There is growing interest in the role of new urban agriculture models to increase local food production capacity in cities of the Global North. Urban rooftop greenhouses and hydroponics are examples of such models receiving increasing attention as a technological approach to year-round local food production in cities. Yet, little research has addressed the unintended consequences of new modes of urban farming and food distribution, such as increased competition with existing peri-urban and rural farmers. We examine how small-scale farmers perceive (...) and have responded to a recently established rooftop greenhouse and online marketplace enterprise in Montréal, Canada. Drawing on interviews with key informants and small-scale farmers, we find that peri-urban and rural producers have been affected in three key ways that represent tensions, adaptations, and synergies arising from this new urban agriculture and food distribution enterprise. First, many farmers are concerned about increased competition and value conflation with the ideals of community supported agriculture and organic farming. Second, some farmers have adapted by developing novel marketing strategies and working with local bridge organizations to collectively market their produce to urban consumers. Third, a few farmers have decided to wholesale their produce to this new enterprise, allowing them to specialize production and avoid marketing their produce directly to urban consumers. Our study suggests that the emergence of a new form of alternative food network in Montréal has created both positive and negative disruptions for existing small-scale producers. Advocates for the expansion of new urban food production and distribution models should therefore give greater consideration to the effects on other actors in the local food system. (shrink)

DNA double‐strand breaks (DSBs) are extremely hazardous lesions for all DNA‐bearing organisms and the mechanisms of DSB repair are highly conserved. In the eukaryotic mitotic cell cycle, DSBs are often present following DNA replication while, in meiosis, hundreds of DSBs are generated as a prelude to the reshuffling of the maternally and paternally derived genomes. In both cases, the DSBs are repaired by a process called homologous recombinational repair (HRR), which utilises an intact DNA molecule as the repair template. Mitotic (...) and meiotic HRR are managed by ‘checkpoints’ that inhibit cell division until DSB repair is complete. Here we attempt to summarise the substantial recent progress in understanding the checkpoint management of HRR in mitosis (focussing mainly on mammals) and then go on to use this information as a framework for understanding the presumed checkpoint management of HRR in mammalian meiosis.

This chapter explores the background ideas are deeply rooted in the history of philosophy, and interact with it in complex ways. It discusses the elements out of which later sociology of knowledge was constructed. The classical sociology of knowledge is an attempt to construct a neutral account of ideology and related concepts. The prime example of an organic period was the medieval period, in which religion, political ideology, and forms of the division of labor and authority fit together as a (...) whole and in which the intellectual aspects of social life justified and explained the social order, which was a productive order and division of labor. K. Mannheim uses the term ideology in a specific way, unlike its later use, and uses the term “utopia” for what would normally be called ideology. Mannheim distinguishes utopia and ideology by saying that ideologies are concrete: in fact they are a lot like practices, or habitus. (shrink)

Coastal ecosystems are increasingly dominated by humans. Consequently, the human dimensions of sustainability science have become an integral part of emerging coastal governance and management practices. But if we are to avoid the harsh lessons of land management, coastal decision makers must recognize that humans are one of the more coastally dependent species in the biosphere. Management responses must therefore confront both the temporal urgency and the very real compromises and sacrifices that will be necessary to achieve a sustainable coastal (...) ecosystem, one that is economically feasible, socially just, and ecologically sound.

Newborn bloodspot screening programs are some of the longest running population screening programs internationally. Debate continues regarding the need for parents to give consent to having their child screened. Little attention has been paid to how meanings of consent-related terminology vary among stakeholders and the implications of this for practice. We undertook semi-structured interviews with parents, healthcare professionals and policy decision makers in two Canadian provinces. Conceptions of consent-related terms revolved around seven factors within two broad domains, decision-making and information (...) attainment. Decision-making comprised: parent decision authority; voluntariness; parent engagement with decision-making; and the process of enacting choice. Information ascertainment comprised: professional responsibilities ; parent responsibilities; and the need for discussion and understanding prior to a decision. Our findings indicate that consent-related terms are variously understood, with substantive implications for practice. We suggest that consent procedures should be explained descriptively, regardless of approach, so there are clear indications of what is expected of parents and healthcare professionals. Support systems are required both to meet the educational needs of parents and families and to support healthcare professionals in delivering information in a manner in keeping with parent needs.

