To a large extent and one that is highly structuring, energy choices that are made in a society are political choices. This article aims at studying how these choices can be redirected by technological developments associated with renewable energy, thus contributing to a redistribution of opportunities and correspondingly to social reorganizations. In order to show that the development of alternative energies not only depends on technological advances but can also, in the process, reveal political potentialities, three steps are proposed. (...) The first step will clarify the theoretical arguments in favor of an approach in terms of “technological potentialism.” Second, we will extend this approach by identifying a set of potentialities linked with renewable energies and the model that could arise from these alternative forms or approaches. Finally, we will examine how these potentialities could find paths to become effective. (shrink)

Based upon the work of C. H. Douglas, this paper explores the role of debt in the economy. In the 1920s Douglas observed the workings of financial mechanisms within the real economy, noting that they could be modified to achieve a socially and ecologically sustainable economics of sufficiency. Douglas' exploration of the role of debt in the economy accords well with Veblen's institutional analysis, while his writing reverberates with Veblenian terminology. As an economist, Douglas is both intuitive and eclectic, and, (...) as Mehta observes, ‘no writer in economics has made his thought so opaque to the reader.’ Nevertheless, Douglas' rejection by orthodoxy was due in no small measure to the impracticality of tailoring his theoretical observations within the constraints of neo-classical general free market equilibrium theory. Although they gave rise to a widespread popular movement, Douglas' proposals for debt-free finance of production could not be accommodated within economic orthodoxy. (shrink)

Morphophonological alternations, such as the voicing alternation that arises in a morphological paradigm due to final-devoicing in Dutch, are notoriously difficult for children to acquire. This has previously been attributed to their unpredictability. In fact, the presence or absence of a voicing alternation is partly predictable if the phonological context of the word is taken into account, and adults have been shown to use this information ( Ernestus and Baayen, 2003 ). This study investigates whether voicing alternations are predictable from (...) the child’s input, and whether children can make use of this information. A corpus study of child-directed speech establishes that the likelihood of a stem-final obstruent alternating is somewhat predictable on the basis of the phonological properties of the stem. In Experiment 1 Dutch 3-year-olds’ production accuracy in a plural-elicitation task is shown to be sensitive to the distributional statistics. However, distributional properties do not play a role in children’s sensitivity to mispronunciations of voicing in a Preferential Looking Task in Experiment 2. (shrink)

Much of early western research has focused on identity. A primed identity can inhibit the priming of other alternative identities, and also negatively affect the intention to purchase products related to those alternative identities. In western culture, individuals operate within a cultural framework that makes them more likely to prioritize their own goals and less likely to rely on environmental factors when evaluating others. Individuals are more likely to choose products that fit their primed identity. In this study, (...) we suggest that in collectivist Chinese culture, individuals may give priority to group-level goals and attach more importance to situational factors when evaluating others. Therefore, a primed identity may not necessarily inhibit the priming of alternative identities. In this research, we examine the association between a focal identity and alternative identities, with particular emphasis on the accessibility, discrepancies, and effects on purchase intention of alternative identities. We also examine the intent to purchase products related to the alternative identity vs. the focal identity, developing a model with which to explore this construct. We test four hypotheses through experiments using an online questionnaire and analyzing the resulting data using statistical product service solutions 22.0 and the PROCESS macro modeling tool. The results are as follows: First, the association between a focal identity and alternative identity has a positive impact on the accessibility of the alternative identity. The clearer the alternative identity is, the greater the impact of the association between the focal identity and alternative identity on the latter’s accessibility. Second, the accessibility of the alternative identity has a positive impact on the intent to purchase alternative identity vs. focal identity-related products. The greater the discrepancy between the focal identity and the alternative identity, the greater the impact on the intent to purchase alternative identity vs. focal identity-related products. The results of this study confirmed the interaction between identity association and the clarity of the alternative identity, as well as the influence of the accessibility of the alternative identity on the intent to purchase alternative identity vs. focal identity-related products. We contribute to the development of a theory on intention to purchase identity-related products. (shrink)

Two university English seminars were video-recorded to provide data for a pilot project investigating how English is produced or 'actualized' in teaching and learning encounters. The project is positioned within three contexts: national policy about higher education teaching; current research about higher education pedagogy; and, the history and politics of university English. The main aim of the article is to explicate a methodology that takes as its data actual moments of teaching, captured on video tape, and the teachers' commentary on (...) them. It analyses these records with reference to theories about rhetoric. (shrink)

A key focus for agri-food scholars today pertains to emerging “alternative food movements,” particularly their long-term viability, and their potential to induce transitions in our prevailing conventional global agri-food systems. One under-studied element in recent research on sustainability transitions more broadly is the role of disruptive events in the emergence or expansion of these movements. We present the findings of a case study of the effect of a sudden acute food safety crisis—bovine spongiform encephalopathy, or mad cow disease—on (...) class='Hi'>alternative beef production in the Province of Alberta, Canada. Employing the conceptual lens of Sustainability Transition Theory, we explore the perspectives of conventional and alternative beef producers, treating alternative beef production as a niche operating within the dominant regime of global industrial agri-business. Three key findings are presented here. First, food safety risks and disruptive events can emerge as a direct consequence of the socio-ecological contradictions embedded in industrial agriculture, representing an opportunity for expansion of agricultural niches. Second, certain features of socio-economic regimes can also contribute to niche emergence, such as an economic system that disenfranchises beef-producing families. Finally, our study highlights the high level of diversity among niche agents and the complex and nuanced nature of their support for the niche. (shrink)

