The potential of the soil to hold plant nutrients is governed by the cation-exchange capacity of any soil. Estimating soil CEC aids in conventional soil management practices to replenish the soil solution that supports plant growth. In this study, a multiple model integration scheme supervised with a hybrid genetic algorithm-neural network was developed and employed to predict the accuracy of soil CEC in Tabriz plain, an arid region of Iran. The standalone models and extreme learning machine ) were implemented for (...) incorporation into the MM-GANN. In addition, it was tested to enhance the prediction accuracy of the standalone models. The soil parameters such as clay, silt, pH, carbonate calcium equivalent, and soil organic matter were used as model inputs to predict soil CEC. With the use of several evaluation criteria, the results showed that the MM-GANN model involving the predictions of ELM and ANN models calibrated by considering all the soil parameters as inputs provided superior soil CEC estimates with a Nash Sutcliffe Efficiency = 0.87, Root Mean Square Error = 2.885, Mean Absolute Error = 2.249, Mean Absolute Percentage Error = 12.072, and coefficient of determination = 0.884. The proposed MM-GANN model is a reliable intelligence-based approach for the assessment of soil quality parameters intended for sustainability and management prospects. (shrink)

This chapter examines historical reconstruction and literary structures of rabbinic texts using the Leviticus Rabbah as an example. It explains that Leviticus Rabbah is a commentary on the Book of Leviticus which now forms part of Midrash Rabbah. It proposes ten theses about the special problems which the literary structures of rabbinic texts pose for the historian and analyses a section of the amoraic work of Leviticus Rabbah to describe some of those literary structures. The findings suggest that it is (...) impossible to explain how the textuality of rabbinic sources worked and that many rabbinic works fill the same functional position in a text more than once.

This volume reflects the late Norman Calder's own interests and contributions. It includes articles by scholars who are similarly renowned for their sophisticated and challenging approaches to Arabic and Islamic texts. Also represented are his former students and colleagues working in the field of Rabbinic Studies, which informed his own work.

The same-order representation theory of consciousness holds that conscious mental states represent both the world and themselves. This complex representational structure is posited in part to avoid a powerful objection to the more traditional higher-order representation theory of consciousness. The objection contends that the higher-order theory fails to account for the intimate relationship that holds between conscious states and our awareness of them--the theory 'divides the phenomenal labor' in an illicit fashion. This 'failure of intimacy' is exposed by the possibility (...) of misrepresentation by higher-order states. In this paper, I argue that despite appearances, the same-order theory fails to avoid the objection, and thus also has troubles with intimacy. (shrink)

In this paper, we argue that same is fundamentally different from different, in that same imposes a discourse condition on eventualities, while different compares individuals. This difference has not been noted in previous literature. Furthermore, in the literature on same, there has been a persistent puzzle about the contribution of the definite article with which same must co-occur. We show that this puzzle is resolved once the contribution of same is adjusted to apply to eventualities: then the definite article can (...) be interpreted in the usual way, as generating a presupposition about individuals.

Here I propose a coherent way of preserving the identity of material objects with the matter that constitutes them. The presentation is formal, and intended for RSL. An informal presentation is in preliminary draft! -/- Relative-sameness relations—such as being the same person as—are like David Lewis's "counterpart" relations in the following respects: (i) they may hold between objects that aren't identical (I propose), and (ii) there are a multiplicity of them, different ones of which may be variously invoked in different (...) contexts. They differ from counterpart relations, however, in that they are weak equivalence relations (transitive, symmetric and weakly reflexive). The likenesses to counterpart relations make them suitable for an analysis of de-re temporal and modal predications. The difference renders the resulting counterpart theory immune to standard criticisms of Lewis's Counterpart Theory (e.g., in Hazen 1979, and Fara and Williamson 2005). (shrink)

