Effective altruism is a growing humanitarian movement with a track record of success in evaluating the effectiveness of charitable spending across a wide range of projects. We suggest ways in which the foundations of this movement can be applied to the complex world of conservation.

We prove that a nonstandard extension of arithmetic is effectively conservative over Peano arithmetic by using an internal version of a definable ultrapower. By the same method we show that a certain extension of the nonstandard theory with a saturation principle has the same proof-theoretic strength as second order arithmetic, where comprehension is restricted to arithmetical formulas.

Drawing from conservation of resources theory, we theorize that spiritual leadership serves as both a resource to enhance employees’ organizational commitment and a passageway to mitigate the negative effects of work–family conflict. Using primary triadic data from leaders, family employees, and nonfamily employees in 77 family firms, results support our theorizing that organizational commitment is enhanced by spiritual leadership but is decreased by work–family conflict. Contrary to theory, however, spiritual leadership exacerbated the negative effects of work–family conflict. (...) Further analysis reveals that family and nonfamily employees respond differently to leadership and work–family stressors. While spiritual leadership has positive effects for family employees, it has negative effects for nonfamily employees experiencing high work–family conflict. (shrink)

The essay title is also the overarching content of the article published in Conservation Letters, August 2023. One of the article’s most notable findings is mentioned as follows: “Specifically, threatened vertebrate fauna with habitat capable of supporting highvalue productive lands received less protection and experienced greater habitat loss.”.

ebec and Queensland, we applied four methods to assess the extent to which environmental surrogates can represent biodiversity components: (1) surrogacy graphs; (2) marginal representation plots; (3) Hamming distance function; and (4) Syrjala statistical test for spatial congruence. For Qu´ebec we used 719 faunal and floral species as biodiversity components, and for Queensland we used 2348 plant species. We used four climatic parameter types (annual mean temperature, minimum temperature during the coldest quarter, maximum temperature during the hottest quarter, and annual (...) precipitation), along with slope, elevation, aspect, and soil types, as environmental surrogates. To study the effect of scale, we analyzed the data at seven spatial scales ranging from 0.01◦ to 0.10◦ longitude and latitude. At targeted representations of 10% for environmental surrogates and biodiversity components, all four methods indicated that using a full set of environmental surrogates systematically provided better results than selecting areas at random, usually ensuring that ≥90% of the biodiversity components achieved the 10%.

In recent years, interest in family-to-work interference and its consequences has increased dramatically. Drawing on conservation of resources theory, we propose and test a dual spillover spiraling model which examines the indirect effects of family incivility on workplace interpersonal deviance through increasing family-to-work conflict (resource loss spiral) and decreasing family-to-work enrichment (resource gain spiral). We also examine the moderating effects of family-supportive supervisor behaviors on these indirect effects. The findings from a three-wave survey, with 455 employees (...) and their coworkers in 60 teams, reveal that experienced family incivility (Time 1) induces more interpersonal deviance at work (Time 3) through facilitating family-to-work conflict (Time 2) and inhibiting family-to-work enrichment (Time 2). Such indirect deviation amplifying effects are mitigated by higher supervisor-level family-supportive supervisor behaviors (Time 1). Theoretical and practical implications are discussed. (shrink)

Workplace incivility has gotten a lot of attention in recent decades. Researchers have looked at many forms of aggressive conduct in the workplace and their negative impacts on individuals and businesses. The goal of this study was to see how incivility among supervisors leads to work withdrawal and when this link might be mitigated. We argued that supervisor incivility indirectly influences work withdrawal behavior through job insecurity, and that emotional intelligence moderates this connection. This study attempted to evaluate the influence (...) of supervisor incivility on the job withdrawal behavior of personnel working in several banks Lahore by drawing on affective events theory and conservation of resource theory. Data were gathered from 350 workers of banks in Lahore, Gujranwala, and Sheikhupura to test our assumptions, and SPSS 24 was used to generate and analyze data with Hayes Process. The findings revealed a strong link between supervisor incivility and job insecurity but no link between supervisor incivility and work withdrawal behavior. The idea of moderation was validated, since emotional intelligence moderates the relationship between job insecurity and job withdrawal behavior. There are also suggestions for more empirical studies and theoretical and practical ramifications. (shrink)

