce animal product consumption. PSB is also influenced by motivations and motivations can lead to willingness. The three most common motivations to reduce animal product consumption: animal welfare, the environment, and health were examined to determine whether they predict willingness. A sample of 492 Australian adults completed questionnaires via the Zoho survey platform, and the data underwent a hierarchical regression. Higher pathological selfishness predicted a greater willingness to reduce animal product consumption, as did environmental and animal welfare motivations. However, higher health motivation predicted a lower willingness to reduce animal product consumption. Interpretation of the perplexing results in relation to pathological selfishness suggested further research. The practical value of utilising environmental and animal motivations to increase willingness to reduce animal products whilst bringing attention to the health issues was also discussed. (shrink)

A recent study by McGee from the University of Oregon has led to discussions in international media and on the web. This study addresses an interesting question and applies advanced statistics for its analysis. However, we identify several methodological flaws that invalidate the results. First, McGee tests a hypothesis that does not correspond to his main question and which does not allow McGee to derive the conclusions that are drawn in his paper and reported in the media coverage. Second, the (...) data used are not adequate for the analysis because: i) the dependent variable does not reflect the greenhouse gas emissions characteristics of organic agriculture, ii) the explanatory variables neglect the livestock sector, and iii) trade aspects are missing. Third, McGee fails to discuss his findings in the light of quite a substantial body of experimental, bio-physical research from the US and elsewhere. (shrink)

In this comment I respond to the criticisms put forth by Muller et al. It is my assessment that the authors’ make useful suggestions for future analyses. However, their conclusion regarding the invalidity of my results are based on a misconception of the goals and data used in my article.

In both the academic and societal debates, it is widely assumed that cognitive advertising defenses can reduce children's susceptibility to advertising effects. Empirical evidence supporting this crucial assumption is however missing. It is precisely this gap that the present study aims to fill In a survey of 296 children, we investigate whether children's cognitive defenses reduce the relationship between the amount of television advertising they are exposed to and their desire for advertised product categories. Interaction analysis in regression shows (...) that of all the cognitive defense variables, only understanding advertising's persuasive intent was effective in reducing the impact of advertising exposure on children's advertised product desire. However, this only applies to the older children in the sample. For the younger children, understanding the persuasive intent even increased the impact of advertising. (shrink)

In this paper I discuss ethical issues related to mitigation of climate change. In particular, I focus on mitigation of climate change to the extent this change is caused by livestock production. I support the view—on which many different ethical approaches converge—that the present generation has a moral obligation to mitigate climate change for the benefit of future generations and that developed countries should take the lead in the process. Moreover, I argue that since livestock production is an important contributing (...) factor to climate change, we should undertake mitigation measures also in this sector and not only in, for example, the transport and energy sectors. However, technological solutions do not seem sufficient in the livestock sector, leaving us with the option of reduced meat production and consumption. In order to reach significant results in mitigation of climate change, political steering seems necessary. With this in mind, I argue in favor of a tax on meat consumption. (shrink)

Care work may be connected with emotional and psychological exhaustion but also gratification, reward, and self-empowerment. Caregivers experience both positive and negative emotional states in caring situations, and further studies on the rewarding and energizing aspects of care may help us to broaden our understanding of how we can reduce the degree of burden while increasing the sense of satisfaction. This article shows how the focus on emotion is a necessary step to show the ambivalences and the grey areas connected (...) with the concept of care as well as to challenge the not fully explored assumption that care is often associated with burden and stress and viewed as a result of circumstances. It reports the findings of a micro-situated study of daily care activities among 80 caregivers. Care is seen as a strategic site to grasp deeper insights into the interactional mechanisms through which the emotional dynamics revolving around care produce unanticipated outcomes in terms of symbolic and practical productivity.