Programs for the reform of K-12 science teaching today usually insist that science teachers must introduce their students to the nature of science, as well as to scientific content. The academic field of science studies, however, evinces no consensus about what the nature of science really is. This article examines how science educators and educational researchers have drawn on the fragmented teachings of science studies about the nature of science, and how they have used those teachings as a resource in (...) their own projects. It identifies three competing movements for the reform of science teaching that owe a particular debt to science studies: history and philosophy of science, science, technology, and society, and constructivist pedagogy. The article analyzes some of the deep assumptions about the relationships between research science, school science, and children’s learning that pervade the educational literature. (shrink)

In the late 1720s, Daniel Turner and James Blondel engaged in a pamphlet dispute over the power of the maternal imagination. Turner accepted the long-standing belief that a pregnant woman's imagination could be transferred to her unborn child, imprinting the foetus with various marks and deformities. Blondel sought to refute this view on rational and anatomical grounds. Two issues repeatedly received these authors' attention: the identity of imagination, and its power in pregnant women; and the process of generation (...) and foetal development. In their discussions of these issues, differences between the authors' acceptance of general medical theories and philosophies became apparent. Blondel invoked Newtonian matter theory, experimental philosophy, and iatro-mechanism, while Turner adhered more to the authority of the Ancients and advocated a more direct role for the Creator as an alternative to mechanism in explaining natural phenomena. Additionally, the authors held differing views of what they regarded as experience. The widespread contemporary interest in their dispute suggests that Turner and Blondel raised the phenomenon of the maternal imagination from an issue of folk belief to a concern of eighteenth-century medicine.

The classic sociological formulation of the “norms of science” was given by Robert K. Merton, in an article originally published as “A Note on Science and Democracy” and reprinted as “Science and Democratic Social Structure” in his Social Theory and Social Structure and as “The Normative Structure of Science” in The Sociology of Science. The formulation is sometimes known by its initials, CUDOS, which stands for the four norms: communism, universalism, disinterestedness, and organized skepticism. Merton's representation of the normative character (...) of science has proved to be one of the most enduring of all sociological analyses. It has been discussed at length by both critics, who proposed the concept of counternorms, and sympathizers, and in the late 1960s and early 1970s became emblematic of the “Mertonian” approach to the social study of science. Nor has it remained static. “Replication” is sometimes called the fifth norm. John Ziman suggested that “originality” be added as a norm, and in many recent explanations of the acronym CUDOS the O is used for originality. (shrink)

A metaphysical scheme which is both a philosophy and a personal religion, presented confessionally in four terse and lyrical essays. The basic concepts are authenticity, solitude, heroism, act, life and death. God is conceived as finite and multiple, engendered through history, "the fundamental meaning toward which converge the most intense fibres of the heroism which forms our history." --L. K. B.

This article explores the issue of jus contra bellum as a particular development within just war thought. At its heart, the jus contra bellum amounts to an attempt to apply the principles of jus in bello (discrimination and proportionality) in order to negate the jus ad bellum. This approach was rather prevalent throughout the Cold War era, as concerns over the prospective use of nuclear weapons facilitated an increasingly sceptical attitude towards the use of force. Whereas the vast majority of (...) just war thinkers have tended to overlook this phenomenon, James Turner Johnson has adeptly recognised the perils of jus contra bellum, and its rather disastrous implications for just war thought. In this respect, Johnson's analysis of this issue constitutes one of his most significant contributions to the tradition. However, as this article will suggest, his assessment of this approach, and consequent efforts to counter it, do not go far enough. As will be noted, the roots of the jus contra bellum can be traced to the prevailing structure of just war thought – a structure which has been consistently championed by virtually every just war thinker.