Parents can benefit their offspring by conserving resources that the offspring stand to inherit. Thus, inheritance of resources should promote the evolution of propensities to conserve. But inheritance also has another, less obvious effect: it can reduce the fertility of the conserver’s grandchildren, thus reducing the expected number of great-grandchildren. Consequently, inheritance of resources promotes the evolution of conservation less than might be supposed.

Theoretical and experimental studies on prey–predator systems where predator is supplied with alternate sources of food have received significant attention over the years due to their relevance in achieving biological conservation and biological control. Some of the outcomes of these studies suggest that with appropriate quality and quantity of additional food, the system can be steered towards any desired state eventually with time. One of the limitations of previous studies is that the desired state is reached asymptotically, which makes (...) the outcomes not easily applicable in practical scenarios. To overcome this limitation, in this work, we formulate and study optimal control problems to achieve the desired outcomes in minimum (finite) time. We consider two different models of additional food provided prey–predator systems involving Holling type IV functional response (with inhibitory effect of prey). In the first scenario, additional food is incorporated implicitly into the predator’s functional response with a possibility of achieving biological conservation through co-existence of species and biological control by maintaining prey at a level that is least harmful to the system. In the second, the effect of additional food is incorporated explicitly into the predator’s compartment with the goal of pest management by maintaining prey density at a very minimal damaging level. For both cases, appropriate optimal control strategies are derived and the theoretical findings are illustrated by numerical simulations. We also discuss the ecological significance of the theoretical findings for both models. (shrink)

Provision of additional food supplements for the purpose of biological conservation has been widely researched both theoretically and experimentally. The study of these biosystems is usually done using predator–prey models. In this paper, we consider an additional food provided predator–prey system in the presence of the inhibitory effect of the prey. This model is analyzed in the control parameter space using the control parameters, quality and quantity of additional food. The findings suggest that with appropriate choice of additional food (...) to predators, the biosystem can be controlled and steered to a desirable state. It is also possible to eliminate either of the interacting species. The vital role of the quality and quantity of the additional food in the system dynamics cautions the eco manager on the choice of the additional food for realizing the goal in the biological conservation programme.

Religious conservatives in the U.S. have frequently opposed public-health measures designed to combat STDs among minors, such as sex education, condom distribution, and HPV vaccination. Using Rawls’s method of conjecture, I will clear up what I take to be a misunderstanding on the part of religious conservatives: even if we grant their premises regarding the nature and source of sexual norms, the wide-ranging authority of parents to enforce these norms against their minor children, and the potential sexual-disinhibition effects of (...) the above public-health measures, their opposition to at least one of these measures, HPV vaccination, cannot be justified. In fact, their comprehensive doctrines, when properly interpreted, should lead them to back this measure and thereby draw closer to a policy consensus with other citizens regarding teenage sexual health.

We discuss two desirable properties of deflationary truth theories: conservativeness and maximality. Joining them together, we obtain a notion of a maximal conservative truth theory - a theory which is conservative over its base, but can't be enlarged any further without losing its conservative character. There are indeed such theories; we show however that none of them is axiomatizable, and moreover, that there will be in fact continuum many theories of this sort. It turns out in effect that the deflationist (...) still needs some additional principles, which would permit him to construct his preferred theory of truth. (shrink)

