Large-scale land acquisitions (LaSLA), otherwise ‘land grabbing’ in Sub-Saharan Africa (SSA), raise difficult normative questions the current literature does not sufficiently explore. LaSLA is associated with development opportunities; however, it also threatens the well-being of local people because of displacement and dispossession. To investigate the processes and outcomes for LaSLA to be considered as ‘just and fair,’ we evaluate the impacts of a LaSLA project on local livelihoods in Tanzania. Specifically, we apply John Rawls’ Theory of (...) Justice to the project and compare the results with empirical insights gained from our fieldwork. We find that LaSLA has the potential to improve the living standards of local people, we cannot consider LaSLA as just and fair because it contradicts Rawls’s principles of justice and deteriorates the livelihoods of local people. Our findings suggest that it is critical to scrutinize LaSLA investments, involve local people in decision-making, and build the capacity of host governments to negotiate better LaSLA deals.

Large-scale land acquisition (LaSLA) in developing countries is discussed controversially in both the media as well as academia: Opponents point to negative social and environmental consequences. By contrast, proponents conceive of LaSLA as much needed investment into the formerly neglected agricultural sector. This contribution aims at analyzing LaSLA’s environmental dimension against the background of strong sustainability. To this end, I will first introduce sustainable development as a normative concept based on claims for intra- and intergenerational justice. (...) Subsequently, I will argue in favor of a conception of strong sustainability and employ this conception in developing guidelines for the sustainable handling of natural capital. By outlining the main drivers and consequences of LaSLA, the contribution hopes to demonstrate that proponents conceive of LaSLA as a potential solution to several sustainability problems, notably answering growing worldwide demand for agricultural commodities by increasing agricultural yields, substituting agrofuels for fossil fuels and providing acreage for offsetting carbon emissions. Against this background I argue that if LaSLA causes environmental externalities, it actually increases the problems it is supposed to resolve. Thereby, I develop sustainability criteria in regard to LaSLA’s environmental consequences. (shrink)

Commercial interest in land (large-scale land acquisition, LaSLA) in developing countries is a hot topic for debate and its potential consequences are contentious: proponents conceive of it as much needed investment into the formerly neglected agricultural sector while opponents point to severe social and environmental effects. This contribution discusses, if and how sustainability standards and codes of conduct can contribute towards governing LaSLA. Based on the WCED-definition we develop a conception of sustainability that allows framing (...) potential negative effects as issues of intra- and intergenerational justice. In a second step we specify these claims of justice, drawing on a human rights approach as well as three guidelines for sustainable development, namely, efficiency, consistency and resilience, to arrive at six guidelines for social and environmental sustainability criteria of LaSLA. We compare our suggestions with existing proposals for sustainability standards of LaSLA and with the certification schemes for sustainable production of bioenergy. From this we draw lessons for development and implementation of sustainability standards for LaSLA. (shrink)

Proponents of large-scale land acquisitions (LaSLA) argue that poor countries could benefit from foreign direct investment in land (World Bank 2011), while opponents argue that LaSLA is nothing more than neo-colonial theft of poor peasants’ livelihoods, i.e., land grabbing (Borras and Franco in Yale Hum Rights Dev L J, 13: 507–523, 2010a). To ensure responsible agricultural investments (RAI), a voluntary “code of conduct” for land acquisitions has been proposed by the World Bank (2011) and (...) the FAO (2012). A critical reaction to the “code of conduct” approach is the proposal for a set of minimum human rights principles, suggested by the UN Special Rapporteur on the Right to Food, De Schutter (2009). Even more critical of the “code of conduct” approach are Borras and Franco in Yale Hum Rights Dev L J, 13(2): 507–523, 2010a, who propose empowering small-scale farmers by giving them land sovereignty so that they are assured control over their land. This paper is a review of the governance and ethics issues connected to LaSLA. It has four main objectives: First, it offers a critical presentation of three major governance approaches to LaSLA: the “liberal code of conduct” (FAO and the World Bank), the ‘critical liberal human rights’ approach (De Schutter) and the ‘Marxist’ approach (Borras and Franco). Second, it discusses the notion of a human right to land, with reference to John Locke’s theory of appropriating land. Third, it discusses the issue of ensuring an inclusive process in LaSLA. Finally, an argument is made for instituting a (global) obligation to refrain from participating in or benefitting from institutional schemes that facilitate negative land grabbing (Pogge in Politics as usual: what lies behind the pro-poor rhetoric? Polity Press, Cambridge 2010). (shrink)

During the 2007–2008 global food crisis, the prices of primary foods, in particular, peaked. Subsequently, governments concerned about food security and investors keen to capitalize on profit-maximizing opportunities undertook large-scale land acquisitions (LASLA) in, predominantly, least developed countries (LDCs). Economically speaking, this market reaction is highly welcome, as it should (1) improve food security and lower prices through more efficient food production while (2) host countries benefit from development opportunities. However, our assessment of the debate on the (...) issues indicates critical voices in both the media and academic discourse. This article aims to provide a philosophical law and economics analysis. We draw on John Rawls’s Theory of Justice, focusing on Rawls’s background institutions for distributive justice (§43) to evaluate LASLA form an ethical angle. Approaching LASLA into Sub Saharan LDCs as a socio-economic reform redistributing land from the local population of LDCs to investors, we acknowledge that they bear a highly desirable potential. Often, though, they cannot be regarded as ethically correct in practice as the insignificant improvements for local populations and sometimes even human rights violations contradict Rawls’s principles of justice. Then investigating whether and how international law can help overcome the shortcomings, we conclude that even though respective mechanisms exist in the current state of international law, it is hardly possible that it will produce more just outcomes in the near future.

This article argues that the definition of land grabs in public debate is a politically contested process with profound normative consequences for policy recommendations regarding the future of the family farm model. To substantiate this argument, I first explore how different definitions of land grabbing bring into focus different kinds of actors and briefly survey the history of land grabbing in Canada. I then introduce the public debate about land grabbing in Québec and discuss its evolution (...) from its beginning in 2009 up until the provincial public inquiry on land grabs in March 2015. Here, I make critical observations regarding each participant’s position, showing how different definitions of land grabbing has significant implications for policy recommendation and the promotion of different agricultural business models. More specifically, I emphasize how these discussions crucially fail to consider indigenous people’s land rights and ignore the constraints imposed by the corporate food regime on family farms. I conclude by suggesting that the adoption of a food sovereignty approach to land governance helps redirect attention to these important issues and provide insight into imagining more sustainable alternative models of agriculture.