The meaning of alternating formation is the one that has been built, day after day, by the author who is working as teacher-researcher. The hyphen here stands for the link between two concrete exercices of the daily writing experience. Six processes have been revealed in two steps : those which are the pilar of this alternative smart teaching method (production, transaction and cooperation) and those which are hidden and secretly bring life to the first setting (integration, authorization and (...) emancipation). Their complex articulation opens an alternate way to learn, teach and be shaped as a subject to find a problematic that has a meaning for us and then enable us to be seen by ourself as a social character in a structure or an organisation. Allow an original intelligence can enable each of us to draw a smart contour to find our place as a social character. (shrink)

The past decades’ substantial growth in globalized meat consumption continues to shape the international political economy of food and agriculture. This political economy of meat composes a site of contention; in Brazil, where livestock production is particularly thriving, large agri-food corporations are being challenged by alternative food networks. This article analyzes experiential and experimental accounts of such an actor—a collectivized pork cooperative tied to Brazil’s Landless Movement—which seeks to navigate the political economy of meat. The ethnographic case study (...) documents these livestock farmers’ ambiguity towards complying with the capitalist commodification process, required by the intensifying meat market. Moreover, undertaking an intersectional approach, the article theorizes how animal-into-food commodification in turn depends on the speciesist logic, a normative human/non-human divide that endorses the meat commodity. Hence the article demonstrates how alternative food networks at once navigate confines of capitalist commodification and the speciesist logic that impels the political economy of meat. (shrink)

Providing efficient and clean power is a challenge for devices that range from the micro to macro in scale. Although there has been significant progress in the development of micro-, meso-, and macro-scale power supplies and technologies, realization of many devices is limited by the inability of power supplies to scale with the diminishing sizes of CMOS-based technology. Here, the authors provide an overview of piezoelectric energy harvesting technology along with a discussion of proof of concept devices, relevant governing equations, (...) and figures of merit. They present two case studies: (a) energy capture from the operation of a novel shear and elastic modulus indentation device subjected to applied voltage and (b) energy capture from vibrating commercial bimorph piezoelectric structures mounted on household appliances. Lastly, areas of development needed for realization of commercial energy harvesting devices are suggested. (shrink)

This study examines the hydrolysis of lignocellulose extracted from poultry manure for the purpose of investigating low-cost feedstocks for ethanol production while providing an alternative solid waste management strategy for agricultural livestock manures. Poultry manure underwent various pretreatments to enhance subsequent enzymatic hydrolysis including untreated, alkaline pretreatment with 0.5N KOH, drying, and grinding. The KOH-treated, dried, and grinded poultry manure yielded the highest glucose conversions. When poultry manure without pretreatment was hydrolyzed at 40°C with an enzyme loading 400 (...) units/g feedstock, 7.1 ± 0.3% was converted to glucose in 24 hours. This increased to 27.6 ± 1.2% when a KOH pretreatment followed by drying and grinding was applied. Fourier transform infrared spectroscopy analyses were used to examine differences in the composition of the pretreated feedstock before and after enzymatic hydrolysis. These indicate that the cellulose content in pretreated poultry manure was removed during enzymatic hydrolysis. (shrink)

It is widely suggested that a eukaryotic mRNA typically contains one translation start site and encodes a single functional protein product. However, according to current points of view on translation initiation mechanisms, eukaryotic ribosomes can recognize several alternative translation start sites and the number of experimentally verified examples of alternative translation is growing rapidly. Also, the frequent occurrence of alternative translation events and their functional significance are supported by the results of computational evaluations. The functional role of (...) alternative translation and its contribution to eukaryotic proteome complexity are discussed. BioEssays 30:683–691, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

The input to phonological reasoning are alternations, that is, variations in the pronunciation of related words, such as in electri[k] ‐ electri[s]‐ity. But phonologists cannot agree what counts as a relevant alternation: the issue is highly contentious despite a research record of over 50 years. We believe that the experimental setup presented may contribute to this debate based on a kind of evidence that was not brought to bear to date. Our experiment was thus designed to distinguish between alternations where (...) phonological computation plays no role, and those where it has contributed to language production. The design manipulates two factors that to date have not been considered in experimental studies of language production: linguistic complexity and alternation specificity. The former is understood as extra processing demands issued by two types of linguistic activity, morphosyntactic and phonological. Our results show that reaction time latencies are longer when participants are burdened with both morphosyntactic and phonological tasks than when they carry out just a morphosyntactic task, and they are still shorter in absence of both types of demands. These results allowed us to address alternation specificity, that is, the fact that different alternations (within a language or across languages) may be driven by different production routines (an idea that is consensual among linguists but underdeveloped in the psycholinguistic literature). Our study shows that four different alternations in French produce alternation‐specific signatures in reaction time latencies. These findings may thus redound to the advantage of psycholinguistic studies by identifying two new factors, as well as produce results that speak to the linguistic quarrels. (shrink)