The Exclusion Argument for physicalism maintains that since (1) every physical effect has a sufficient physical cause, and (2) cases of causal overdetermination are rare, it follows that if (3) mental events cause physical events as frequently as they seem to, then (4) mental events must be physical in nature. In defence of (1), it is sometimes said that (1) is supported if not entailed by conservation laws. Against this, I argue that conservation laws do not lend sufficient (...) support to (1) to render its denial ‘unscientific’, and that those who accept (3) and deny (4) may consequently respond to the Exclusion Argument by denying (1) without thereby setting themselves at odds with current science. I also argue that conservation laws are compatible with (3) and the negation of (4), and that one can therefore accept conservation laws and (3) while denying both (1) and (4). (shrink)

Conservation biology is a discipline with the explicit goal of protecting species from extinction. We examine how conservation biologists represent at-risk species, how they navigate values and ethical tensions in the discipline, and how they might be more effective in reaching conservation goals. While these topics are discussed in the literature, we offer a unique empirical examination of how individuals perceive and perform conservation work. We conducted 29 interviews with conservation biologists and found that most (...) respondents viewed their work as providing information but also felt that other species have intrinsic value and we should extend our ethical standards to include other species. However, many attempted to separate science from values, and some felt it was necessary to hide their values and ethical positions and avoid advocacy. While conservation biologists navigate these tensions differently, those who engage in advocacy will likely be more effective in reaching conservation goals. Current societal values and views on ethical extension, rather than a lack of science, represent the most significant impediment to addressing the extinction crisis. (shrink)

The article examines the case of springtime bird hunting in Åland from a moral point of view. In Åland springtime hunting has been a cultural practice for centuries but is now under investigation due to the EU Directive on the protection of birds. The main question of the article is whether restrictions on bird hunting have a sound basis. We approach this question by analysing three principles: The animal rights principle states that if hunting is not necessary for survival, it (...) cannot be morally justified. Therefore hunting merely to engage in a cultural custom is morally suspect. In the light of the species conservation principle the hunting is questionable due to the fact that it seems to have a diminishing effect on the species populations. The formal principle of justice makes up a more difficult question since the special position of the minorities in regard to the use of natural resources is generally recognised so that they have the right to maintain their cultural practices. We claim, however, that even though cultural practices have substantial value and can be the object of special rights, they should be coherent with other principles. The springtime bird hunt in Åland does not accord with the relevant moral principles and for this reason we conclude that the basis for its continuation is weak. (shrink)

ABSTRACTA careful look at societies facing threat reveals a unique phenomenon in which liberals and conservatives react emotionally and attitudinally in a similar manner, rallying around the conservative flag. Previous research suggests that this rally effect is the result of liberals shifting in their attitudes and emotional responses toward the conservative end. Whereas theories of motivated social cognition provide a motivation-based account of cognitive processes, it remains unclear whether emotional shifts are, in fact, also a motivation-based process. Herein, we propose (...) that under threat, liberals are motivated to feel existential concern about their group’s future vitality to the same extent as conservatives, because this group-based emotion elicits support for ingroup protective action. Within the context of the Palestinian-Israeli conflict, we tested and found support for this hypothesis both inside and outside the laboratory. We d... (shrink)

This paper discusses two conservative ways of treating evidence. (I) Closing inquiry involves discounting evidence bearing on one's belief unless it is particularly strong evidence; (II) biased assimilation involves dedicating more investigative resources to scrutinizing disconfirming evidence (than confirming evidence), thereby increasing the chances of finding reasons to dismiss it. It is natural to worry that these practices lead to irrational biases in favor of one's existing beliefs, and that they make one's epistemic condition significantly path-sensitive by giving a bigger (...) role to batches of evidence obtained earlier in the course of inquiry compared with those subsequently acquired. However, I argue that both practices are demanded by considerations of practical rationality. I also argue that, contrary to initial appearances, there is little reason to worry about the effects of these practices on the dynamics of one's beliefs. (shrink)

