The idea that biological diversity enhances ecological stability has inspired a huge body of scientific research, from the 1950's and before to the 2000's and beyond. It has also played an important role in environmental ethics, e.g., in Leopold's land ethic. In his view, biodiversity is essential for "a food chain aimed to harmonize the wild and the tame in the joint interest of stability, productivity, and beauty." (1949, p. 199) Then, as now, potential links between (...) class='Hi'>diversity and stability helped to whet the impetus for conservation. (shrink)

The representation of a complex but stable, self-regulated and, finally, harmonious nature penetrates the whole history of Ecology, thus contradicting the core of the Darwinian evolution. Originated in the pre-Darwinian Natural History, this representation defined theoretically the various schools of early ecology and, in the context of the cybernetic synthesis of the 1950s, it assumed a typical mathematical form on account of α positive correlation between species diversity and community stability. After 1960, these two aforementioned concepts and their (...) positive correlation were proposed as environmental management tools, in the face of the ecological crisis arising at the time. In the early 1970s, and particularly after May’s evolutionary arguments, the consensus around this positive correlation collapsed for a while, only to be promptly restored for the purpose of attaching an ecological value on biodiversity. In this paper, we explore the history of the diversity–stability hypothesis and we review the successive terms that have been used to express community stability. We argue that this hypothesis has been motivated by the nodal ideological presuppositions of order and harmony and that the scientific developments in this field largely correspond to external social pressures. We conclude that the conflict about the diversity–stability relationship is in fact an ideological debate, referring mostly to the way we see nature and society rather than to an autonomous scientific question. From this point of view, we may understand why Ecology’s concepts and perceptions may decline and return again and again, forming a pluralistic scientific history. (shrink)

Recent deconstructive developments in ecology (doubts about the existence of unified communities and ecosystems, the diversity-stability hypothesis, and a natural homeostasis or “balance of nature”; and an emphasis on “chaos,” “perturbation,” and directionless change in living nature) and the advent of sociobiology (selfish genes) may seem to undermine the scientific foundations of environmental ethics, especially the Leopold land ethic. A reassessment of the Leopold land ethic in light of these developments (and vice versa) indicates that the land (...) ethic is still a viable environmental ethic, if judiciously updated and revised.

Interferon stimulated gene 15 (ISG15) encodes a ubiquitin‐like protein that is highly induced upon activation of interferon signaling and cytoplasmic DNA sensing pathways. As part of the innate immune system ISG15 acts to inhibit viral replication and particle release via the covalent conjugation to both viral and host proteins. Unlike ubiquitin, unconjugated ISG15 also functions as an intracellular and extra‐cellular signaling molecule to modulate the immune response. Several recent studies have shown ISG15 to also function in a diverse array of (...) cellular processes and pathways outside of the innate immune response. This review explores the role of ISG15 in maintaining genome stability, particularly during DNA replication, and how this relates to cancer biology. It puts forth the hypothesis that ISG15, along with DNA sensors, function within a DNA replication fork surveillance pathway to help maintain genome stability. (shrink)

La spettacolare invasione della parola “biodiversità” nelle sfere scientifiche e politiche così come nei media ha suggerito la possibile nascita di un nuovo campo d’indagine scientifica. Tuttavia, la diversità del mondo vivente è stata l’oggetto di studio della storia naturale sin dai primordi. Gli ecologi non hanno aspettato la pubblicazione di “Biodiversity” di Wilson e Peter, nel 1988, per prendere in esame la diversità delle specie all’interno degli ecosistemi e per occuparsi di questioni fondamentali come i processi di diversificazione e (...) il significato funzionale della diversità specifica. L’analisi degli articoli pubblicati a partire dagli anni Quaranta, fino al 1988, ci permette di comprendere di quali argomenti, relativi al tema della diversità, si sono occupati gli ecologi, e come le intuizioni, gli approcci teorici e la ricerca empirica abbiano interagito. La domanda che si pone è: l’invenzione della biodiversità ha promosso la ricerca? Uno sguardo alle pubblicazioni post-1988 consente di suggerire una risposta. (shrink)

The topic of moral diversity is not only prevalent in contemporary moral and political philosophy, it is also practically relevant. Moral diversity, however, poses a significant challenge for moral theory building. John Thrasher, in his discussion of public reason theory, which includes social contract theory, argues that if one seriously considers the goal of moral constructivism and considerations of representation and stability, then moral diversity poses an insurmountable problem for most public reason theories. I agree with (...) Thrasher that moral diversity poses a significant challenge for orthodox multistage social contract theories. In fact, I even add a further problem for such theories under the assumption of deep moral diversity. Nevertheless, I argue that my recently developed multilevel social contract theory overcomes these problems. I focus on some of the underexplored features of this theory to show that multilevel social contract theory offers one conceptually coherent and plausible way to render social contract theory viable and relevant for modern diverse societies.