Consumers’ actual knowledge about modern food production is limited, and their judgment is often guided by assumptions or associations that are not necessarily in line with reality. Consumers’ rather unrealistic idea of livestock farming is driven by beautiful and romanticized pictures in advertising. If confronted with the reality of modern livestock farming, consumers’ responses are mainly negative. So far, dairy farming still has a more positive image and thus is less affected by public criticism. However, if made public, some (...) of the current production practices in dairy farming have the potential to reduce consumer acceptance which in turn can have a tremendous effect on farmers. A particularly urgent topic is the handling of male dairy calves. Such calves are often treated as surplus animals due to their low genetic merits for meat, with the risk of resulting in the deprivation of animal welfare. To maintain consumer acceptance of dairy products and find socially accepted alternatives for the handling of male calves, insights into consumer perception of current and future production practices in dairy farming are needed. Thus, the aim of this study is to analyze how consumers evaluate the current situation of male dairy calves and alternatives in male calf management. A quantitative online survey, representative for the German population in terms of gender, age, education, region, and income, was carried out with 1 194 participants in February 2022. Overall, 60% of participants were not aware of the fact that male dairy calves are less appropriate for fattening purposes. Respondents saw a clear need for alternative methods for handling male calves from dairy production. More, our results show that the use of sexed semen encounters consumer resistance, while other alternatives that were evaluated as more natural were more accepted. A cluster analysis identified 3 distinct consumer segments labelled “sexed semen opponents” (31.6%), “undecided” (30.4%), and “proponents of all alternatives” (38.0%) that differed in their acceptance of alternative handling practices of male dairy calves. The results emphasize the gap between consumers’ expectations and reality on farms and the importance of considering consumer preferences when developing future pathways for dairy farming. (shrink)

The Anthropocene is characterized by multiple crises associated with the infinite accumulation of growth on a planet of finite resources. Productive labour and the 8-h working model contribute to this contradiction. We argue for the reduction of productive labour in favour of reproductive labour accumulated through practices of collective care. The latter can heal the damage capital accumulation produces. Collective care brings into light various social practices often invisible to production, allows for a new understanding of nonhuman agency, and (...) challenges the dominant ethical disposition around work. We advocate for a new power equilibrium between productive and reproductive labour. (shrink)

How can we understand and move beyond a persistent tendency to think, write and organize about food and agriculture as if it were possible to separate a theorist’s views on gender and race from their views on farm animals? Considerable scholarship already addresses this question. This paper suggests that philosophy can contribute to the discussion by focusing a particular kind of attention on patterns of thinking. In particular, dichotomous thinking has traditionally provided grounds for separating production from consumption, and (...) continues to present an obstacle to efforts at connecting “farm issues” to “fork issues.” Three characteristics of dichotomous thinking present particular obstacles to scholarship that would deeply integrate food studies with agriculture studies. (1) Dichotomies tend to set up not just a contrast but an antagonism between their two poles, such that to be this means to be not that. (2) Dichotomous thinking tends to erase nuance, to eliminate anything between the two dichotomous options, and to purify or “clean up” the ambiguous case or extraneous material, by shoehorning it into one option or the other; and (3) Particular groups of dichotomies operate together, such that they mutually reinforce each other to create a way of understanding the world that is more plausible because of its cohesiveness. These snarls of mutuallysupportive dichotomies that are nevertheless purist and puritanical in their impact, present a real (i.e. ideological, theoretical, conceptual) challenge to creating scholarly and activist movements that integrate the best of agrarian thinking and the best of critical food studies scholarship attentive to race, class and gender oppression.

Rational accounts of language use such as the uniform information density hypothesis, which asserts that speakers distribute information uniformly across their utterances, and the rational speech act (RSA) model, which suggests that speakers optimize the formulation of their message by reasoning about what the comprehender would understand, have been hypothesized to account for a wide range of language use phenomena. We here specifically focus on the production of discourse connectives. While there is some prior work indicating that discourse connective (...) production may be governed by RSA, that work uses a strongly gamified experimental setting. In this study, we aim to explore whether speakers reason about the interpretation of their conversational partner also in more realistic settings. We thereby systematically vary the task setup to tease apart effects of task instructions and effects of the speaker explicitly seeing the interpretation alternatives for the listener. Our results show that the RSA-predicted effect of connective choice based on reasoning about the listener is only found in the original setting where explicit interpretation alternatives of the listener are available for the speaker. The effect disappears when the speaker has to reason about listener interpretations. We furthermore find that rational effects are amplified by the gamified task setting, indicating that meta-reasoning about the specific task may play an important role and potentially limit the generalizability of the found effects to more naturalistic every-day language use.

Why does one need creativity? On a personal level, improvisation with available resources is needed for online coping with unforeseen environmental stimuli when existing knowledge and apparent action strategies do not work. On a cultural level, the exploitation of existing cultural means and norms for the deliberate production of novel and valuable artifacts is a basis for cultural and technological development and extension of human action possibilities across various domains. It is less clear, however, how creativity develops and how (...) exactly one arrives at generating new action possibilities and producing multiple alternative action strategies using familiar objects. In this theoretical paper, we first consider existing accounts of the creative process in the Alternative Uses Task and then present an alternative interpretation, drawing on sociocultural views and an embodied cognition approach. We explore similarities between the psychological processes underlying the generation of new uses in the Alternative Uses Task and children’s pretend play. We discuss possible cognitive mechanisms and speculate how the generation of new action possibilities for common objects in pretend play can be related to adults’ ability to generate new action strategies associated with object use. Implications for creativity development in humans and embodied artificial agents are discussed. (shrink)

Calhoun is interviewed regarding the relationship of his work on the university to his other research interests. Calhoun elaborates on his hope for a debate over transformations in the structure of the university that is much more sensitive to the public role universities play and the importance of the collective goods they create.