I formulate an apparent inconsistency between some claims Aristotle makes in his Metaphysics about the sameness and non-sameness relations which obtain between an object and its essence: while a object is not the same as its essence, an essence is thought as being the same as its essence. I discuss different ways in which one may propose to overcome this apparent inconsistency and show that they are problematic. My diagnosis of the problem is that all these putative solutions share the (...) assumption that Aristotle is operating exclusively with the notion of strict numerical identity between an object and its essence, or between definiendum and definiens. I introduce the notion of sameness in nature which holds between an object and its essence, understood as the metaphysical counterpart to the relation of 'being defined as': two items are the same in nature just in case the answer to the 'what is it?' or 'what is its nature/essence?' question is common to both. I argue that the notions of sameness in nature and 'being defined as' need not entail strict identity. Further, they are compatible with, indeed require, the idea that an essence is prior to its essence-bearer, or that a definiens is prior to the relevant definiendum. I conclude that the twin notions of sameness in nature and 'being defined as' successfully defuse the apparent inconsistency formulated at the outset. (shrink)

Parfit’s Branch Line argument is intended to show that the relation of survival is possibly a one-many relation and thus different from numerical identity. I offer a detailed reconstruction of Parfit’s notions of survival and personal identity, and show the argument cannot be coherently formulated within Parfit’s own setting. More specifically, I argue that Parfit’s own specifications imply that the “R-relation”, i.e., the relation claimed to capture of “what matters in survival,” turns out to hold not only along but also (...) across the branches representing the development of a reduplicated person. This curious fact of ‘interbranch survival,’ as I call it, has gone unnoticed so far. The fact that the R-relation also holds across branches creates a trilemma for Parfit’s approach. Either the envisaged notion of personal identity is circular, or the R-relation fails as a reconstruction of the common sense notion of survival, or talk about persons ‘branching’ (being reduplicated etc.) remains semantically empty. In the paper’s last section I suggest that my criticism does not detract from the larger systematic significance of Parfit’s argument. The argument is simply terminologically miscalibrated. Even though Parfit’s branch line argument fails to establish the conceptual separability of survival and identity, it can be used to show the separability of sameness and numerical identity, which should have similar implications for meta-ethics as the original argument.

The axiom of extensionality of set theory states that any two classes that have identical members are identical. Yet the class of persons age i at time t and the class of persons age i + 1 at t + l, both including same persons, possess different demographic attributes, and thus appear to be two different classes. The contradiction could be resolved by making a clear distinction between age groups and cohorts. Cohort is a multitude of individuals, which is constituted (...) within a time interval, and endures throughout part of the time continuum. Age group, on the other hand, is only a reference term to which empirical measurement relates, as in birth or death rates. Accordingly, the two concepts, age group i at t, and age group i + 1 at t + 1, are different. The standard population growth model of Leslie and Lotka, however, does not support such a distinction in age groups. An alternative model, proposed recently, implies precisely such a distinction.

Polls and election results show Americans sharply divided on same-sex marriage, and the controversy is unlikely to subside anytime soon. Debating Same-Sex Marriage provides an indispensable roadmap to the ongoing debate.

In this paper, I present an Aristotelian solution to the problem of material constitution. The problem of material constitution arises whenever it appears that an object a and an object b share all of the same parts and yet are essentially related to their parts in different ways. (A familiar example: A lump of bronze constitutes a statue of Athena. The lump and the statue share all of the same parts, but it appears that the lump can, whereas the statue (...) cannot, survive radical rearrangements of those parts.) I argue that if we are prepared to follow Aristotle in making a distinction between numerical sameness and identity, we can solve the problem of material constitution without recourse to co-location or contingent identity and without repudiating any of the familiar objects of common sense (such as lumps and statues) or denying that these objects have the essential properties we ordinarily think that they have.

I attempt an explication of what it means for an operation across domains to be the same on all domains, an issue that ) took to be central for a successful delimitation of the logical operations. Some properties that seem strongly related to sameness are examined, notably isomorphism invariance, and sameness under extensions of the domain. The conclusion is that although no precise criterion can satisfy all intuitions about sameness, combining the two properties just mentioned yields a reasonably robust and (...) useful explication of sameness across domains.