This paper distinguished different analytical approaches to the evaluation of the sustainability of large-scale land acquisitions—at both the conceptual and methodological levels. First, at the conceptual level, evaluation of the sustainability of land acquisitions depends on what definition of sustainability is adopted—strong or weak sustainability. Second, a lack of comparative empirical methods in many studies has limited the identification of causal factors affecting sustainability. An empirical investigation into the sustainability of land acquisitions in Tanzania that (...) employs these existing concepts in a methodologically rigorous manner offers an opportunity to more clearly addresses ethical questions surrounding international land acquisitions. My findings indicate that it should not be assumed that sustainability necessarily hinges on issues of strong sustainability, particularly that all village lands represent critical natural capital. As a result of its unique history of Ujamaa villagization, Tanzania villages often have ownership of significant tracts of unused land that mitigates the risk of violating conditions of strong sustainability. Issues of weak sustainability appear to be more important to villagers—particularly the degree of man-made capital benefits derived from projects. While compensation rates for lands acquired were low and the process lacked transparency, low compensation rates are not sufficient grounds for rejecting land acquisitions as unsustainable. When projects deliver significant man-made capital benefits, low compensation rates were not a politically salient issue amongst villagers. Finally, results suggest that some prioritization of man-made capital over biodiversity can be ethically defensible when the decision-making process goes through legitimate village government bodies and benefits reach poor villagers.

The recent global surge in large-scale foreign land acquisitions marks a radical transformation of the global economic and political landscape. Since land that attracts capital often becomes the site of expulsions and displacement, it also leads to new forms of migration. In this paper, I explore this connection from the perspective of a political philosopher. I argue that changes in global land governance unsettle the congruence of political community and bounded territory that we often take (...) for granted. As a case study, I discuss the European Union’s Renewable Energy Directive as a significant driver of foreign land acquisitions. Using its global power, the European Union (EU) is effectively governing land far outside of its international borders and with it the people who live on this land or are expelled from it. As a result, EU citizens ought to consider such people fellow members of their political community. This has implications for normative debates about immigration and, in particular, for arguments that appeal to collective self-determination to justify a right of political communities to exclude newcomers. The political community to which EU citizens belong reaches far beyond the EU’s official borders. (shrink)

The recent surge in land-based investments in the global South has been seen as both an opportunity for rural economic development and as a trend that poses significant social and environmental risks. This study sheds light on this debate through a look at the tobacco industry in Malawi. We employ a case study approach to investigate how rights, property, and authority associated with land and forest resources have shifted in the context of expanded investments in tobacco, and the (...) stakes for both local land users and citizens. Findings point to the need to broaden the metric of risks and trade-offs associated with large-scale land acquisitions, and to engage in a deeper reading of how these are borne out throughout history.

Large-scale transnational land acquisition of agricultural land in the global south by rich corporations or countries raises challenging normative questions. In this article, the author critically examines and advocates a human rights approach to these questions. Mutually reinforcing, policies, governance and practice promote equitable and secure land tenure that in turn, strengthens other human rights, such as to employment, livelihood and food. Human rights therefore provide standards for evaluating processes and outcomes of transnational (...) class='Hi'>land acquisitions and, thus, for determining whether they are ethically unacceptable land grabs. A variety of recent policy initiatives on the issue have evoked human rights, most centrally through the consultation and negotiation of the Voluntary Guidelines on the Responsible Governance of Tenure of Land, Fisheries and Forests concluded in 2012. However, a case of transnational land appropriation illustrates weak host and investor state enforcement of human rights, leaving the parties to in interaction with local groups in charge of protecting human rights. Generally, we have so far seen limited direct application of human rights by states in their governance of transnational land acquisition. Normative responses to transnational land acquisition—codes of conduct, principles of responsible agricultural investment or voluntary guidelines—do not in themselves secure necessary action and change. Applying human rights approaches one must therefore also analyze the material conditions, power relations and political processes that determine whether and how women and men can secure the human rights accountability of the corporations and governments that promote large-scale, transnational land acquisition in the global south.

The recent phenomenon of land grabbing—that is, the large-scale acquisition of private land rights by foreign investors—is an effect of increasing global demand for farmland, resources, and development opportunities. In 2008–2010 alone, land grabs covered approximately 56 million hectares of land, dispossessing and displacing inhabitants. This article proposes a philosophical framework for evaluating land grabbing as a practice of territorial alienation, whereby the private purchase of land can, under certain conditions, lead (...) to a de facto alienation of territorial sovereignty. If land grabs alienate territorial sovereignty, it follows that inhabitants can claim a violation of the people’s right to “permanent sovereignty over natural resources.” However, because sovereignty is entangled in the historical and contemporary causes of land dispossession, I cast doubt on this strategy. Territorially sovereign regimes often undermine democratic land governance by obstructing participation in activities such as zoning, land use, property regulation, and environmental stewardship. These activities, which I theorize as practices of “world-building,” are key to democracy because they give occupants a say in the shape of their common home. The perplexities of sovereignty in matters of land governance suggest that establishing democratic participation in rule over land requires fracturing sovereignty. (shrink)

This article examines land-use changes by large-scale plantations in Ethiopia and evaluates the impacts thereof on soil organic carbon, micronutrients and bulk density. Remote sensing analysis and field research activities were undertaken at four large-scale plantation projects in Benshanguel Gumuz, Gambella, and Oromia regional states. Results show that the projects largely involved the conversion of both closed and open to closed forests and grasslands, which in turn reduced soil carbon stock and micronutrient levels and increased (...) soil compaction. We argue that unless appropriate soil management activities and impact mitigation strategies are adopted by plantation proponents, these land-use changes will pose a serious threat to the long-term economic viability and sustainability of plantation agriculture in Ethiopia. This could undermine long-term ecosystem health and national food security. (shrink)

We present statistical analyses of the large‐scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small‐world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of connections follow power laws that indicate a scale‐free pattern of connectivity, with most nodes having relatively few connections joined together through a small number of hubs with many (...) connections. These regularities have also been found in certain other complex natural networks, such as the World Wide Web, but they are not consistent with many conventional models of semantic organization, based on inheritance hierarchies, arbitrarily structured networks, or high‐dimensional vector spaces. We propose that these structures reflect the mechanisms by which semantic networks grow. We describe a simple model for semantic growth, in which each new word or concept is connected to an existing network by differentiating the connectivity pattern of an existing node. This model generates appropriate small‐world statistics and power‐law connectivity distributions, and it also suggests one possible mechanistic basis for the effects of learning history variables (age of acquisition, usage frequency) on behavioral performance in semantic processing tasks.