The neutral theory of biodiversity assumes that coexisting organisms are equally able to survive, reproduce and disperse, but predicts that stochastic fluctuations of these abilities drive diversity dynamics. It predicts remarkably well many biodiversity patterns, although substantial evidence for the role of niche variation across organisms seems contradictory. Here, we discuss this apparent paradox by exploring the meaning and implications of ecological equivalence. We address the question whether neutral theory provides an explanation for biodiversity patterns and acknowledges causal processes. (...) We underline that ecological equivalence, although central to neutral theory, can emerge at local and regional scales from niche-based processes through equalizing and stabilizing mechanisms. Such emerging equivalence corresponds to a weak conception of neutral theory, as opposed to the assumption of strict equivalence at individual level in the strong conception. We show that this duality is related to diverging views on hypothesis-testing and modeling in ecology. In addition, the stochastic dynamics exposed in neutral theory are pervasive in ecological systems and, rather than a null hypothesis, ecological equivalence is best understood as a parsimonious baseline to address biodiversity dynamics at multiple scales.

Postcolonialism and decolonising campaigns are expressions of human pain on the level of identity confusion (inferiority), ideological abuse (cultural discrimination) and structural oppression (imperialistic exploitation). The slogan ‘Black Pain is a White Commodity’ in the #MustFall campaigns is critically analysed within the framework of postcolonial theory and imperialistic power categories. The basic hypothesis of the article is that in early Christianity, pantokrator images of God were influenced by iconography stemming mostly from the Roman Emperor cult and Egyptian mythology. The (...) power (omnipotence) and dominiumship of God directly and indirectly played a role in Christian imperialistic thinking regarding the expansion of the Kingdom of God and missio Dei strategies during times of European and colonial expansionism. In order to address the quest for ‘moving beyond’ in postcolonial theory, the impact of pantokrator-images of God on ecclesial thinking is researched. In order to contribute to sustainability and stability within the complexity of cultural diversity and current civil unrest on campuses in South Africa, the paracletic notion of compassionate being-with is developed within the framework of practical theological thinking. Instead of a Caesar-depiction, the theological notion of passio Dei is proposed: the decolonialising (post-imperialising) God. (shrink)

Policy-makers face an uncertain world. One way of getting a handle on decision-making in such an environment is to rely on evidence. Despite the recent increase in post-fact figures in politics, evidence-based policymaking takes centre stage in policy-setting institutions. Often, however, policy-makers face large volumes of evidence from different sources. Robustness analysis can, prima facie, handle this evidential diversity. Roughly, a hypothesis is supported by robust evidence if the different evidential sources are in agreement. In this thesis, I (...) strengthen the case for the use of robustness analysis in evidence-based policymaking by answering open research questions about this inference technique. First, I argue that existing taxonomies miss a fruitful category of robustness reasoning, that is predictive stability. Second, I claim that derivational robustness analysis – the investigation of whether the results of different models are in agreement – can yield interesting insights even if not the entire relevant model space is covered by available models or if the model results are only partially in agreement. Third, I claim that expert knowledge is necessary to address questions that arise when one applies measurement robustness analysis – the investigation into whether multiple means of measurement yield the same result. Finally, I argue that, in situations where evidence from different measurements is not in agreement, it can be advisable to no longer take all of the evidence into account. This can be done in a rationally defensible way by choosing the most adequate theory or model underlying parts of the evidence set. I discuss examples from climate, medical, and economic policy-making to establish my claims. (shrink)

The remarkable transition from helpless infant to sophisticatedfive-year-old has long captured the attention of scholars interested inthe discovery of knowledge. To explain these achievements, developmentalpsychologists often compare children's discovery procedures to those ofprofessional scientists. For the child to be qualified as a ``littlescientist'', however, intellectual development must be shown to derivefrom rational hypothesis selection in the face of evidence. In thepresent paper we focus on one dimension of rational theory-choice,namely, the relation between hypothesis confirmation and evidencediversity. Psychological research (...) suggests cultural variability inappreciating evidence diversity and lack of such appreciation by youngchildren. Before reaching conclusions about the ``little scientist''thesis, however, it is essential to normatively analyze the diversityissue. We undertake such an analysis within a Bayesianperspective.

Protein synthesis inhibitors prolong the half‐lives of most mRNAs at least fourfold in the somatic cells of higher eukaryotes and in yeast cells. Some mRNAs are stabilized because the inhibitors affect mRNA‐specific regulatory factors; however, hundreds or thousands of other mRNAs are probably stabilized by a common mechanism. We propose that mRNA stabilization in cells treated with a translation inhibitor reflects a physiological process that occurs during each mitosis and is important for cell survival. Transcription and translation rates decline drastically (...) during a 1–2 hour interval of mitosis. We hypothesize that translational repression during this interval somehow inactivates a critical component of the mRNA degradation machinery. As a result, mRNA half‐lives are prolonged during the interval when transcription is repressed. If labile mRNAs were not stabilized during mitosis they, and perhaps also the labile proteins they encode, would be depleted as the cell entered G1 phase, with deleterious consequences. Stabilization during mitosis, or in response to translation inhibitors, thus preserves the capacity of the cell to synthesize essential proteins as it enters G1 or recovers from inhibitor treatment. mRNA stabilization might serve a similar purpose during starvation or any stress negatively affecting translation.