The Australian nature conservation movement is effectively entering its second century of existence and this transition has prompted a degree of reflection about the strategies used hitherto. After going through boom years – as part of a broader environmental movement – from the 1970s until the early 1990s, a more difficult political environment in the second half of the 1990s has sparked a semi-public discussion about priorities and future strategies. This article argues that the debate about future conservation (...) strategies needs to tackle two important legacies that have become increasingly problematic: a lingering 'frontier mentality' that fosters a separation between people and 'pristine nature'; and a heavy reliance on scientific expertise and rational arguments for conservation. This dual legacy has blinded the movement to the aesthetic appeal of the romantic philosophical tradition in ecology and the importance of sensuous, embodied experiences of the 'more than human' world. In rethinking the legacy of the romantic philosopher Henry David Thoreau, the article argues for a shift of emphasis from wilderness to wildness in order to bring conservation home to more people. It suggests that we can learn from the ability of Australian Aborigines to listen to the land in order to 'sing up' the stories that are embedded in landscapes. Learning to read and create landscape stories provides creative ways of building more affective bonds between people and the land. Non-rational approaches to nature conservation can help to re-enchant conservation ' work '. (shrink)

Philosophers have paid little attention to the distinction between conservation and preservation, apparently because they have accepted John Passmore’s suggestion that conservationism is an expression of anthropocentric motives and that “true” preservationism is an expression of nonanthropocentric motives. Philosophers have therefore concentrated their efforts on this distinction in motives. This reduction,however, is insensitive to important nuances of environmentalist objectives: there are a wide variety of human reasons for preserving natural ecosystems and wild species. Preservationist policies represent a concem to (...) protect biological diversity from the simplifying effects of human management and are motivated by the full range of values (consumptive, aesthetic, scientific, and moral) attached to a diverse biota.Conservationists and preservationists differ mainly in their emphasis on resilience measures versus predictability measures of stability, respectively. The distinction between anthropocentric and nonanthropocentric motives loses importance as emphasis is placed on the longest term values humans place on the proteetion of biological diversity.

In 1959, the Charles Darwin Station and the Galápagos National Park were established, formally inaugurating conservation on the archipelago. In the same year, a utopian colony from the United States arrived. Whereas scholars have dismissed the latter and focused on the former, this essay unveils the science-inspired utopianism common to both enterprises. Investing science with the exclusive role of producing all knowledge and steering politics, leaders of the two initiatives aspired not only to protect nature but also to forge (...) a new humanity. Describing how such ambitions burst along lines of race, class, and nationality, I argue that these enterprises consolidated the current understanding of the Galápagos as “pristine”: a site fit for research and tourism but unhospitable to people. Drawing on archival and historical documents, this essay aims to reinvigorate two conversations: one between science and technology studies and conservation, and the other between STS and utopian studies. If recent attempts at bridging the divide between science and imagination have emphasized how powerful actors shape human society, this essay considers the long-lasting effects of scientific imaginaries on a politics of nature.

This open access book features essays written by philosophers, biologists, ecologists and conservation scientists facing the current biodiversity crisis. Despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so?The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing (...) conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.

_Moral Politics_ takes a fresh look at how we think and talk about political and moral ideas. George Lakoff analyzed recent political discussion to find that the family—especially the ideal family—is the most powerful metaphor in politics today. Revealing how family-based moral values determine views on diverse issues as crime, gun control, taxation, social programs, and the environment, George Lakoff looks at how conservatives and liberals link morality to politics through the concept of family and how these ideals diverge. Arguing (...) that conservatives have exploited the connection between morality, the family, and politics, while liberals have failed to recognized it, Lakoff explains why conservative moral position has not been effectively challenged. A wake up call to political pundits on both the left and the right, this work redefines how Americans think and talk about politics. (shrink)

A basic result in intuitionism is Π02-conservativity. Take any proof p in classical arithmetic of some Π02-statement , with P decidable). Then we may effectively turn p in some intuitionistic proof of the same statement. In a previous paper [1], we generalized this result: any classical proof p of an arithmetical statement ∀x.∃y.P, with P of degree k, may be effectively turned into some proof of the same statement, using Excluded Middle only over degree k formulas. When k = 0, (...) we get the original conservativity result as particular case. This result was a by-product of a semantical construction. J.