This article examines the expansion of agrofuels in the Americas and the ecological impacts associated with the technologies used in the production of large-scale monocultures of corn and soybeans. In addition to deforestation and displacement of lands devoted to food crops due to expansion of agrofuels, the massive use of transgenic crops and agrochemical inputs, mainly fertilizers and herbicides used in the production of agrofuels, pose grave environmental problems.

Much of Edmonton’s municipal past lacked any overarching development plan. Once such absentee municipal planning gave way to more concrete forms of municipal planning in terms of shaping the urban environment, conflicting goals soon emerged. Between 1949 and the early 1980s a conflict in planning goals within both the Edmonton District Planning Commission and the City of Edmonton, at this time governed with a commission board became apparent. Often this conflict played out in Edmonton’s river valley with competing visions of (...) preservation and freeway construction. River valley neighborhoods were threatened with land acquisition policies that viewed the river valley as the sole domain of parkland. Concurrently, those neighborhoods and much of the river valley were also threatened by the Metropolitan Edmonton Transportation Study. Citizen engagement in an otherwise politically apathetic city led to its demise, although the threat of large-scale removal of river valley parks and homes throughout the city loomed for some time. The period between 1949 and 1983 represents a period in Edmonton’s history where environmental protection policy clashed with transportation policy that advocated for the wholesale destruction of the river valley and countless homes. It is this conflict that led to increased political awareness that directly contributed to the demise of the METS scheme and gave rise to renewed support for river valley protection while making rapid transit a possibility for Edmonton.

The Coal Seam Gas extraction industry is developing rapidly within the Surat Basin in southern Queensland, Australia, with licenses already approved for tenements covering more than 24,000 km2. Much of this land is used for a broad range of agricultural purposes and the need for coexistence between the farm and gas industries has been the source of much conflict. Whilst much research has been undertaken into the environmental and economic impacts of CSG, little research has looked into the issues (...) of coexistence between farmers and the CSG industry in the shared space that is a farm business, a home and a resource extraction network. We conducted three workshops with farmers from across a broad region undergoing CSG development to explore farmers’ perceptions of some of the issues arising from large scale land use change. Workshops explored the importance of place identity and landscape aesthetics for farmers, farmers’ acceptance and coping with change, and possible benefits from off-farm income. We found that farmers believed that place identity was not well understood by CSG staff from non-rural backgrounds and that farmers struggled to explain some concerns because of the different way they interpreted their landscape. Furthermore, high staff turnover, and the extensive use of contractors also impacted on communications. These factors were the cause of much frustration and farmers felt that this has led to severe impacts on mental health and wellbeing. Farmers felt that a change in culture within the CSG companies will be required if engagement with farmers is to improve and that efforts to employ local people in these communications was helping this. The workshops also identified a range of issues perceived by farmers arising from increased traffic volumes, impacts to mental health and wellbeing, place identity and loss of water resources for farmers. Finally, it was suggested that scientists and agricultural industry groups will need to work closely with farmers to develop understanding of these emerging issues and to develop solutions that are timely and relevant.

We describe a pattern acquisition algorithm that learns, in an unsupervised fashion, a streamlined representation of linguistic structures from a plain natural-language corpus. This paper addresses the issues of learning structured knowledge from a large-scale natural language data set, and of generalization to unseen text. The implemented algorithm represents sentences as paths on a graph whose vertices are words. Significant patterns, determined by recursive context-sensitive statistical inference, form new vertices. Linguistic constructions are represented by trees composed of (...) significant patterns and their associated equivalence classes. An input module allows the algorithm to be subjected to a standard test of English as a Second Language profi- ciency. The results are encouraging: the model attains a level of performance considered to be “intermediate” for 9th-grade students, despite having been trained on a corpus containing transcribed speech of parents directed to small children.

When large-scale common land is taken from villagers by investors with little compensation, their labour unneeded, villagers’ livelihoods tend to be largely destroyed. This implies a tendency to focus on what has been taken from villagers during the land-based change, which has valid and has far-reaching social relevance. But as the rise of the industrial tree plantation (ITP) sector in Guangxi shows, some villagers are capable of having their livelihoods maintained and even expanded when big investors (...) come and acquire massive amounts of land. This seems to be an anomaly at a first glance, considering what has been taken from villagers, but these unexpected and positive livelihood changes can be explained when one closely examines the dynamic of what is taken and what has been left to villagers. During this ITP boom, although large-scale collectively owned forestland is taken by investors and few work opportunities are created to incorporate those affected, villagers’ control over farmland plots and their access to off-farm work opportunities remain (including the land system and labour dynamics). This paper highlights the importance of analysing “taken-left” dynamics to more fully capture diverse livelihood changes. (shrink)

Though a recent phenomenon, land grabs have generated considerable debate that remains highly polarized. In this debate, one view presents land deals as a path to sustainable and transformative rural development through capital accumulation, infrastructural development, technology transfer, and job creation while the alternative view sees land grabs as a new wave of neo-colonization, exploitation, and domination. The underlying argument, at least theoretically, is that international land deals unlock the much needed capital to accelerate the achievement (...) of sustainable and transformative rural development in developing countries. It is against this backdrop that this paper examines the contribution of large scale land deals in Malawi to rural development by employing the political economy perspective using the Limphasa Sugar Corporation as a case study with particular focus on the nature and interest of the actors involved; the legal framework supporting large scale land deals; major individual and community benefits; and the extent to which these large land deals can indeed bring about sustainable and transformative rural development. The findings of this article demonstrate that large scale land deals present short term benefits to local communities such as capital for rural development; technology transfer and job creation in exchange for the priceless economic and social capital that local people depend upon; destruction of local social systems; deepening of local communities’ vulnerability to economic shocks; and the entrenchment of community dependence that may in the long run result in social and political unrest.

In rural Cambodia the rampant allocation of state land to political elites and foreign investors in the form of “Economic Land Concessions (ELCs)”—estimated to cover an area equivalent to more than 50 % of the country’s arable land—has been associated with encroachment on farmland, community forests and indigenous territories and has contributed to a rapid increase of rural landlessness. By contrast, less than 7,000 ha of land have been allotted to land-poor and landless farmers under (...) the pilot project for “Social Land Concessions (SLCs)” supported by various donor agencies. Drawing on fieldwork conducted in two research sites in Kratie Province, this article sheds light on the mechanisms and discourses surrounding the allocation of ELCs and SLCs. Our findings suggest that large-scale and non-transparent land leases in the form of ELCs are discursively justified as land policy measures supporting national development, creating employment opportunities in rural areas, and restoring “degraded” and “non-use” land, while SLCs are presented by the government and its international donors as a complementary policy to reduce landlessness, alleviate rural poverty, and ensure a more equitable land distribution. We argue that the SLC pilot project is a deliberate strategy deployed by the Cambodian ruling elite to instrumentalize international aid agencies in formalizing displacement and distributional injustices, in smoothing the adverse social impacts of their very own land policies and in minimizing resistance by dispossessed rural people.