Genetic diversity of viral populations is almost unanimously attributed to the build‐up of random mutations along with accidental recombination events. This passive role of viruses in the selection of viable genotypes is widely acknowledged. According to the hypothesis presented here, populations of steady‐state error copies of a master viral sequence would have a dominant mutant rather than a random pool of heterogeneous viral genomes with changes scattered uniformly without any preferential distribution. It would let viruses face the selection (...) stage of host surveillance having a preceding set of potential survivors or “guard” genomes among an ordinary cloud of random quasispecies. (shrink)

John Rawls's transition from A Theory of Justice to Political Liberalism was driven by his rejection of Theory's account of stability. The key to his later account of stability is the idea of public reason. We see Rawls's account of stability as an attempt to solve a mutual assurance problem. We maintain that Rawls's solution fails because his primary assurance mechanism, in the form of public reason, is fragile. His conception of public reason relies on a condition (...) of consensus that we argue is unrealistic in modern, pluralistic democracies. After rejecting Rawls's conception of public reason, we offer an ‘indirect alternative’ that we believe is much more robust. We cite experimental evidence to back up this claim. (shrink)

Workforce diversity has received increasing amounts of attention from academics and practitioners alike. In this article, we examine the empirical association between a firm’s workforce diversity and the degree of religiosity of the firm’s management by investigating their unidirectional and endogenous effects. Employing a large and extensive U.S. sample of firms from the years 1991–2010, we find a positive association between a measure of the firm’s commitment to diversity and the religiosity of the firm’s management after controlling (...) for various firm characteristics. In addition, after controlling for endogeneity with the dynamic panel generalized method of moment, we still find a positive association between the firm’s diversity and management’s religiosity. We interpret these results as supportive of the religious motivation explanation that views the firm as a human community and considers religion as a factor that influences managers to more positively embrace diversity. Our results, however, provide no support for the resource-constraint hypothesis that views the firm as a nexus of contracts and sees managers as aiming to maximize shareholder returns under resource constraints that force them to invest only in projects that have a positive net present value and reject diversity initiatives since these do not have a positive NPV.

Grossberg and VanDieren have started a program to develop a stability theory for tame classes. We name some variants of tameness and prove the following. Let K be an AEC with Löwenheim-Skolem number ≤κ. Assume that K satisfies the amalgamation property and is κ-weakly tame and Galois-stable in κ. Then K is Galois-stable in κ⁺ⁿ for all n<ω. With one further hypothesis we get a very strong conclusion in the countable case. Let K be an AEC satisfying the (...) amalgamation property and with Löwenheim-Skolem number ℵ₀ that is ω-local and ℵ₀-tame. If K is ℵ₀-Galois-stable then K is Galois-stable in all cardinalities.

We address the biological dynamics problem of the persistence of several species in conditions of non-existence of an equilibrium, including an example of stabilization by predation and the very controversial “competitive exclusion”. We give normal forms for various examples of such persistence and comments on the involved topology, which implies the presence of exceptional heteroclinic connections binding equilibria on the boundary.

Change is endemic in nature yet scientists seek stability amidst change. When proposals fail scientists shift their focus and look for stability elsewhere. Scholars who study the development of science also seek stability in the scientific process. Here I explore the interaction between stability and change in nature as we understand it through the sciences and in the practice of scientific research. The concluding part argues that the search for stability meets a human intellectual need (...) but this is compatible with our finding what is actually there. Cases in which a previously accepted part of science is rejected or revised in response to contrary data indicates that we do not predetermine outcomes of observations and experiments. Still, the belief that there are loci of stability in nature is a working hypothesis. While it has been fruitful, only future scientific developments can determine if this will continue to hold.

In myrecent book I have sought to define a notion of stability and to argue that it is a useful notion for biomedical and especially epidemiological research (Broadbent 2013, 56–80). In this paper I seek to defend the notion of stability against two possible objections: that it fails to be epistemically significant, and that it amounts to nothing more than empirical adequacy. I argue that stability is epistemically significant because to know that a hypothesis is stable (...) is to know something about the world, even if not the truth of the hypothesis. I argue that knowledge of stability of a hypothesis is distinct from knowledge of its approximate truth. And I argue that asserting the stability of a hypothesis is distinct from asserting its empirical adequacy, because it allows that the hypothesis may still be implicated in empirically inadequate claims, entailing only that if the hypothesis is so implicated, it will not be revised soon.