Many consumers implicitly associate sustainability with lower product strength. This so-called ethical = less strong intuition (ELSI) poses a major threat for the success of sustainable products. This article explores this pervasive lay theory and examines whether it is a key barrier for sustainable consumption patterns. Even more importantly, little is known about the underlying mechanisms that might operate differently at the implicit and explicit levels of the consumer’s decision-making. To fill this gap, three studies examine how the implicit (...) judgments that consumers activate automatically shape their consumption behaviors, in concert with their more controlled explicit beliefs about sustainable products. The Main Study investigates the ELSI’s imprint on actual shopping patterns and disentangles the implicit and explicit mechanisms of the lay theory. This paper also asks how this negative influence can be attenuated by examining whether the consumer’s interest in sustainable consumption reduces reliance on the ELSI. Two follow-up studies confirm the robustness from different methodological and practical perspectives. Implications for companies and policy makers are derived. (shrink)

Product market competitiveness is positively influenced by the aesthetic value of product form, which is closely related to product complexity. By measuring the cognitive complexity of the product, this research establishes the relationship between the complexity and aesthetics of the product using an artificial neural network. Hence the prediction of product beauty is achieved, which guides design decisions. In this article, the complexity of product form is first measured through a combination of hesitant-fuzzy (...) theory and information axiom. Afterward, the result is weighted by exponential entropy and dimensionally compressed. This method makes data more suitable for the prediction with small samples, obtaining an accuracy improvement of up to 40% compared with traditional approaches. Finally, the importance order of the design elements which affect morphological complexity is acquired. Results show that three of the six complexity features are more significant, impacting the aesthetic feeling of product form. The method increases the attractiveness of products to customers, providing valuable design support for enterprises and designers in the early days when a new product is designed, and reducing research and development risks.

In a review of our work, Kincaid suggests that we are 'productivist', reducing interpretation of Marx and capitalism to production at the expense of the relatively independent role that can be played by the value-form in general and by the money-form in particular. In response, we argue that he distorts interpretation of our work through this prism of production versus exchange, unduly emphasises the independence of exchange to the point of underconsumptionism, and simplistically collapses the mediation between production and exchange (...) in the restructuring that accompanies the accumulation of capital.

Rejection is an essential part of the scholarly publishing process, acting as a filter to distinguish between robust and less credible scientific works. While rejection helps reduce entropy and increase the likelihood of disseminating useful knowledge, the process is not devoid of subjectivity. Providing more informative rejection letters and encouraging humility among editors and reviewers are essential to enhance the efficiency of knowledge production as they help ensure that valuable scientific contributions are not overlooked.

The current work examines how cues traditionally used to signal environmental friendliness, specifically the color green and eco-labels, and influence product efficacy perceptions and subsequent purchase intentions. Across three experiments, we find that environmental cues used in isolation reduce perceptions of product efficacy. We argue that this efficacy discounting effect occurs because the isolated use of an environmental cue introduces category ambiguity by activating competing functionality and environmentally friendly schemas during evaluation. We discuss the implications of our findings (...) for research on environmental consumption as well as offer insight into the effective use of environmental cues on product packaging. (shrink)

We address the problem of musical variation (identification of different musical sequences as variations) and its implications for mental representations of music. According to reductionist theories, listeners judge the structural importance of musical events while forming mental representations. These judgments may result from the production of reduced memory representations that retain only the musical gist. In a study of improvised music performance, pianists produced variations on melodies. Analyses of the musical events retained across variations provided support for the reductionist (...) account of structural importance. A neural network trained to produce reduced memory representations for the same melodies represented structurally important events more efficiently than others. Agreement among the musicians' improvisations, the network model, and music‐theoretic predictions suggest that perceived constancy across musical variation is a natural result of a reductionist mechanism for producing memory representations.

This study employs the Porter hypothesis framework to test the moderating role of production cost in the relationship between resource-efficiency actions and financial performance for German small and medium-sized enterprises (SMEs). For this purpose, we employ the 2012, 2018, and 2021 Flash Eurobarometer surveys to analyze how consistently SMEs adopt resource-efficiency actions, and the impact of these actions on their performance and costs. We also conduct a generalized method of moments regression analysis (GMM). Among the seven resource-efficiency actions proposed, saving (...) water had a significant positive (negative) influence on financial performance in 2012, 2021, and (2018). Saving energy and using renewable energy had a positive and significant (insignificant) effect on financial performance in 2018, 2021, and (2012). Finally, selling scrap material to other companies had a positive and significant impact in all years. Furthermore, increased production costs negatively moderate the relationship between eco-efficiency action scores and financial performance. The results indicate that the “strong” version of the Porter hypothesis is not supported: It only holds when the implementation of eco-efficiency actions reduces production costs and increases financial performance.