Locke thought that it was impossible for there to be two things of the same kind in the same place at the same time. I offer (what looks to me like) a counterexample to that principle, involving two ships in the same place at the same time. I then consider two ways of explaining away, and one way of denying, the apparent counterexample of Locke's principle, and I argue that none is successful. I conclude that, although the case under discussion (...) does not refute Locke's principle, it constitutes a serious challenge to it. (shrink)

This paper addresses the progressive, feminist critique of same-sex marriage as articulated by Claudia Card. Although agreeing with Card that the institution of marriage as we know it is profoundly morally flawed in its origins and effects, Callahan disagrees with Card's suggestion that queer activists in the United States should not be working for the inclusion of same-sex couples in the institution.

In Ghaidan v. Godin-Mendoza [2004] U.K.H.L. 30, the U.K. House of Lords upheld the right of a man to succeed to the tenancy of his deceased same-sex partner as if he had been the husband or wife of the deceased. This note examines the five judgements delivered by the court and considers the implications of the decision. It argues that, within the context of family law, Mendoza was a welcome decision but an evolutionary dead-end. The case signals a more promising (...) approach to the development of human rights, but the appropriate use and scope of s.3 of the Human Rights Act 1998 remain somewhat unclear. (shrink)

This chapter endeavors to show that the relevant contrasting term to friend in liberal political theory is not enemy but self. Given the skepticism that suffuses liberal theory, the self remains an endlessly problematic construct that gives us ongoing opportunities for reimagining and reconstructing what the behavior of both friends and enemies is truly like. The chapter examines key terms in the liberal epistemological vocabulary such as skepticism, empiricism, nominalism, and conventionalism to clarify their import for the liberal conceptions of (...) personal identity, friend, and enemy. Throughout, the chapter shows how the Levinasian deployment of the same–other distinction with its devolution upon the concept of infinity offers us a revealing guide to liberal political thought and practice and thereby also constitutes an important implicit critique of Schmitt.

Viewed in its entirety, moral philosophizing, and the moral behavior of people throughout history, presents a curious puzzle. On the one hand, interpersonal duties display a remarkably stable core content: morality the world over enjoins people to keep their word; refrain from violence, theft and cheating; and help those in need. On the other hand, the asserted motives that drive people’s moral actions evince a dazzling diversity: from empathy or sympathy, to practical or prudential reason, to custom and honor, cultural (...) identity, excellence and independence, faith and spirituality, narrative and beauty, and more besides. I term this twin phenomenon—a core of fixed moral duties driven by diverse motives—“moral motive pluralism.” In this article, I marshal evidence to show the prevalence of the phenomenon. Contrary to widespread assumptions, across generations and cultures, diverse motives drive different people to perform their moral duties. But despite this diversity, each different motive impels conscientious compliance with the same core moral duties. I argue this phenomenon undermines key types of evidence commonly employed to justify popular moral philosophies, and provides us with reason to seriously consider certain sorts of ethical theories—especially “functionalist” accounts of morality.

In this paper I examine the concept of cross-temporal personal identity (diachronicity). This particular form of identity has vexed theorists for centuries -- e.g.,how can a person maintain a belief in the sameness of self over time in the face of continual psychological and physical change? I first discuss various forms of the sameness relation and the criteria that justify their application. I then examine philosophical and psychological treatments of personal diachronicity(for example,Locke's psychological connectedness theory; the role of episodic memory) (...) and find each lacking on logical grounds, empirical grounds, or both. I conclude that to achieve a successful resolution of the issue of the self as a temporal continuant we need to draw a sharp distinction between the feeling of the sameness of one's self and the evidence marshaled in support of that feeling.

This book provides a philosophical examination of the extent to which legalizing same-sex marriage can contribute to ending the discrimination and social stigma faced by LGBT men and women in the Western world.