In this paper I offer an 'integrating account' of singular causation, where the term 'integrating' refers to the following program for analysing causation. There are two intuitions about causation, both of which face serious counterexamples when used as the basis for an analysis of causation. The 'process' intuition, which says that causes and effects are linked by concrete processes, runs into trouble with cases of 'misconnections', where an event which serves to prevent another fails to do so on a (...) particular occasion and yet the two events are linked by causal processes. The chance raising intuition, according to which causes raise the chance of their effects, easily accounts for misconnections but faces the problem of chance lowering causes, a problem easily accounted for by the process approach. The integrating program attempts to provide an analysis of singular causation by synthesising the two insights, so as to solve both problems. In this paper I show that extant versions of the integrating program due to Eells, Lewis, and Menzies fail to account for the chance-lowering counterexample. I offer a new diagnosis of the chance lowering case, and use that as a basis for an integrating account of causation which does solve both cases. In doing so, I accept various assumptions of the integrating program, in particular that there are no other problems with these two approaches. As an example of the process account, I focus on the recent CQ theory of Wesley Salmon (1997). (shrink)

A Krom formula of pure quantification theory is a formula in conjunctive normal form such that each conjunct is a disjunction of at most two atomic formulas or negations of atomic formulas. Every class of Krom formulas that is determined by the form of their quantifier prefixes and which is known to have an unsolvable decision problem for satisfiability is here shown to be a conservative reduction class. Therefore both the general satisfiability problem, and the problem of satisfiability in finite (...) models, can be effectively reduced from arbitrary formulas to Krom formulas of these several prefix types.

This paper aims to investigate how workplace ostracism acts as a motive behind customer service sabotage. We examine the role of stress as a meditating variable along with the moderation of perceived organizational support (POS) on the said association by using conservation of resources and equity theory. 217 nurses from hospitals of southern Punjab region in Pakistan participated in the study. Data was collected through survey and structured questionnaires. SPSS and AMOS were used to analyze data with latest techniques (...) of bootstrapping and process macros. The results showed that stress mediated between the association of workplace ostracism and service sabotage behavior. Perceived organizational support was confirmed as a moderator between this relationship. POS buffered the harmful effects of ostracism and stress on customer service, as POS demonstrates to personnel that they are cherished and respected by the organization which lessens the strength of perceived stress due to workplace ostracism. Organizational leadership should take advantage from stress-alleviating effect of POS, which is important in producing adequate levels of work-performance. (shrink)

Prior research on the influence of various ways of framing anthropogenic climate change do not account for the organized ACC denial in the U.S. media and popular culture, and thus may overestimate these frames' influence in the general public. We conducted an experiment to examine how Americans' ACC views are influenced by four promising frames for urging action on ACC —when these frames appear with an ACC denial counter-frame. This is the first direct test of how exposure to an ACC (...) denial message influences Americans' ACC views. Overall, these four positive frames have little to no effect on ACC beliefs. But exposure to an ACC denial counter-frame does significantly reduce respondents' belief in the reality of ACC, belief about the veracity of climate science, awareness of the consequences of ACC, and support for aggressively attempting to reduce our nation's GHG emissions in the near future. Furthermore, as expected by the Anti-Reflexivity Thesis, exposure to the ACC denial counter-frame has a disproportionate influence on the ACC views of conservatives, effectively activating conservatives' underlying propensity for anti-reflexivity.