Organisations have implemented intensive home-based teleworking in response to global COVID-19 lockdowns and other pandemic-related restrictions. Financial pressures are driving organisations to continue intensive teleworking after the pandemic. Understanding employees’ teleworking inclinations post COVID-19, and how these inclinations are influenced by different factors, is important to ensure any future, more permanent changes to teleworking policies are sustainable for both employees and organisations. This study, therefore, investigated the relationships between the context of home-based teleworking during the pandemic, productivity perceptions during home-based (...) teleworking, and employees’ future teleworking inclinations beyond the pandemic. Specifically, the study examined whether pandemic-teleworking conditions related to the job, and the physical and social environments at home, influenced employees’ FTI, and if perceptions of improved or reduced productivity mediated these relationships. Data were collected during April and May 2020 with a cross-sectional online survey of teleworkers in Germany, Switzerland, the United Kingdom, and other countries during the first COVID-19 lockdowns. Reported FTI were mixed. Most participants reported wanting to telework more post-pandemic compared to before the pandemic; however, 18% wanted to telework less. Hierarchical multiple regression analysis revealed that some teleworking conditions were positively associated with FTI. Other teleworking conditions were not associated with FTI. Perceived changes in productivity mediated the relationship between work privacy fit and FTI. Findings highlight the role of work privacy fit and job demands in influencing pandemic productivity perceptions and teleworking inclinations post-pandemic. Results raise questions about the suitability and sustainability of home-based teleworking for all staff. As organisations plan to increase the proportion of teleworking post-pandemic, this study suggests there is a need to support employees who perceived their productivity to be poor while home-working during the pandemic.

We generalize to theories of modules (complete or not) a result of U. Felgner stating that a complete theory of abelian groups is a Horn theory if and only if it is closed under products. To prove this we show that a reduced product of modules $\Pi_F M_i (i \in I)$ is elementarily equivalent to a direct product of ultraproducts of the modules $M_i (i \in I)$.

Consumers often feel embarrassed when buying products like condoms, hemorrhoid cream, and beriberi cream in crowded pharmacies. There is an interesting phenomenon in life: Some beriberi creams use the images of a “real foot”, while others use the images of a “cartoon foot.” Imagine if a young woman needed to go to a retail store for beriberi cream that would embarrass her, she would choose a “real foot image” or a “cartoon foot image” beriberi cream? It has been shown that (...) the embarrassment of these products has a strong negative impact on consumer buying behavior. Previous researches have explored how changing packaging elements of embarrassing products can effectively reduce consumer embarrassment. However, few have examined the impact of different image types of embarrassing product packaging with embarrassment. Therefore, this research explores the effect of image types on consumers’ willingness to purchase embarrassing products and reveals the mechanisms of the underlying effects. The results show that natural images can lead to lower purchase intention of embarrassing products when the advertisement uses first-person pronouns due to the mediating role played by negative body imagery. However, there is no significant difference in purchase intention between different image types in the third-person pronouns. Finally, this paper discusses its contributions and limitations.

One way to articulate the promise of interdisciplinary research is in terms of the relationship between knowledge and ignorance. Disciplinary research yields deep knowledge of a circumscribed range of issues, but remains ignorant of those issues that stretch outside its purview. Because complex problems such as climate change do not respect disciplinary boundaries, disciplinary research responses to such problems are limited and partial. Interdisciplinary research responses, by contrast, integrate disciplinary perspectives by combining knowledge about different issues and as a result (...) reduce ignorance about more aspects of the problem. In this paper, we develop this idea and argue that while interdisciplinary research can help remediate damaging ignorance about complex problems, it also creates conditions in which other damaging forms of ignorance can arise. We illustrate this point in detail with three case studies before discussing three implications of our analysis for identifying and managing deleterio... (shrink)

Trying to reduce the divide between culture and science, this article follows the producer of popular records, as an interface between music and its market. Like the innovator when he does not obey scientific, technical, and commercial reasons in succession, but reshapes them all together through a double task of giving its form to the product and the interesting people within it, the producer represents the public to the artist and the music to the media. First in a local (...) scale, then in larger and larger ones, alone with the singer, in the studio, and into the media, this sociology of the intermediary shows the producer experimentally organizing, as in a laboratory, a complete production-consumption cycle. Success is then not the mysterious leap to the public, but the last extension of an equation into which the public has been incorporated in many forms from the very beginning. (shrink)