When are two tokens of a name tokens of the same name? According to this paper, the answer is a matter of the historical connections between the tokens. For each name, there is a unique originating event, and subsequent tokens are tokens of that name only if they derive in an appropriate way from that originating event. The conditions for a token being a token of a given name are distinct from the conditions for preservation of the reference of a (...) name. Hence a name may change its reference. Defending the theory requires considerations about the identity of acts, and about empty names and disagreement. The upshot is a causal theory of the identity of names, but not what would normally be counted as a causal theory of the reference of names. Although reference is often transmitted causally, what determines semantic reference is conventionalized speaker-reference. (shrink)

This book explores policy innovation for same-sex couples throughout the Americas and includes same-sex marriage legislation, civil unions, and other new developments for same-sex couples throughout the Americas at both national and sub-national levels. This scholarship is innovative because though much has been written regarding developments in North America, there is very little work dealing with recent developments in the rest of the Americas.

When doing philosophy, there is one norm-like common basis of which we have our pre-theoretic understanding (the “same-object-recognizing” understanding for short) to the effect that, given an object (to be under examination), there is a way that the object objectively is such that we can all talk about that same object even though we may say different things about it, neither resulting in “anything goes” nor bringing about radically different objects thus without genuine engagement. A theoretic examination of the metaphysical (...) issue of the self-identity (as sameness) of given objects (or, in plain words and in a semantic ascent way, “how is it possible to talk about the same object differently?”) can enhance and refine the “same-object-recognizing” understanding as one significant common normative basis of doing philosophy in a constructive-engaging way. In this essay, with relevant theoretic resources of the enhanced account of relative identity and the refined characterization of the law of identity as explained in the recent literature, I examine the metaphysical issue of the self-identity (as sameness) of given objects in two closely related layers, i.e., the “way” layer and the “being” layer of “the way things are” regarding self-identities of given objects. In a holistic way, I first examine several distinct but representative types of (relative) sameness involved in the “way” part of self-identities of given objects; I then focus on five representative types of existential sameness in the “being” part at the “base” level of given objects. Their relation can be highlighted in this way: metaphysically, in the sense to be explained, distinct types of sameness at the “way” layer without existential sameness at the “being”-base layer is “empty” of base, while existential sameness at the “being”-base layer without distinct types of sameness at the “way” layer is “blind” to differentiation.

The paper works out an account of the piety proper to philosophical thought. The investigation proceeds as a critical interpretation of three enigmatic claims made by Martin Heidegger about ‘the piety of thinking,’ but the paper is not simply exegetical; the interpretive work is constantly in service of an attempt to think through the phenomenon independently. Plato’s Euthyphro and Nietzsche’s critique of scientific piety both hover in the background of Heidegger’s pronouncements, and they are given special attention here. Through the (...) investigation, philosophical piety is shown to be a virtuous capacity to respond with fitting submission to the truth as what is insurmountably prior to us. To respond fittingly is, at least, to deal well with sameness and difference, which in the case of piety means to recognize two features of our situation: that philosophical questioning necessarily arises out of a fundamental listening, or affirmation, and that we always belong to being but only ever across a gap.

However liberalism is best understood, liberals typically seek to defend a wide range of liberty. Since same-sex marriage [henceforth: SSM] prohibitions limit the liberty of citizens, there is at least some reason to suppose that they are inconsistent with liberal commitments. But some have argued that it is the recognition of SSM—not its prohibition—that conflicts with liberalism’s commitments. I refer to the thesis that recognition of SSM is illiberal as “The Charge.” As a sympathetic liberal, I take The Charge seriously (...) enough to consider and ultimately reject it. Ultimately, I contend that The Charge is simply misguided and that arguments for it either fail to find support in some liberal principle or else find support from some illiberal principle. (shrink)

Research on culture would be enriched by studying the connection between gender and peer relations. Cultures vary in the roles, privileges, opportunities and rights that are ascribed to females and males. They are known to differ also in the degree to which females and males interact with each other. Although the preference for same-gender peers has been observed across multiple cultural contexts, the degree of this segregation between females and males varies. We argue that variability in the interactional divide between (...) females and males is an important cultural construct that is likely to account for diversity in developmental processes and outcomes.

