This article argues that current economic upheaval should be understood as a problem of domination, in two respects: the ‘dyadic’ domination of one actor by another, and the ‘structural’ domination of individuals by a diffuse, decentralized, but nevertheless human-made system. Such domination should be contested through specifically democratic political mobilization, through institutions and practices that expand the political agency of citizens themselves. The article advances this argument by synthesizing two traditions of political thought. It reconstructs radical democratic theory from the (...) Progressive Era. These thinkers in turn help to reinforce contemporary debates in neorepublican thought, resolving disputes over the scope of domination and the relationship between domination and democracy. This synthesis offers a novel normative framework for diagnosing and responding to the current combination of economic upheaval and political dysfunction. (shrink)

This study investigates whether and how the intensity of social distancing from the Coronavirus disease 2019 (COVID-19) pandemic influences the corporate social responsibility (CSR) disclosure index. An empirical examination is carried out based on data from the Shanghai Stock Exchange from 2020 to 2022. CSR disclosure index is measured by the percentage of CSR-related press releases from the total press releases published on a certain day. The intensity of the COVID-19 pandemic is measured by the daily confirmed cases among the (...) population in China. This research uses the two-stage least squares regression model to alleviate the endogeneity issues. Findings reveal a reverse correlation between the intensity of the COVID-19 pandemic and the CSR disclosure. The results are consistent and robust to endogeneity tests and sensitivity analyses. Findings support the stakeholder–agency theory and indicate that Chinese managers tend to satisfy the shareholders' interests rather than those of other broad stakeholders. Moreover, Chinese managers tend to choose short-term survival rather than long-term development in times of social distancing. (shrink)

Many of the discussions about conditionals can best be put as follows:can those conditionals that involve an entailment relation be formulatedwithin a formal system? The reasons for the failure of the classical approachto entailment have usually been that they ignore the meaning connectionbetween antecedent and consequent in a valid entailment. One of the firsttheories in the history of logic about meaning connection resulted from thestoic discussions on tightening the relation between the If- and the Then-parts of conditionals, which in this (...) context was called συναρτησις(connection). This theory gave a justification for the validity of what we todayexpress through the formulae ¬(a → ¬ a) and ¬(¬ a → a). Hugh MacColl and, more recently, Storrs McCall (from 1877 to 1906 and from1963 to 1975 respectively) searched for a formal system in which the validity ofthese formulae could be expressed. Unfortunately neither of the resulting systems is very satisfactory. In this paper we introduce dialogical games with the help of a new connexive If-Then (“→”), the structural rules of which allow the Proponent to develop (formal) winning strategies not only for the above-mentioned connexive theses but also for (a → b) → ¬(a → ¬ b) and (a → b) → ¬(¬ a → b). Further on, we developthe corresponding tableau systems and conclude with some remarks on possibleperspectives and consequences of the dialogical approach to connexivity including the loss of uniform substitution leading to a new concept of logical form.

The work of Hugh MacColl (1837–1909) suffered the same fate after his death as before it:despite being vaguely alluded to and in part even commended, on the whole it has remained an unknown quantity. Even worse, those of his ideas which have played a decisive role in the history of logic have been credited to his successors; this is especially the case with the definition of strict implication and the first formal development of formal modal logic. This paper takes an (...) initial step towards a rectification of this unfortunate misrepresentation, presenting a bibliography of MacColl’s most significant publications with particular regard to their reception.

Martin Buber has always made it clear that his dialogic principle is not to be treated as an abstract conception but an ontological reality. But admittedly, in I And Thou he could only point to such reality and could not properly present it in discursive prose. However there are instances in the text where he strives to do the latter. One particular instance is where he elaborates the emergence of consciousness of “I”. Through this elaboration, what Buber has tried to (...) point at is the bringing forth of the primary word ‘I-It’ forming part of his dialogic principle, as it ‘emerges round about’ the perceptual consciousness realised in body as some sort of a ‘primitive function of knowledge’. However, this still amounts only to an abstract conception, and not to a description of ontological reality as Buber would have aspired for. Hence the thought: what if there exists an endeavour carried out independently of Buber’s work, nevertheless in the same spirit as Buber but without his notorious mixing up of philosophy and religion? There indeed has been such an Existential-phenomenological take on embodiment and perception by the French phenomenologist Maurice Merleau-Ponty, as is laid out in his magnum opus Phenomenology of Perception. In the present paper we will explicate this interesting coincidence, thereby honouring Buber’s aspiration for ontological status to his dialogic principle, at the same time demonstrating how existentially resonating and ontologically converging the thought of these two great thinkers’ have been, though they had totally different intellectual pursuits and concerns.