By situating universities in relationship with the public sphere, Calhoun provides a basis for debates about the transformation of the university to overcome the structured and structuring dispositions of the participants, while remaining grounded in social and historical analysis-an approach that can be considered an alternative public sociology.

Unlike the French state, which has regulated both the hijab and niqab through national legislation, the American liberal framework utilizes a laissez-faire approach, which relies on a range of public and private institutions to determine acceptable public presentations of the liberal female (...) subject. I refer to this form of management as "neoliberalism." Neoliberalism management works in conjunction with popular political discourses and domestic events in ways that alternately contract and expand the boundaries that allow "suitable Muslim women" in the public sphere.

Alternative splicing is a well‐characterized mechanism by which multiple transcripts are generated from a single mRNA precursor. By allowing production of several protein isoforms from one pre‐mRNA, alternative splicing contributes to proteomic diversity. But what do we know about the origin of this mechanism? Do the same evolutionary forces apply to alternatively and constitutively splice exons? Do similar forces act on all types of alternative splicing? Are the products generated by alternative splicing functional? Why is (...) “improper” recognition of exons and introns allowed by the splicing machinery?

Human eggs for basic, fertility and stem-cell research are in short supply. Many experiments that require their use cannot be carried out at present, and, therefore, the benefits that could emerge from these are either delayed or never materialise. This state of affairs is problematic for scientists and patients worldwide, and it is a matter that needs our attention. Recent advances in chimera research have opened the possibility of creating human/non-human animal chimeras intended for human gamete production (chimeras-IHGP). In (...) this paper, I examine four arguments against the creation of such chimeras and prove that all of them are found wanting. I conclude by showing that there is a strong moral reason for scientists to pursue this research avenue. (shrink)

Alternative splicing allows for the production of many gene products from a single coding sequence. I introduce the concept of alternative splicing via some examples.

Hypotheses such as these bring into question our working concepts of the gene. I examine several gene concepts introduced (...) to cope with processes such as alternative splicing. Next I introduce some hypotheses about the evolution of mechanisms alternative splicing in higher organisms.

Third-party certification is an increasingly prevalent tactic which agrifood activists use to “help” consumers shop ethically, and also to reorganize commodity markets. While consumers embrace the chance to “vote with their dollar,” academics question the potential for labels to foster widespread political, economic, and agroecological change. Yet, despite widespread critique, a mounting body of work appears resigned to accept that certification may be the only option available to activist groups in the context of neoliberal socio-economic orders. At the extreme, Guthman (...) (Antipode 39(3): 457, 2007) posits that “at this political juncture… ‘there is no alternative.” This paper offers a different assessment of third-party certification, and points to interventions that are potentially more influential that are currently available to activist groups. Exploring the evolution of the Non-GMO Project—a novel certification for foods that are reasonably free of genetically engineered (GE) material—I make two arguments. First, I echo the literature’s critical perspective by illustrating how certification projects become vulnerable to industry capture. Reviewing its history and current context, I suggest that the Non-GMO Project would be better suited to helping companies avoid mounting public criticism than to substantially reorient agrifood production. Second, I explore the “politics of the possible” in the current political economy and argue that while neoliberalization and organizers’ places within the food system initially oriented the group towards the private sector, the choice to pursue certification arose directly from two industry partnerships. Consequently, current trends might favor market mechanisms, but certification is only one possible intervention that has emerged as a result of particular, and perhaps avoidable, circumstances. The article offers tentative delineation of alternatives ways that activists might intervene in agrifood and political economic systems given present constraints. (shrink)

Alternative pre‐mRNA splicing leads to distinct products of gene expression in development and disease. Antagonistic splice variants of genes involved in differentiation, apoptosis, invasion and metastasis often exist in a delicate equilibrium that is found to be perturbed in tumours. In several recent examples, splice variants that are overexpressed in cancer are expressed as hyper‐oncogenic proteins, which often correlate with poor prognosis, thus suggesting improved diagnosis and follow up treatment. Global gene expression technologies are just beginning to decipher the (...) interplay between alternatively spliced isoforms and protein‐splicing factors that will lead to identification of the mutations in these trans‐acting factors responsible for pathogenic alternative splicing in cancer.