In this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a form (...) of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

I argue that, under the glitz, dual theories are examples of theoretically equivalent descriptions of the same underlying physical content: I distinguish them from cases of genuine underdetermination on the grounds that there is no real incompatibility involved between the descriptions. The incompatibility is at the level of unphysical structure. I argue that dual pairs are in fact very strongly analogous to gauge- related solutions even for dual pairs that look the most radically distinct, such as AdS/CFT.

Some critics of same-sex marriage allege that this kind of union not only betrays the nature of marriage but that it also opens children to various kinds of harm. Same-sex marriage is objectionable, on this view, in its nature and in its effects. A view of marriage as requiring an unassisted capacity to conceive children may be respect as one idea of marriage, but this view need not be understood as marriage itself. It is not clear, in any case, why (...) government should prefer this one idealized view of marriage over other others, so long as recognition of other kinds of marriage do not stand in the way of government carrying out its core interests, such as the protection of children. The idea that children are necessarily harmed when conceived by and for same-sex couples cannot be sustained as a matter of psychological evidence or moral argument. No research shows that such children are routinely harmed or rarely-but-catastrophically. Comparative accounts of the welfare of children of same-sex couples cannot show either that children must be brought into existence only under ideal circumstances. (shrink)

Proponents of same-sex marriage often defend their view by appealing to the concept of justice. But a significant argument from justice against same-sex marriage can be made also, as follows. Heterosexual union has special social value because it is the indispensable means by which humans come into existence. What has special social value deserves special recognition and sanction. Civil ordinances that recognize same-sex marriage as comparable to heterosexual marriage constitute a rejection of the special social value of heterosexual unions, and (...) to deny such special social value is unjust.

In combining a pluri‐propositionalist framework (Bach‐style) concerning alleged conventional implicatures, and a pluri‐propositionalist framework (Perry‐style) distinguishing various levels of content associated with a single utterance, I defend a Grice‐inspired model of communication. In so doing, I rely on the distinction between what is said, i.e. what is semantically encoded, and what is pragmatically implicated. I show how the notion of same‐saying plays a central role in dealing with problems pertaining to communication insofar as it permits us to posit a stability (...) of content among interlocutors. I also show how people can be classified as same‐sayers in different ways, viz. if they express the same (minimal) proposition/content or if they utter the same sentence. If A utters ‘I'm happy’ and B replies: ‘C said that too’, what B said can mean either that C said that A is happy—thus C and A expressed the same proposition—or that C utters the same words—they both utter ‘I'm happy’ and in so doing express different propositions, i.e. that A is happy and that C is happy respectively.

Sameness and Substance Renewed (hereafter, 2001) is, in effect, a second edition of Wiggins’s 1980 book Sameness and Substance (hereafter, 1980), which in turn expanded and corrected some ideas in his 1967 Identity and Spatio-Temporal Continuity (hereafter, 1967). All three books have similar aims. The first is to argue, primarily against Geach, that identity is absolute not relative. The second is to argue that, despite this, whenever an identity claim a = b is true, there is a sortal f such (...) that a is the same f as b. The biggest difference between 1967 and the two later books is that the later books contain much more detail on what a sortal must be if this claim, called D, is to be both correct and philosophically interesting. The third aim is to apply the first two conclusions to the topic of personal identity. (shrink)