The Theme. Strong forcing axioms like Martin’s Maximum give a reasonably satisfactory structural analysis of $H(\omega _2)$. A broad program in modern Set Theory is searching for strong forcing axioms beyond $\omega _1$. In other words, one would like to figure out the structural properties of taller initial segments of the universe. However, the classical techniques of forcing iterations seem unable to bypass the obstacles, as the resulting forcings axioms beyond $\omega _1$ have not thus far been strong enough! However, (...) with his celebrated work on generalised side conditions, I. Neeman introduced us to a novel paradigm to iterate forcings. In particular, he could, among other things, reprove the consistency of the Proper Forcing Axiom using an iterated forcing with finite supports. In 2015, using his technology of virtual models, Veličković built up an iteration of semi-proper forcings with finite supports, hence reproving the consistency of Martin’s Maximum, an achievement leading to the notion of a virtual model.In this thesis, we are interested in constructing forcing notions with finitely many virtual models as side conditions to preserve three uncountable cardinals. The thesis constitutes six chapters and three appendices that amount to 118 pages, where Section 1 is devoted to preliminaries, and Section 2 is a warm-up about the scaffolding poset of a proper forcing. In Section 3, we present the general theory of virtual models in the context of forcing with sets of models of two types, where we, e.g., define the “meet” between two virtual models and prove its properties.The main results are joint with Boban Veličković, and partly appeared in Guessing models and the approachability ideal, J. Math. Log. 21 (2021).Pure Side Conditions. In Section 4, we use two types of virtual models (countable and large non-transitive ones induced by a supercompact cardinal, which we call Magidor models) to construct our forcing with pure side conditions. The forcing covertly uses a third type of models that are transitive. We also add decorations to the conditions to add many clubs in the generic $\omega _2$. In contrast to Neeman’s method, we do not have a single chain, but $\alpha $ -chains, for an ordinal $\alpha $ with $V_\alpha \prec V_\lambda $. Thus, starting from suitable large cardinals $\kappa <\lambda $, we construct a forcing notion whose conditions are finite sets of virtual models described earlier. The forcing is strongly proper, preserves $\kappa $, and has the $\lambda $ -Knaster property. The relevant quotients of the forcing are strongly proper, which helps us prove strong guessing model principles. The construction is generalisable to a ${<}\mu $ -closed forcing, for any given cardinal $\mu $ with $\mu ^{<\mu }=\mu <\kappa $.The Iteration Theorem. In Section 5, we use the forcing with pure side conditions to iterate a subclass of proper and $\aleph _2$ -c.c. forcings and obtain a forcing axiom at the level of $\aleph _2$. The iterable class is closely related to Asperó–Mota’s forcing axiom for finitely proper forcings.Guessing Model Principles. Section 6 encompasses the main parts of the thesis. We prove the consistency of the guessing principle $\mathrm {GMP}^+(\omega _3,\omega _1)$ that states for any cardinal ${\theta \geq \omega _3}$, the set of $\aleph _2$ -sized elementary submodels M of $H(\theta )$, which are the union of an $\omega _1$ -continuous $\in $ -chain of $\omega _1$ -guessing, I.C. models is stationary in $\mathcal P_{\omega _3}(H(\theta ))$. The consistency and consequences of this principle are demonstrated in the following diagram. We also prove that one can obtain the above guessing models in a way that the $\omega _1$ -sized $\omega _1$ -guessing models remain $\omega _1$ -guessing model in any outer transitive model with the same $\omega _1$, and we denote this principle by $\rm{SGMP}^+(\omega_3,\omega_1)$.In the following diagram, $\mathrm{TP}$ stands for the tree property; $w\mathrm{KH}$ stands for the weak Kurepa Hypothesis; $\mathrm{MP}$ stands for Mitchell property, i.e., the approachability ideal is trivial modulo the nonstationary ideal; $\mathrm{AP}$ stands for the approachability property; $\mathrm {AMTP}(\kappa ^+)$ states that if $2^\kappa <\aleph _{\kappa ^+}$, then every forcing which adds a new subset of $\kappa ^+$ whose initial segments are in the ground model, collapses some cardinal $\leq 2^{\kappa }$. The dotted arrow denotes the relative consistency, while others are logical implications.Appendices. Appendix A includes merely the above diagram. Appendix B presents a proof of the Mapping Reflection Principle with finite conditions under $\mathrm {PFA}$. Appendix C contains open problems. Finally, the thesis’s bibliography consists of 42 items.Abstract prepared by Rahman MohammadpourE-mail: [email protected]: https://theses.hal.science/tel-03209264. (shrink)