Applications to proofs in classical analysis, especially uniqueness proofs in approximation theory, will be given in subsequent papers. (shrink)

We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

Against the historically widespread view that divine conservation is a continuation of the act of creation, William Lane Craig argues that conservation is a different kind of act since, unlike creation ex nihilo, it is diachronic and it acts on a patient. Timothy Miller poses a timing objection against Craig's view, arguing that on such a view either the existence of a conserved entity is discontinuous, or the conserving activity overdetermines its effect, or the conserving activity is not (...) continuous. The present paper explores the options that remain for a diachronic, agent-patient account of conservation. It includes several models of conservation on which divine activity is continuous but not overdetermined since its effect at each time is something less specific than the existence of a created being at a time.

One interesting feature of de‐extinction—particularly with respect to long‐extinct species such as the passenger pigeon, thylacine, and mammoth—is that it does not fit neatly into the primary rationales for adopting novel ecosystem‐management and species‐conservation technologies and strategies: efficiency and necessity. The efficiency rationale is that the new technology or strategy enables conservation biologists to do what they already do more effectively. Why should researchers embrace novel information technologies? Because they allow scientists to better track, monitor, map, aggregate, and (...) analyze species behaviors, biological systems, and human‐environment interactions. This enables better decision‐making about how to protect species, which areas to conserve, and how to reduce anthropogenic impacts on ecological systems. Many projects in conservation genomics are justified in this way. But de‐extinction is not a more efficient or necessary means to some conservation aim that is already recognized as acceptable or important. In fact, because it is focused on reconstituting approximations of nonexistent species, rather than maintaining extant ones, the social and ethical assessment of de‐extinction is not limited to asking whether it is a good means. We can ask as well whether de‐extinction is a worthwhile “conservation” goal in the first place. (shrink)

Surface acting is a heavy emotional and cognitive task practiced by nurses, which has negative consequences on their wellbeing.

Most accounts of the effect of the global marketplace on deforestation in Africa, Asia, and Latin America emphasize the demand for timber used in industrial processes and the conversion of tropical forests to pastures for beef cattle.

Although increased demand for NTFPs rarely results in massive deforestation, the depletion of the raw materials needed to make (...) particular products is common.Many rural households in the Mexican state of Oaxaca have prospered over the past three decades through the sale of brightly-painted, whimsical wood carvings (alebrijes) to international tourists and the owners of ethnic arts shops in the United States, Canada, and Europe. This paper examines a promising project aimed at providing Oaxacan alebrije-makers with a reliable, legal, and sustainable supply of wood. The ecologists, artisans, merchants, and forest owners involved in the project face formidable obstacles. Gaining permission to harvest wood from land belonging to Oaxacan communities requires the negotiation of a complex social, legal, economic, and political landscape. Artisans’ decisions about where to obtain wood rest largely on price, quality, and reliability of the supplier; they are willing to pay a premium for ecologically sustainable wood only if the additional cost can be passed on to consumers. Nonetheless, a group of carvers has begun to buy sustainably harvested wood. This arrangement has economic advantages for both the alebrije-makers and the owners of the forests where the wood is produced. (shrink)

Ethics has been identified as an important factor that potentially affects auditors’ professional skepticism. For example, prior research finds that auditors who are more concerned with professional ethics exhibit greater professional skepticism. Further, the literature suggests that professional skepticism may lead the auditor to more vigilantly resist the client’s position in financial reporting disputes. These reporting disputes are generally resolved through negotiations between the auditor and client to arrive at the final reported amounts. To date, the role that professional skepticism (...) potentially plays in the negotiation process has been relatively unexplored. The literature prior to the enactment of Sarbanes–Oxley (SOX) suggests that auditors are more likely to approve a client position when the matter in dispute is relatively ambiguous and when changing the client’s position will result in the client failing to meet analysts’ expectations. However, changes resulting from SOX have led auditors to be more vigilant and therefore results found in the pre-SOX environment may not hold in the current environment where auditors are held more accountable for their actions. Results from an experiment with experienced audit managers and partners suggest that in the post-SOX climate, auditors’ negotiations do not appear to be substantively influenced by management being able to meet or beat forecasts. Moreover, we find that when auditors exhibit heightened professional skepticism, they are more ethical by being conservative and they stand more resolute than when auditors do not exhibit heightened professional skepticism. Finally, although we do not find a main effect for the influence of earnings forecast, we do find a significant interaction between earnings forecast and heightened professional skepticism. Implications for practice and research are then presented. (shrink)