Oregon State University, USA, andrew.valls{at}oregonstate.edu ' + u + '@' + d + ' '//--> In this article, we draw an analogy between the regulation of market language (including official definitions of `organic', `ice cream', and `diamond') and the regulation of the social and legal label `marriage'. Many of the issues raised in the debate over same-sex marriage are less about access to material benefits than about the social and cultural meaning of `marriage'. After reviewing the issues in this debate, (...) we present an analysis of the regulation of language in the marketplace. We discuss the considerations that shape how the state regulates language in the marketplace, if it regulates it at all. Using this framework to analyze the issue of same-sex marriage allows us to identify the costs and benefits of different proposals with regard to marriage, and allows us to distinguish issues that are often conflated. Contrary to its opponents, we argue that making marriage available to same-sex couples does not violate the meaning of `marriage' or destroy marriage, because such a change is similar to many other changes in which words and labels are extended to include new `goods'. This alters the meaning, but does not destroy it, and it does not preclude the possibility of further linguistic innovation to maintain a distinction. Contrary to proponents of same-sex marriage, however, we argue that extending marriage to same-sex couples is not cost-free. There are costs and benefits of any policy on this issue — costs and benefits related to information and status, as well as material resources. Hence, while we agree with advocates of same-sex marriage, we argue that their position involves trade-offs and costs that they sometimes fail to recognize. Key Words: gay marriage • marriage • language regulation. (shrink)

ABSTRACT The idea that the extension of a chemical substance is fixed by determining what stands in the relation of being the same substance to a paradigm sample plays a substantial role in chemistry, and procedures of identification that don’t make direct use of the method can be traced back to ones that do.

Some argue that same-sex marriage is not an equal rights issue because, where same-sex marriage is illegal, heterosexuals and homosexuals have the exact same right to marry—i.e., the right to marry one adult of the opposite sex. I dispute this argument by pointing out that while societies that prohibit same-sex marriage equally permit individual heterosexuals and homosexuals to marry one adult of the opposite sex, same-sex couples in such societies are denied an important right that opposite-sex couples enjoy—i.e., the right (...) to marry. I argue that the right to marry is fundamentally, not an individual right, but a couple’s collective right, analogous to assembly rights. (shrink)

Inferential Role Semantics is often criticized for being incompatible with the platitude that words of different speakers can mean the same thing. While many assume that this platitude can be accommodated by understanding sameness of meaning in terms of similarity of meaning, no worked out proposal has ever been produced for Inferential Role Semantics. I rectify this important omission by giving a detailed structural account of meaning similarity in terms of graph theory. I go on to argue that this account (...) has a number of attractive features, prominent among them that it makes sameness of meaning probabilistically determine co-reference. (shrink)

Nowadays, novel techniques such as Reciprocal effortless in vitro fertilization (ReIVF) enable two individuals to “carry the same pregnancy,” that is to “carry” the same embryo in both their bodies. However, even though these techniques are likely to be increasingly requested, little is known about their safety and efficacy, and much less about their bioethical legitimacy and issues. Considering their uniqueness, this study assesses the compatibility of ReIVF as well as of another similar technique with the classical principles of medical (...) ethics: autonomy, beneficence, nonmaleficence, and justice. The aim is twofold: (i) to start investigating whether these techniques and their underlying reasons are, or could ever be, bioethically justifiable and (ii) to make clinicians and any other potentially interested persons such as researchers, lawmakers and prospective parents themselves are more aware of the health and social implications of using these techniques. Hence, after a brief overview of the technical aspects of the procedures that allow two persons to carry the same pregnancy, this study offers a general moral framework that can be useful for starting to address some relevant aspects of these procedures, such as their benefits and harms on the health of the individuals involved, the reasons behind their use, and the possibility that they might be covered by states in the future. Finally, this study provides a bioethical overview on ReIVF as well as on similar techniques considering different perspectives, while also suggesting some questions and recommendations for further research.

The issue of same-sex marriage continues to be controversial in the United States. Opponents of same-sex marriage offer a variety of objections in defense of their position. One such objection (which I identify as the Inability to Love objection, or ILO) is that legalizing same-sex marriage would promote a counterfeit good (homosexual marriage) as a genuine good (heterosexual marriage), since homosexuals are incapable of genuine, full erotic love. Proponents of ILO argue that homosexuals are incapable of genuine erotic love because (...) all homosexual relationships lack genuine sexual and affective complementarity. Relying on the arguments of Gareth Moore, I argue against ILO, claiming that it rests on an erroneous conception of desire. Once this conception of desire is corrected, the mythof “homosexual desire” is debunked and along with it the main argument in support of the claim that homosexuals are incapable of love. (shrink)