One way to compare different theoretical approaches to the study of technologies is to see what the difference is between their narratives of the construction of a particular technology. In this paper, we re-narrate the bicycle construction from the perspective of actor-network theory (ANT), comparing to SCOT’s first account of the construction. Although SCOT has moved closer to actor-network theory later by paying more attention to co-construction and materliaty, Pinch and Biker have not modified their account of the bicycle development (...) according to these theoretical changes, despite the fact that one decade later Bijker allocated one chapter, ‘king of the road’, to Safety bicycle development again. An ANT’s narrative of bicycle development can provide a basis for a concrete comparison between ANT and the classic version of SCOT. Or it could be argued that this narrative could complement the story of Pinch and Biker of bicycle development. While we present a new narrative of bicycle development in comparison with SCOT’s one, we offer a methodological framework in the ANT literature that can be considered as a methodological procedure to the study of artefacts in general; this framework has three elements: 1. Phenomenal Bracketing, 2. Collective construction, and 3. Co-construction. (shrink)

Lincoln and Guba provided some principles and four evaluative criteria called “trustworthiness” to guide social science research naturalistically. However, drawing on Science and Technology Studies (STS) literature, a field engaged with methods and practices of science for several decades, one can argue that this approach is not still fully naturalistic. In this paper, we review Lincoln and Guba’s four criteria of trustworthiness from an STS perspective. We argue that the STS literature can challenge these criteria, but at the same time (...) they have the potential to be reconstructed with the help of the materials STS provides. (shrink)

This article explores the changing nature of twenty-first-century capitalism with an emphasis on illuminating the political coalitions and institutional conditions that support and sustain it. Most of the existing literature attributes the changing nature of the firm to developments in markets and technology. By contrast, this article emphasizes the political forces that have driven the transformation of the twentieth-century consolidated firm through the firm as a “network of contracts” and toward the platform firm. Moreover, situating the United States in a (...) comparative perspective highlights the distinctive ways US political-economic institutions have facilitated that transformation and exacerbated the associated inequalities.

Drawing from conservation of resources theory, this study investigates the interactive effect of employees’ family-to-work conflict and Islamic work ethic on their helping behavior, theorizing that the negative relationship between family-to-work conflict and helping behavior is buffered by Islamic ethical values. Data from Pakistan reveal empirical support for this effect. Organizations whose employees suffer resource depletion at work because of family obligations can still enjoy productive helping behaviors within their ranks, to the extent that they support relevant work ethics.

Assuming $\mathrm{PFA}$, we shall use internally club $\omega _1$ -guessing models as side conditions to show that for every tree T of height $\omega _2$ without cofinal branches, there is a proper and $\aleph _2$ -preserving forcing notion with finite conditions which specialises T. Moreover, the forcing has the $\omega _1$ -approximation property.

the demise of the logical positivism programme. The answers given to these qu- tions have deepened the already existing gap between philosophy and the history and practice of science. While the positivists argued for a spontaneous, steady and continuous growth of scientific knowledge the post-positivists make a strong case for a fundamental discontinuity in the development of science which can only be explained by extrascientific factors. The political, social and cultural environment, the argument goes on, determine both the questions and (...) the terms in which they should be answered. Accordingly, the sociological and historical interpretation - volves in fact two kinds of discontinuity which are closely related: the discontinuity of science as such and the discontinuity of the more inclusive political and social context of its development. More precisely it explains the discontinuity of the former by the discontinuity of the latter subordinating in effect the history of science to the wider political and social history. The underlying idea is that each historical and - cial context generates scientific and philosophical questions of its own. From this point of view the question surrounding the nature of knowledge and its development are entirely new topics typical of the twentieth-century social context reflecting both the level and the scale of the development of science.

The standard version of the doctrine of double effect, a significant doctrine in applied ethics particularly medical ethics, not only fails to capture some morally significant components of Aquinas’ view, but it does not resort to proper complementary features in order to accommodate the doctrine to our moral intuitions.