Using connectionist modeling, we address fundamental questions concerning the acquisition process of musical tonal schema of listeners. Compared to models of previous studies, our connectionist model (Learning Network for Tonal Schema, LeNTS) was better equipped to fulfill three basic requirements. Specifically, LeNTS was equipped with a learning mechanism, bound by culture-general properties, and trained by sufficient melody materials. When exposed to Western music, LeNTS acquired musical ‘scale’ sensitivity early and ‘harmony’ sensitivity later. The order of acquisition of (...) scale and harmony sensitivities shown by LeNTS was consistent with the culture-specific acquisition order shown by musically westernized children. The implications of these results for the acquisition process of a tonal schema of listeners are as follows: (a) the acquisition process may entail small and incremental changes, rather than large and stage-like changes, in corresponding neural circuits; (b) the speed of schema acquisition may mainly depend on musical experiences rather than maturation; and (c) the learning principles of schema acquisition may be culturally invariant while the acquired tonal schemas are varied with exposed culture-specific music.

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

Traditional methods for deriving property-based representations of concepts from text have focused on either extracting only a subset of possible relation types, such as hyponymy/hypernymy (e.g., car is-a vehicle) or meronymy/metonymy (e.g., car has wheels), or unspecified relations (e.g., car—petrol). We propose a system for the challenging task of automatic, large-scale acquisition of unconstrained, human-like property norms from large text corpora, and discuss the theoretical implications of such a system. We employ syntactic, semantic, and encyclopedic information (...) to guide our extraction, yielding concept-relation-feature triples (e.g., car be fast, car require petrol, car cause pollution), which approximate property-based conceptual representations. Our novel method extracts candidate triples from parsed corpora (Wikipedia and the British National Corpus) using syntactically and grammatically motivated rules, then reweights triples with a linear combination of their frequency and four statistical metrics. We assess our system output in three ways: lexical comparison with norms derived from human-generated property norm data, direct evaluation by four human judges, and a semantic distance comparison with both WordNet similarity data and human-judged concept similarity ratings. Our system offers a viable and performant method of plausible triple extraction: Our lexical comparison shows comparable performance to the current state-of-the-art, while subsequent evaluations exhibit the human-like character of our generated properties.

In this paper I propose a series of hypotheses for further study that are related to potential negative impacts of non-traditional export agriculture (NTEA) on peasantfarmers in Central America. International lenders and donor agencies are promoting this diversification of agricultural exports as part of structural adjustment programs in the region, in order to increase foreign exchange earnings and raise the incomes of the rural poor.There is growing evidence, however, that the impact on the rural poor may not be favorable. I (...) argue that because NTEA can introduce powerful economies of scale, it is likely to accelerate social differentiation in the countryside and expel large numbers of peasant farmers from their lands. In this sense NTEA may be similar to previous export ‘booms,’ leading to rapid intensification of social instability and conflict in an already troubled region. This raises the serious question of the long term sustainability of this development strategy.There is a shortage of published studies that directly address these issues, making further work essential for the adequate review of NTEA policies. I formulate six testable hypotheses based on the economies of scale associated with NTEA. Each is related to a resource essential for successful agricultural production: land; credit; prices, costs, and subsidies; technology; technical assistance; and markets. I suggest that as NTEA grows, small farmer access to each is reduced, eventually making peasant production for domestic consumption an unviable alternative, while those who venture into NTEA encounter unacceptable levels of risk.

Various aspects of semantic features drive early vocabulary development, but less is known about how the global and local structure of the overall semantic feature space influences language acquisition. A feature network of English words was constructed from a large database of adult feature production norms such that edges in the network represented feature distances between words (i.e., Manhattan distances of probability distributions of features elicited for each pair of words). A word's global feature distinctiveness is measured with (...) respect to all other words in the network and a word's local feature distinctiveness is measured relative to words in sub‐networks derived from clustering analyses. This paper investigates how feature distinctiveness of individual words at local and global scales of the network influences language acquisition. Regression analyses indicate that global feature distinctiveness was associated with earlier age of acquisition ratings, and was a stronger predictor of age of acquisition than local feature distinctiveness. These results suggest that the global structure of the semantic feature network could play an important role in language acquisition, whereby globally distinctive concepts help to structure vocabulary development over the lifespan.

Gregory Conniff's large-scale black and white pastoral images evoke the sensuality of nineteenth century photographic materials. In his affectionate and intelligent work, there is a visible connection to the history of landscape art, reaching back as far as Claude Lorrain and seventeenth-century Dutch drawing. Conniff is also a leading practitioner of a new pastoralism that is casting a contemporary eye on the current state of America's open land. Postmodern in the best sense, Conniff's pictures address the timeless (...) human need to see beauty in the world that shapes our lives. A resident of Wisconsin for more than thirty years, Conniff has focused much of his artistic energy on the rural Midwest, exploring the interdependent relationship between land and people. For the past fifteen years, Conniff has also been making pictures of rural Mississippi, again focusing on elements of the landscape that resonate with a universal sense of aesthetic familiarity. As he explains, "I am interested in work that defines and protects the vanishing, commonplace beauties that let us know we're home.". (shrink)

This paper examines the intersection of environmental history and the history of science, specifically the impact of forestry science and fire management on land use and community dynamics in rural Portuguese mountains. It further traces the evolution of fire management from an ancestral rural practice to a scientific concern and the subsequent integration of vernacular knowledge with scientific methods. In the early twentieth century, fire was a common tool in rural Portugal for land clearance, pasture management, and soil (...) enrichment. Rooted in local knowledge, these practices were increasingly challenged by the rise of scientific forestry, which viewed fire primarily as a threat to be controlled. By the mid-twentieth century, Portuguese forestry policies had undergone a significant shift toward aggressive fire suppression and large-scale afforestation, reflecting a broader trend of prioritizing timber production and forest protection. Notable shifts occurred in the 1970s, marked, among other factors, by the increase in rural fires, a new socioecological vision for the forest and the introduction of prescribed fire techniques influenced by international models. The paper argues that the establishment of scientific fire management practices represents a merging of expert knowledge with local experience. This move represents a shift from exclusionary policies toward a more nuanced understanding of fire’s role in landscape management. An examination of these historical developments demonstrates the intricate interrelationship between science, the environment, policy, and local practices, illustrating the way knowledge systems both shape and are shaped by environmental governance.