We examine how social diversity and inclusiveness on corporate boards affect corporate performance and monitoring in Sri Lanka, a country subject to decades of polarization, civil war, and even genocide. Barely more than a decade after the civil war, we find that board social diversity on the basis of ethnicity, religion, language, gender, and nationality of the board members is positively related to corporate performance, both in terms of stock market performance and accounting returns, and to corporate financial (...) stability. The main positive effects of social diversity derive from ethno-linguistic inclusiveness. The results are confirmed by an instrumental variable approach that addresses endogeneity issues. We find no evidence that inter-personal and moral conflicts or communication problems among board members negatively affect firm performance. (shrink)

Contemporary society involves a number of different persons, groups, and ways of life that are deeply divided and very often opposed on fundamental matters of deep concern. Today, many contemporary philosophers regard this 'fact of diversity' as a problem that needs to be addressed when assessing the principles employed to organize society. In this paper, I discuss the fact of diversity, as it is understood by the notion of reasonable pluralism, and explain why it is thought by some (...) to challenge the stability of a society's political morality. I examine the leading attempt to offer an account of the stability of a political morality and I argue that John Rawls's attempt to account for the stability of Justice as Fairness fails for reasons applicable to all political moralities because the very notion of a stable political morality is implausible. Diversity, as reasonable pluralism understands it, is not a problem that can be solved either by identifying a stable political morality or by modifying a political morality in some way that will make it more stable. Instead, the fact of diversity indicates only that disagreements on all aspects of society's organization, including its organizing principles and matters of value, is a permanent feature of social life that cannot be ignored, wished away, or solved.

The literature on gender diversity on corporate boards is growing, yet firms' motivation for achieving such diversity remains underexplored. This study examines the potential objective behind appointing female directors that could be driven by organizational impression management based on the hypothesis that firms strategically propose to nominate female directors when they need to form a favorable impression to their stakeholders, especially in relation to executive compensation. This study analyzed annual shareholders meeting agendas for 3585 listed Japanese firms (...) between 2011 and 2020 and found that firms placed female director appointments on the meeting agenda when they needed approval for the revision of executive compensation. This tendency was strengthened for firms with more outside directors. This study's approach and findings contribute to the literature on corporate board gender diversity by suggesting organizational impression management as a potential strategic motivation behind the appointment of female directors.

This article investigates the gender diversity of the corporate board of European Union banks. Employing a large sample of 612 European banks from 20 European countries, it identifies organizational characteristics that could be predictive of women’s presence on bank boards. We identify three factors that play a particularly important role in defining bank board gender diversity. First, the proportion of women on the board is higher for lower-risk banks. We argue that there may be some statistical discrimination behind (...) this relation, although it could also be explained by a real risk-aversion hypothesis. Second, banks with larger boards have a higher proportion of women on their boards, which could be considered a signal of some kind of preference for homogeneity on small boards. Finally, banks that have a growth orientation are more prone to include women on their board, since they may be seen as providers of diverse external resources that are more valued by firms operating under critical circumstances.

We initiate a systematic investigation of the abstract elementary classes that have amalgamation, satisfy tameness, and are stable in some cardinal. Assuming the singular cardinal hypothesis, we prove a full characterization of the stability cardinals, and connect the stability spectrum with the behavior of saturated models.We deduce that if a class is stable on a tail of cardinals, then it has no long splitting chains. This indicates that there is a clear notion of superstability in this framework.We (...) also present an application to homogeneous model theory: for [Formula: see text] a homogeneous diagram in a first-order theory [Formula: see text], if [Formula: see text] is both stable in [Formula: see text] and categorical in [Formula: see text] then [Formula: see text] is stable in all [Formula: see text].

In deliberative argument, in political discourse, in teaching, and in casual conversation, as rhetors we often hope that our attempts at interaction will have some effect on the participants in these discursive environments. The phenomena of stubbornness, however, would seem to suggest that, despite our efforts, there are times when rhetoric just doesn't work. This dissertation complicates this premise, and in so doing complicates common understandings of both stubbornness and rhetorical effect. As I argue, rhetorical effects exist within a complex (...) rhetoric system, within which they circulate and are interconnected with a diversity of other rhetorical and non-rhetorical elements. Using N. Katherine Hayles's concept of "making the cut," I argue that within such complex systems, stability and change are tangled up in an interdependent relationship; in short, in order for complexity to exist it must be constrained by contingent stabilities. These necessary stabilities mask the way that systems are always moving, and so we often do not see changes in the rhetoric systems we inhabit. In this sense, these changes are compensatory, and they work to maintain a stability that can manifest precisely as stubbornness. In delineating what I call a "rhetoric-systems" approach, this dissertation maps the stabilities and movements of several different rhetoric systems, and provides new insight into the complex and relational movement of rhetorical effect. Our use of this approach asks us to recognize the existence and value of certainty and stability, and then to pull back and recognize the existence of complexity and change. The approach integrates insights from systems theory into existing rhetorical theory, and in so doing models an interdisciplinary approach to public rhetorics and writing studies that is firmly grounded in rhetorical theory.