We will examine the strength (...) of the formulation applying it into some ethically controversial situations, mainly in medical ethics. (shrink)

Recent literature on dialogical logic discusses the case of tonk and the notion harmony in the context of a rule-based theory of meaning. Now, since the publications of those papers, a dialogical version of constructive type theory (CTT) has been developed. The aim of the present paper is to show that, from the dialogical point of view, the harmony of the CTT- rules is the consequence of a more fundamental level of meaning characterized by the independence of players. We hope (...) that the following paper will contribute to a better understanding of the dialogical notion of meaning.La bibliografía reciente sobre lógica dialógica, estudia el caso de tonk y la noción de armonia en el contexto de una teoría del significado basado en reglas.

El objetivo principal del presente artículo es mostrar que, desde un punto de vista dialógico, la armonía de las reglas de la CTT es consecuencia de un nivel más fundamental de significado caracterizado por la independencia de los jugadores. Esperamos que el presente trabajo contribuya a una mejor comprensión de la nocion dialógica de significado. (shrink)

Ojectives Low energy hip fractures are one of the greatest causes of morbidity and mortality in orthopaedics. This study aims to evaluate written consent forms with respect to basic standards as set out in the Good Practice in Consent Initiative. In particular the stated risks and benefits of each procedure were assessed. Methods 100 consecutive consent forms were reviewed prospectively. The stated procedure, side and complications were recorded. Appropriate signature and legibility was assessed. 13 consultant orthopaedic surgeons were surveyed to (...) identify what risks and benefits they thought should be stated. Results Of 100 consent forms, 31 were for patients who are unable to consent. All 100 consent forms were correctly filled in with patient details and signed. 98% were legible. All stated the side of the operation. The number of complications listed per form ranged from 4 to 11. Infection, bleeding and thromboembolic complications were stated in the majority of consent forms. In total, 30 different complications were recorded; some were only stated once. Discussion and Conclusions This work suggests consent forms are completed well with respect to patient identifiers, legibility and procedure. The variability of complications stated is vast. We suggest standard pre-printed consent forms containing risks and benefits should be used as this may improve standards of informed consent. This has also been recently supported by the British Orthopaedic Association. (shrink)

What are the political implications of a complex image of time, where time does not unfold progressively in a neat linear structure, but where the past is always present and the future impinges on the now? If the past is inescapably present, how do societies that live with grievously injured pasts come to terms with them in the present for the sake of the future? How do they try to address the collective memories of their people, when such memories are (...) marked by violence and conflict, without resorting to vengeance? Drawing from the philosophical writings of Friedrich Nietzsche, this article examines the way in which two countries have recently attempted to negotiate the politics of memory – Algeria and Rwanda. It poses such questions as how much should be forgotten and how much should be remembered? It also asks the difficult question of how such pasts can be overcome and transfigured in the present for the sake of the politics of an affirmative politics of the future. (shrink)

While discussing his notion of objective knowledge Popper introduces the idea of dispensability of knowing subjects, the autonomy of knowledge and the argumentative function of language. The main claim of our paper is that, on our view, objective knowledge produced by argumentative interaction is not achieved by dispensing knowing subjects but by differentiating between the play and the strategic levels of argumentation, where a distinction should be drawn between a particular concrete knowing subject engaged in that interaction, say Karl, and (...) an arbitrary one. Moreover, the theory of meaning deployed at the level of plays, the so-called local meaning, provides already some kind of objective knowledge, since it is player-independent and it does not reduce to the purely logical one of the strategy level. In fact, despite our criticism we think that Popper's discussion of the notion objective knowledge still deserves to be reflected on, particularly so in view of new results concerning the formalization of Brouwer’s Creating Subject and the dialogical interpretation of the notion of epistemic assumption.