ABSTRACTThis article reveals how nineteenth-century chemists and health reformers tried to eradicate the use of yeast in bread, claiming they had devised healthier and more sanitary ways to raise bread. It describes the alternative technological solutions to baking bread, investigating factors that influenced their development and adaptation in the marketplace. A lack of scientific and cultural consensus surrounding yeast, what it was and what it did, fermented during this period. The conflict over yeast helped create a heterogeneous industrialization of (...) the baking industry, changing processes and ingredients and creating new forms of bakery products. By examining the claims of promoters of rival scientific beliefs and technologies, as well as those of users and social commentators, we can see that technology’s eventual adaptation and impact on society is not predictable at its outset. Exploring the relationship between differing scientific beliefs, cultural understandings and alternative technologies also shows how science and industry cannot be isolated from their social and cultural context. The examination of the nineteenth-century technological development of commonplace commodities such as bread, baking powder and yeast, also reveals and explores a story that has not been told before in the history of science and technology. Why it has not been told is as enlightening as the story itself, revealing as it does our own privileging of what is important in science and history. (shrink)

To what extent does the ethicality of an advertisement depend on the good or service being advertised? This question has engaged business ethicists for decades. Some say that an ad for something good is always good, while an ad for something bad is always bad. Others insist that advert-evaluation and product-appraisal are entirely independent of one another—the ethics of selling has nothing to do with what is being sold. In this paper I add another dimension to the debate. I do (...) this not by offering an alternative answer to the question, but by inverting the questions itself. I ask: To what extent does our moral assessment of advertising influence our moral evaluation of particular products? I hope to show that one’s general attitude towards advertising invariably colours one’s appraisal of particular goods and services. If advertising is seen as a morally objectionable enterprise, products which may seem innocuous start to look not only useless, but baneful and corrupting. If advertising is seen as a morally, psychologically and socially valuable activity, the same innocuous products start to look fulfilling, enriching, and overall life-enhancing. (shrink)

When learning a new math concept, should learners be first taught the concept and its associated procedures and then solve problems, or solve problems first even if it leads to failure and then be taught the concept and the procedures? Two randomized-controlled studies found that both methods lead to high levels of procedural knowledge. However, students who engaged in problem solving before being taught demonstrated significantly greater conceptual understanding and ability to transfer to novel problems than those who were taught (...) first. The second study further showed that when given an opportunity to learn from the failed problem-solving attempts of their peers, students outperformed those who were taught first, but not those who engaged in problem solving first. Process findings showed that the number of student-generated solutions significantly predicted learning outcomes. These results challenge the conventional practice of direct instruction to teach new math concepts and procedures, and propose the possibility of learning from one's own failed problem-solving attempts or those of others before receiving instruction as alternatives for better math learning.

Public’s concern about poor animal welfare provided by intensive farming systems has increased over the last decades. This study reviewed the interest of the scientific research on the pain issue in pig production to assess if the societal instances may be a driving force for the research activity. A literature search protocol was set up to identify the peer-reviewed papers published between 1970 and 2017 that covered the topic of ‘pain in pigs’ using Scopus®, database of Elsevier©. One hundred (...) and thirty papers were selected and they were mainly focused on the practice of castration followed by tail docking. The scientific community first focused on these painful practices as a way to improve production efficiency and quality issues while more recently, due to the increased pressure by the public opinion, turned its interest towards the search of alternative solutions. A text mining analysis on the abstract of the selected papers clearly indicated the effort of the research to explore solutions to alleviate pain. Evocative words of this target were the selected terms ‘pharmacological analgesic’ and ‘anaesthetic treatments’. The text mining highlighted vocalizations as the main pain indicators in pigs as this term was frequently associated to ‘acute stress’. Ethical issues were a minor research topic in the scientific literature on pig breeding but in the short run, they are supposed to become a major subject to justify the acceptance of the modern production systems at the eyes of the consumers.

This article introduces a new model of the relationship between growth and learning and tests a set of hypotheses related to the development of adult competency using time allocation, anthropometric, and experimental task performance data collected between 1992 and 1997 in a multiethnic community in the Okavango Delta, Botswana. Building on seminal work in life history theory by Hawkes, Blurton Jones and associates, and Kaplan and associates, the punctuated development model presented here incorporates the effects of both growth and learning (...) constraints on age-specific task performance. In addition, the payoff to investment in two forms of embodied capital, growth-based and learning-based, are examined in relation to features of the socioecology, including subsistence economy and family composition.The three main findings are:The development of adult competency in specific tasks entails a steplike relationship between growth- and experience-based forms of embodied capital in the ontogeny of ability acquisition.There is a trade-off between the acquisition of experience-based embodied capital in the form of skills and knowledge and immediate productivity among children. Time allocation to these alternatives is primarily determined by the short- and long-term costs and benefits to parents of investment in children’s embodied capital.The availability of laborers and the overall labor requirements of the household are major determinants of investment in alternate forms of embodied capital and resulting variation in children’s time allocation. The value of children’s labor to their parents is dependent upon the opportunity costs to engaging in other activities not only for the child in question but also for potential substitute laborers.These results have important implications for our understanding of the role of growth and learning in the evolution of the human juvenile period, as well as for our understanding of cross-cultural variation in child growth and development and patterns of work and play.

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 (...) 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)

A further critique of Fine and Saad-Filho's reading of Marxist political economy: it neglects the monetary dimension of Marx's analysis; it focuses too much on production, and on the organic composition of capital, treated in isolation from the overall circuit of capital. An alternative theorisation is proposed, stressing what will now be called emergence patterns in Marx's value theory, and giving due weight to circulation, realisation, competition and capital allocation.