Prediction-based accounts of language acquisition have the potential to explain several different effects in child language acquisition and adult language processing. However, evidence regarding the developmental predictions of such accounts is mixed. Here, we consider several predictions of these accounts in two large-scale developmental studies of syntactic priming of the English dative alternation. Study 1 was a cross-sectional study (N = 140) of children aged 3−9 years, in which we found strong evidence of abstract priming and (...) the lexical boost, but little evidence that either effect was moderated by age. We found weak evidence for a prime surprisal effect; however, exploratory analyses revealed a protracted developmental trajectory for verb-structure biases, providing an explanation as for why prime surprisal effects are more elusive in developmental populations. In a longitudinal study (N = 102) of children in tightly controlled age bands at 42, 48, and 54 months, we found priming effects emerged on trials with verb overlap early but did not observe clear evidence of priming on trials without verb overlap until 54 months. There was no evidence of a prime surprisal effect at any time point and none of the effects were moderated by age. The results relating to the emergence of the abstract priming and lexical boost effects are consistent with prediction-based models, while the absence of age-related effects appears to reflect the structure-specific challenges the dative presents to English-acquiring children. Overall, our complex pattern of findings demonstrates the value of developmental data sets in testing psycholinguistic theory. (shrink)

Jared Diamond and other leading scholars have argued that the domestication of animals for food, labor, and tools of war has advanced the development of human society. But by comparing practices of animal exploitation for food and resources in different societies over time, David A. Nibert reaches a strikingly different conclusion. He finds in the domestication of animals, which he renames "domesecration," a perversion of human ethics, the development of large-scale acts of violence, disastrous patterns of destruction, and (...) growth-curbing epidemics of infectious disease. Nibert centers his study on nomadic pastoralism and the development of commercial ranching, a practice that has been largely controlled by elite groups and expanded with the rise of capitalism. Beginning with the pastoral societies of the Eurasian steppe and continuing through to the exportation of Western, meat-centered eating habits throughout today's world, Nibert connects the domesecration of animals to violence, invasion, extermination, displacement, enslavement, repression, pandemic chronic disease, and hunger. In his view, conquest and subjugation were the results of the need to appropriate land and water to maintain large groups of animals, and the gross amassing of military power has its roots in the economic benefits of the exploitation, exchange, and sale of animals. Deadly zoonotic diseases, Nibert shows, have accompanied violent developments throughout history, laying waste to whole cities, societies, and civilizations. His most powerful insight situates the domesecration of animals as a precondition for the oppression of human populations, particularly indigenous peoples, an injustice impossible to rectify while the material interests of the elite are inextricably linked to the exploitation of animals. Nibert links domesecration to some of the most critical issues facing the world today, including the depletion of fresh water, topsoil, and oil reserves; global warming; and world hunger, and he reviews the U.S. government's military response to the inevitable crises of an overheated, hungry, resource-depleted world. Most animal-advocacy campaigns reinforce current oppressive practices, Nibert argues. Instead, he suggests reforms that challenge the legitimacy of both domesecration and capitalism. (shrink)

"Permanent Things reminds us that some of the century's most imaginative minds - G. K. Chesterton, T. S. Eliot, C. S. Lewis, Dorothy Sayers, and Evelyn Waugh - were profoundly at odds with the secularist spirit of the age, seeing progressive enlightenment as ushering in, not a millennium of perfect freedom, but a Waste Land whose inhabitants - Waugh's "vile bodies," Eliot's "hollow men," Lewis's "men without chests" - can find refuge from their boredom and anomie only in the (...) ceaseless acquisition of things or in the consoling illusions of pseudo religions - "distracted from distraction by distraction," as Eliot memorably put it." "How does one explain the desolation of a world which, though richly endowed with material comforts, is mentally and spiritually impoverished?

Modern man's poverty of spirit, visible alike in so much of his art and architecture, his literature and philosophy and political science, reflects his loss of any good reasons for living - his loss of the Permanent Things." "The Christian writers whose work is eloquently interpreted in this book repay our attention for at least two reasons. First is their ability to sharpen our awareness of what, by any previous civilized standards, must be called the abnormal condition of modern man. For all the writers treated in this book, it was never enough to simply capture the spiritual aridity of modern life. It was also necessary to speak of a moral order that may yet be restored by the expressive power and beauty of the written word."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Engaging in unethical consumption behaviors is an acute societal problem that can have severe consequences for adolescents, and businesses in particular have been accused of making such consumption particularly appealing and accessible. However, the causes of unethical behaviors are not well understood and research on the causes has been mixed. In this research, we investigate the effects of coping strategies for loneliness on adolescents’ adoption of unethical behaviors, a topic that business ethics research has not explored. In a large- (...) class='Hi'>scale study of adolescents, we show that whether loneliness leads to the adoption of unethical behaviors depends on the strategies adolescents use to cope with their loneliness: active coping strategies are associated with fewer unethical behaviors, whereas passive coping strategies are associated with more unethical behaviors. In addition, we show that active and passive coping strategies can be executed through consumption practices. We show that the relation between active coping and fewer unethical behaviors is mediated by sharing of possessions, whereas the relation between passive coping strategies and more unethical behaviors is mediated by product acquisition. Finally, we also show that these mediated relations differ as a function of age cohort. The indirect effect of active coping on fewer unethical behaviors via sharing holds only for middle school adolescents, whereas the indirect effect of passive coping on more unethical behaviors via product acquisition holds only for high school adolescents. We shed new light on both the bright and dark sides of materialism and unethical behaviors and provide practical implications for research on loneliness, business ethics, and unethical behaviors.

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well-known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for language learning. Here, we investigate the relationship between semantic distance and phonological distance in the large-scale structure of the lexicon. We show evidence in 100 (...) languages from a diverse array of language families that more semantically similar word pairs are also more phonologically similar. This suggests that there is an important statistical trend for lexicons to have semantically similar words be phonologically similar as well, possibly for functional reasons associated with language learning.