« Si la connaissance se donne comme connaissance de la vérité, c’est qu’elle produit la vérité par le jeu d’une falsification première et toujours reconduite qui pose la distinction du vrai et du faux. » Leçons sur la volonté de savoir, Gallimard-Seuil, Paris, 2011 (1re éd. : 1971)."If knowledge is given as knowledge of the truth, it is because it produces the truth by the game of a first, primary falsification renewed again and again which raises the distinction of true (...) and false" [my translation]. Michel Foucault, Lessons on the will to know, Gallimard-Seuil, Paris, 2011 (1st ed.: 1971)I wonder how can Foucault, who refers to Nietzsche as source of inspiration, speak of falsification and deny at the same time objectivity of truth – besides the obvious pun. The challenge of Nietzsche is to contest the objectivity of truth as human desiderata, in such a context Foucault's notion of falsification (of what? falsification of an objective reality?) does either make no sense at all or encodes some other meaning beyond being false – a possible reading would be to take it that Foucault means "distortion", or better “will to deceive “.Perhaps, Foucault's observation amounts to the simple remark that some of the so-called scientific justifications of institutionalized qualifications and anathemas that have important political and socio-economic consequences such as those involving notions as health, disease, or gender do not have the scientific backing they are purported to have (now scientific backing, I guess, must be understood in a rather standard or naïve sense of distinguishing between sciences and pseudo-sciences). This might in some sense be a sensible reflection, and it must be conceded that Foucault had the merit of undertaking extensive and thorough examinations of archives, protocols and reports buried in institutions of various kinds which animated his legendary charming style of writing. Of course, this is quite far away from constituting a revolutionary assault on the notions of (scientific) truth, knowledge and meaning, but, one can say, I think, that his work motivated and still motivates some new approaches to the study of institutional archives. If the reading proposed in the preceding paragraph seems a too meagre result and we are prepared to read Foucault's remarks as involving more thorny epistemological matters, there are of course other ways to delve into them: On one hand I allow me to suggest studying the sceptics of the ancient Greek tradition, or the study of analogical dialectical reasoning within the Arabic Jurisprudence theories of the Middle-Ages (or more generally their theory of Argumentation that has been largely ignored also by the analytic approaches to Argumentation theory and Epistemic Logic), or if one dares to go so far the millenary Jain epistemological lessons on the Art of the Point of View provide plenty to learn from (this constitutes another gap in the recent studies on reasoning and knowledge). On the other one cannot escape the feeling that claims as those of Foucault, though they might be seen as involving interesting questions, many of them have been brought forward without awareness (or perhaps even because of lack of awareness) of the discussions that took place in depth and length in philosophy of logic and knowledge – moreover, as a quick look on nowadays publications bring to the fore, such kind of discussions are nowadays experiencing a creative impulse at a breath-taking pace (particularly so in the context of social sciences). True, analytic philosophers and some philosophers of logic stemming from analytic philosophy quite often ignore history of philosophy or even the history of the science they are purported to study, or more generally philosophical approaches foreign to their own framework – with the result that quite often they produced a rather superficial analysis of the links between knowledge and truth – however, this only points out, that it is time that we start learning each from the other Am I falsifying Foucault? Who knows …. (shrink)

The main idea animating the present paper is that the general aim of debates, such as the one involving the notorious case of the Master Argument, is the ponderation of logical principles by confronting them with some set of assertions and other endorsed principles on the meaning explanation of connectives, quantifiers and modality. As suggested by Seel (2017), the point of the specific case of the MA is about examining Aristotle’s notion of possibility – as implemented by the Possibility Principle (...) (i.e., If it is necessary that if A then B, then B is possible if A is) and the Possibility Rule (i.e., If A is possible, and if B follows from the assumption of A, then B is is possible) in the context of a dialectical debate where it has been asserted that a given proposition is possible, even it is neither true now nor it will ever be, and where at the same time the irrevocability of the past has been endorsed. This suggests to study the MA debate in a setting based on Marion’s (2020) reconstruction of Aristotle’s Dialectical Bouts, adapted to propositions affected by modalities. The setting of Dialectical Bouts for the MA proposed includes•Propositions affected by Reichenbach’s (1948, § 5) three-folded temporal reference, namely: the point of speech S, the point of reference R and the point of the event E. This constitutes our take on Vuillemin’s (1977, 1979, 1984, 1996) suggestion of a “double indexation”.•The dialogical meaning explanation for modalities understood as involving hypotheticals. •The dialogical rules that settle the commitments undertaken when endorsing Aristotle’s Possibility Principle. In fact, in relation to the notion of possibility at work in Vuillemin’s (1996) reconstruction we explored different formulations of the Possibility Rule. Still, there remains a dearth of researches confronting the different formulations of the Possibility Rule with the texts studied by Crubellier (2010) and Rosen and Malink (2012). More generally and coming back to my remarks above, one of the most fruitful insights that can be gained from Vuillemin’s writings on the MA, is that such kind of debates provide an instance of a general pattern for reasoning that I shall call Dialectical Bouts of Material Admissibility (BMA). The rationale behind such kind of argumentation-pattern is to examine the incorporation of new (epistemological, ontological or logical) principles against the background of the commitments undertaken by endorsing a specific set of assertions and meaning explanations. They display the kind of abductive procedure stressed by Crubellier’s (2014) study of syllogism. Under this perspective Ebbinghaus’s (1964) casting of the inferential moves that reduce imperfect syllogisms to perfect ones as implementing an admissibility procedure, represents a logical generalization of the material procedures at stake in the Dialectical Bouts of Material Admissibility. Furthermore if, as stressed by Duthil-Novaes (2005) Medieval Obligations represent a development of Aristotelian Bouts aimed at the ludic exercise of consistency maintenance, DMA should be rather linked to the Islamic tradition of dialectical theory [jadal, munāẓara, ādāb al-baḥth], aimed at the epistemological task of what Young (2017) calls the forging of principles, including legal and deontic ones. In a more contemporary setting, DMA can be related to Brandom’s (2000, pp. 66-77) considerations on Non-Conservative Extensions, where the point of dialectical procedures is put under public Socratic scrutiny the discovery and elucidation of concepts. This general point on Dialectical Bouts of Material Admissibility can be seen as underlying Vuillemin’s project of linking the study of the MA with the classification of philosophical systems.The present paper does not contain a fully developed study on such Dialectical Bouts, but it is rather is an invitation to pick up the gauntlet that Jules Vuillemin threw into the ring.