An aim of science is to increase our understanding of the natural world. A primary means for doing so is by providing explanations, which often proceed by tracing the causes of phenomena. How can a causal explanation lead to understanding? While explanations can take many forms, I argue that to succeed they must embody a conception of causation shared with their audience. The challenge then, is to describe this conception and detail its role in explanation. While there is good evidence (...) that scientists employ more than one causal concept, I argue that the concept of productive causation (centered on the notion of bringing about change via a connection) has a primary role in natural science explanations. After critiquing other philosophical accounts, I develop a new theory of productive causation and show how it provides an underpinning for successful explanations. The heart of the theory is a network of persisting processes that possess dispositions toward change-producing mutual interactions. I argue that in a good explanation, the scientific entities, properties and activities invoked will correspond to the theory’s depiction of causal structure. One important dimension of the theory describes how repeated patterns of interaction can give rise to a hierarchy of composite processes. This allows the theory to account for stabilized entities at various spatio-temporal scales. In turn, this enables the approach to be applicable throughout the natural sciences. After starting with simple examples, I show how the theory deals with more challenging cases from physics to biology. I conclude that the approach illuminates how explanations of various forms across diverse disciplines can lead to scientific understanding. (shrink)

Public reason theories are characterized by three conditions: constructivism, representation, and stability. Constructivism holds that justification does not rely on any antecedent moral or political values outside of the procedure of agreement. Representation holds that the reasons for the choice in the model must be rationally explicable to real agents outside the model. Stability holds that the principles chosen in the procedure should be stable upon reflection, especially in the face of diversity in a pluralistic society. Choice (...) procedures that involve at least two-stages with different information, as Rawls’s theory does, will be path-dependent and not meet the condition of representation since it will not be globally coherent. Attempts to solve this problem without eliminating the segmentation of choice in the procedure will run afoul of constructivism or stability. This problem is instructive because it highlights how public reason theories must evolve in the face of increased concerns about diversity. (shrink)

Andrew Wayne discusses some recent attempts to account, within a Bayesian framework, for the "common methodological adage" that "diverse evidence better confirms a hypothesis than does the same amount of similar evidence". One of the approaches considered by Wayne is that suggested by Howson and Urbach and dubbed the "correlation approach" by Wayne. This approach is, indeed, incomplete, in that it neglects the role of the hypothesis under consideration in determining what diversity in a body of evidence (...) is relevant diversity. In this paper, it is shown how this gap can be filled, resulting in a more satisfactory account of the evidential role of diversity of evidence. In addition, it is argued that Wayne's criticism of the correlation approach does not indicate a serious flaw in the approach. (shrink)

One of the leading explanations for Canadian banking stability through the global financial crisis of 2007–08 is the Concentration-Stability Hypothesis (CSH), according to which the oligopoly of Canadian finance stabilised the credit system by cushioning it with above-average profits. These provided a buffer against fragility and incentives against excessive risk-taking. In this article, I critically examine CSH and show that classical Marxian analysis more effectively illuminates Canadian banking stability. I demonstrate that robust corporate profitability and capital (...) accumulation before the crisis strengthened the balance sheets of the banks and supported them through those turbulent years. Thus, financial stability is linked explicitly to broader economic stability, and the latter is linked to the profitability of business enterprise. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Hypothesis Concerning the Character of Islamic ArtAsli GocerWhy Islamic art has the distinctive features it has continues to generate clashing explanations. The Islamic visual treasury has no figural images, for instance, and three-dimensional sculpture or large scale oil painting, but instead contains miniatures, vegetal ornaments, arabesque surface patterns, and complex geometrical designs. To account for the phenomena the following radically opposing theories have been offered: the influence (...) of Judaism, the Quranic prohibition against making images, 1 Islamic resentment of the glory of Byzantine icons, 2 logocentricism of classical Islam, 3 the spiritual dimension of Islam, 4 tacit Islamic assertion of “otherness,” 5 and contingency of history. 6 The merits of these theories have been roundly discussed in the literature, and so I will not repeat the task here. I will insist that none of these theories offer a coherent explanation for all arts, but my presumption is that such an explanation is possible. In nonvisual arts the Muslim prefers simple tunes over that of the symphony, for instance, whirling dervishes over the ballet, and lyric poetry over dramatic literature. In my view what explains the common characteristic of all these arts is a certain kind of Islamic attitude informed by a certain philosophical outlook. Although it would be hasty to suggest the existence of a monolithic [End Page 683] Islamic art, it would be equally rash to deny some striking commonalities among its diverse examples. 7The following observation by a Muslim scholar is notable in this regard: “Whether in the great courtyard of the Delhi Mosque or the Qarawiyyin in Fez, one feels oneself within the same artistic and spiritual universe despite all the local variations in material, structural techniques, and the like.” 8 Some cite geometry as what mediates that feeling to the observer despite the cultural divergences in style. 9 Even those who have given up the search for the universal or the spiritual in Islamic art cannot help but see in it the classical ideal of beauty. 10 It is this classical heritage that in fact holds one of the important keys to the puzzle at hand. In particular I shall claim that Islamic art is the living image of what Plato has in mind for art in a theocratic state. Clearly, to refer to Plato and art in the same breath invites trouble. As is well enough known, giving a general interpretation of Plato’s views on the nature of art is a very complex endeavor. 11 Even in the face of grave difficulties in textual exegesis, however, there is sufficient evidence that Plato has some settled views on art. Those pertinent to our discussion here involve two claims, that beauty and goodness are divine and that all human endeavor (including artistic creation) must imitate the divine. 12 Although Platonic strain in Islam has been noted in other areas, its persistent legacy has been overlooked in art. 13 I shall argue that the Platonic influence on Islamic thought can be traced not only to political philosophy 14 and geometry, 15 as it has been commonly accepted, but also aesthetics. 16 A philosophical explanation of the Islamic attitude toward art may therefore be derivable from the Platonic axiom that god is the paradigm of beauty, which is the cosmological principle of [End Page 684] order and harmony; and as all created things, art, too, must reflect the divine paradigm.Before defending this ahistorical hypothesis on the character of Islamic art so reviled in recent literature, a few caveats are in order. “Islamic art” contains redundant terms. Strictly speaking all art in Islam is “Islamic,” because for the Muslim art is a crucial point of contact with the divine. That art should direct the mind to the divine is also Plato’s view. 17 Second, the categories that have traditionally been used to describe Islamic art such as “aniconic” and “nonrepresentational” are unhelpful for the problem at hand. 18 When it comes to the issue of iconography in Islamic arts, there is no consensus, for Islamicists are notably divided on the semiotic dimension of the Islamic visual language. The question of whether the geometric surface pattern is essentially iconography, for instance, is yet... (shrink)