A major strategy in the creation of sustainable economies is the establishment of alternative market institutions, such as fair trade and local market systems. However, the dynamics of these alternative markets are poorly understood. What are the rules of behavior by which these markets function? How do these markets maintain their separate identity as “alternative”: apart from the conventional (“free”) market system? Building on Lyson’s notion of civic agriculture, we argue that alternative markets maintain themselves through (...) civic engagement. However, we argue that the civically-engaged practices of alternative markets are poorly understood. We seek, therefore, to begin a conversation about the everyday forms of civic engagement in alternative practice and to do this we introduce a few useful conceptual tools. Building upon ideas in science studies about the collaboration of scientists (Hess, Alternative pathways in science and industry, 2007) we argue that civic markets have their own “market fields” and “modes of governance” (Bulkeley et al., Environment and Planning A 39:2733–2753, 2007), their own fields of social interaction in which rules of behavior become stabilized and determine how the market works. The creation of a social field also requires the demarcation of boundaries, referred to in the science studies literature as “boundary work” (Gieryn, Cultural boundaries of science: Credibility on the line, 1999). We apply the idea of boundary work to understand how alternative market actors maintain boundaries between alternative and conventional markets. Finally, studies of collaboration in science have often centered on the object created through these interactions, an object that is partially material and partially a product of knowledge, what (Rheinberger, Toward a history of epistemic things: Synthesizing proteins in the test tube, 1997) calls an “epistemic object.” We use this idea to understand that the creation of alternative objects of exchange, such as organic food, are epistemic objects in that they combine both particular materialities and particular ways of knowing. Using these concepts, we will carry out a close analysis of the mode of governance in the national organic market, looking specifically a recent governance crisis in organic agriculture known as the Harvey lawsuit.

Promotion of fair tradebananas in Europe has achieved impressive initialgains on (...) the consumer end of the commodity chain,capturing 10 percent or more of the banana trade inseveral countries. Yet in spite of these gains, thefair trade banana initiative appears to beencountering serious obstacles to its further success.We argue that the primary challenge in creating atruly alternative trade in bananas stems from thedifficulties of upholding rigorous social andenvironmental standards in the face of increasinginroads into fair trade markets by transnationalcorporations producing under less rigorous conditions.We then develop a series of options for strengtheningfair trade banana initiatives in both Europe and NorthAmerica. We conclude by arguing that the case ofbananas illuminates the general question of how toachieve more progressive and sustainable productionand consumption systems within a global system thatdrives production and consumption toward greaterintegration and homogenization under the control oftransnational corporations.

Motion pictures, from their emergence in the late nineteenth century, have been used in ways that have held in tension a number of competing or seemingly contradictory impulses. Movies can document and reveal physical and social realities, extend perception through time and space, and create audio-visual approximations of subjective perspective and mental states; they can mimic or transform reality, or create new verisimilar or fantastical screen worlds that, in part, resemble, or abstract our own. Over the past 120 years, many (...) thinkers have attempted to define the aesthetic nature of the medium in, at times, prescriptive or overly conditional ways that centre on some technologies (notably the camera), techniques, or types of motion picture making while excluding others (notably animation), and that bracket or narrowly circumscribe the question of viewer experience. However, in the past thirty years or so, we have seen an expanded interest in forms previously more marginalized in film studies, such as documentary, docudrama, and animation. This is due in part to the digital turn in both screen media production and distribution, which has led to the proliferation and pervasiveness of both. We have also seen much deeper consideration of how viewers understand, experience, and think with screen media with the rise of phenomenological and cognitive approaches to the screen-viewer relationship. Carl Plantinga has become a key and productive figure during these years, generating persuasive understandings of the emotional, schematic, and moral dimensions of our experience of screen media, and the ways in which films and TV are designed for such purposes. A cognitivist, he is interested in the possibilities of the screen to allow us to better imagine and empathize with the experiences of others, to persuade us of a state of affairs, and to provoke our capacity for moral reasoning.