RésuméAristote n'a pas développé une théorie de la quantification du prédicat, mais une étude récente de Hasnawi a montré qu'Ibn Sīnā a consacré à celle-ci une étude rigoureuse. Assumant la structure aristotélicienne sujet-prédicat, Ibn Sīnā qualifie les propositions qui comportent un prédicat quantifié, de propositions déviantes. Une conséquence de cette approche avicennienne est que la seconde quantification est absorbée par le prédicat. La distinction claire ainsi opérée entre un sujet quantifié, qui pose le domaine de la quantification, et une partie (...) prédicative, qui construit une proposition sur ce domaine, correspond structurellement à la distinction, faite dans la théorie constructive des types, entre le type des ensembles et le type des propositions.Aristote n'a pas non plus combiné son analyse logique de la quantification avec sa théorie ontologique des relations ou de l’égalité. Ibn Sīnā, en revanche, a utilisé les syllogismes qui nécessitent une logique de l’égalité et il a examiné des cas où la quantification se combine, via l’égalité, avec des termes singuliers. En outre, ces réflexions sont essentielles pour sa théorie des nombres qui est fondée sur l'interaction entre l’un et le multiple. Lorsqu'on combine la théorie métaphysique de l’égalité telle qu'on la trouve chez Ibn Sīnā avec son travail sur la quantification du prédicat, il en résulte tout naturellement une logique de l’égalité. En effet, l'interaction entre la quantification du prédicat et l’égalité peut être appliquée aux exemples de syllogismes mentionnés par Ibn Sīnā dans lesquels ces notions interviennent. En utilisant les instruments formels fournis par la théorie constructive des types de Martin-Löf, cet article établit des liens entre la métaphysique d'Ibn Sīnā et son travail logique, liens qui ont été discutés en relation avec d'autres sujets par Thom et Street. Ibn Sīnā n'a pas développé une logique de l'identité, mais il a développé les moyens conceptuels de le faire. (shrink)

The overall objective of the study was to examine the pros and cons of the participatory approach adopted in natural resource management in the ecologically protected areas of the Sundarbans mangrove of Bangladesh. A comparative study was done between the people who are involved and non-involved in this approach. Empirical data was collected through personal interviews with a structured questionnaire. The Gini coefficient was measured first and then embedded with the Lorenz curve to draw a line between perfect equality and (...) inequality vis-a-vis. The study revealed that the co-management built awareness in favor of biodiversity conservation and the efficient use of natural resources. Contradictorily, a segment of different hierarchical committees was involved in destructive activities like poisoning the wetlands for fishing. Therefore, a mixed outcome was found. The findings will help the policymakers in identifying the pitfalls and bottlenecks rooted in co-management. Hence, the study recommends revising the approach to ensure the community’s active participation on an equal basis and take action against them who degrade those resources. Exploring profitable alternative income-generating activities is warranted to narrow down the dependency on the Sundarbans mangrove’s natural resources. In order to address the tragedy of the commons, the study advocates for the unity of all knowledge ranging from science to humanistic scholarship for sound policymaking. (shrink)