The study area was a small lowland river valley (the Łęg river) located in the south-east of Poland. The object of investigation was the macrophytes of 10 river lakes with corresponding active river channel stretches of the same length as the cut-offs. The aim was to check the difference in species diversity between cut-off and active river channels. The second aim was to test the following hypothesis: vegetation of river lake has been shaped under the influence of contiguous (...) river stretch which has left a measurable mark in species abundance and composition. To test this, we checked whether a cut-off channel’s flora is more similar to flora of the contiguous river stretch, than to flora of a farther river stretch. During the course of the study it was found that the average species richness was approximately two times higher in the cut-off channels than in the river stretches. The number of the species exclusive for the river lakes was nine times higher in comparison with the river’s exclusives (not found in the cut-offs). The Shannon diversity index definitely spoke in favor of the river lakes. These results clearly show the significance of river lakes in maintaining biodiversity of aquatic ecosystems in a small river valley. We did not confirm our hypothesis concerning floristic relation between an active channel and its cut-offs. The floristic similarity between a given cut-off channel and the contiguous active river channel stretch is not stronger than the similarity between this lake and more distant river stretches. The cause of such a state of affairs may be high natural dynamics of investigated habitats and anthropogenic transformation of the river valley. (shrink)

"Biophilia" is the term coined by Edward O. Wilson to describe what he believes is humanity's innate affinity for the natural world. In his landmark book Biophilia, he examined how our tendency to focus on life and lifelike processes might be a biologically based need, integral to our development as individuals and as a species. That idea has caught the imagination of diverse thinkers. The Biophilia Hypothesis brings together the views of some of the most creative scientists of our (...) time, each attempting to amplify and refine the concept of biophilia. The variety of perspectives -- psychological, biological, cultural, symbolic, and aesthetic -- frame the theoretical issues by presenting empirical evidence that supports or refutes the hypothesis. Numerous examples illustrate the idea that biophilia and its converse, biophobia, have a genetic component: fear, and even full-blown phobias of snakes and spiders are quick to develop with very little negative reinforcement, while more threatening modern artifacts -- knives, guns, automobiles -- rarely elicit such a response people find trees that are climbable and have a broad, umbrella-like canopy more attractive than trees without these characteristics people would rather look at water, green vegetation, or flowers than built structures of glass and concrete The biophilia hypothesis, if substantiated, provides a powerful argument for the conservation of biological diversity. More important, it implies serious consequences for our well-being as society becomes further estranged from the natural world. Relentless environmental destruction could have a significant impact on our quality of life, not just materially but psychologically and even spiritually. (shrink)

Rawls addresses the problem of the stability of his conception of justice by arguing that it could become the focus of an “overlapping consensus,” in which individuals with diverse moral, philosophical, and religious views all accept the Rawlsian conception for different reasons. Using the example of Christian fundamentalists, I show that, subject to constraints that Rawls himself delineates, no such consensus is possible.

Entertaining diverse assumptions about empirical research, commentators give a wide range of verdicts on the NHSTP defence in Statistical significance. The null-hypothesis significance- test procedure is defended in a framework in which deductive and inductive rules are deployed in theory corroboration in the spirit of Popper's Conjectures and refutations. The defensible hypothetico-deductive structure of the framework is used to make explicit the distinctions between substantive and statistical hypotheses, statistical alternative and conceptual alternative hypotheses, and making statistical decisions and drawing (...) theoretical conclusions. These distinctions make it easier to show that H0 can be true, the effect size is irrelevant to theory corroboration, and “strong” hypotheses make no difference to NHSTP. Reservations about statistical power, meta-analysis, and the Bayesian approach are still warranted. (shrink)

This paper explores the underrepresentation of women and minorities in academic philosophy. Specifically, it focuses on why, given the relatively even male/female ratio at undergraduate level, women are underrepresented at every level above this. It addresses some of the misconceptions and myths surrounding women in philosophy, including those surrounding the discussion of the different‐intuition hypothesis. It also explores the ways in which feminist research in philosophy is subject to marginalisation as a result of systematic exclusionary practices typical of the (...) dominant culture of justification within traditional philosophy. It argues for the necessity of an intersectional approach, and the importance of taking seriously the psychological and sociological analysis of underrepresentation, in order to improve both the experience and the representation of women and other minorities at all levels of professional philosophy, as well as of the discipline as a whole.