The position advanced in this paper is that the bedrock of emotional feelings is contained within the evolved emotional action apparatus of mammalian brains. This dual-aspect monism approach to brain–mind functions, which asserts that emotional feelings may reflect the neurodynamics of brain systems that generate instinctual emotional behaviors, saves us from various conceptual conundrums. In coarse form, primary process affective consciousness seems to be fundamentally an unconditional “gift of nature” rather than an acquired skill, even though those systems facilitate skill (...) acquisition via various felt reinforcements. Affective consciousness, being a comparatively intrinsic function of the brain, shared homologously by all mammalian species, should be the easiest variant of consciousness to study in animals. This is not to deny that some secondary processes cannot be evaluated in animals with sufficiently clever behavioral learning procedures, as with place-preference procedures and the analysis of changes in learned behaviors after one has induced re-valuation of incentives. Rather, the claim is that a direct neuroscientific study of primary process emotional/affective states is best achieved through the study of the intrinsic , albeit experientially refined, emotional action tendencies of other animals. In this view, core emotional feelings may reflect the neurodynamic attractor landscapes of a variety of extended trans-diencephalic, limbic emotional action systems—including SEEKING, FEAR, RAGE, LUST, CARE, PANIC, and PLAY. Through a study of these brain systems, the neural infrastructure of human and animal affective consciousness may be revealed. Emotional feelings are instantiated in large-scale neurodynamics that can be most effectively monitored via the ethological analysis of emotional action tendencies and the accompanying brain neurochemical/electrical changes. The intrinsic coherence of such emotional responses is demonstrated by the fact that they can be provoked by electrical and chemical stimulation of specific brain zones—effects that are affectively laden. For substantive progress in this emerging research arena, animal brain researchers need to discuss affective brain functions more openly. Secondary awareness processes, because of their more conditional, contextually situated nature, are more difficult to understand in any neuroscientific detail. In other words, the information-processing brain functions, critical for cognitive consciousness, are harder to study in other animals than the more homologous emotional/motivational affective state functions of the brain.

Fiona Cowie’s What’s Within consists of three parts. In the first, she examines the early modern rationalist-empiricist debate over nativism, isolating what she considers the two substantive “strands” that truly separated them: whether there exist domain-specific learning mechanisms, and whether concept acquisition is amenable to naturalistic explanation. She then turns, in the book’s succeeding parts, to where things stand today with these issues. The second part argues that Jerry Fodor’s view of concepts is continuous with traditional nativism in that (...) it precludes a naturalistic story of concept acquisition. Cowie objects, however, to Fodor’s path to this conclusion and thus sees no reason to endorse it. The third part assesses Chomskyan nativism as a contemporary instance of positing domain-specific learning mechanisms. Though she is highly critical of how “poverty of the stimulus” arguments and the like have been used to lend credence to stronger conclusions, she holds that such arguments do indeed support the nativist’s domain-specificity claim. Cowie’s reconsideration of nativism thus limits itself to concepts and language. The terrain she does cover, however, is vast; and Cowie’s illuminating discussions will stimulate anyone interested in the area. As I focus on a few large-scale qualms in what follows, let me mention in particular that much of what is of interest in Cowie’s book is to be found in her detailed consideration of specific arguments.

Pork producers in Western Europe moreand more encounter a variety of societalconcerns about pork and pork production. Sofar, however, producers predominantly focusedon low consumer prices, therewith addressingjust one concern. This resulted in an intensiveand large-scale production system, decreasinglyrelated to the area of farm land, andaccompanied with increasing concerns aboutsafety and healthiness of pork, animal welfare,environmental pollution, and others.An overview was given of possible concernsabout West-European pork production with theconsumers, citizens, and producers, and thoseconcerns are traced back to (...) the pork productionsystem. The various kinds and qualities ofinformation about the pork production system onwhich possible concerns are based have beenworked out extensively in this paper. Knowledgeabout the aspects of pork production that cangive rise to concerns can be used in two ways.First, the communication about those aspectstowards consumers and citizens can be adjustedor extended to give them better possibilitiesto make food choices or to develop their ownopinions about pork production. Second,producers could change the pork productionsystem such that it better satisfies consumersand citizens. Such adaptations are wellpossible, as three pork quality schemes, whichhave been evaluated, illustrate. However, mostof these adaptations can only be carried out atthe cost of the present low consumer prices andwill not occur spontaneously on a large scale.Therefore, accounting for the type andrelevance of the concerns, legislation isnecessary to address societal concerns in abalanced way such that pork production systemsbecome acceptable for the majority of oursociety.

Biofuels development has assumed an important role in integrating Indigenous peoples and other marginalized populations in the production of biofuels for global consumption. By combining the theories of commoditization and the environmental sociology of networks and flows, the author analyzed emerging trends and possible changes in institutions and behaviors brought about by the introduction of biofuels as a development option on ancestral lands. Using the Indonesian oil palm and the Philippine Jatropha experiences, the author argues that although there are efforts (...) to integrate smallholder systems to the global integrated biofuels network, the effects of commoditization continue to undermine the more sustainable, less commoditized agricultural practices of Indigenous peoples. Indigenous peoples and their traditional agricultural practices are at risk of being either phased out from or eventually transformed by the global integrated biofuels network to accommodate large-scale, consolidated biofuel plantation systems. However, there are also indications that persistent criticisms of and enduring reforms in the global integrated biofuels network challenge the future of highly commoditized biofuels. This suggests that the coevolutionary trajectory of both highly commoditized biofuels and noncommoditized Indigenous agricultural practices remains uncertain. (shrink)

Whatfactors determine the nature and pace of technological development? The literature on social construction of technology and actor-network theory suggests that assembling "coalitions" of support and conveying a certain "rhetoric" of technology are important to moving technology forward They are especially crucial strategies for advocates of large-scale, government-supported technologies. These strategies are illuminated by cases of U.S. space satellite development: meteorological satellites, land satellites, and the Earth Observation System.

SummarySir William Willcocks (1852–1933) was a prominent British irrigation engineer who served in various British colonies. Best known as the chief designer of the Old Aswan Dam, Willcocks was born and trained in India, achieved prominence with his contribution to the development of centralized and perennial irrigation in Egypt, and was hired at the end of his career by the Ottomans to restore the ancient irrigation works of Mesopotamia (which was then on the verge of being acquired by the British). (...) In this article, I follow Willcocks' voyages across the British Empire and show how hydraulic science moved from one colonial centre to another, and how this movement contributed to the construction and maintenance of colonialism on the ground. Often sent to newly acquired territories with ambitious projects to redesign the landscapes of property and agriculture, Willcocks and other engineers who gained their expertise in the colonies relied on lessons from their day-to-day struggle with the land and other social actors' competing agendas to develop the daily techniques that helped establish colonial rule. As the reception of Willcocks' work in London illustrates, it was in the metropole that engineers' practices were translated into a colonial symbolism that had large-scale technical systems as the right tools for the job of subordinating unruly waters and Nature writ large.