In lieu of an abstract, here is a brief excerpt of the content:Ius Gentium as Publicly Articulated Moral ScienceMatthew K. MinerdAmong the various types of law discussed in St. Thomas's theological "treatise on law"—questions 90–108 of Summa theologia [ST] I-II—the classification known as the "law of nations" (ius gentium) holds an ambiguous epistemological position. Marking a kind of halfway point between the natural law and civil law, it seems to straddle both domains. In fact, in a particularly important text dedicated (...) to this topic in the ST (I-II, q. 95, a. 4), Aquinas classes the ius gentium as being closely connected to the natural law, though in a way that is somewhat derivative, not as immediately flowing from human nature (especially in its animality) as does the natural law, but also not as marked by human contingency as is human civil law.As was recently discussed in a well-documented and insightful article by Barrett H. Turner in The Thomist, there have historically been two main lines of Thomist interpretation concerning the exact character of the "law of nations." Very broadly stated, what he refers to as the "Salamancan" line, indebted to Francisco de Vitoria, "interprets Thomas's doctrine of the ius gentium as a body of universal positive institutions (that is, specifications, determinationes) added to the natural law by agreement of the human race."1 [End Page 1043] This position, which would be common for several centuries among members of the Thomist school, would locate the law of nations essentially in the domain of nearly universally adopted customs and institutions, not strictly deduced from the natural law, but rather grounded on "the quasi-political authority of the entire human race, which promulgates the ius gentium by customs whose utility for attaining the ends of the natural law under a certain set of social conditions is easily recognized by rational creatures."2Turner calls the other line of thought "Maritain's Neo-Thomist Line,"3 an outlook that would be shared with various nuances by thinkers like Jean-Marie Aubert, Yves Simon, Marie-Michel Labourdette, John Finnis, and others. Setting aside my qualms about his appellation "neo-Thomist," which does more to obscure than to illumine (for it covers a host of Thomistic figures who have significantly different views on what constitutes "Thomism"), Turner does fairly lay out the major lines of Jacques Maritain's position, which is most directly articulated in Man and the State and La loi naturelle ou loi non-écrite.4 Basing himself on his particular view of knowledge of the natural law through connaturality,5 Maritain contrasted this sort of moral cognition with that which develops in the line of conceptual articulation, thus having a different "gnoseological" character from our knowledge of the natural law, while nonetheless still sharing the same "ontological" foundation. Such conceptually articulated law would be the ius gentium.Rather than add my voice to the dialectic of the various thinkers arrayed by Turner into the two aforementioned camps, I would like to propose a slightly different approach to the "moral epistemology of the law of nations," though one that I believe lies in line with the best aspects of Maritain's approach. Continuing a series of reflections that I have undertaken [End Page 1044] concerning moral epistemology during the past few years,6 I propose that it is most helpful to consider the "law of nations" as being a form of reasoning pertaining to what Scholastic vocabulary would refer to as "moral science,"7 namely discursive philosophical reasoning concerning the essences, properties, effects, and various other essential relationships that belong to a human acts, morally considered (the principal subject of moral philosophy), along with other subjects that are studied in relation to this principal subject (e.g., the principles of human acts, most particularly, the structure of human acts and the moral virtues). Moral science is the activity of reasoning that can be undertaken by knowing agents living together in community, seeking to discursively articulate and explain the moral truth that forms the essential basis for the contingent determinations that will then be codified in particular civil laws, the latter of which are not concerned with questions like "what are the ultimate foundations for property...

Stephen Turner complains about weaknesses of Robert K. Merton's teachings without noticing that these are common. He puts down Merton's ideas despite his innovations, on the ground that they are not successful and not sufficiently revolutionary. The criteria by which he condemns Merton are too vague and too high. Merton's merit is in his having put the sociology of science on the map and drawn attention to the egalitarianism that was prominent in classical science and that is now diminished. (...)

Incompatibilists believe free will is impossible if determinism is true, and they often claim that this view is supported by ordinary intuitions. We challenge the claim that incompatibilism is intuitive to most laypersons and discuss the significance of this challenge to the free will debate. After explaining why incompatibilists should want their view to accord with pretheoretical intuitions, we suggest that determining whether incompatibilism is in fact intuitive calls for empirical testing. We then present the results of our studies, which (...) put significant pressure on the claim that incompatibilism is intuitive. Finally, we consider and respond to several potential objections to our approach. (shrink)