The value of varied evidence, I propose, lies in the fact that more varied evidence is less coherent on the assumption of the negation of the hypothesis under consideration than less varied evidence. I contrast my own analysis with several other Bayesian analyses of the value of evidential diversity and show how my account explains cases where it seems intuitively that evidential variety is valuable for confirmation.

This book has its philosophical starting point in the idea that group-based social movements have positive implications for peace politics. It explores ways of imagining community, nation, and international systems through a political lens that is attentive to diversity and different lived experiences. Contributors suggest how groups might work toward new nonviolent conceptions and experiences of diverse communities and global stability.

Harry Eckstein’s long-standing (but ever-changing) hypothesis that a nation’s political stability is a function of “congruence” between the “authority patterns” exhibited by the government and those displayed by nearly every sort of institution under that government’s aegis involved a highly complex politico-psychological theory. As a result, it was quite difficult either to confirm or disconfirm. While there have been a number of suggested revisions that apparently simplify his thesis, they suffer either from vagueness or a failure to take (...) democracy to be a system that requires an actual commitment to majoritarianism. In this paper a revision is offered that utilizes a small number of completely dichotomous variables that are easily subject to empirical tests. This revised theory (of “consonance” rather than congruence) is also explicitly majoritarian, enabling it to shed light on the essential nature of democratic regimes. (shrink)

There is broad anthropological interest in understanding how people define “insiders” and “outsiders” and how this shapes their attitudes and behaviors toward others. As such, a suite of hypotheses has been proposed to account for the varying degrees of in-group preference between individuals and societies. We test three hypotheses related to material insecurity, pathogen stress, and views of gender equality among cross-sectional and longitudinal samples of young people in Ethiopia to explore stability and change in their preferences for coethnic (...) spouses. We show that food insecurity is associated with a greater likelihood of intolerant mate preferences. We also find that young people who hold more gender equitable attitudes tended to hold more tolerant mate preferences. Finally, we find no support for the hypothesis that expected pathogen exposure is associated with intolerant mate preferences. Our results most strongly support a material insecurity hypothesis of in-group bias, which assumes that uncertainty over meeting basic needs leads people to favor those in their in-group. As such, our findings join a small but growing group of studies that highlight the importance of material insecurity for understanding tolerance, xenophobia, in-group bias, and favoritism. (shrink)

Human fascination with art has deep evolutionary roots, yet its role remains a puzzle for evolutionary theory. Although its widespread presence across cultures suggests a potential adaptive function, determining its evolutionary origins requires more comprehensive evidence beyond mere universality or assumed survival benefits. This paper introduces and tests the Collector Hypothesis, which suggests that artworks serve as indicators of collectors’ surplus wealth and social status, offering greater benefits to collectors than to artists in mating and reproductive contexts. Our study (...) among Indigenous Papuan communities provides preliminary support for the Collector Hypothesis, indicating that, compared to artists, collectors are perceived as having higher social status and greater attractiveness to women. These findings provide unique insights into Papuan communities and contribute to the ongoing discussion about art’s adaptive significance of art by suggesting that artistic capacities may benefit not only creators but also those who accumulate and display art. Further research in diverse cultural contexts is needed for a comprehensive understanding of this interplay. (shrink)

A recent thought‐provoking theory argues that complex organisms using epigenetic information for their normal development and functioning must irreversibly age as a result of epigenetic signal loss. Importantly, the scope of this theory could be considerably expanded, with scientific benefits, by analyzing epigenetic ageing beyond the borders of the Tree of Life. Viruses that use epigenetic signals for their normal functioning may also age, that is, present an increasing risk of failing to complete their individual life cycle and to disappear (...) with time. As viruses are ancient, abundant, and infect a considerable diversity of hosts, the ageing virus hypothesis, if verified, would have important consequences for many fields of the Life sciences. Uncovering ageing viruses would integrate the most abundant and biologically central entities on Earth into theories of ageing, enhance virology, gerontology, evolutionary biology, molecular ecology, genomics, and possibly medicine through the development of new therapies manipulating viral ageing.

This research study investigates the implementation of the Conflict Management Socialization and Mapping of Conflict Prone Areas program by the National Unity and Political Affairs Agency (Bakesbangpol) in Kuningan Regency, Indonesia. Using qualitative methods, including interviews and a literature review, the study examines how Bakesbangpol Kuningan detects and manages potential conflicts to maintain regional stability. Findings reveal that the program effectively utilizes early detection initiatives and community engagement forums such as Focus Group Discussions (FGDs) and collaborates with various stakeholders, (...) including local authorities and community organizations. Creating a conflict-prone area map in 2017 is a vital tool for proactive conflict prevention and policy formulation. However, the study identifies areas for enhancement, including further staff training, robust administrative support systems development, and more decisive leadership in program execution. This research highlights the significance of systematic program implementation and collaborative efforts in managing social conflicts and ensuring sustained regional harmony. It contributes to the field by providing insights into effective conflict management strategies at the local level in Indonesia, particularly in diverse and potentially conflict-prone regions like Kuningan.