The triumvirate of HIV/AIDS, tuberculosis, and malaria have dominated our public health focus in the developing world. Having claimed millions of lives, these infectious diseases have prompted a large-scale response. Concomitant with these efforts has been a burgeoning bioethics literature examining global health and distributive justice. A scholarly waste-land only a decade ago, there is now a growing and rich literature that aims to unpack our moral obligations when it comes to diseases that affect the majority of (...) the world (many living in absolute poverty). Now, added to the persistent challenges posed by infectious diseases is the growing burden of diseases such as cancer, which disproportionately affect .. (shrink)

This paper focuses on smallholder agriculture and livelihoods in north-central Tanzania. It traces changes in agricultural production and asset ownership in one community over a 28 year period. Over this period, national development policies and agriculture programs have moved from socialism to neo-liberal approaches. Using a combination of qualitative and quantitative methods, we explore how farmers have responded to these shifts in the wider political-economic context and how these responses have shaped their livelihoods and ideas about farming and wealth. This (...) case study clearly debunks the idea that rural farmers are slow to respond to “modern” farming methods or that smallholder farming is stagnant and cannot reduce poverty. While changes overall are very positive in this rural community, challenges remain as land sizes are small and markets often unreliable. This research cautions against a shift in emphasis to large-scale farming as a strategy for national development. It suggests instead that increased investment in supporting smallholder farming is critical for addressing poverty and rural well-being. (shrink)

Disputes over territory are among the most contentious in human affairs. Throughout the world, societies view control over land and resources as necessary to ensure their survival and to further their particular life-style, and the very passion with which claims over a region are asserted and defended suggests that difficult normative issues lurk nearby. Questions about rights to territory vary. It is one thing to ask who owns a particular parcel of land, another who has the right to (...) reside within its boundaries and yet another to determine which individuals or groups have political rights of citizenship, sovereignty, and self-determination within it. It must also be asked how these rights—if ‘rights’ is the correct term—are acquired. When attention turns to the territorial rights of communities, national groups or states, sovereignty is the principal concern. Within international law, de facto power over a territory, say, of occupying forces or trustees, is insufficient to possess or acquire sovereignty (Brownlie, 1990, p. 111). The central conceptions underlying modern democratic thought are that sovereignty over a politically demarcated territory is vested in the resident population, and that governmental authority is derived from the consent of that population. It is simple enough to identify the latter with the citizenry of a state, but demographic and political flux makes this a loose criterion. States come and go, and sometimes a territory is stateless. Also, large-scale demographic shifts during upheavals and peacetime immigrations change the assessments of who belongs where. Does everyone residing in a place at a particular time have a right to share in its governance then? What about illegal immigrants? Presumably, sovereignty rests with the established population or..

It is of scientific interest to consider the monastic and monastic vision of church-religious, socio-political, ethno-religious problems of the pre-war era in Ukrainian lands. Interest is dictated by the following factors and reasons. First, monastic centers from the time of Kievan Rus remained one of the most stable in the society and in their mass created a fairly representative network of peculiar indicators of the spiritual state of the Russian community in the regions. Secondly, through these spiritual centers there was (...) a large-scale reproduction in the generations of the whole world-view complex, which included not only church-religious, but also ideological, socio-political orientations, moral and cultural values, ethno-national traditions, etc. Third, it was from monasticism that the higher clergy formed, which then determined the position and course of the church as a whole. Fourth, the monasteries, in the face of socio-political transience and uncertainty, actually became the gatherers, producers and guardians of the spiritual achievements of the Russian community.

The processes underwriting the acquisition of culture remain unclear. How are shared habits, norms, and expectations learned and maintained with precision and reliability across large-scale sociocultural ensembles? Is there a unifying account of the mechanisms involved in the acquisition of culture? Notions such as “shared expectations,” the “selective patterning of attention and behaviour,” “cultural evolution,” “cultural inheritance,” and “implicit learning” are the main candidates to underpin a unifying account of cognition and the acquisition of culture; (...) however, their interactions require greater specification and clarification. In this article, we integrate these candidates using the variational (free-energy) approach to human cognition and culture in theoretical neuroscience. We describe the construction by humans of social niches that afford epistemic resources called cultural affordances. We argue that human agents learn the shared habits, norms, and expectations of their culture through immersive participation in patterned cultural practices that selectively pattern attention and behaviour. We call this process “thinking through other minds” (TTOM) – in effect, the process of inferring other agents’ expectations about the world and how to behave in social context. We argue that for humans, information from and about other people's expectations constitutes the primary domain of statistical regularities that humans leverage to predict and organize behaviour. The integrative model we offer has implications that can advance theories of cognition, enculturation, adaptation, and psychopathology. Crucially, this formal (variational) treatment seeks to resolve key debates in current cognitive science, such as the distinction between internalist and externalist accounts of theory of mind abilities and the more fundamental distinction between dynamical and representational accounts of enactivism.

The landscape of the Sundarbans today is a product of two countervailing forces: conversion of wetland forests to cropland vs. sequestration of the forests in reserves to be managed for long-term sustained yield of wood products. For two centures, land-hungry peasants strove to transform the native tidal forest vegetation into an agroecosystem dominated by paddy rice and fish culture. During the colonial period, their reclamation efforts were encouraged by landlords and speculators, who were themselves encouraged by increasingly favorable state (...) policies (land grants, tax incentives, cadastral surveys, and eventually colonization projects and subsidized irrigation) designed by revenue officials to maximize the rate of transformation of wetland forest to taxable agricultural land.In the late nineteenth century, as the rate of agricultural conversion increased, the colonial Forest Department succcessfully sought to preserve large areas of the remaining Sundarbans tidal forest by giving them legal status as Reserved or Protected Forests. These forests were intensively managed to provide a sustainable supply of timber and firewood for the increasing population of southern Bengal. Institutionalization of conflicting policies by the Revenue and Forest Departments reflected the escalating needs for both food and forest products as the colony grew. Today, supplies of some economically valuable trees have been depleted, and some mammals are locally extinct (although the Bengal tiger remains), but government policy in both Bangladesh and India now favors use of the Sundarbans as forest rather than its transformation to agricultural land. Further expansion of cropland to meet the grain demands of the burgeoning Bengali population in both nations has largely taken place outside the boundaries of the Sundarbans. Overexploitation of these forests for wood products remains a possibility, but large-scale clearing for rice paddies is unlikely under present policies. (shrink)

Many of the items that humans consume are produced in ways that involve serious harms to persons. Familiar examples include the harms involved in the extraction and trade of conflict minerals (e.g. coltan, diamonds), the acquisition and import of non- fair trade produce (e.g. coffee, chocolate, bananas, rice), and the manufacture of goods in sweatshops (e.g. clothing, sporting equipment). In addition, consumption of certain goods (significantly fossil fuels and the products of the agricultural industry) involves harm to the environment, (...) to future persons, and to current persons in low-lying and developing countries, by way of their impacts on climate change. When it comes to such large-scale harms, it's easy for the individual to feel helpless. Even if she sincerely wishes things were otherwise, she may wonder what she could possibly do to make them so. In this paper I briefly explore several promising avenues for generating duties in individuals to consume ethically, and develop one in particular: that an individual ought to signal her commitments to others, as a first step in collectivizing to act against unjust global labour practices.