There is a widespread consensus that a commodification of body parts is to be prevented. Numerous policy papers by international organizations extend this view to the blood supply and recommend a system of uncompensated volunteers in this area—often, however, without making the arguments for this view explicit. This situation seems to indicate that a relevant source of justified worry or unease about the blood supply system has to do with the issue of commodification. As a result, the current health minister (...) of Ontario is proposing a ban on compensation even for blood plasma—despite the fact that Canada can only generate 30 % of the plasma needed for fractionation into important plasma protein products and has to purchase the rest abroad. In the following, I am going to suggest a number of alternative perspectives on the debate in order to facilitate a less dogmatic and more differentiated debate about the matter. Especially in light of the often over-simplified notions of altruism and commodification, I conclude that the debate has not conclusively established that it would be morally objectionable to provide blood plasma donors with monetary compensation or with other forms of explicit social recognition as an incentive. This is especially true of donations for fractionation into medicinal products by profit-oriented pharmaceutical companies. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 37.1 (2004) 92-95 [Access article in PDF] Rethinking the Frankfurt School: Alternative Legacies of Cultural Critique. Ed. Jeffrey T. Nealon and Caren Irr. Albany: SUNY Press, 2002. Pp. 227. $23.95, paperback. Not long ago at a gathering of arts and humanities scholars, I found myself introduced to a group of people as someone interested in the work of Theodor Adorno, whose name led one member (...) of the group to groan, "Not that old chestnut!" Such has been an ambient attitude in cultural studies toward not just the work of Adorno but many of the scholars who came to be known collectively in the 1960s as the Frankfurt School, thanks to their affiliation with the Institute for Social Research at the University of Frankfurt. Rethinking the Frankfurt School, a deceptively slim volume that manages to cover a lot of ground in a dozen densely packed essays edited by Jeffrey T. Nealon and Caren Irr, counters the conventional cultural studies wisdom regarding the Frankfurt School, debunking along the way not just the facile dismissal of some of the school's members for their "mandarin elitism," but also the notion that the scholars who arguably pioneered the critical study of mass culture have lost their relevance for cultural studies.The association of the Frankfurt School with a cranky and outdated variant of bourgeois proto-Marxism—what Lukacs once dismissed as self-indulgent despair cultivated in the comfort of "the Grand Hotel Abyss"—was at least in part a legacy of the rediscovered cultural and political optimism of the late 1960s. This optimism came to characterize those strands of cultural studies that countered the gloomy assessments of the Frankfurt School with the potential of what the collection's editors disparagingly describe as "subversive consumption." From the perspective of the new millennium it's no longer the Frankfurt scholars who look misguided. In a turning of the tables, the outdated figure of this volume is not Adorno, the pointy-headed pessimist, but rather those who helped dismiss him as such. In particular, Simon During, who edited the 1993 version of the cultural studies canon, The Cultural Studies Reader, comes in for a double dose of implicit criticism (thanks in part to what seems to be an editing oversight) for his critique of Horkheimer and Adorno's failure to take into account [End Page 92] the "opportunities for all kinds of individual collective creativity and decoding" provided by the culture industries (3, 62). If, as During suggested, the 1960s represented a time in which the mass media had become more variegated and presumably more flexible and porous than in the period treated by Horkheimer and Adorno, this collection suggests the renewed relevance of the Frankfurt School might in part be explained by the "unprecedented consolidation within the multinational 'infotainment' industry" during the 1990s (5). The triumphal resuscitation and consolidation of monopoly capitalism triggers, on this account, the rehabilitation of its most scathing critics.The more compelling argument advanced in this volume, however, is that the ostensibly outdated character of much of the work of the Frankfurt School was as much a result of superficial and dismissive readings as of changing historical conditions. As contributor Evan Watkins suggests in his discussion of Adorno, the dominant tendency in culture studies has been to contradict disparaging claims about mass culture (claims which earned Adorno and Horkheimer the sticky moniker of elitists) rather than to take seriously an approach that explored the intricate connections between mass culture and the social relations of production and consumption. Only in the abstract can the consumption of ostensibly counter-hegemonic texts be figured as subversive politics, especially during a time when "The Times They Are A-Changin' " can become a jingle for a bank commercial.Against the theoretical backdrop of the Frankfurt School, the very attempt to isolate culture as a sphere of resistance unto itself becomes a symptom of reification. As Imre Szeman puts it, perhaps the most important lesson of the Frankfurt School for cultural studies "can be summarized by a negative maxim: don't fetishize culture" (74... (shrink)

In this commentary, arguments are made for a dendritic code being preferable to a temporal synaptic code as a model of conscious experience. A temporal firing pattern is a product of an ongoing neural computation; hence, it is based on a neural algorithm and an algorithm may not provide the most suitable model for conscious experience. Reiteration of a temporal firing code as suggested in a preceding article (Helekar, 1999) does not necessarily improve the situation. The alternative model presented (...) here is that certain synaptic activity patterns, possibly those possessing universal features as suggested by Helekar, can become encoded in the dendritic structure. Following dendritic encoding, quantum phenomena in those specific dendrite sets could illuminate the static image of that encoded synaptic activity. It is the activation of the static image that would be equivalent to conscious experience; thus, conscious awareness would not be directly affiliated with synaptic activity. This dendrite encoding model may go farther than other models to explain the gestalt nature of consciousness, insofar as quantum entanglement could produce an interconnectedness between specific sets of dendrites-an interconnectedness that need not be based on neural computation or neural connections.

The basic risk for culture in conditions of globalization consists in full submission of its existence to economic (market) rules. The masscult deprived a variety - a product of such submission. But a source of creative development was and there is a cultural variety. Domination of a masscult leads to decrease in creative potential of the person and a society. Becoming of metaculture as culture of gift of a modern society represents alternative as to principles of a masscult, and (...) ideas of multiculturalism and tolerance. The principle of tolerance is a recognition of powerlessness to involve cultures in productive dialogue, de-facto it is recognition of the established cultural barriers. The culture of gift (metaculture) is based on following principles: 1) reflexivity, 2) ethicness, 3) positive role ofOtherness, 4) the sacrifice of an autonomy to (accept of gift), 5) new cultural-historical type of rationality is focused not on things, but on events, 6) more easy approach to products of cultural creativity and in this direction - alternative to deadlocks of protection to intellectual property (copyright). Development of metaculture corresponds to principles of a symbolical exchange and «copyleft». (shrink)