The 2023 edition of the Venice Architecture Biennial Time Space Existence will draw attention to the emerging expressions of sustainability in their numerous forms, ranging from a focus on the environment and urban landscape to the unfolding conversations on innovation, reuse, community, and inclusion. In response to climate change, exhibited projects will investigate new technologies and construction methods that reduce energy consumption through circular design and develop innovative, organic, and recycled building materials. Participants will also address social justice by presenting (...) living solutions envisioned for displaced communities and minorities, while others will examine the tensions between the built urban environment and the nature surrounding it, identifying opportunities for coexistence. Time Space Existence not only aims to be a display but also a living workshop where established and emerging practitioners can work together and present their own visions of the status of architecture and the built environment nowadays. By bringing together ideas from across the world, the exhibition presents itself as a platform for exchange and experimentation and strives to stimulate an engaging dialogue that is inclusive of all voices.

Fermented dairy products such as yogurt contain many bioactive compounds. In addition, probiotic yogurts are an invaluable source of probiotic bacteria and are a group of probiotic products best accepted by children. There is plenty of research indicating an interdependence between yogurt consumption, body mass index, and adipose tissue percentage, which suggests that yogurt consumption may contribute to reducing the risk of becoming overweight or obese. In turn, the occurrence of overweight and obesity may be accompanied by a reduced (...) sensitivity to sweetness, which modifies food preference selection and acceptance, including with yogurt. This study aimed to assess the preferences and consumption of yogurt in terms of sensitivity to recognize sweetness and obesity in a group of 7–9-year-old children. Body mass index and adipose tissue percentage obesity indicators were determined, and the frequency of fermented milk product consumption was assessed about the results of the sweetness recognition test as well as yogurt preferences. There was no significant relationship between body weight and the frequency of fermented milk product consumption. Correlations were found between the values of body mass index and the ability to recognize sweetness, which was significantly better recognized by underweight children or at normal body weight, moreover, those children with a higher ability to recognize sweetness significantly more frequently preferred plain unsweetened yogurt.

This project is an attempt to frame and develop the questions: What is the relation between the economy, what Marx called the mode of production, and transformations of subjectivity and social relations? How is it possible to think these relations without reducing one to the other, or effacing one for the sake of the other? In short, how can we think the materiality of subjectivity? Several different discourses and lines of research provoke these questions. First, recent and not so recent (...) work within continental philosophy in relation to the "critique of the subject," argues for an investigation of the practices of knowledge, power, and desire productive of historically determinate forms of subjectivity. The second line of research includes a history of heterogeneous Marxist thinkers all of whom attempt to locate in Marx's texts a series of questions, largely unresolved, regarding the relations between production and power, politics and the economy, culture and materiality. To identify these two discourses as provocations, however, is not to suggest that what is at stake in this project is the simple adjudication, or settling of accounts, between Marxism and post-structuralism---a question which would only be of interest to a handful of academics. Rather the investigation into these two lines of research has as its framework a larger and somewhat inchoate series of questions regarding the contemporary socio-historical condition. These questions all begin from the intuition that contemporary society, what is called "post-industrial," "postmodern," or "information society," entails a fundamental transformation of the relations, or an accelerated breakdown of the divisions, between the spheres of the economy, culture, politics, and subjectivity. I argue that these questions, and the current juncture which they attempt to grasp, can be clarified through an articulation of the complex relation between the mode of production and the production of subjectivity; such an articulation takes the form of a genealogy of various critical junctures in the writing of Marx, the debates within western Marxism and critical theory, and contemporary continental philosophy.