This article investigates how firms address the stability-change paradox inherent in sustainability transitions through the maintenance and utilization of a portfolio of sustainability-oriented partnerships. Drawing on a retrospective case study of Dong/Ørsted, a Danish energy company, we demonstrate the varying manifestations of the stability-change paradox during different phases of the company’s transition, influenced by both exogenous and endogenous factors. Furthermore, our findings reveal how Dong/Ørsted employed their partnership portfolio to implement diverse responses to manage the paradox. Based on (...) these findings, we argue that partnership portfolios can serve as spatiotemporal pockets, enabling organizations to effectively address and leverage the temporal and spatial aspects inherent in sustainability paradoxes. In addition, we highlight how partnership portfolios facilitate sustainability transitions by creating and leveraging different forms of collaborative value. (shrink)

We address the puzzle of “unity in diversity” in human languages by advocating the (minimal) common denominator for the diverse expressions of transitivity across human languages, consistent with the view that early in language evolution there was a modest beginning for syntax and that this beginning provided the foundation for the further elaboration of syntactic complexity. This study reports the results of a functional MRI experiment investigating differential patterns of brain activation during processing of sentences with minimal versus fuller (...) syntactic structures. These structural layers have been postulated to represent different stages in the evolution of syntax, potentially engaging different brain networks. We focused on the Serbian “middles,” analyzed as lacking the transitivity (vP) layer, contrasted with matched transitives, containing the transitivity layer. Our main hypothesis was that transitives will produce more activation in the syntactic (Broca's–Basal Ganglia) brain network, in comparison to more rudimentary middles. The participants ( n = 14) were healthy adults (Mean age = 33.36; SD = 12.23), native speakers of Serbo-Croatian. The task consisted of reading a series of sentences (middles and transitives; n = 64) presented in blocks of 8, while being engaged in a detection of repetition task. We found that the processing of transitives, compared to middles, was associated with an increase in activation in the basal ganglia bilaterally. Although we did not find an effect in Broca's area, transitives, compared to middles, evoked greater activation in the precentral gyrus (BA 6), proposed to be part of the “Broca's complex.” Our results add to the previous findings that Broca's area is not the sole center for syntactic processing, but rather is part of a larger circuit that involves subcortical structures. We discuss our results in the context of the recent findings concerning the gene-brain-language pathway involving mutations in FOXP2 that likely contributed to the enhancement of the frontal-striatal brain network, facilitating human capacity for complex syntax.

The readability of 10-K reports, in terms of linguistic complexity, determines the usefulness of information disclosure for stakeholders, particularly individual investors. Since investors largely depend on the financial communication in 10-K reports, firms have an ethical and legal responsibility to present disclosures in a language investors can understand. However, motivated by self-interest, managers obfuscate such disclosures to mask their own actions and hide unfavourable information. Building on the managerial obfuscation hypothesis grounded in stakeholder-agency and ethical-sensitivity theories, I hypothesize and (...) empirically test the relationship between board gender diversity and the readability of narrative disclosure in 10-K reports. Based on a relatively large sample of Russell 3000 firms for the years 2002–2018, I find a significant positive impact of BGD on 10-K reports’ readability, which in turn improves firm performance. Channel analysis reveals that the findings are driven by female independent directors, and their representation on audit and compensation committees; however, board activity does not appear to drive this relationship. Finally, I find that although gender discrimination in the appointment of directors spurs complex readability, the BGD-readability relationship is consistent in gender-biased and non-discriminant firms. I also check the robustness of our main empirical results in several ways. My study has important regulatory and managerial implications in that corporate governance is an important determinant of the readability of disclosure documents. (shrink)

Capacities for abstract thinking and problem‐solving are central to human cognition. Processes of abstraction allow the transfer of experiences and knowledge between contexts helping us make informed decisions in new or changing contexts. While we are often inclined to relate such reasoning capacities to individual minds and brains, they may in fact be contingent on human‐specific modes of collaboration, dialogue, and shared attention. In an experimental study, we test the hypothesis that social interaction enhances cognitive processes of rule‐induction, which (...) in turn improves problem‐solving performance. Through three sessions of increasing complexity, individuals and groups were presented with a problem‐solving task requiring them to categorize a set of visual stimuli. To assess the character of participants’ problem representations, after each training session, they were presented with a transfer task involving stimuli that differed in appearance, but shared relations among features with the training set. Besides, we compared participants’ categorization behaviors to simulated agents relying on exemplar learning. We found that groups performed superior to individuals and agents in the training sessions and were more likely to correctly generalize their observations in the transfer phase, especially in the high complexity session, suggesting that groups more effectively induced underlying categorization rules from the stimuli than individuals and agents. Crucially, variation in performance among groups was predicted by semantic diversity in members’ dialogical contributions, suggesting a link between social interaction, cognitive diversity, and abstraction.