Men's gender ideologies have changed more slowly than women's since the 1970s; this article analyzes the period and cohort processes that underlie men's attitude change and how the individual-level characteristics of conservative men differ by birth cohort. Using multidimensional measures of gender role attitudes from the 1974-1998 General Social Surveys, the author finds that changes in men's attitudes have been brought about both by period influences, especially during the 1970s, and by cohort replacement. Analyses of multivariate interaction effects demonstrate (...) that education has become a much less significant predictor of attitudes for men born after 1945. (shrink)

Despite recent strides in the direction of achieving a more equitable and genuine place for Indigenous voices in the conservation conversation, the conservation movement must more deliberately and thoroughly grapple with the legacy of its deeply settler colonial history if it is to, in actuality and not merely in rhetoric, achieve the aim of being more equitable. In this article, we show how the conservation movement, historically and still largely today, traffics in certain ethical and political values (...) that are, in principle or in effect, anti-Indigenous. Through this examination, we hope to reveal how present-day conservation efforts, even if ‘well-meaning’ or nominally deferential regarding Indigenous peoples and perspectives, in fact reinforce settler colonial structures. In particular, we critique the notion of the uninhabited wilderness as a conservation ideal and the disavowal of originary violence (along with a parallel positing of settler nativism) in the articulation of conservation historicity and the founding of conservation movements. We conclude by offering some steps conservationists can take to alter their practices, methods, and values in ways that recognize, respect, and reciprocate with Indigenous peoples. (shrink)

We consider several thought and practical experiments, and variations thereof, from which the existence can be inferred of retroactive effects on the assumptions of conservation of linear and angular momentum and of realism defined in a wide sense.

In one of the experiments considered, the evidence of retroactivity (...) is more striking and can more easily be actually demonstrated than was the case in earlier proofs. (shrink)

We describe a prey–predator system incorporating constant prey refuge through provision of alternative food to predators. The proposed model deals with a problem of non-selective harvesting of a prey–predator system in which both the prey and the predator species obey logistic law of growth. The long-run sustainability of an exploited system is discussed through provision of alternative food to predators. We have analyzed the variability of the system in presence of constant prey refuge and examined the stabilizing effect on predator–prey (...) system. The steady states of the system are derived and dynamical behavior of the system is extensively analyzed around steady states. The optimal harvesting policy is formulated and solved with the help of Pontryagin’s maximal principle. Our objective is to maximize the monetary social benefit through protecting the predator species from extinction, keeping the ecological balance.

Unlike vague scientific or artificial expressions, however, vague natural language expressions do not display the kind of vagueness that we associate with the sorites; they rather display what I call cluster vagueness. A non-trivial consequence of this is that those legal definitions that state precisifications of natural language concepts not only add aspects of meaning to existing expressions but also effectively change the meanings of these expressions. From (...) this, in turn, it follows that we should avoid precisifying ordinary expressions with the help of legal definitions to the extent that we wish legal language to be in line with natural language. And being in line with natural language may help us to deal with gaps in our laws at the very moment we become aware of them, and not just afterwards. (shrink)

As the international momentum of the school effectiveness movement continues, its exponents remain largely impervious to criticism. This paper argues that while they may not readily align themselves with the individualistic aspects of Conservative social philosophy, their methodology necessarily secretes an atomised social ontology. The charge of ideological commitment rests on the fact that the essentially positivist epistemology employed by school effectiveness researchers presupposes an ontology of closed systems and atomistic events. Thus any notion of the structuring of life-chances is (...) automatically ruled out of court. The reciprocity of social ontology and methodology is explored in order to account for the myopia of the school effectiveness movement. (shrink)