Dieses Open-Access-Buch gibt aktuelle interdisziplinäre Forschungseinblicke rund um das Fab City-Konzept. Ein Ansatz, der beschreibt, wie Produktions- und Konsumptionsweisen gestaltet werden können, sodass einerseits globale Kollaboration in und durch Communities von der Ideengenerierung bis zur Produktentwicklung physischer Güter mittels quelloffener Technologien (Open Source Software und Hardware) ermöglicht wird und andererseits die Produktion dieser Güter lokal und somit möglichst nahe am Ort des Bedarfs sowie dezentral im Sinne einer verteilten Produktion erfolgen kann, beispielsweise in Fab(rication) Labs. Ziel ist die Schaffung einer (...) möglichst nachhaltigen Produktion bzw. Wertschöpfung. Ökologisch nachhaltig, indem lange Transportwege vermieden und auf Grundlage von Kreislaufprinzipien lokale Stoffkreisläufe geschlossen werden. Ökonomisch nachhaltig, indem durch quelloffene Technologien Wettbewerbsbeschränkungen und durch föderierte Ansätze Abhängigkeiten vermieden werden. Sozial nachhaltig durch ein partizipatives Wertschöpfungssystem, in dem der Zugang zu Wissen und Knowhow sowie zu Produktionsmitteln unbeschränkt ist. Über den gesamten Produktentstehungsprozess und -lebenszyklus enthält das vorliegende, bilinguale Werk in deutscher und englischer Sprache Beiträge aus den Bereichen Citizen & Collaborative Innovation and Design, Circular Design & Economy, Open-Source-Software-Tools für die Entwicklung von Open Source Hardware, Digital Product Passport, föderierte (Open-Source-) Systeme, die Verbreitung von Open Source Hardware sowie technical literacy und economic governance. Prof. Neil Gershenfeld, Director of MIT's Center for Bits and Atoms, and Chairman of the board of The Fab Foundation: "For many years the growth of cities has been an inexorable trend, with cities acting as regional magnets and engines; the resources enabling a Fab City can also help expand opportunity beyond cities. There is now an opportunity and need for labs that can develop, deploy, and measure the frontiers of Fab City technologies. This book provides a much-needed snapshot of the current state of that challenge." Tomas Diez, Executive Director of the Fab City Foundation: "This book is an invitation for large-scale collaboration to build distributed system that can support the development of alternative modes of production, in line with the social and ecological needs of our time.".

This paper examines the problem of alternatives to the prison in order to problematize the prison as an institution, as a form of punishment and as a system for promoting respect for the law. It argues that the mechanisms that were central to the prison during the 19th century, such as the practice of penitence as a principle of rehabilitation, the family as agent of correction, or as agent of legality, and labour as a fundamental instrument for punishment, still operate (...) today, if in altered forms, in both the conventional and alternatives types of prison. The prison has been a factory for producing criminals; this production is not a mark of its failure but of its success. Prison manages control over illegalities by means of a whole set of apparatuses that manage their reorganization, redistributing them according to an economy of illegalisms. It may well be that changes in the economy and in the mechanisms for regulating populations mean that the carceral functions of the prison are today being disseminated at the level of the social body, so that they would now operate beyond the space of the prison through multiple instances of control, surveillance, normalization and re-socialization. The question of the prison cannot be resolved or even posed in terms of a simple penal theory. Neither can it be posed in tems of a psychology or sociology of crime. The question of the role and possible disappearance of the prison can only be posed in terms of an economy and a politics, that is, a political economy of illegalisms. (shrink)

Alternative splicing (AS) is a widespread mechanism with an important role in increasing transcriptome and proteome diversity by generating multiple different products from the same gene. Evolutionary studies of AS have focused primarily on the conservation of alternatively spliced sequences or of the AS pattern of those sequences itself. Less is known about the evolution of the regulation of AS, but several studies, working from different perspectives, have recently made significant progress. Here, we categorize the different levels of AS (...) evolution, and summarize the studies on evolution of AS regulation, which point to a high level of evolutionary conservation of the regulation of AS events conserved between related species. This suggests that the quantitative regulation of AS is an intrinsic part of AS function. We discuss the potential role of changes in developmental regulation of AS as an additional layer in complex gene regulatory networks and in the emergence of genetic novelties. (shrink)

Alternative food networks (AFN) are argued to provide platforms to re-socialize and re-spacealize food, establish and contribute to democratic participation in local food chains, and foster producer–consumer relations and trust. As one of the most recent examples of AFN, Participatory Guarantee Systems (PGS) have gained notable traction in attempting to redefine consumer-producer relations in the organic value chain. The participation of stakeholders, such as consumers, has been a key element theoretically differentiating PGS from other organic verification systems. While research (...) on farmer participation in PGS is attracting interest, consumer participation is still widely overlooked. Using a mixed methods approach, this paper describes five PGS markets in Mexico, Chile and Bolivia. A survey was conducted with consumers in the PGS markets to explore their awareness of the PGS, how consumers participate in the PGS, and their level of trust in the respective PGS and its certified products. Results showed a low level of awareness of PGS among market consumers, few participation possibilities, and minimal consumer participation overall. Nevertheless, trust in organic quality was generally high. Consumers primarily relied on the direct relationship with producers and the PGS market itself as sources of trust. These results provide novel insight into PGS consumer-market interactions, and contribute to discussions concerning social embeddedness, awareness and participation within AFN. (shrink)