The article attempts to comprehend the phenomenon of an event in the religious dimension. An event is considered as a phenomenon characterized by a singularity, that is, an individual character of expression, belongs to the sphere of non everyday life, does not coincide with the usual framework of understanding of the world and does not correspond to empirical factual. The need for a more active philosophical and religious discourse of the correlation between everyday and non everyday life in the realm (...) of religion led to the necessity of address to this problem. Thus, the purpose of the article is to find out the ontological status of the event, the religious context of which manifests itself as an opposition to everyday life and leads to a transformation of the established way of life of the believer. Everyday being is characterized by features of sacredness, demonstrates the attraction to the transcendent. For this reason, the obvious and justified is the combination of the phenomena of everyday empirical world with the values ​​of another dimension of being. The presence of non everyday in everyday life is evidenced, in particular, by elements of cult practice, since they are an expression of sacral time and space, as well as a way of incarnation of eternal values. The sphere of non everyday life includes the relationship between human and God described in the Gospels, prophecies, revelation, and vision as non everyday manifestations of religious experience. Event is the opposition of the world of phenomena to beyond the exquisite world of being, the transformation, which leads to the emergence of new orders and structures. Implementation of the event contradicts the previous ideas, therefore meeting the event with standard reality is accompanied by a transformation of everyday life. Establishing the rootedness of an event into being or its transcendental origin allows us to determine the causes of an event. In a secularized world, human, for the most part, demonstrates his willingness to recognize as significant events, including those in the universe, which correspond to scientific knowledge. This happens even when the fact of the event calls into question the fundamental postulates of science. Given this discovery in science, situations in politics, art, personal life are perceived as large-scale events. Moreover, the moment of meeting with the event can be described, for example, with a poetic language that expresses certain symbols of human existence and appears as a means of objectivizing the event as an unexpected innovation. Instead, the believer perceives events of a supernatural nature as an interference of the otherworldly reality in the usual way of life. Thus, the reception of religious experience is accompanied by the transformation of the individual's everyday life. The basis of the mystical experience of the religious tradition is the experience of meeting with the Divine, which results in a change in the believer's self-consciousness, transformation of its values, senses and meanings. That is, the awareness of an event that does not belong to an established order implies the prospect of new reality emersion, which contradicts previous notions. One of the forms of gaining religious experience is the process of conversion, which results in the transformation of the ideological orientation of a person, which enables the knowledge of their own hidden depths of consciousness. Conversion, the acquisition of grace and faith express the sudden or gradual process by which the individual achieves internal harmony, awareness of his righteousness, a sense of happiness, finds support in believing in the reality of what he has discovered in religious experiences.

If the cortex is an associative memory, strongly connected cell assemblies will form when neurons in different cortical areas are frequently active at the same time. The cortical distributions of these assemblies must be a consequence of where in the cortex correlated neuronal activity occurred during learning. An assembly can be considered a functional unit exhibiting activity states such as full activation (“ignition”) after appropriate sensory stimulation (possibly related to perception) and continuous reverberation of excitation within the assembly (a putative (...) memory process). This has implications for cortical topographies and activity dynamics of cell assemblies forming during language acquisition, in particular for those representing words. Cortical topographies of assemblies should be related to aspects of the meaning of the words they represent, and physiological signs of cell assembly ignition should be followed by possible indicators of reverberation. The following postulates are discussed in detail: (1) assemblies representing phonological word forms are strongly lateralized and distributed over perisylvian cortices; (2) assemblies representing highly abstract words such as grammatical function words are also strongly lateralized and restricted to these perisylvian regions; (3) assemblies representing concrete content words include additional neurons in both hemispheres; (4) assemblies representing words referring to visual stimuli include neurons in visual cortices; and (5) assemblies representing words referring to actions include neurons in motor cortices. Two main sources of evidence are used to evaluate these proposals: (a) imaging studies focusing on localizing word processing in the brain, based on stimulus-triggered event-related potentials (ERPs), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI), and (b) studies of the temporal dynamics of fast activity changes in the brain, as revealed by high-frequency responses recorded in the electroencephalogram (EEG) and magnetoencephalogram (MEG). These data provide evidence for processing differences between words and matched meaningless pseudowords, and between word classes, such as concrete content and abstract function words, and words evoking visual or motor associations. There is evidence for early word class-specific spreading of neuronal activity and for equally specific high-frequency responses occurring later. These results support a neurobiological model of language in the Hebbian tradition. Competing large-scale neuronal theories of language are discussed in light of the data summarized. Neurobiological perspectives on the problem of serial order of words in syntactic strings are considered in closing. Key Words: associative learning; cell assembly; cognition; cortex; ERP; EEG; fMRI; language; lexicon; MEG; PET; word category. (shrink)

As of September 2005, the co-founders of Waste Concern, an organisation dedicated to improving waste recycling in Bangladesh, are considering making a change to their model in order to get approval from the municipal government for a large-scale composting site. Since its inception in 1995, Waste Concern has followed a decentralised composting model whereby each composting site is a small-scale operation processing 3 tons of organic waste per day. In this model, they have relied on land (...) and waste supply from the Dhaka City Council (DCC) municipal government. Now, they are working with Dutch-based World Wide Recycling BV (WWR) to set up a 700-ton per day composting plant, which will enable them to earn tradable certificates for US$11 per ton of reduced methane gas, making it the first in the world to garner credits through composting waste under the United Nations Clean Development Mechanism (CDM). To launch the composting site, they face the hurdle of getting DCC’s approval. They have three alternatives: (1) follow through with the original plan whereby the municipality would supply both the land and waste, which entails waiting for DCC’s approval; (2) purchase the land for the composting site and rely on the municipality for a waste supply; or, (3) purchase the land and take on the responsibility of waste collection themselves. In their considerations, they need to weigh the financial and social aspects and determine an appropriate structure for their organisation. (shrink)