Chile needs to diversify its energy supply, and should establish policies that encourage the production and use of biofuels. The demand for energy resources increases with population growth and industrial development, making it urgent to find green alternatives to minimize the impacts of greenhouse gas emissions of traditional fuels. However, it is required that sophisticated strategies consider all externalities from the production of biofuels and should be established on the basis of protecting the environment, reducing GHG emissions and to avoid (...) violating human rights. This article presents the Chilean reality, based on ethical principles that should be guarded to regulate the bioenergy market. These principles are: human rights, environmental sustainability, climate change mitigation, right to a fair reward, and equitable distribution. It is concluded that in Chile the concentration of land and water for the development of extractive industries; and for agricultural and forestry purposes, contradicts the principle of human rights. The unequal distribution of income is also highlighted as part of a cycle of social injustice, with a high Gini coefficient . However, the policy of biofuels can be strengthened with the early use of second generation feedstock, the introduction of fair trade and regulation by the state to encourage participation of small farmers, and allows a position for Chile at the forefront of bioenergy production.

Poultry production makes a substantial contribution to global food security, providing energy, protein, and essential micro-nutrients to humans. Modern intensive poultry farming systems are challenged by the evolution of Highly Pathogenic Avian Influenza strains. The presence of avian influenza in poultry flocks poses a significant risk of an avian origin influenza that is easily transmittable between human beings evolving. By reducing contact between humans and fowl, the use of automation in poultry production has the potential to improve biosecurity and thus (...) reduce the risk of pandemic influenza. Many poultry facilities are already highly automated. The rapid rate of progress in robotics and AI suggests that “lights out”—fully automated—poultry production systems may soon be possible. In this paper we consider the ethical and policy issues that would be raised by lights-out poultry production. There is a strong animal and human welfare case for reducing the risk of pandemic influenza via increased use of automation. However, lights-out farming looks to be the ultimate endpoint of dynamics already present in industrial agriculture, which led to the dangers of zoonotic infection from animal agriculture in the first place. Whether nations should respond to that risk by doubling down on industrial models of animal production and embracing fully automated farms or by reconsidering the current model of animal agriculture altogether is, we suggest, both the most important, and the most difficult, question posed by the prospect of lights out farms.

The mammalian blastocyst exhibits a high capacity for aerobic glycolysis, a metabolic characteristic of tumours. It has been considered that aerobic glycolysis is a means to ensure a high carbon flux to fulfil biosynthetic demands. Here, alternative explanations for this pattern of metabolism are considered. Lactate creates a microenvironment of low pH around the embryo to assist the disaggregation of uterine tissues to facilitate trophoblast invasion. Further it is proposed that lactate acts as a signalling molecule (especially at the (...) class='Hi'>reduced oxygen tension present at implantation) to elicit bioactive VEGF recruitment from uterine cells, to promote angiogenesis. Finally it is suggested that the region of high lactate/low pH created by the blastocyst modulates the activity of the local immune response, helping to create immune tolerance. Consequently, the mammalian blastocyst offers a model to study the role of microenvironments, and how metabolites and pH are used in signalling. (shrink)

Throughout the twentieth century, critical art history often chose to ally itself with a restrictive brand of formalism. As a result, representation- and ideology-critical analyses regularly reduced the artwork to the bare bones (Hegel) of the material signifier in its social use. By contrast, in the texts assembled here, elements of a critical materialism are combined with an effort to reevaluate the meta-physical implications of modern abstraction and art since the 1960s. Taking Gilles Deleuze s readings of Spinoza, Nietzsche, (...) and Bergson as his starting point, the author delineates a topic in which the artwork s capacity for resistance is grounded in its relationship to an immanent infinity: the Spinozian substance, Nietzsche s Becoming, Bergson s duree. Against the backdrop of a critical rereading of Heidegger, this infinite dimension is interpreted in temporal and ontological terms as the vertical past of production, which can only be grasped in broken and technically encrypted form in the present shape and materiality of the artwork. Hence the notion of an aesthetics of production does not imply a nostalgia for the artisanal or for the artwork s singularity. The concept of production developed in this book aims at a realm that lies beyond finite representation but is still understood in materialist terms, and that threatens the circulation of positive, conceptually standardized knowledge. In case studies on Piet Mondrian, Marcel Duchamp, Thomas Hirschhorn, and Michael Asher and in framing essays on Kant and Nietzsche as well as Heidegger and Spinoza, this book articulates a concept of the artwork in the long modern era which takes account of the twentieth century s critique of metaphysics but without surrendering the truth claim of art and philosophy in favor of a culturalist and sociological relativism.
